The ancient Romans built incredible constructions using concrete. From a wide system of roads and aqueducts—some of which are in use today—to temples and stadiums, their buildings have stood the test of time. The best example of the use of their incredible building material is the Pantheon, which exemplifies ancient Rome’s brilliance by having the world’s largest unreinforced concrete dome still intact despite being dedicated almost 2000 years ago.
In comparison to modern concrete, historians, archeologists, and engineers have always wondered why Rome’s concrete has lasted so long, especially since today, we can barely keep roads from getting potholes.
News recently broke that researchers may have finally found the answer by isolating “the ingredient that allows Roman concrete to ‘self-heal,’ making it stronger than its modern equivalent. Their ‘back to the future’ findings could help reduce the environmental impact of cement production in today’s society.”
Now, an international team has discovered ancient concrete-manufacturing techniques that incorporated several key ‘self-healing’ properties. For years, researchers believed the key to the ancient concrete’s durability was one ingredient: pozzolanic material, such as volcanic ash from the area of Pozzuoli, on the Bay of Naples.
Previously disregarded as merely evidence of sloppy mixing practices, or poor-quality raw materials, the new study suggests that these tiny lime clasts gave the concrete a previously unrecognized self-healing capability. ‘The idea that the presence of these lime clasts was simply attributed to low quality control always bothered me,’ said MIT professor of civil and environmental engineering Admir Masic. ‘If the Romans put so much effort into making an outstanding construction material, following all of the detailed recipes that had been optimized over the course of many centuries, why would they put so little effort into ensuring the production of a well-mixed final product? There has to be more to this story.’”
Masic and his team have now provided an incredible answer to why Roman concrete looked the way it did.
MIT explains: For many years, researchers have assumed that the key to the ancient concrete’s durability was based on one ingredient: pozzolanic material such as volcanic ash from the area of Pozzuoli, on the Bay of Naples. This specific kind of ash was even shipped all across the vast Roman empire to be used in construction, and was described as a key ingredient for concrete in accounts by architects and historians at the time.
Historically, it had been assumed that when lime was incorporated into Roman concrete, it was first combined with water to form a highly reactive paste-like material, in a process known as slaking. But this process alone could not account for the presence of the lime clasts. Masic wondered: “Was it possible that the Romans might have actually directly used lime in its more reactive form, known as quicklime?”
Studying samples of this ancient concrete, he and his team determined that the white inclusions were, indeed, made out of various forms of calcium carbonate. And spectroscopic examination provided clues that these had been formed at extreme temperatures, as would be expected from the exothermic reaction produced by using quicklime instead of, or in addition to, the slaked lime in the mixture. Hot mixing, the team has now concluded, was actually the key to the super-durable nature.
“The benefits of hot mixing are twofold,” Masic says. “First, when the overall concrete is heated to high temperatures, it allows chemistries that are not possible if you only used slaked lime, producing high-temperature-associated compounds that would not otherwise form. Second, this increased temperature significantly reduces curing and setting times since all the reactions are accelerated, allowing for much faster construction.”
During the hot mixing process, the lime clasts develop a characteristically brittle nanoparticulate architecture, creating an easily fractured and reactive calcium source, which, as the team proposed, could provide a critical self-healing functionality. As soon as tiny cracks start to form within the concrete, they can preferentially travel through the high-surface-area lime clasts. This material can then react with water, creating a calcium-saturated solution, which can recrystallize as calcium carbonate and quickly fill the crack, or react with pozzolanic materials to further strengthen the composite material. These reactions take place spontaneously and therefore automatically heal the cracks before they spread. Previous support for this hypothesis was found through the examination of other Roman concrete samples that exhibited calcite-filled cracks.
Science noted, “When the team created small cracks in the concrete—as would happen as the material aged—and then added water (as would happen with rainwater in the real world), the lime lumps dissolved and recrystallized, effectively filling in the cracks and keeping the concrete strong, the researchers report today in Science Advances. “This has an incredible impact,” Masic says.
Modern concrete typically doesn’t heal cracks larger than 0.2 or 0.3 millimeters across. The team’s Roman-inspired concrete, in contrast, healed cracks up to 0.6 millimeters across.
Masic hopes the work will inspire today’s engineers to improve their own concrete, perhaps with quicklime or a related compound. Indeed, he says, a startup concrete company plans to employ the new discovery. The material wouldn’t just be less expensive than current self-healing concrete, Masic says, it could also help fight climate change: Cement production accounts for 8% of greenhouse gas emissions.”
Who knows, maybe soon we’ll have smoother roads. If we do, it’ll be the ancient Romans who deserve our thanks.

The Loxton River Vessel Waste Disposal Station on the River Murray will receive a $1.3 million upgrade thanks to State Government funding.
“Waste disposal stations play a vital role in maintaining the health of the River Murray,” Mr Whetstone said. “The stations, including this one at Loxton, enable boats to pump out sewage and grey water, reducing the risk of pollutants getting into the river – including disease-causing bacteria such as E. coli and nutrients that can cause algal blooms.”
“With about 1,700 houseboats currently registered in South Australia, the facilities have been well used during the past 40 years. This is the eleventh waste disposal station to be upgraded in recent times, with a further two river waste stations due to be modernised in the coming years.”
“These facilities are vital for our houseboat operators who play a key role in maintaining a sustainable tourism industry in our region.”
The upgrade will involve the installation of new piling, a floating platform, gangway and a new septic system connected to the Loxton sewerage system.
The modernisation works will allow the station to take both grey and black water, increase pumping capacity and accommodate vessels up to 80 tonnes.
Works are expected to begin later this month and be completed by late 2020. The station will be closed during the upgrade and alternative waste disposal facilities will be provided.
River vessel operators can dispose of their waste at the 13 public waste disposal stations located at regular distances along the South Australian River Murray - at Lock 6, Renmark, Berri, Loxton, Lock 3, Waikerie, Morgan, Blanchetown, Swan Reach, Walker Flat, Mannum, Murray Bridge and Goolwa.
The stations are available for the disposal of three types of waste including black water (sewage waste), grey water (water that has been used for washing, laundering, bathing or showering) and general or galley waste.


Ensuring Quality Public Transit Options
The Washington Metropolitan Area Transit Authority’s (WMATA’s) recent push to complete large-scale, safety-related construction projects—also known as the SafeTrack initiative—has made traveling via the Metro rail and bus system harder for everyone. There are fewer trains and longer wait times between trains, which makes every trip on the Metro system take longer.
I acknowledge that these types of safety improvement projects are necessary, but that doesn’t give Metro a free pass to provide poor quality service on parts of the system that aren’t undergoing construction. If anything, the inconveniences of SafeTrack mean that Metro must do better to ensure quality public transportation options on Metro buses and rail lines not affected by SafeTrack.
To ensure quality public transit options for Mount Pleasant, if elected Advisory Neighborhood Commissioner, I will advocate for the following actions:
Add more 42 and H2/H4/H8 buses to run on the weekends and during the weekdays outside of rush hour.
Encourage the District Department of Transportation (DDOT) to ban parking on and add dedicated bus lanes to 16th Street from Colorado Avenue all the way down to Farragut Square.
Advocate for doubling of bus service (through increased funding, supported by increased tax revenue) of buses on the 16th Street and 14th Street corridors.
Resist any effort by Metro to further reduce Metro rail’s operational hours, especially as closing Metro for any more time during the week would adversely affect Mount Pleasant residents’ ability to get to and from late-night jobs.

Have you ever wondered what the future of transportation might look like? With the increasing traffic on our roadways, from traffic jams to cities filled with smog, our current state of transportation doesn’t seem to be adequate in moving people from point A to point B. So what is the answer?
Magnetic levitation seems to be on the radar for futuristic transportation.
What is Maglev? It’s a method by which a vehicle is suspended in the air by using magnetic force to counter gravitational force that pulls the vehicle toward the ground. The technology has been tested on cars.
Maglev technology is in contrast to hovercraft technology, in which vehicles are cushioned on a bed of air. Magnetic forces are already in use today driving trains. Happy Motoring.”


Guard rail, as the name implies guards something. In an industrial setting, guardrail protects machinery that provides an efficient and safe working environment. Guardrails protect people. Heavy material handling vehicles are common in industries. Guardrails can protect people from any danger, even on the roads.
Benefits of highway guardrails
- Longevity: Guardrails have a longer life and don’t require replacement soon. It can stay for years and needs a replacement only when it wears out.
- Fast and easy installation: Guardrails are easy to install, but professionals have to handle the installation part. Uniform cutting of guardrails can help in quicker installation.
- Corrugated strength: Guardrails are strong and won’t collapse without any harsh impact. Once they get installed, they can withstand different types of forces and actions that cause stress on their design.
Different types of guardrails
Have a look at few of the guardrails available for different purposes:
- Bolted guardrail: It provides an inexpensive, and easy to see protective barrier for people and equipment.
- Lift out guardrail: They help in easy removal of rail sections for convenient access to equipment. These guardrails are visible in an industrial setup.
While guardrails offer protection on a macro level, safety bollards provide micro-level protection. Safety bollard can prevent damage to machinery and equipment in an industrial setup. They are also meant to be visual aids that guide traffic and restrict access for vehicles in particular areas.
A pipe safety bollard can have tighter curves than a guardrail as it can allow enough room for a person on foot to pass around them. Different safety bollards exist for a wide range of applications outside of industrial zones.
Uses of safety bollards
- Offers security and protection: Safety bollards are installed for safety, crash prevention and shock absorption. If a driver loses control and crashes, safety bollards can reduce the impact of the collision. Installing safety bollards can also prevent damage to property.
- Visual barrier: These serve as barriers in different ways. They are useful in parking lots and warehouses where vehicles are continuously on the move. Installing bollards in parking lots can avoid drivers speeding in and crashing.
- Architectural ornamentation: Aside from protecting people and property, safety bollards can serve as an ornamental purpose. However, whether used indoors or outdoors, these should be durable.
- Security for buildings and infrastructure: Buildings that have safety bollards installed can avoid major crashes of vehicles. The security of buildings like banks, schools, offices etc. can be drastically improved by installing bollards.
- Pedestrian safety: Unsafe crosswalks, crowded streets or poor traffic signals may cause fatal crashes that can be a threat to the lives of people. Having bollards installed ensures the safety of pedestrians from being injured by vehicles crashing into them.
Bollards merely don’t define boundaries or protect buildings and infrastructure. They are also an inevitable part of road safety. Heavy-duty bollards, if installed correctly, can increase traffic safety while not impacting the visual appearance of the site. They help alert drivers on narrow roads and high curbs to manage vehicle flow in high traffic roads. Bollards can also prevent vehicles from hitting the sidewalk, injuring or killing pedestrians


If you’d like to give definition and style to your yards, you could install surfacing materials such as landscaping bricks. Landscaping bricks are an excellent investment and can last for years. However, some landscaping bricks could sink over time, ruining your garden’s look.
Here are 10 ways to keep landscaping bricks from sinking:
- Excavate the yard before installing landscaping bricks.
- Check yard drainage before installing landscaping bricks.
- Create a strong base before laying the landscaping bricks.
- Lay the landscaping bricks properly.
- Sand the joints of the landscaping bricks properly.
- Use a joint stabilizing sealer.
- Install edge restraints around the landscaping bricks.
- Maintain the landscaping bricks regularly.
- Take good care of the landscaping bricks.
- Hire professionals to install the landscaping bricks.
After reading this article, you’ll learn some great tips to keep your landscaping bricks from sinking. These tips will help you before, during, and after the installation of landscaping bricks to prevent any sinkage.
1. Excavate the Yard Before Installing Landscaping Bricks
Installing landscaping bricks is an investment, and you should take the project seriously for the best results. The best way to prepare is by excavating the yard before installing landscaping bricks.
Excavation involves digging the ground where you plan to install the landscaping bricks so that they have a flat surface to be laid on.
Excavation of the yard before installing landscaping bricks helps to:
- Determine the depth of the excavation depending on various factors such as site drainage and type of soil.
- Ensure the water table isn’t too high. A high water table affects drainage, and the soil may eventually shift even if you lay a good base.
- Determine the minimum and maximum height the landscaping bricks should reach.
- Keep the landscaping bricks from sinking and prevent other issues that may arise if you don’t excavate.
If you have the expertise and the right tools, and you are looking for an excuse to get into shape, you can excavate by yourself. Otherwise, you can use the services of a professional masonry contractor or a landscaping company.
2. Check Yard Drainage Before Installing Landscaping Bricks
During excavation, you’ll find out about your yard’s drainage. You’ll learn how the surface water will drain naturally from that part of the yard, which is important to know before installing landscape bricks.
For instance, the water won’t drain properly if the section has no slope or gradient. The water could eventually accumulate under the landscaping bricks and cause soil erosion.
If the soil under the landscaping bricks erodes, they could eventually sink. Some ways of ensuring proper drainage in your yards before installing landscaping bricks include:
Ensuring That the Slab Slopes Correctly
When constructing the slab for landscaping bricks, it should slope downwards away from the building to enable proper water drainage.
When the water drains properly from the landscaping bricks, the chances of the water washing away the joint sand decrease. As a result, the chances of landscaping bricks sinking over time decreases.
Installing a French drain
Some areas have poor drainage due to one reason or another. If your region has a problem with sinkholes or standing water, then it’s best to install a French drain before laying landscaping bricks.
A French drain is a perforated pipe you place underground to help drain excess water from an area that has poor drainage (source).
3. Create a Strong Base Before Laying the Landscaping Bricks
One of the reasons why landscaping bricks sink is because of improper installation. Improperly installed landscaping bricks can sink over time, causing a structurally and aesthetically devastating outcome.
Proper installation of landscaping bricks starts with creating a strong and durable base.
Creating a good base is critical when installing landscaping bricks in your yards. The base is the foundation of your landscaping bricks installation project.
If you don’t prepare the foundation properly, then the project could eventually fail, leading to the sinking of the landscaping bricks and other issues.
Creating a strong and durable base before laying the landscaping bricks includes:
Clearing and Leveling the Ground
It’s crucial to clear the ground where you will install the landscaping bricks. Clearing includes removing grass, stones, and debris from the section in readiness for the base materials.
Leveling the ground is also essential. The landscaping bricks could eventually sink if the land has dipped.
Using Durable Base Materials
The durability of the base materials determines if your landscaping bricks will sink over time. The reason is that using inappropriate materials can gradually cause shifting of the base.
The landscaping bricks could eventually start sinking if the ground is shaky and unstable.
Some of the durable materials you could use to create a strong and stable base are:
- Crushed rock
- Bedding sand
Crushed rock and bedding sand can withstand tear and wear and prevent water from seeping to the ground below the landscaping bricks. If you construct the base properly using these materials, the foundation can remain intact for years.
Ensuring the Base Materials Compact Properly
If the base materials don’t compact well before you lay the landscaping bricks, then the base won’t become strong or durable enough for the bricks.
Although you can do the compacting manually, you can also use a compacting machine for quicker results.
A well-compacted base is essential because:
- It helps the landscaping bricks withstand varying traffic loads without sinking.
- It helps the landscaping bricks remain intact during rainy seasons and under extreme temperature changes.
Putting a Layer of Sand Bedding Over the Base
After the base has compacted and dried correctly, it’s best to put a layer of sand bedding on top before laying the landscaping bricks.
The sand bedding acts as a waterproof membrane beneath the landscaping bricks, thus strengthening the base further to keep landscaping bricks from sinking in the future.
4. Lay the Landscaping Bricks Properly
The way you lay the landscaping bricks on the base can help keep them from sinking in the future. For best results, it’s best to lay the landscaping bricks properly, meticulously, and methodically.
Here’s how to lay the landscaping bricks properly to keep them from sinking:
- Lay the landscaping bricks in the design and pattern you prefer.
- Lay them tightly together to prevent wide gaps where water may eventually seep through and make the bricks sink.
- Step gently on the newly laid landscaping bricks if you want to reach subsequent rows. Doing so prevents the new bricks from shifting.
5. Sand the Joints of Landscaping Bricks Properly
One of the reasons landscaping bricks sink is because they are not well locked in place. So, to ensure that the landscaping bricks are locked in place properly, fill the joints with fine-grained, wet sand. Fine-grained sand fills up the joints and compacts better than other sand.
Once you seal the joints of the landscaping bricks with sand, water cannot seep through to the base.
If water seeps through the spaces, it could pool, eventually damage the core and cause the landscaping bricks to sink over time.
You could use jointing sand such as Polymeric Sand to seal the joints of the landscaping bricks. Jointing sand is a fine-grained type of sand with a mixture of additive particles (source).
When jointing sand comes into contact with water, it forms a potent binding agent that makes the joints of your landscaping bricks durable.
To complete this step, ensure that the sand and the area dry before people can walk on the landscaping bricks.
6. Use a Joint Stabilizing Sealer
Once the joint sand on the landscaping bricks has dried up completely, applying a joint stabilizing sealer on the newly paved area is a good idea. The benefits of using a joint stabilizing sealer on the freshly installed landscaping bricks include (source):
- The joint stabilizer sealer strengthens and hardens the sand in the joints of the landscaping bricks so that the joint sand doesn’t wear out and disappear.
- It stops vegetation from growing between the joints. If vegetation grows, you will have to pull it out, which could damage the joint sand.
It’s good to first sweep and clean the paved area to remove dust and debris. Also, ensure that the landscaping bricks are dry before applying the joint stabilizing sealer.
7. Install Edge Restraints Around the Landscaping Bricks
When installing landscaping bricks, some people overlook the edges of the paved section.
If the edges of the landscaping bricks don’t lock on all sides, it’s easy for the bricks around the edges to move. Once any landscaping brick moves, water can enter through the gap and spread to the rest of the bricks.
As a result, some of the landscaping bricks may start to sink gradually.
There are different types of edge restraints made of materials such as:
- Precast concrete
Use the one that best suits your landscaping project.
8. Maintain the Landscaping Bricks Regularly
One great way to keep landscaping bricks from sinking is to maintain them regularly. Maintenance of the landscaping bricks may include:
- Inspecting them regularly. It’s best to check the landscaping bricks in your yards once in a while to identify any that may be uneven. If you notice any uneven landscaping brick, sort the issue out immediately before it starts to sink.
- Re-sealing the joints regularly. It’s also good to re-seal the joints of the landscaping bricks with sand regularly to prevent loss of joint sand.
- Using a joint stabilizing sealer regularly. Every time you re-seal the joints of the landscaping bricks with sand, it’s best to use a joint stabilizing sealer afterward. The sealer strengthens the joint sand and keeps it in place.
9. Take Good Care of the Landscaping Bricks
Apart from maintaining the landscaping bricks regularly, it’s good to take care of them. Some things you could do to take care of landscaping bricks to keep them from sinking include:
Removing Excess Water From the Landscaping Bricks
If it’s the wet season, don’t allow water to sit on the landscaping bricks for long. The water can eventually dislodge the joint sand and seep into the ground.
If the water seeps under the landscaping bricks, it could eventually damage the core, and the bricks could start to sink.
Keeping Heavy Objects Away From the Landscaping Bricks
Every structure has limits and tolerances. For instance, if you allow heavy things like machinery to stay on the landscaping bricks for long durations, they could eventually cause some of them to sink.
So, removing heavy objects from your landscaping bricks can prevent sinking and other problems.
10. Hire Professionals To Install the Landscaping Bricks
Poor workmanship is one of the most common reasons why landscaping bricks sink. As mentioned earlier, installing landscaping bricks in your yards is an investment, and you should get your money’s worth.
One way to ensure your landscaping bricks don’t sink is by hiring professionals to install them.
Here are some reasons you should hire professionals to install the landscaping bricks:
- They can give you expert advice: Professional contractors can provide you with expert advice regarding the design for your landscaping bricks project. They can also tell you the best course of action and your options based on their expertise.
- They give you high-quality work: Professional contractors understand the best practices required for landscaping brick projects. So long as you hire a reputable firm, you should expect high-quality work. Your landscaping bricks likely won’t sink when installed by licensed professionals.
Before hiring a contractor, do some due diligence to find their experience and reputation. By doing so, you ensure that you get the best value for your money.
Installing landscaping bricks is an excellent way of beautifying and increasing your property’s value. Landscaping bricks are versatile and can be used to create patios, driveways, walkways, and more.
If you install landscaping bricks correctly, they can last for years.
Some of these tips will help to keep landscaping bricks from sinking:
- Excavate the yard and check the drainage.
- Clear and level the ground properly.
- Create a strong and durable base.
- Install the landscaping bricks properly.
- Install edge restraints around the landscaping bricks.
- Maintain and take care of landscaping bricks.
- Hire professionals to install the landscaping bricks.


Chiefs had announced plans for the Amakhosi Stadium in Krugersdorp as far back as six years ago but its construction will not get underway until all the other building work around the 2010 World Cup preparations are out of the way. Plan to renovate the existing Bob van Reenen stadium in the Mogale City municipality were announced in 2003. It came after a joint agreement between the club, the municipality, the provincial administration and Lefika, a property development company. Bobby Motaung, Chiefs’ football manager and the chairman’s son, is an executive director of Lefika, which has been linked with several controversies around the construction of the World Cup stadium in Nelspruit. The stadium is planned to have a capacity of 55 000 and suites are already for sale on Lefika’s website. But to date no work has begun because the financing had not been raised. The cost was initially estimated at R1,2-billion but has undoubtedly risen since then. Motaung insisted the stadium was going to be built and said a major announcement would be made soon.


Pavement is typically laid at a cross-slope of 2%, or ¼” of fall per horizontal foot of road width measured from the centerline toward the ditch. On unpaved surfaces, the recommended cross-slope is between 4% and 6%, or ½” to ¾” of fall per horizontal foot of width from the centerline toward the ditch.

With plane cross slopes, there is a cross slope break at the crown line and a uniform slope on each side. Curved cross sections usually are parabolic, with a slightly rounded surface at the crown line and increasing cross slope toward the pavement edge.
What is it mean crown of road?
Crown describes the side to side, or the cross-sectional shape of a road surface. Typically road segments are either center-crowned, in-sloped, or out-sloped. The degree of the side slope is typically measured in percent or degrees, or expressed as inches of fall per foot of road width.
What does high crowned road mean?
A high-crowned road is one that is higher at the middle than at the sides. The slope is not difficult to handle if the road is straight or curves to the left. It’s when a high-crowned road curves to the right that a rider can have problems, because it’s like turning on a curve that is banked the wrong way.
What is camber and crown?
Straight Camber or Sloped Camber. This type of camber is provided by meeting two straight surfaces in the crown. Crown is the central and top most point in the surface of the road. The edge shape produces inconvenience to the traffic, so it isn’t used in general.
Why are Michigan roads crowned?
Joints built in to concrete usually allow the road to weather the hot temperatures. But older concrete roads have likely been patched and repaired, as maintenance crews have filled potholes and cracks to keep the roads safe without making a major investment.
Why are roads higher in the middle?
In many countries, these roads are designed in a way that elevates the middle of the road than at the curb due to a number of reasons such as acting as a reminder that the driver is entering a built-up area, safety concerns and drainage purposes.
What is a hilly road?
Thus a road is termed as a hill road if it passes through a terrain with a cross slope of 25% or more and it is characterized by widely differing elevations, deep gorges, a number of watercourses, and steep slopes. The hill roads are also sometimes referred to as ghat roads.
How much crown should a driveway have?
Crown profile: ½ ” of crown per foot of road width from the center. (e.g. 10 ft/2 = 5 ft high point of crown, 5 ft x 1/2” = 2 1/2″ crown height).
What is meant by banked road?
Banking of roads is defined as the phenomenon in which the outer edges are raised for the curved roads above the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn.
What is a flat road?
When a street or road doesn’t go uphill or downhill we say it’s flat or level (I think).
What does grade mean on roads?
Grade is the rate of change of the vertical alignment. Grade affects vehicle speed and vehicle control, particularly for large trucks. The adopted criteria express values for both maximum and minimum grade. The inability to meet either a maximum or minimum value may produce operational or safety problems.
What is a camber road?
Roads are not flat but are designed and constructed to assist in the drainage of water. This is known as a camber. The surface is angled to stop rain water and snow melt gathering into puddles.
What are types of camber?
- Straight Line Camber/ Sloped Camber. Straight Line Camber consists of two slopes originating from the edges and joining at the center of the carriageway.
- Two Straight Line Camber.
- Parabolic Camber (Barrel Camber)
- Composite Camber.
What is camber on a car?
The inward and outward tilt of the tire and wheel assembly (viewed from the front of the vehicle) is called camber. When the top of the tire is leaning inward, it is a negative camber. Positive camber has the top of the tire tilting outward.
Why are Michigan roads grooved?
Transverse grooves across roadways is usually the optimum slip-resistance method, because of the design’s ability to move water off to the side. But MDOT and other states have moved away from transverse tining because of the hum that’s created by rubber meeting the road.
Which country has the fastest construction?
Union minister Nitin Gadkari said on Friday that India holds the world record for fastest road construction. “We made three world records in March. India now holds world record for fastest road construction. We made it to Guinness World Records by building a 2.5 km 4-lane concrete road within 24 hours.
When did the US start paving roads?
One of the first “tar” roads was laid in Paris. The famous Champs-Elysees of the 1600s was covered with asphalt in 1824 signifying it as the first modern road in Europe. By the late 1800s, America would be paving roads. One of the first was Pennsylvania Avenue in Washington D.C.
What is it called when a road splits into two?
The verb bifurcate comes from the Latin word bifurcus, meaning “two-forked.” Bifurcated describes anything that is divided in two: when a road splits into two diverging directions — known as “a fork in the road” — the road is bifurcated.
What is a main road called?
thoroughfare. noun. formal a main road through a place.
What do you call a road that goes up?
“Undulate” is often used for roads that go up and down, while ‘zig-zag’ is used for roads that repeatedly bend to the left and right. The road undulates for three miles before descending into a valley. I enjoy an undulating road while driving, but not while cycling. Copy link CC BY-SA 4.0.
What is the minimum slope of a road?
In general 1 in 200 gradients is sufficient but for cement concrete surface a grade of 1 in 500 is quite sufficient. The 0.5% value may be reduced to 0.30 % for a good quality surface supported on a firm and accurately crowned subgrade.
What is the maximum slope of a road?
In the United States, maximum grade for Federally funded highways is specified in a design table based on terrain and design speeds, with up to 6% generally allowed in mountainous areas and hilly urban areas with exceptions for up to 7% grades on mountainous roads with speed limits below 60 mph (95 km/h).
How do you find the slope of a road?
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.


The objective is to identify the micromechanisms of ductile crack advance, and isolate the key microstructural and material parameters that affect these micromechanisms and fracture toughness of ductile structural materials. Three dimensional, finite element, finite deformation, small scale yielding calculations of mode I crack growth are carried out for ductile material matrix containing two populations of void nucleating particles using an elasto-viscoplastic constitutive framework for progressively cavitating solid. The larger particles or inclusions that result in void nucleation at an early stage are modeled discretely while smaller particles that require large strains to nucleate voids are homogeneously distributed. The size, spacing and volume fraction of inclusions introduce microstructure-based length-scales. In the calculations, ductile crack growth is computed and fracture toughness is characterized. Several features of crack growth behavior and dependence of fracture toughness on microstructural and material parameters observed in experiments, naturally emerge in our calculations. The extent to which the microstructural and material parameters affect the micromechanisms of ductile crack advance and, hence, the macroscopic fracture toughness of the material is discussed. The results presented provide guidelines for microstructural engineering to increase ductile fracture toughness, for example, the results show that for a material with small inclusions, increasing the mean inclusion spacing has a greater effect on fracture toughness than for a material with large inclusions.

Remote Water Monitoring and Expansion
Website / Documentation
An expansion of current water projects to reach more communities so more can have clean water to combat COVID.
Similar to the United States, Uganda is currently on lockdown meaning urban and rural communities can not travel outside their homes. People know clean water is essential to combat COVID-19 and are willing to walk farther to find it. Our different clean water projects are experiencing heightened amounts of pressure because other communities are walking twice as far to collect clean water. We want to develop solutions that will pipe water to their communities to lower the risk of COVID contamination. To better manage our water resources, we also want to develop remote sensoring of water systems to make sure water is being used properly.

A Transportable is literally that – a home that we build on our site before transporting it nearly completed to your property. While we’re in the building process, you take charge of site works and putting in the timber piles for the house to be positioned on. You can check on progress of your home and when it’s ready we deliver it to your site ready to connect to all services.
All that remains to be completed is the plastering and painting of your interior walls and the painting of the exterior walls. This can happen in your own time and saves you money if you’re planning on painting and decorating the house yourself.
Plus, for extra peace of mind the construction of the home is covered by our Master Builders Guarantee.


Renovating Existing Commercial Real Estate Building to Become Green
While green lending is a relatively new and developing form of real estate financing, green loans are available to the owners of new and existing structures alike. In fact, according to Carl Elefante, the former director of sustainable design at Quinn Evans Architects, "the greenest building is one that is already built…Occupying, maintaining, renewing, and adapting existing buildings is the greenest approach." Elefante explained that retrofitting existing buildings not only reduces their energy consumption but prevents the significant emissions produced by construction of a new building. Restoration can consume less than half the energy used on new construction, along with producing significantly less construction waste.
Green loans are accompanied by a number of other benefits to both individual property owners and communities.
In addition to protecting the environment, renovating existing buildings preserves historic architecture, which serves as a cultural, aesthetic and educational legacy for current and future generations.
Green renovation also comes with public health benefits such as improved indoor air quality and reduced exposure to carcinogens and other harmful substances, including volatile organic compounds (VOCs) and plastic by-products, that cause respiratory diseases, allergies and even cancer.
Furthermore, green renovation is a wise economic investment. While initial renovation costs are typically higher than non-sustainable renovations, over time a green property saves more on energy costs, and the value of a green property is considerably higher. Heritage preservation and a historic ambience serve as a popular source of tourism, helping local businesses to attract customers.
How Can Existing Buildings Be Made Green?
In seeking to obtain a green loan, existing buildings may be renovated to employ the use of alternative energy sources that minimize carbon emissions, as described in greater detail in Holland & Knight's previous blog, "Going Green in Commercial Real Estate: Aim for a Zero-Emissions Building Standard" (Feb. 2, 2023).
Historic buildings can also be renovated in other ways to reduce their impact on the environment. These green improvements range from minimal interior updates to major structural renovations. Building owners may install, among plenty of other options:
- a metal roof made of recycled materials with a reflective surface, which reflects the sun's light and prevents heat from entering the home, resulting in a significant reduction in energy costs
- LED lighting, rather than traditional incandescent lighting
- "smart" high-efficiency lighting such as automatic light dimmers and sensor-activated lights that turn on and shut off automatically
- low-flow plumbing fixtures such as low-flow, dual-flush toilets and motion-activated, touch-free faucets
- "smart" automatic shutdown electrical sockets that use sensors or timers to turn off the power in a vacant room or sockets connected to unused devices
- natural, heat-retaining flooring such as concrete and brick that absorbs heat, in turn cooling rooms and reducing the need for air conditioning in the summer
- sustainable flooring such as bamboo that is made from materials that regenerate rapidly or flooring made of reclaimed wood
- insulation in the walls and roof to prevent air leaks and heat loss
- energy-efficient windows designed to prevent the escape of heated and cooled air
- well-planned landscaping to shade, cool (by reducing the amount of heat absorbed by a building) and act as a windbreak, thereby reducing energy bills
- no-VOC paint

Drip Irrigation System
Drip irrigation is a form of irrigation that saves water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. It is chosen instead of surface irrigation for various reasons, often including concern about minimizing evaporation.Drip irrigation is used in farms, commercial greenhouses, and residential gardeners. Drip irrigation is adopted extensively in areas of acute water scarcity and especially for crops and trees such as coconuts, containerized landscape trees, grapes, bananas, pandey, eggplant, citrus, strawberries, sugarcane, cotton, maize, and potatoes.
Advantages Of Drip Irrigation
- Fertilizer and nutrient loss is minimized due to localized application and reduced leaching.
- Water application efficiency is high if managed correctly
- Field levelling is not necessary.
- Fields with irregular shapes are easily accommodated.
- Recycled non-potable water can be safely used.
- Moisture within the root zone can be maintained at field capacity.
- Soil type plays less important role in frequency of irrigation.
- Soil erosion is lessened.
- Weed growth is lessened.
Disadvantages Of Drip Irrigation
- Initial cost can be more than overhead systems.
- If the water is not properly filtered and the equipment not properly maintained, it can result in clogging.
- Drip irrigation might be unsatisfactory if herbicides or top dressed fertilizers need sprinkler irrigation for activation.
- Drip tape causes extra cleanup costs after harvest. Users need to plan for drip tape winding, disposal, recycling or reuse.
- In lighter soils subsurface drip may be unable to wet the soil surface for germination. Requires careful consideration of the installation depth.
- the PVC pipes often suffer from rodent damage, requiring replacement of the entire tube and increasing expenses.
Components and operation Of Drip Irrigation
Components used in drip irrigation (listed in order from water source) include:
- Pump or pressurized water source
- Water filter(s) or filtration systems: sand separator, Fertigation systems (Venturi injector) and chemigation equipment (optional)
- Backwash controller (Backflow prevention device)
- Pressure Control Valve (pressure regulator)
- Distribution lines (main larger diameter pipe, maybe secondary smaller, pipe fittings)
- Hand-operated, electronic, or hydraulic control valves and safety valves
- Smaller diameter polytube (often referred to as “laterals”)
- Poly fittings and accessories (to make connections)
- Emitting devices at plants (emitter or dripper, micro spray head, inline dripper or inline driptube)
In drip irrigation systems, pump and valves may be manually or automatically operated by a controller.

Technology In Construction 2020. The top BIM programming arrangements accessible in 2020 incorporate BIMobject Revit BIMx Navisworks Autodesk BIM 360 and Tekla BIMsight. From wearable tech and roads made out of recycled plastic to connected construction and blockchain read on to learn about the futuristic technologies coming to the construction industry in 2020.
As construction demand continues to grow both at home and abroad companies have to keep up. Top 10 Construction Tech Stories of 2020. As we approach 2020 it is essential to stay current with the construction industrys technology trends.
Here are some examples.
Tesla first unveiled its semi-truck in 2017 which is slated to begin production in 2020. They are advertised as being able to reduce muscle force by up to 60 with a strength amplification of 20 to 1 allowing very heavy objects to be moved with ease. A full-body powered exoskeleton unit. Whilst exoskeleton suits are still in development initial models are expected to be available in early 2020 helping workers carry heavy objects easily.


Please note that following further testing of the new 700mm diameter water main using a non-destructive gas detection technique, a leak has been detected in the pipe at a position just opposite the Holy Trinity Church. This position coincides with a reducer where the 600mm diameter pipe joins the 700mm diameter pipe. It is suspected that one (or both) of the two flexible couplings at this reducer has failed. No other leaks in the main were detected.
In order for Civils2000 to effect this repair it is going to be necessary to operate a short length of Main Road opposite the church under stop/go traffic control conditions. Work will start at 09:00 on Monday, 28 July and unless additional unforeseen repair work is necessary, it is expected that the road will revert back to normal two-way traffic flow conditions by 16:30 that evening. However, if it is found that additional work is necessary, the excavation will be temporarily backfilled for the night and will be re-opened the following day (Tuesday) so that the repair work can be completed that day.


|Boston Public Library Courtyard|
A new addition to the Boston Public Library was opened in December 1971. Philip Johnson observed two specific requests in his design of the new building - to mind the existing roofline, and to use complimentary material to the exterior of the McKim Building. the McKim and Johnson Buildings are connected on three of the Johnson Building's ten levels to provide access to the resources and public services of the library. Unique structural and mechanical systems were developed in order to contain nine floors and a mezzanine level within the high limitations of the neighboring McKim Building.


The City of Kalispell has requested to amend the Kalispell Growth Policy: Plan-It 2035 by including “The Downtown Plan” as a neighborhood plan within the growth policy.
The Downtown Plan sets the framework for the design and redevelopment of Kalispell’s historic downtown and courthouse corridor.
Citizens supports The Downtown Plan to foster the revitalization of the city’s historic core. We believe in rerouting Highway 93 to create a new human-scale streetscape and reduce traffic flow for a pedestrian and bike-friendly area that encourages the growth and sustainability of businesses within the corridor. We believe in keeping the historic character of downtown while preserving it for future generations through smart, high-quality design standards. And we believe in a strong public art program that reflects the creativity and excitement of the city’s heart.
At the August 8th, 2017 Kalispell Planning Board meeting, the board tabled the discussion for a later date TBA. We encourage you to read the Downtown Plan and the other documents under the Links column, then email your own comments to the planning board at email@example.com.

The Andhra Pradesh government on Tuesday rejected claims that a part of the floating bridge that was inaugurated at the beach here on February 25 was washed away, and said it was done as part of a mock drill.
The floating bridge was inaugurated on the port city’s popular R K Beach with much fanfare on Sunday by senior YSRCP leader and Rajya Sabha member Y V Subba Reddy.
However, within 24 hours, images and videos of a broken part of the structure floating in the sea water went viral, which were further amplified by the opposition TDP party, causing major embarrassment to the YSRCP government.
“Due to the high tides, the T shaped viewing point of the bridge has been detached and kept near the anchors to check its stability. But some people clicked pictures of the gap between the bridge and the detached viewing point and alleged that the floating bridge was broken, which is false,” said an official statement from the Visakhapatnam Metropolitan Region Development Authority (VMRDA) on Monday.
VMRDA claimed that the bridge was detached as part of a mock drill, noting that such a separation is a usual technical procedure during strong ocean currents.
Further, it said that it will continue to detach the viewpoint in the future as well, whenever needed as part of mock drills.
Though the government wanted to allow tourists on the bridge from Monday, it prevented them, citing change in weather and strong ocean currents, the release added.
Meanwhile, Industries Minister G Amarnath hit out at TDP, saying it was indulging in fake propaganda over the floating bridge.

Compressed air storage tank construction order:
(1) Installation preparation
(2) Get all equipment in place
(3) Sort out pipe system
(4) Install compressed air pipe flange set
(5) Install subordinate equipment device
(6) Pressure test and cleaning
(7) Anticorrosion treatment
Installation of pressure vessels require professional operation skills, every operation should be strictly following instructions.
Here are details operations for air storage tank installation:
- Preparation work.
Prepare the air compressor and air storage tank, check the bottom of the concrete channel, make sure the channel base is firm and flat. Tie up the equipment with wire rope to move to the hoisting position, hoiste the equipment with 25t crane, and place them in the planned bottom of the concrete position. Fix with expansion screws.
- Compressed air piping system set.
(1) Cut pipe: First of all, mark out the cut position on the pipe according to the site mapping sketch, cut precisely on the marks using grinding wheel or hand saw.
Cut pipe with grinding wheel: put the pipe on the grinding wheel saw pliers and clamp it at the drawing line. When cutting the pipe, the pressure on the handle should be uniform and not excessive. After cutting, iron scraps and burrs on the section of the pipe interfaces should be eradicated and cleaned.
Cut the pipe by hand saw: the pipe should be fixed in the pressure clamp, the saw blade should be aligned with the drawing line, and straight with the axis of the pipe, then push and pull the saw while making sure the force should be uniform and saw to the ends, no twisting or breaking down, otherwise the pipe interface would be distorted.
(2) Welding connection of pipes and fittings: the connection length of pipes and fittings should not be greater than 6 meters, so as to facilitate on-site construction. The groove should be cut before the pipe welding, the mechanical planing method are highly suggested for the groove processing, or choose the oxygen-acetylene flame for cutting, it is necessary to remove the oxide skin surface of the groove, and smooth the uneven surfaces that affect welding quality.
Before pipe welding, the two axes should be aligned. The two pipe ends should be welded firmly on spot.
It is advised to spot weld 3 points on the pipe that below 400mm diameter, and 4 points on the pipe above 150mm diameter.
After welding, it is necessary to check the appearance of the welding seam, and clean the rugged surface,
and splashes if there are any. The welding seam width should not exceed 2mm on each edge of groove.
Bead welding is strictly prohibited. The welding seam shall not have cracks, pores, slag inclusion and other shortcomings. The internal undercut shall not be greater than 0.5mm, and the length shall not be greater than 25mm. For defective welds, it is necessary to completely eradicate the defective parts and weld them from scratch.
When welding the pipe and flange, insert the pipe into the flange, firstly spot welding 2-3 points, and then use the square to find the leveling before welding work, the flange should be double-sided welding, the inner welding seam shall not protruding the flange sealing surface. Flange connection should be close, straight with the center line of the pipe, bolt exposure nut size is not more than half of the bolt diameter.
After the welding of the pipe fittings is finished, the device shall be installed according to the drawings. PTFE pads shall be added between flanges, gaskets shall be added to the bolts on the flanges and 2-3 wires shall be exposed.

 Welcome to the Hoover Dam Bypass Website
 Construction of the Colorado River Bridge is advancing on the 1,060 foot twin-rib concrete arch. The Colorado River Bridge is the central portion of the Hoover Dam Bypass Project. Construction on the nearly 2,000 foot long bridge began in late January 2005 and the completion of the entire Hoover Dam Bypass Project is expected in Late 2010. When completed, this signature bridge will span the Black Canyon (about 1,500 feet south of the Hoover Dam), connecting the Arizona and Nevada Approach highways nearly 900-feet above the Colorado River. Visit the What's New and Construction Activities pages for more details on how this project is advancing. Hoover Dam Bypass Now Open!
The Federal Highway Administration, in conjunction with the Arizona Department of Transportation (ADOT) and the Nevada Department of Transportation (NDOT), officially opened the new segment of US 93, formally known as the Hoover Dam Bypass. Traffic began flowing on Tuesday night, October 19, 2010. Background on the Hoover Dam Bypass Project
 United States Highway 93 (U.S. 93) has been designated a North American Free Trade Agreement (NAFTA) route. The increasing congestion caused by the switchbacks leading to the Hoover Dam site and the restrictions at the dam crossing have led to the development of the Hoover Bypass Project. The Hoover Dam Bypass Project is a 3.5-mile corridor beginning at approximately milepost 2.2 in Clark County, Nevada and crossing the Colorado River approximately 1,500 feet downstream of the Hoover Dam, then terminating in Mohave County, Arizona near milepost 1.7 on U.S. 93.A Project Management Team (PMT) was developed to oversee the design and construction of the project. The PMT has representation from each of the major project stakeholders including the Federal Highway Administration (FHWA), the States of Arizona and Nevada, the Bureau of Reclamation (BOR), the Western Area Power Administration (WAPA) and the National Park Service (NPS). Central Federal Lands Highway Division (CFLHD) will act in the lead management role for all elements of project procurement, design and construction.CFLHD awarded a contract to HDR Engineering, Inc. to provide design and construction support services for the Hoover Bypass Project. An integrated team of professionals from HDR Engineering, T.Y. Lin International, Sverdrup Civil, Inc. and several supporting subconsultants make up the consultant team, collectively known as Hoover Support Team . What's Happening On the Job? The Federal Highway Administration (FHWA) has awarded a $7 million contract to Frehner Construction Company, Inc. of North Las Vegas, Nevada to complete the final roadway elements that will allow traffic onto the Hoover Dam Bypass. This will be the final contract. Work will include completion of signing, striping, median barrier, lighting, paving, and roadway tie-ins at U.S. 93. Additional work will include the paving and parking area improvements for the visitor and pedestrian plaza.The Federal Highway Administration (FHWA) awarded a $7 million roadway surfacing project to Las Vegas Paving Corporation of Las Vegas Nevada in December 2007. The paving project included over 60,000 tons aggregate base, 45,000 tons hot asphalt concrete pavement and nearly 18,000 lineal feet of guardrail. The project is now complete. This project was accelerated in order to finalize paving and guardrail throughout a majority of the Bypass Approach roadways and take advantage of current construction materials prices and minimize any future increases that may result from delays associated with the contractor's crane collapse that occurred during construction of the River Bridge. Advancing this roadway surfacing project ensured continued progress on the Bypass and will have minimized the remaining work to be done after the River Bridge is completed - with the ultimate goal of expediting the final opening of the Bypass.Once the River Bridge nears completion, a final contract will be awarded to pave the short sections of remaining roadway and the roadway tie-ins at U.S. 93, as well as complete final signing, striping, barrier, and pedestrian facilities. It is estimated that this final contract will cost approximately $8 million and will be advertised in late 2009. The total cost to complete the Hoover Dam Bypass remains unchanged at $240 million and is consistent with the original 2001 estimate.The construction contract for the Colorado River Bridge , was awarded to the joint venture partnership ofObayashi Corporation and PSM Construction USA, Inc., in October of 2004 for $114M. Construction began in early 2005 and is expected to be completed in 2010. When completed, the 2,000 foot-long Colorado River Bridge will span the Black Canyon (about 1,500 feet south of the Hoover Dam), connecting the Arizona and Nevada Approach highways nearly 900-feet above the Colorado River. The construction requirements and challenges are as difficult as any in the world.By November 2008, the joint venture contractor had completed over $78M worth of construction. Major milestone work completed included the abutments, approach columns, girders and deck, and arch skewback footings. A number of the arch segments were cast using a temporary form traveler system. The contractor established a new cableway system developed specifically for this project and site. The cable crane system spans the canyon, delivering materials and equipment used in constructing the bridge. Other completed work included the precast segments for the bridge columns which support the roadway on the arch. On August 10, 2009, the arch portion of the Colorado River Bridge was physically connected. Removal of the supporting cable system was completed on August 27th, and the arch is now self supporting and free standing. The bridge is approximately 85% complete.Continued work includes setting the precast columns, erecting the steel girders, and casting of the roadway deck and barriers. (Please see the July/August Project Status Update for more detail on this process. It can be found on our What's New page.) The bridge remains on schedule for completion in late August 2010. Opening of the bypass is on track for November 2010.


This year’s shutdown effort resulted in significant energy savings across many buildings.
Every year, three long administrative holidays – Thanksgiving, Winter and New Year – leave the campus pretty empty. Once the campus clears out, Facilities Management’s Energy Conservation Office (ECO) uses the opportunity to shut off heating systems.
ECO Energy Project Engineer, Sam Cole, puts it this way,
“You wouldn’t leave your home’s heating or cooling systems on while you go on vacation. It would continue to run as scheduled and be an utter energy waste.”
The same would happen on campus as our building’s heating and cooling systems would keep conditioning air for hundreds of empty offices and classrooms.
ECO addresses this energy waste by leveraging the campus’s complex digital building control system to implement new holiday schedules and temperature setpoints for building heating, ventilation and air conditioning (HVAC) systems. The result is more HVAC systems are given a holiday too, and room temperatures are allowed to drift. These holiday savings and setbacks only affect administrative and classroom spaces and exclude laboratory and animal spaces.
The Results Are In
This year’s holiday savings effort resulted in significant energy savings across many buildings. The end results of this coordinated holiday savings effort were impressive:
How much energy is that?
In terms of building energy, we thought of a few helpful comparisons. The amount of energy saved is about equal to:
How did we measure the savings?
The process of accurately measuring energy savings is an evolving practice in the energy industry. Our team followed industry standard methods and guidelines (IPMVP option C, standard R^2 and CvRMSE limits) and adapted them to a larger scale for our campus. The process for quantifying electricity savings can be summarized in the following steps:
Create a building energy model for any building with adequate utility data for heating energy and electricity using Universal Translator 3 ©, and only use models with sufficient accuracy metrics (R^2 and CvRMSE).
Use models to calculate daily savings by comparing actual energy use to predicted energy use during the holiday period.
Extrapolate the daily calculated savings to all shut down buildings, based on total building area.
Create a campus-level energy model for electricity, and calculate campus-level energy savings based on the difference between actual energy use and predicted energy use.
- Compare the extrapolated and campus-level results to ensure result accuracy.
The process for quantifying steam savings was more straightforward, and consisted of only using the campus-level model in Step 4 to quantify total campus savings.
This has been a successful season of energy savings, but there is great potential to help the future success of this tradition grow! There are two main ways this can occur:
Involving more buildings in the shutdown
Shut buildings down during other administrative holidays
Want to be a part of the shutdown?
Our team is diligently working on the tasks above, but we need your help too! We shut down less than a quarter of the core campus’ total building area this last winter. We also only shut down for a quarter of our administrative holidays (think Labor Day, Memorial Day).
By requesting for your space to be shut down during times you know you won’t be in (even on the weekends), we can be even more successful. These requests can be made to your building or space manager, or to the Facilities Management Customer Support Center.


What Home Inspectors Look for During a Roof Inspection
A roof is one of the most important parts of a house as it provides protection from the elements and plays a crucial role in the structural integrity of the building. As a result, it is essential to have a roof inspection done by a professional home inspector before purchasing or selling a property. In this blog, we will discuss what home inspectors look for during a roof inspection.
The first thing that a home inspector will examine during a roof inspection is the type of roofing material used. Different materials have varying lifespans and require different levels of maintenance. Common roofing materials include asphalt shingles, metal roofing, clay tiles, and wood shakes. The inspector will check for any visible signs of damage, wear, and tear, and signs of improper installation.
Roof pitch refers to the steepness of the roof. The steeper the roof, the better it is at shedding water and debris. During a roof inspection, the home inspector will assess the pitch of the roof to ensure that it is adequate for the climate and geographic location. This is important as areas with high rainfall or snowfall require a steeper pitch to prevent water from pooling and causing damage.
Roof flashing is a metal barrier that is installed around chimneys, vents, and other roof penetrations to prevent water from entering the home. The home inspector will inspect the flashing to ensure that it is properly installed and in good condition. Damaged or improperly installed flashing can lead to leaks and water damage.
Roof Gutters and Downspouts
Roof gutters and downspouts are designed to collect and redirect rainwater away from the home's foundation. During a roof inspection, the inspector will check for clogged gutters and downspouts, which can cause water to overflow and damage the roof, walls, and foundation of the home.
Proper roof ventilation is essential for the longevity of the roof and the comfort of the home's occupants. The home inspector will inspect the ventilation system to ensure that it is functioning correctly and that there are no blockages or damage.
Signs of Water Damage
Water damage is one of the most common issues found during a roof inspection. The home inspector will look for signs of water damage, such as stains on the ceiling, mold, and rotting wood. These signs may indicate a leak in the roof or inadequate ventilation.
In conclusion, a roof inspection is an essential part of the home buying and selling process. It provides valuable information about the condition of the roof and can help identify potential issues before they become costly repairs. A professional home inspector will thoroughly examine the roofing material, pitch, flashing, gutters, downspouts, ventilation, and signs of water damage. By identifying any problems, you can make an informed decision about whether to purchase the property or negotiate repairs before closing the deal.


Taupō Airport upgrade flying ahead
Great progress has been made on the Taupō Airport carpark upgrade, with the new seal in place and line marking complete.
Project manager Pernille Fletcher said the next work would be installing street art and lighting to make for a safer environment for those using the carpark in the darker, winter months. Planting would also be carried out in the green spaces around the carpark.
“Stage two of the upgrade will be getting underway from July,” Pernille said. “This will see work begin on the new pick up/drop off area, rental car parks, and the bus zone. Work has also been progressing well on the new terminal building, with the foundation completed and the steel superstructure and timber framing progressing really well.
“Work halted on the project over the busy holiday period to allow for the influx of visitors, but things are now fully back up to speed and it’s great to see the terminal building starting to take shape. We are beginning to get an idea of the scale of the new building, which will be nearly twice as large as the existing terminal, and the more unique aspects of the build that reflect our district will also be taking shape soon. Watch this space, we’ll keep you posted on all the exciting changes.”
With the site work ongoing, airport users are asked to allow extra time when catching flights, and also to use caution around the work site at all times.

There are various types of cement mixer available in the market these days. All these mixers have their unique features and differ in their usage and functionality as well. There are more advanced versions as well as more simplified mixers also. However, which one should a builder opt for, depends upon the requirements of the construction.
Basically the mixers are divided into three broad types. They are two shaft mixers, vertical mixers and drum mixers. The drum mixers are used for production of large volumes of cement. While the two shaft mixers are preferred when the workers require high quality cement in less time. On the other hand the vertical mixers are used when the workers have to deal with colored cement or when they require various discharge outlets for the cement or when small amounts are needed.
The vertical mixers are also termed as Pan or Planetary mixer. This is because of their two main types. The Pan mixers are losing their popularity in the market these days. While the more efficient and quality prone planetary mixers are gaining more momentum. This approval for planetary type vertical mixer is owing to its additional and more advanced features of concrete mixing.
The drum mixers have been dominating the market of ready-mixed cement since a long time. Their high demand has been attribute to their great speed of production. They are also preferable for slump concrete or in situations where the production of concrete as a whole is significant. This type of cement mixer also is easy to maintain and it requires low cost in operating as compare to the other types.
However, all the types of mixers are useful in their own unique ways and serves different demands of the cement buyer population. The three basic types of cement aggregators are being used by the world market at a large rate. This is due to their user friendliness and time efficient results. The ever increasing demand rate for the cement industry has been nowadays matched up with these high quality equipments.
Apart from these cement mixer varieties, there are some special types of trucks that are used to transport concrete. The special attribute in these trucks is that they are made not only to transport the cement but at times of requirement also mix it on the way. These special trucks are called the in-transit mixers.
All the distinct diversity of solid aggregators is very helpful in their exclusive modes and they furthermore assist well the building commerce with their exclusive features. The most broadly utilized diversity of cement mixer is the major three categories. This is because they are not only client amicable but furthermore offer high value outcomes in befitting allowance of time.
These are also utilized when the concrete has to be transported to long distances and therefore a constant mixing is required to prevent the hardening. These concrete trucks along with the various types of cement mixer have given a new dimension to the growing industry of cement. These instruments have made the cement production a lot more standardized and easier task. These cement aggregators also range on a wide spectrum of price but you will have to search around to make sure that you are ending up with a quality product. As a little investment for the sake of quality is a wise decision, indeed.

This is the oldest bridge in Florence: it was first built in the Roman era. Since then it has been damaged and destroyed several times when the Arno has flooded.
After the construction of the "lungarni" – the avenues on the banks – in 1345, the bridge was rebuilt on a design by Fioravanti, with three sections supported by lowered arches, with rows of craftsmen's shops along the sides.
The Corridor was built by Giorgio Vasari, commissioned by Cosimo I de' Medici, to connect the Medici residence with Palazzo Vecchio, where the Grand Duke worked.
The shops were first occupied by butchers, leather tanners and fishmongers, but later Ferdinando I, in 1593, obliged them to be replaced by goldsmiths and jewellers, to stop unpleasant smells rising from beneath the windows of the Corridor.
When Hitler and Mussolini visited Florence in 1939, three panoramic windows were opened half way along the Vasarian Corridor.
It was not by chance that when the Nazis retreated, Ponte Vecchio was the only bridge in Florence to be spared.
The access points to the bridge were damaged, and so the Vasarian Corridor remained the only passage between north and south.
Hotel degli Orafi is located few steps from the Ponte Vecchio and has rooms overlooking the Arno river and the Ponte Vecchio.
The shops on Ponte Vecchio look out onto the central passageway; there are no shops at the centre point of the bridge, to leave space for two panoramic terraces, on one of which there is a monument to the esteemed Florentine goldsmith, Benvenuto Cellini.
