Incredible Hulk is green. Green is power, trees are powerful, nature is powerful. But humans are like the villains, going against true beauty. Polluting the innocent air, chopping down vulnerable trees, throwing our candy wrappers on the ground without thinking. Every negative and positive thing we do impacts the earth.
Buildings have such a big impact on the environment, majority of the impact is negative. The lights and other appliances increase carbon emissions, fumes from the paint enter the atmosphere and add to air pollution. Luckily more green buildings are being built. Green buildings are buildings that are excellent for our environment. They are energy-efficient so they use less electricity, they use materials more wisely and new materials that we wouldn’t normally use such as bamboo wood floors. When a green building is under construction they make sure that waterways remain unpolluted. Lastly, they are great for our health. The air quality indoors is so much better!
Green buildings use very sustainable materials, and are very high-tech. Some of these buildings use skylight tubes, these tubes use a skylight dome on the roof to gather natural light that can be installed anywhere in the building. Recycled glass countertops are also being used in these buildings. Generating concrete has an impact on global warming so the resolution to that problem is to use recycled materials in concrete mixtures.
A building is green when it is LEED certified. LEED stands for Leadership in Energy and Environmental Design. It is a rating system developed by the United States Green Building Council to reward buildings that have good environmental principles.
There is one LEED certified custom built home in Burnaby. The rubber roof has solar panels and provide 15-20% of the yearly electricity used in the home. In the backyard there is a Garden Gourmet compost bin, it handles grass clippings and organic waste. The compost is then used for the soil which benefits the plants. In the kitchen there is an induction stove that boils the water within 45 seconds. Also, there are lot of windows for natural light!
“Going green doesn’t start with doing green acts — it starts with a shift in consciousness. This shift allows you to recognize that with every choice you make, you are voting either for or against the kind of world you wish to see. When you assume this as a way of being, your choices become easier. Using a reusable water bottle, recycling and making conscious daily consumer choices are just a few…” -Ian Somerhalder

Physical phenomenon in which rotating an object exerts a force perpendicular to the wind direction.
By varying the speed of rotation, it flexibly responds to changes in wind speed.
Unlike traditional wind turbines that heavily rely on a singular wind direction for high power generation efficiency, the Magnus wind turbine can generate power regardless of where the wind comes from.
In the event of a disaster that shuts down the power from the grid, Magnus wind turbines can provide power independently as long as the wind continues to blow.
By combining Magnus wind turbines with satellite communications, it can ensure not only power generation but also communications during times of emegency.
It will use renewable energy sources such as solar, wind, and hydro to power our communities in a way that suits the local environment.
By shifting from a centralized to a decentralized system, it is possible to create a community that utilizes sustainable energy without having to transport power from large power plants in distant locations through long power lines.
In addition, electricity can be supplied at low cost even in areas where energy supply costs are high, such as unelectrified areas, and remote islands.

Groundwater hydrogeology, often known as the hydrology of groundwater hydrology, is the study of groundwater. Hydrogeology is the study of how water enters the earth (recharge), flows in the subsurface (via aquifers), and interacts with the soil and rock around it (the geology).
Hydrogeologists put their knowledge to a variety of practical applications. They could:
- Design and build water wells for drinking water, irrigation programs, and other uses.
- Attempt to determine how much water is available to sustain water supplies in such a way that they do not hurt the environment, such as by decreasing natural base flows to rivers and key wetland ecosystems;
- Examine the water’s quality to ensure that it is suitable for its intended application
- They devise plans to clean up polluted groundwater where it exists.
- Design construction-dewatering strategies and deal with mining-related groundwater issues.
- Groundwater-based heat pumps can help to harness geothermal energy.
Knowing about hydrogeology
Hydrogeologists are working to find answers to some of the world’s most pressing issues, such as long-term water supply, food, and energy production, environmental protection, and climate change adaptation. They collaborate with a diverse group of people, including farmers and well owners, as well as other engineers and scientists, agronomists, policymakers, sociologists, planners, economists, and regulators. You can know more about hydrogeology at https://lclenvironnement.com/etudes-hydrogeologiques/.
A hydrogeologist sets out to understand how water moves through a groundwater reservoir after mapping out its dimensions, physical properties, and “plumbing.” Flow measurements at recharge and discharge stations reveal the rates at which water enters and exits the aquifer, as well as the amount of time it takes an average water molecule (the smallest part of water with its properties) to move through the system (residence time.) Water levels and pressures in wells reveal aquifer flow patterns and rates.
Understanding the movement of contaminants
Pollution of groundwater is a possibility. Hydrogeologists can also anticipate how contaminants may enter an aquifer, move through the system, and resurface in a remote spring or well by studying groundwater flow patterns. As toxins travel through an aquifer, an aquifer or soil layer can act as a filter, improving water quality. Others immediately transfer toxic water to a disposal facility. Some rock layers even leach toxic dissolved compounds into the groundwater. Within aquifers, hydrogeologists collect water samples and monitor water quality. They also perform lab and computer experiments to understand the chemical interactions in groundwater better.
Effective management of groundwater resources
To manage groundwater resources effectively, cities and regions that rely on them need precise hydrogeologic maps and a thorough understanding of how water moves through their aquifer. Groundwater is common, public property in many states and countries.
The majority of groundwater consumption and pollution rules and regulations were developed in a period when groundwater systems were little known and thought to be endless sources of clean fresh water.

Automatic train operation system intended for conventional lines that contribute to solution of social challenges
There is growing interest in automatic train operation in the railway industry both in Japan and overseas due to social factors such as threats to the maintenance of railway infrastructure due to a declining birthrate and aging population and the acceleration of population decline. Taking advantage of the safety and reliability technology that we have accumulated over many years, we are taking on the challenge of developing a new automatic train operation system that will support the railways of the future.
Social challenges in the future
- ・ Decrease in labor population engaged in railway service
- ・ Population decrease in areas along railway lines
- ・ Maintenance of railway network including many deficit-ridden local lines
Automatic operation based on ATS
Realizing driverless operation that can ensure safety by unqualified staff without large infrastructure investment
We are aiming to ensure safe train operation by staff who do not possess train operator licenses.
Levels of automatic operation systems for trains are defined according to the GoA (Grades of Automation) standards
This automatic train operation system with GoA level 2.5 will serve as a cushion against the shortage of train operators because it will enable trains to be operated by staff without train operator licenses. In addition, since the system based on the existing ATS (Automatic Train Stop) developed by Nippon Signal does not require the installation of ATC (Automatic Train Control), it can be introduced with minimal infrastructure investment.
Utilizing our accumulated knowledge and market share in the ATS field, we will contribute to the automatization of train operation on lines with ATS, which account for approximately 90% of the railway lines in Japan.
The system developed by Nippon Signal realizes automatic train operation by linking the high-performance ATS-DK with an independently-developed automatic operation calculation unit that is capable of performing advanced train control and can carry out information processing comparable to that of ATC.
Development began in 2018, and in October 2019, the safety function of the system was confirmed on the JR Kyushu Kashii Line. In subsequent test runs starting in December 2019, further efforts were made to improve stopping accuracy, travel time accuracy and ride quality, and finally we achieved automatic operation equivalent to that of licensed train operators. In December 2020, we developed an automatic train operation device (high-performance ATO (FS-ATO)) (*2) based on ATS-DK (*1) and started to conduct demonstration operations on JR Kyushu’s commercial lines.
This was the first time that automatic train operation had been introduced on conventional lines (ATS sections with railroad crossings). The advantage of ATS-based automatic operation is that it can realize an automatic operation system without a large initial investment. Promoting the automatization and mechanization of work is expected to solve social challenges such as the decrease in the working population engaged in railway services. We will aim to realize an automatic operation system that can deliver safe and stable transportation by leveraging knowledge of automatic train operation on the ATS sections of the conventional lines accumulated in the demonstration operations.
*1 ATS-DK: JR Kyushu’s signal protective system. This system controls trains by means of continuous speed checks.
*2 FS-ATO: High-performance automatic train operation device with reliability and fail-safe performance equivalent to a protective device.


In July of 2004 the decision was reached to launch the most spectacular building project in the history of Dr. Ing. h.c. F. Porsche AG. A total of 170 architectural firms from all over Europe had originally vied for the job to build the new museum. Ten of these firms were ultimately invited to formally bid on the job, and the Viennese firm of Delugan Meissl Associated Architects won the bid in February 2005. Actual construction began in October of that year.
At the turn of the year 2006/07, the so-called basement and the core of the building were completed. By that point in time, about 21,000 cubic meters of concrete had been used for the underground garage, ground floor, second floor, and central support beams. The steel structure supporting the exhibition space, which spans 5,600 square meters, was successfully completed in the fall of 2007. The installation of building systems and the interior work began during the same season.
On December 2008, finally, the Museum was handed over to Porsche exactly on time. The opening of the Porsche Museum took place on Saturday 31 January 2009.

What is Roof Flashing?
Roof flashing is a thin, galvanized steel material that roofers use to divert water away from roof areas where the roof plane meets vertical surfaces like walls or dormers. Flashing is used to protect roof features such as skylights, chimneys, vents, and chimneys. The flashing should allow water to flow down the sides and direct it towards the shingles, not the roof deck.
Water could drip from the crevices between the walls and roof if there was no flashing.
Roof leaks are most often caused by damaged or poorly installed flashing. According to the Federal Emergency Management Agency (FEMA), improper roof flashing can lead to wood rot or even deck collapse. If you’ve ever looked at your roof flashing and wondered what it was, there are likely many questions.
What is roof flashing?
Why is roof flashing important?
How do I install roof flashing?
How do I go about repairing roof flashing?
Let’s get started.
There are nearly as many roof flashing types as there are roof parts. Each roof feature requires protection. These are the main types of roof flashing that you should be familiar with:
- Continuous Flashing Because it functions a lot like an apron, continuous flashing is also known as “apron flashing”. It is a single, long piece of metal that carries water to the shingles below. It will be difficult for long pieces of continuous flashing to flex as the home expands or contracts with the seasons. It could crack, warp or fail to keep out water if left alone. Because of this behavior, long pieces are designed to move with your home by having expansion joints.
- Base Flashing: There are some roof features that require two pieces, like chimneys. This ensures that rain falls only to a flashing surface, which directs it downwards. It is also difficult to install flashing around chimneys. Two-part flashing has another advantage: The roof materials can expand and contract naturally, so the entire system remains secure. The bottom flashing, also known as apron flashing, is the bottom-most piece.
- Counter-Flashing: Placed across from or above the base flashing. Counter-flashing completes the system.
- Step-Flashing: Step flashing is a rectangular piece of flashing that has been bent 90 degrees in its center. It’s used for flashing from roof to wall. To ensure water flow away from the wall, multiple pieces of flashing are installed in layers with shingles. Find out how to install it in the below paragraphs.
- Skylight flashing: Although some skylight manufacturers include flashing, roofing professionals may have to make it or buy it separately.
- Valley flashing: Open valleys use metal flashing to protect the roof’s critical areas.
- Drip edges: The roof’s edge has thin metal flashing. This allows water to drip off the roof and not damage the home.
- Kickout flashing: Professional roofing contractors need to be able to connect the gap where step flashing ends with the gutter. Kickout flashing directs water away from the wall into the gutter. Below, learn how to install kickout flashing.
There are many pre-made flashing pieces that you can buy, but roofing professionals can cut their own flashing from sheet metal. They will use tinning scissors to cut the sheets and bend them to their exact dimensions while they are on the roof. Be careful if you go to a shop to purchase your flashing; there are other types of flashing are not designed to be installed on roofs. Head flashing, for example, protects windows and doors from water damage.
Sizes for Roof Flashing
You need to be careful about the size of your roof flashing if you want to repair or install it. Your plumbing vent flashing should be large enough that it can surround the vent. It should not be wider than the vent’s diameter.
Your step flashing pieces must be at least 10 inches long (254 mm), and at most 2 inches (50mm) wider than your exposure to the shingle. 3-tab shingles have an exposure of 5 5/8 inches (143mm). Flashing is usually 10-by-8-inch (253mm x 203mm) in size. These 8 inches will cover most shingles. You can also use the same size to cover longer exposures on Nordic Nordic, shingles.
Roof Flashing Materials
In the past, flashing was made from lead or lead-coated materials by roofing professionals. Dallas roofing professionals prefer to use other materials.
- Aluminium flashing is simple for roofing professionals and lightweight. Aluminum must be coated to avoid reaction with alkaline surfaces. To prevent corrosion, the aluminum flashing should not be used in concrete or masonry areas.
- Copper roof flashing can also be soldered well and is malleable. It is also extremely durable and lasts a long time. However, some homeowners don’t like the patina (a green film) it develops, while others prefer it. Copper flashing will still be found around chimneys.
- Steel is the most popular material for flashing. It is malleable and has aesthetic value. When galvanized, it is also corrosion-resistant.
Your roofing contractor may need to use a particular material for flashing. You may also be required to specify a minimum thickness. Building codes usually require 26-gauge galvanized iron as a minimum. To ensure you are following local codes, it is important to always verify.
If you are in Florida, your building codes may require modified bitumen roofing tape.
- Modified Bitumen Roofing Tape : Modified Bitumen is a tough, water-resistant material. It can be used for roof flashing by being made into tape. Your building code will approve the tape that you use and the minimum width.
Types of Roof Flashing Sealant
You will need to seal your roof flashing with a sealant. Although roofing professionals may use nails for flashing, they will need to decide whether to attach the roof plane or to the vertical wall. The flashing can be damaged by shifting bricks or wood if it is nailed to all of them. The flashing will stay in place if it is attached only to the roof or vertical wall. This allows for the building materials to expand and contract with the seasons.
Roofing concrete: The waterproof seal is created by roofing cement. It is usually applied with a trowel by roofing professionals.
Roof Flashing Techniques
Before you can learn how to install roof flashing, it is important to know that there are three main methods. Each one works for different areas of the roof. There are specific flashing types that correspond with certain techniques.
- Step Flashing: Step flashing is recommended for roof faces that meet walls, such as where a dormer extends from the roof. It is possible for water to flow down the wall, past the shingles, and into the building below. Step flashing makes sure that water does not flow down the wall, but instead ends up in the gutter. It is installed in steps with layers of shingles between so that water flows down each step and into the roof.
- Counter-Flashing: Counter-flashing is used to flash chimneys. There are two types of flashing involved. The base flashing is located around the bottom edge of the chimney. Counter-flashing is embedded in the chimney’s masonry. The counter-flashing is placed over the base flashing so that water doesn’t get behind it. Counter-flashing is used by construction professionals for many other purposes. However, it always requires a second piece flashing that has been set off from the original.
- Plumbing vent boot flashing: Vent flashing consists of a cylindrical piece that fits around the vent. The shingles are placed over the boot or base. Water will run around the vent because of the height of the boot
How to Install Roof Flashing
Disclaimer: Professional roofers should install roof flashing. They are familiar with best practices, safety requirements, and local building codes. These instructions are intended to assist homeowners in understanding what to expect from a professional roofing company.
Step flashing on a roof is the most difficult because it must be done step-by-step just like you are shingling up the roof. Here are some best practices to follow. To cover the flashing, step flashing should be installed first. The flashing must be replaced with siding if this is a repair job. According to the National Roofing Contractors Association, the step flashing must extend 8-14 inches above the shingles.
Before you install your flashing, make sure you check if there is a corner on the roof facing of the wall you are installing.
If it has a corner, please follow the first installation procedure. If the corner is not present and it looks more like the image below then follow the second installation process.
Step Flashing with a Wall Corner: How to Install
You will need to make a corner flashing part if the wall corner is located on the roof. These instructions will show you how to make a corner piece as well as how to install step flashing.
- Step 1: Install the underlayment and your shingles to the point where the wall starts. The corner flashing or the first piece will rest on a single shingle.
- Step 2: To create corner flashing, use your tin-snips to cut a 45-degree line from the outside corner to the center fold. Cut along the center fold, and then remove the triangle. This will allow the step flashing to be bent around the corner. You can purchase pre-bent pieces to make corner flashings, or you can bend a piece of corrugated aluminum.
- Step 3: Turn the corner and flash the light tightly around the corner. Make sure it is flat and at least 8 inches from the shingles. You will need to nail it in place using two nails, one for each side of its top edge.
- Step 4: Get a second piece flashing and place it in its place. Turn it so it covers the corner flashing.
- Step 5: Take out the second piece and apply the sealant to the area where flashing will be visible. Next, place the piece on the ground. Then, hammer one nail into the flashing at the bottom. This will allow the next row to cover it.
- Step Six: Complete a complete shingle course over this piece of flashing.
- Step Seven: You must now apply step flashing to the area where the next set of shingles will begin. The flashing must be at least 3 inches in length. Place the flashing and seal it with sealant.
- Step Eight: Keep switching between flashing and shingles until you reach the top.
- Step Nine: In order to flash the peak of your roof, you’ll need another piece of flashing. Cut a piece of step flashing about halfway into the fold.
- Step Ten: After cutting one side, bend the opposite side to match the peak. This piece can be secured with roofing cement and one nail at the base. Later, you’ll cover it with a ridge shingle.
How to Install Step Flashing where there is no Wall Corner
You don’t need to install a corner flashing piece if your roof face connects with the wall without creating a corner. Kickout flashing is required to guide water into the gutter. Professional roofers may make their kickout flashing in copper by hand, but if you use galvanized steel it will not bend well. You can instead buy a pre-made kickout flashing part.
This is how to install step flashing and kickout.
- Step 1: Install your kickout flashing against the wall at the base of your roof. Take the roofing cement and remove it.
- Step 2: Lay the first piece step flashing on top of the starter strip. Make sure it leads to the kickout flashing. To attach it to the roof deck, use roofing cement and two nails. You will need to place the nails at the base of the step flashing so that you can nail them into the deck. Place the nails high so that the next set of shingles can cover them.
- Step 3: After the kick flashing has been completed, apply a shingle. Apply sealant to the flashing’s base. Apply sealant to the flashing base. The flashing base and nail are covered by the bottom of your shingle.
- Step 4: Complete the whole shingle course.
- Step 5: To finish the step flashing you will need to use the corner piece as described above.
How to Install Counter Flashing on a Chimney
The chimney flashing must be installed while the mason is laying bricks and mortar. Or the roofer will need to create a ridge for counter-flashing. After the flashing is installed, the roofer must seal the inden.
- Step 1: Make sure the chimney’s flashing is in good order. Attach it to the roof according to the manufacturer or mason, and then cover the shingles. You can also install step flashing on the chimney side if you didn’t receive base flashing.
- Step 2: Make a cut in the chimney using a diamond bitsaw/diamond grinding disc. Here is where the counter-flashing will be hung.
- Step 3: Add the counter flashing to the indent. Make sure it is at least 2 inches above the base flashing.
- Step 4: Use roofing cement for the securement of the counter-flashing between the base flashings and the chimney.
- Step 5 : Fill the indentation with roofing caulking so that the counter-flashing hangs securely.
How to Install a Roof Plumbing Flashing Boot
It is usually easier to install a roof plumbing vent than to flash a chimney. This is how it’s done:
- Step 1: Install shingles in the normal way up to the base the plumbing vent.
- Step 2: Install the flashing/boot onto the plumbing vent so that the base rests on the shingles. Apply sealant to secure the flashing.
- Step 3: Push the flashing down to its original position.
- Step 4: Install the next set of shingles. Allow the shingles to cover the flashing at the plumbing vent.
- Step 5: To make space for the vent, cut a circle from the shingles as shown below.
- Step Six: To seal the edge of your shingle, place roofing cement underneath it. Make sure you nail it exactly where you would normally.
You may also need to know how to install other types of roof flashing. Red Ladder Roofing will explain in a future article how to install drip edge flashing and how you can install metal valley flashing.
Is It Possible to Reuse Old Roof Flashing?
It is a good idea to replace all flashing on a typical roof replacement job. The lifespan of a new roof may be cut short by old flashing. There are very limited situations where flashing can be reused by a roofer. If a roofer repairs a relatively new roof, and the flashing looks in good condition, then it might be salvageable.
Your roofer will have to carefully remove your flashing to determine if it can be reused. The flashing will be inspected by your roofer before being reused. Your roofer will need to remove the flashing if he is installing shingles around it.
Step flashing is a more difficult type of flashing to reuse as it can be harder to separate the old shingles from it without causing damage. A roofer will typically replace step flashing on new roofs.
Your roofer should not add flashing to the existing flashing. A roof should have only one layer of flashing.
When You Should Fix a Roof Flashing Leak
It is possible that you are curious about what flashing has been damaged and when it should go to be replaced. You can check your flashing for the following:
- Holes, bending, or other obvious physical damage.
- Corrosion and rusting.
- Missing or loose nails.
- Missing or dried out sealant.
- Flashing that is loose.
You may have to replace flashing if you notice any of these issues.
It’s possible that you will need to replace the flashing during a roof installation. It depends on several factors. It is possible to reuse original flashing if it is in good condition and can be taken out without damaging it. If you want a waterproof roof, it is important to put your money into proper fit and seal.
How to Repair Roof Flashing
Roof flashing is best left to professionals. Your roof is too important to risk damage during a self-install.
- Step 1: Gently lift up any shingles that are covering or surrounding the flashing. This may also involve removing damaged flashing pieces.
- Step 2: Use your chisel to gently remove any asphalt cement that you find.
- Step 3: If the flashing problem was caught before the leak started, the roof structure and parts should not be damaged. It is important to inspect for any damage. You will need to repair any damage before you reinstall the flashing.
- Step 4: Now, install the flashing and shingles again. To ensure flashing is water-resistant, make sure you follow the instructions as described above.
Roof flashing may not be the most striking element of a roof but it is the most crucial. We recommend that you contact Red Ladder Roofing if you notice flashing problems on your roof. Professionals can solve your flashing issues and answer any questions about your particular roof.


Changi Airport's Terminal 1 car park to close in 4th quarter of 2014
Changi Airport's Terminal 1 car park which consisted of 850 open-air lots will be closed for construction of Changi’s Project Jewel complex.
The Jewel complex will have a total gross floor area of 134,000 sq m and cost about $1.47 billion to build. 70% of the complex will be retail shopping with an underground car park of 2,500 lots. The complex will also link up terminal 1, 2 and 3 and Changi Airport MRT station.
The construction is expected to be done by 2018 and in the meanwhile, drivers heading to terminal 1 will have to park their vehicle at terminal 2 carpark.
As there is a significant decrease in parking space due to the construction, the parking fee will be made more expensive if drivers plan to park their cars at the airport for extended period of time.
The initial $20 parking cap will be removed and drivers will need to pay up to $60 for a day worth of parking.


When it comes to surface finishes for timber, rough sawn timber is the most popular for discreet applications for a number of reasons. Not only is it aesthetically the most rustic and raw of all timbers, but it is also the most cost effective timber to use. The manufacturing process of this timber is more sustainable than some others, and results in efficiency. It is simply cut from the saw, and then it is ready to go. At this stage it can be painted, if desired– without requiring any further treatment. If you look for it, you will easily find that rough sawn timber is used in some discreet applications, the two most common of which we have put together in this article for you.
Timber beams are usually used in the building of houses to provide large support points for the framing and construction. Though steel is a traditional and common way of crafting these beams, timber is becoming more and more popular for a wide variety of reasons, including the fact that it is cheaper and less prone to world fluctuations in prices, and builders only need one supplier or fabricator for all the homes structural need. To top it off, timber is lighter and requires simpler handling procedures.
Rectangular Timber Sections
Rough sawn timber is great for rectangular timber sections, as it offers the durability and canvas required for such an application.
Finally, you will find rough sawn timber used in some places where aesthetics and dressing is not a requirement. When these requirements begin to increase, rougher header and dressed timber become more suitable for the job.
If you are after some sawn timber, or any other form of timber for that matter, get in touch with the experienced team at Australian Treated Pine. With over 30 years’ experience in the industry, they are masters in the field.

The Brandon Recreational department has received a recreational facility grant of $10,000 for the park on Seminary Hill. The grant will help fund construction that will provide ADA access to the park and will help with other improvements.
“We want to make a safe walk-able park, which will house a donated McDonald’s play structure,” said Rec. director Bill Moore at the Brandon Selectboard meeting on Monday, Sept. 23. “We are looking at a construction date of early summer of next year.”
Town Manager Dave Atherton updated the board on the Segment 6 construction in the town as well.
“They have been putting down a lot of pavement recently,” Atherton said. “Sidewalks are being poured and they are starting to demobilize some equipment.”
Atherton also said that crews would be starting to set curbs again soon.

Aurora Power Consulting was contracted by Welsh Power to carry out a detailed earthing study for a new synchronous condenser site connected to the 400kV transmission network in Scotland, UK. Auroras scope was to carry out a detailed earthing study and prepare an earthing layout to assess the Earth Potential Rise (EPR) and associated touch and step voltages for local system faults and transferred potential from the upstream grid substation in accordance with ENA 41-24 and ENA S34.
The first step in the process was to arrange for a series of soil resistivity surveys to be carried out for each area, using the Wenner method. The results of the Wenner test were then used to produce a representative soil model of the site, which allows the initial earthing layout to be carried out. A detailed simulation was then carried out to determine the fault current return split factors and transfer voltages in PSCAD, and then using CDEGS to determine the EPR and associated touch and step voltages on the system for various fault conditions, before refining the earthing system to ensure that all voltages were within tolerable limits.

Many building and other companies hire the scaffolding they need to get their projects done rather than buy the materials and erect it themselves. This is because scaffolding is really in a genre of its own and needs professionals to design and erect it, especially when it is for building skyscrapers or other huge projects. If you are seeking a scaffold hire company, here are six points to consider: –
- Does the scaffold hire company have a good reputation in the industry? You will be able to find out by contacting other building companies that have used them. You can also look at their website to see which other companies have used them or to look for testimonials. A good reputation is not only about providing quality products, but also about being on time and within budget. If the scaffolding is late going up, your project completion will be delayed
- Does the company employ engineering professionals to design the kind of scaffolding that you will need? Generic scaffolding may not suit your project. If you need a special design, you will need an engineer to design it to ensure strength and stability.
- Can the company also supply labour to erect the scaffold? Erecting scaffold is a job for highly trained professionals. There should at the very least be some kind of training for your own employees if they have to erect it. However, in many cases it is far more cost effective to use a company that provides labour and also other specialist staff for overseeing the task or for other work such as crane driving.
- Does the cost of the scaffold include dismantling it as well as erecting it? Will they replace faulty scaffolding? You also need to see a breakdown of costs so that you know just what you are paying for.
- Does the scaffold suit the purpose it is intended for? There are many different materials and types of scaffolding. Some are meant for lighter, low work, while others are meant for heavy duty, high-rise work. Find out what specifications are needed for your project and make sure the right one is delivered to ensure maximum safety.
- Competitive pricing. Check out a few different scaffold hire companies to find out what the going rate is. Naturally you want competitive prices, but you may not find that the cheapest one is the best. Find out about their quality and the services they offer before making a decision. It could be that a mid-range price offers more value.
Once you have ticked all the boxes of your requirements for hiring scaffold, you can be sure that what you get is exactly what you need. Your project can then go ahead within the right time frame and budget.


A commercial energy rating involves an analysis of a building construction plans and onsite inspections. Based on the buildings plans, the Commercial Energy Rater uses an energy efficiency software package to perform an energy analysis of the Building's design. This analysis yields a projected, pre-construction Index.
Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the building will meet performance guidelines. The rater then conducts onsite inspections, typically including a blower door test (to test the leakiness of the building) and a duct test (to test the leakiness of the ducts). Results of these tests, along with inputs derived from the plan review, are used to generate the Index for the building.


Tired of using a temporary "Blue roof" while you wait for roofing repairs? What if you could install a stronger roof that would withstand higher winds? Leave it to the experts at New Orleans Roofing & Siding to provide you with an ideal solution.
Let's face it. With hurricane season just around the corner, now is the perfect time for New Orleans residents to consider replacing their old asphalt shingle roof. With a variety of colors available and a lifetime manufacturer's warranty, steel roofing systems are sure to outlast any ordinary roof - on average three times longer.
Understanding Wind Rating Zones and Your Roof's Capabilities
While most asphalt roofs installed in the United States only provide a wind rating up to 90mph1, metal roofing has a 140-mph wind rating, meaning it can withstand wind gusts up to 140 miles per hour.2 When choosing your roofing materials, it is important that your contractor follow the Basic Wind Speeds implemented by IRC and adopted by the Louisiana State Uniform Construction Code Council(LSUCCC)3 to ensure your roof can withstand the elements. In southern Louisiana the wind rating zones range from 100mph and upward, with the metro New Orleans region falling in the 110-120mph zone. Any asphalt roof with a 90mph rating will simply not hold up in these potential wind conditions.
If you're ready to make the transition to a steel roof that will last a lifetime and would like more information, simply fill out the form on this page entitled "Get Your Price Now," and a representative will be glad to assist you.

Rock reamer hole opener, also known as trenchless technology, has been widely used in recent years.
Choose the rock reamer hole opener according to the type of traversed stratum, which is an important factor in selecting the size and type of the rock reamer hole opener. When expanding holes in soft rock formations, larger diameter expanders and fewer hole expansion times are allowed, and the size difference between adjacent stages of expanders can also be larger, with a difference of 100-150mm. When expanding holes in hard rock formations, the required diameter changes of the hole expander cannot be too large, with a difference of 50-100mm, and multiple hole expansions are adopted to achieve the best hole expansion efficiency and smooth discharge of drill cuttings.
Horizontal directional drilling is a high-risk industry, and accidents can occur at any time with a little carelessness. In order to meet the needs of replacing the hole expander or releasing stuck drills during a single hole expansion, the design of the rock reamer hole opener should also consider the function of reverse withdrawal of the drill hole. The main purpose of hole expansion is to remove the drill cuttings in the borehole, not just cut them down. Therefore, when selecting a hole expander, we hope that the generated drill cuttings are small enough to suspend the drill cuttings in mud and smoothly discharge them to the surface.
The rock reamer hole opener may encounter a series of problems after a period of use, such as inability to operate properly and various problems that occur during operation, which may result in the need to terminate the operation midway and affect business processes and performance. So why do these problems occur and how can we solve them?
First, let's explain why the rock reamer hole opener may encounter a series of problems after a period of use.
For example, if it cannot operate properly and problems occur after a short period of use, the first possibility is that it was not operated according to the operating procedures for the rock reamer hole opener's encounter with a series of problems after a period of use. There may be no regular lubrication, or inappropriate lubrication at the wrong time in a dry environment.
It is necessary to operate according to the operating procedures, perform regular and targeted lubrication for the rock reamer hole opener at the designated time and location, keep the rock reamer hole opener clean, and timely replace severely worn parts.

Ohio Department of Transportation (ODOT) Director Dr. Jack Marchbanks announced last week that ODOT will invest $51 million into new traffic safety improvement projects to specifically address an increase in pedestrian-involved traffic crashes and fatal roadway departures on state and local roads.
The City of Bowling Green’s Highway Safety Improvement Program application was selected for funding, securing $1.2 million for a shared use path to connect the Community Center with the Bowling Green High School and Cogan’s Crossing, functioning as a link to residential roads and neighborhoods. A shared use path provides a travel area separate from motorized traffic for bicyclists, pedestrians, skaters, wheelchair users, joggers, and other users. The 10-foot wide shared use path will further the City’s complete streets efforts and will build infrastructure identified as a route on both TMACOG’s 2045 On the Move Update and the designated U.S. Bike Route 25 through Bowling Green.
ODOT will release the funding to the City over the next three years, covering 90% of the cost of this project. The phases of the project will include design, right-of-way acquisition, and construction. The goal is to have the project completed by the end of 2026.

Fiber cement siding can successfully masquerade as wood or masonry at a much lower price point. This is the only siding that combines the performance of masonry: minimal maintenance, is rot, fire, and termite-proof, and is unaffected by extreme temperatures. Designers and architects recommend fiber cement siding since it is an affordable option and it’s even accepted for some historic districts.
Weather and Fire Resistant
While wood siding is susceptible to moisture and harsh weather conditions and tends to expand and peel over time, fiber cement siding has been engineered based on climate research. It is extremely durable and withstands extremes of both hot and cold temperature changes. It is impervious to strong UV radiation at high altitudes and doesn’t become brittle in cold or below-zero temperatures. Fiber cement siding is specifically designed to withstand the demands of your particular climate. James Hardie siding Denver will not ignite when exposed to flame or melt like traditional vinyl siding. In locations that are vulnerable to wildfires, some insurance companies offer a discount for homes sided in fiber cement since it is non-combustible.
Fiber cement siding is a certifiable green product made from sustainable materials such as wood pulp (wood waste that would otherwise be discarded) and cement. The making of fiber cement siding doesn’t require the use of fossil fuels like vinyl siding and it makes an affordable option for eco-conscious buyers.
Curb Appeal and Resale Value
Because fiber cement looks so natural, it can elevate the curb appeal of a home. A reason for the returns found in fiber cement siding replacement is the ability to enhance the curb appeal as first impressions about the exterior of a home can make a significant impact on a potential buyer. Fiber cement siding can easily be painted in versatile ways to make your home stand out if it’s on the market. James Hardie is a leading manufacturer of fiber cement siding and has been ranked by with the highest return on investment by Remodeler Magazine’s 2017 Cost vs. Value Report.

Originally hatched in Europe, Mobility as a Service (MaaS) is a concept of integrating private and public transportation from bike sharing to the bus to the train through a unified payment service.
“MaaS is a theme that affects transportation infrastructure, requiring investors to think beyond a traditional linear value chain, to understand how their assets can provide utility as part of a more integrated system,” QIC’s head of global infrastructure Ross Israel says.
QIC says MaaS is the “the greatest transformation of the mobility ecosystem since the invention of the motorcar” and calls on infrastructure investors to remain diligent with respect to their future acquisitions and actively manage their existing infrastructure assets to capitalise on the range of opportunities.
For infrastructure investors, “the strategy is to leverage information to draw demand to existing assets, increase patronage and thereby deferring capital expenditure on new assets.”
Existing infrastructure concessions – such as toll roads, car parks and metros – will serve as anchors, resulting in the various forms of transport becoming more integrated into a single MaaS, accessible on demand, according to Israel.
“The concept would be embedded in airports: car parks would be integrated with passenger drop-off and car fleet management, with tailored bus services as well as share riding.”
One motivation would simply be to respond to customers. In a survey conducted by Newgate Research as part of the University of Sydney’s Better Infrastructure Initiative, a third of respondents viewed road operators as customer-focused but 90% considered ride-sharing companies to be customer-focused.
QIC, which has owned 25% of the concession to operate Brisbane Airport since 2007, sees it in the simplest term: “it’s about finding the quickest way to get out of the airport,” says Israel.
On the other side of the world, QIC – which has 50-year concession to operate Ohio State University’s car parks – is piloting a programme to integrate buses and share riding.
More broadly, the widespread adoption of MaaS will require a diverse range of actors to cooperate, from mobility management players, telecoms operators, payment processors, public and private transportation providers, as well as local governments with responsibility for transportation and city planning.
Ultimately, the local governments will be responsible for setting up an integrated transportation planning system with a simple centralised payment system.
“Helsinki has set the blueprint – the aim is that by 2025, the city plans to make it unnecessary for any resident to own a private car,” says Israel.
Helsinki residents have been able to use an app called Whim since 2016 – to plan and pay for all modes of public and private transportation within the city, whether by train, taxi, bus, car share or bike share.
The Finnish capital is not alone, however. Paris, Eindhoven, Gothenburg, Montpellier, Vienna, Hanover, Las Vegas, Los Angeles, Denver, Singapore and Barcelona have all piloted local versions that span the spectrum from modest peer-to-peer (P2P) offerings to integrated public transportation to combined mobility services that include both public and private sector players, according to QIC.
All of which will hinge on data. “The key is to coordinate data – from the bike ride to the car to the rail to ferry,” says Israel.
To that end, “rolling out the next generation of 4G/5G will be critical because most travel arrangements and cashless payments will be made through mobile devices requiring high levels of connectivity,” he said.


What is the difference between erosion and mass movement? Definition: Erosion is the dislodging of sediments that initiates their movement. Particles may then be moved away by sediment transport agents such as wind, water, glaciers, etc. Mass movement refers to earth materials moving downslope under the influence of gravity, as in rockslides, mudflows, slumps, etc.
Which mass movement is the fastest?
Landslides and avalanches can move as fast as 200 to 300 km/hour. Figure 3. (a) Landslides are called rock slides by geologists.
Can trigger a sudden mass movement?
A mass movement can occur any time a slope becomes unstable. Sometimes, as in the case of creep or solifluction, the slope is unstable all of the time and the process is continuous. … Shocks and vibrations – A sudden shock, such as an earthquake may trigger slope instability.
Where is soil erosion currently the most severe?
The majority of Caribbean countries, Brazil, Central African countries, and parts of Southeast Asia are experiencing severe erosion on more than 70% of their arable land. In contrast, Australia, Canada, Saharan countries, Russia, and most of the European Union are only losing 3% of their arable land to severe erosion.
How do humans can contribute to mass wasting?
Humans can contribute to mass wasting in a few different ways: Excavation of slope or its toe. Loading of slope or its crest. Drawdown (of reservoirs)
What is the slowest mass wasting process?
The slowest and least noticeable, but most widespread of the slow mass wasting categories is creep. Creep involves the entire hillside, and is characterized by very slow movement of soil or rock material over a period of several years.
What type of mass movement is the slowest fastest?
Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements. The only way to detect soil creep is to observe the fences, buildings, and other surface objects that may be in that area.
What are 4 types of mass movement?
There are four different types of mass movement:
- Rockfall. Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
- Mudflow. Saturated soil (soil filled with water) flows down a slope.
- Landslide. Large blocks of rock slide downhill.
- Rotational slip. Saturated soil slumps down a curved surface.
What causes a debris flow?
Debris flows can be triggered in a number of ways. Typically, they result from sudden rainfall, where water begins to wash material from a slope, or when water removed material from a freshly burned stretch of land. … Another major cause of debris flows is the erosion of steams and riverbanks.
What is the most important factor in causing mass movements?
Gravity: the most important factor in causing mass movements. Water: adds weight to the slopes and reduces friction between the soil particles.
What is the difference between an Earthflow and a debris flow?
A debris flow is the movement of a water-laden mass of loose mud, sand, soil, rock and debris down a slope. … An earthflow is a flow of fine-grained material that typically develops at the lower end of a slope. Earthflows often ooze down a mountain at a pace of a slow-moving earthworm.
What state has the most soil erosion?
Many soils in the area are highly erodible, and erosion is appreciably higher than the national average. * The Corn Belt States experience some of the highest erosion rates in the country: in 1977, Iowa cropland lost an average of 9.9 tons of soil per acre; Illinois, 6.7 tons per acre, and Missouri, 10 9 tons per acre.
How serious is soil erosion in the United States?
Soil erosion on agricultural land in the United States does not pose an immedi- ate threat to the Nation’s ability to produce food and fiber. However, erosion is impairing long-term soil productivity in some areas and is the largest contribu- tor to nonpoint source pollution of the Nation’s waterways.
Why is poor quality soil a problem?
Soil degradation leads directly to water pollution by sediments and attached agricultural chemicals from eroded fields. Soil degradation indirectly causes water pollution by increasing the erosive power of runoff and by reducing the soil’s ability to hold or immobilize nutrients and pesticides.
What are the negative effects of mass wasting?
Mass movements affect the following elements of the environment: (1) the topography of the earth’s surface, particularly the morphologies of mountain and valley systems, both on the continents and on the ocean floors; (2) the character/quality of rivers and streams and groundwater flow; (3) the forests that cover much …
How can we prevent mass wasting?
Engineering solutions include barriers and retaining walls, drainage pipes, terracing the slope to reduce the steepness of the cuts, and immediate revegetation. Rockfalls can be controlled or eliminated by the use of rock bolts, cables, and screens and by cutting back slopes to lesser gradients.
Which change can lead to slope failure?
Which change can lead to slope failure? the shearing stress on the material exceeds its frictional resistance (or shear strength) .
What triggers mass-wasting?
Mass-wasting events are triggered by changes that oversteepen slope angles and weaken slope stability, such as rapid snow melt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, stream erosion, and human activities. Excessive precipitation is the most common trigger.
Where is the largest landslide located?
In 1980, the explosion of Mount St. Helens in the state of Washington, United States, triggered the largest (on land) landslide ever recorded. Mount St. Helens is a stratovolcano situated in the Cascade Mountains, 88 kilometers northeast of Portland.
What are 2 examples of mass movement?
Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting.
What is fall in mass movement?
The basic types of landslide movement are: Fall. This is generally characterized by rapid or extremely rapid rate of movement with the descent of material characterized by a freefall period. Falls are commonly triggered by earthquakes or erosion processes.
How do you survive a debris flow?
You can’t stop or change the path of a debris flow. However, you may be able to protect your property from floodwaters or mud by use of sandbags, retaining walls or k-rails (Jersey barriers). In mud and debris flow areas, consider building channels or deflection walls to try to direct the flow around buildings.
What is the difference between a debris slide and a debris flow?
Debris flows differ from slides because they are made up of « loose » particles that move independently within the flow. A slide is a coherent block of material that « slides » over a failure surface. … Debris flows have larger particles – at least 50% of a debris flow is made up of sand-size or larger particles.
How fast does a debris flow move?
Debris flows can travel at speeds up to and exceeding 35 mph and can carry large items such as boulders, trees, and cars. If a debris flows enters a steep stream channel, they can travel for several miles, impacting areas unaware of the hazard.

The Grove is pursuing LEED for Homes certification, which is a green home certification program for homes that are designed and built to be energy- and resource efficient and more healthy and durable for the occupants. LEED-certified homes complete a technically rigorous process that often includes a home energy (HERS) rating and onsite inspections to verify that the home is built to be energy and water efficient, environmentally sound, and a healthier place to live.
These apartments set the example that we can all live better by reducing our environmental footprint, cutting our utility bills, and coming home to a greener place to live.
Located in Rexburg, The Grove is within walking distance of public transportation, shops and other conveniences. The design and construction team is focusing heavily on reducing energy use. This 48-unit project features high efficiency windows and lighting and high density, recycled cellulose insulation that blankets the building. Other energy efficiency upgrades include instantaneous water heaters, programmable thermostats, pipe insulation and high efficiency gas furnaces. These features not only reduce future utility costs but also result in a more comfortable home.
Water conservation is a priority with high efficiency irrigation and plumbing fixtures, drought tolerant plants and minimal turf.
Special attention is being paid to using healthy materials with low emissions. Non-toxic, zero-VOC (volatile organic compounds) paint, Green Label Plus certified carpet and low-VOC adhesives and sealants are being used to protect the indoor air quality for construction workers and residents. In addition, continuous ventilation in the units will ensure fresh air and mitigate against mold. EPA approved, radon-resistant construction techniques are being utilized to protect residents from the risk of radon, the second leading cause of lung cancer.
Local lumber and cement from Idaho and recycled wood moldings and doors protect the environment and support local economy. The team is targeting a reduction in construction waste of over 60% by recycling and diverting wood, plastic, glass and metal from the landfill.
As a result of incorporating energy saving products and technologies, The Grove is estimating a 65 Home Energy Rating System score (on a 100 point scale with 0 being a net zero home and 100 being a home built to code). Think of this as a “MPG” rating of your home.
We are proud to be pursuing LEED for Homes certification and look forward to becoming one of over 55,000 other homes to be certified in the U.S.


If you’re a city dweller who wants a property within the suburbs, it’s probably that you’re checking out homes with septic the first time. This situation has a tendency to make buyers nervous. It needn’t.
Let’s take an overview of exactly what a easy septic system is, how it’s taken care of, and what you can do if you’re investing in a home which uses one. A septic system is a personal-included system for disposing of sewerage. They’re frequently found in outlying and suburban locations that do not have public sewerage systems. The system one sees generally is a holding tank in which enzyme and bacterial motion decomposes the waste material and buried outlines inside a drainage field use garden soil to stress out what continues to be.
Septic allows are often released specifying the quantity of bed rooms a home might have that is going to be constructed around the great deal for which the allow will be issued. How good the garden soil percolates (how good water drain pipes through the soil) on the lot is taken into consideration when issuing the allow. It usually expenses between $6,000 and $10,000 to set up a conventional system in the part of the country I live in. Techniques are often sufficient for the size of the house due to the allow system.
Each time a system and the demands of the home will be in balance, it may be literally years between occasions any maintenance is necessary. Some jurisdictions require they be motivated periodically. There are companies which make a specialty of this. In my area it expenses about $200 to get a septic tank pumped.
Home Buyer Precautions
There are a variety of things a homebuyer can perform when buying a property using a septic system to lower the possibility of possessing a problem. You could make your contract provide subject to a septic inspection and working. It is possible to ask the owner to sign an affidavit saying that to the best of his knowledge the allow was issued for the number of bed rooms your home has, or, additionally, you can check on the courthouse yourself. Just contact and get what department handles the permits, then call that division and get about archived information.
Water should not stand for hours after a weighty rain on property with a septic system. There will not be any unpleasant smell associated with septic system.
What we’ve been talking about is a easy conventional septic tank and deplete area. It was once practically extremely hard to install a septic system in which the soil will not deplete well, or where water table is higher. Clay soils don’t deplete well. Higher water tables are often experienced near the ocean, near marshy areas, and in areas near big body of water. Some pretty amazing techniques which could handle problem areas have been developed lately.
I was recently talking to a contractor friend of my own who may be building a new house for his very own family members. The garden soil on their own property drain pipes very poorly. They have completed some investigation and contains contracted out getting an option system installed. He got three bids which ranged from $18,000 to $60,000. After speaking with the producer, he accepted the reduced bid. It appears such as the finished wvvdya will come in right at $20,000 as well as the contractor is following the procedure recommended through the manufacturer.
I’ve observed very few re-sales of qualities utilizing these extremely-duper techniques-on-steroids, but I forecast they’ll begin turning up relatively quickly. My contractor buddy states he could build a house on a rock and roll making use of the best new techniques. It appears like we have now some interesting developments to look ahead to, doesn’t it?
