Los Angeles is seeing the effects of statewide green building codes on architecture and development in the downtown area.
With around 2,000 green buildings and counting, Los Angeles has distinguished itself as one of the most progressive cities in the country for green development.
“I think right now L.A. has really been leading the charge, and a lot of the changes we’re seeing through CALGreen on the state level are coming through some of the things the city of L.A. has really been pushing,” said Anthony Brower, Director of Sustainable Design at the Los Angeles office of Gensler, a global design firm.
Standards such as the California Green Building Standards Code, or CALGreen, have set a benchmark for energy and water efficiency, planning and design, environmental quality and material conservation for building construction in California.
CALGreen was the nation’s first statewide green building code and was developed to improve public and environmental health by encouraging sustainable construction practices with low environmental impacts.
“There’s a lot of basic prescriptive requirements that are expected to be dropped in to every single new building, alteration or interior renovation that’s going on in the state,” said Brower. “Each municipality can either choose to just accept that as a starting point and go with it, or they can add their own requirements on top of that or make some of those basic requirements a little more stringent.”
Los Angeles’ mild climate and terrain is well suited for a minimalistic architectural style, but decades of reckless development has left unsustainable, poorly planned architecture scattered throughout the city. By incorporating environmental morals and green building codes, architects are approaching development in Los Angeles in a holistic approach.
“The thing is green building and good design are the same thing,” said Nicos Katsellis, Associate Project Manager at the Los Angeles office of Leo A Daly, one of the largest planning, architecture, engineering, interior design and program management firms in the world. “That’s not a recent philosophy, that is something that has been practiced for eons over different cultures—organic, sustainable architecture usually works with the environment and those are principles that guide architecture universally.”
The Los Angeles chapter of the U.S. Green Building Council, or USGBC, provides resources, networking and recognition for green building throughout L.A. County. The USGBC has developed LEED, Leadership in Energy and Environmental Design, one of the most successful international green building third-party verification systems.
“It’s a rating system that quantifies by points how green a building is,” said Dominique Smith, Interim Executive Director at the Los Angeles chapter of the USGBC. “LEED allows you to compare buildings of a similar type, and say which one is green and which one is not.”
Architects, developers and building owners aim to certify their buildings through LEED to establish credibility on an international scale. LEED addresses categories such as water efficiency, energy and atmosphere, materials and resources, sustainable sites and indoor environmental quality when rating a building. Los Angeles currently has around 2,000 LEED certified buildings.
“We see Los Angeles as possibly becoming one of the largest green cities in the nation,” said Smith. “We look at San Francisco, Chicago, New York and we realize that with the number of buildings and the number of people that we have here in Los Angeles and the fact that our geography is so spread out, we have a lot of work to do, but we’re doing the work right now in laying the foundation for a very green Los Angeles.”
The Los Angeles office of Leo A Daly has not certified any building less than LEED Silver in the last 5 years.
“It’s not just basic certification, you want to go above and beyond and maximize the sustainable strategies because all-in-all it creates a better product, service, and a better relationship with the client,” said Katsellis.
By incorporating LEED and CALGreen principles in a building’s design, it is not only more environmentally sustainable, but it becomes more economical as well.
“A lot of developers are finding out that sustainable buildings make sense where it matters, and that’s the wallet,” said Katsellis. “They’re more economic, and the return of investment definitely contributes to the selection of sustainable strategies.”
Since it is infeasible to demolish and rebuild every non-green building in downtown L.A., the Los Angeles office of the USGBC is targeting class B and C buildings for green retrofits.
Class B buildings are usually older, but are still functional and have acceptable quality management. Class C buildings are generally older than 20 years, outdated, and in poor areas.
“We’re working with several other different organizations right now to identify those because they could be saving quite a lot of money each year and therefore make the business case for doing it,” said Smith. “But also we want to appeal to them to reduce their carbon emissions, which go hand in hand with these retrofits.”
Due to the economic recession in the United States, many green projects in downtown L.A. have been wait-listed due to a lack of funding. Financing opportunities like the Los Angeles County Property Assessed Clean Energy program, or PACE, are helping architects and developers make their green projects a reality.
The Los Angeles/Universal City Hilton hotel is the largest PACE financed project in the nation, with $7 million used for deep energy retrofits in the building. These improvements will save approximately $800,000 in energy costs and $28,000 in water costs annually.
Gensler and Cal Poly San Luis Obispo completed a study in 2013 called Capacity, that analyzed the evolution of infrastructure downtown Los Angeles and its constraints on a large scale.
“They took a look at downtown L.A., what are the current limits to growth—what can those limits become if we start taking a look at sustainability from an energy reduction point of view or taking advantage of renewable energy and reusing water?” said Brower. “So what are the real limits of downtown and what can they be if they start removing some of these barriers and addressing sustainability on a much different scale?”
The global progression of green architecture and legislature is driven by necessity and new technology. As green technology evolves, more energy is conserved, new materials are created and the technology is produced in cheaper and more sustainable form.
“I think there is this collective building up worldwide, not just Los Angeles, about the environment and the effects on the environment and we see them and it’s more concrete and it’s less abstract,” said Katsellis. “I think sustainable architecture and design is driven both by the collective, of people who are educated not just in architecture, and how it can affect environment and also by policies, which try to push things a little bit more quickly.”

YTWO Formative, the world’s first cloud-based, combined 5D BIM and supply chain management enterprise platform provider for building and housing industries, is successfully expanding its supply chain ecosystem. Recently, two of their global clients – one being CG Gruppe, a leading German real-estate developer – have placed orders through YTWO Formative’s expanding material catalog.
The YTWO platform provides the methodology for users to save significant time and money as they tackle complex construction processes. The solution is the result of a partnership between RIB Software and the Sketch-to-Scale solutions provider Flex providing invaluable supply chain management resources and expertise. YTWO Formative is the first global organization to overcome the challenges that come with meeting the aggregated demands of homebuilding communities around the world.
YTWO Formative Business Development Director, Doug Harmon said that this clients’ purchase is setting a revolutionary precedent for the residential construction industry.
“This is the first step in proving homes can be manufactured through lean processes under a single consolidated technology platform providing transparency to all stakeholders. Through mutual trust, client collaboration, agile methods, and cross-industry supply chain expertise, YTWO Formative is addressing client challenges and helping them strengthen their core business practices and competitive advantages.”
YTWO Formative specializes in a Virtual-into-Physical agile process which simulates and optimizes project plans digitally before breaking ground. Homebuilders can efficiently acquire materials from suppliers on YTWO’s BIM-based material catalog for the 5D BIM building design during the virtual planning stage. This offering is extraordinary because the homebuilding industry continues to apply analog methods when building residential communities. These traditional approaches previously created information silos between the homebuilder, the trades, and procurement processes. With this lack of transparency, information cannot flow freely and budget-detrimental inefficiencies persist.
Now, with YTWO’s real-time and optimized stream of information flowing between all residential stakeholders, the homebuilding industry has the potential to build through lean manufacturing processes. YTWO-Demand-Visibility, paired with BIM-based products, aligns material production and delivery with the construction schedule during the virtual planning phase.
About YTWO Formative
Established in 2016, YTWO Formative is a joint venture of RIB, the world’s leading web-based 5D BIM enterprise solution provider, and Flex, the global supply chain management solutions provider. Combining digitalization and industrialization, YTWO Formative offers a fully integrated end-to-end cloud-based 5D BIM enterprise platform to support the building and housing industries worldwide. The digitalized and industrialized working process can generate savings and benefits of up to 30%.


This blog explores changes in the energy industry from an insider’s perspective as it transitions from the old centralized utility model to the new paradigm of distributed generation.
This blog was previously called Inside the Housing Evolution and focused on energy efficient homes. Ultimately, it’s all linked. Soon, every building will have the potential to generate, store, and sell energy. Welcome to the era of the transactive grid – the greatest shift the electricity sector has seen in over 100 years!
3D Printing Houses – An innovative vision for the future of housing
Dr. Behrokh Khoshnevis at the University of Southern California is developing a completely new way to build houses using a large-scale version of 3D printing technology. This innovative approach, called Contour Crafting, works by using a large robotic arm with a nozzle that can spray fast drying concrete in layers according to a predetermined design. According to Khoshnevis, once fully developed his system will be able to build a 2,000 square foot house, including plumbing and electrical, in 24 hours and for 1/5th the cost of conventional construction.
There are many potential benefits to this approach besides the obvious time and cost savings. This approach would have zero waste materials, fewer greenhouse gas emissions than regular construction due to the lower embodied energy of this approach, significant safety benefits for workers, and fewer labour issues (though that may not be considered a benefit to everyone).
Dr. Khoshnevis and his team envision the technology being used to produce affordable housing, shelters for disaster relief, and most intriguing, future dwellings on the moon and mars!
I’m a big fan of factory built housing. I feel that the construction industry is far behind other industries in using automation to improve the manufacturing process. Contour Crafting takes the factory built housing concept to the next level by fully automating all aspects of construction. Granted, if it became commonplace this approach would make much of our construction labour force obsolete, however I see it as part of the larger, gradual shift in the workforce from an industrial society to an information based society. To put it another way, automation has already transformed almost every other manufacturing industry, and for the most part society has been able to adapt and benefit from the changes. Besides, these changes happen very gradually and the technology would be used in niche applications only for many years as the industry adapts.
Contour Crafting is still in its infancy and I believe there are still many technical challenges that need to be overcome before it can be used in real-life applications. As an engineer, I have some practical questions regarding its use (like how they get the concrete to dry so quickly- a major issue in conventional construction), but I believe the technical problems can be overcome. Conceptually, this is a completely innovative approach to automating the construction process, and I think that research into these types of areas are long overdue.

Wire rope is a machine, by dictionary definition:”An assemblage of parts…that transmit forces, motion, and energy one to another in some predetermined manner and to some desired end.” A typical wire rope may contain hundreds of individual wires which are formed and fabricated to operate at close bearing tolerances one to another. When a wire rope bends, each of its many wires slides and adjusts in the bend to accommodate the difference in length between the inside and the outside bend. The sharper the bend, the greater the movement.
Every wire rope has three basic components:
(1) The wires which form the strands and collectively provide rope strength;
(2) The strands, which are helically around the core; and,
(3) The core, which forms a foundation for the strands.
The core of wire rope is an Independent Wire Rope Core (IWRC), which is actually a rope in itself. The IWRC in Python rope provides between 10% and 50% (in non-rotating constructions) of the wire rope’s strength. The greatest difference in wire ropes are found in the number of strands, the construction of strands, the size of the core, and the lay direction of the strand versus the core. The wires of wire rope are made of high-carbon steel. These carbon steel wires come in various grades. The term “Grade” is used to designate the strength of the wire rope. Wire ropes are usually made of Extra Improved Plow Steel (EIPS) or Extra Extra Improved Plow Steel (EEIPS) One cannot determine the Grade of a wire rope by its feel or appearance.

We’ve written many times about how trenchless technology is a great way to minimise environmental destruction and environmental risk on pipeline projects. As we all know, by using trenchless technology, there’s no need to dig along the alignment of the pipe – meaning that everything between the pipeline start and end points – be it bushland, waterways, or protected environmental areas – can remain undisturbed and undamaged by the pipeline deep below.
We’re pleased to see that trenchless technology is being used more and more in pipeline projects here in Australia and beyond. However, with trenchless technology gaining popularity, we sometimes come across trenchless designs that lack straightforward safety in design aspects which, when implemented, can mitigate environmental risk. By reimagining designs with these simple rules applied, environmental risk can be minimised to negligible in many cases – providing positive outcomes for everybody.
So as tomorrow, June 5, is World Environment Day, with the theme of Reimagine.Recreate.Restore, let’s take a look at three great ways to incorporate safety in design into HDD crossings in order to even further mitigate environmental risk.
Rule #1: Accurate Assessment of Geotechnical Conditions
Knowing what you will need to drill through is critical to environmental risk mitigation and safety in design in every HDD project. This is because ground conditions have a major impact on risk of hydrofracture (or frac-out) – generally, the softer and more fractured the conditions, the higher the risk of hydrofracture. Knowing what you’re drilling through allows you to effectively plan your profile and alignment, tooling, equipment, drilling fluid mix, and so on, and to optimise these aspects of the project to the particular ground conditions. Leave this unknown, and you risk making poor choices and overestimating/underestimating what is needed – resulting in an increased risk of hydrofracture due to softer or weaker than expected conditions, not to mention money wasted on suboptimal equipment, inaccurate scheduling and budgets due to faster or slower than expected passes, and so on.
Knowing your ground conditions is also of huge benefit when it comes to steering the HDD crossing – more on that in rule #3.
Rule #2: Plan Your Vertical Depth
We often come across HDD designs with inappropriate vertical depth of cover – more often than not, very shallow ones. While it’s tempting to stay shallow, as this can often mean a shorter (and thus cheaper) crossing and staying in softer (and cheaper to drill) ground conditions, this can also be problematic.
Shallow crossings mean lower depth of cover above the borehole, and lower overburden pressure. Particularly in softer ground conditions, inadequate vertical depth of cover can mean that the downhole drilling fluid pressure overcomes the overburden pressure, and the fluid follows the path of least resistance to release the pressure – namely, via a frac-out to surface.
While it’s not to say that a deeper crossing is always better – there is no “one size fits all” – choosing to stay at shallower depths needs to be an informed decision. While it can be a good choice in many instances, it can be a poor one in others – so every borehole needs to be judged on its merits (and the results of hydrofracture analysis), and the best option chosen for every individual situation. If hydrofracture is not an option, a deeper, lower-risk HDD profile may be a wiser choice.
Rule #3: Optimise Your Borehole Geometry
Borehole geometry plays a critical aspect in the constructability and hydrofracture risk of HDD crossings. Basically, by minimising the vertical curve in a crossing exit to surface, steering can be simplified and hydrofracture risk decreased through rotating out at lower pump pressure. This is because, whether using a jetting assembly or mud motor, steering pilot hole tooling through a vertical/horizontal radius requires the maximum drilling fluid pressure, whereas rotating in a straight line requires lower pressure (and thus less risk of hydrofracture). While generally not so important in the deepest sections of the bore, as depth of cover provides protection from hydrofracture, it should be a vital consideration during shallower sections of the bore, such as when approaching exit – “rotating out” rather than “steering out” should always be considered first.
Understanding your geotechnical conditions also plays a major part in optimising steering. By knowing and anticipating what you will be steering through on pilot hole, unplanned deflections of the bit can be minimised. This is particularly important when using a mud motor, as the survey probe is located up to 15m behind the bit, and this unavoidable latency between the bit and the survey probe, combined with unknown geology, can result in difficulty maintaining consistency in steered direction.
HDD crossings are never “one size fits all”. What may be the best option for one crossing may not apply in another, as many individual factors must be balanced in each crossing to get the best outcome. And we’ve only mentioned three of the many, many factors of safety in design that can be applied – we haven’t even mentioned casing, entry and exit angles, or the many more that come to mind. By ensuring that you know what geology to expect, you have an appropriate vertical depth, and your steering will be simplified and as consistent as possible, environmental risk on HDD crossings can be further lowered, resulting in positive environmental outcomes – not to mention positive effects on budget and schedule too.


The City of Cape Town has amended the current water by-law. Here are three of the important changes we should note.
Amendments to Section 28(20) & (21) – Metering of Water Supplied
Landlords must keep a record of consumption by every individual unit in multi-tenant or sectional title and apartments. Previously the City could have provided multiple water connections to a property which had more than one accommodation. This is no longer the case. Only one connection will be supplied.
It is now the obligation of the owner of the property, or the person in charge of the management of the property, to install and maintain an isolating valve, along with a water management device or prepayment meter or private sub meter on all branch pipes providing a supply of water to the different accommodation units. The owner will remain liable to the City for the water supplied through the primary water connection.
Section 28 is developed in the sense that where a property has different units, where the water supply to these different units is being metered with separate private sub meters, the owner of the property or the person in charge of the management of the premises needs to monitor and record the monthly water usage of each individual unit. These records must be kept for at least 24 months.
Amendments to Section 35 – Special Measurement Of water Usage
In Section 35, the City has the power to force an owner to allow the installation of a water measuring device at any place in the water installation. The purpose of this is to ascertain the quantity of water which is being used in that specific part of the water installation. This section will be expanded to allow the City to install a prepayment meter at any such point.
Amendment to Section 57 – Wells, Boreholes, Well Points and Excavations
The proposed subsection (d) requires all owners with any well, borehole, well point or alternative water installation on their premises to register on the City’s database. Section 58 further prevents the digging of well points or boreholes without first giving 14 days’ notice to the City.
One can conclude that the above mentioned sections are progressive steps the City of Cape Town is taking in conservation and protection of our natural resource.

Rammed Aggregate Pier® (RAP) is a revolutionary soil engineering concept and ground improvement construction method using crushed aggregate to improve poor soil. RAP refers to both methods of replacement Geopier and displacement Impact pier.
Vertical ramming forces expand the aggregate pier into the adjacent soil increasing the soil density and compaction. By virtue of soil improvement by the ramming process, poor soils are improved to support shallow footings and mats, soil compressibility is controlled, and liquefaction potential is reduced. The beveled rammer head design increases the horizontal "pre-strain effect" in the matrix soil to increase bearing capacity and strength.
2. What are typical applications of Geopier and Impact pier? ^top
Geopier RAPs reinforce poor soil for heavy foundation loads. Typical applications include spread footing or mat support for buildings up to 18 stories, water and fuel storage tank support, support of MSE walls, stiff aggregate reinforcement in landslides, and general applications for sites requiring higher strength to support heavy loads.
Impact piers are commonly used to reduce liquefaction, increase density of loose sand, increase drainage of saturated soil, and increase the global stiffness of weak soil. The Impact pier is a fully cased, vibro-rod, displacement method of Rammed Aggregate Pier construction.
3. Can RAPs resist uplift forces? ^top
YES. A Rammed Aggregate Pier can be equipped with a 2-bar or 4-bar structurally designed uplift anchor. The uplift RAP can resist seismic and wind tension forces from 25 to 100 kips depending on soil conditions.
4. Does ICC, DSA and CALTRANs approve Geopier systems? ^top
YES. Geopier Rammed Aggregate Piers have been evaluated by ICC which is summarized in the ICC Evaluation Report ESR-1685 (pdf)?
YES. DSA approves Geopier for the ARC ITC Building (1997), Oakridge High School Stadium Seats (2003), Sacramento High School of Engineering Sciences (2008), Education Services Center Folsom Cordova (2010), ARC Parking Structure (2012).
DSA approves Impact pier liquefaction mitigation at Amistad Wilson High School (2010) and East Palo Alto High School (2010).
YES. CALTRANs approves Geopier. Geopier RAPs were successfully used at the 880-92 interchange project to support northbound and southbound MSE walls, 880-92 (pdf)
5. What soil conditions do Impact and Geopier RAPs apply to? ^top
The Impact Pier system applies best in loose sandy soil and fill above and below the ground water. Impact applies so-so in clay soil as well with the addition of grout.
The Geopier system applies best in soft clays, loose silty sands, soft silts, undocumented fills, and cut-to-fill transitions. If you can drill the soil, Geopier will be a highly cost effective and sound engineering solution.
6. How is corrosion of uplift steel accounted for in design? ^top
The corrosion potential is always accounted for in Geopier Uplift design. The key to corrosion protection of Geopier uplift elements is to ISOLATE the steel from all rebar in the footings and contact with the soil. In highly corrosive soil, a triple protection method is used for the uplift bars consisting of 1) oversized bars, 2) galvanization, 3) asphalt coating, and 4) poly coating. In low to medium corrosions sites, galvanized and oversized bars provide over 100 years design life.
7. How much load can a Geopier support? ^top
A typical 30-inch diameter by 12 foot deep Geopier element can resist from 50 kips in soft bay mud to 120 kips in medium clay and loose silty sand. Geopier RAPs will resist these loads with low deflections of less than 1/2 inches.
Bearing capacity is often improved upwards of 5,000 to 9,000 psf (ASD).
8. Can you build Geopier RAPs under the ground water? ^top
YES. Large open graded crushed rock is used to stiffen the soil below the water. If the soil is occasionally sandy, the drilled hole can be temporarily cased to complete the Geopier.
When the soil is predominately sand below ground water, the Impact pier system is much more effective with full length casing and vibratory displacement.
9. How does Geopier resist lateral forces? ^top
Geopier increases the allowable friction below footings. With the addition of Geopier RAPs in the soil, spread footings can resist up to 50% of the gravity building loads. Geopier RAPs exhibit tested angles of internal friction of 48 to 52 degrees.
10. How deep can Geopier RAPs and Impact piers treat the soil? ^top
Impact Piers are effective in treating to maximum depths of 45 feet.
Geopier RAPs are most effective to maximum depths of 25 feet. Geopier RAPs are commonly 8 to 16 foot deep for most building foundations.
11. Can Impact and Geopier RAPs control liquefaction of sandy soil? ^top
Yes. Impact piers can reduce and control liquefaction potential of loose sand, silty and clayey sand, and non-plastic silts. Results are measured by pre and post CPT testing to measure increased density of the soil.
12. Does Farrell have California registered engineers? ^top
Yes. Farrell has California registered engineers CE and GE. Farrell has consultant relationships and works with structural, geotechnical and seismic engineering experts in California and the west coast.
13. How do Geopier products accelerate the construction schedule? ^top
Geopier construction progresses rapidly on a clean and well organized site. Farrell's crews typically produce 40 piers per day and can peak at 50 and 60 on large jobs with 300+ RAPs. Production is a function of soil conditions and layout of the building structure.
14. What cities and counties have approved Geopier in California? ^top
Geopier foundations have been approved in San Francisco, San Luis Obispo, Santa Clara, San Jose, Belmont, Palo Alto, Mountain View, Redwood City, Newark, Milpitas, Berkeley, Oakland, Emeryville, Hayward, Dublin, Walnut Creek, Pleasant Hill, Fairfield, Napa, Richmond, Pinole, Davis, West Sacramento, Sacramento, Chico, El Dorado, Stockton, Oakley, Truckee, Tracy, Modesto, Woodland, San Diego, Irvine, Anaheim, Westminster, Oxnard, Santa Barbara, and several more cities and counties in CA.
15. How is Geopier better than a concrete pier or pile? ^top
Geopier construction results in a rough sided very dense aggregate pier. As a result, higher strengths are developed at the edge of the Geopier element when compared to a pile. Also, Geopier RAPs improve the strength the soil around the drilled hole up to a diameter from the edge.
16. How does Geopier compare to soil cement columns? ^top
Geopier construction is fast and clean. That means no muddy cement slurry all over the site and safe site conditions. With Geopier RAPs, contractors can keep schedules on-time avoiding the risks of deeper excavation due to a soft bottom. With Geopier, engineers can be assured of quality control by observing every Geopier BORIING drilled on the site, unlike ground mixing methods where they only get to observed a very small section of the completed column.
17. How are Geopier RAPs different than stone columns? ^top
Geopier RAPs are similar to stone columns in that they are both composed of aggregate replacement columns. Except that Geopier RAPs are 10 to 20 times stiffer than stone columns. This means that Geopier RAPs can carry much higher loads than stone columns and they also improve the surrounding soil much better. Stone columns create a weak mudded zone at the perimeter. Geopier RAPs create a well compacted rough perimeter with aggregate that has been rammed and embedded into the adjacent soil.
18. What is the sequence of a Geopier job complete? ^top
At Farrell we start with feasibility letters, estimating, and preliminary design. Once budgets are agreed on, Farrell prepares final stamped plans for submittal with structural sets. After plans are approved, Farrell signs a contract with the General Contractor to install load tests and the Geopier RAPs. Farrell closes the project with as-built plans and quality control records.
19. How can I get an estimate for Geopier ground improvement? ^top
Please call 530-621-4867 and ask for Sally, she can get you to the right engineer OR Fax over soil boring logs, foundation loads, and foundation plan to 530.621.4837.
Farrell can turn around a bid in a few days to meet your schedule.

The roof is one of the most important parts of your house. Unfortunately, it is one of the forgotten portions of some homes, as well. The roof ensures the safety of the whole house because it protects your family and property. Therefore, a roof needs to be strong and durable. Regular maintenance of your roofing system keeps it stable, hence keeping your valuable items and, most importantly, your loved ones secure and safe.
In addition to that, it is also very vital that you hire the best roofers Wickford for the repair or maintenance of your roofing system. Having said that, small leaks and cracks in your roof should not be ignored. You should make sure that you hire professional roofing service providers if you want your roof to be fixed. The benefits of hiring professional and experienced roofing service providers include:
- High-Quality Materials
One of the key advantages of hiring professional roofing service providers is that they use high-quality materials. Because of that, your roof will surely last longer. Roofing service providers will help you select the materials that are best for you. As a result, you avoid purchasing low-quality materials from local stores, which will not last long if used for repair. You should hire professional and experienced roofing service providers and make sure that they offer a warranty for their work.
- Correct Installation
Roofing service providers have the experience and skills to install a roofing system appropriately to protect your house. They know how to secure or protect your house from water damage and moisture problems and will even provide the right insulation. Professional roofing contractors will install your roofing system correctly, especially in sensitive areas. Most roofing contractors are skilled, experienced, and possess sufficient knowledge of roofing construction and repairs.
Repairing roofing leakages all by yourself is very risky because an accident may happen, which can lead to serious physical injuries. Hiring professional roofing contractors is your best option because they will do the task carefully and safely to make sure that you and your loved ones are safe, as well.
- Increases the property’s worth
A house with a solid roof has greater value than a roof that is already damaged. With that being said, a damaged roof reduces the value of your house and doesn’t attract several potential homebuyers. Professional and experienced roofing service providers make sure that your roof is properly modern and maintained, thus increasing the property value of your house.
A lot of homeowners think that hiring professional roofing contractors is costly. There are still those who think that roof maintenance and repair do not need professional help. But the truth is, hiring them is not as expensive as it may seem. You will end up saving a significant amount of money that could be used, otherwise, in your complete roofing replacement. Thus, whenever you need roof maintenance and roof repairs, make sure that you only contact a reliable and reputable roofing service provider in your area.

The movement of goods and people from one location to another is referred to as transportation. As civilization has advanced, particularly in terms of technology, the ability and necessity to transport enormous amounts of product or large groups of people across vast distances at high speeds in comfort and safety has grown. This article will look at traditional transportation technologies in Nepal.
Transportation is the most commonly acknowledged infrastructure for a nation’s growth among numerous infrastructures. Different types of advanced transportation have boosted our progress. People’s everyday lives are profoundly ingrained with the demand for transportation.
In this article, we are going to talk about the traditional transportation technologies of Nepal. As we know, Nepal is a landlocked country border with big countries like India and China. Nepal’s transportation system is made up of various modes of transportation.
Nepal’s transportation system is an interesting phenomenon because the country is mostly mountainous and has a rough and rugged terrain.
Here is the list of Traditional Transportation Technologies of Nepal.
Nepal offers extreme geographical conditions to test different transport systems. It has high mountain ranges that cover much of the country, as well as terrain (flat land). Rural access is a major problem in Nepal.
Settlements are scattered with few densely populated areas, which combined with the harsh terrain and unfavorable weather conditions, makes linking homes to established roads very difficult.
In the history of transportation technologies of Nepal, there were different means of transportation that were used to transport goods and people. Therefore, we use most of this traditional transportation technology of Nepal. So, now without delay, let us move on to the list.
1. Human-Powered (Walking)
Human-powered transportation, also known as walking, running, and swimming, is a type of sustainable transportation that involves moving people and/or goods using human muscle power. Walking was, without a doubt, the first means of transportation. People use to cover long distances on foot.
Human-powered transportation is still popular for a variety of reasons, including cost savings, leisure, physical activity, and environmental concerns; in some cases, it is the only option, mostly in rural areas.
2. Gravity Ropeway: An alternative transportation
The gravity ropeway operates only on gravity, without the use of electricity or other forms of external power. Gravitational ropeways are easy to use and maintain, as well as are environmentally friendly. The use of a gravity goods ropeway can help boost rural productivity.
It works in two ways: gravity sends produce down from the top, while the force of goods coming down lifts a smaller load (one-third) from below to the top. It is only suitable for the transportation of goods and not for the transportation of people.
3. Tuin Technology To Cross River
People must either swim, use a grass rope with a wooden pulley, or use simple boats to cross rivers due to a lack of proper or alternative transportation. Tuins (Wire bridges) are an indigenous Nepalese technology and one of the most common river crossing structures. It consists of a single wire rope, a pulley, and a straightforward wooden trolley.
It is dangerous and sometimes life-threatening to cross rivers using such Tunis. On June 27, 2011, a Timber Post of Tuin built across the Trisuli river in Gorkha district broke away, killing five people in the river. This type of information is commonly found in the media.
4. Improved Tuin
In Nepal, Practical Action improved the traditional Tuin system to make it easier and safer. While operating such traditional Tuins, several people have lost fingers, and there is always the risk of falling off the trolley while crossing. Practical Action also created a new pulley system that makes it easier to pull the trolley and eliminates the risk of fingers becoming trapped in the mechanism.
Improved Tuin provides improved balance and can carry heavy loads at the same time. Tuins are still used in many rural parts of Nepal.
5. Bullock Cart (Bail Gadi) and Horse Carriages
Bullock carts also known as Bail Gadis are used in villages of terai regions to transport grass or goods. Farmers have used bullock carts to transport their products to market or to ferry people. Bail Gadi was the only means of transport in rural areas who wished to travel from one village to another village. For centuries, bulls and buffaloes have been used to pull carts. In the Terai region of Nepal, bullock carts pulled by buffaloes and bullocks are still the primary mode of transportation for goods.
In the past, the horse was another popular mode of transportation for transporting people and goods. The horse-drawn carriage was one of the chief modes of transport of the aristocracy. It is a mode of transportation that has been used in many parts of the world since ancient times.
6. Donkeys use for carrying goods
Back then, donkeys were the primary mode of transportation for transporting goods from one location to another. People couldn’t carry all the goods they needed back then, so donkeys were used to transport the goods. In some remote parts of Nepal, where there are no roads or other means of transportation, donkeys are still used.
7. Cycle Rickshaw
A cycle rickshaw is a small-scale model of local transportation. Cycle rickshaws are non-polluting and offer a cost-effective way to connect the last mile. For short distances, the cycle rickshaw was one of the most popular modes of transportation in Nepal.
Rickshaws were mostly used in the Terai region of Nepal and some parts of the Hilly region. It is human-powered by pedaling or either pulled by a person on feet.
8. Doli to carry bride
It’s a piece of furniture, a customized chair, this is used to transport people. It comes in a wide range of forms, colors, and sizes. Brides are transported to religious activities or weddings in this vehicle. The bridegroom was usually ridden by Doli throughout the wedding ceremony and ceremonies.
The day after her wedding, the bride was sent it to her in-laws’ residence. Doli was carried on the shoulders of four people who walked on foot holding the bride and conveying her to the location. Marriages were often held within a 10-kilometer radius at the time, and roads and modes of transportation were few.
9. Wooden Bridge
A timber bridge, also known as a wooden bridge, is a structure made of wood or timber. From ancient times we use timber bridges which are also known as one of the first bridges.
Wood and stone were the only materials available for building bridges in the past. Wood was an obvious choice in forested areas. An early solution was to simply push trees over in order to cross rivers or ravines.
Wood took on great importance as a versatile construction material that was available almost everywhere.
There you have it, a list of Nepal’s traditional transportation technology of Nepal. With the advancement of technology, few of the above traditional transport have decreased in number but are still used if some rural areas. The advancement has not only affected transport but also tools made and used by our ancestors that are still being used in some places. We hope that learning about and reading about these tools has provided you with useful information.

What Is Construction Consulting
What Does a Construction Consultant Do?
- Disaster Prevention Plan
- Road Maintenance
- Construction Management
- Design/Construction Work
- Civil Engineering Work
- Bridge Design
A construction consultant offers solutions to issues about social infrastructure and public services such as road/bridge design, public transportation-related measures and disaster prevention while working towards the promotion of renewable energy and environmental conservation.
What Is Infrastructure?
Infrastructure is the fundamental facilities necessary for people’s lives and industries such as public facilities including roads, bridges, ports, airports, railways, hospitals and schools in addition to electricity, water and gas which support convenient, safe and secure lives. Infrastructure can be defined as all those everyday things which are required for leading a normal life.
Does a Construction Consultant Build Infrastructure?
What Differentiates It from a Construction Company?
There are five processes that must be undertaken, ranging from ‘Investigation’ to ‘operation/maintenance’, before infrastructure can be put in place.
Such processes clearly show the difference between the roles of construction consultants and those of construction companies.
Conduct ground, geological and environmental investigations to decide on the implementation of the infrastructure development and analyze and assess their results.
Draw up a specific project plan based on the investigation results and opinions obtained from intellectuals and local communities.
Design a structure based on the land, surveying the results necessary for the project and focusing on economic efficiency, convenience, good effects to be obtained, etc.
Manage the construction work conducted by general contractors as a consultant so that the structure is safely built as designed according to the process plan.
Periodically check the conditions of the facilities and draw up a plan for the maintenance, reinforcement and improvement in the durability of the infrastructure. In addition, work as a service provider by providing services in addition to maintaining existing infrastructure assets.
Chodai’s ultimate goal is to “Listen to People, and Create a Future.” We consider all things required for people’s safe and secure lives as infrastructure and spontaneously control all processes starting with the Plan, and moving to Construction, and then to Operation/Maintenance in order to offer comprehensive management services. The infrastructure service provider that we aim to become is effectively a “constructive” consultant that can meet social expectations and create a better future.


How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Transport for London has announced that its first air-conditioned tube train is ready to go into service on the underground’s Metropolitan Line. London’s mayor, Boris Johnson has announced that the new train is just one aspect of a long list of improvements he hopes to implement in the capitals transport system.
The new air-conditioned train is currently being taken care of in a north-west London train depot and when it is introduced into service it will be the first of a fleet of fifty-eight trains that Transport for London hope to have running on the Metropolitan Line by 2011. By 2015 it is hoped that air-conditioned trains, also known as Stock trains will have replaced most of the older versions on both the Circle and District Lines.
Mr. Johnson said that he intends to keep improving the transport network in London so that residents and visitors have the best possible services.
Next year will also see the completion of £1.4 billion worth of improvements to the East London Line. The Jubilee Line will also see its capacity increase by one-third.
Unfortunately some of the underground tracks are too deep to enable the installation of the new air-conditioning systems. The Northern, Bakerloo and Piccadilly Lines run too far under the ground for the hot air from trains to be expelled adequately.


Three projects planned along Highway 79 between Brandenburg and Irvington received input from residents earlier this month.
Eighty-two people signed in and good public feedback was gathered at the Kentucky Transportation Cabinet’s public meeting on June 9, at Irvington Elementary School regarding projects along Kentucky 79.
Three alternates were presented for two projects which are KY 79 from KY 477 to KY 428 (Guston Road) and KY 79 from KY 428 (Guston Road) to KY 144 (Midway Road). The goal of these projects is to improve safety and mobility along the corridor between Irvington and Midway.
Each alternate addresses issues such as improving curves and sight distance by reconstructing existing roadway with wider lanes and shoulders. Consideration is also given within each alternate to better facilitate truck traffic and to maintain traffic during construction. Each alternate involves purchasing of right of way, including potential residential and commercial relocations. The exact number of impacted properties varies with each alternate. Estimated total cost also varies with each alternate.
Currently, the project will continue up to the point of choosing between available alternates for the section of Highway 79 between Irvington and Midway. Larry Krueger, Design Engineer with Kentucky Transportation Cabinet District 4 office in Elizabethtown, says a choice will likely be made by the end of October. While funding for final design, right of way acquisitions and utility relocations was identified in the 2016 Biennial Construction Plan, current statewide budgetary constraints are anticipated to delay start of these phases.
Funding and schedules for continuing phases and construction are likely to depend on future legislative action. After a decision between alternates is made, a project update will be added to the website and mailed to those who signed in at the meeting.
These projects align with an original KY 79 project in Meade County from Midway to Brandenburg, which is already designed and is in the right of way purchasing phase. The first project is also on hold due to budgetary constraints and is currently under review.

The Des Moines Zoo will be closing its doors in 2019 and moving to a new building on the zoo’s campus in 2019.
The Des Moines Metropolitan Water Reclamation District (DMWRD) is expected to take over the zoo from the city of Des Moines.
The city will take over operating and maintenance of the facility.
The zoo’s former home was demolished in 2015 and the city is currently seeking a developer to build a new, 20,000-square-foot zoo.
The new site will feature a zoo-like theme park, a water treatment plant, a new water treatment station, a zooski and a fitness center.
The $60 million zoo will be a new addition to the zoo that will open in 2020.


SAFETY: The Harcourt rail bridge will receive an upgrade this weekend. Picture: GLENN DANIELSPLANNING to travel to Melbourne by train this weekend? Take note – rail services will be replaced by coaches June 27 and 28 to allow the Harcourt rail bridge to receive a $230,000 upgrade.
The 15 metre timber deck on the bridge will be replaced with steel.
The work will involve lifting the track, ballast and sleepers before removing the timber deck and replacing it with a new steel structure. Minor maintenance works will be undertaken at the same time.
Scheduled services will resume as normal from Monday morning.
V/Line has advised travellers to allow an extra 40 minutes travel time to and from Melbourne.
Public Transport MinisterJacinta Allan said the new deck would help keep the Bendigo line “safe and reliable for regional passengers”.
“V/Line maintenance works like these are critical to keeping our regional train network movingand I thank passengers for their patience while they are carried out,” she said.
Member for Bendigo WestMaree Edwards said the work was crucial.
“About 40 trains travel over this bridge each weekday, so replacement of the ageing deck is critical to keeping Bendigo line services safe and reliable,” she said.
Check the V/Line website for more information about changes to services.

Rogers Krajnak Architects (RKA) congratulates Construction Systems Inc. (CSI) for receiving the 2021 Build Ohio Award from the Associated General Contractors of Ohio for the Ohio Theatre Loge, Mezzanine and Balcony Renovation. Established in 1991, the Build Ohio Award recognizes contractors for construction excellence in project management, client service, craftsmanship, innovation in construction techniques and materials. The complexity of this RKA designed project involved reshaping the curved, sloped, and uneven rows in the Loge seating areas and cross aisles, relocating stepped aisles, and installing custom fabricated handrails and seating in a limited window of time while the theatre was unoccupied. Along with the new custom fabricated handholds that were installed in the stepped aisles of the Mezzanine and Balcony, the project improved patron safety in all of these seating areas of this historic theatre. RKA applauds the great teamwork with RKA, CSI and CAPA!

Below is a news release from the Wyoming Game and Fish Department.
Two state agencies have committed a combined $2.5 million toward installing wildlife underpasses along US 189 in southwest Wyoming to help reduce wildlife-vehicle collisions and improve safety.
The Wyoming Transportation Commission recently approved a $1.25 million match of the Wyoming Game and Fish Commission’s $1.25 million contribution, which will be used toward the Dry Piney wildlife crossing project north of La Barge.
“We are committed to ensuring the state’s roads are as safe as possible for the traveling public,” said WYDOT Chief Engineer Shelby Carlson. “The work will provide safe passage for wildlife to cross under US 189, keeping motorists safer. These underpasses allow wildlife to cross the roads without encountering traffic or fences and allows them to travel their historic migratory routes.”
The funding will be used toward the first phase of the Dry Piney project, which is expected to cost approximately $5.5 million. During the first phase, crews will install underpasses and fencing along a 5-mile stretch of US 189 between mile markers 86 and 90.
WYDOT has applied for $18.18 million in Better Utilizing Investments to Leverage Development (BUILD) funds to financially support subsequent work in the Dry Piney corridor. The work will consist of additional underpasses with fencing. WYDOT and WG&F plan to also consider the section south of La Barge for additional fencing and underpasses in the future.
Between mile markers 77 and 105, about 117 collisions are reported annually.
“By partnering together, we can ensure vital projects like Dry Piney get started to help mitigate wildlife-vehicle collisions,” said WYDOT Director K. Luke Reiner. “We average about 17 crashes per year along this stretch of road, which means this project is definitely needed. Wildlife mitigation is something we will continually be working on to ensure our roads are as safe as possible for the traveling public.”
The additional funding from the Wyoming Transportation Commission will help ensure the project gets started.
“The Dry Piney project cost is estimated at more than $5 million, so an additional $1.25 million from the Transportation Commission is absolutely a big boost for the project as well as the safety of the traveling public and wildlife,” said David Rael, Wyoming Game and Fish Commission president. “It’s a win-win.”
The Dry Piney project will help the Wyoming Range mule deer herd as well as pronghorn and moose movement. The total cost of all three project phases is expected to be between $12 and $36.5 million.
“This area of Wyoming has one of the highest rates of mule deer vehicle collisions,” said Mike Larson, Wyoming Transportation Commission chairman. “This project would not only help improve habitat connectivity and help conserve mule deer migrations, but also make it safer for motorists.”
WYDOT, the Wyoming Game and Fish Department and the Federal Highway Administration will also host a public open house from 5 to 7 p.m. on Tuesday, Nov. 12 at the La Barge Town Hall, 28 S. Labarge St. in La Barge. The purpose of this meeting is to share information about the development of the US 189 wildlife connectivity project and receive public feedback.

One-year review of Smart Tender e-platform: Helping property owners prevent tender rigging
Hong Kong, October 27, 2017 - The demand for buildings’ maintenance and repair projects has surged since the Government launched the Mandatory Building Inspection Scheme (MBIS) several years ago. At the same time there has been a rise of project prices and tender rigging. Considering not all property owners have related experience or technical knowledge when carrying out rehabilitation works for their buildings, in May 2016 the Urban Renewal Authority (URA) introduced the "Smart Tender" Building Rehabilitation Facilitating Services to provide professional and technical assistance for property owners of multi-owned private residential or composite buildings, aiming to encourage more owners to carry out building rehabilitation works and reduce their risk of encountering tender rigging at the procurement stage.
Since its launch, Smart Tender has received 107 valid applications and approved 59 of them, involving around 26,000 residential units. Smart Tender has gained wide attention of the media and the society, and the URA has stated that scheme has been making an impact on tackling tender rigging (Source: press release of the URA on October 3, 2017). Recently the URA also launched a Smart Tender concession scheme in response to the Government's 2017-18 Budget initiative to earmark $300 million to encourage property owners to join Smart Tender at a concessionary rate. It is devoting large efforts to promoting the scheme to the society through the media.
Since establishing the Smart Tender e-tendering platform in May 2016, C&T worked closely with the URA to deliver stable and reliable technical solutions with system enhancement and maintenance. Through this e-tendering platform, owners’ corporations can register tenders and activate the tendering procedure by publishing notices to contractors, who can then view the newly published projects and submit bids according to the tendering procedure, within which every bidder’s identity and bidding price are kept confidential. This eliminates the possibility of bidders forcing their competitors out of bidding, lowering the chance of rigging.
In the past year, C&T worked closely with the URA to enhance the system, including the addition of a dedicated document management solution to refine the process of contractor registration and administration.
The URA is encouraged that Smart Tender has received positive feedback from property owners since its launch a year ago. The team of C&T professionals will continue to contribute their best to the provision of advanced enterprise procurement management solutions that can lead more property owners to proper maintenance and repair for their buildings.

Fiberglass Guy Strain Insulators
Xiangyang Guowang's guy strain insulators consist of end fittings and fiberglass rod with HTV silicon rubber coating. They are applied for down guys or pole-to-pole guys on overhead lines.
The fiberglass rod, coated with HTV silicone rubber, is the insulating part of insulator. It will protect the power current go to the strand directly, and lower the possibility of flashover. Also it can provide a more strength mechanical load than the porcelain guy strain insulator.
The core rod is the abbreviation of the epoxy resin glass fiber drawing rod. It is the load-bearing part of the composite insulator's mechanical load and the main part of the internal insulation. It is required to have high mechanical strength, insulation performance and long-term stability. Now the core rod material generally adopts resin-reinforced unidirectional glass fiber drawing rod. It is the skeleton of the composite insulator, which plays multiple roles such as supporting the umbrella cover, inner insulation, connecting the two ends of the fittings, and bearing the mechanical load. It has a high tensile strength, generally up to 600Mpa or more, which is twice that of ordinary steel. 5 to 8 times that of porcelain materials, and has good dielectric properties and chemical resistance, as well as good resistance to bending fatigue, creep resistance and impact resistance.
The end fittings, made of hot-dip galvanized forged steel (stainless steel, or other specified materials), and are mechanically and directly crimped attached to the FRP core rod. Tensions force will be transmitted from strand to the pole. Coatings apptded by hot dip galvanizing are in accordance with ISO 1461 with the minimum local coating thickness greater or equal than 80mm.
There are different kinds of end fittings can be choosen for the guy strain insulators.
