Roof coatings are becoming more and more popular in prolonging the life of both traditional and metal roofing systems.
Roof coatings can be applied by either the rolling or spraying methods and essentially add a ‘top coat’ to the existing roofing system. No permit is usually required because roof coating is considering roof renovation. Most of modern roof coating systems are highly reflective materials, preventing flat roofs from extensive heat during sunny days. Similar to retrofitting a roof, Roof coatings are a popular alternative because it is more cost effective than a retrofit.
Additionally, compared to a retrofit which essentially adds another layer of roofing material, Roof coatings create a chemical bond to the current roofing substrate essentially ‘bulking up’ the existing system. Most coating manufacturers offer 5 or 10 year system warranties on coating Installations. Taking under consideration fact that some manufactures gives 10 years for new roofing membranes and extensive labor cost to install them, roof coating can save you 30% – 50% of your new roof project.

Septic tanks collapse
A company supplied the septic tanks needed for non-collective sanitation compliance work in a community of rural communes. Forty-six tanks ranging in capacity from 3,000 to 5,000 litres were installed.
A few years after the installation, three of the tanks started to show signs of malfunction and possible collapse.
The other parties in the claim sought the liability of the company that manufactured the tanks, and demanded that all of the installed components be replaced.
GM CONSULTANT INTERVENTION
Our loss adjuster, a specialist in Civil Engineering, participated in the counter investigations and pointed out several implementation issues that led to the failures, thereby ruling out the septic tank manufacturer’s responsibility.


How Does Washington's "Stay Home, Stay Healthy" Proclamation Affect Construction Activities in Washington?
Related Practice: Real Estate
Since Governor Inslee’s issuance of the March 23, 2020 “Stay Home, Stay Healthy” Proclamation, many within the construction industry were left wondering whether and to what extent they are required to halt their commercial or residential construction projects in Washington. This is what we know so far.
The Proclamation prohibits all non-essential businesses in Washington from operating, except for conducting basic minimum operations, until midnight on April 6, 2020. Any willful violation of the Proclamation constitutes a gross misdemeanor, which is punishable by up to 364 days in jail or by fine of up to $5,000.
Certain designated Essential Critical Infrastructure Workers, classified into 13 categories of industry sectors as listed below, are exempted from the Proclamation’s prohibition and are permitted to remain open and operating, provided such businesses establish and implement social distancing and requisite sanitation procedures.
- Healthcare / Public Health
- Emergency Services Sector
- Food and Agriculture
- Water and Wastewater
- Transportation and Logistics
- Communications and Information Technology
- Other Community-based Government Operations and Essential Functions
- Critical Manufacturing
- Hazardous Materials
- Financial Services
- Defense Industrial Base
As for construction-related activities, the Essential Critical Infrastructure Workers list exempts a relatively narrow class of construction workers and construction activities from the Proclamation’s prohibition. Included in this list are “Construction workers who support the construction, operation, inspection, and maintenance of construction sites and construction projects (including housing construction) for all essential facilities, services and projects included in this [Essential Critical Infrastructure Workers list], and for residential construction related to emergency repairs and projects that ensure structural integrity.” This exemption appears to be a catch-all for any construction activity that supports essential activities listed in the Essential Critical Infrastructure Workers list.
In an effort to provide clarifying guidance as it relates to commercial and residential construction, on March 25, 2020, Governor Inslee released a Memorandum. The bottom line of this Memorandum is that most construction work activities are not deemed essential and therefore not permitted: “[i]n general, commercial and residential construction is not authorized under the Proclamation because construction is not considered an essential activity.”
However, the Memorandum lays out three exceptions to the general ban on construction activities: (1) construction activities related to the essential activities set forth in the Essential Critical Workers list; (2) construction activities that involve public entities or governmental functions or facilities, including publicly financed low-income housing projects; and (3) construction activities that prevent spoliation or address emergency repairs at non-essential businesses and residential structures.
Activities that fall under the foregoing exceptions must establish and implement social distancing and appropriate health and worker protection measures. And, based on the Proclamation and Memorandum, it appears that only those employees that are considered “essential” under the Essential Critical Workers list may continue to work on such permitted construction projects.

Tips for Selecting Best Tiles for Your Home
In the modern day construction method, tiles form an integral part of aesthetics and functionality of your home. The modern technology has enabled different variety of tiles with varied finishes and sizes to match your need. Tiles are of different types depending on the material used, method of manufacturing, color and texture. There are mainly three types of tiles namely ceramic, porcelain and vitrified. The raw material used for all the three is sane like clay, sand and others. The difference comes in the way of burning and composition. Porcelain tiles are denser than ceramic tiles and they are hard to penetrate and have great tensile strength. Vitrified tiles can be both ceramic and porcelain and in case of vitrified tiles a different method of burning is used which gives a glass coating for these tiles. Hence vitrified tiles are sturdy and often used for paving public spaces. Tiles are also classified under glazed or unglazed, matte or glossy. Some of the tips for tile selection for your home are:
The modern trend is using ceramic tiles mimicking natural wood finishes and stone finishes for flooring and on walls in your home. While there are only handful of natural stones available, there are nearly 50 varieties of stone finish ceramic tiles available. Unlike wood and stone tiles which fade and deteriorate with time, these ceramic tiles can be used for long with same luster and shine.
Make the color selection for your tiles depending on your wall color, furniture, natural light, ambience and other factors. For home use choose ceramic tiles and for exterior use you can use porcelain or vitrified tiles.
For small spaces use medium sized tiles say of size 250 x 350 mm and for large spaces use large sized tiles. Bigger tiles create an illusion of space but the tile size must be relevant to the room size.
While selecting tile for your home, keep in mind that you need to choose a tile size which results in less tile cutting and wastage. Always select the tile size in multiples of room size for best results.
For exteriors like balcony, swimming pool, patio, lobby, porch and other spaces use sturdy stone finish vitrified tiles. They come in different sizes, colors and shapes. Use antiskid tiles by confirming their genuineness as exteriors are prone to water and moisture content.
In the kitchen especially clean and stain resistant tiles are a must. You can use either ceramic or porcelain tiles as they are non-porous and hence do not absorb moisture and stain. Avoid using glazed tiles in kitchen. For kitchen floor use anti-skid ceramic tiles.
Living rooms and dining rooms are the most used spaces in your home. Hence you need to use abrasion resistant, stain resistant ceramic tiles. You can always experiment with stone finish highlighter tiles or 3d tiles or tiles with gold/leather finish for your walls. Ultimately the tile selection for your living and dining room depends upon design, color scheme and usage.
For bedrooms which have lesser public movement, light and sober colored tiles should be used as they should reflect warmth and should be inviting for relaxation. You can choose wooden finish or natural stone finish ceramic tiles for your bedroom.
Use cement grout for placing tiles, if you are running out of budget, but it absorbs moisture. If you want a water resistant solution for your tiles, then go for epoxy, but it will be costlier when compared to cement grout.
If wall tiling is required at some places in your home, then go for borders and decors, which will accentuate the overall look of your home.
Always purchase 5 to 10% more tiles than what is exactly required, because in case of cuts and breakages, you will have the same size or colored or textured tile to complete the tiling. Extra tiles which have not been used are taken back by tile shops.
See tiles as an investment but not expenditure and never compromise with the quality of tiles.
If you are using real stone made tiles like marble, slate and others, then you must ask the selling company regarding laying techniques and maintenance tricks for that particular type of stone.
Whatever may be the nature of construction of your home, tiles add life and beauty to your home. I thus suggest you to be extra careful and study the above given tips regarding tile selection and make a viable investment. Make your home a place like heaven with your beautiful tile schemes.

The global innovation centre
Based on the site of Neovia’s head offices near Vannes in Morbihan, the global innovation centre now accommodates over seventy people (market monitoring, strategic marketing, R&D, formulation, innovation management, business development, new technologies, design thinking, digital, etc.). It is intended to accommodate other teams or partners (unions, academics, customers, and start-ups) depending on the projects being worked on.
Welcome to We’nov, our global innovation centre
Discover virtual tour of We’nov.
An innovative building designed by and for its users
Involved from the start of the project as well as in the design of the building and the distribution of teams, Neovia employees were able to decide on the choice of architect, furniture, and building operation. This co-construction approach summarises Neovia’s way of innovating which is modern and collaborative.
The building’s design and layout were developed to meet this need for transversality, creativity, and speed promoting collaborative work: formal and informal meeting rooms, open spaces, temporary offices, video-conferencing tools, “stand up meeting” rooms, many areas to meet in small groups, and a gym. Through this approach, the company’s various functions work and think together to serve the needs of our customers and partners.
A building with exemplary environmental performance
This jewel of eco-design of over 2,000 m2 was designed in accordance with BEPOS EFFINERGIE specifications for a positive energy building that produces more energy than it consumes. To cover the “domestic” needs of the building (heating, ventilation, lighting, water heating), photovoltaic panels were installed on partially vegetated roof. Surplus production can therefore be distributed to the rest of the site. All energy use is managed by a Centralised Technical Management System and load shedding is carried out according to the photovoltaic generation.
Winner of the Low Consumption Building Call for Projects launched by the ADEME in 2014, the global innovation centre We’nov has optimised energy consumption thanks to high-level thermal insulation. Heating is provided by renewable energy (aerothermal) and solar radiation through large windows. Air conditioning is passive using a system to recover the cool night air. Air is in turn circulated by a dual flow air handling unit and by CO2 detection to reduce energy loss to a minimum.


Jaycon Gear is one of the leading Jacketed Bitumen Pump Manufacturer in India. A jacketed bitumen pump is a type of positive displacement pump that is specifically designed for handling bitumen or asphalt. Bitumen is a viscous and temperature-sensitive material, and the jacketed pump is designed to maintain a constant temperature to prevent solidification or overheating of the bitumen. The jacketed bitumen pump typically consists of a housing or casing with a jacket surrounding the pumping chamber. The jacket is used to circulate a heating medium, such as hot oil or steam, to maintain a constant temperature and prevent the bitumen from solidifying or overheating.
We are one of the leading Jacketed Bitumen Pump Supplier and Exporter in India. The pump's internal parts, including the gears, shafts, and seals, are typically made of materials that can withstand the abrasive and corrosive properties of bitumen. The pump is typically driven by an electric motor or a diesel engine, and the flow rate and pressure can be adjusted to meet the specific requirements of the bitumen application. Jacketed Bitumen Pumps are commonly used in asphalt plants for the transfer and circulation of bitumen from storage tanks to mixing and blending equipment. They can also be used for other bitumen-related applications, such as road surfacing, roofing, and waterproofing. Overall, a jacketed bitumen pump is an essential component of bitumen-related applications, providing reliable and efficient transfer and circulation of this temperature-sensitive material.


Over the last fifteen years or so, I have installed numerous brick and stone patios, walkways and driveways. Here in Michigan, most paving is dry-laid, that is, there is no concrete or mortar involved in the installation process. Because concrete and mortar tend to break up over time due to the freeze thaw cycles in this cold climate, it makes sense to use a flexible base and joint filler. Until a few years ago, I used either baby sand, which tends to washed out too easily, or rough-graded sand to fill between concrete or clay pavers. I used chips n dust or stone dust or slag sand to fill between natural flagstone. Rough sand and the fillers I used between flagstones worked fairly well for keeping the joints filled and the pavers from shifting. (Of course aluminum or plastic edging is necessary to keep the edges of each project from shifting outward, but that is another subject). The real downside of these joint-filling materials is that they don't keep weeds down. And yes, there is some washout over time.

Niger State Government says it is exploring various funding arrangements for the completion of road projects across the state in addition to seeking necessary attention from the Federal Government to do the needful on its Roads that crisscross the State.
The State Government, in its plans for the Roads sub-sector in the coming year 2021, also said the State-owned Roads Maintenance Agency (NIGROMA) will be re-positioned in line with its Zero Pothole Policy to ensure routine maintenance of roads, while additional pedestrian bridges will be constructed along major highways in Minna and Kontagora to ensure safety.
Reviewing activities of the sub-sector in the outgoing year, Governor Abubakar Sani Bello said his government is not unaware that a good road network in the state will improve the socio-economic life of the people, hence the setting up of an Infrastructure Committee to review all uncompleted infrastructural projects and ascertain work status to complete them within the shortest possible time.
Speaking on behalf of the Governor, the Deputy Governor, Alhaji Ahmed Muhammed Ketso said the committee has worked tirelessly and visited all the project sites in the state adding that some of the projects have been completed in the major towns across the state. They include; 11km Kontagora Federal Highway, Kontagora township roads, Garima-Tudun-Wada Police Station road Minna and Zungeru township roads, while Bosso-Estate road is at 85% level of completion.
He said Contracts for additional roads rehabilitation and constructions were also awarded. They include; reconstruction of Minna-Kateregi–Bida road, which is a major economic nerve of the state, the dualization of Broadcasting road, the rehabilitation of Maje Junction–Kwamba–Suleja Road and some selected Suleja township roads.
Others are; maintenance of Minna City Gate-Chanchaga-Bridge – Paiko – Kampanin Dorawa – Farin-Doki, which he said are all ongoing.
In the year under review, the Governor further mentioned some roads spread across the state that are still ongoing to include; Mokwa township road, Kagara township road, Tungan Gworo-Tagwai Dam road, Abattoir road in Minna, Piggery-Morris and Piggery-Union Bank road, Gbenu road in Rijau and Gogo-Mailale to Peugeot.
The Governor informed the people that work is in progress at all the project sites across the state and expressed confidence that in no distant time, the roads will be completed and ready for use.
Similarly, the Governor said the State Road Maintenance Agency (NIGROMA) carried out routine maintenance work along the major roads and also completed 3 out of 4 Roads on London Street in Minna, river crossings, span bridges, and concrete culverts were also constructed across the state to ease the movement of goods and services particularly from the rural areas.

For more than a decade, Acorn have worked with a number of the UK’s largest commercial and infrastructure construction firms including Balfour Beatty, Skanska, BAM and LendLease across a diverse array of complex projects.
The infrastructure construction sector is one which is coming under increasing demands on performance (financial, safety, project delivery etc.) and Acorn have worked in partnership from initial bid and project team assembly to sign-off and project close.
The diverse nature of these assignments has included hospitals, prisons, nuclear storage facilities, MOD bases and road and rail networks.
The nuclear industry is arguably the world’s most challenging business sector, where the demands upon companies and the issues they face are more acute because of the nature of the work being undertaken and the high profile of the sector itself.
Companies operating in the sector, from SMEs to multi nationals, and frameworks to individual contractors, must deliver high performance and are often called upon not simply to demonstrate outstanding technical capability, but also extraordinary levels of collaboration and team working.
Safety continues to be a vital factor in gaining and retaining contracts for the maintenance, renewal and enhancement of the UK’s rail infrastructure.
In a growth sector that is undergoing its biggest modernisation programme since Victorian times, safety continues to sit at the top of Network Rail’s priorities. Safety must be seen to be embedded at every level of an organisation if contractors are to succeed in this highly competitive sector.
Acorn work with a number of specialist companies delivering strategic, engineering and project management solutions to the challenges faced by the UK industry, specifically in waste management and asset care.
Acorn has supported these firms in areas such as succession planning, senior team coaching, leadership and development, along with talent management programmes to make the most of the graduates and young engineers recruited into the business.
Manufacturing in the pharmaceutical industry is extremely competitive and volatile, consistently at the mercy of market forces. Senior managers and executives operating in this highly regulated sector need to balance many tough management issues.
In such a highly scrutinised business, managers often need to balance the conflicting needs of many stakeholders in a very public way, considering environmental, welfare and political issues whilst still producing a profit for shareholders.
Acorn has worked with senior teams across the UK to develop their ability to adapt and change for long-term survival, by sustaining high performing resilient teams.


A massive sinkhole has appeared on the main Karimabad road in central Hunza district. The 12 feet wide and 7 feet deep sinkhole goes unnoticed for weeks by government in the heart of Governor Gilgit-Baltistan Mir Ghazanfar Ali Khan’s own hometown of Karimabad. The sinkhole had appeared in early June and gradually developed over the past 6 weeks. Local boy scouts have blocked the road from both ends to prevent any fatal accident.
Recently, the expansion of Karimabad road has been approved which was inaugurated by the Governor Mir Ghazanfar Ali Khan. The contractor had dumped material weeks before the expansion survey was held, adding up to the existing traffic troubles of locals and tourists. The road expansion is set to be completed in 19 months. Despite claims that the work will start on the same day of inauguration, there has been no significant progress yet. The road widening is being carried out under GBPWD.

Building in Harbour Island: FAQ
Do I need a permit to build?
What is the cost of construction?
How strict are the building codes?
How do I choose a contractor?
May I bring in outside (non-resident) help?
How can I build the house I want and still remain sane?
Yes, several. Everyone needs to submit a detailed architect’s construction plan for engineer approval to the Ministry of Public Works before building or adding on to an existing structure. Pick up the form at the Commissioner’s office. Also, the town planning board must approve the appropriateness of the design for Harbour Island.
Non-Bahamians need an additional permit if a) The property being purchased is greater than 5 acres; b) The intention is to rent out all or a portion of the property; or c) The property being purchased is for commercial development. Non-Bahamians who buy land for which an additional permit is not required must register their purchase with the Foreign Investment Board.
Construction costs vary widely depending on the location of the construction site, the design of the building, the materials used and the finishes. Costs per square foot of finished house may be as low as $65-80 for low cost housing or as high as $400 for a luxury home with the finest finishes and details. The average seems to be about $200 per square foot.
Count on the cost being 40% higher than for a similar home in south Florida. This is mainly due to freight, duty and delivery cost to site representing approximately 65% of the F.O.B. material cost.
Very. You’ll note hurricane-proof requirements throughout the process, like 2×8-foot beams (rather than the standard American 2x4s). Indeed, building standards are higher in the Bahamas than in South Florida. The majority of homes here are of concrete block or poured concrete construction and are built to meet a very strict building code.
Inspectors periodically check on the work of foundation layers, electricians, plumbers, et al.
You’ve probably heard horror stories about lengthy delays because of logistics, but it doesn’t always happen that way. Most builders choose a general contractor, and as Susan Neff put it, “stay close to him, make certain he amintains your vision, and that his workers are following the architect’s plan.
Of course, you can be your own general contractor and hire individual tradesmen on your own as Wade Higgs has done. . Local business woman Juanita Percentie did also, and along the way learned more about construction (laying tile, wiring, etc.) than she ever though she would. “My father would be proud of me,” she said, “I’m building my own house!”.
A non-Bahamian, like an architect or someone skilled in laying marble, may be granted a temporary work permit if that skill is not available on Harbour Island; but this process is not automatic.
Chill. And remember that this is Harbour Island, and some tings take longer than you plan.


2015 promises to be a very exciting year for Perth Airport with many projects reaching completion and new projects starting.

Genetics and nutritional improvements in poultry husbandry have been extremely important to the efficiency of meat and egg production; however, the full genetic potential of poultry can’t be reached unless the proper environment is maintained in the house.The climate in poultry houses influences the well being and health of birds.In most developed countries, modern poultry houses rely upon electronic controllers. Through the use of controllers, it is possible to keep house temperatures within five degrees of the desired temperature regardless of outside temperature. This makes it possible to keep the birds comfortable so they are not diverting energy from growth to stay warm or cool.
Temperature and Relative Humidity and Air Composition inside Shed:
The highest and lowest critical temperature depend very much on: Age, Body weight, Housing system, Feeding level, Relative humidity, Air velocity and Health. The recommended temperatures are:
|First Day||1st week decrease||2nd week decrease||3rd week decrease||4th week decrease|
When outside temperatures are low, relative humidity in the house is low, which often results in dry dust circulating in the air within the house. If the relative humidity is too high, this may result in wet litter. The ideal relative humidity for poultry is 60-80%.
The gas Standard for European poultry Houses are:
|0||<2500 ppm = 0.25 vol%||<25 ppm = 0,0025 VOL%||0||0|
In order to maintain the above parameters to desired level, the environmentally constructed shed are designed as follows.
Construction of Shed:
Poultry houses are constructed with wood or steel trusses and supports. The houses are clear span structures from side wall to side wall. The trusses are engineered to support the weight of the roof without the need of support posts. The floor of the shed is compressed dirt that is covered with bedding material.For controlled-environment housing of layers, multi-tier cage systems are common. House dimensions are usually 40-50 ft wide, 400- 600 ft long with 8 ft high sidewalls.
Ceiling and Side Walls:
To improve ventilation and reduce heating costs, most houses are constructed with dropped ceilings.Insulation can dramatically affect the level of supplemental heat and ventilation requirements. Dropped ceilings protect the trusses and ceiling insulation by acting as a vapor barrier. Dropped ceilings reduce the ceiling surface area and allows for the installation of ceiling insulation to reduce heat gain in during hot weather and heat loss during cold weather. Modern houses are well insulated with blown in cellulose or fiber glass insulation.The effectiveness of insulation is measured by its R-value. Insulation values of at least R-21 and R-7 are recommended in the ceiling and walls,respectively.Houses are constructed with solid side walls which provide better insulation, reduce air leaks, provide better light control and allow the house to be heated more efficiently. The use of solid side walls provides a smooth surface compared to open sides walls with posts. This improves air speed during tunnel ventilation that will increase the cooling of birds next to the wall.
Heating systems include radiant brooders, pancake brooders, forced air furnaces and radiant tube heaters. Brooders and tube heaters project heat onto the floor. The hot air furnaces heat the air, which then heats the floor. Hot air is lighter than cold air. This can result in stratification with the air being warmer at the ceiling than at the floor. Circulation fans are often used to move hot air from the ceiling down to the floor. Paddle fans can also be used to mix air, but one should be careful to ensure that the chicks are not exposed to drafts.
Hot and Cold Weather Ventilation:
Ventilation system in a poultry house consists of fans, air inlets, evaporative cooling system and controller/thermostats. Houses are designed to deal with both cold and hot weather extremes.
During Cold weather:
Negative pressure ventilation is used to provide fresh air, remove moisture and minimize heat loss. Fans exhaust air out of the house creating a slight negative pressure inside the house. Fresh air is pulled into the house through air inlets installed either high on the house side wall or in the ceiling. The fresh air should be directed towards the roof to mix with warm air and then circulate throughout the shed. Distribution of inlets uniformly around the perimeter of the building, size of the fans and inlets are critical if all areas of the house are to be ventilated. The location of the fans and air inlets depends upon the width of the building. Fans should be placed in one side wall for buildings up to 40 feet wide. Buildings more than 50 feet wide need fans on both sidewalls. Air inlet size is critical to proper functioning of the ventilation system. The air inlet velocity must be high enough to ensure fresh air reaches all portions of the facility. However, the air velocity must not be so high that the birds are subject to draughts. Computer controlled system can be used to determine when the fans operate and for how long.
With Older Birds and in Hot Weather:
The incoming air is directed down towards the birds, and helps to keep them cool. Evaporation cooling pads can be placed in the air inlets to keep birds cool in hot weather. Tunnel ventilation is the most effective ventilation system for large houses in hot weather. Tunnel ventilation systems consists of fans at one end or middle of the house and larger air inlets at the opposite side. Evaporative cooling pads are located at the air inlets. When tunnel ventilation is not sufficient to cool the house, the evaporative cooling system is activated. Energy in the form of heat is used to evaporate water lowering the air temperature. Sometimes water will not evaporate which led to wet litter problems. This problem is corrected by moving the evaporative cooling system outside of the house.
Control of House Environment:
Almost all modern houses rely upon electronic controllers. Through the use of controllers, it is possible to keep house temperatures within five degrees of the desired temperature regardless of outside temperature. The controller monitors house environmental conditions and adjusts the heating, Humidity, ventilation and cooling equipment as necessary to keep temperatures constant. The controller operates equipment in the house including: brooders, fans, inlet machines, curtain machines, evaporative cooling systems and lights. Alarms are used to notify if there is loss of power or if the house internal temperature gets too high or too low in relation to the desired temperature or for other malfunction.


The foundation plays an important role in every structure. Without a good foundation, the building’s structural integrity will be affected. One of the signs that you have a damaged foundation is crack on the walls. However, not all cracks are created equal. There are cracks that are harmless and there are those that are pressing issues.
The problem with the regular homeowners is that they don’t know how to exactly determine the level of danger the wall crack brings. If you are like this, you can hire a professional of foundation repair Rowlett TX. Hiring a professional will help you analyze the crack and determine whether it’s just a blemish or a large issue.
Minor cracks are normal for the houses few months or years after its construction. You should be alarmed if you see horizontal cracks, separation cracks and gaping cracks might be signs that you are facing a bigger issue. In this article, we will show you how.
- Horizontal Cracks
The best way to determine if the crack is harmless; is to examine its shapes and direction. If you see a vertical crack that runs from the apex (where ceiling and wall meet), it’s a sign that the foundation experience some settling after its construction. The vertical cracks can be found in the direction of the drywall’s lines, so the cracks appear to be less serious.
However if you notice a horizontal crack at a 45 degree angle you should be alarmed because it means that your foundation is experiencing water damage or is shifting. The cracks that are not these serious are usually repaired with sanding tools, drywall putty, compounding joint and a new coat of paint. Severe cracks like horizontal cracks should be checked up by a professional. They will be able to point out the source of the damage, repair it and prevent further issues.
- Stair Cracks
Another type of crack looks like a flight of stairs, which is called a stair-step crack. These cracks appear in both horizontal and vertical directions across the structure’s walls. The pattern runs along with the cement lines and grout lines. These are mostly found in unfinished basements. Another cause of this is soil settling, again. You can tell if it should be a problem by hiring a professional to inspect the whole area and perform some tests.
- Doors and Windows
Now you’ve seen the cracks in your house, there’s another way to test if they should be a cause of alarm. Open and close the internal doors you have, the bathroom door, and bedroom door and evaluate if you can do it easily. If the doors get stuck, assess if it’s because of a cracked wood or faulty hardwood. When you swing the door, make sure that there are no obstructions because it might also a sign that the foundation is changing or shifting.
When the doors get stuck when you close or open them, it might be an indication that the doors have a twisted frame. If there’s a visible gap at the doors top and there’s a light shining through, that could be a sign of another settlement issue.


Initial Stakeholder Consultation
In the Initial Stakeholder Consultation, the target consultees will be briefed. We will introduce to the stakeholders the key opportunities, constraints and issues of each Piers. We will consult the stakeholders on the design and operational requirement, utilisation, accessibility, public safety etc. of the Piers. We will also consult the stakeholders on their views towards innovative design such as floating platform facilities for persons in need and prefabrication design if applicable.
In the Stakeholder Consultation, stakeholder consultation activities including workshops and presentations will be conducted to present the findings and recommendations of the Study with a view to gaining support from stakeholders for proceeding with detailed design.


With America’s bridge infrastructure rapidly deteriorating, wireless sensor solutions provide low cost remote damage detection and on-going health monitoring.
According to the American Society of Civil Engineers (ASCE), “One in nine of the nation’s bridges are rated as structurally deficient."1 In order to eliminate bridge infrastructure deficiency, the Federal Highway Administration (FWHA) claims that $20.5 billion needs to be invested on an annual basis.2 However, “preserving aging bridges while replacing deficient bridges is a significant challenge for cash-strapped state and local governments to manage.”3
Wireless sensor solutions, such as remote damage detection and on-going health monitoring systems, help to provide long-term resolutions for America’s rapidly deteriorating bridge infrastructure by decreasing certain costs associated with installation and maintenance.
Tracking Bridge Decay
Currently, most bridges are being inspected by people on a periodic basis. In certain environments, human inspection can be a challenge, especially if a bridge is located 100 feet above water. It can also be costly, depending on traffic control and equipment needed to fulfill the inspection requirements.
“In situations involving floods, the base of the pier is undercut, which is very difficult to detect above water,” says Rick Carlson, COO of Metrom Rail. “You would have to have a diver in the water to inspect, which can be challenging depending on the environmental conditions.”
The various elements of a bridge that can be measured and monitored to track structural decay include: temperature, humidity, inclination, strain, displacement, pressure deformation, and tilt. Slight changes in these elements can cause the structure of a bridge to move, crack, or buckle, which can lead to tragic events, such as the 2007, I-35W bridge collapse in Minneapolis, MN.4 Thirteen people were killed, and 145 were injured.5 Monitoring systems help track any structural integrity problems well before they develop, decreasing the likelihood for such tragedies.
Benefits of Sensor Solutions
The actual installation of certain monitoring systems can be expensive, especially if specialized equipment is needed to place them in the right areas of the bridge, and if traffic around the bridge needs to be delayed or rerouted. However, the expense of a sensor system is small when compared to the expense of replacing an entire bridge.
“The intent of Metrom Rail’s systems is to determine how stable a structure actually is, so that somebody can determine which structures should be a priority and worked on first,” explains Carlson.
One of the challenges for designing monitoring systems for bridge infrastructure is that no two bridges are alike. Mehdi Khandani, founder of Resensys, says “Bridges are complex. There are various types of bridges, from very old to very complicated designs.” Carlson agrees, “No two bridges are the same, because no two locations are the same. Every bridge is essentially a new application for the monitoring system, so a little customization is going to be required.”
The sensors that can be incorporated into a monitoring system include: linear sensors, tilt sensors, accelerometers, and water level sensors for bridges above water. Some examples include the LV-45 and LV-48 linear position sensors from Alliance Sensors Group, which are attached to a bridge and its supporting pier with rod-eye swivel ends. The sensors measure movement of the bridge over all three axes relative to the pier over time and ambient temperature.
“One of the biggest challenges for Alliance Sensors Group was creating a solution that could withstand the extreme weather conditions, such as snow, rain, ice, and extreme temperatures,” says John Matlack, vice president of sales at Alliance Sensors Group. “Another challenge was making the sensors low power so they wouldn’t drain the power of the overall monitoring system.”
Data collected from the sensors is used for trends analysis. “As time goes on, we learn more about what is happening with certain bridge infrastructure,” says Khandani. “By adding more data to the whole, we can track what is normal versus what isn’t normal, and produce early alerts that help to fix structural malfunctions before they cause bigger problems.”
Carlson adds,“By collecting incremental data on the bridge itself, we can determine things, like if a pier has been tilting a certain way over a certain timeframe. Once we figure out what the issues are with the bridge, we can determine which methods to use to fix them.”
For monitoring systems to be successful, the appropriate power solution needs to be incorporated. From a power management perspective, some of the major structural components on a bridge are often highly inaccessible. The cost of labor to service or replace a sensor installed on a bridge can be more expensive than the sensor itself, so long-term reliability is a paramount concern.
“We don’t have the luxury to access an unlimited power supply, or to charge it on a regular basis,” explains Khandani. “It is important for power supplies to be reliable, and for them to work over long periods of time with little or no maintenance.”
“The main concerns for power supply manufacturers are the life of the sensor, operating temperature range, the ability to replace or recharge the batteries, and, if at all, battery self-discharge,” says Sol Jacobs, vice president and general manager of Tadiran Batteries. “It is also important to know how often the battery is going to be used; if there is a standby phase; and if high pulses are required.”
Carlson explains how Metrom Rail uses available power at the sites to communicate to the bridge through a cell modem. “We have individual nodes that we apply to several piers on the bridge. These nodes are tied together with an RS485 system, so there are wires involved. Power goes through a central processing unit, which has a battery back-up.” He continues to explain that in situations not involving power, systems are able to operate using solar cells.
The power supply depends on the application it is powering. Jacobs asserts, “If the sensors can be located where there is sunlight, then they can be solar powered with a rechargeable battery used for energy storage. If not, then a long-life primary lithium battery is required, with bobbin-type LiSOCL2 batteries offering a long operating life due to their low rate design."
Power decisions depend on the expected lifetime of the sensors and how often they communicate. One example is the SenSpot integrity sensor from Resensys, which takes readings on a variety of elements once a minute, drawing only microwatts of energy. “We also developed a proprietary low power communications protocol for our wireless network to further minimize energy consumption,” says Khandani.
Wireless sensing and monitoring systems are a step in the right direction to maintain current and old bridge infrastructure. However, the ASCE claims that federal, state, and local bridge investments are not keeping pace with the growing costs of aging bridges. “The FHWA estimates that the current cost to repair or replace only the deficient bridges eligible under the Federal Highway Bridge Program is almost $76 billion. […] If bridge maintenance continues to be deferred over the next 25 years, these backlog costs will rise.”6
To put these numbers in perspective, over the last 30 years Congress has provided approximately $77 billion to the states through the federal-aid bridge program.7

* The Golden Horn Metro Bridge was completed in 2014
|Model of proposed Haliç Metro Bridge (Golden Horn Metro Bridge). Image: City of Istanbul|
|Resadiye Avenue with typical Istanbul traffic. Image: Brian Stokle/Urban Life Signs|
The conflict isn't so much about the need for a bridge, but where the bridge goes on the Golden Horn, and the height of the bridge towers. The cable-stay bridge towers will go high enough to block or distract views of the Süleymaniye Mosque, one of the most significant in Istanbul. In addition, the bridge will essentially go right towards the mosque, meaning that views from the mosque will be dominated by the bridge. As a comparison, imagine the San Francisco Bay Bridge going straight to Coit Tower, or a bridge from Manhattan to New Jersey passing a few hundred feet from the Statue of Liberty.

With that said, we grudgingly advocate the bridges construction. Unfortunately, if the bridge design falls short of gracefulness, and integration into the area of the Golden Horn, it's unlikely a "fix" could be made to make the bridge more attractive. Only time will tell if the bridge blends in well and is accepted by Istanbulites.


The Water Balance Express is an excellent tool, showing some of the ways that rivers and streams in the Township of Langley can be sustained. It supports the Township’s Sustainability Charter, which aims to conserve and enhance our environment, promote stewardship, and increase biodiversity and natural capital. Rivers and streams are part of that natural capital, and are impacted by alterations of natural forested land cover. The Water Balance Express applications for “Slowing, Sinking, and Spreading Rainwater” can help identify opportunities for mitigating those impacts.
The Township of Langley is doing its part to protect natural areas and to slow, sink and spread rainwater. Protection of greenways and riparian areas is embedded in the Official Community Plan. Standards and requirements are in place to implement rainwater management concepts as part of new projects, subdivisions and developments. The concepts are achieved by providing infrastructure such as detention ponds, rain gardens, and infiltration trenches.
We encourage you to try the Water Balance Express to see what changes you can do on your property to promote positive impacts!


On Wednesday, July 22, the EPA CHP Partnership (CHPP) and the CHP Association (CHPA) will co-host a webinar about the LEED® point impact CHP can have on buildings seeking LEED® certification.
CHP, also known as cogeneration, has a long record of providing buildings with reliable electricity, steam, hot water, and cooling with lower cost and emissions than grid-supplied electricity and an on-site boiler. New modular CHP units, absorption chiller improvements, and 3rd party ownership models have also made CHP more viable for a wider array of applications. And, because of its superior energy efficiency and lower energy cost, CHP can earn buildings seeking LEED® certification significant LEED® points.
This webinar will highlight:
• The significant LEED® point impact CHP can have on buildings seeking LEED® certification
• How CHP is accounted for in the LEED® for Building Design and Construction: New Construction and Major Renovations rating system (LEED® BD+C: New Construction).
• The contribution of modern absorption chillers to efficient building design and a building’s LEED® score

An innovative architecture is one that is modeled to respond to the needs of the client and the environment. Depending on the purpose of the project, models can be developed from a wide variety of materials, including wood, blocks, frames and paper. Different scales are used in models to display perspectives, shape, layout and details of a structure, a feat that may be difficult to attain using traditional 3D rendering or drawing. For clarity purposes, the specification information that comes with architectural design models includes; the size of the model, duration of design, build time, type of software and the number of layers used. According to White Clouds, architectural models offer a visual glimpse into how a structure will look like once it’s complete. Models serve various purposes in the design and development process, including:
1. Offers a preview of new construction
Architectures often use models to create an early representation of the complete project. The models are usually constructed using the same dimensions as the real construction, but with different scales. Through the models, stakeholders in a project can visualize the end product and make necessary amends before completion.
2. Selling and marketing real estate
Many firms and individuals understand the potent power of models as an exceptional sales and marketing tool in real estate development. Case in point, a developer can use a scaled down model to provide a vivid glimpse of a housing or office development and present it to potential clients looking to stake a claim, buy or rent the units.
3. Allows scaling of projects of various magnitude for showcasing
Developers can take advantage of the wide audiences that visit trade shows to showcase their projects using models. Through the display, stakeholders and members of the public can learn more about the project, the firms participating in the project and what to expect in future.
4. Used by homeowners and city planners to offer to build approval
In most jurisdictions, an architectural scale model may be requested by an association or city before handing over the necessary permit for construction to commence. The presented models allow the planners to look at the overall outlay of the structure to ensure it follows the guidelines of construction.
5. Tool to engage the public about a project and raise funds
Models provide a clear platform of reference, which can be used by developers to engage the public or create awareness about a project. The opinions derived from such public displays can go a long way to shaping public opinion regarding the proposed project. This strategy can also be used to raise equity from prospective investors or donors interested in the project.
According to 3DConnexion.com, the additional benefits of using advanced architectural design models such as 3D CAD in disciplines such as engineering and architecture include ability to prevent costly mistakes; provides an opportunity to showcase creativity and it saves time. The re-emergence of model driven architecture has been enhanced by the development of sophisticated apps that can be easily uploaded on the phone and computing devices.


A plumbing system is a complex network of pipes, fittings, and fixtures that deliver water and drain waste. These systems are vital to the safety and health of residents.
The primary function of the plumbing system is to bring in and distribute freshwater to various parts of a building. It also removes wastewater and disposes of it properly.
Whether it’s the piping system that brings water to your house or the one that removes waste, plumbing is an important part of your home. And when something goes wrong in the system, it’s essential to know what’s happening. A plumber in Salisbury can detect leaks, clogged drains, and check the plumbing system altogether to fix any problems.
First, let’s look at the water supply system that brings freshwater into your house. It works through a humongous pipe called the ‘main’ and it comes from the source of your city water or well (depending on what type of water you have).
When the water enters your house, it’s under pressure which allows it to move around corners or up to the second floor. It then splits into hot and cold lines that run to all the fixtures in your house.
The wastewater system is the other subsystem of your house plumbing and it literally takes away all that garbage. It works through a drain that’s sealed with traps and vent pipes that admit air to and exhaust air from all parts of the system powerful idea.
A plumbing system consists of two major systems: the water supply and the drain waste system (DWV). The water supply system sends clean, fresh water into each fixture in your home.
The drain waste system is responsible for disposing of any wastewater that your fixtures, such as toilets, sinks or showers, discharge. This process usually involves a sewer line or septic tank on your property.
Every plumbing fixture has a drain pipe that collects used water and waste. These pipes drain to the main drainage system through gravity.
The drains are plumbed at each plumbing fixture with a slope to help water flow freely. The main drainage system also has vent piping that provides air pressure to help drain water flow smoothly mynoteworld.
Plumbing vents are a vital part of your home’s drainage system. They bring fresh air to all of your water fixtures’ drain pipes so that wastewater can move through them properly each time a sink, bathtub or toilet is used.
They also help to eliminate sewer gas buildup in the drain pipes and prevent waste odors from escaping. This makes your house a healthier place to live, and it is especially important for older residents or those with breathing difficulties.
Generally, your house has a vent stack (see ‘What Is A Vent Stack’) that extends up from the various drainpipes. These vent pipes, which carry waste gas up from the drains to the roof of your house, lead to a pipe that carries the sewer gas out of your home.
When the vent pipes in your plumbing system become blocked, they can cause a negative air pressure to build up inside your drainage system and make it difficult for water to drain. This can result in slow drainage, gurgling sounds and smells of sewer gas throughout your home.
Plumbing systems are pipes and fixtures that distribute and use drinkable water, as well as dispose of waste. They are also called drainage and vent systems.
Drainage systems are a crucial part of every plumbing system. They take all the wastewater produced from buildings and send it to a sewer facility, where it undergoes treatment and disposal.
The waste disposal process can be a complex and expensive one. However, it can be done in an environmentally friendly way.
For example, any broken parts of pipe can be recycled and taken back to your supplier, or any off cuts of tube or insulation can be used on the next project.
The most efficient way to minimize the waste created is by only disposing of non hazardous and non-harmful waste products down the drain. This is especially true when it comes to chemicals that are reactive or pyrophoric in nature. These chemicals can corrode and damage piping, preventing the proper treatment from taking place FAQ BLOG.


(Manufactured and Natural Stone Veneer)
Natural stone veneer
Stone veneer can be natural or manufactured. Natural stone veneer is made from real stone that is either collected or quarried. The stone is cut to a consistent thickness and weight for use as a veneer. This stone is often called thin stone veneer. Some companies offering this type of veneer are Realstone Systems, Erth Coverings, Masonal Stone, Robinson Rock, etc.
Manufactured stone veneer
Manufactured stone veneer, such as Cultured Stone, Eldorado Stone, Renostone, Impex Stone, etc., is a decorative building material manufactured to replicate the look of natural stone. It is fabricated by pouring a lightweight concrete mix into painted rubber moulds of different styles which, when dry and unmoulded, have the appearance of real stone.
The advantages of manufactured stone veneer over natural stone are:
- Lower cost (cost of material, cost of installation)*;
- Lower weight (easy to install and easier to cut)*;
- Wide selection of styles in different colors.
* Manufactured veneer is approximately 1/3 to 1/2 cheaper than natural stone.
Downsides include a higher rate of rejected pieces, unrealistic appearance of some models, hard to remove stains and unconcealed mortar in side cuts.
Its light weight eliminates the need for wall ties, footings or a supporting structure system thus making it easier and cheaper to build. The variety of designs and colors available allow applications which would not be possible with load-bearing stone.
A wide variety of ceramic tiles are available on the market. Whether it be floor or wall applications, CSA Construction Inc. can assist you with your tile installation.
Every project requires intricate and detailed work in order to create the space you’ve always wanted. CSA Construction Inc. workmanship guarantees your total satisfaction!

Just like stone, wood is a very popular natural material. Its organic look adds richness and character to any project. Whether you want a polished look or a rustic one, we can help you achieve the look you want.


Septic systems are underground wastewater treatment structures, commonly used at a home in the countryside that is not connected to any city sewer line. Using a combination of nature and proven technology to treat wastewater from household plumbing produced by bathrooms, kitchen drains, and laundry. A typical septic system has four main components: a pipe from the home, a septic tank, a drainfield, and the soil.
Leach Fields: Rooter man can locate your leach systems by using a camera and map them out. Rooter man can also clean and service leach systems. If your leach field needs repairs we can make those repairs to the existing leach system as well as upgrading an existing leach system.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the wastewater will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
Tank Repairs: Rooter man can install new baffles on your existing septic tank as well as risers and lids. This will allow access to the tank and provide better aeration to the septic system. We can also seal the inside of a septic tank.
Sewer Ejector Pumps: A sewage pump which is ideal for most residential applications will only need to pump up to 20 feet of lift to a gravity sewer. A typical sewage pump installation is when there is a bathroom located in a basement that gets pumped to a gravity line which is connected to the gravity sewer or septic system. Sewage ejector pumps cost less than true grinder pumps.
Sewage Ejector Grinder Pumps: True grinder pumps will actually shred the sewage and then pump it through the pipe. The main benefit of using a sewage ejector grinder pump is that paper and other debris that get flushed down the toilet are grinded down to help flow through the sewage system more efficiently and not cause clogs in the pipes. These are powerful pumps, and until recently most sewage grinder pumps have only been available for commercial use in Santa Rosa, CA but are now available for residential usage. Grinder pumps are usually installed where the sewer is a long distance from the home, or there is a high vertical lift of more than 20 feet or so
