It is unlucky that a large number of your time roofings on commercial properties are actually frequently disregarded until there is actually a huge complication, like a leakage, skipping shingles, or even water dependent to the roof of the commercial structure. When a complication gets to be very large, most companies are actually tense to determine that it will certainly cost a great deal of loan to have it repaired. Like with a bulk of factors, it is regularly far better to capture any kind of concerns while they are still little, which is actually why preventative commercial roof maintenance is actually consistently advised. Having normal commercial roof routine maintenance is important given that roof coverings are actually not the simplest to acquire accessibility to for appropriate evaluation. The longer a business permits a trouble with the commercial roof to continue, the additional amount of money they are likely to devote repairing it. It is crucial to bear in mind, as an example, the water leaks in roofings cause water to receive caught in the roof. If not corrected right away, the stationary water will continue to create, creating the formation of mold and mildew. Certainly not simply performs mold have the probability of leading to injury to the structure of the commercial structure, but it can additionally cause staff members to get ill.
Possessing normal preventative commercial roof upkeep will definitely conserve money because if there needs to have to become repair work, they are frequently minuscule and also carry out not cost a lot. Normal maintenance is going to additionally maintain the long life of the roof – business will certainly certainly not need to substitute the roof as typically. Not merely that, yet companies will certainly not need to pay for compensation to employees that get sick because of the increase of mold and mildew in the structure.
Commercial services ought to have their roofing systems checked by a roof servicing provider a minimum of pair of times during the year. Among the scheduled appointments should be conducted after the winter months as heavy snowfalls might trigger the structure of the roof to come to be weak, possibly causing the failure of the roof. Likewise have actually an inspection carried out in the fall, just before the winter months starts. If there are actually any weak spots, they may be taken care of prior to the snowfall loss occurs as well as make sure s the water drainage unit on the roof is working at an optimal level.
An excellent commercial roof upkeep inspection will definitely consist of things including securing water pipes and also vents, dealing with exposing nails, getting any sort of loosened shingles, getting rid of any type of added particles, and also checking and also doing minor repairs. All this preventative roof servicing will certainly make certain the roof lasts longer and also costly potential fixings are avoided.
When it pertains to employing a firm to accomplish preventative commercial roof upkeep once or twice a year, it is very important for businesses to find a really good, expert commercial roofing provider. A qualified commercial roofing provider will definitely give a ton of information throughout the training course of the roof examination, including photos of all issue locations along with an in-depth description of what they carried out to repair it, a description of the existing roof structure, a checklist of any sort of encouraged substitutes or repairs that will make the roof stronger and increase its own life expectancy, and a price quote of the life cycle of the present commercial roof. Possessing frequent commercial roof routine maintenance makes certain the roof keeps powerful and also the inside of the building stays completely dry and secure.

Brasilia by Bicycle
Riding a bike in Brasilia can be a challenge if you do not stick to the designated bike lanes. If you ride on the main roads, extreme cautious is advised as not all car drivers are respectful of bike riders. Also watch the many potholes in the road and the bike lanes.
Currently Brasilia has over 420 km of designated bike lanes and is planning to extend that to over 1200 km in the coming years.
In Lago Sul and Lago Norte there are extensive bike lanes which are safe. In the Jardim Botânico neighborhood bike lanes exist on the main road only and if you want to ride over the Juscelino Kubitschek Bridge, Ponte das Garças and Ponte Presidente Costa e Silva (the three bridges connecting Lago Sul with Asa Sul) there are no specific bike lanes, so one has to be extremely careful.
In the Plano Piloto area there are plenty of bike lanes.
Parque da Cidade Sarah Kubitschek, or Parque da Cidade, is the main park in Brasilia and located in Asa Sul. This is a place where you find plenty of designated bike lanes which can get very busy on weekends.
You will find plenty of off-road bike trails around Brasilia.
When riding a bike it is advised that you carry a puncture repair kit with you.

Energy and environmental costs in the brick making industry are escalating hugely. An opportunity to positively affect maintenance and service costs was considered valuable by one of the, already, most efficient manufacturers. A 500hp motor driven clay extruder gearbox had been in service for several years with rebuild intervals of approximately 7 years. During the interim the first input pinion gear is subject to replacement at 12 – 24 month intervals. Start up is helped by an air bag to cushion the otherwise full load onto clay filled screw. Gearbox oil is changed at 18-month intervals.
During the most recent gearbox rebuild, which involved replacing approximately £40,000 worth of components, an addition of Lofrix® was made to the new oil fill.
Compared with average power consumption prior to the rebuild, power consumption was reduced by more than 5%.
When the oil was changed at 18 months, the magnetic plug in the gearbox was found to be free from steel or iron particles.
Both at that time and again at two years the input pinion was found to be completely free of damage, thus avoiding a costly stoppage.
All 3 gearboxes on the extruder been treated resulting in significant financial savings being made in both running and maintenance cost.

This report presents the findings and conclusions of a four-year study of the collapse of World Trade Center Building 7 (WTC 7) — a 47-story building that suffered a total collapse at 5:20 PM on September 11, 2001, following the horrible events of that morning.
The objective of the study was threefold: (1) Examine the structural response of WTC 7 to fire loads that may have occurred on September 11, 2001; (2) Rule out scenarios that could not have caused the observed collapse; and (3) Identify types of failures and their locations that may have caused the total collapse to occur as observed.
The UAF research team utilized three approaches for examining the structural response of WTC 7 to the conditions that may have occurred on September 11, 2001. First, we simulated the local structural response to fire loading that may have occurred below Floor 13, where most of the fires in WTC 7 are reported to have occurred. Second, we supplemented our own simulation by examining the collapse initiation hypothesis developed by the National Institute of Standards and Technology (NIST). Third, we simulated a number of scenarios within the overall structural system in order to determine what types of local failures and their locations may have caused the total collapse to occur as observed.
The principal conclusion of our study is that fire did not cause the collapse of WTC 7 on 9/11, contrary to the conclusions of NIST and private engineering firms that studied the collapse. The secondary conclusion of our study is that the collapse of WTC 7 was a global failure involving the near-simultaneous failure of every column in the building.
All input data, results data, and simulations that were used or generated during this study are available at http://ine.uaf.edu/wtc7.

One of West Virginia's most beloved covered bridges is the Philippi Bridge. Constructed in 1852 by Lemuel Chenoweth at a cost of $2,151.24, the bridge remains in use today.
During the Civil War the bridge served both North and South in passage of troops and supplies across the mountains into Virginia. Several times the bridge narrowly missed the fate of many other wooden structures along the Staunton and Parkersburg Turnpike that were burned.
The dual-lane structure was made of yellow poplar. Masonry work used native stone; and iron bolts, the only metal used, were made by local blacksmiths.
When modern traffic loads were too much for wooden floor beams, officials constructed hearings to decide whether to repair or replace the span. In 1938 the bridge received two additional piers, a steel reinforced concrete floor, and a walkway to handle more safely the black porn
increased demands of vehicular and pedestrian traffic. This brought the bridge's weight capacity to ten tons.
Following the fire in 1989, the $4 million project, using as much of the original material as possible, restored the structure to its original appearance. Additions of lighting and a sprinkler system have not detracted from the authenticity.

Arizona Restoration Specialists provides four warning signs of a slab leak and how to handle the water and mold damage that can result.
Arizona Restoration Specialists, the area’s leading team of water damage restoration specialists, knows that the disruption and inconvenience resulting from a water damage incident can be stressful. Water damage, if not taken care of immediately, can lead to mold growth, which can cause serious health issues. Watch for these warning signs of a slab leak in order to keep a home or business dry, safe, and structurally sound.
Occasional water leaks in a home or business are a part of life. The most common leaks are easy to access and repair. Since these leaks are usually easily detectable, they are repaired before much, water damage occurs.
What Is a Slab Leak?
Unfortunately, some leaks are hard to spot, difficult to access, and complicated to repair. Most homeowners may not notice when a pipe underneath their home’s slab foundation has a leak. The leak can damage the concrete foundation and cause buckling and shifting, and the home’s walls and floors can develop cracks. Leaks inside the house can result from the disruption.
How Common Are Slab Leaks?
The frequency of slab leaks varies depending on certain factors. Slab leaks might be a concern in those areas of the state that experience earthquakes. A recent news report headline described Arizona as “A State On Shaky Ground.” The article went on to report that, “Within Arizona, at least 20 quakes of magnitude 5.0 or higher have struck since 1850.” Arizona ranks high among states with frequent earthquakes.
The shifting ground from an earthquake exerts tremendous pressure on pipes and may cause them to shear or crack, causing leaks. In older homes, corroding copper pipes and deteriorating sewer pipes can lead to slab leaks. The potential for water damage is great. A broken water pipe can spew eight or more gallons of water per minute into a home.
Warning Signs of a Slab Leak
Homeowners who suspect they have a leak underneath their home’s slab foundation should look for the warning signs listed below. These warning signs will also aid in locating the source of the leak.
Warning Sign #1: Warm Spots on the Floor
An abnormally warm spot on the floor may indicate a leaking hot water line in the home. If the floor is carpeted or covered by thin linoleum, then detecting a warm spot should be easy. Locating a warm spot under a tile floor is more challenging unless water is seeping through the foundation and settling under the tile. The leak may be so severe that it floods the room and pools on top of the tile floor.
Finding a warm spot under wood or laminate flooring may not be so easy either. By the time the visual signs of a water leak appear, the damage may be well underway.
Warning Sign #2: Raised Dome-Shaped Area in the Floor
A major leak that goes unrepaired may damage the flooring in a home. Warping and buckling in the flooring may appear. The formation of a dome or raised area in the floor is a common occurrence in severe water damage under a slab. The presence of the deformity in the flooring may indicate the location of the leak and the presence of water inside the home.
An inspection of flooring, baseboards, and sheetrock throughout the house will provide the homeowner with some idea of the severity and extent of the flooding. The flow of water into the home could be minimal. However, over a period of days, weeks, or months, water could have been seeping out from under the flooring and been wicked by the baseboards and sheetrock. Look for peeling paint, stains and discoloration, water-logged baseboards, and warps and waves in the sheetrock.
Warning Sign #3: Foundation Heaving
A leak under the slab can cause the concrete to swell. Extreme swelling can slightly lift the building. This lifting is referred to as heaving. If a home has undergone sudden, significant heaving due to a leak underneath the slab, severe and possibly irreparable damage to the home could occur. Cracks in the walls, ceilings, and floors can indicate that heaving has occurred. The matter needs immediate expert attention to address structural concerns.
Warning Sign #4: Sky-Rocketing Water Bill
A spike in the water bill for no apparent reason should give the homeowner pause. The sudden, unexplainable rise in the bill could be an early sign of a severe leak. The homeowner would do well to inspect the home for water damage from other sources such as a leaking toilet, shower, or sink.
Next Step? Call Arizona Restoration Specialists
Allowing a slab leak water damage incident to go unresolved can lead to advanced secondary water and mold damage, which is more complicated and expensive to repair. Serious health issues can arise from a mold infestation. Insurance companies have been known not to cover water damage claims where the homeowner has neglected to take immediate action to resolve the matter.
For water, fire, flood, and mold damage restoration, contact Arizona Restoration Specialists. The team has more than 20 years of experience serving The Grand Canyon State with topflight water damage restoration services. Crews are on call around the clock, 365 days a year, and can be on the scene in one hour. Services include water damage restoration and related issues such as mold removal and remediation, sewage cleanup, fire damage restoration, and repair and reconstruction.

Blower Door Testing or Building Envelope Leakage Testing is a crucial inspection that measures the air infiltration of the building envelope. It is recommended as the final inspection before the completion of your project and is necessary for obtaining a Certificate of Occupancy for all new home construction. The testing process typically takes around an hour, and you will receive the results immediately upon completion. Ensure the efficiency of your building by scheduling a Blower Door Test today.
Duct Leakage Testing is vital for measuring the amount of conditioned air that is lost due to leaks in the ductwork. To ensure that any necessary repairs can be made, it is advisable to have this inspection conducted prior to drywall installation for new construction projects. The results of the test will be readily available as soon as the inspection is completed, allowing for prompt action to enhance energy efficiency and optimize the performance of the HVAC system.
Thermography is a method of capturing surface temperatures using infrared video and still cameras, enabling the visualization of heat patterns. It is a valuable tool for identifying possible issues or anomalies that may be present during a building performance analysis. We highly recommend incorporating thermal imaging scans into any type of building performance testing, as they can provide valuable insights into potential areas of concern that may not be visible to the naked eye. By utilizing thermography, our clients can gain a more comprehensive understanding of their property's condition and make informed decisions based on the findings.

Architecture is an art form that has always fascinated people from various walks of life, and it’s known for its ability to infuse functionality with beauty. One of the elements that distinguish architectural structures is fenestration—the arrangement and design of windows, doors, and openings. In architecture, Muntins and Mullions are two terms that are commonly used interchangeably, yet they each have a unique significance in architectural window and door design. In this article, we’ll delve into the world of Muntins and Mullions and explore their similarities and differences in architectural structures.
Understanding Muntins and Mullions in Architecture
To begin, we must first define these two terms. A Muntin is a small bar or strip of wood, metal, or other material that divides a window, panel, or door into smaller units. It helps to provide structural support and stability, as well as facilitate the installation of individual panes of glass or other fenestration materials. A Mullion, on the other hand, is a vertical bar or column that provides support to the overall structure of a window or door. It helps to distribute the weight of the structure evenly and can be used to create multiple-window units within a single opening.
Exploring the Purpose and Function of Muntins and Mullions
Muntins and Mullions serve the same basic function in architectural structures: to provide support and stability, as well as to divide an opening into smaller units. This is particularly useful when a large expanse of glass is required but where it is necessary to maintain the structural integrity of a building. However, along with this function, Muntins and Mullions also have aesthetic applications, bringing a certain character to the design of a building. They can provide a sense of scale to a structure, such as when a window is divided into smaller panes and can also be used as a decorative element in the overall design of a building.
Another important function of Muntins and Mullions is to enhance the energy efficiency of a building. By dividing a large window into smaller units, Muntins and Mullions can help to reduce heat loss and gain, which can lead to lower energy bills and a more comfortable indoor environment. Additionally, Muntins and Mullions can be designed to accommodate different types of glass, such as insulated or low-e glass, which can further improve the energy efficiency of a building.
Finally, Muntins and Mullions can also be used to create unique and interesting patterns on the exterior of a building. By varying the size, shape, and placement of Muntins and Mullions, architects can create a wide range of designs that can add visual interest and depth to a building’s facade. This can be particularly effective in historical or traditional buildings, where Muntins and Mullions can be used to create a sense of continuity with the surrounding architecture.
What is a Muntin and How is it Used in Windows?
As mentioned earlier, a Muntin is a small bar that is used to divide a window into smaller panels. Muntins can be made of various materials, including wood, metal, vinyl, or fiberglass, and can be either fixed or removable. They are typically used in traditional or historic buildings as they add a unique character and are considered as historically accurate designs.
The Different Types of Muntin Designs
Muntins can create different designs within windows, such as a Georgian, Colonial, or Victorian style. Georgian windows have a simple, elegant design with a single, thin Muntin dividing the window into two panes. A Colonial design, on the other hand, features two sections, each with multiple Muntins creating the illusion of divided light. The Victorian design incorporates multiple Muntins of varying shapes and sizes which collectively create a more intricate and ornate window design.
Another type of Muntin design is the Prairie style, which was popularized by architect Frank Lloyd Wright. This design features horizontal and vertical Muntins that create a grid-like pattern, giving the window a modern and geometric look. Additionally, Muntins can also be used to create custom designs, such as a company logo or a specific pattern, adding a personalized touch to the window.
It is important to note that Muntins not only add aesthetic value to windows but also serve a functional purpose. They provide additional support to the glass panes, making them more durable and resistant to breakage. Muntins also help to improve energy efficiency by reducing the amount of heat transfer through the window, resulting in lower energy bills and a more comfortable living space.
What is a Mullion and How is it Used in Architecture?
As discussed earlier, a Mullion is a vertical column or bar that is used in architectural structures to provide support to window frames, panels, and other fenestration materials. Mullions can be made from various materials, such as wood, metal, or concrete and can be designed in various shapes and sizes to match the aesthetic of the structure. Mullions are also used to link windows together to form a larger window unit, making them a very versatile and useful element in architectural design.
The Role of Mullions in Structural Support
Mullions are critical in providing structural support to window frames and other fenestration materials, especially in high-rise buildings. They transfer the weight and stress from the frame above to the frame below, thereby helping to distribute the weight and prevent damage and deformation. Mullions can also offer support to other architectural features such as arches, canopies, and lintels.
Another important function of mullions is to enhance the energy efficiency of a building. Mullions can be designed to include thermal breaks, which are materials that prevent heat transfer between the interior and exterior of a building. This helps to reduce energy consumption and lower heating and cooling costs. Additionally, mullions can be used to hold insulated glass units, which further improve the energy efficiency of a building by reducing heat loss and gain through windows.
Muntin vs. Mullion: What’s the Difference?
While Muntins and Mullions share some similarities, they also have distinct differences. A Muntin is generally horizontal in design and serves as a structural divider in a window or panel. In contrast, a Mullion, which is vertical in design, supports the structural framework and overall weight of a building, including its fenestration materials. Both elements are essential in creating a harmonious balance of aesthetics and functionality in any architectural structure.
Comparing the Aesthetic and Functional Differences
When it comes to aesthetics, Muntins are usually smaller and thinner than Mullions and are often used to create a visual division between panes of glass or other fenestration materials. Conversely, Mullions are typically bolder and more prominent and are used to provide architectural support and bold visual lines. Function-wise, both elements provide stability and support in structures and enable a designer to create a variety of design styles and options.
It’s important to note that while Muntins and Mullions are commonly used in traditional architecture, they can also be incorporated into modern designs. In contemporary structures, Muntins and Mullions can be used to create a minimalist look by using thin, sleek lines. Alternatively, they can be used to create a bold, industrial look by using thicker, more prominent lines. Regardless of the design style, Muntins and Mullions remain essential elements in creating a visually appealing and structurally sound architectural structure.
Choosing the Right Muntin or Mullion for Your Project
When selecting Muntins and Mullions for your architectural project, there are several factors to consider. You need to think about things like cost, style, and durability. Determine the design appeal and effect you would like the window or structure to have. For instance, you may want to consider the style and age of the building, its location, whether it’s a new build or renovation, and what the window or structure’s function will be. All these factors will help direct you to a suitable Muntin or Mullion and design type.
Factors to Consider When Selecting Muntins or Mullions
There are many factors to consider when choosing the perfect Muntin or Mullion for your architectural design. It’s essential to select the materials that are best suited for your application, whether it be wood, metal, or vinyl, and analyze their cost-effectiveness and durability. When designing, you’ll also need to consider the compatibility of the Muntins or Mullions with the existing architectural style of the building. Aesthetic appeal should be taken into account when selecting the right design and style, and once these factors are taken into consideration, you would ultimately select the best-suited design for your project.
Another important factor to consider when selecting Muntins or Mullions is the energy efficiency of the window or structure. The type of Muntin or Mullion you choose can affect the insulation and energy efficiency of the window or structure. For example, if you choose a design with a lot of small panes, it may not be as energy-efficient as a design with larger panes. It’s important to consider the climate and weather conditions of the building’s location and select a Muntin or Mullion that will provide the necessary insulation and energy efficiency for the building’s needs.
Muntin vs. Mullion: Which is More Suitable for Your Design?
The choice of Muntin or Mullion is ultimately based on functionality and style. While one may serve a primarily aesthetic purpose, the other may serve a structural one. It’s always essential to select the element that will provide the most stability and support for your architectural design.
Pros and Cons of Using Muntins or Mullions in Your Architecture
Both Muntins and Mullions have their pros and cons when it comes to their use in architecture. Muntins can create an illusion of separate panes without the need for multiple windows and are historically accurate in design. They can be difficult to maintain in terms of cleaning, and considerable amounts of time are required to clean each pane. Mullions, on the other hand, can offer structural support and distribute weight evenly, but it may also obscure the view from windows.
Another factor to consider when choosing between Muntins and Mullions is the cost. Muntins are generally less expensive than Mullions, as they are primarily decorative and do not require as much material or labor to install. Mullions, on the other hand, require more material and labor to install, making them a more expensive option. However, if structural support is necessary for your design, the added cost may be worth it in the long run.
Enhancing Your Building’s Aesthetics with Muntins and Mullions
When used correctly, Muntins and Mullions can be an integral factor in enhancing the aesthetics of an architectural structure. Muntins can create a sense of proportion and add historical character and texture to windows and panels, while Mullions can have a significant impact on a building’s scale, depth, and depth perception. With the right material selections and installation techniques, Muntins and Mullions can elevate the design of any architectural project.
Creative Ways to Incorporate Muntins and Mullions in Your Design
With the freedom and creativity that architectural design allows, there are endless ways to incorporate Muntins and Mullions into your design. You can play around with different shapes and designs or use a combination of both Muntins and Mullions to create new and innovative fenestration arrangements. The possibilities are endless and limited only by your imagination.
In conclusion, Muntins and Mullions are crucial architectural elements that serve both aesthetic and functional purposes. Understanding their unique properties and functions can help an architect or designer to make the right design decision. By using Muntins and Mullions to their fullest potential, you can create beautiful, functional spaces that prioritize aesthetic appeal and structural support in equal measure.

A drainage swale is made by moving and grading soil on your property to provide for the natural movement of surface water. If your unsure of yourself contact a local landscaper. It is hard work and done incorrectly could cause more damage than cure. In extreme cases an engineer may be consulted.
Are you sure you need to do a swail and just not installed drainage?
Rita – posted 23 March 2008 10:11
Thanks for your information. Folks who claim to know, say we need a swail. Installed drainage isn’t working due to the incline of the lawn. Have you ever heard of a precast swail? Again, thank you.

The swale is normally not cast and is normally a passive depressed area created by shaping the earth to create a shallow basin for sufficient retention and infiltration of water to protect surrounding improvements including but not limited to buildings and roads. The shape, location, and size of the swale depends on infiltration and percolation characteristics of the specific soil, the expected rainfall intensity, and the layout of surrounding including other existing swales and water bodies as well as improvements.

| The Sub-Sea Hydrojet Rock Trenching System|
The Miah Underwater Rock Trencher is a high production Trenching
System and a dramatic improvement over present conventional methods of excavating rock in the ocean floor for purposes of burying pipelines, submarine electrical cables, fibre optic cables, etc. Present subsurface excavation methods in solid rock include dredging, ripping and blasting,which in many cases extensively disturb the biological environment in which they are utilized.
One major objective in developing The Miah Underwater Trenching
System included reducing environmental damage while subsurface
work is being accomplished and to be able to restore the ocean floor
to close as possible to its natural state. Another objective was to provide a ocean floor rock trenching system more efficient and productive than conventional methods.
The rock trenching sled is basically comprised of a hydraulically
driven cutter assembly mounted on a sturdy steel structured foundation
which is pulled along the ocean floor during operation by a barge on the surface and assisted by the Miah Powered Stabilizer Chassis tracking behind the cutter chain in the trench bottom. Power is supplied by a power unit mounted on the vessel through an umbilical to the rock trenching sled. The sled is equipped with a high pressure water injector system which removes overburden on top of the solid rock strata enabling the sled to sit on the rock surface.
|The rock cutter head trenches down into the rock from the rock surface. The Miah Trenching System is utilized in conjunction with a more conventional water injector unit which will clean the trench and lay the electrical cable and/or pipe in a separate operation. Water currents will carry sediments into the trench to cover the utility and keep it in place. The well defined ditch configuration produced by the rock trencher will perfectly confine the cable or pipe protecting it from drift, iceberg scouring, dragging anchors and fishing gear. The actual trenching activity will take place within the housing of the sled which will confine the sediments keeping the surrounding environment from being disturbed.|
This system can be utilized with the Miah Prefatigue Trenching System with the Powered
Trenching subsea using our Ultra-Wide trenching system in tidal zones, beach landings or shore crossings in less then 4 meters of water depth without a support vessel. See Video Due to the modular design, it is capable of trenching in water depths of 80 meters with a support vessel.

EV Infrastructure Planning
The adoption of electric vehicles (EV) across America presents an exciting new challenge for communities, businesses, high-traffic interstate corridors, and multi-unit housing owners. It’s time to grow the momentum of implementing a much greater quantity of charging infrastructure to support EV owners and the rate of adoption. Of course, a growing rate of implementation presents a long list of challenges to address.
Public surveys continually identify the lack of public EV charging stations as a major deterrent to adoption rates. But America doesn’t just need more charging stations – we need them in the right places.
One of the most important things we’ve already learned from early adopters is that many of the existing EV stations were installed in the wrong places. This problem has the potential to be just as detrimental to EV adoption rates as a lack of infrastructure in the first place.

Spain considers sustainable urbanization
The Underground City 2012 Forum in Saint Petersburg from 27 to 29 June 2012, was a major event of its kind, aimed at drawing the attention of policy-makers, professionals, and the general public to underground space. The Forum theme, Use of Underground Space as a Public Policy Tool for Sustainable Urbanization, is important for Russia and the world, representing a blend of traditional underground construction issues and different public policy agendas, including sustainable urbanization, socio-economic development, social cohesion and the environment.
The forum gathered more than 400 participants, representing a variety of professional domains including government bureaucracy, parliament and law, city planning, architecture, economics, the environment, engineering and technology. It offered a one-day plenary session with a concurrent exhibition of urban underground projects and five concurrent technical tracks canada goose black chilliwack parka store the second day comprising city planning; law; environment and energy; technology; and education. Four technical tours were offered canada goose black chilliwack parka store the last day.
The event was organized by the Association of Underground Builders, which is a non-profit self-governing organization that, according to Russian legislation, has a right and duty to draft norms and standards for respective industries. Director General of the Association and Forum Director Sergey Alpatov, sees his role as more comprehensive, “realizing the full potential of industry and underground space itself, in terms of creating sustainable and livable cities”.
The forum, backed by the Russian Ministry of Regional Development and the Saint Petersburg city authorities, also enjoyed the support of the International Tunnelling and Underground Space Association (ITA), which was represented officially by Oliver Vion, its Executive Director, who gave a keynote address on Underground Space in Megacities. Han Admiraal and Antonia Cornaro, of the ITA’s Committee on Underground Space (ITACUS), gave lectures on global challenges for urban development and planning issues related to underground space.
The Forum offered a comprehensive discussion on the benefits and concerns related to urban underground space use, featuring such eminent scientists as Prof Aurele Parriaux of EPFL of Lausanne, Switzerland; Prof Ray Sterling of the Associated Research Centers for the Urban Underground Space (ACUUS); and Prof Andrew Whittle of MIT, Cambridge, USA. Scientists and experts from 15 countries were present at the forum. Among invited talks were presentations by researchers from the Delft University of Technology in The Netherlands (Dr Frank van der Hoeven) and the University of Birmingham, UK (Dr Ian Jefferson), who covered master planning and future research into underground space.
The historic city centre of Saint Petersburg is a UNESCO site of World Heritage and includes the renowned Hermitage Museum and hundreds of other important and iconic buildings and sites that impose special requirements for any new development. Coincidentally, the 36th session of the UNESCO World Heritage Committee was held in Saint Petersburg during the same period as the forum.
The Russian Government, at a very top level, has been always cautious about major development projects in the city centre. In fact, city laws restrict the height of new buildings. This leaves underground space as practically the only available place for new facilities and urban infrastructure. This approach was adhered to during construction of a new stage for the famous Mariinsky Opera Theatre. There is a 18m deep x 180m long x 70m wide underground space beneath the new building which is due to open just before Christmas this year (2012).
The proposed Orlovsky highway tunnel under the River Neva in Saint Petersburg is of particular significance to the international tunnelling industry. It will employ the world’s largest diameter TBM at 19. 25m, currently on order for design and supply by Herrenknecht AG of Germany. The project was discussed widely during the forum, and from a variety of perspectives.
The project dates back to the 1990s, when a need to connect the banks of the Neva was identified. A feasibility study and consideration of several design options followed. The most recent option is for a 6, 959m tunnel, including the 942m under-river section, to be built using the giant TBM. The tunnel would have two decks of three traffic lanes each, enabling an estimated transit of 60, 000 cars per day. The project would be executed as a public private partnership (PPP) through the Nevskaya Concession Company. There is, however, some doubt about the future of the project. City Governor Georgy Poltavchenko, on more than one occasion, has expressed his strong concerns about the project cost: estimated at about €2. 7 billion.
Overall, the forum highlighted the need for strong professional expertise and vision for urban underground space in Russia. Some presentations, by highly ranked bureaucrats from the Russian regions and from Saint Petersburg itself, exposed a lack of understanding for what urban underground infrastructure actually is. Confusion among decision-makers of different ranks was particularly visible when addressing issues of construction risk, and what these risks actually are in relation to modern state-of-the-art technology.
Further challenges lie ahead for city planning. Jury Miterev, the Chief Architect of Saint Petersburg, criticized developers and engineers for a lack of vision and a tendency to propose standard projects that lack imagination and that are not in keeping with the future development of such a unique city. Sharing the city of Moscow experience, Vladimir Korotajev from the Central Research and Design Institute for Urban Planning, reported a booming development of standalone underground facilities – such as parking garages and commercial space – but a lack of cohesive pedestrian networks or integration with existing public transport infrastructure and the city’s metro.
There was a strong call by many experts to maintain cohesion of the urban environment, including calls to avoid major traffic routes cutting communities and municipalities in half (Vladimir Korotajev, Russia, and Dr Frank van der Hoeven, The Netherlands). Prof Andrew Whittle (USA) called for the revitalization of urban communities, while Prof Xiao-Zhao Li (China) called on authorities to provide more public space. Developing this theme, Olivier Vion pointed to concrete examples of how urban underground space can provide solutions for tackling urban problems. Prof Sterling and Antonia Cornaro expressed strong concerns about the need for developing plans for underground space use, including three-dimensional masterplans.
In essence, the forum highlighted the opportunities that underground space can provide to improve urban life. Implementation of these opportunities seems to be close at hand, at least in key Russian cities where severe traffic congestion problems, caused by recent booms in private car ownership, leave little alternative other than to develop public transportation and underground infrastructure. Significant business opportunities exist in motor transport infrastructure using public, private, and PPP project finance models. Comprehensive use of urban underground infrastructure in public policy, however, seems somewhat distant; the management of urban sustainability through the utilization of underground space remains principally in the theoretical realm for the time being.
Dr Joan Clos, Executive Director of UN HABITAT, and former Mayor of Barcelona, Spain, visited Saint Petersburg recently on another occasion, and strongly advocated maintaining dense urban communities, as canada goose black chilliwack parka store has proved successful in generating wealth and saving energy. Widely known and accepted, the Compact City concept enjoys a consensus of opinion that a high quality of life, in a high urban density environment, is only possible with the existence of comprehensive underground infrastructure – a principle resolution agreed upon during the forum.

MISTRAS has been providing bridge monitoring and testing solutions since 1972, partnering with DOTS, FHWA, Engineering Firms and Universities to provide the right NDT solution for your application.
For over 30 years, MISTRAS has been aware of the rising demand to ensure structural integrity of bridges. Since bridges usually require more than the typical visual inspection, the additional information obtained from our monitoring solutions can provide input to authorities, and assist in making informed and effective decisions with regard to planning for maintenance, repair, rehabilitation or replacement. In addition, On-line Monitoring and Sensor Fusion can cover failure mechanisms, including unpredictable deterioration.
Hands-on inspection of suspension bridge cables is a costly (several millions of dollars) and time consuming process, requiring removal of the wrapping wire, paste and wedging of the cable. However, this inspection process only allows for approximately 2-3% of the wires to be inspected; counting the number of broken and corroded wires and then using statistical analysis to estimate the total number of corroded and broken wires within the panel to assist in the determination of the remaining cable strength. MISTRAS’ solution is a Structural Health Monitoring (SHM) system that uses Acoustic Emission (AE) for the detection of wire breaks. MISTRAS SHM systems monitor the cable 24 hours a day 7 days a week with real-time data processing, analysis, location and alarming, and can provide bridge engineers and owners with the information they need for informed decisions and better resource management of funds, personnel, maintenance, repair or rehabilitation.
Cable Tendons are a critical component of bridges and inspection of these cables is a costly and time consuming process. Improper grouting, sheathing, overstress during construction, weather induced vibration, corrosion and fatigue are just a few issues that have lead to wire breaks and subsequent failure of the tendon in new and relatively young cable stays. Our solution is installing an Acoustic Emission Structural Health Monitoring (SHM) system during installation or after the tendons have been installed for detection of potential wire breaks. Our SHM systems monitor the cable 24 hours a day, 365 days a year with real-time data processing, analysis, location and alarming and can provide bridge engineers and owners with the information they need for informed decisions and better resource management of funds, personnel, maintenance, repair or rehabilitation.
MISTRAS systems have been on suspension and cable stay bridges for over 10 years. In 1972, we performed our first bridge cable test on a bridge in California, where cables on the lift-span were tested for fitness for service. Since then we have installed AE systems on suspension bridges in Philadelphia, New York City, Virginia, England and other parts of the world to monitor, record, interpret, identify and report wire breaks and other activities. In addition, we can also perform remote diagnostic checks, maintenance and remote-calibration to maintain the operation and performance of the systems.
Acoustic Emission is used extensively to detect, locate and quantify cracking in steel bridges. Experience gained in the lab and over 30 years of testing oil and gas steel structures assist us in the routine application of assessing steel bridge structures both globally and in local locations to check for the presence of steel cracking. Tested and approved by FHWA and other international agencies on defects identified by inspection and on subsequent repairs, AE is a power tool for bridge inspectors. MISTRAS also has hundreds of experts in x-ray, magnetic particle and other traditional NDT technologies.
MISTRAS has used Acoustic Emission, Ground Penetrating Radar, Impact Echo and other technologies to assess concrete. AE can detect tendon breaks in concrete beams, cracking caused by rebar corrosion and fretting from crack surfaces, and is still being used in research to hear if concrete has matured.
It doesn’t take explosives to bring an aging bridge to failure. In 2006, a main tendon on a cable stay bridge was nearly severed. The problem was detected before it became critical but only after $2 million in damages had already been incurred. The bridge was instrumented with our proven system and provides alarms to authorities, in real-time, if various acts of vandalism are in progress. Bridges, dams and other structures can be monitored with single or multiple sensor technologies to detect problems before they happen.


Hermes, Netburn, O’Connor & Spearing, P.C. represented a major general contractor/construction manager in a case involving delamination of paint on the crown of a major metropolitan office tower. The firm assisted the client in negotiating with the owner to make arrangements to perform the removal of the paint from the exterior of the structure and to repaint the crown without interfering either with the occupancy of the tower or the surrounding neighborhood.
At the same time, Hermes Netburn retained experts to study the cause of the delamination of the paint and, after those studies, brought a civil action against the steel supplier whose failure to cure the painted steel properly resulted in the delamination. The subcontractor’s surety was also a party in the case. After defeating Motions for Summary Judgment by the subcontractor and the surety, we obtained a settlement in the case that, with other reimbursements available to its client, resulted in recovery of substantially all of the expenditures by the client. Additionally, the client retained the good will of the developer of the project and subsequently was awarded substantial contracts for the construction of other projects.


Steel frame knock-down house or prefabricated house There are various usage patterns. From shop kiosks, guard towers, offices, coffee shops, temporary residences, permanent home building From small to large. This gives foundations a variety of forms as well, from temporary foundations to permanent foundations, but the more popular ones are
Concrete foundation laid on the ground (slab on ground) Due to the ease of construction, the price is not very high. and easy to install But it should be the ground, hard land and filled for not less than 1 year. Soft soil and new soil should be piled up to help support the weight.
Note : We are a house building company. We have been a well-known company in the home building business for a long time. We have more than 5000 houses built in Thailand. find more information on our website : https://www.trendyhome.co.th/
For example, concrete foundations are laid on the ground.
The thickness of the concrete floor is 10-15 cm., depending on the form of use.
- In the case of building a knock-down house on a concrete base or using a crane to lift and place, use a thickness of 10-15 cm.
- In the case of installing a A transport truck with a house is installed on a concrete base using a thickness of 15 cm. as standard.
Concrete slab laying on the ground (slab on ground)
- Ready mixed concrete, compressive strength 240 KSC.
***The emphasis should be on standard cement plants only.
- Wire mesh sieve, size 20×20 cm., thickness 4 mm., padded with mortar to help the sieve not sink or float. standardize the work
*** Should design a concrete floor. Spreading out from the house 1 meter on each side, it will protect the ground from subsidence well and when it rains, the soil will not splash onto the messy house.
Example: hard soil + compacted rock Pouring concrete into a large courtyard Allows easy installation, easy to move.
Example: footing house foundation, size 60x60x60 cm.
Ready mixed concrete, compressive strength 240 KSC.
The foundation footing rebar RB9 is suitable for small buildings. Build a house that weighs 3-4 tons and place it on solid ground. Or a knock-down house that is built on the job site without moving to install, helping to support heavy loads and prevent collapse. Because digging the soil deep, about 70 cm.
Work requires planning. Finding the location of the steel plate foundation To use it must be sprinkled with stones. or more turf because when it rains The soil will splash and stain a messy house.
temporary foundation set on solid ground
Cast a RB9 reinforced concrete slab, size 60x60x15 cm. and bring the house to set up. on the slab For foundation work, field offices, shops set up on leased land, or knock-down houses that need to be moved later within 3-5 years.
Knock-down house foundation with low budget Most of the people use this type of foundation to reduce costs, which in the beginning may not have a subsidence problem. But when the soil is eroded by rain for many years, there will be more or less problems with subsidence.
Collapse causes problems with doors that are difficult to open and close, or the bathroom floor, water does not flow down, drain grates. due to the slope
Spreading foundations for small and large permanent residences
Knock-down house foundations for small permanent residences and for building large houses with a height of not more than 1 meter, who do not want to have problems with the house subsidence, should be spread foundations, which are qualified to Very good load-bearing for hard soil areas. Enough for a steel structure building with fiber cement walls
- In the case of a soft soil area, piles should be placed. to gain additional weight (Should consult an experienced engineer)
- In the case of a building raised above 1.5-2.5 meters, additional ground beams and piles should be added in the next order depending on the weight of the soil in that area. should consult an engineer experienced)
Example of foundation work for a large permanent residence
Ready mixed concrete, compressive strength 240 KSC
Example: The foundation of a fiber cement steel frame house for permanent residence with a height of 2 meters.
Footing-type foundations: short piles are made, ground beams are made, cast iron is tied to the pillars to be lifted to a height of 2 meters, and the ground is poured around the area. high budget
But there is an advantage that the area below can be added more It can be a kitchen and a garage.
steel needle foundation
Steel needle is a dry foundation system. weight-bearing screw Can be installed and dismantled very quickly, which steel needles have models from
- Small size, 80-100 cm long. For work with less weight 300-400 kg.
- Large needles and 2-3 meters long for heavy weight 3-4 ton.
Suitable for small knock-down houses large single storey Can be installed in a narrow space well.
ISOWALL wall, a hot alternative material
Isowall is a prefabricated wall and roof panel. It is made of color coated steel sheet with EPS foam on both sides. Light weight, easy to install, no need to make a rough frame, no need to paint. It has built-in insulation.
Most of them are used in the cold room, clean room or field office industry.
The standard width is 1.2 meters.
The popular thickness is 2 inches, 3 inches thick (some factories are 1 meter wide).
As for the length, we can set the factory to cut. like a metal sheet roof, for example, need a length of 2.5, 3, 4 meters
- 2 inch thickness sheets are used for wall applications. The height does not exceed 2.6 m.
- 3 inch thickness sheet will be used for roofing or wall work with length or height not exceeding 4 m.
Installing the isowal by designing the reinforcing structure of black angle steel L50x50x3 mm. and fastened with rivet nails
- Keeping the edge of the sheet with aluminum U 2 – 3 inches.
- according to sheet thickness
- Wall corner and interior ceiling corner with 1.1/2 inch aluminum screen.


Chetham’s School of Music
Our experts were appointed as Project Managers by the world famous, Chetham's School of Music to assist in the development of a new accommodation block and Conference Centre on an adjacent site.
The site was archaeologically challenging. The original site is medieval, which later developed into an old bombsite, this required two phases in the development of the site.
The two phases; cleaning and constructing took twelve months. The complex was initially built as accommodation for the school, but also had to be built to provide a commercial conference centre.
Our team were responsible for developing the brief for all the project requirements from the design process, through to the appointment of consultants. They also managed the construction through to completion. The project was delivered to the client on time and on budget.
