Each report component is first presented with a general description related to the specific component and then a unique analysis for the property of interest.
Local municipalities (cities/counties) often divide their communities into different areas or zones. Each zone category typically dictates what type of development can occur. For example, a zone might be designated as single use where residential type buildings can be constructed. The zone designation might also indicate the lot size or the building scale that is allowed at that location.
Topography and Terrain
No Flood Florida relies on the most up-to-date digital terrain information that is derived from LiDAR technology. For a given property of interest, we will display the digital terrain model along with 1-ft contours to help better understand the slope of the land.
National Wetland and Flowline Features
Wetland and flowline data are incorporated into the Land Due Diligence Report to help better understand potential hazards when developing a piece of land. Often, wetlands are protected from development pressures.
FEMA Effective Floodplains
The current FEMA Effective Floodplain maps are used to help determine development capabilities and potential issues with mitigation. Additionally, the presence of the high-risk floodplain on a property could trigger flood insurance requirements. Below is a brief review of the different flood zone designations:
- High Risk Zones
- Zone A – These areas are similar to the 100-year floodplain, with the exception of not having an engineering model establishing the Base Flood Elevation. Homes in these areas are typically required to purchase flood insurance.
- Zone AE – These areas are subject to inundation by the 100-year storm event. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are established. Mandatory flood insurance purchase requirements and floodplain management standards apply. No Flood Florida further breaks down the Zone AE floodplains into AE, LEVEL POOL and AE, RIVERINE. An AE, LEVEL POOL flood zone indicates a none-flowing system, while the AE, RIVERINE designation defines flood zones that are associated with flowing systems.
- Zone VE – These areas are subject to inundation by the 100-year storm event with additional hazards due to storm-induced velocity wave action. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are established. Mandatory flood insurance purchase requirements and floodplain management standards apply.
- Moderate Risk Zones
- Zone X, shaded – These areas are subject to inundation during what is called the 500-year storm. The 500-year storm has a 0.2 % chance of happening in any given year. This happens less often than the 100-year storm. Homes in these areas typically are not required to purchase flood insurance. No Flood Florida defines this zone as X, 0.2 PCT ANNUAL CHANCE FLOOD HAZARD with a BFE of None.
- Low Risk Zones
- Zone X – The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood (500 year flood), are labeled Zone C or Zone X (unshaded). No Flood Florida defines this zone as X, AREA OF MINIMAL FLOOD HAZARD with a BFE of None.
Soils data were downloaded from the United States Department of Agriculture (USDA) Soil Survey website. Through additional processing, No Flood Florida is able to report on the hydrologic soil class, the frequency of flooding, and the ability of the surrounding soils to infiltrate water.
Landuse data are often produced by local/state agencies. These geospatial features convey the type of landuse for a given area. Some examples might be Residential, Industrial, Commercial, etc.
Often, local communities and governments provide general coverages for utilities that No Flood Florida can visualize on a map. The utility coverages often define various municipality services like water and sewer.

A tower constructed at hub height or higher costs more than twice that of a short tower. The geometry of a meter tower is cheap and simple: it’s a tall pipe with lots of guy lines. An meter tower is a climbable, guyed tower with a large, poured concrete base – and that simply costs more. Field measurement data on wind velocities and wind-induced acceleration responses at the top of the m high Shanghai World Financial Center (SWFC) under normal climate conditions are studied. Characteristics of the mean wind speeds and turbulence intensities, gust factors, power spectral densities, and turbulence integral scales of the fluctuating wind speed are analyzed in different.

In general, the higher the tower, the more power the wind system can produce. The tower also raises the turbine above the air turbulence that can exist close to the ground because of obstructions such as .


This detailed technique is often used to complement magnetic gradiometry surveys or, depending on the project objectives and nature of the survey area, as a survey method in its own right.
An earth resistance survey measures variations in the electrical resistance of the ground using an array of stainless steel electrodes. The pattern of resistance variation indicates variations in the sub-soil due to its moisture retention and/or mineral properties. This variation can be interpreted to indicate the presence or absence of sub-archaeological surface features.
The technique can be deployed using fixed-spacing, hand-portable or cart-mounted electrode arrays depending on the nature of the survey area. The depth of investigation is largely dependent on the electrode spacing and the nature of the soils and can be up to 1.5m depending on the type of electrode array used.

On October 30, the City of Fremont and Kaiser Permanente unveiled the designs for Vision Zero traffic safety street banners that will be displayed in Fremont through the end of 2020.
Approximately 150 banners will be installed along Fremont Boulevard, a key corridor that is traveled by more than 25,000 people every day. The five banner designs, which were designed by City staff, focus on educating the community about behaviors that data driven analysis indicates are high risk factors in Fremont: unsafe speeds, failure to yield to pedestrians, driving under the influence, and inattentive driving. The project is supported by a $25,000 Kaiser Permanente Northern California Community Benefit Program.
In the past three years following adoption of its Vision Zero program, the City has reduced major traffic crashes by fifty percent. That is in an environment where nationwide pedestrian and cyclist fatalities increased from 2017 to 2018. The City’s accomplishments since 2015 include upgrading all 16,000 street lighting with brighter LED streetlights; installing pedestrian countdown signals at all 220 traffic signals; restriping more than 50 miles of roadways with better bikeways and to promote safer speeds; enhancing more than 10 crosswalks with pedestrian signals and flashing beacons; and delivering 300 safety improvement projects near schools.
Karen Tejcka, Chief Operating Officer and Chief Nursing Executive for the Kaiser Permanente Fremont Medical Center stated in her remarks, “This critically important campaign directly aligns with Kaiser Permanente’s focus on Total Health that goes beyond our members to include the communities that we serve.”

Titanium has been used in construction for 40 years. It is currently used in buildings in Japan, the United States, China, the United Kingdom, Scotland, France, Germany, Spain, Holland, Belgium, Switzerland, Sweden, Canada, Peru, Singapore and Egypt. titanium. In terms of titanium used in construction, in addition to roofs and curtain walls, there are also building walls, decorations, sculptures, monuments, etc. The application of titanium in the field of construction has successfully solved the corrosion problems of many coastal buildings and has also provided titanium with It opens up new application areas in the construction field.
Titanium as a decorative material has the following main characteristics:
(1) Light weight, good strength and not easy to rust;
(2) Color can be adjusted and controlled as needed:
(3) Easily matched with other materials. Focused use can increase added value.
In terms of titanium for construction, Japan is in a leading position and built the world's first titanium roof (Hayasuihime Temple) in 1973. 1995 was the heyday of titanium for construction in Japan, with an annual titanium consumption of 294t. Japan has mature technology in this area, has accumulated rich experience, and has accepted orders from abroad. The current market size is about 200t/year. Nippon Steel Corporation of Japan produces titanium building materials with high quality and unique design based on its excellent cold rolling and surface treatment technology.
In order to promote the application of titanium in the construction field, the American Timet company not only provides a variety of products, but also offers a 100-year quality guarantee. In October 1997, Timet provided 80t of exterior decorative titanium plates for the outer walls of the Guggenheim Museum in Bilbao, Spain, becoming a pioneer in the use of titanium in European and American construction. Titanium was selected for the roof of Abu Dhabi Airport in France, and the amount of titanium used in the structure reached 800t. The airport is the first example in the world of using titanium as a building structural material. The outdoor cafe in the Conde Nasta corporate building in New York uses 5t titanium as its interior decoration.
The first large-scale building in China to use titanium was the Hangzhou Grand Theater. Later, titanium metal plates were used in the metal curtain wall of the roof. More than 6,000 industrial pure titanium plates were used, weighing I60t. The central building of the National Center for the Performing Arts in Beijing has a unique shell shape, and its surface is cleverly spliced by 18,398 titanium plates and 1,226 ultra-white glass. Titanium is chosen as the cladding of the metal plate for the round arch. The roof structure from the inside to the outside is: steel structure oval shell, sound insulation layer, thermal insulation layer, waterproof layer, and exterior decoration layer (made of titanium from Nippon Steel Corporation of Japan). Composite panel roofing), the total area of titanium cladding is 36,000m2, using titanium material 60. The completion of these two projects has greatly promoted the application of titanium in my country's construction industry.
China's use of titanium in the construction field first started in the Baoji High-tech Zone, where a titanium sculpture with a titanium droplet symbol was installed in the district's fountain. In 1987, the titanium sculpture "Dolphin and Man" made in Baoji was placed in Baoji Riverside Park. Two years later, the same titanium sculpture "Dolphin and Man" was produced for the Beijing Institute of Oceanography. In 1999, a large-scale titanium sculpture "Qiankun Ball" was designed and manufactured for the Xingtai City Center Square. It is 6 meters high and is entirely made of titanium. The amount of titanium used is about 2.5 tons. In April 2001, a large-scale titanium sculpture "Rooster Crowing" was built, adding a new landscape to the pedestrian street of Baoji City. The overall height of the sculpture is 8.2m, the chicken wings are 1.8m long, and it weighs more than 2 tons. Due to the use of nitriding technology, the surface appears golden yellow.


In a boundary survey, we develop evidence as to the location of one or more property boundary lines. Then there are a number of options available, per the client’s request. We can flag existing boundary monuments, mark the property line and/or reset any missing monuments.
Boundary Line Adjustment
In a boundary line adjustment, the common line between two adjoining parcels of land can be adjusted, or changed, subject to approval by the relevant governmental jurisdiction, as long as no new parcel is created.
Minor Land Division
This is the division of one parcel into several parts. The rules governing Minor Land Divisions vary with county and municipality in Arizona, so it is necessary to check with the governing jurisdiction prior to commencing a project such as this.

Popular Bridges in The World
The world is full of spectacular attractions, whether they are nature’s creation or man-made architectures. In general, people find natural beauty or architectural marvels more attractive, but there are some other things that are even more impressive, like Bridges! As a matter of fact, bridges are the most incredible architectural wonders, which have joined remote places in the world (easily accessible). Since ancient age, bridges are the inevitable part of our life. Once used to be a mode of commutation, today some bridges make the best travel destinations. In fact, in some cases, the city is recognized and celebrated for its magnificent bridges. Read on to this write-up and know about some popular bridges of the world that are also a famous tourist destination.
Accurately translated as “the old bridge”, Ponte Vecchio is one of the most spectacular bridges of Florence, Italy. The bridge was built across the Arno River (during the medieval period) and portrays rich history dating back to the time of the Romans. As a matter of fact, it is Europe’s oldest stone closed-spandrel segmental arch bridge that has survived the World War II. In addition, the most special thing about this bridge is that, it has shops of jewelers, souvenirs and art dealers built into it. If you are planning a tour for Italy, do the flight bookings with EaseMyTrip.com and get cheapest deals.
Golden Gate Bridge, USA
A unique architecture of the United States, Golden Gate Bridge is somewhat a symbol of San Francisco and California. This gargantuan bridge is named so because it spans the Golden Gate Strait between Marin Country and San Francisco to the north. In fact, it is known to be the world’s one of the longest suspension bridges. The bridge colors with typical orange color to enhance visibility during heavy fog. This magnificent masterpiece was designed by Joseph Strauss, Charles Ellis and Irving Morrow, took seven years to build and completed in the year 1937.
Straddling over the valley of the river Tarn, the Millau Viaduct is a beautiful cable-stayed bridge located close to Millau in southern France. With a height of approximate 343 meters (which is slightly higher than the Eiffel Tower), it is known to be the tallest vehicular bridge in the world. This wonderful bridge is designed by Michel Virlogeux and Norman Foster and is constantly being ranked as one of the great engineering achievements of all time. Extending around 8,071-ft in length with the longest single extent of 1,122-ft and a high clearance below of 886-ft, this gigantic bridge offers jaw-dropping views of the valley.
Tower Bridge, London (United Kingdom)
A symbol of London and one of the most iconic identities in the United Kingdom (UK), the Tower Bridge is a combined bascule and suspension bridge which is built across the river Thames. This magnificent bridge gets its name from the Tower of London because it is located in the vicinity of the tower. The construction of the bridge was begun in the year 1886 and took eight years to complete. Built on piers, the bridge is 800 feet (244 m) in length with two towers, each 213 feet (65 m) high. The central span of 200 feet (61 m) between the towers is split into two equal bascules or leaves that can be raised to an angle of 86 degrees to allow river traffic to pass. With such great architecture, the bridge is one of the significant tourist destinations of London.


Elevations Studies for Buildings, starts with the generic concept of how we want the building mass to work. We are thinking about the forms and the shapes, and about how the space around the forms is going to work. Questions like: How does the approach to the house feel? – or – What sort of living spaces will be a part of this view? are the considerations for how the building massing will work and what sort of views we want to create from within the house. Other than that, the initial floor plan concepts are about getting the programming, room sizes, and adjacencies correct.


Europe is rich in its history and buildings reminding its culture and time periods. It's a shame that they do not always receive appropriate protection and care which they merit as a part of our history.
Restoration not only has to renew the aesthetic view but also reduce the usage of energy, to improve the climate of the premises, to enlarge the value of the buildings and improve the quality of life.
Water is considered to be the source of life on earth but at the same time it is the reason No 1 of all defects occurring in the building constructions;

Manama, Jan. 14 (BNA): Works, Municipalities Affairs and Urban Planning Minister Essam bin Abdulla Khalaf has inspected the expansion of Wali Al Ahad Highway, where a progress of 60% has reportedly been achieved.
During his visit, Roads Construction Chief and Engineer in Charge of the Project, Fathi Al Farei, briefed the minister about the latest progress achieved in the project, which presently involves implementation of storm water drainage network on both directions, civil works, reclamation and laying of asphalt at some parts, construction of side pavements and construction of concrete wall along the central reservation.
The minister extended thanks to all concerned service entities for their collaboration with the Ministry, stating that the biggest challenge that faced the Ministry was the transfer and protection of services, especially high voltage ground cables. Most services were successfully transferred, which will positively affect progress in the project.
The BD1,969,265 project was earlier awarded to Eastern Asphalt & Concrete, and comprises of expanding the highway to three lanes at each direction and revamping all intersections along the highway, in addition to re-constructing the highway infrastructure, constructing brick pavements, implementing a storm water drainage network, lighting, signage and protecting the existing services.

Does my Bay Window Encroach onto City Property?
Oh no, does my bay window encroach onto city property?
Whether it’s a bay window, porch, retaining wall, or other projection, surveys often reveal what appear to be encroachments, or structures built beyond the property beyond the property boundary line. Most often, these are encroachments onto city public space. Not to worry, the District of Columbia has historically not only allowed such encroachments but has encouraged them through its construction code to enhance architectural diversity along the streets.
Public parking areas
The area between the property boundary line and the street is known as the “public parking” area and, while projections are permitted, homeowners are expected to maintain the area as if they were the rightful owners. The city established these “Public Parking” areas in 1872 to create green space beyond what was needed for the road and sidewalks and, within this area, enough space to allow for building projections.

In the construction industry, you will always want to find the best material for the job. One of the biggest debates in this industry is whether galvanised steel or stainless steel is the best material. The two may look the same at first glance but they are actually very different and which material you should use will depend on the application. This means that it is important to be aware of how these two materials differ so that you can always make the right decision when trying to decide between the two.
So, stainless steel or galvanised? Read on to find out eventing that you need to know.
Galvanised steel is regular steel which is dipped in a pool of molten zinc in a process known as hot-dipping. This adds a layer of zinc to the surface which is important because it provides a protective layer to the surface which will stop corrosion from occurring.
Despite this, galvanised steel is significantly weaker than stainless steel but this does make it the cheaper material. Additionally, the zinc coating will eventually wear away and if it is damaged it could suffer from rust. Although this can be a problem, any remaining zinc acts as a sacrificial anode which means that it can still protect exposed steel.
Stainless steel, meanwhile, is prepared by mixing regular steel with chromium when they are both in a molten state. The mixture hardens into a solid state as it cools when the composite is treated with acid which removes any impurities on the surface. The mixture with chromium means that stainless steel has a protective mixture which can prevent rusting for longer than galvanised steel which just has a protective layer.
Stainless steel is stronger than galvanised steel and retains anti-corrosive properties for longer but it is also much more expensive to purchase. This means that it is important to think about when to use this material over galvanised steel.
The best time to use galvanised steel over stainless steel is when there is minimal risk of damage to the metal. It is mainly used for smaller-budget projects and is often used for pipes, nuts, bolts, fasteners and in the manufacturing of air-conditioning equipment.
Due to the fact that stainless steel is more durable but more expensive than galvanised steel, you will see this material mainly used in larger and more expensive projects. It is regularly used in the construction of buildings, bridges, cars, railways, aeroplanes and hand tools. Stainless steel is also more resistant to salt so it is regularly used in coastal and marine environments too.
Galvanised steel and stainless steel may look similar when comparing the two materials but they are vastly different when it comes to preparation, composition, properties, strength and cost. It is essential that you are aware of what these differences are if you work in construction as this will help you to make the intelligent decision as to which material you should be using at different times.

The Sign-Off:- once the necessary paperwork has been drawn up and agreement signed, technical drawings will be produced and work will shift from the design studio to manufacturing plant.
The Site Survey:- shortly after sign-off, a site meeting will be called for. We ask that you, your electrician and your plumber are present at the meeting as critical water and electrical points will be discussed and marked. It is imperative that these markings be preserved in the period prior to site work to ensure a smooth and hassle-free process once construction work commences on the site.
The Site Management:- shortly after the site survey meeting, your Designer will advise you of the proposed installation date so that you and your contractors can schedule works for the preparation of your site. A week before the proposed installation date, your designer will assess site readiness before issuing final delivery instructions.


Hate those annoying potholes? You won’t like what’s coming with climate change
Whether you’re driving, biking, or simply enjoying walking on the sidewalk, potholes are annoying, dangerous, and expensive. So get ready – as the spring thaw begins in much of Ontario, pothole season begins.
Over the years, CBC stations have told hundreds of stories about pothole problems in areas of Ontario and across Canada. Rapid road deterioration is already costing Canadians an additional $3 billion a year in vehicle maintenance, according to the Canadian Automobile Association.
As such, we should all be concerned that climate change could wreak havoc on our streets as cities prepare for more potholes, bumps, cracks and ruts.
Thankfully, engineers are working to create better, more durable and environmentally friendly materials, with innovations like self-healing asphalt and roads linked to artificial intelligence (AI) technology that can help predict where cracks and potholes will appear.
The Great Lakes Climate Change Project is a collaborative initiative by CBC stations in Ontario to study climate change from a provincial perspective. You can read some of the latest stories from the project here:
Canadian climate is perfect for potholes
Canada includes many different climates, but it just so happens that many of them already provide ideal conditions for potholes in the spring.
“Any time [temperatures] start to fluctuate between above zero and below zero, especially if these shifts are large, it’s basically pothole season,” said Scott Berry, road and traffic operations manager for the city of Kitchener.
“Whether it happens in January as a short week instead of a cold, or whether it happens during the traditional pothole season in March, April and May, that’s what contributes to potholes to a large extent.”
This is known as the freeze-thaw cycle, and such cycles are common across Canada, said Ali Nazemi, assistant professor of civil and environmental engineering at Concordia University in Montreal.
Road problems occur when water seeps into the base under the top layer of asphalt and is subjected to freeze-thaw cycles. Water is the only known non-metallic substance that expands when it freezes and exhibits great strength in doing so.
When [water] expands, it starts to put pressure on the soil and infrastructure… it cracks the infrastructure,” Nazemi said. is happening, and the time is expanding.”
The more freeze-thaw cycles that occur, the more of these expanding ice-filled voids form under the top layer of asphalt and the larger they become.
“If this cycle continues, it will greatly increase the rate at which infrastructure wears out,” Nazemi said.
When it warms up and the ice melts, the top layer of asphalt will not be supported. When a truck or other heavy vehicle passes over the area, the asphalt can sag, exposing the void underneath.
And so a pothole is born.
Can potholes become a year-round problem?
Using new modeling techniques and data from remote sensing satellites, Nasemi was a senior author on a 2021 Journal of Hydrology article and a 2022 Nature Scientific Reports article that highlights some previously overlooked key climate change impacts in Quebec. He is currently applying these methods to the Canadian-wide model.
His study suggests that the transitional seasons before and after winter will become longer, meaning temperatures will approach freezing and the number of freeze-thaw cycles will threaten infrastructure across the country.
It’s a problem for cities and road users, said Scott Berry, city operations manager in Kitchener, Ontario.
“If that happens, then we will have a longer pothole season. It will not be limited to March, April and May. At some point, you might see pothole season creeping into February.”
There are many other ways that climate change will affect our roads, said Hassan Baaj, professor of civil engineering at the University of Waterloo and director of its Center for Road and Transportation Technology.
Extreme heat in the summer means more rutting as depressions in the asphalt are worn down by heavy truck tire marks. Increased rainfall can lead to flooding and damage to roads, while more intense exposure to sunlight degrades the quality of asphalt and leads to more cracks that water can filter through.
Of course, the best way to prevent additional damage to our roads is to reduce emissions. But since we’ve already experienced several decades of warming, researchers are looking for ways to mitigate the damage.
In fact, there is a “self-healing” asphalt.
Researchers have long found ways to produce “better” asphalt, Baai says, including changing the mix to make the asphalt more resilient, easier to produce, requiring less maintenance, or even self-priming.
“We are working to develop high-performance asphalt mixes that are highly resistant to various types of pavement wear.”
In recent years, sustainable design has become a major focus. This means that the innovations engineers explore must be sustainable and environmentally friendly.
As an example, Baaj cited “self-healing” asphalt, which is inspired by the biology of the human body.
There are numerous ways to do this. One involves introducing bacteria into the asphalt. When exposed to water, the bacteria produce calcium carbonate, sealing any cracks with limestone.
There’s also smart asphalt, artificial intelligence-driven roads that help predict and detect cracks long before they can be found on the surface, making repairs cheaper, easier, faster, and more efficient.
We have different tools built into different pavement layers. [and] transmitters that will collect data and send it to our team at the University of Waterloo for analysis using algorithms that we will create using artificial intelligence,” Baaj said.
“When we see patterns, when we see how things like high voltages and so on happen, we can connect those events that happen in the pavement and future events that happen later, like cracks that appear.”
Research is also underway to find more environmentally and climate friendly alternatives to traditional asphalt, which uses crude oil bitumen as a binder and is known to emit harmful air pollutants for years after installation.
A pilot project is under way in Thunder Bay in northwestern Ontario and several other cities in Canada to investigate the partial replacement of an alternative binder called lignin, a polymer mill, and abundant paper mill waste.
Baaj is also working to recycle old pavement to create new, more resilient asphalt without wasting old materials. He said it’s harder than you think, but it’s worth it.
“If we use recycled materials correctly, we will build sustainable roads that are as good as or even better than those that do not use recycled materials. Therefore, I do not create problems for future generations. My successors will have to deal with this. My kids will have to deal with this.”


Ceramic Coating Systems
Ceramic facade coating system; It is applied together with the carrier aluminum construction in the false parts of the buildings. Ceramic facade coating systems are preferred materials for interior and exterior facades due to their high abrasion and impact resistance, low water absorption, stain resistance, easy installation, resistance to external weather conditions, and many color and size options.
After the selection of the preferred ceramic or granite material in the system, heat insulation is provided on the false facades of the building, and the sub-carrier of the system is integrated into the building as an adhesive, clipped, hidden channel, polyurethane hanger, and multi-clip system on aluminum construction. Granite & Ceramic Facade Coatings are stain-resistant, are not affected by atmospheric changes and have a very high heat resistance. Ceramic Facade Coating Systems; Applied in five different methods to name them Adhesive, Clipped, Hidden Channel, Polyurethane Hanged and Multi Clipped.
Ceramic Coating Systems Catalog
Types of Ceramic Coatings
1. Mechanical Adhesion System
Another installation method of ceramic facade coating is adhesion. It can be applied smoothly on the exterior facades of buildings with a maximum height of 30 meters. The ceramics are mounted to the aluminum carrier profile with auxiliary temporary tape and a polyurethane-based material with high strength without losing its elasticity at -40 to +100. The joints can be applied as open or closed. It can be mounted with open joints or closed joints as per demand. In the Closed Joint System, in addition to the open joint application, special type aluminum profiles in the desired RAL color are mounted in the vertical and horizontal joints of the coating material and the gaps between the joints of the material are closed.
2. Mechanical Clip System
It can be applied on the facades of multistorey buildings. The porcelain tiles are mounted on clips that attach the vertical carrier aluminum profiles mounted on each vertical joint axis. It is an open joint system. Joints in the range of 4-8mm can be used.
The system not only protects all kinds of building facades against external weather conditions, but also saves energy with its application method that allows heat, water and sound insulation. It is an economical and reliable system applied by mounting the ceramics to the carrier aluminum profiles together with stainless steel visible clips and EPDM wicks. It can be used in all kinds of sizes.
Granite ceramic tiles, which have the desired performance characteristics in exterior facade coating materials such as high impact resistance and surface hardness, stain resistance, water absorption, zero atmospheric conditions, together with the advantage of lightness against natural stone coating materials, are assembled on their own special construction after the stone wool laid in front of the wall of stone materials of various qualities.
3. Mechanical Hidden Channel System
The clips, which are attached to the 4 dovetail-shaped channels drilled into the porcelain tiles, are mounted to the horizontal supporting aluminum profiles mounted on the vertical supporting aluminum profiles. Can be applied on the exterior facades of multistorey buildings. Minimum 4mm joint gap is used in the open joint. It is generally applied to materials with dimensions of 60×60cm, 60×120cm, 50×100cm. The system protects all kinds of building facades against external weather conditions and saves energy with its application method that allows heat, water and sound insulation. Ceramic facade coating system is one of the preferred materials for interior and exterior facades due to its high abrasion and impact resistance, low water absorption, stain resistance, easy installation, resistance to external weather conditions, and many color and size options.
4. Mechanical Polyurethane System
Can be applied on the exterior facades of multistorey buildings. Porcelain tiles are mounted to horizontal aluminum profiles by spraying polyurethane sealant and clipping. In this system, a caste is formed between the tiles on the vertical. Suitable for all sizes. Vertical joints are made into a closed system by applying 5 or 8mm aluminum joint profile. The system not only protects all kinds of building facades against external weather conditions, but also saves energy with its application method that allows heat, water and sound insulation.
5. Mechanical Multi Clip System
The ceramics are attached to quadruple multi clips mounted on the vertical carrier aluminum T Type Profiles. It is an affordable system that can be used in all sizes.

Individual and public passenger transport needs a new form that is environmentally friendly, sustainable, easy and quick to build, user-friendly and fast.
SKYEXPRESS allows installation on supports over the existing traffic routes or over land like a second traffic level. Inclines and descents up to 20° are possible. An unrestricted fast cabin sequence every second via switches and circular distributors in different directions for simultaneous scheduled and individual traffic guarantees highest flexibility and capacity.
Our mission is the future oriented development of mobility. There are loads of problems all over the world. But first and foremost the climate change motivated us to bring this project to a success. People all over the planet should be able to travel, move fast, eco-friendly and cheap. Now we want to find investors and interested cities which think the same way and are brave enough to realize this concept with us. This is now our challenge, which we are happy to take on.
Stops are always routed off the main line in a parallel rail, so that continuous traffic is never affected.
The cabins are electrically powered, fast and economical. Each cabin has its own control system, which reach the target completely autonomously. A higher-level, central control system controls and supplies the cabins with real-time information.
With the immediate cabin sequence and the district distributors in the rail network, a unique flexibility is created. The autonomous control system communicates with cabins in the immediate vicinity and coordinates itself, e.g. when entering circular distributors, through redundant sensors.
The system allows individual booking of cabins of any size. The individual passenger will book a cabin of 3, an entire company one or more cabins of 30 at the respective cost. There are no limits to individual use within the transport network and transport se-no-stop passengers from the start to the destination in such a short time, which cannot be reached by any other means of transport.
SKYEXPRESS relieves road traffic and thus significantly reduces exhaust emissions, noise, accidents, stress and time losses due to traffic jams. This is a forward-looking transport system that does not yet exist in the world, which takes passengers to their destinations faster, safer and more cost-effectively than any other means of transport.
Transport networks are constantly evolving. SKYEXPRESS is modular and can be changed and / or expanded at
With SKYEXPRESS, entire regions in the surrounding area of the city networks or neighbouring towns can also
be involved. For rural areas, individual solutions must also be built economically.
SKYEXPRESS can also handle inclines and gradients of up to 20°, which allows both use in hilly terrain and
lowering stops to road level.
SKYEXPRESS allows previously unthinkable logistics solutions for the transport of goods. The supply can come
directly from a logistic center or from a transfer station outside the city and is directed to the receiving station.
Flexibility is the basic principle of the SKYEXPRESS transport system. Stops can be adapted in a variety of forms
of expected user frequency at different levels.
The booking of a cabin and/or the purchase of tickets for the use of a scheduled trip can be done in a
conventional way at the vending machine or via smartphone. Additional information is displayed on your


Popouts - Causes, Prevention, Repair
Popouts often occur because the concrete has been overworked allowing the aggregates to drift upward toward the surface. The cement paste is significantly weakened as a result and pop outs occur. To help prevent pop outs you should do something to fortify the cement paste. When you apply V-SEAL it causes a chemical reaction in your cement that does just that. The cement paste hardens and densifies thereby increasing the tensile strength of your paste. Once your cement paste is strengthened you are far less likely to see pop outs occur. Some popouts are inevitable, but many that are on the fence can be maintained with a V-SEAL application.


This is what our driveway looks like when it rains:
Generally a bad situation (and something we’ve been worrying about it), but made a lot more pressing earlier this week by the heavy rains and flash flood warnings in our area.
Jamie chose to do something about it: he went out and he dug.
He dug along an indentation where we suspected there was a [likely clogged] drainage pipe. This is what he found:
Seems that when Verizon installed the FIOS line to the house, they ran the machinery right through the drain pipe. The black cable running over the pipe is the FIOS line. The pipe looks mangled in this picture—which it is—but it was also cut right through, and full of mud in both directions. Sigh.
So Jamie dug and dug (while I watched from inside) until he had dug enough of a trench that water from driveway started to drain away from the house.
Not very pretty, right? But here’s how our driveway looked on the day the rain stopped:
No puddles! Success! For now.
One Response to Dealing with the rain
So sorry to see this!!!A royal bummer for sure! Hopefully, a call to Verizon has been made for a review of how they will fix it. The rains were treacherous in old town as well:(

Move over, Superman. Superheroes aren’t the only ones with X-ray vision anymore. The City of Auburn, WA is testing high-performance government technology to help their public works employees "see" and interact with below-ground infrastructure assets.
Projects like these support City of Auburn Assistant Information Technology Director Ashley Riggs' idea that "innovation is a mindset," a continuous process of finding substantive improvements, and not a one-time undertaking.
By pairing Meemim’s augmented reality application called vGIS with Cartegraph’s work and asset management software, Auburn is on its way to better tracking and maintaining the water, sewer, storm, traffic, and communications assets that lay beneath their city. Whether they’re in the field or in the office, staff can see and interact with underground assets without ever lifting a shovel. This futuristic tech is expected to open the door to more dynamic council presentations, easier remote or confined-space inspections, and preventing the expensive repairs and major project delays that come with unintentionally digging up critical assets.
To learn more about the City of Auburn's innovative project, check out their feature article in StateScoop. Want to learn how your local government can become more high-performing like Riggs and his team? Download our free Building High-Performance Government how-to guide now.


What are construction loans and how do they work? A construction loan is designed to allow you to borrow the money for your yet to be built new home. Even though your new home is under construction it can still be used as the security for the mortgage.
The funds for the construction are paid to the builder progressively in a series of drawdowns. These drawdowns are paid as each stage of construction is finished and a successful inspection is completed. This helps minimise the interest you pay as the amount owed grows over the construction period.
Also, construction loans are generally interest only during the construction period, which minimises the borrower’s repayments. This is especially useful to those borrowers who are renting during the construction period.
The lender will require the following additional documentation from the borrower when using a construction loan.
- A copy of council approved building plans.
- A fixed price building contract with a licensed builder. Ensure that this is the final contract, keep in mind that any change to this contracts price can trigger the lender to reassess the construction loan.
- Builders Risk Insurance, a current copy of your builders “Public Liability Insurance”
The drawdowns are paid to the builder in a series of stages. The HIA (Housing Industry of Association) and the MBA (Master Builders Australia) have clearly defined progress payment plans which are commonly followed when drawing down your construction loan. Generally, there are five stages of construction when building a new home:
- Foundation: The Levelling of the site, the laying of the slab and the installation of plumbing. Once successfully inspected 10% of the construction loan funds are drawn down.
- Framing: The building of the frame, the support structure for the entire building. This includes walls, roof trusses, gutters and insulation. After a successful inspection a further 15% of the construction loan is released.
- Lock up: Quite literally your new home is completed to the lockup stage, so external doors and windows are installed. This secures the house for the next stage of construction. Once again, an inspection is required and a further 35% of the construction loan is drawn down.
- Second fix: In this stage all the internal fittings are installed. All the plumbing and electrical works are finished, along with the plasterboard and tiles. The kitchen and bathrooms are mostly finished. After a successful inspection an additional 20% of the construction loan is drawn down.
- Completion: This is the last stage where all the painting and other details are completed. The site is cleaned, and your new home is ready for you to move in. The final inspection is conducted, and a certificate of occupancy is issued. At this stage the final payment of 15% is drawn down from the construction loan and the construction loan converts to a standard mortgage.
One of the services we often recommend to our clients who are using construction loans, is to secure the services of an experienced building inspector to conduct additional inspections at the various stages of construction.
These inspections are to ensure the builder and contractors are completing the construction of your new home to an acceptable standard, with a focus on detecting non-compliance to the various construction codes and substandard workmanship.
It is nice to have an experienced building inspector in your corner ensuring that the construction of your new home is being completed to an appropriate standard.

The demand for drone inspection of wind turbines has increased significantly in recent years. Turbine blades need to be regularly monitored for deterioration and damage, and before drone inspection, the wind energy sector relied on industrial rope crews who put themselves at considerable risk. Even then, a rope crew can’t safely get out to the blades to look at them. With a drone, detailed quality images are much easier and safer to obtain, recording assets, pinpointing damage and collecting data without exposing workers to extreme danger.
A drone in the air above a wind turbine site can gather information and images to be used for monitoring, mapping, planning, and structural analysis. And with a thermal camera attached, visual inspections can be carried out to detect conductor hot spots or broken insulators. As well, drones can map and create 3D images, giving engineers and operators highly detailed views of damage such as cracks or erosion without having to stop turbines from spinning.
The lifespan of a solar panel depends on regular and efficient maintenance. Traditionally, operators relied on long and tedious on-foot surveys, with inspectors walking the aisles of a solar farm carrying handheld infrared cameras; or they would use of manned, aerial flights at low levels surveying the panels with a thermal camera. Not only did these methods take a lot of time and money, but employees were placed in unsafe conditions, as well.
Today, solar farm operators use drone technology to quickly and easily record images and video footage of installations, and analyze data without putting anyone at risk. Drone inspections pinpoint damage and provide updated imagery of damage, cracks, or shading. And, not only can a drone detect damage on a solar panel, it can also monitor the panel’s health. With infrared cameras, defects and temperature imbalances are easily identified, maintaining maximum output.
A drone survey is a fast, economical way to stay on top of maintenance, and keep your solar installation running at optimal efficiency.

A system is described, aiming at reducing the seismic excitation of structures, based on pure struc- tural solutions. The basic idea is to exploit the phase lag of the incident seismic waves along the foundation and, accordingly, to design it in order to possess the adequate stiffness and strength. The longer the foundation is, the larger the phase lag becomes. It is, therefore, well understandable that under this requirement, foundations of the maximum possible length must be designed. The presented methodology might be proved quite valuable for exist- ing structures and especially for monuments, where, in most cases, it is not possible to proceed to the necessary strengthening interventions in the structure above its foundation. As a technical support of the present investigation, the size of the foundation as a two dimensional elastic beam and the velocity of the propagation of the ground motion are examined as basic parameters. Two strong ground motions have been used, each one with quite differ- ent characteristics compared to the other one: an artificial time history of rather high frequency, fitting to EC8, Type 1, ground class A and a natural ground motion of the Edessa, Greece 1990, M = 5.9, earthquake. The Edessa earthquake is characterized by much longer predominant periods of vibration compared to the artificial one. Vari- ous lengths of the foundation beam have been examined in combination with the velocity of the propagation of the ground motion along the longitudinal direction of the beam. The achieved motions at the center of gravity of the beam as well as the pertinent response spectra are calculated. These spectra are compared to the free field ones. At the beginning of the paper, it is tried to explain the inconsistency between macroseismic observations and earth- quake code requirements concerning the effects of the size of the building foundation. At the end of the paper, the results of the described methodology are demonstrated in several practical case studies.
In this paper the effect of underground cavities on the seismic response under incident plane waves of volume and surface has been studied.The numerical solution is obtained using the boundary element method in the BESOIL /14/ computer code that allows a 2D analysis of propagation both of volume and Rayleigh waves, and any geometry of the cavity and the ground surface.The main parameters that govern the phenomenon of amplification are considered and the criteria for determining their importance are provided. Finally a realistic cavity of irregular shape has been examined for different values of its depth and dimension.
After summarising the failure criteria for unreinforced masonry panels provided by the new Italian technical law (NTC 2008), the paper presents a numerical study aimed to investigate the b shape factor. This shape factor is a coefficient used to evaluate the ultimate shear strength of masonry panels for the failure mechanism with diagonal cracking. The numerical results show that the computed values of the coefficient b are higher than those proposed by the rules. Consequently, the shear strength obtained applying the equation given by the NTC 2008 does not appear conservative.
