Building an Envelope Warranty
When plans for buildings are being laid out and constructed many parties are often involved including the owner, architect, general contractor, and sub-contractors. One of the key areas of planning is waterproofing the structure so that leaks do not occur. In many cases a rainscreen system is built and put in place.

Built to burn: Thousands of buildings worldwide are wrapped in combustible panels
A high school in Alaska, a National Football League stadium, a Baltimore high-rise hotel and a Dallas airport terminal are among thousands of structures world-wide covered in combustible-core panels similar to those that burned in June's deadly London fire.

After Years of Decline, Asbestos Use is on the Rise
Do not believe that asbestos is not being used in building products that you specify or construct. Contrary to popular belief asbestos is not illegal in the U.S. According to the EPA many building products can be manufactured with asbestos.

Every layer matters. A holistic approach to quality control can be useful.
Whose fault was it? This is a frequently asked question when an exterior wall leaks, rots, or falls down. During a construction failure investigation, contractors often highlight the defects of other trades that affected their work. Defects include those that were documented during construction but not corrected. This may be due to timing and scheduling constraints.
Often the findings from building failures are then used going forward as best practices for new construction. However, those learned best practices should not be the only guideline. Critical areas that need to be addressed include the points of intersection, as many times there are multiple layers of building materials which are put in place by various subcontractors. This step is known as a pre-covering inspection. A pre-covering inspection of each layer at each wall area would be ideal, so problems at each layer do not accumulate, influence other layers, or get concealed.
The following article looks at examples of pre-covering inspection criteria to illustrate the influence each layer may have. Continue reading….

Hurricanes and Construction Cranes - Look Out Below
During Hurricane Wilma a tower crane at a high-rise condominium construction site in Hallendale, Florida suffered a collapse. The building, a 28 story concrete structure, is situated between the Atlantic Ocean and Route A1A, and was under construction at the time of the collapse. The crane was situated on the west side of the building and was connected to the building at the tenth and twentieth floors. The crane was over 300 feet tall. The crane broke at the twentieth floor; the top of the crane fell to the ground while the lower portion was damaged but remained attached to the building. CCA was requested to review the circumstances of the collapse of the crane and provide opinions as to the cause.
Stricter Building Codes Saved Florida’s Commercial Buildings from Irma’s Wrath
Hurricane Irma bore down hard on single-family homes, severely damaging many. At the end of September residential insurance claims had been cited around a half-million. The story, however is quite different for commercial and industrial buildings where insurance claims had been cited around 25,000.
This is mainly due to the stricter building codes that were put in place following the wrath of Hurricane Andrew in 1992. “Designed to withstand a Category 5 hurricane with winds of 175 mph, the Florida building code is the accepted benchmark for hurricane protection nationally.”
“Florida significantly strengthened its defenses after hits from past major hurricanes, and those improvements were instrumental in helping the state weather this potentially devastating storm,” Levy notes. “As a result, damage to Florida commercial real estate is relatively minor outside of the Keys.”

Hurricane Ties - Keeping the Lid On
With the 2017 hurricane season coming to an end Harvey, Irma, Jose, and Maria affected large parts of the USA and Caribbean. Examples of roof uplift can be found in numerous structures. If a roof is not properly tied down the entire roof structure can be blown away as in this photograph from St. Thomas.
When hurricanes or high winds strike buildings the roofs can be sucked upward in the same manner as an airplane wing. In extreme cases the entire roof structure can get sucked off the building. Newer, hurricane-resistant structures incorporate hurricane ties - metal straps which attach the roof securely to the main part of the house below. Parts of the house are also tied together all of the way down to the foundation providing a path for the roof uplift forces all the way to the foundation. Without these ties, strong winds will make quick work of a roof.
Increasing Demand for Hotels keeps Construction Boom Going
The hotel business continues to reach new heights with greater and greater demand for more occupancy. As such, developers continue to build and open new hotels across the country.
In fact, according to a recent article in National Real Estate Investor, the number of new hotel rooms planned for this year is up 9% as of the end of September.
Room demand is at an all time high. "The U.S. hotel industry - through August - has sold more rooms than ever before." This is mostly due to the U.S. economy being relatively strong: "Healthy corporate profits continue to create demand for business travel. And because unemployment is relatively low and the purchasing power of many families is strong, consumers continue to travel for leisure. The damage created by Hurricanes Harvey and Irma also inflated the demand for hotel rooms in Texas and Florida, as people whose homes were damaged needed to find other places to stay."
