AWS’ services include working with the design team to find the best system solutions for the building envelope. Interacting early during project development allows our team to provide system options and pricing alternatives that meet the performance and price objectives of the project.
Understanding the design intent and the budget parameters allows our team of engineers to work through the interface of the various products that have a dramatic impact on issues such as thermal capacity, moisture management and life cycle performance.
With four architects on staff, we provide BIM based solutions, systems detailing and interface engineering. Having these resources in-house allows us to provide solutions quickly so your team can move forward with a full understanding of available options.
As the project progresses through the design phase, AWS is able to develop estimates for both materials, manufacturing and installation. Our estimating department sources products from around the globe that meet performance objectives, LEED requirements, and cost parameters.
AWS’ awareness and accuracy in the cost analysis process comes from years of manufacturing custom systems as well as installing them. We have a clear understanding of the costs and lead times associated with with material transport, material production, project layout and erection, as well as all aspects of project management.
In order for your project to be a success, the primary objectives must be defined and broken down into detailed components. Each component must be analyzed for cost and schedule. AWS contributes to your efforts in the design phase by clearly outlining the options available for each objective.
New technology being used in engineering and manufacturing are allowing custom systems to become standard. AWS has tested several systems at independent laboratories. This process provides vital information about the tolerances of the system as well as the interface of various products. It is where we erect, dissect, and test the system in order to build it correctly. Similar to automobile testing, we don’t leave the lab until the system meets or exceeds the safety and performance requirements. Some of the tests AWS has done are listed below.
U.B. Code Seismic Racking Test: Verification that the system is designed to withstand seismic activity. System is racked vertically several times, mimicking seismic force to test structural integrity and sealants.
ASTM E 283 Air Infiltration Test: Air infiltration testing seals the building mockup to an air chamber which deflects the building skin allowing for inward/outward pressure to be exerted on the skin. System is then checked for air leakage.
ASTM E 330 Structural Design Load Test: Applying 6.24 pounds of pressure per square foot in this tests recreates 50 mph winds on the building skin. With the use of caliper dial indicator, the deflection of the system is then physically measured to ensure deflection remains within specified tolerances.
ASTM E 331 Static Water Penetration Test: Static water is applied with a spray rack at 10 lbs. per square foot (equal to 5 gallons/hour/square foot) to the building skin continuously for 15 minutes while chamber is sealed and exerting negative pressure. This tests to see if the water can be ‘pulled’ into the system.
ASTM E 501.1 Dynamic Water Penetration: This test utilizes an airplane propeller behind the water spray rack to mimic hurricane force winds. Test duration is the same as static water test.
ASTM E 783 Field check for air infiltration
ASTM E 1105 Field check for water penetration/static pressure
ASTM E 501.2 Field check metal curtain walls
ASTM E 502 Field test - windows
ASTM E 503 Field test - curtain walls
