Facade cladding failures are a leading cause of building construction problems and claims after construction is completed. Bringing an expert into your Design Team early in the design process helps avoid cladding design deficiencies. HDG's consultants quickly pinpoint problem areas and resolve technical issues before they become building failures.

  HDG validates the contractor's system design through a laboratory mock-up and provides valuable in-depth assistance to our clients during this phase of the work. HDG ensures that AAMA and ASTM guidelines are followed by reviewing mockup drawings, structural calculations, samples, and other product information. HDG also witnesses erection, pre-testing, and final testing of mock-up specimens at test facilities, reviewing comments the laboratory reports after the tests
