W|A Associates  specializes in the technical detailing of building envelopes, roofs, decks, fire resistive systems, buried and exposed membranes and traffic decks, waterproofing and flashing, coatings, sealants, fenestration and penetrations.


Architectural firms whose primary focus is on design find our technical services particularly relevant to enhance the durability of the resulting structures. W/A provides services for the full production of construction documents and specifications for those firms who prefer to remain focused on their design work.

Investigation & Analysis of Building Failures


Our firm is well-known for our expertise in the investigation of construction deficiencies and the cause of building failure. Our further expertise in historic restoration, litigation and forensics services allows us to effectively contribute to the discovery and recording process that is required in litigation/mediation cases.


W|A Associates  provides services ranging from informal assessments to thorough destructive investigations and preparation of comprehensive reports. Evaluation of the structural integrity and safety of a building can also be provided, including conformance with the original construction plans and specifications, applicable building codes and industry standards. 


These investigations involve location and identification of construction deficiencies, analysis of the impact of defects on the performance or safety of the structure, recommendation of solutions, preparation of estimates of the cost of repair and identification of responsible parties. Solutions for the resolution of construction deficiencies are the primary focus of the reports developed from the observations of these investigations.
