We are often hired by architects to provide professional expert advice related to building envelope assemblies. At the start of the project, we provide waterproofing system recommendations and associated material recommendations suitable for the project. During the Design Development and Construction Document phases, we review the drawings and details to ensure that the building enclosure elements are properly integrated and communicated. We also review the written specifications to verify that they are coordinated with the drawings and communicate the desired requirements for the project. As architects and engineers ourselves, we are familiar with all aspects of the design process, yet with our technical experience we also understand the limitations of constructability. Seeing the problem from both viewpoints, we can recommend solutions that are functional, practical and cost-effective.
