Our seasoned team of registered architects and engineers specialize exclusively in the building envelope.
"...knowledgeable, practical and easy to work with."
"DiMella Shaffer has long history of working with Building Envelope Technologies on renovations and new buildings at Northeastern, Harvard, Tufts and UMass Campuses. BET has supported our architects and designers with detailing tricky conditions, improving our understanding of envelope performance and specifying products. BET shines in their thorough review of shop drawings and excellent field observations. Their staff is knowledgeable, practical and easy to work with. We would recommend them to any owner, developer or architect looking to improve their building exteriors."
"I am very happy to have BET on our team."
"Over the last 10+ years, Lance and his team have proven to be specialists in the proper application of a wide variety of envelope products. They recognize there is never a one-size-fits-all solution, and that each situation may be solved by a variety of different approaches. And because UrbanMeritage specializes in the preservation and development of historically significant buildings in Boston’s Back Bay, I am very happy to have BET on our team."
"Having BET on our project team brings a high level of expertise to the design of our exteriors."
"Having BET on our project team brings a high level of expertise to the design of our exteriors. We have worked with them on several projects and have always found them engaging and willing to improve the performance of our details, while maintaining the design intent. They spend the time understanding what we are trying to accomplish, suggest technologies that we may not have thought of, and follow through with very thorough reviews. Their on-site presence has proven to, not only ensure the design is being followed, but also help solve problems and mitigate any issues that inevitably come up. They are a pleasure to work with!"
"We look forward to working with them again in the future."
BET met with the team weekly to conduct intensive reviews of the progress of work. Their onsite time was invaluable to address and identify existing conditions and to provide quality control review and testing. Their technical expertise in building envelopes and waterproofing was invaluable from design through construction and we look forward to working with them again in the future."
"I cannot imagine pulling off this project without BET."
"BET can provide expertise on the full range of diagnosis, analysis, design, repair, installation and inspection, all backed by unmatched field supervision. They worked closely and extremely well with the contractor and provided testing advice and service. I cannot imagine pulling off this project without BET."
