Pre-Construction Services

As every project has its unique challenges and personality, we approach each with an open mind and clean slate. Our goal: provide precisely the services needed through teamwork and flexibility. From the very beginning, we actively look for ways to help the owner and architect/engineer make design decisions by supplying budgets, value engineering, and suggestions for alternative materials. We search for solutions to problems, do on-site investigations and look for what is missing.

“JMA is the absolute top of the line. I was the client rep on a construction and preservation project that they did – their attention to detail is stunning. The project included the retrofit of an adobe home that was built in 1842 and required intense precision. The outcome has been nothing short of mastery! This adobe will live in perpetuity and it retains its historical integrity and cultural importance to Sonoma. They also came in on time, which was against all odds with this property, and its scrutiny by the city and county. Job well done!”
