The overall quality of any project depends on the ability of the structural engineer to balance the characteristics of the various building materials with the individual structure's geometry to ensure that they capture the architects' vision while protecting the lives of the inhabitants.

The BCA structural engineering team conducts ongoing research in pursuit of the most effective and efficient means of design. We approach each project as a team and are able to find solutions to unique design impediments that compliment the design. Our creative solutions and our research applied with our experience and thorough analysis of structures, allows our engineers to expedite design calculations and drawings through public agencies.
