Foremost on the minds of many clients is the preservation of irreplaceable items. Understanding the building envelope and a sensitive approach to respecting building finishes are key elements of a good approach. Our professional engineers have the expertise to design optimally controlled environments using the latest in technology to control conditions like relative humidity and air temperature, so that irreplaceable structures and artifacts can be preserved for future generations. We are adept at integrating and upgrading the mechanical and electrical systems with minimal impact to the building fabric. Our work is routinely subject to reviews by planning commissions and other historic preservation agencies.
