L.S. Grim Consulting Engineers was the mechanical, electrical, and plumbing engineering consultant for this project. The project consisted of the comprehensive renovation and upgrade to an existing stone museum facility and offices. It is constructed of natural limestone with wooden shakes that mimics a colonial era German-style house. It serves as a support building for the Hager House itself, located in the City Park in Hagerstown, Maryland. The lower level of the Hager House Museum consists of display cases for artifacts from the site, such as pottery, wooden tools, and various frontier items. We were responsible for providing a comprehensive HVAC system for this part of the building that not only controlled temperature, but also controls humidity to allow for a stable environment of the display of the artifacts. Part of the project involved reworking the existing, non-handicap accessible toilet rooms in such a manner as to allow for handicap accessible toilet rooms for museum guests. The upper level of the building consists of administrative offices for the curator and other personnel who work at the Hager House and the museum. This portion of the project involved the installation of a new central heating and cooling. In addition, L.S. Grim Consulting Engineers was responsible for the comprehensive upgrade of the electrical service entrance to the facility, taking it from an overhead power distribution system to an underground system. From the new central underground system, we would back-feed the Hager House, provide new service panels for the Hager House Museum, and back-feed various site lighting and festival convenience outlets located within the City Park.
