The project included providing MEP design services to support the Capital Life Church HVAC replacement project. Engenium Group provided an initial survey and report including a summary of existing systems and condition, and a Schematic Design narrative outlining HVAC replacement options for the Church.

The Church decided to move forward with an option that included a new 12,000 CFM, 50-ton VAV AHU in the fenced area on grade level outside the mechanical room to serve both the sanctuary and basement level. The Church also opted for MERV 8 pre-filters and MERV 13 final filters for the HVAC system.

Capitol Hill Baptist Church

Engenium Group provided MEP consulting services to support the feasibility study for the renovation of Capitol Hill Baptist Church located in Washington, DC. The MEP systems serving the administration portion of the building were outdated with complaints including poor circulation, acoustical issues, and other general deterioration concerns of an aging infrastructure. Having pursued piecemeal renovations over the last 20 years, the Church engaged Engenium Group to identify a comprehensive plan for addressing the remaining maintenance issues and potential basement renovation.

Engenium Group completed an assessment of existing MEP systems and identified solutions to reuse, repair, or replace existing MEP systems serving the education wing and basement. The final report also included recommendations for MEP modifications to support the architectural reconfigurations at the basement level and back entrance.
