The Pennsylvania State Police (PSP) Departmental Headquarters in Harrisburg, PA, underwent a building envelope rehabilitation to enhance its performance and modernize its appearance. The project focused on the transformation of the entrance façade, progressing through several key construction phases. Initially, the building’s pre-construction condition was documented, highlighting the need for improvements. The renovation began with the installation of new curtain wall framing and insulated sheathing, followed by the application of an air and water barrier to ensure weather resistance. As the project advanced, curtain wall glazing was installed, significantly improving the building’s energy efficiency and aesthetics. The final design, as depicted in the rendering, showcases a sleek and contemporary façade that aligns with modern architectural standards. Completed in December 2020 at a construction cost of $10.1 million, the project included comprehensive architectural services, from programming and design development to construction documents, technical specifications, estimating, and full construction administration.
