Core & shell buildings with separate tenant improvements can be complex
This 300,000SF five story build to suit commercial office project was developed by Panattoni Development Company for the General Services Administration to house the Federal Aviation Administration. Landed via a competitive Request for Lease Proposal process, the design and construction was required to meet Federal High Performance Sustainable Building standards and deliver a LEED Gold certified tenant improvement. Due to the complexity of the sustainable requirements, ArchEcology was brought onboard to help with the RLP response that secured the project.
Both the base building and tenant improvements were designed concurrently by the same team and constructed by the same contractor under separate contracts. The design faced a complicated overlap of federal lease, HPSB and LEED requirements for both the base building and the tenant improvement that necessitated ArchEcology to monitor and evaluate design options carefully. The core and shell project, which also elected to pursue LEED Gold certification, was a warm, lit shell so the majority of the HVAC and lighting systems were installed as part of the base building. The tenant improvement built out the office space, along with a café and fitness center.
Many members of the project teams were used on both core & shell and tenant improvement projects which made communication easier but tracking and distinction of documentation a little bit harder. In addition to managing the documentation and online submittals for both LEED projects, ArchEcology was responsible for energy code modeling for permitting, energy modeling for LEED compliance and energy modeling for PSE rebates that successfully obtained a $200,000 grant. Ultimately both projects received LEED Gold Certification in 2019.
Project was designed by CollinsWoerman and was constructed by Abbott Construction.
