The purpose of the Pierre Federal Building project is to modernize the building by replacing the existing curtain wall system, mitigate water infiltration issues and repair stone soffit panel connections while updating the architectural appeal of the building. The existing windows, granite spandrel panels and associated interior finishes will be removed. A new curtain wall with high performance glazing and insulated spandrel panels will be installed and any affected interior finishes, mechanical and electrical systems will be re-installed or replaced. A new entrance canopy, integral to the design, will also be constructed as part of this project. The architecture of the new facade will reflect the prominence and dignity of the many federal agencies it houses such as courts, the U.S. Attorney's Office, the U.S. Marshals Service, U.S. Probation and the U.S. Postal Service. The new curtain wall system will improve energy efficiency by a minimum of 20-30%, exceeding ASHRAE 90.1-2007, and increase daylighting, thus lowering energy consumption and operating costs while improving occupant comfort. The water infiltration and repaired soffits will increase safety and reduce maintenance. Energy modeling will be used to objectively measure the energy use and determine if the building meets the federal energy goals. As a design-build project, synergies will be achieved through the collaboration of the project team from inception to final completion. The team will strive to provide a high quality outcome at the best value to the Federal Government. The overall results of the contract will be to bring the building into the 21st century and position it to be functional and efficient for decades to come.
