This document describes a federal solicitation for construction services. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 15 is seeking a contractor to replace existing exterior windows with a new, energy efficient window system in Building 1 at Z2DA--657-19-110JC. The scope of work involves demolition, hazardous material abatement, and safety and infection control measures. The contractor must provide a project schedule and complete a pre-construction risk assessment. The period of performance is 730 calendar days from receipt of the notice to proceed. The building will remain occupied during construction, so the contractor must coordinate activities to avoid negatively impacting ongoing operations.
