Note: Input power for temporary leased boiler cannot be over 100MMBTU/Hr.

1.1.2. The “work” shall mean to provide and install a fully operating and functioning system, assembly, framework, fixture or apparatus that is complete, finished and ready for use by the Government.

1.1.3. The Contractor shall be responsible for identifying the necessary logistical, architectural, structural, mechanical, fire protection, and electrical work elements required to install the new systems and assemblies as described herein. Assemblies, framework, fixtures or apparatus not readily identified on plans or the Statement of Work (SOW) shall be provided by the Contractor as required for a complete, fully operating and functioning system or systems, ready for use by the Government.

1.1.4. Plan information such as floor plan layouts; basic dimensions; design requirements for structural, mechanical and electrical data; and location of utilities provided by the Government for this installation are based on available as-built documentation, field observation, and equipment selected as design basis by the Government. This information is to be considered approximate and shall be field verified by the Contractor.

1.1.5. The Contractor shall also perform a site investigation to verify existing conditions and if necessary, pull additional as-builts if available from Building 400, Engineering Support.
