1. BACKGROUND INFORMATION

The National Institute of Standards and Technology (NIST) is a government scientific research facility located in Gaithersburg, MD. The facility buildings largely date to the early 1960’s.

NIST operates a Central Utility Plant (CUP) to deliver several site-wide utility services to the campus buildings. Primary amongst that service is the production of high-pressure steam. This steam production consists of 6 standard boilers and a high efficiency COGEN system. Loss of the capability to provide steam to the NIST Campus jeopardizes the national mission NIST is tasked with.

Generally, most boiler repairs, piping, and associated repairs within the NIST CUP involve American Society of Mechanical Engineers (ASME) certified welding, and a R-Stamp from the American society of Mechanical Engineers (ASME) The “R” stamp is required for boiler shell and internal repair.

This contract operates off a fixed dedicated allocation. The contractor is only paid for authorized services, as needed and approved by the government.

2. PURPOSE

NIST is seeking an ASME “R” stamp qualified boiler repair and welding contractor to perform high pressure steam piping and boiler repair and mobile welding operations on a 24/7/365 callback basis for urgent CUP repairs and limited other repairs in site steam manholes and other spaces on a as needed basis.

3. PLACE OF PERFORMANCE

Work is primarily located at building 302, NIST, Gaithersburg, Maryland.

4. REGULAR BUSINESS HOURS

Regular business hours are Monday through Friday, 6 AM to 6 PM Eastern Time, excluding Federal holidays and NIST closures.

5. PERIOD OF PERFORMANCE

The period of performance for this project is for the base year, and up to four option years.

6. SPECIFIC REQUIREMENTS
