Commissioning Authority (CxA) Engineering Services

The National Institute of Standards and Technology (NIST) Gaithersburg, Maryland campus is a Research and Development (R&D) facility with 52 buildings located on a 232 hectare site. The NIST site has approximately 3,424,353 GSF of floor space including R&D, office, and service areas. The majority of R&D buildings are technically sophisticated laboratory facilities with specialized environmental and utility systems required for research and experimental activities. NIST Campus facilities are provided chilled water, steam, and compressed air from a centralized utility generation plant located on the campus. Commercial high voltage electricity is received at a main sub-station and distributed radially by multiple facility spot networks. Laboratory facilities typically utilize specialized controls such as uninterrupted power, compressed gas systems, clean-room technologies and tight-tolerance air temperature control systems for the conduct of research and experimental studies. The Central Utility Plant (CUP) has undergone a major re-capitalization program to upgrade and expand installed equipment, facilities, and control systems over the last 3 years. Steam is produced at 150 psi by up to six steam generators located in the CUP (4 nameplate-rated at 44,000 lb/hr and 2 rated at 80,000 lb/hr). There are four (4) Union Iron Works boilers at 55MBtu/hr and two (2) English Boiler & Tube, Inc. at 99.8 MBtu/hr currently installed and operational. All boilers are dual-fired for natural gas and No. 2 fuel oil. NIST has a current requirement to replace boiler burners and install economizers for the original four 44,000 Lb/HR Boilers with an anticipated April 2013 award. New installed boiler equipment and controls must be commissioned and tested to strict industry standards during start-up of each boiler, and comply with the Maryland Department of Environment air discharge permit limitations for each steam generator as it is installed. NIST is seeking qualified professional firms that have the technical capability and experience to perform Commissioning Authority (CxA) Engineering Services for the government for an upcoming construction contract to replace burners on boilers 1 to 4 of the NIST Central Utility Plant (CUP), including new economizers with forced draft fans and integration of burner and combustion controls with existing plant controls systems. The principle field of professional expertise will be mechanical with a technical emphasis on industrial boiler/steam generator systems and controls. The selected firm will provide a competent individual/team with specialized qualifications that include experience and past performance in the commissioning and start-up of Industrial/Central Utility Plant (CUP) equipment and systems (industrial boilers, industrial fan-driven economizers, pumps), direct digital and pneumatic control systems, and supporting ancillary systems (natural gas fuel trains, oil fuel distribution, variable frequency drives) similar to the scope and complexity of this construction project. A detailed Statement of Work for the CxA Engineering Services is attached for the requirement. Categories of required services are: -Perform construction document (peer) review -Develop project specific commissioning plan -Develop testing checklists and schedule -Conduct performance verification (witness) testing -Lead commissioning team meetings -Develop, maintain, and track to completion the Issues Log -Compile and maintain all commissioning and testing data and documentation close-out The contract will be Firm Fixed Price. Solicitation to be issued on or about April 24, 2013.
