This design-build contract for the National Institute of Standards & Technology (NIST) includes providing all labor, materials, tools, equipment, testing, project management, coordination, and performing all work to install new gas laboratory lines and a gas monitoring system in Building 227 (Room B363 & service gallery) for a Gas Isotope Ratio MS equipment.
The project scope of work includes providing and installing vented gas cabinets for sulfur dioxide (SO2) and carbon monoxide (CO) in service gallery, sprinklers to the new gas cabinets for sulfur dioxide (SO2) and carbon monoxide (CO). Matos is providing and installing a purge system using nitrogen gas for the sulfur dioxide (SO2), carbon monoxide (CO), and hydrogen (H2) gas systems. Nitrogen cylinders for the purge system are provided by NIST. Matos is providing and installing ultra-high purity (UHP) tubing, valves, regulator, and fittings for sulfur dioxide (SO2), carbon monoxide (CO), hydrogen (H2), nitrogen (N2), oxygen (O2), argon (Ar), Helium (He), and carbon dioxide (CO2) gas systems in accordance with NFPA 55. CGA valves, cylinders, and racks for nitrogen (N2), oxygen (O2), argon (Ar), Helium (He), and carbon dioxide (CO2) are provided by NIST. Cylinders for the sulfur dioxide (SO2), carbon monoxide (CO), and hydrogen (H2) are provided by NIST. All regulators have an outlet pressure of 5 bar.
Matos is providing and installing a semi-automatic switchover panel for Helium, ventilation for the new gas cabinets, and connecting the terminal unit to the existing BAS. Matos is removing the existing manifold inside the existing H2 gas cabinet and reinstalling it outside of the cabinet to make room for the new H2 cylinder. The project scope of work includes providing and installing a new toxic gas monitoring system in accordance with NFPA 72 for class A system section 17.10 and NIST’s suborder 7101.61 Compressed Gas Safety and will be tying into the existing Simplex fire alarm system. Matos is verifying the gas limits for any required alarm levels (ex. low, high) with any applicable codes or standards. Matos is also providing all necessary alarm levels (example Low, High). The order of operations includes the following: (1) The local gas detector is monitored by the Gas Detection system controller, (2) The Gas Detection system controller is then monitored by the Fire Alarm system, (3) The fire alarm system is monitored by the Fire Department.
The scope of work also includes installing a compressed air gas system including rack for compressed air cylinder, tubing, regulator, CGA valve, and snorkel tubing and attach to existing ductwork in ceiling.
