jet propulsion lab

NASA Jet Propulsion Lab B230

NASA Jet Propulsion Lab B230, Pasadena CA

Project Description:

TMCx Solutions, LLC was contracted by Jet Propulsion Laboratory (JPL) to provide Construction Phase commissioning for the JPL B230 Phase 2 project. This project is a 6,000 square foot 1-story space located at Jet Propulsion Laboratory (JPL)]

Scope of Work:

TMCx provided Fundamental Commissioning services for the construction phase. We conducted functional testing and pre-functional test verifications of Chilled Water System, Air Handling System, Ventilation, Terminal Units, Plumbing, Electrical Power, Fire Protection. In addition, we witnessed major equipment start-ups; assisted with test and balance report verification; and organized and developed project documentation as required to document the Commissioning process.

Systems:

Chilled Water System – Rear Door HX – Hydronic

Air Handling System – Make-Up Air Unit, Air Handling Unit

Ventilation – Exhaust Fan

Terminal Units – Fan Coil Unit – Hydronic, CRAH – Hydronic, Air Conditioning Unit – Packaged DX, Humidifier

Plumbing – Condensate Pump

Electrical Power – Standby Power System (UPS), Power Distribution Units (PDU), Cabinet Distribution Units (CDU), Remote Power Panels (RPP)

Project Snapshot

  •  Owner: Clark County RPM
  •  Project Size:  717,000 sq. ft.
  •  Construction Cost:  $25M
  •  GC: US Mechanical
  • Year of Completion:  2020

Challenges and Successes

  • During functional testing it was observed that the chilled water system was not being maintained in order to satisfy all equipment in area due to an optimization sequence implemented at the central plant. The Chilled water pressure would reset based on demand. This reset prevented the system from operating as designed. During integrated systems testing it was determined that the chilled water system would not reset below 35 psi in order to maintain the RDHX system at designed pressure. Correct operating differential pressure allows for system to operate at optimal conditions while maintaining all humidity and temperature requirements in the critical spaces.
  • During functional testing it was observed that not all points were documented in the points list for fire alarm system Corrected list was provided and reviewed. Correct and accurate as built documentation allows the end user to facilitate and expedite corrections and improvements in the future.
