Did you remember to...? List of things it's best not to forget on a project

Did you remember to...? List of things it's best not to forget on a project
I really appreciate this set of "Lessons Learned" on the Life Support Facility (Building M6-490) at NASA's Kennedy Space Center in Florida. Frank, revealing, sometimes obvious, but interesting nonetheless.

  • Firestopping and backerboard fire retardant paint did not meet LEED requirements.
  • Missing floor concrete sealer specification—should ensure that all specs are kept for LEED compliance.
  • Should allow for maintenance training on plumbing fixtures (i.e. waterless urinals, dual flush toilets, etc.).
  • Proper use of AHU and occupancy sensors is critical—found some sensors to be missing.
  • Easy to overlook required trending and specifications for the HVAC Controls.
  • Must have all proper controls interface cards for HVAC equipment.
  • Proper control sequencing for HVAC equipment was not always available during Occupied mode.
  • Contractor should pay for additional Commissioning Authority (CxA) time if controls & equipment are not ready when scheduled.
  • CxA should provide a formal briefing prior to equipment start-up to ensure everything is ready to operate.
  • Commissioning should be scheduled through NASA only after all controls and equipment have been installed.
  • A Measurement & Verification (M&V) Plan must be drafted prior to bid, so bidders can price the correct M&V option.
  • Make sure to acquire subpower meters for Measurement & Verification (M&V) of lights, HVAC and process loads.
  • Use of a control system designed with iLons may not be LEED friendly; limited fixed memory offered by iLons make necessary trending difficult and a more flexible design may be required.
  • Teamwork is crucial to project success.
