  1. Scoping a Commissioning Job in Terms of Contractor Involvement ???

  2. Systems to be Commissioned Or Contractor Performance Expectations What do we mean by Scope?

  3. Owner ? Doesn’t know what to expect Contractor ? Do less work . . . Make more money Design Professional ? We don’t do means and methods Whose Expectations?

  4. Owner, Architect, CM, GC? CxA ? We don’t define Scope, but we should help. Just like Owners Project Requirements Just like Basis of Design Should it be in the Cx Spec? Whose Should Define Expectations?

  5. So far, the design Community has not paid much attention to Cx. Specs. MasterSpec Section 230800 Cx of HVAC (01815) (15995) CxA’s Responsibilities Provide Project specific construction checklists and process test procedures. Direct Cx tests. Verify testing, adjusting and balancing of Work are complete. Provide test data, inspection reports, and certificates in Systems Manual. What About Specs.?

  6. MasterSpec Section 230800 Cx of HVAC (01815) (15995) Contractors Responsibilities Perform commissioning tests at the direction of the CxA Attend construction phase controls coordination meeting. Attend TAB review and coordination meeting Participate in HVAC orientation and inspection as directed by CxA Provide information requested by CxA for final Cx documentation. Provide measuring instruments & logging devices and provide data acquisition equipment to record data for the complete range of testing for the required test period. Not Process or Scope MasterSpec is “product oriented” What About Specs.?

  7. ACG specifications Section 01815 (15995) (230800) CxA Responsibilities 4 pages of criteria Organize and Lead Develop schedules, schedule meetings Develop documentation: RTFs, SVCs, FPTs, Cx Plan Monitor Point to Point, witness startup Understand, direct and witness ALL FPTs Schedule and verify training Complete report What About Specs.?

  8. ACG specifications Section 01815 (15995) (230800) Contractors Responsibilities Evaluate deficiencies Cooperate with CxA Attend meetings Review Cx documentation Complete Checklists Accomplish test procedures Provide Training This is More Process than Scope What About Specs.?

  9. What’s the problem? Interface between trades Actually completing the project Making sure the systems function before functional testing What if the balancer was not truthful Who is responsible for making sure the building is tight. So back to Scope

  10. How do we fix it? Do we help define contract boundary limits? Do we ask the contractors to write narratives? So back to Scope

  11. How do we get to the end? What happens if the CxA and the owner do everything right but the contractor won’t finish If there is only 10% retainage left on the project and the contractor walks away. So back to Scope

  12. Thank you Does anyone have Comments?
