6. Q: Would CDCR be willing to use pressurized cylinders of 2-part urethane adhesive to adhere the fleeceback membrane to the cover board in lieu of water based adhesive? The water-based adhesive is more user friendly, however the 2-part urethane adhesive is more cost effective.

A: No, CDCR will not accept pressurized cylinders in lieu of WB adhesive. We do not find it acceptable, considering our venue, and our workforce's skill level.

7. Q: At the job walk yesterday Durolast came to bid the project. In reviewing factory mutual approvals for Durolast, it has become clear that they are unable to meet the performance requirements of the specifications for this project. Spec section 075419 1.3 calls for an adhered membrane. Spec section 075419 1.4 A 4 calls for Minimum FM1-90 rated assembly. Spec section 075419 1.4 C requires the roofing system to have an FM Roof Nav Assembly ID#. In reviewing the FM database for the Tested Roof Nav Assembly numbers, it has become apparent that Durolast is unable to meet the specifications and performance requirements of the specifications. They have 34 tested assemblies with XPS insulation over a concrete deck. All 34 tested assemblies are for smooth membranes not felt or fabric backed. All 34 tested assemblies are for mechanically fastened membranes. None of the 34 tested assemblies contain a vapor barrier which is required on the lower sections of every roof. Spec Section 075419 1.3 A 3 clearly states that EPS and Polysio cannot be substituted for XPS insulation. Here is the link to review their FM tested assemblies: https://roofnav.app.fmglobal.com/loadShareLinkSearchCriteria/53B6257F- 147F-4717-926C-D39F60BD5935. Is it the State’s intent to follow the specifications and requirements in the specifications? Is the State willing to comprise on the spec requirements to accept a proposal from another manufacturer?

A: The roofing material and assembly for LAC 21-040 Replace Roofs projects must meet the approved Specifications.
