Is the lower roof area near the northeast corner, the one that has been reroofed with TPO single-ply, included in the work for this bid? This section of roof is excluded from the Base & Alternate Bids. If so, is it to be included with the Alternate Bid No. 1, or the Base Bid? See answer above. 5. Is a vapor barrier required to be part of the new roof assembly? Section 07220 [Roof and Deck Insulation], Part 1, 1.01, A. makes reference to a vapor barrier. No Vapor barrier required, however the roof is required to meet a Class A Fire Rating 6. What is the minimum R Value that we are to achieve with the new roof insulation? N/A Section 07220 [Roof and Deck Insulation], 2.02, A., 2., states that the thickness is to be " 4" or as required to meet thermal requirements specified above." Is the thermal requirement, or R Value, specified anywhere? I have not been able to find its location. No roofing insulation is required. Addendum 2 – 8135 Roof Replacement at 281 N Collge Page 4 of 4 7. If the minimum R Value of the new roof insulation is such that its thickness will require the raising of HVAC units & curbs, duct penetrations and condenser units, as well as the service hook-ups [electrical, gas & refrigerant lines], will this HVAC/plumbing/electrical work be done by City of Fort Collins directly, i.e.: would the City contract directly and independently with a mechanical contractor? N/A Or, will this work be made part of the roof replacement contract with the roofers thereby becoming general, or prime, contractors to a mechanical subcontractor? No since no roofing insulation is required. 8. If the minimum R Value of the new roof insulation is such that its thickness will necessitate modifying [raising] the windows at the well roofs, who will be responsible for this window modification work? N/A Will the City of Ft. Collins hire a separate contractor to perform this work or will it be the responsibility of the roofer to become a general, or prime, contractor and hire the appropriate subcontractor to perform this work? N/A Will there interior finish work involved? N/A If the roofer is to be the prime contractor for this work, will the City issue specifications that will describe the materials, methods, and scope of this work? No since no roofing insulation is required. 9. Regarding the skylight curbs. They also may be too low [depending on the thickness of the new roof insulation] and will have to be raised. Is this work to be incorporated in the roofer's contractor [i.e.: to perform with in-house forces or to subcontract out] or will it be done by the City contracting directly with a separate contractor? N/A If raising the skylight curbs will be the responsibility of the roofers, will there be new interior finish work [i.e.: drywall, painting] required? N/A Will the City provide specifications that will describe the materials, methods and scope of this work? N/A. skylights are not in the scope of work and will not need to be raise etc. since there is no roofing insulation required. 10. Would the City consider extending the bid due date? See Addendum 1 – the bid date changed to July 24th (from July 10th).
