About this file
This is a Questions and Answers document issued by the Housing Authority of Salt Lake City (HASLC) regarding Invitation for Bid (IFB) #26-017 for roof replacement services at Phillips Plaza, a public housing property located at 660 South 300 East in Salt Lake City, Utah. The project encompasses approximately 8,827 square feet of roofing, including the main roof and two penthouse roofs, with the existing system comprising a built-up tar-and-gravel roof with approximately one layer, tapered insulation, 35 penetrations, flashings, and eight roof drains over a wood structural deck. HASLC conducted non-mandatory site visits on August 13, 2026, and September 1, 2026, to allow bidders to assess existing conditions. The bid deadline has been extended to Friday, September 11, 2026, at 5:00 p.m. MDT. Bidders must submit a Base Bid for complete tear-off and replacement with a manufacturer-approved TPO attachment system meeting code-compliant insulation and energy compliance standards, along with a separately priced Owner Option credit for roof recovery if post-award investigation confirms feasibility.
The Base Bid must include new insulation, drainage improvements, flashings, roof drains, and a 60-mil white TPO roofing system with a minimum 60-year warranty. Bidders must also provide additive alternate pricing to upgrade to 80-mil TPO and unit pricing for additional or concealed-condition work. Although the IFB does not require a fully adhered TPO system, bidders may submit clearly identified alternate scopes and pricing, including fully adhered systems, provided such alternates are submitted in addition to and not in place of the required pricing. No pre-award roof-core report or moisture survey is available; however, the post-award roof investigation and moisture survey, including core cuts as appropriate, are included in the Base Bid. HASLC will coordinate with equipment owners for removal of rooftop communications equipment, coordinate any necessary chiller-piping adjustments, and coordinate resident access for roof-drain work if apartment access or ceiling modifications are required. Bidders are responsible for investigating and accounting for all roof-drain work and may propose contractor-developed surface-drainage alternatives using scuppers or downspouts, subject to HASLC approval and applicable code and warranty requirements.

Phillips Plaza Roof Replacement Questions and Answers
IFB #26-017
Site Visit and Existing Conditions
1. Were site visits offered?
Yes. The IFB scheduled and published a non-mandatory site visit for Thursday, August 13, 2026, at 10:00 a.m. MDT.
HASLC also offered an additional non-mandatory site visit on Tuesday, September 1, 2026, at 2:00 p.m. MDT at Phillips Plaza, 660 South 300 East, Salt Lake City, Utah 84111. Both site-visit dates have passed.
2. What is known about the existing roof?
The IFB identifies a built-up roofing (BUR) tar-and-gravel system with approximately one roof layer, tapered insulation, approximately 35 penetrations, flashings, and approximately eight roof drains. The structural deck is believed to be wood but must be verified by the Contractor.
3. Is a pre-award roof-core report available?
No. HASLC does not have a pre-award roof-core report identified in the IFB. The post-award roof investigation may include core cuts, as appropriate.
4. Is a pre-award moisture survey available?
No. After award, the Contractor must perform the Attachment A roof investigation and moisture survey to verify the assembly and evaluate whether it is suitable for recovery. The investigation is included in the Base Bid.
Roofing System and Bid Alternatives
5. Does the 1.5-inch ISO/RhinoBond assembly apply to the Base Bid?
No. The 1.5-inch ISO/RhinoBond assembly applies to the Owner Option - Roof Recovery System.
6. How should bidders price the required scope?
Bid the IFB scope as written: submit the Base Bid for full tear-off and replacement and separately provide the Owner Option - Roof Recovery System Credit. The Base Bid requires code-compliant insulation and a manufacturer-approved TPO attachment system for proper energy compliance and drainage.
7. Is a fully adhered TPO system required for the Base Bid?
No. The IFB requires a manufacturer-approved TPO attachment system; it does not specifically require a fully adhered system.
8. May bidders submit alternate scopes and pricing?
Yes. Bidders may submit clearly identified alternate scopes and pricing, including a fully adhered or other recommended system, for HASLC's consideration. Any alternate must be submitted in addition to, and not in place of, the required IFB pricing. The required Base Bid remains the basis for determining the low bidder. Line items specifying additional requirements believed to be applicable should be specified separately with pricing to ensure proper bid leveling.
9. When are bids due?
The bid deadline has been extended. Bids are now due Friday, September 11, 2026, at 5:00 p.m. MDT.
10. How will the rooftop communications equipment and support framing be handled?
HASLC will coordinate with the equipment owners and the selected roofing contractor to accommodate the work. An equipment owner will be responsible for removing its equipment and related steel support framing.
11. Who is responsible for modifying the chiller piping?
HASLC will coordinate any necessary chiller-piping adjustment during the roof replacement. This work is outside the roofing contractor's scope.
12. Will HASLC coordinate resident access for roof-drain work?
Yes. Bidders should investigate and account for the roof-drain work before submitting bids.
If replacement requires apartment access or ceiling modifications, HASLC will coordinate with affected residents. HASLC will also consider a contractor-proposed surface-drainage alternative using scuppers or downspouts, subject to HASLC approval and applicable code and warranty requirements.
