Competitive Bid Coordination

We help Tucson and Pima County asset owners write roofing scopes detailed enough to run honest multi-contractor bid processes — then we submit our own bid on equal footing with every other contractor.

Most commercial roofing bids in the Tucson market fail as competitive processes before the first contractor shows up. The scope is too thin. One contractor specifies 60-mil TPO; another quotes PVC without documenting the reflectivity value. One prices fully adhered attachment calibrated to Sonoran Desert thermal cycling; another quotes mechanically attached without specifying the fastener density at perimeter and corner zones. One includes a 20-year NDL warranty path with manufacturer-documented maintenance; another does not price warranty coordination at all. The building owner gets three numbers with no way to compare them.

This problem compounds on public-sector projects in Tucson. State agencies purchasing roofing services under Arizona Procurement Code ARS 41-2501 require documented competitive sourcing, and Pima County, TUSD, and Vail School District all have procurement policies that require scope equivalency — the auditor checking the bid file needs to see that all vendors priced the same project. An underdeveloped scope that allows contractors to price different membrane thicknesses, warranty paths, or attachment methods does not satisfy that requirement. It just generates three numbers that cannot be verified as equivalent.

We help owners write the scope document that levels the playing field before the bid goes out. We then participate as one of the bidders. If you select another contractor, we have done the work anyway — a credible process protects our standing in the Tucson owner community, and that is worth more to us long-term than any single project.

What the Scope Document Covers for Tucson Buildings

A bid-ready roofing scope for a Tucson commercial building specifies: membrane product line and thickness (minimum 60-mil TPO or PVC, specified with the ENERGY STAR-required solar reflectance value under Arizona IECC 2018 for Climate Zone 2B), attachment method (mechanically attached or fully adhered, with fastener pattern density designed against the building's ASCE 7-22 wind-uplift zone and Pima County exposure category), insulation specification (polyiso R-value to current IECC minimums, cover board type and thickness, tapered package if required for drainage), flashing details at all penetrations, drains, parapets, and curbs (by reference to the specified manufacturer's published detail library), warranty path (15-year vs. 20-year vs. 25-year NDL, with or without manufacturer-funded labor and maintenance documentation requirements), and closeout documentation requirements (photo log, roof zone diagram, warranty registration, maintenance contract).

Scopes that leave membrane thickness and reflectivity unspecified create the bid spread that makes competitive processes meaningless in this market. A single membrane grade change shifts installed cost enough to produce a $30,000 to $60,000 gap on a 75,000 sq ft Tucson commercial roof — a difference that has nothing to do with contractor quality or efficiency. Reflectivity is not a cosmetic specification in Climate Zone 2B; it is the primary energy-compliance and membrane-longevity driver, and a scope that leaves it open cannot be evaluated as equivalent across bidders.

We also write the bid form — the table structure that forces all bidders to break out labor, material, insulation, warranty, reflectivity-compliance documentation, and closeout fees as separate line items. This surfaces apples-to-oranges gaps that a lump-sum format conceals and produces a bid tab that a Pima County or TUSD procurement auditor can verify for scope equivalency.

How We Participate as a Bidder

Once the scope document is issued to all bidders, we submit our own bid on identical terms. We do not see other contractors' pricing before finalizing ours. We do not receive first-right-of-refusal or last-look pricing. The bid process is the bid process.

Where we are often useful after bids come back: reference checking on contractors the owner does not know. Tucson's commercial roofing market includes a relatively small number of established contractors with full manufacturer credentials and verifiable NDL warranty closeout history, a larger pool of contractors with regional reach but limited Tucson-specific climate experience, and a rotating population of out-of-state contractors who arrive after monsoon events and leave when the volume subsides. We can tell owners which contractors in the bid pool have closed out projects with functioning manufacturer warranties, which ones have warranty-inspection failures in their history, and which ones have limited documented experience with Sonoran Desert thermal cycling and monsoon dry-in requirements.

We do this reference-checking honestly even if the information favors a competitor. Our value in this market is knowing what we know — withholding it to win one bid damages a relationship that is worth more over time.

When Competitive Bid Coordination Makes Sense in Tucson

Projects above roughly $300,000 installed value in the Tucson market almost always benefit from a formal competitive scope process. Below that threshold, the scope-writing overhead can exceed the expected bid savings. For smaller projects, informal references and a written scope the owner drafts with our input often reaches the same place.

Board-governed and public-sector properties require documented competitive processes regardless of project size. Arizona Procurement Code ARS 41-2501 governs state agency roofing procurement. Pima County's procurement policies, TUSD's facilities procurement requirements, and Vail School District's capital project procedures all specify scope equivalency documentation that a properly written bid scope satisfies. We format scope documentation so it works for an internal auditor as well as for the contractors pricing the work. Federal properties — Davis-Monthan AFB facilities, federal courthouse buildings — have separate procurement requirements we can document for as well.

Frequently asked questions

Do you charge for writing the scope document if we don't select you?

No. We write the scope as part of our business development process. If the process results in another contractor winning the project, we have built a relationship with an owner who ran a credible process and knows we participated honestly. Over time that is worth more to us than a single project fee.

How do you prevent the scope from favoring your preferred membrane or manufacturer?

We specify by performance requirement wherever possible — minimum membrane thickness, minimum solar reflectance (SRI value), minimum R-value, minimum wind-uplift rating, warranty term — rather than by manufacturer name. When a manufacturer must be named for warranty inspection eligibility, we list all manufacturers that

Can we use a scope you wrote if we decide to sole-source the project?

Yes. Some owners use the scope-writing engagement to produce a specification they then use in owner-direct negotiations with a single contractor. The scope document is yours. We retain no intellectual property interest in a roofing scope we produce for your building.

How do you handle bid evaluation when the bids come back?

We walk you through the bid tab line by line, flag scope exceptions where a bidder deviated from the specification, and flag unbalanced bids where a contractor low-bids base work but prices allowance items — insulation replacement, deck repair, drain replacement — at rates that more than recover the discount. We do not vote on a winner. We give you the analysis and you make the call.

Need a bid-ready scope for your Tucson commercial roof project?

We will walk the roof, write the scope document to competitive-bid standard — including IECC reflectivity compliance and monsoon dry-in sequencing requirements — and submit our own bid on equal footing. Whether we win the work or not, you get a defensible process.
