Using the Three-Bid Decoder

This paving bid comparison tool helps property managers slow down the decision before price becomes the only thing anyone sees. Entering three contractor proposals side by side makes scope gaps easier to discuss: base repair allowances, asphalt thickness, tack coat, milling, drainage correction, striping, ADA responsibility, schedule, warranty exclusions, and cleanup are all part of the real value of a bid. A low number can still be expensive if the useful life is short or if critical work is excluded. Use the result as a board memo starting point, then ask each contractor to clarify missing assumptions in writing before approval.

For best results, save the output with dated site photos, the contractor proposal, and any board or owner notes. That documentation makes it easier to compare options, explain tradeoffs, and revisit the decision later if conditions, pricing, tenant needs, or ADA exposure change.

Bid comparison documentation checklist

Before entering numbers, make sure each paving bid is describing the same project. One proposal may include base repair, milling, tack coat, striping, ADA stalls, and traffic control while another lists only an overlay. Those bids are not comparable until exclusions and assumptions are clarified.

Useful life is the missing number in many bid comparisons. Ask each contractor how long the proposed treatment should last if the lot is used and maintained normally. Then compare annualized cost, not just total price. A higher bid with a longer service life can be the lower-cost option over time.

Save the output with the original proposals and clarifying emails. The best bid file shows the board or owner exactly how the recommendation was made: scope completeness, lifecycle value, contractor risk, warranty strength, and open questions.

Use this page together with field photos, contractor notes, budget history, and owner or board priorities. The more complete the project file is before bids are approved, the easier it is to defend the final scope, schedule, and cost.

Before using this tool: If the lot condition and likely repair path are still unclear, start with the Parking Lot Pavement Assessment Guide.
▎About this tool

The Three-Bid Decoder translates raw contractor bids into a side-by-side comparison that actually makes sense. Enter the bid total, useful life estimate, and scope details for up to three contractors — and get cost-per-year-of-useful-life, a scope gap analysis, and a risk ranking. Use it before signing any contract to make sure you're comparing equivalent work, not just sticker prices. Built for property managers, HOA managers, and facility directors who handle regular paving decisions.

▎Common questions

Why shouldn't I just pick the lowest paving bid?

The lowest bid often omits critical scope — base repair, proper compaction depth, joint sealing, or adequate mobilization and cleanup. A bid that skips these items can result in pavement that fails in 3–5 years instead of 12–15. Comparing cost-per-year-of-useful-life reveals when the "cheapest" bid is actually the most expensive decision over time.

What does cost-per-year-of-useful-life mean in a paving bid?

It's the bid amount divided by the contractor's estimated useful life for that scope. A $60,000 bid with a 15-year life costs $4,000/year. A $45,000 bid with an 8-year life costs $5,625/year. The cheaper upfront option is actually more expensive annually — and requires another capital event sooner. This tool calculates that number automatically.

What scope gaps should I look for in a paving bid?

Watch for missing base repair line items, vague thickness specifications (2" vs 3" compacted), no mention of tack coat or bond coat, undefined mobilization and traffic control, no warranty clause, and unclear ADA compliance responsibility. If two bids look similar in price but one has three times the line items, the shorter bid is almost certainly missing scope.
