A price is only comparable when the scope is comparable. Before ranking totals, make sure each proposal describes the same area, existing-condition assumptions, base work, surface construction, drainage, access, and completion standard.

Step 1: write a one-paragraph project brief

Include:

Send the same brief and the same site photos to every bidder. If the scope changes after one site visit, issue the clarification to everyone still being compared.

Step 2: measure and map the work

Create a simple plan with length and width by zone. Mark buildings, garages, sidewalks, curbs, property lines, drains, downspouts, utility covers, trees, gates, steps, and transitions.

For irregular areas, divide the surface into rectangles and triangles. Measurements are for comparison and planning; the contractor remains responsible for any quantity represented in its proposal unless the contract says otherwise.

Use separate zones for:

Step 3: record the existing condition

Use the damage guide for consistent symptom language. Avoid diagnosing hidden layers from appearance alone.

Step 4: make every proposal answer the same scope questions

Removal and preparation

Base and drainage

Asphalt option

Concrete option

Operations and closeout

Step 5: separate fixed scope, allowances, and unit prices

An allowance is not the same as a fixed inclusion. For uncertain work, ask for a clear trigger and unit price—for example, additional excavation, granular material, concrete removal, utility adjustment, or traffic-control time.

A useful change process states:

  1. how the hidden condition is documented;
  2. who may authorize extra work;
  3. how price and schedule impact are calculated; and
  4. that approval occurs before the extra work, except for immediate safety needs.

Step 6: compare the contractor, not only the construction line

Depending on project size and procurement requirements, review:

Do not treat one credential as proof of every capability. Match experience and documentation to the actual project.

Common warning signs

One warning sign is a prompt for clarification, not automatic proof of bad work. What matters is whether the answer becomes specific and documented.

Step 7: rank value transparently

Create your own weighting before opening final prices. A simple example:

Then compare total price. Change the weights to suit the project, but do it deliberately so a polished sales conversation does not erase a major scope gap.

Keep the final documents together

The signed scope, drawings, clarifications, change orders, site photos, material tickets, test results, opening instructions, warranty, and maintenance requirements become the baseline for future inspection and repairs.
