Practical guidance

Normalize the scope before comparing price

Use the same drawings, quantities, specifications, and owner assumptions.
Add allowances and work you must purchase separately.
Mark exclusions for permits, design, trenching, rock, hauling, disposal, restoration, taxes, or utility coordination.
Compare payment schedule, insurance, licensing where required, references, warranty, schedule, and change-order rules.

Use the same questions

Questions for every bidder

What exact scope and quantity is included?What is specifically excluded?Which allowances can change and how are they reconciled?Who handles permits, design, inspections, utilities, hauling, and disposal?What site condition is most likely to create a change order?What is the payment schedule and what proof is tied to each payment?What warranty and closeout documents are provided?
