Before you bid
- Registration and prequalification. KDOT generally requires prime contractor prequalification. Some owners require vendor registration or bidder prequalification forms. Local contractor licensing may also apply.
- Bonding capacity. Confirm your surety can support the bid amount.
- Plan room access. Download the complete set, including the project manual, and register as a plan holder so you receive addenda.
- Pre-bid meeting. Some meetings are mandatory; missing one can disqualify your bid.
Read the instructions to bidders
The instructions to bidders and Division 00 documents control everything about how the bid must be submitted:
- Bid form, unit prices, alternates and allowances.
- Bid security amount and form.
- Required attachments: subcontractor lists, certifications, affidavits.
- Submission method, location and deadline.
- Questions deadline and how addenda are issued.
Pricing items unique to public work
Bonds
Price performance and payment bonds based on your surety's rate schedule. Kansas law requires payment security on most public works contracts, and owners specify bond forms.
Sales tax exemption
Kansas exempt entities can obtain a Project Exemption Certificate (PEC) that exempts materials and labor. Price tax-exempt only when the documents confirm a PEC, and make sure materials are not purchased before the certificate's effective date. See the Kansas contractor sales tax guide.
Prevailing wage
State and local projects generally do not require prevailing wages because Kansas repealed its law in 1987, but federally funded work requires Davis-Bacon wages and certified payroll. See prevailing wage in Kansas.
Storm shelters
New K-12 schools in Kansas jurisdictions on the 2015 or later IBC generally require ICC 500 storm shelters, a major structural and envelope cost. See estimating ICC 500 storm shelters.
Payment terms and retainage
Kansas fairness-in-construction statutes require owners to pay undisputed requests within 30 days, cap retainage at 5% (10% maximum) and require release within 30 days after substantial completion. Price the carrying cost of retainage on long projects. See Kansas prompt payment and retainage laws.
Unit-price and KDOT bids
Highway and utility work is bid by unit price against the owner's estimated quantities. Check quantities against the plans; when you find significant discrepancies, submit a question before the deadline. Balanced unit prices protect you if quantities change, while heavily unbalanced bids can be rejected. See sitework estimating.
Bid-day execution
- Set up the bid form and spreadsheet in advance with plug numbers for every scope.
- Level subcontractor bids against your scope sheets.
- Acknowledge every addendum.
- Have bid security, signatures and attachments complete before final pricing.
- Leave time for delivery or upload; late bids are rejected.
Our public works bid estimating service prepares estimates organized to the owner's bid form, with scope sheets for subcontractors. Contractors in Topeka use it for state and municipal bids. See also the general Kansas construction bid checklist.
Frequently asked questions
Where do I find public construction bids in Kansas?
On owner websites for cities, counties, school districts and universities; in regional plan rooms and bid services; through the Kansas Department of Administration for state building projects; and through KDOT's lettings for highway and bridge work.
Do I need to be prequalified to bid KDOT projects?
KDOT generally requires prime contractors to be prequalified before bidding its lettings. Check KDOT's current prequalification requirements and allow time for approval before the letting you want to bid.
Are bonds required on Kansas public projects?
Most Kansas public owners require a bid bond or bid security with the bid, commonly 5 percent, and performance and payment bonds on award. Kansas law requires payment bonds on most public works contracts so subcontractors and suppliers are protected. Confirm thresholds and forms in the instructions to bidders.
Why are public bids rejected?
Common reasons are late submission, missing bid security, unacknowledged addenda, incomplete bid forms or unit prices, missing required certifications or subcontractor lists, and math errors on unit-price bids.
