Cromwell Design Build

How we work

What owners, consultants and general contractors can expect from us between the invitation to bid and closeout. For one contract that covers the design as well, see design-build.

From invitation to closeout

Seven steps. The first four cost the owner nothing and decide most of what follows.

From tender invitation to closeoutSeven steps in order: invitation, takeoff, questions, bid, award, build and closeout.1InvitationDrawings, specsand closing date2TakeoffQuantities fromthe documents3QuestionsRFIs and addendabefore pricing4BidPrice, inclusions,exclusions, schedule5AwardContract, certificates,start date6BuildSite crew, weeklyreporting7CloseoutDeficiencies, as-builts,warrantiesEstimatingDelivery

What a bid from us includes

A price by scope
Broken down far enough to compare with other bids and to value changes later.
Inclusions and exclusions
Written out, so nothing is assumed by either side.
Clarifications
Any assumption we made where the documents were silent or in conflict.
Addenda
Each addendum acknowledged by number.
Schedule
Durations, crew sizes and the date we can start.
Separate and alternate prices
Where the documents ask for them, or where we see a saving worth showing.

During the work

  1. Start-up

    Contract, insurance and clearance certificates, schedule, safety plan and the list of submittals.

  2. Supervision

    A named supervisor on site whenever our crews or trades are working.

  3. Weekly report

    Work completed, work planned, crew sizes, deliveries, open questions and photographs.

  4. Questions and changes

    Requests for information are logged and tracked. Changes are priced before the work is done.

  5. Inspection and testing

    Hold points are booked ahead, and test results are sent on as they arrive.

  6. Closeout

    Deficiencies completed, as-built drawings, manuals and warranties handed over together.

Payment under the Construction Act

Ontario’s Construction Act sets the timing of payment on construction contracts. We invoice and pay to its terms.

Invoices
Monthly, unless the contract says otherwise.
Payment
Due within 28 days of a proper invoice.
Subcontractors
Paid within 7 days of our being paid.
Holdback
10% retained on each payment, as the Act requires.

Since January 1, 2026, accrued holdback is released every year on longer projects, and an invoice is deemed proper unless the owner objects within 7 days. How the 2026 changes work.

Working with us

How do we add you to a bidders list?

Send the invitation to [email protected] or call (416) 659-8155.

Will you look at a site before pricing?

Yes. For demolition and renovation work a site visit is part of the estimate.

Can you give a budget before there are drawings?

Yes. A budget from a concept or a test fit is stated as a range, with the assumptions behind it.

Tell us about the project.

Design-build briefs, tender invitations, budget requests and site walk-throughs. Tell us the scope, the location and the timing.
