The challenge

When Estimating Becomes the Bottleneck.

Multiple bids. Competing deadlines. A staffing gap. An owner pulling you into estimating. When the team cannot keep up, estimates get rushed — or opportunities get left behind.

The outcome

Add Capacity Without Losing Control.

  • Keep priority estimates moving
  • Reduce pressure on internal staff
  • Get clearer quantities, assumptions and pricing basis
  • Make bid and cost decisions with greater confidence

Frequently Asked Questions

View all FAQs
What do you need from us to get started?

The drawings, specifications and addenda you have so far, plus the bid deadline. Partial sets are fine; we’ll flag what’s missing.

How do you determine turnaround time?

Turnaround depends on project size, level of detail and document completeness. We confirm a delivery date before starting.

How do you handle incomplete drawings or scope?

We document assumptions clearly, price what is shown, and call out gaps so you can decide how to treat them in your bid.

Can you work alongside our internal estimator?

Yes. We can take specific packages, provide a second review, or fill in during peak periods, whichever helps most.

How do you document assumptions and exclusions?

Every estimate includes a written list of assumptions, clarifications and exclusions so your team and your client know exactly what is covered.

What types of projects do you estimate?

Commercial, multifamily, institutional and light industrial work, from tenant improvements to ground-up construction.

Can we start with one project?

Absolutely. Many clients start with a single estimate to see how we work before setting up ongoing support.

How is pricing determined?

Pricing is based on project size, scope and required level of detail. You’ll receive a fixed quote before we begin.
