Built for the contractors who live in the dirt.

Generic construction bidding tools weren't built with your equipment rates, crew structures, or material reality in mind. Excavation Expert is.

Site Work & Heavy Civil

Concrete Subcontractors
Flatwork, footings, foundations, ICF, and decorative pours.
Demolition & Dirt Work
Building demo, land clearing, hauling, and material recycling.

Everything you need to bid, win, and deliver.

Bidding software that doesn't stop at the proposal. Won work flows into project management without re-keying a single line.

How the bidding workflow works

1

Receive the RFQ

Log the bid invitation, attach plans and specs, and note the due date. Everything about the opportunity lives in one place.

2

Draft with AI or from scratch

Describe the scope to AI and let it draft line items using your rate library — or build the bid manually with clone-from-past-project shortcuts.

3

Review the numbers

Adjust quantities, rates, markup, and contingency. See live margin as you change inputs. Catch thin spots before the customer does.

4

Send a professional proposal

Generate a branded PDF or share the secure portal link. Customer can approve online — you get notified the moment they do.

5

Convert won bids to projects

One click moves the scope, schedule, resources, and financials into an active project — no double entry.

Frequently asked questions

What is the best bidding software for excavation contractors?

Excavation Expert is purpose-built for excavation, site work, and heavy civil contractors. It combines AI-assisted estimating, line-item takeoffs, crew and equipment rates, and a customer approval portal in one platform — so you can go from RFQ to signed bid without switching tools.

How does construction bidding software save time?

Good bidding software eliminates duplicate data entry between spreadsheets, takeoff tools, and proposals. Equipment rates, labor burden, and material pricing are stored once and reused on every bid. AI assistance drafts the initial line items in seconds, turning a multi-hour exercise into a review-and-adjust workflow.

Can I send bids to customers electronically?

Yes. Bids generate as branded PDF proposals and are shared through a secure customer portal. Customers can review line items, ask questions, and approve the bid online — with every interaction logged on the project record.

Does bidding software work for small contractors?

Yes. Pricing starts with a free tier that includes bid management and the Ask AI assistant. Paid tiers add AI bid generation and higher usage limits, so a one-person shop pays a very different price than a 50-person crew.

What does excavation bidding software typically include?

Core features include line-item estimating, equipment and labor rate libraries, material cost tracking, bid versioning, PDF proposal generation, customer approval workflows, and conversion from won bid to active project. AI-assisted drafting and integrations with accounting tools like QuickBooks are increasingly standard.
