Biddu Book a diagnostic
Financial intelligence and AI for construction companies

Bid with numbers you can defend.

We help contractors find the right projects, quantify from the drawings, build the bid, schedule the work and finance it. Every figure comes from an auditable engine: you see where it came from, which assumption it rests on, and how confident it is.

Traceable to the drawing

Every quantity carries its method, source sheet and confidence level. A reviewer can redo the count without calling you.

Real schedule first, buffer second

Durations come from actual crew hours per stage. Risk buffer is added separately and declared. Nothing gets padded quietly.

Your template, your language

The estimate lands in the workbook you already use, with live formulas, in English or Spanish, in your currency.

Client workspace

This is what a client sees

Open the workspace of a sample tenant, generated by the engine from a real solicitation: project overview, estimate, stage ledger, schedule and the linked 3D model. No install, no account.

We run your bid desk. You sign the number.

Three ways to work with us, from a single bid to operating your preconstruction and financing as an extension of your office.

For subcontractors

Bid Desk

We operate your estimating office. Every week you get the solicitations that fit your trade, size and region. For the ones you pick, we deliver the audited takeoff and the bid in your template, help you submit it and follow up.

  • Weekly list of qualified bids
  • Takeoff, estimate and bid form
  • Submission support and follow-up
  • Real schedule with declared buffer
Per bid or monthly retainer
For general contractors

Preconstruction Office

We operate your preconstruction accounts. We list and qualify projects, level subcontractor bids, build the master schedule and the cash plan, and run stage control once you are on site.

  • Project pipeline and go/no-go
  • Sub bid leveling and scope gaps
  • Master schedule and crew plan
  • Stage ledger: bid versus actual
Monthly retainer per account
For both

Capital Desk

Financing that follows the schedule. We build the funding package from the stage ledger and present it to lenders and banks: working-capital lines, equipment and project financing, bonding readiness, draw schedules.

  • Cash plan by stage and payment terms
  • Lender and bank package
  • Bonding and prequalification files
  • Margin, backlog and cash strategy
Success fee or advisory retainer
How it works

From the bid notice to cash flow, one chain

Six stages, one team, one data model. What gets measured in the takeoff is what gets priced, scheduled and controlled on site.

01

Find the right bids

We screen public and private solicitations against your real capacity: trade, size, region, bonding, expected margin. You pick which ones to pursue.

Team + AI
02

Audited takeoff

Quantities from drawings and models. Each item shows method, source sheet and confidence so a reviewer can rebuild it.

Engine
03

Estimate and bid

Labor hours, material, equipment, indirects and bid layers (contingency, insurance, bond, escalation) in your estimating template.

Engine
04

Real schedule

Stage and crew durations from actual hours, with the risk buffer kept separate and explicit. No inflated dates without a reason.

Engine
05

Financing

Disbursement curve by stage, working-capital need and financing options with lenders and banks so you never run dry during rough-in.

Team + AI
06

Stage control

A ledger by stage and trade: bid versus actual, with alerts when a line drifts.

Engine
Deliverables

What you get for every project

Files that open without installing anything. The numbers match across all of them.

Estimate workbook

Excel with live formulas, not pasted values: bid form, takeoff and scope, line detail with basis and confidence, summary, exclusions, audit log, stage-by-trade ledger with built-in reconciliation checks.

Project dashboard

One page per project: stage flow with prerequisites, cost by stage, day-by-day timeline and the warnings to clear before you sign. Works offline. English and Spanish.

Linked 3D model

Every element knows its stage, crew and cost. Filter by level or trade, switch to plan view, measure, and play the build day by day with cumulative hours and cost.

Bid portfolio

All active bids in one comparable table: bid, direct cost, hours, days, buffer and warnings. Decide where your team goes next.

Cash plan

Disbursements by stage against the contract's payment schedule. Where capital is needed, how much, for how many days.

Validation report

Comparison against your historical references with every difference explained. If a number does not reconcile, we say so and say why.

Principles

How we treat the numbers

AI speeds up the work. Estimators set the rules. A deterministic engine checks them: same input, same result, every time.

01 / Real data only

Nothing invented

Your drawings, your rates, your history. A missing input shows up as a warning, never as a convenient number.

02 / Real before buffer

Padding is declared

Duration is computed from crew hours. Risk buffer is a separate, visible line. Nobody inflates the schedule in the dark.

03 / Traceability

Every figure has a path

Quantity, sheet, method, confidence. Cost, rate, factor, layer. An outside reviewer can rebuild the calculation from what we hand over.

04 / Your office, not ours

We adapt to your format

Your estimating template, your currency, your language. The engine fits your workflow instead of replacing it.

The pilot

Three weeks to your first defensible bid

We start with a live solicitation of yours, not a demo. At the end you have a bid ready to sign and the method installed in your team.

Week 1

Diagnostic

We review how you bid today: templates, rates, history, where margin leaks. Together we pick the pilot project.

Week 2

Pilot build

Audited takeoff, estimate in your template, real schedule with explicit buffer and the project dashboard. You review every warning.

Week 3

Handover

Bid ready to sign, cash plan and portfolio. Your team keeps the process and the tools for the next project.
