The Friday tender

A tender lands Friday at four. Forty sheets, three revisions, due Tuesday.

An estimator at her desk on a Friday afternoon, surrounded by roof drawings. Fri 16:04
Hours of clicking

Your estimator traces every roof field, edge and upstand by hand, sheet after sheet.

One missed revision

A newer drawing changes the roof. The quote still has the old square metres.

Margin on the line

A wrong number goes out under your name. You find out on the roof.

Roof Companion does the counting. Your estimator does the judging.

How it works

Four steps from tender set to quote.

No new way of working. Roof Companion follows the steps your estimator already takes, only faster, and shows its work.

  1. Drop the drawings

    The whole tender set: roof plans, details, sections, the BIM model, your Bluebeam markups. It finds the roof sheets itself.

  2. It measures

    Calibrates the scale from the dimension chain, splits roof levels, measures net areas, edges and upstands, and counts outlets and hatches from the legend.

  3. You check

    Every line is tagged with where it came from. Anything uncertain says CHECK. Fix a contour with one click and everything after it recalculates.

  4. Send the quote

    In your own layout, with your own prices and labour norms. Internal costs and margins never reach the customer version.

What you get

One drawing set. Four documents.

All from the same measurements, so they always agree with each other.

For you & the client

Roof overview

Your own drawing, like an architect makes it: the measured roof, dimensions, your legend and your logo in the title block.

Internal

Takeoff sheet

Every quantity with its source and nothing else. The sheet your estimator checks before a single euro is added.

Internal

Calculation

Material, labour hours, equipment and margin per roof part. Built from your rate card. Never sent to the client.

For the client

Quote

Per roof part, in your house style. Options and exclusions included, internal numbers left out.

Why you can trust it

It never guesses.

Language models are bad at measuring, so they don't measure here. Geometry is measured by code on the calibrated drawing. AI reads the labels and legends and double-checks the counts.

When the scale or a contour can't be verified, you get “calibration needed” instead of a number. Unknown is never zero.

Prices come only from your own rate card or supplier quotes. If there is no price, the line stays open.

SOURCE

Read from the drawingTaken verbatim, like a count or a product from the legend.

MEASURED

Measured on the drawingArea or length from the calibrated geometry.

CALCULATED

DerivedWorked out from measured values, like insulation volume.

CHECK

Needs a humanMissing or uncertain. Waits for your call.

70 %

Drawing and BIM model checked against each other.
Every difference is listed. In testing on a real project, this caught a façade line that was about 70% too high before it reached a quote.

Roadmap

It starts with the calculation. Then the rest of the job.

The quote is already almost the order list. Each step builds on the same measurements.
