The spec and the drawings contradict each other
Material, colour or thickness differs between the article and the sheet. Whoever prices the wrong one carries the difference.
A takeoff measures. Modou works out what to buy. The hours and the mistakes sit in documents that disagree and in what the drawing leaves out. That is what Modou reads for, all the way to the materials you order.

Three places the hours and the mistakes hide, and why a takeoff does not catch them.

Material, colour or thickness differs between the article and the sheet. Whoever prices the wrong one carries the difference.

Subframe, flashings, corner pieces, fixings, finishing. A takeoff counts square metres. Nobody counts these until the site does.

A new drawing revision, a price change, a question from the client. Each one reopens a quote, and a day a week goes to revisions.
Each of these programs does its own part of the work well. Modou does the part in between: reading the project documents and working out what to include.
Model checking
Marking up and measuring drawings
Estimating and business administration
Reading project documents
Modou reads the whole tender package and works out the quantities and the materials to order. Every assumption waits for your approval, and it never sends a quote or a question on your behalf.
Batten centres, an allowance per opening, screws per crossing. Every assumption waits for your approval, and each line that depends on one stays provisional until you give it.
Every quantity and every requirement points to its document, page and revision.
Every confirmation, correction and exclusion is kept with your reason, so colleagues can see why. Your own calculation rules apply to every new project.
De Werf façade
Spec article 31.21.10-a says RAL 7016, drawing 04 rev C says RAL 9007.
Hi Mark, the spec and drawing 04 rev C give different colours for the façade panels. Which one leads?
Approved and noted. You send the question to Mark yourself. The panel colour stays open until he answers.
