What’s inside a construction estimate
What each line actually means, and where hidden costs usually hide.
Daniel Moore
Head of Estimating
How an estimate is structured
An estimate is the foundation of your contract price. It is usually split into sections: site preparation, groundworks, frame, roof, building systems, finishing and landscaping. Each section lists the volume of work, the unit price and the total.
A good estimate reads like a map of the project. If you can’t tell from it what will be built and in what order, ask for a more detailed breakdown before you sign anything.
Labor and materials
A reliable estimate shows labor and materials as separate lines. That way, if you switch to a different tile or window brand, you immediately see how the price changes, and nobody can quietly move costs between the two.
“An estimate that lumps labor and materials into one line is the easiest place for the price to grow later.”
Costs that often go missing
These items are frequently left out of the first estimate:
Geotechnical report and plan review fees
Utility hookups and tap fees
Construction waste removal
Temporary power and water on site
Equipment rental and delivery
A quick checklist
Are labor and materials priced separately?
Are material brands and grades specified?
Is the price stated as fixed in the contract?
Who pays for the five items listed above?
