Why a Document Review Comes First
A construction document set is a contract. The drawings show what to build, the specifications describe how, and the general conditions set the rules for the whole job. When those pieces disagree, or when one of them is silent on something the work clearly needs, the gap becomes a risk.
Reviewing the documents up front is how you find those gaps while they are still cheap to resolve through a question, rather than expensive to fix in the field. The review also protects your bid. An estimate is only as accurate as the scope behind it, and scope lives in the documents.
If you price what you assume rather than what the documents actually require, you will either bid too high and lose the job or bid too low and lose money on it. A disciplined read is the cheapest insurance an estimator can buy. It is the foundation that the rest of the construction estimating process is built on.
Reviewing the Drawings
Start with the cover sheet and drawing index, then confirm you actually have every sheet the index lists. A missing structural or mechanical sheet is a common and dangerous oversight. Check the revision clouds and the dates so you are reading the current issue, not an outdated set, and confirm you have logged every addendum that has been released.
Move through the disciplines in order, architectural, structural, civil, mechanical, electrical, and plumbing, and look for places where one discipline depends on another. A duct that has no room in the ceiling, a footing that lands on a buried utility, or a wall type that does not match between plan and detail are the kinds of coordination clashes that surface only when you read across the set rather than down a single sheet. Accurate measurement from these same sheets is where focused takeoff specialist support pays off.
Pay special attention to general notes, legends, and keynotes, since these often carry scope that never appears as a drawn object. A single note can add fireproofing, a sealant, or a testing requirement to the whole project. Cross reference the schedules too, because door, window, finish, and equipment schedules frequently hold quantities and specifications that the floor plans only hint at.
Reviewing the Specifications
Specifications describe quality, materials, and execution, and they are usually organized by the divisions of the MasterFormat system published by the Construction Specifications Institute. Skim Division 1, the general requirements, first, because it governs submittals, allowances, alternates, unit prices, and quality control for every other section. Many estimating surprises hide in Division 1 rather than in the trade sections.
Read for the small words that carry big cost. Phrases like provide and install, by others, or as required quietly assign or remove scope. Watch for proprietary product callouts, approved equal language, and any required testing, mockups, or commissioning, all of which add cost that the drawings may not show.
Note every allowance and every alternate so your bid form matches what the documents ask you to price. Finally, reconcile the specifications against the drawings.
When a drawing and a specification conflict, the contract usually sets an order of precedence, but you still need to flag the conflict as a question rather than guess. A clean log of these discrepancies becomes the basis for the requests for information you submit during bidding.
The Working Checklist
The table below distills the review into a checklist you can run on every set. Treat it as a minimum rather than a ceiling, and adapt it to the project type, since a hospital fit out and a parking structure stress different items. The goal is consistency, so that the same careful read happens whether you are pricing the job yourself or handing the takeoff to a teammate.
Keep a written log alongside the checklist. Record every gap, conflict, and assumption with the sheet or section number where you found it, so questions can be issued precisely and your final estimate can note exactly what was and was not included. That paper trail is invaluable if the scope is challenged after award.
If your team needs experienced eyes to run this review on every bid, a dedicated construction cost estimator can own the document read and the question log from start to finish. A checklist captures the what.
The how, meaning the order and rhythm of a thorough read, is worth understanding too. Our companion guide to the document review process walks through the step by step workflow that turns this list into a repeatable habit, with discipline coordination standards echoed by the cost engineering community at AACE International.
| Area | What to confirm |
|---|---|
| Drawing index | Every listed sheet is present and is the current revision |
| Addenda | All issued addenda are logged and incorporated |
| Discipline coordination | Architectural, structural, and MEP sheets agree with each other |
| General notes and keynotes | Scope carried only in notes is captured |
| Schedules | Door, window, finish, and equipment schedules are reconciled |
| Division 1 | Allowances, alternates, unit prices, and submittals are noted |
| Specs versus drawings | Conflicts are flagged as questions, not assumptions |
| Question log | Every gap is recorded with its sheet or section reference |
