Design & Plan Review
An independent, experienced set of eyes on your drawings, specifications and scope — catching conflicts before bid day saves far more than any last-minute correction ever can.
A set of construction drawings is a promise: build this and you will get the building that was designed. But every set of drawings also carries risk — details that are missing, dimensions that conflict, specifications that contradict the drawings, scopes that fall between two trades with nobody claiming responsibility. Those gaps exist on every project. The question is whether they are found during a structured review before anyone bids or builds, or whether they are found in the field where a change order costs ten to fifty times more to fix than a redraw.
CEDS Estimating provides independent design and plan review services for contractors, subcontractors, developers, architects and owners who need a qualified reviewer to examine their drawings and specifications with a constructability lens. Our reviewers read drawings the way a contractor reads them — not as design theory but as a set of instructions for physical work — and they identify the issues that a tradesperson would discover on day one of construction if nobody caught them first.
The review is not a code review and it is not a design critique. It is a practical, construction-focused evaluation of whether the drawings and specifications can be built as shown, whether the scope is complete enough to price accurately, and whether the different trades are coordinated so their work does not collide. The result is a severity-ranked findings report that the project team can act on immediately — fixing the items that would cause the most damage before they cause any damage at all.
The economics of a plan review are easy to understand from a contractor's side: an hour spent reviewing the set before the bid is worth ten hours of change order administration after award. A field change discovered during construction carries the cost of the rework itself, the schedule delay that comes with it, the back-charge negotiation and the documentation that accompanies every change. A review finding, by contrast, costs only the drawing time to fix the issue — and there is no field labor, no delay and no dispute attached to it. Every finding the review catches before bid day is money that stays in the project instead of leaking out through rework.
The same logic applies to owners and developers. An owner who submits an un-reviewed drawing set to three contractors gets three bids built on three different sets of assumptions about the missing information. An owner who reviews the set first gets three bids built on the same, corrected scope — which makes the comparison meaningful and the award defensible. Plan review is not an extra step on the path to construction; it is the step that protects the value of every step after it.
Buildability & Constructability
Buildability review answers one question: can this building actually be constructed as the drawings describe it? This is not a theoretical exercise. It requires reading every structural member against the architectural intent, checking that mechanical equipment fits in the spaces provided, verifying that steel connections are accessible with a wrench and confirming that the sequence of construction described by the drawings is physically possible.
Buildability & Constructability
Reviews structural members, framing connections, mechanical clearances and construction sequencing to confirm the building can physically be assembled as the drawings describe. Identifies impossible connections, inaccessible equipment locations and construction sequence conflicts before the contractor discovers them in the field.
Specification Compliance
Cross-references the written specifications against the drawings to confirm they describe the same scope. Identifies specifications that reference discontinued products, codes that have been superseded, fire ratings that contradict the drawing notes and material requirements that conflict between the spec sections and the drawing callouts.
Bid-Set Completeness
Evaluates whether the drawing set is complete enough for a contractor to price the work without making assumptions. Identifies missing details, undefined scope areas, unpriced alternates and incomplete trade boundaries that would force a bidder to include contingencies instead of hard numbers.
Trade Coordination
Checks whether the architectural, structural, mechanical, electrical and plumbing drawings align on the same grid, reference the same datums and do not conflict at intersections. Identifies clashes between trades that would require field coordination or rework if not resolved on paper first.
Alternate & Allowance Review
Reviews the alternate and allowance structure to confirm each item is clearly defined, priced at a reasonable range and scoped so a bidder can respond to it without ambiguity. Identifies alternates that are too vague to price and allowances that are unrealistic for the specified product level.
Design-to-Budget Alignment
Compares the design scope and specification level against the project budget to identify elements that are under-budgeted, over-specified or missing from the cost model entirely. This early-warning check prevents the budget from collapsing under scope that was designed but never priced.
Red-Flag Checklist
The checklist below identifies the most common categories of issues found during a CEDS plan review. These are not edge cases — they appear on nearly every set of construction drawings reviewed, regardless of project type or size. Catching even half of these before bid day dramatically reduces the number of RFIs, change orders and delays that erode project margins.
- Dimensions that do not add up across related sheets
- Window and door schedules that do not match the floor plans
- Wall types referenced on plans but not defined in the wall-type schedule
- Structural beams sized without architectural clearance confirmation
- Mechanical equipment specified in spaces too small for service access
- Fire-rated assemblies that do not match the code-required rating
- Specifications referencing products that have been discontinued
- Trade scope gaps where two trades assume the other is responsible
- ADA accessibility clearances not verified against the floor plan
- Energy code requirements not addressed in the insulation or glazing notes
- Alternates described vaguely enough that a bidder cannot price them
- Allowance amounts that are unrealistic for the specified finish level
Each category on the checklist is reviewed against the sheet set as a whole, not sheet by sheet in isolation. A dimension that adds up on one floor plan can still be wrong when that plan is read against the section drawing or the structural framing plan. An allowance that looks reasonable against the construction documents can still be unrealistic when compared to the specification's product requirements. The review reads the documents the way the field will use them — as one interconnected set — which is why the findings it produces are the findings that actually matter to construction.
For contractors, the checklist also doubles as a bid-time scope map. Each item that passes review is one fewer assumption your estimate carries and one fewer contingency your bid has to price. Each item that fails is a known quantity you can price deliberately instead of guessing — a coordination issue you can address before award, a spec conflict you can exclude from your bid with a letter, an allowance you can flag in your proposal. A reviewed set converts estimate uncertainty into priced decisions, which is precisely what separates a competitive bid from a hopeful one.
What You Receive
- Findings Report
- A severity-ranked report listing every issue found during the review, organized by category — buildability, specification, coordination, scope, code — with the sheet reference, description and recommended resolution for each finding.
- Red-Line Markup
- A marked-up copy of the drawings showing each finding at the location on the plan where it occurs, so the architect or designer can resolve the issue in context rather than hunting through a written report.
- Review Call
- A scheduled call to walk through the findings with the project team, answer questions and prioritize the issues that must be resolved before bid day versus those that can be addressed during construction.
- Scope Gap Matrix
- A trade-by-trade scope matrix identifying where scope overlaps, where scope is missing and where responsibility falls between two trades with no clear assignment. This matrix is the basis for clean subcontractor scope letters.
- Budget Reality Check
- A comparison of the design scope and specification level against the stated project budget, identifying elements that appear under-budgeted or missing from the cost model, so the owner can adjust the budget or the scope before bidding begins.
Alongside the core deliverables, the review package can include a rescope letter set for the architect, a subcontractor scope-letter matrix for the bid package and a review summary suitable for an owner or lender. The goal is always the same: to move the project from a set of assumptions to a set of decisions. Every finding the review produces has a recommended resolution, every resolution is priced in scope terms, and every issue is either closed before bid day or consciously accepted as a risk with a documented cost. That is the difference between reviewing the drawings and merely reading them.
Caught Before Bid Day, Not on the Jobsite
"We almost bid a medical office TI without a plan review. CEDS found that the HVAC spec referenced a rooftop unit that did not fit the mechanical closet shown on the plans, and the electrical spec called for a 400A service while the floor plan showed a 200A panel. Those two findings saved us at least $18,000 in change orders after award. The plan review paid for itself on the first finding."

Design & Plan Review Questions
General contractors preparing a hard bid, subcontractors evaluating a trade scope, developers validating a design before committing to construction, architects seeking an independent constructability check and owners who want a second opinion before approving a drawing set. If the project involves construction drawings that someone will build from, a plan review adds value.
A code review checks compliance with the building code — egress, fire separation, accessibility, structural loads. A plan review checks constructability — can this actually be built, is the scope complete, are the trades coordinated and are the specifications consistent with the drawings. Both are important, but they catch different categories of problems. A code review protects the building users; a plan review protects the project schedule and budget. CEDS plan reviews focus on the construction and coordination side, with code issues flagged where they directly affect constructability or pricing. If a comment from the building department is awaiting a response, the review also cross-checks the resubmitted drawings against the comment to confirm the fix was actually applied.
A residential plan review — 15 to 25 sheets — takes three to five working days. A light-commercial set — 30 to 60 sheets — takes five to ten working days. Rush review is available for projects on tight bid schedules, with delivery in 48 to 72 hours for sets under 40 sheets. We confirm the delivery date before beginning the review.
Yes. The CEDS review covers the full drawing set — architectural, structural, mechanical, electrical and plumbing. Trade coordination is one of the most valuable aspects of the review, because the most expensive field problems typically occur at the intersections between trades, not within any single discipline.
No. The review is designed to fit within a standard bid schedule without causing delays. Most reviews are completed within the same window that your team is preparing the estimate, so the findings are available before the number goes out. The time saved by avoiding post-award change orders more than compensates for the time invested in the review.
