Eliminate Costly Change Orders Before Bidding
In commercial construction, profit margins are rarely lost to bad pricing—they are lost to uncaptured scope, design discrepancies, and uncoordinated trade hand-offs. A missing steel embed, an unpriced soffit extension, or a spatial conflict between HVAC ductwork and structural framing can result in severe delay claims and budget overruns during active field operations.
Our specialized Constructability Review & Scope Gap Analysis service bridges the gap between design intent and field execution. By conducting exhaustive preconstruction plan audits before bids are finalized, Design Estimation equips Commercial General Contractors and Owners with an actionable RFI log and scope verification matrix that stops costly change orders before ground is broken.
Key Preconstruction Audit Focus Areas
Inter-Disciplinary Discrepancy Audits
Cross-checking architectural elevation sheets against structural framing plans and MEP riser diagrams to flag dimensional mismatches, ceiling plenum head-room conflicts, and misaligned utility penetrations.
Subcontractor Scope Gap Detection
Auditing grey-area trade hand-offs (e.g., steel embeds in concrete, structural backing for equipment, flashing behind siding, waterproofing terminations) to ensure no scope drops between sub-trades.
Specification vs. Plan Reconciliation
Reconciling project manual specifications (CSI Divisions 1–33) directly against sheet schedules and details, catching unpriced performance standards or missing equipment requirements.
Site Logistics & Constructability Analysis
Evaluating material staging zones, crane access clearances, long-lead equipment placement, and installation sequencing to prevent operational bottlenecks on tight commercial jobsites.
Our 4-Step Review Process
Plan Ingestion & Alignment
Drawing sets, specifications, and addenda are ingested, organized by trade discipline, and verified for revision currency.
Cross-Trade Plan Audit
Senior estimators perform multi-layered plan overlays, checking load paths, dimensional gridlines, and clearance spaces.
Scope Gap Identification
Unassigned scope, conflicting details, and missing specifications are compiled into a structured pre-bid RFI log.
Mitigation Report Delivery
Client receives a comprehensive constructability matrix with specific recommendations for bid inclusions and trade scope sheets.

Technical Plan Check & Review Matrix
| Discipline Interface | Constructability Audit Focus Areas |
|---|---|
| Architectural / Structural | Expansion joint alignment, structural support for curtain walls, bearing wall locations vs floor plans, floor slab depression details. |
| Structural / MEP | Ductwork/conduit penetrations through structural beams/shear walls, mechanical pad structural support, ceiling plenum clearance audits. |
| Architectural / MEP | Diffuser/fixture locations vs reflected ceiling plans, wall rating penetrations, ADA clearance for wall-mounted electrical panels/fixtures. |
| Civil / Structural / MEP | Invert elevations at building footprint boundaries, foundation conflicts with underground utility lines, stormwater detention tie-ins. |

Constructability Review Questions
Answers to the questions clients ask most before sending us their project.
Are Constructability Reviews Done by AI or Human Estimators?
Our constructability reviews and scope gap analyses are performed by experienced human estimators. We use professional software to organize drawings and quantities efficiently, while our reviewers check drawings, specifications, trade scopes, and coordination issues before finalizing the report.
What is a constructability review?
It's a detailed check of the bid documents before you price the job. We look for conflicts between drawings and specs, missing details, scope gaps between trades, and anything that's going to turn into an RFI or a change order later.
When is the best time to run a review?
As early as possible, ideally during bidding or right after award. Problems found on paper cost you a phone call. The same problems found in the field cost you crew time, rework, and schedule.
What do I get at the end of the review?
A written list of issues organized by sheet and discipline, each with a short explanation and a suggested question or clarification. You can turn most of them straight into pre-bid RFIs or exclusions.
Is this only for general contractors?
No. Subcontractors use it to find scope that's shown on another trade's sheets, or work the specs assign to them that the drawings barely show. It's one of the best ways to avoid buying work you didn't price.
Can you combine the review with an estimate?
Yes, and it works well. Our estimators find most gaps naturally while doing the takeoff, so pairing the two gives you a cleaner number and a list of what to clarify before you submit.
