How to set up a plan review workflow

Create a systematic process for reviewing construction documents.

Ad-hoc plan review leads to missed issues, duplicated effort, and inconsistent quality. A structured workflow ensures thorough review, clear accountability, and documented findings. Here's how to set one up.

Step 1: Define Review Types and Triggers

Different milestones require different review depths:

SD (Schematic Design)High-level

Program fit, major code issues, site constraints

DD (Design Development)Moderate

Coordination, constructability, value engineering opportunities

50% CDDetailed

Detailed coordination, specification alignment, scope gaps

100% CD / IFCComprehensive

Completeness, dimension verification, final QC

Addenda/RevisionsTargeted

Change impacts, coordination with existing work

Step 2: Assign Review Responsibilities

Divide review tasks by expertise:

This split works best when supported by role-specific workflows for general contractors, estimators, and discipline leads.

Project Manager

Scope alignment, contract compliance, cost implications

Superintendent

Constructability, sequencing, site logistics

Estimator

Scope changes, quantity verification, specification alignment

MEP Coordinator

System coordination, clash detection, routing

Safety Manager

Access, fall protection, hazardous conditions

Step 3: Create Standard Checklists

Checklists ensure consistent, thorough reviews:

General: Sheet organization, revision control, scale verification
Architectural: Code compliance, dimension verification, finish schedules
Structural: Grid alignment, member sizing, connection details
MEP: Coordination, equipment schedules, routing conflicts
Site: Utilities, grading, access, staging areas

Customize checklists based on project type and lessons learned from previous projects.

Step 4: Set Up Document Management

Organize files for efficient review:

1.Store drawings in a central, version-controlled location
2.Use consistent naming conventions (Project_Discipline_Date_Rev)
3.Maintain separate folders for each review milestone
4.Keep marked-up copies separate from clean originals
5.Archive superseded versions for reference

Step 5: Establish Comment Standards

Consistent comment format speeds resolution:

Comment Format

Location: Sheet, grid lines, room number

Issue: Clear description of the problem

Severity: Critical / Major / Minor

Suggested Resolution: Proposed fix if known

Reviewer: Initials and date

Step 6: Define the Review Cycle

Set clear timelines and handoffs:

Receipt

Log drawings, notify reviewers, set due dates

Distribution

Send to assigned reviewers with checklists

Individual Review

Each reviewer completes their discipline review

Consolidation

Compile all comments, remove duplicates

Review Meeting

Discuss critical issues, prioritize responses

Transmittal

Send consolidated comments to design team

Tracking

Monitor responses, verify resolution

Step 7: Track and Measure

Metrics help improve your process:

Number of issues found per review phase
Critical issues caught vs. missed (found later)
Average review turnaround time
RFI rate after each review milestone
Cost of issues caught early vs. in field

For rollout planning, align feature priorities in the comparison hub and finalize access strategy on the pricing page.

Practitioner insight

“We used to treat the GC plan review as a one-pass thing at 90 percent CDs. Once we split it into 60 percent and 90 percent passes with the same checklist, the 90 percent review went from 'find a hundred things at the last minute' to 'verify the dozen things we flagged at 60 are resolved'. The schedule pressure dropped at the worst phase of the job.”

Conversations with preconstruction managers and VDC leads at mid-market commercial GCs running 60% and 90% internal plan reviews on $20M–$80M projects.

Frequently Asked Questions

What is a construction plan review workflow?

A construction plan review workflow is the structured internal review process, phases, checklists, reviewers, sign-offs, and tracking, that a project team runs on its own drawings before they reach permitting, bid, or the field. It's distinct from the AHJ plan check (which is the permit authority's review) and from a designer's QA/QC (which is internal to the design firm). Its goal is to catch coordination conflicts, code compliance gaps, and scope ambiguity while changes are still cheap.

At what design milestones should you run a plan review?

Most general contractors and construction managers run reviews at the same design milestones the architect or engineer issues: schematic design, design development, 60% construction documents, 90% construction documents, and IFC (issued for construction). The 60% and 90% reviews are usually the highest-leverage, issues caught at 60% can still be redesigned cheaply; issues caught after IFC become RFIs or change orders.

Who should review construction documents internally?

At a minimum: a senior project engineer or VDC lead reviews drawings for coordination and field constructability, a discipline lead reviews each major discipline (structural, MEP, fire/life-safety) against the relevant code, and the project executive reviews scope and contract alignment. On complex projects, named third-party plan reviewers (independent code consultants, peer reviewers) add depth at 90% CDs.

What should a plan review checklist include?

Three layers: (1) code citations with specific section numbers (e.g., IBC 1011 stair widths, NEC 110.26 working clearances, IPC fixture counts), (2) coordination checks at discipline interfaces (structural-MEP penetrations, ceiling-grid clashes, plumbing chase routing through fire-rated walls), (3) project-specific scope items pulled from the contract documents and owner program. Generic 'check for errors' checklists don't drive findings.

How long should a plan review take?

A focused first-pass review of a medium commercial project (200–400 sheets) typically takes 20–40 hours of senior reviewer time per discipline, plus 5–10 hours of revision review per cycle. AI-assisted review compresses the first-pass time substantially. Helonic surfaces code-compliance and coordination findings across an entire drawing set in minutes per sheet, which lets the senior reviewer spend their time on judgment calls instead of triage.

What metrics indicate a plan review workflow is working?

The leading indicator is findings density at each phase, a healthy workflow finds the most issues at 60% CDs and far fewer at IFC. The lagging indicators are RFI volume during construction (fewer is better) and change-order count tied to documentation issues (fewer is better). A workflow that finds nothing at 60% but generates 200 RFIs in the first six months of construction has shifted detection too late.
