Systematic Drawing Review
Upload a PDF drawing package. Plumb reviews every sheet across 14 categories of common design, documentation, fabrication, and engineering-related issues, then returns the findings in files your team already knows how to use.

What Plumb Creates
Marked-Up PDF
Your original drawing package with findings clearly identified where they occur.
- Numbered findings on the drawings
- Severity-coded comments
- Sheet-specific references
- PE-Review-Required items clearly identified
- Summary and finding details included with the package
Excel Findings Log
Every finding organized into a file your team can sort, filter, assign, and track.
- One finding per row
- Sheet reference
- Severity
- Finding description
- Recommended action
- Sortable and filterable output
Both files contain the same findings, presented for different purposes — the PDF shows each issue in context on the drawing; the Excel log lets your team organize and track it. The online viewer shows the same findings sheet by sheet, and lets you flag or remove one.

Plumb is not a replacement for your designers, detailers, checkers, or engineers. It gives your team another systematic review of the complete package before release.
Coverage
Depends on reviewer, workload, and available time
Every sheet receives the applicable systematic review checks
First-Pass Checks
Reviewed manually by your team
Plumb flags missing, conflicting, incomplete, or unclear information
Findings
Redlines, comments, or internal notes
Findings organized by sheet and severity
Timing
Competes with active project workload
Additional review pass completed before release
Professional Judgment
Your professionals make the decisions
Your professionals still make the decisions
Your team stays in control. Plumb gives them another set of findings to work from.
Plumb Does Not Replace Your QA Process. It Makes Your QA Process Harder to Beat.
Choose the Review Your Drawing Package Needs
Not every package needs the same level of review. Plumb offers three review tiers based on where the drawings are in the process and what your team needs checked.
Tier 1
Buildability Review
Systematic review for common drawing, documentation, coordination, and fabrication issues.
Best for
Routine drawing review before release to fabrication.
Tier 2
Submittal Readiness Review
Includes Tier 1 plus engineering readiness and submittal completeness against the applicable jurisdictional profile.
Best for
Packages moving toward engineering review or formal submittal.
Plumb does not determine or certify code compliance.
Tier 3
Specification Correspondence Review
Includes Tier 1 plus systematic comparison against the project specification you supply.
Best for
Specification-driven projects where the drawing package needs to be checked against project requirements.
A documentation check against the specification you supply — not a determination of contract compliance.
14 Review Categories on Every Sheet.
The review is built around the kinds of issues experienced reviewers look for with a red pen, applied systematically across the complete drawing package.
Dimensions
Are parts fully dimensioned? Do dimension chains close? Are required tolerances provided?
Welds & Joints
Are weld size, type, length, finish, and joint requirements clearly defined?
Materials & Finishes
Are material grade, thickness, alloy, coatings, colors, and finish requirements complete and consistent?
Cross-Sheet Consistency
Do general notes, details, schedules, plans, and elevations agree with one another?
Connections
Are bolt types, grades, hole patterns, edge distances, fasteners, and connection requirements clearly documented?
Fabrication & Assembly
Are subassemblies, fabrication relationships, bill of materials, and sequence requirements clear enough to build from?
Shipping & Field Installation
Are splice locations, handling requirements, installation conditions, anchors, and field interfaces coordinated?
Scope & Professional Review
Are by-others items and scope boundaries clear? Are conditions requiring engineering judgment identified for licensed professional review?
Plumb also checks document control, drawing clarity, referenced standards, bill of materials information, fabrication sequence, and other trade-specific criteria.
Plumb Flags. Your Professionals Decide.
Plumb reviews drawing and documentation packages for conditions that deserve attention.
It does not stamp drawings, make engineering decisions, certify structural adequacy, or determine code compliance.
When a potential issue can be identified from the documents, Plumb flags it. When resolving that issue requires engineering judgment, the finding is marked [PE] PE-Review-Required for review by the appropriate licensed professional.
That boundary is intentional.
