What is spec vs drawing review?

Spec vs drawing review compares project specifications against construction drawings to find contradictions. Specs and drawings are often created by different teams at different times, leading to material conflicts, outdated references, and missing details that cause RFIs and rework.

What types of conflicts does the Spec vs Drawing Checker find?

Material mismatches (drawings call out one product, specs require another); installation method conflicts; outdated spec references; boilerplate errors; missing spec sections for systems shown in drawings; performance requirements that conflict with specified products; finish discrepancies.

Can I try it on my project specs?

Yes. Upload your project specifications and drawings on the website, and the AI will show you the conflicts it finds — start with a $50 check, money-back guarantee if we don't find 5+ meaningful issues. Watch the demo video to see a walkthrough first.

What are the most common spec-drawing conflicts?

The most common issues are material conflicts (VCT vs LVT flooring, TPO vs EPDM roofing), outdated boilerplate spec language that contradicts project-specific drawings, and missing spec sections for systems that appear in the drawings. These typically surface as RFIs during bidding or construction.

Why Spec-Drawing Conflicts Cost So Much

Specifications and drawings are created by different teams at different times. Conflicts between them are inevitable—but discovering them in the field is expensive.

A single material mismatch can trigger an RFI, delay procurement, and snowball into schedule delays and change orders.

Common issues that lead to costly rework:

Material conflicts: drawings show one product, specs require another
Finish discrepancies between spec sections and finish schedules
Installation method conflicts between drawings and specs
Outdated spec references that don't match current drawings
Boilerplate spec language that contradicts project-specific details
Missing spec sections for systems shown in drawings
Performance requirements that conflict with specified products

What the AI Spec vs Drawing Checker Catches

AI cross-references specifications against drawings to surface conflicts that are tedious to catch manually but expensive to fix in the field.

Material & Product Conflicts

Drawing callouts vs spec section requirements
Product substitutions that don't meet spec requirements
Finish schedule conflicts with spec sections
Hardware specifications vs door/window schedules
Membrane and waterproofing product conflicts

Installation Method Mismatches

Spec-required installation methods vs detail drawings
Fastener and anchor requirements conflicts
Joint and sealant specification mismatches
Substrate preparation conflicts
Application rate and coverage discrepancies

Performance Requirement Gaps

Fire rating conflicts between specs and drawings
Acoustic performance requirements vs assembly details
Thermal performance specs vs envelope details
Structural capacity requirements vs specified products
Warranty requirements that conflict with product selections

Outdated & Boilerplate Issues

Outdated product references in specifications
Boilerplate language that contradicts project details
Superseded code references in specs
Standard details that conflict with spec requirements
Copy-paste errors from previous projects

Missing & Incomplete Specs

Systems shown in drawings with no spec section
Spec sections that reference missing drawings
Incomplete product specifications
Missing submittal requirements
Gaps between Division sections

Code & Standard Conflicts

Spec-referenced standards vs drawing details
Code requirements in specs vs construction details
Testing and inspection requirements gaps
Certification requirements vs specified products
Accessibility requirements conflicts

Real Issues We've Caught

Actual issues found on real projects. Each one would have caused significant rework, change orders, or schedule delays.

Flooring Material ConflictHigh

What AI Found: Drawings called out 'VCT flooring per finish schedule.' Spec Section 096519 specified LVT with different installation requirements.

Impact: Prevented procurement confusion and installation rework. Would have required flooring replacement.

Roofing Membrane MismatchCritical

What AI Found: Roof details showed TPO membrane, but roofing specifications required EPDM membrane with different attachment methods.

Impact: Caught before roofing subcontract buyout. Would have caused change order and schedule delay.

Structural Steel Coating ConflictHigh

What AI Found: Structural drawings specified shop primer only, but spec section required intumescent fireproofing coating.

Impact: Prevented costly field application of fireproofing that should have been applied at fabrication shop.

Door Hardware Specification GapMedium

What AI Found: Door schedule showed electric strikes on secure doors, but hardware spec section had no electric strike requirements or power coordination.

Impact: Caught before hardware procurement. Would have caused installation delays and electrical coordination issues.

What Construction Professionals Say

GCs, architects, engineers, contractors, and developers use InspectMind AI to catch issues before they hit the field.

"InspectMind caught 47 critical issues on our cold storage project: conflicts that would have cost us millions in field rework. It paid for itself on the first review."

Aaron Bass

Director of Construction, Cold Summit Development

"We used to spend 40+ hours on plan review. Now I upload the drawings, and get back a complete issue report that catches code violations I would have missed. It's a no-brainer."

Julio

Owner, Pesco Engineering
