Overview
Cross-discipline consistency analysis for multi-chapter construction and infrastructure specifications. Upload a project manual or individual division specs and the agent will systematically cross-reference requirements across disciplines — HVAC, Electrical, Structural, Architectural, Fire Protection, and MEP — to find contradictions, orphaned cross-references, and outdated standard citations. Every finding includes exact clause references and quoted text so practitioners can act on it without re-reading the full spec.
Manual specification cross-referencing on a 500-page project manual can take a spec coordinator 3-5 days. The most costly contradictions — voltage mismatches between HVAC and Electrical, fire rating inconsistencies between Fire Protection and Architectural, material grade conflicts between Structural and Architectural — are often caught only during construction, when they become change orders averaging $10K-$500K each. This skill catches them at the spec review stage.
Getting Started
Upload your project specification (PDF or text) to the workspace, then activate the Specification Consistency Check skill. The agent will parse the document structure, identify CSI MasterFormat divisions, and ask which discipline pairs you want to cross-check. You can focus on specific pairs (e.g., HVAC vs. Electrical) or run a full cross-discipline analysis.
Example Conversation
Below is an example of a cross-discipline consistency check on a commercial building project specification.
You: I’ve uploaded the project manual for the Riverside Office Tower — about 320 pages covering Divisions 01 through 28. Check for contradictions between all MEP disciplines and Architectural.
Agent: I’ve parsed the project manual and identified 14 CSI divisions. Let me map each to its discipline area and build a cross-reference index.
Parsed structure:
Division Title Discipline 01 General Requirements General 03 Concrete Structural 05 Metals Structural 07 Thermal and Moisture Protection Architectural 08 Openings Architectural 09 Finishes Architectural 21 Fire Suppression Fire Protection 22 Plumbing MEP — Plumbing 23 HVAC MEP — Mechanical 26 Electrical MEP — Electrical 27 Communications MEP — Low Voltage 28 Electronic Safety and Security MEP — Low Voltage / Fire Protection I found 47 internal cross-references. I’ll now systematically analyze the following discipline pairs: HVAC↔Electrical, HVAC↔Architectural, Plumbing↔Architectural, Fire Protection↔Architectural, Fire Protection↔MEP, and Electrical↔Low Voltage.
You: Go ahead, run the full analysis.
Agent: Analysis complete. I found 11 findings across 4 discipline pairs: 3 Critical, 5 Warning, 3 Info.
Here are the critical findings:
[CRITICAL] — HVAC/Electrical voltage mismatch for AHU-1
Section 23 73 00 (Air Handling Units), Paragraph 2.1.A:
“Air Handling Unit AHU-1: 480V, 3-phase, 60 Hz. Motor: 25 HP.”
Section 26 24 16 (Panelboards), Paragraph 2.2.C, Panel Schedule MDP-M:
“Circuit 4 — AHU-1: 208V, 3-phase, 40A”
Conflict: AHU-1 is specified as 480V in the HVAC spec but the electrical panel schedule allocates a 208V circuit. A 480V motor connected to a 208V circuit will not operate and could be damaged.
Suggested resolution: Confirm with the MEP engineer whether AHU-1 is 480V (requiring a 480V panel) or 208V (requiring a different motor). This must be resolved before equipment procurement.
[CRITICAL] — Fire rating inconsistency for corridor walls
Section 09 21 16 (Gypsum Board Assemblies), Paragraph 2.3.B:
“Corridor partitions: UL Design No. V438, 1-hour fire-rated assembly”
Section 21 05 00 (Common Work Results for Fire Suppression), Paragraph 1.5.A:
“All corridors serving as part of the means of egress shall have 2-hour fire-rated enclosures per IBC Section 1020.1”
Conflict: Architectural specifies 1-hour corridor walls (UL V438) but Fire Protection requires 2-hour enclosures per IBC 1020.1. The code section cited applies to exit access corridors in buildings requiring 2-hour construction — if this building type requires 2-hour corridors, the architectural assembly must be upgraded.
Suggested resolution: Verify the building’s construction type and required corridor rating per IBC Table 1020.1. Issue an RFI to the architect.
I also flagged 3 outdated standard references — ASTM C150 cited without the combined /C150M designation, ACI 530 referenced instead of TMS 402, and ASHRAE 90.1-2016 cited when the project contract requires 2022 edition compliance.
Full report written to
output/spec-consistency-report.md. Want me to generate RFIs for the critical findings?You: Yes, generate RFIs for all three critical findings.
Agent: I’ve generated three RFIs with spec references, quoted text, and specific clarification requests:
output/rfis/rfi-001.md— HVAC/Electrical voltage mismatch for AHU-1output/rfis/rfi-002.md— Fire rating inconsistency for corridor wallsoutput/rfis/rfi-003.md— Structural steel grade conflict (A992 vs A36)Each RFI cites both spec sections, quotes the contradicting text, and requests the specific decision needed from the design team.

Findings by Discipline Pair
HVAC (Division 23) ↔ Electrical (Division 26) — 4 findings
[CRITICAL] Voltage mismatch for AHU-1
Section 23 73 00, Paragraph 2.1.A:
“Air Handling Unit AHU-1: 480V, 3-phase, 60 Hz. Motor: 25 HP.”
Section 26 24 16, Paragraph 2.2.C, Panel Schedule MDP-M:
“Circuit 4 — AHU-1: 208V, 3-phase, 40A”
Conflict: AHU-1 requires 480V per HVAC spec; Electrical panel allocates 208V. Equipment will not operate on incorrect voltage.
Suggested resolution: Confirm equipment voltage with MEP engineer. Update either HVAC equipment schedule or electrical panel schedule.
Standards Reference Validation
| # | Standard Cited | Issue | Current Status |
|---|---|---|---|
| 1 | ASTM C150 (no combined designation) | Should be ASTM C150/C150M | Combined inch-pound/SI designation required since 2019 |
| 2 | ACI 530 | Superseded by TMS 402 | ACI transferred masonry standards to The Masonry Society |
| 3 | ASHRAE 90.1-2016 | Outdated for this project | Project contract requires ASHRAE 90.1-2022 compliance |
Built-in Validation
The skill uses the agent’s document reading capabilities combined with four domain reference files to perform systematic validation. No custom extension tools are required — the validation is driven by the skill workflow and reference data.
Reference Files Used
| Reference | What It Provides | How It’s Used |
|---|---|---|
| CSI Discipline Mapping | Maps all 49 CSI MasterFormat divisions to discipline areas | Determines which sections belong to which discipline for cross-checking |
| Cross-Discipline Conflict Patterns | 8 categories of common contradictions with specific section numbers to check | Guides the agent on where to look and what conflict types to expect |
| Standards Watchlist | Known issues with commonly cited construction standards (ASTM, ANSI, ASHRAE, NFPA, IBC, ACI, AISC, AWS) | Flags withdrawn, superseded, or incorrectly cited standard versions |
| RFI Template | Standard construction RFI format | Generates properly formatted RFIs from validated findings |
Conflict Categories Checked
| Category | What It Validates | Typical Severity |
|---|---|---|
| Voltage/power mismatches | HVAC equipment power requirements vs. Electrical panel/circuit allocations | Critical |
| Material conflicts | Different ASTM/material specs for the same structural members | Critical |
| Fire rating inconsistencies | Fire protection ratings vs. architectural assembly specs | Critical |
| Dimensional/clearance conflicts | Equipment clearance requirements vs. architectural space allocations | Warning |
| Performance requirement contradictions | Load ratings, capacities, flow rates across divisions | Warning |
| Submittal requirement conflicts | Division 01 general requirements vs. individual section specs | Warning |
| Scope boundary conflicts | Work items claimed by multiple divisions or not claimed at all | Warning |
| Environmental/operating condition conflicts | Temperature, humidity, seismic ratings across systems | Warning |
Getting Started
- Create a project using the Infrastructure Specifications workspace template
- Upload your specification — a full project manual PDF or individual division PDFs
- Activate the skill by asking the agent to check for cross-discipline contradictions
- Select discipline pairs to cross-check, or let the agent check all pairs
- Review findings and generate RFIs for any critical or warning-level contradictions
Prerequisites
- A multi-discipline construction specification in PDF or text format
- Specs should follow CSI MasterFormat division numbering (Division 01-49)
- For best results, upload the complete project manual rather than isolated sections — cross-discipline checking requires seeing both sides of a potential conflict
