PunchFlo is an AI-powered construction submittal review platform that automates spec compliance checking for PE firms and civil engineering teams. It reads project specifications and submittals, compares them line by line, and flags mismatches — so engineers can focus on professional judgment instead of manual cross-referencing across hundreds of pages.

How does AI submittal review work?

AI submittal review works by automatically comparing submitted construction documents against project specifications. Users upload a project spec and submittal (such as a concrete mix design or material certification), and PunchFlo's AI identifies the relevant spec sections, extracts every testable requirement, and cross-references them against the submittal data. Each requirement is scored as Pass, Fail, or Needs Attention with cited clause references including exact spec language, clause numbers, and required values.

Is PunchFlo accurate enough for PE-stamped approvals?

PunchFlo is a review assistant, not a replacement for professional engineering judgment. It automates the repetitive compliance-checking step so the reviewing engineer can make faster, better-informed decisions. The final approval always stays with the PE. PunchFlo's AI is designed to minimize false positives — when in doubt, it flags the item for human review rather than marking it compliant.

What types of construction specs does PunchFlo support?

PunchFlo supports CSI MasterFormat specifications across all divisions including concrete (ACI 301, ACI 318), structural steel (AISC), mechanical, electrical, plumbing, and earthwork. It also handles ASTM standards, DOT specifications, municipal project specs, federal agency requirements, and private-sector specs. Multi-section specs with cross-references between divisions are processed automatically.

How long does a submittal review take?

A typical AI-powered submittal review completes in 2 to 5 minutes, depending on document length and complexity. By comparison, manual submittal review typically requires 4 to 8 hours per submittal. Teams using PunchFlo report cutting overall submittal turnaround from 5 weeks to under 2 weeks.

What file formats does PunchFlo accept?

PunchFlo accepts PDF files for both specifications and submittals. It automatically extracts text, tables, and structured data from documents including mix designs, test reports, material certifications, and shop drawings with embedded text.

Does PunchFlo work with DOT and government project specs?

Yes — PunchFlo is built to handle DOT specifications, municipal project specs, and federal agency requirements. It parses multi-hundred-page spec books and cross-references submittals against the correct sections, special provisions, and supplemental specifications automatically.

How is PunchFlo different from manual submittal review?

Manual submittal review requires an engineer to open a spec PDF, locate the relevant sections, and compare every requirement against the submittal data — often across hundreds of pages. PunchFlo automates this entire process: its AI identifies relevant spec sections, extracts each testable requirement, and checks the submittal against every one. Compliant items are cleared automatically, while non-compliant items are flagged with the exact spec clause and required value so engineers know exactly what to focus on.

Can I ask questions about my project specs?

Yes — PunchFlo includes an AI chat feature for asking natural language questions about uploaded specifications. For example, you can ask 'What are the concrete strength requirements for the foundation?' and receive an answer with exact clause references. You can also ask follow-up questions about specific submittal review findings.
