Field tool, not a formal evaluation: Select a structure type, rate each condition item Good / Fair / Poor / Critical, and add notes. This organizes a visual condition assessment in the field — it does not substitute for a licensed structural engineer's formal inspection, which governs actual safety determinations.
A structured field checklist for organizing a visual condition assessment of a residential house, bridge, multi-story building, or retaining wall. Rate each condition item Good/Fair/Poor/Critical, add notes, and get an instant overall condition score plus a flagged list of anything rated Poor or Critical — helping you document findings consistently before, during, or after a walkthrough.
Pick a structure type to load its category-grouped checklist (for example, a house breaks into Foundation, Framing, Roof, and Exterior Walls; a bridge into Deck, Superstructure, Substructure, and Bearings/Joints). Rate each item Good, Fair, Poor, or Critical and optionally add a note describing what you observed. The tool computes a running average condition score (on a 4.0 scale), a category-by-category breakdown, and a prominent list of any items flagged Poor or Critical so nothing gets buried in a long list.
A house, a bridge, a multi-story building, and a retaining wall fail in different ways and are inspected against different reference practices. Bridge inspections in the U.S. broadly follow the FHWA Bridge Inspector's Reference Manual categories (deck, superstructure, substructure, bearings), while building and residential condition assessments draw on general structural condition-assessment practice (in the spirit of ASTM E2018 property condition assessments and ASCE guidance). This tool mirrors that structure so the checklist categories match what a field inspector would actually walk through for each structure type.
The overall score averages every rated item on a 4-point scale (Good=4, Fair=3, Poor=2, Critical=1). A score is only as good as the items you've rated — leave items unrated if you could not observe them rather than guessing. Any single item rated "Critical" — regardless of the overall average — should be treated as requiring prompt attention from a qualified structural engineer, since a good average score can still mask one serious localized defect (e.g., scour at a bridge pier, or a cracked column in a building frame).
No. This is an educational and organizational field tool to help structure a visual condition assessment and keep notes consistent. It does not perform load calculations, code compliance checks, or engineering judgment. Any condition rated Poor or Critical, or any structure with safety concerns, should be evaluated by a qualified, licensed structural engineer before making occupancy, use, or repair decisions.
In this tool, "Poor" indicates a clearly deteriorated condition that should be scheduled for repair or further evaluation soon, while "Critical" indicates a condition that appears to pose an immediate or near-term safety concern (e.g., active structural cracking, exposed and heavily corroded reinforcement, undermined foundations) and warrants prompt engineering attention.
This tool is designed to organize field observations and is a useful starting point, but formal reports — such as those following ASTM E2018 for property condition assessments, or state DOT bridge inspection reporting requirements — have specific documentation, photography, and reporting standards. Use this checklist as a field aid, not as a replacement for the formal report format your jurisdiction or client requires.
Each structure type has distinct failure modes and inspection conventions. Bridges are inspected by deck/superstructure/substructure/bearings per FHWA practice; buildings add an envelope and life-safety systems interface category; retaining walls focus heavily on drainage and backfill since most retaining wall failures trace back to water. Matching categories to real inspection practice makes the checklist more useful than a generic one-size-fits-all list.
