Inspections, audits and records

Every Thursday afternoon, Owen Hartley walked Cottonwood Place from the bottom of the east lane excavation to the top of the tower crane's mast ladder platform, with a different foreman each week and, once a month, with Lena Petrov, the worker co-chair of the site safety committee. He carried a tablet with the inspection form and took photographs of everything he flagged. Over two years he recorded more than 2,000 findings. About a third were fixed while he was standing there. Most of the rest were fixed within a day. A handful took weeks, and those were the ones that taught the most.

Inspections are how a general contractor finds hazards before they hurt someone, and records are how it proves it looked. This lesson covers both, and the audits that check whether the whole system is working.

Why inspections are required

OSHA's construction rules require inspections at several levels. Under 1926.20(b)(2), employers must provide for frequent and regular inspections of job sites, materials and equipment by competent persons. Specific standards add their own: excavations daily and after rainstorms (1926.651(k)), scaffolds before each shift and after any occurrence that could affect structural integrity (1926.451(f)(3)), personal fall arrest systems before each use (1926.502(d)(21)), cranes each shift, monthly and annually (1926.1412), and ladders periodically and after any occurrence that could damage them (1926.1053(b)(15)). Under the multi-employer policy, a controlling employer's inspection program is a large part of what OSHA examines when deciding whether it exercised reasonable care.

Layers of inspection

No single inspection can find everything. Tallgrass uses layers, from the worker checking a harness before putting it on to the external auditor looking at the whole program once a year. Each layer catches different things at a different frequency.

• Pre-use checks by workers. Harnesses and lanyards, ladders, power tools, cords and aerial lifts are checked by the person using them before each use, against a short checklist.
• Start-of-shift checks by foremen. Before the crew starts, the foreman walks the work area: guardrails, openings, access, housekeeping, the condition of the work left the day before.
• Competent person inspections. Excavations, scaffolds, cranes and other equipment that the rules require to be inspected are checked by a designated competent person at the required frequency, with a written or tagged record.
• The general contractor's site inspection. Tallgrass's weekly walk covers the whole site, every trade's work area and the shared hazards, and checks that the lower layers are happening.
• Committee inspections. Once a month, the safety coordinator walks with the worker co-chair or another worker member, who brings a worker's eye to what is happening.
• Audits. Once a year, an internal or external auditor checks the program itself: whether procedures exist, are known and are followed, and whether records are complete.

What makes an inspection useful

A good inspection looks at conditions and at how the work is being done, and talks to the people doing it. Owen's Thursday walks followed a few habits that made them useful rather than routine.

• Follow the work, not a fixed route. Go to where the high-risk work is happening this week, using the look-ahead.
• Look up, look down, look behind. Overhead loads, openings underfoot, and the area behind a worker who is about to step back.
• Ask, don't just look. Ask a worker to explain how they will do the task, what could go wrong and what they would do. The answers reveal whether training and planning are real.
• Fix on the spot where you can. A loose guardrail toe board or a cord across a walkway can be fixed in a minute. Record it anyway.
• Record specifically. 'Housekeeping poor' is useless. 'Level 4, grid C to D: drywall offcuts and banding blocking the stair tower door' can be fixed and checked.
• Rank by risk. Each finding gets a risk class so the most serious get the fastest response.

Tracking deficiencies to closure

Finding a hazard is only half the job. Every finding goes into the deficiency log with its class, location, photograph, responsible company and due date. The responsible foreman closes it by fixing the problem and sending a photograph, and Ben Nakamura or Owen verifies the fix on their next walk. Anything overdue is escalated: first to the subcontractor's project manager, then to Tallgrass's project manager, who can use the subcontract's remedies.

Owen runs a short report every Monday to see what is open and what is late.

from datetime import date
today = date(2027, 10, 18)
due_days = {"A": 0, "B": 0, "C": 3}
log = [
    ("D-1182", "A", "Brooks Electric", date(2027, 10, 18), None),
    ("D-1175", "B", "Highline Scaffold", date(2027, 10, 15), date(2027, 10, 15)),
    ("D-1170", "C", "Pinecrest Interiors", date(2027, 10, 11), None),
    ("D-1168", "C", "Lone Star Mechanical", date(2027, 10, 12), date(2027, 10, 14)),
    ("D-1160", "B", "Pinecrest Interiors", date(2027, 10, 8), None),
]
def workdays(a, b):
    n, d = 0, a
    while d < b:
        if d.weekday() < 5:
            n += 1
        d = date.fromordinal(d.toordinal() + 1)
    return n
for ref, cls, firm, found, closed in log:
    if closed:
        continue
    age = workdays(found, today)
    late = age > due_days[cls]
    print(f"{ref} class {cls} {firm:20s} open {age} working days {'OVERDUE' if late else ''}")

D-1182 class A Brooks Electric      open 0 working days 
D-1170 class C Pinecrest Interiors  open 5 working days OVERDUE
D-1160 class B Pinecrest Interiors  open 6 working days OVERDUE

The report shows two overdue items for Pinecrest, one of them a class B finding open for six working days. That pattern, rather than any single finding, is what triggered a call to Pinecrest's project manager and, eventually, the weekly reviews described in lesson 8.

Looking for patterns

Individual findings get fixed. Patterns tell you what is wrong with the system. Every month, Owen sorts the findings by type, trade, floor and class. In the first winter, a quarter of all findings were housekeeping on the upper floors, which led to the floor-by-floor cleanup schedule described in lesson 4. In the second summer, findings about missing tool tethers rose after a new drywall crew arrived, which led to a toolbox talk series and tethers issued at the gate. A deficiency log that is only used to close items wastes its most valuable information.

Audits

An audit asks a different question from an inspection. An inspection asks whether conditions on the site are safe today. An audit asks whether the safety program is designed properly and working as designed: whether procedures exist for the site's hazards, whether workers and supervisors know them, whether inspections and training happen as scheduled, and whether records are complete and accurate. Tallgrass audits each major project once a year, using a corporate safety manager from another region so the auditor is independent of the site team. The Cottonwood Place audit in its first year found strong inspection and training records but weak follow-up on near-miss reports: a third had no recorded action. Owen added a weekly review of open near misses at the coordination meeting.

Records

Records serve three purposes: they help the site manage its hazards day to day, they let the company learn from patterns over time, and they provide evidence that duties were met. Tallgrass keeps the following for every project.

• Orientation and training records for every worker on site.
• Pre-task plans, foremen's daily reports and toolbox talk sign-in sheets.
• Inspection forms, competent person inspection records and equipment inspection tags and certificates.
• The deficiency log with photographs and close-out dates.
• Permits to work.
• Committee minutes and recommendations, and the responses to them.
• The OSHA 300 log, 301 incident reports and 300A summaries, which must be kept for five years after the year they cover.
• Citations, settlement agreements, abatement certifications and correspondence with OSHA.
• Exposure monitoring results, such as noise and silica sampling, which under 29 CFR 1910.1020 must generally be kept for 30 years, and medical records for the duration of employment plus 30 years.

A record has to be honest to be useful. Tallgrass's rule is that records are made at the time, by the person who did the work, and never altered afterwards except by a dated correction. A missed inspection is recorded as missed, not filled in later. Backdated or invented records have destroyed more companies' defenses than missing ones, because they turn a gap into a lie.

Going digital

Tallgrass moved Cottonwood Place to tablet-based forms in its second month. Inspections, pre-task plans, permits and the deficiency log all went into one system, with photographs, time stamps and automatic reminders for overdue items. Foremen who had resisted at first came round when they found that a deficiency assigned to them arrived on their phone with a photograph and a location, rather than as a vague comment at the Tuesday meeting. Paper forms were kept as a backup for areas with no signal, such as the bottom of the excavation, and entered within a day.

Inspecting the inspectors

One job of the general contractor's weekly walk is to check that the lower layers are actually happening. On each walk, Owen picks three or four required inspections and checks their records against what he sees: the excavation inspection log at the top of the east lane ladder, the scaffold tags on the bays he passes, the pre-use checklist in the aerial lift's document box, a foreman's start-of-shift sheet. In the second month he found a scaffold tag dated four days earlier on a bay that had clearly been altered since, which led to the rule that only Highline Scaffold LLC may alter scaffolds and that any alteration means a new inspection and a new tag. A record that says an inspection happened, when the conditions show it could not have, is a warning sign about the whole layer.

Inspections by the owner and others

Tallgrass was not the only party inspecting Cottonwood Place. The owner's project manager walked the site monthly, the insurer's loss control consultant visited each quarter, the city's building inspectors came at each permit stage, and the engineer of record inspected the shoring, formwork and structure at set milestones. Owen treated each visit as a free second opinion. He asked each visitor to share their observations in writing and added any safety findings to the deficiency log with the same risk classes and due dates as his own. The insurer's consultant, who had seen hundreds of sites, was particularly good at spotting things the site team had stopped noticing, such as a fire extinguisher hidden behind a pallet of insulation that everyone walked past every day.
