Checklist

Traffic Management Near Excavation is the structured process of implementing and verifying temporary controls that keep vehicles, plant, and pedestrians safely separated around dig zones. This checklist supports work zone traffic control, detour management, and flagging operations within construction sites. The scope is implementation only: verify barriers, lighting, flagger positioning, and signed detours against the approved traffic management plan—per approved project specifications and authority requirements—without redesigning public roads or permanent layouts. By focusing on practical placements, measurable tolerances, and daily documentation, the checklist helps avoid edge strikes, reversing incidents, pedestrian interface risks, and night-shift visibility failures. It also accelerates audits and approvals with photo evidence, radio-check logs, and redlined plans where adjustments are required. Use this interactive tool to tick items in real time, add comments, and export PDF/Excel reports secured by a QR code for traceable sign-offs.

Ensure safe, plan-compliant temporary traffic controls around excavation areas using measurable tolerances for barrier continuity, signage chainage, lighting levels, and flagger sight distances. The checklist drives consistent implementation without overreaching into public road redesign.
Interactive online checklist with tick, comment, and export features secured by QR code.
Boost night-shift safety and audit readiness with lux-meter readings, geo-tagged photos, radio-check logs, and approval records. The structure helps teams preempt gaps, replace missing devices quickly, and document corrections before opening works to traffic.
Improve coordination between site supervisors, flaggers, and plant operators through briefings, clear detour diagrams, and change control. Records demonstrate compliance with approved project specifications and authority requirements, supporting inspections and closeout.

Planning & Documentation

1. Confirm the latest approved traffic management plan is at the workface; verify title, revision, and date match the excavation stage; capture a photo with the plan visible and record the revision ID.
2. Verify required notifications/permits are on file per approved project specifications and authority requirements; note permit numbers, validity dates, and issuing authority; take a photo of posted permits.
3. Hold a pre-shift briefing with flaggers, plant operators, and supervisor; cover detours, hazards, and emergency access; collect signatures on toolbox-talk sheet and photo the briefing board.
4. Stake and mark the excavation influence zone per plan using tape/paint; maintain offsets within ±0.2 m from plan; attach annotated photos showing measurements and stake IDs.
5. Record weather and visibility before work; if visibility < 200 m or wind > 10 m/s, apply plan contingencies or pause flagging; attach a timestamped weather screenshot and action taken.

Signage & Communication

6. Install advance warning signs at planned chainage using a measuring wheel; placement tolerance ±5 m; photograph each sign with chainage reference or measured distance.
7. Inspect sign condition and reflectivity; ensure clean, undamaged, and night-suitable reflective sheeting; acceptance: retroreflectivity above manufacturer minimum; document with close-up photos and inspection log.
8. Post site speed limit signs per plan (e.g., 10–20 km/h) at entry points and before detours; verify sign mounting height 1.5–2.0 m using a tape measure; capture photos.
9. Issue two-way radios to all flaggers/spotters; perform a radio check and record call signs and times; acceptance: 100% devices pass; attach the radio-check log.
10. Display a simplified detour diagram at the site access and briefing board showing dates, contact number, and emergency route; photograph the display in situ.

Barriers & Protection

11. Install continuous physical barriers along the excavation edge as per plan; offset ≥ 1.0 m from crest; ensure no gaps > 0.2 m; provide measured, geo-tagged photos.
12. Erect pedestrian fencing minimum 1.2 m high with toe-board where drop > 0.6 m; post spacing ≤ 2.0 m; evidence: measurements recorded and photos along the run.
13. Install approved end treatments or taper buffers per plan; verify orientation with traffic and taper length within ±10% of plan; photograph device labels and setup.
14. Secure service and access points with lockable gates; keep closed when unattended; record lock ID and add a log entry; attach a photo of the secured gate.
15. Place trench plates for crossings; confirm plate rating exceeds expected axle load by ≥ 20%; edges pinned or ramped; evidence: plate serials, manufacturer data, and photos.

Lighting & Visibility

16. Position lighting towers to avoid driver glare; measure ≥ 50 lx on detour paths and ≥ 100 lx at flagging points at 1.0 m height using a lux meter; log readings.
17. Route power cables overhead or through cable ramps; eliminate trip hazards; use IP-rated connectors; acceptance: overhead clearance ≥ 2.5 m; attach photos.
18. Fit cones/delineators with reflective collars; spacing ≤ 5 m along tapers and exposed edges; replace damaged or contaminated devices immediately; provide photos of full runs.
19. Maintain lighting and fuel spares to cover the shift plus 25%; evidence: inventory count, storage location photo, and sign-out log for replacements.

Flagging & Detours

20. Verify flaggers hold current training and photo ID; PPE includes Class 3 high-visibility garments, hard hat, and gloves; capture ID snapshots (with permission) and expiry dates.
21. Position flaggers as per plan; confirm sight distance ≥ 80 m for 20 km/h traffic using a laser rangefinder; record measured distance and a location photo.
22. Confirm radio and hand-signal protocols; rehearse STOP/SLOW and emergency halt before opening; collect signatures on drill checklist and attach a photo.
23. Inspect vehicle detour: clear width ≥ 3.5 m, gradient ≤ 10%, curve radius ≥ 12 m, firm surface without standing water; record measurements and photographs.
24. Set pedestrian detour: width ≥ 1.2 m, ramps ≤ 1:12 at crossings, lighting present, and barrier separation from vehicles; provide measured photos.

Monitoring & Records

25. Complete start and end-of-shift inspections; document defects and rectification times; acceptance: no unresolved critical items before opening; attach signed checklists with timestamps.
26. Capture geo-tagged photos after initial setup and after any modification; store in a dated folder linked to chainage/grid; attach the folder link.
27. Redline any deviations to the plan and obtain traffic manager approval before implementation; attach the marked drawing and approval signature.
28. Verify emergency access remains unobstructed; conduct a timed drill to clear a barrier section; acceptance: response time ≤ 2 minutes; record stopwatch result.
29. Remove or reconfigure temporary controls when excavation stages change or works pause > 24 h; store devices safely; attach closeout photos and inventory reconciliation.

Why robust controls around excavations matter

Excavations create abrupt level changes, sightline interruptions, and constrained pathways that can surprise drivers and pedestrians. Without disciplined traffic controls, minor errors escalate quickly: a missing taper device draws vehicles too close to the edge, a dark zone hides a pedestrian, or an unclear detour forces last‑second maneuvers. This checklist organizes those risks into verifiable steps: barriers and fencing create physical separation; signage and radios provide predictable cues; lighting restores visibility during low‑light conditions; and flagging coordinates movement when geometry or operations change. The goal is safety through repeatable process, not improvisation. We focus strictly on implementing the approved temporary traffic plan around the excavation—no public road redesign, no permanent layouts. Success looks like continuity (no barrier gaps), visibility (measured illuminance), and clarity (consistent signals). Each item requests tangible evidence: measurements, photos, or signatures, ensuring that controls are not just placed, but verified and documented.

Prevent edge strikes and pedestrian conflicts with physical separation.
Use measured tolerances to verify positions and lighting levels.
Keep flagger actions predictable with radios and rehearsed signals.
Stay within scope: implement the approved temporary plan only.

Field methods, tolerances, and acceptance cues

Practical verification beats assumptions. Use a measuring wheel to locate advance signs within ±5 m of planned chainage. For barriers, maintain a minimum 1.0 m offset from the excavation crest and eliminate gaps over 0.2 m—photograph joints and end treatments. A lux meter confirms ≥50 lx on detours and ≥100 lx at flagging points measured at 1.0 m height; reposition light towers to reduce glare. Rangefinders help ensure flagger sight distances (e.g., ≥80 m for 20 km/h). Detours must physically accommodate the largest plant: ≥3.5 m clear width, gradients ≤10%, curves ≥12 m radius, and a firm, drained surface. Trench plates require capacity greater than the heaviest expected axle load by at least 20%; record serials and manufacturer data. Acceptance is evidence-based: geo-tagged photos, measurement logs, and sign-offs. If conditions change—wind, rain, or staging—apply contingencies specified in the plan and record any redlines with approvals before implementation.

Measure, photograph, and log—assume nothing.
Control glare; verify illuminance with a lux meter.
Check detour geometry with width, gradient, and radius.
Document device ratings and serial numbers.

Documentation, communication, and change control

Controls work only when people understand them. Start with a toolbox briefing covering detour routes, interface points, and emergency access. Post a simple diagram at the gate for delivery drivers and visitors. Radios must be issued, tested, and logged so flaggers can coordinate stops and releases. Maintain a shared folder of geo-tagged setup photos, lux readings, and daily checklists; this forms an auditable trail that supports inspections and closeout. When field constraints require adjustments, mark up the plan and obtain the traffic manager’s approval prior to changes—no ad‑hoc reconfigurations. At handover or shift end, verify critical items are resolved and remove redundant devices to prevent confusion. Throughout, cite compliance as “per approved project specifications and authority requirements,” avoiding guesswork about specific clauses. Proper records not only demonstrate due diligence; they also make repeat setups faster and more consistent across shifts and stages.

Brief, test radios, and log attendees.
Keep a photo and measurement evidence trail.
Approve and record all deviations before changes.
Close out and remove redundant devices.

FAQ

Question: What if site conditions differ from the approved traffic plan during excavation?

Do not improvise in the field. Redline the affected plan segment, describe the constraint, and seek approval from the traffic manager per approved project specifications and authority requirements. Implement temporary safe holds, document photos and measurements, then proceed only after written approval.

Question: How much lighting is required for safe detours and flagging at night?

Use a lux meter at 1.0 m height. Provide at least 50 lx along detour paths and 100 lx at flagging locations. Reposition towers to reduce glare toward drivers, secure cables, and log readings with photos. Replace lamps or add a tower if readings fall short.

Question: When should flaggers be used instead of temporary signals near excavations?

Use flaggers when geometry changes frequently, visibility is limited, or plant movements are unpredictable—typical around active digs. Ensure current training, radios, clear sight distances, and rehearsed signals. Where layouts stabilize, consider transitioning to plan-specified controls after approval and documentation.

Question: How do I verify a detour accommodates large site vehicles?

Measure clear width, gradient, and turning radius against the plan and expected vehicle dimensions. As a guide: width ≥ 3.5 m, gradient ≤ 10%, radius ≥ 12 m, with a firm, drained surface. Confirm trench plates or crossings exceed axle loads by at least 20% and document evidence.
