Typical timeline, gates, dependencies, and long-lead items.
Build permits into the critical path. This timeline shows when to apply, book witnesses, and stage evidence for HVM bollard foundations, controls, and SAT. Cross-link your ITP (714), MS/RAMS (721–722), and Evidence Standards (716) so each inspection passes first time. We flag common delays, variation impacts (718), and the sign-off sequence that feeds the closeout pack (739, 736, 919). For UAE authority context, see SIRA Bollards (UAE). For broader orientation, jump up to this section and the chapter hub. Link installation pages only if helpful: What to Expect and Installation Guide.
Important: This is a general guide. For live projects we develop a tailored
Method Statement & Risk Assessment (MS/RA) and align with authority approvals (e.g., SIRA) where in scope.
134.1 Permit types you may need
Expect PTW, excavation, traffic management, dewatering, and electrical isolation. Sequence them to protect HVM bollard works (611–616) and ensure any crash rated bollard foundation checks are lawful (331–333). Reference authority notes (133) in your plan.
Start by confirming site rules for Permits to Work (PTW), excavation/shoring, and temporary traffic plans. In parallel, log utilities clearances from Utility Search Methods (241) and agree signage layouts via Safety Signalling (353). For automatic systems, capture electrical isolation and BMS tie-ins where inspections apply.
| Aspect | What matters | Where to verify |
|---|---|---|
| Performance | Tested system (bollard + footing) | How to read crash ratings |
| Operations | Duty cycles, fail-state, safety | Installation Guide |
134.2 Typical sequence and lead times
Apply early: utilities search (241) → traffic plan (357) → excavation/dewatering (613–614) → concrete/inspection (621–627) → commissioning/SAT booking (631–638). Build float for HVM bollard witness steps and crash rated bollard evidence reviews (431, 938).
As a rule of thumb, freeze drawings and submittals before booking hold points in the Inspection & Test Plan (ITP). Reserve lead time for road permits and for dewatering approvals if groundwater is high (see Dewatering & Groundwater, 614). Commissioning slots for automatic HVM bollards can be scarce—pre-book SAT calendars early.
134.3 Booking inspections & witnesses
Lock hold points in the ITP (714) and pre-book SAT (638). Provide array/spacing sheets (232) for HVM bollard checks and certificate extracts (431) for any crash rated bollard verification.
Share a concise “reader sequence” with inspectors so they can validate the installation quickly: spacing/clear-gaps → foundation depth class → controls/safety → performance evidence. Attach the right excerpts from Documentation & Certificates (431), and show set-out stakes or gridlines from Setting-Out & Benchmarks (612). For witness steps, align times with traffic management windows.
134.4 What to prepare for each visit
Marked drawings, set-out logs (612), photos (716), and acceptance criteria. For HVM bollard arrays, carry gap gauges (232). For a crash rated bollard, bring dependency checklist (421).
Create a single inspection pack per visit: approved drawings, BOQ excerpt, FDS pages for logic thresholds, the rating-critical dependencies list (421), and the relevant ITP line. Add a simple checklist (acceptance bands, required photos, and any Authority submittals references) to reduce on-site decisions.
134.5 Evidence capture on site
Standardize angles, distances, and levels (626), file to 716. HVM bollard results link to SAT forms (638). Crash rated bollard records attach to submission index (938).
Use the Evidence Capture Standards (716): consistent photo angles, measuring tapes in frame, and level readings adjacent to each bollard. Log readings in templates from Downloads (912–919), then cross-reference filenames per File Index & Naming Rules (911). Link evidence to each ITP hold/witness point.
134.6 Common delays & how to avoid
Late utilities proofs (243), missing drainage tests (334), and unclear signage plans (353). Use 912–919 templates and pre-brief reviewers (717) for both HVM bollard and crash rated bollard milestones.
Mitigation tips: confirm utility responses are in hand before excavation (243); pressure-test drainage pits from Drainage for HVM/Crash-Rated Bollards (334); attach a simple traffic diagram referencing Safety Signalling (353). Use the Authority Submittals (717) page to pre-brief reviewers on what will be shown during inspections.
134.7 Rework/variation impacts
Changes ripple through spacing, foundations, and controls (445, 718). Re-verify HVM bollard clear gaps (232); re-confirm crash rated bollard certificate applicability (415).
Any variation should trigger an update to the Change Log (718) and a re-check of Clear-Gap Calculations (322) or Spacing rules (232). If the model or foundation class deviates from the original certificate family, confirm applicability via Product families/variants (415) before proceeding.
134.8 Sign-off criteria
Close ITP lines with measurements/photos (714, 716). HVM bollard SAT must meet cycle/logic thresholds (636). Crash rated bollard sign-off needs certificate mapping and dependency proof (431, 421).
Define acceptance bands in the ITP and evidence pack: alignment tolerances from Datum & Alignment Checks (626), duty/cycle times from Performance & Duty Tests (636), and safety states from Fail-safe/secure states (355). Attach the certificate mapping sheet and the rating-critical dependencies (421).
134.9 Final certificate milestones
Collect completion, SAT, and authority letters (638, 739). Package HVM bollard evidence and the crash rated bollard certificate set into the final pack (938).
Before retention release, assemble the Snagging & Handover (639) items and file them under the Handover Pack Index (736). Ensure the Submission-Pack Guidance (938) index is complete, and that letters, SAT sheets, and as-builts are mirrored in the Closeout Checklist & Retention (739).

134 Permit & Inspection Timeline — FAQ
How long does permitting usually take for HVM bollards?
It varies by authority and scope, but typical flows need 2–6 weeks for utilities searches and traffic plans, 1–3 weeks for excavation/dewatering approvals, and 1–2 weeks to book SAT. Build 10–20 working days of “authority float” into your programme to absorb review cycles.
Which inspections are normally “hold” or “witness” points?
Common hold/witness points include excavation depth & shoring checks, rebar cage and embedment verification, pour and vibration checks, datum/alignment measurements, and commissioning tests (loops, interlocks, performance, EFO, SAT). Your ITP should list each with evidence required.
What evidence convinces reviewers fastest?
Consistent photos (with scale), alignment/level readings, spacing gauges in frame, and direct excerpts from certificates showing model, foundation class, and limits. Use the Evidence Capture Standards and the Submission-Pack index so reviewers can trace each claim to a source.
When should we re-apply or re-book inspections?
Re-book if a variation affects clear gaps, foundation depth/class, model family, or control logic that changes acceptance bands. Update the Change Log, refresh the ITP, and notify the authority with a short cover note linking the change to new evidence.
