851.1 BOQ structure

Split prelims, civils, HVM bollard hardware, crash rated bollard controls, testing, O&M (611, 631, 733).

Organise the BOQ to follow how work is actually delivered: (a) prelims and site set-up; (b) civils and foundations (see 330 Foundations & Loads); (c) hardware lines for fixed and automatic bollards; (d) controls, cabling and enclosures; (e) testing, handover and training. This makes like-for-like comparison easier and reduces scope gaps between civil and MEP packages.

Keep product systems separate from foundations and controls. Hardware lines should state the tested system and rating, while foundations reference the selected foundation class and any drainage (334 Drainage). Controls/cabling belong under Section 520–529 with dedicated lines for power sources and PLC/Controller I/O.

Include explicit assumptions/exclusions and note provisional sums for utility clashes (241–246). Cross-reference to commissioning pages 631–638 for testing and to documentation pages 733 and 938 for handover packs so that each stage has cost visibility.

851.2 Item descriptions

Reference Page IDs and rating dependencies (421, 411–416). Descriptions prevent silent substitutions.

Write each line so it is unambiguous. For hardware, include the crash rating string, tested orientation, and any rating-critical dependencies (see 421 and 410 group). Name the product family/variant and finish, and state the required accessories (caps, beacons, sleeves).

For civils, call up foundation type, depth class, drainage provisions and any known utility constraints; reference 246 Ducting & Pathways and 335 Underground Utilities. For controls, specify enclosure NEMA/IP rating, cable sizes, terminations, and I/O points (521–529). Clear text here blocks “like-for-like” downgrades.

851.3 Measurement rules

Define per-unit vs linear vs lump-sum for arrays, ducts, drainage (321–326, 246, 245).

Agree the unit of measurement for each work type: bollards and sleeves measured “per unit”; array grade beams “per metre”; draw pits and sumps “each”; ducts “per metre including bends and draw wire”; reinstatement “per m²”. For arrays (321–326), clarify how corners and mixed-type transitions are counted to avoid under-measurement in complex frontages.

For drainage (245) and duct banks (246), define what is included in the rate (excavation, bedding, backfill, mandrel test, gaskets). For automatic systems, state whether cable terminations, ferruling and panel programming are included in the line rate or measured separately under commissioning (631–637). These rules keep valuations fair across the programme.

851.4 Provisional quantities

Use for utilities clashes and dewatering (243, 614). Protect HVM bollard budget swings.

Carry provisional sums/quantities for high-variance items: unexpected utilities proof and diversions (241–243), groundwater management (614) and drainage tie-ins (334). Link each provisional to a trigger (e.g., CAT/GPR results, trial pits) with a priced daywork schedule so overruns are controlled, not disputed.

Record assumptions in an assumptions register and tie them to drawing notes (931) and survey deliverables (248). This protects the core HVM hardware budget from being raided by unforeseen civils.

851.5 Dayworks & minor civils

List plant/labour for reactive tasks. Keeps crash rated bollard progress fluid.

Add a concise dayworks schedule covering labour grades, small tools and typical plant (mini-excavator, trench box, pumps) for reactive works—think service avoidance, spoil handling, or reinstatement around bollard sockets. Reference 617 Utility Conflicts and 628 Backfilling & Compaction so that field teams have priced options when surprises emerge.

Keep lists to sensible maximums (≤7 items per subcategory) and ensure rates include mobilisation, access constraints, and disposal. This reduces claims and keeps the installation sequence on track.

851.6 Testing & commissioning lines

FAT/SAT, evidence packs, witnesses (715, 638, 716). Make quality measurable.

Include explicit lines for pre-commission checks (631), power-on health (632), loop/sensor proving (633), interlock verification (634), obstruction/intrusion (635), performance/duty (636), EFO/failure modes (637), and SAT/witness procedure (638). Separate rates motivate completion of each test with evidence, not just attendance.

Where applicable, add Factory Acceptance Test readiness (715) and an evidence capture standard (716) line covering photos, logs and evidence packs. Name the required witnesses and approval hold points in the description so attendance and sign-off are budgeted.

851.7 Spares & tools lines

Include critical spares and test tools (854, 529). Ensures HVM bollard uptime.

Create a small critical spares kit per lane—seals, hoses, sensors, coils, beacon lenses—and maintenance consumables. Add commissioning and diagnostic tools under 529 (loop simulator, pressure test kit, firmware loader) so field recovery is fast and independent of third parties.

Reference warranty/service terms in 854 Warranty & Spares Policy and align stock levels with the 734 Preventive Maintenance Plan.

851.8 O&M & training lines

Manuals, training sessions, records (733, 737). Costs visible up-front.

Add separate lines for 733 O&M manuals, training sessions with signed attendance sheets (737), and as-built records (731–732). Describe deliverables: language, format (PDF/editable), count of sessions, duration, and competency outcomes. This turns handover from an afterthought into a priced, schedulable work package.

If UAE approvals apply, include time for SIRA coordination inside the training/hand-over window and link any client acceptance forms to the SAT step (638) for a clean release.

851.9 BOQ–drawings tie-in

Cross-reference 931 sheets. Traceability secures crash rated bollard scope.

Every BOQ line should point to a drawing note, schedule or detail: bollard tags to GA schedules; socket depths to foundation typicals (933); ducts and pits to trench details (934); signage and markings to schedules (935). Maintain a drawing-to-BOQ cross-index so changes are traceable during addenda.

Use 931 CAD/BIM Standards title blocks and ensure “as-tested configuration” details are carried through. For submission quality, align the final 938 Submission-Pack Guidance with the BOQ so reviewers can price-check quickly.
