137.1 Airports & high-footfall sites

Prioritize egress and queue safety (231, 237). HVM bollard arrays must coexist with trolleys/carts. Any crash rated bollard near glazing needs height/offset checks (312, 234).

Airports mix heavy footfall, carts, and 24/7 operations. Start with egress widths and queue geometry, then set array breakpoints for trolley turn radii. At curtain-wall frontages, confirm effective height from FFL and the glazing stand-off; cross-check with height setting and frontage protection.

Keep clear-gaps consistent at doors and security lanes. Where vehicle approach is possible, model approach vectors and use perpendicular rows or shallow chicanes from array patterns to dissipate energy before frontages.

137.2 Government & embassy sites

Higher tiers, tighter standoff, stricter evidence (123, 431). HVM bollard arrays may include chicanes (321). A crash rated bollard must map to policy and witness expectations (717, 638).

Embassy compounds expect demonstrable stand-off distance and documented certificates. Align site drawings and calculations with a submission index so reviewers can trace each claim. For UAE projects, include succinct notes on SIRA coordination and witness booking via SIRA Bollards (UAE).

Use chicane/offset entries from array patterns to reduce run-up. Pre-agree witness points in the SAT procedure, and make sure the ITP shows hold points for foundations and controls.

137.3 Critical infrastructure

Service access and robust drainage (245, 334) dominate. HVM bollard layouts protect approach vectors (214). Crash rated bollard variants should allow maintenance without breaching certification (415).

Plants, data centers, and utilities require uninterrupted operations. Keep service doors navigable while eliminating straight approach vectors to critical rooms. Specify sump/relief paths per drainage strategy and equipment pits (616), then validate long-term maintenance access.

Choose a product family with variant breadth (product families/variants) so sleeve swaps and accessory upgrades don’t invalidate the as-tested configuration. Where groundwater is an issue, pair footing design with soil/groundwater guidance.

137.4 Retail/malls/fuel stations

Blend protection with legibility (316, 366). HVM bollard spacing must respect crossings (232, 237). Confirm fuel-area electrical classifications when siting a crash rated bollard panel (347).

Shoppers need obvious paths to doors and crossings; prioritize sightlines & signage and complementary finishes. Use consistent clear-gap calculations at zebra crossings and cart routes, with tactile cues where needed.

At fuel stations, confirm panel siting with hazardous-area classifications from enclosures & cabling and coordinate emergency stops and interlocks with the forecourt systems.

137.5 Hotels & mixed-use

Valet lanes demand automatic HVM bollard control logic and signage (342, 353). Choose a quiet crash rated bollard drive/enclosure to meet acoustic limits (546).

Guest experience is key: pair control logic with highly visible safety signalling and stewarded island layouts that separate pedestrians from valet flows. Automatic lanes should fail predictably and present clear states to drivers and staff.

Where rooms overlook drop-offs, specify low-noise drives and acoustic treatment (acoustic limits). Plan modes of operation for day/night and event loading.

137.6 Education & healthcare

Accessibility and emergency access first (233, 238). HVM bollard arrays must avoid creating trip hazards. Crash rated bollard heads/lighting aid wayfinding (313).

Keep kerb-free access and blue-light routes open by using removable/passive gaps where permitted, or automatic lanes with strict interlock matrices. Avoid low-contrast collars and specify tactile/contrasting heads from heads & attachments.

Outside clinics and schools, prioritize shaded waiting areas and clear sightlines (streetscape integration). Document accessible routes in the ITP so inspections check both security and accessibility.

137.7 Stadiums & events

Temporary modes and rapid reconfiguration (239, 327). HVM bollard patterns adapt to flows; crash rated bollard lines protect perimeters with stewarded gaps.

Event footprints change hourly. Use temporary/event reconfiguration with modular arrays that open wider before ingress and narrow to stewarded gaps post-event. Maintain service access for emergency vehicles with documented emergency access routes.

Protect long, straight concourse approaches by alternating patterns (e.g., offset rows) and, where needed, adding removable infills at pinch points (corners & pinch points).

137.8 Ports & marinas

Corrosion resistance, coatings, and marine chlorides (361–363). HVM bollard sockets need drainage (334). Select a crash rated bollard family with proven coastal durability.

Salt spray and tidal splash accelerate deterioration. Choose stainless grades and coatings per materials selection and coatings, and detail seals around sleeves to prevent ingress. Where sockets sit below deck, design drainage sumps and maintenance access.

Prefer product lines with published coastal references and inspect galvanic interfaces (galvanic risks). Schedule more frequent inspections in the maintenance plan.

137.9 Streets & pedestrian areas

Sightlines and rhythm matter (238, 316). HVM bollard clear gaps must serve mobility devices (232). Keep crash rated bollard finishes resilient to cleaning and stickers (366).

Public realms rely on rhythm and visibility. Keep posts aligned with furniture lines and avoid visual clutter; see aesthetics that work. Confirm clear-gap rules against mobility devices and double strollers, with small offsets at corners for turning envelopes.

Specify robust finishes and anti-graffiti topcoats from color & aesthetic finishes. If automatic lanes interface with fire routes, coordinate overrides and EFO expectations with authorities.
