Scope (fixed bollards only)

This page covers fixed (passive) crash-rated bollards—not automatic.
If you’re new to terminology, start with
Basics of HVM Bollards →
Bollard definition and
Bollards by function.

Dubai/SIRA note: SIRA documentation mentions PAS 68:2013 (crash test)
and PAS 69:2013 (selection/installation). For SIRA-led jobs, align wording with those pages
and your own SIRA content:
SIRA Crash Ratings,
SIRA Installation — What to Expect,
SIRA Foundations & Installation,
SIRA Documentation & Handover.

Standards landscape (what to state on submittals)

• Current international baseline: ISO 22343-1 (Vehicle security barriers — performance).
• Withdrawn internationally but still cited locally: PAS 68 (crash) and PAS 69 (selection/installation). IWA 14-1 is also withdrawn/superseded.
• For Dubai projects referencing SIRA, use PAS 68 wording for the crash statement and PAS 69 language for selection/installation.

  How to read ratings.

Fixed vs automatic bollards — certification differences

Fixed bollards (this page): may be accepted by certified engineering calculations when permitted by the authority/spec; many products also have full-scale tests. The certification/engineering package always covers the bollard + foundation configuration (depth, plan, reinforcement, spacing). See
Foundation & installation dependencies.

Automatic bollards: certified as a system in the raised position (actuator + controls + safety + foundation cassette). Submittals include safety measures and interlocks:
Automatic HVM Bollard Controls and
Safety & interlocks.

What “K4” means (use US + metric)

Legacy DoS K4 ≈ stopping 15,000 lb (≈ 6,800 kg) at
30 mph (≈ 48 km/h) within a specified penetration.

Modern equivalence on submittals:
ASTM F2656 M30 (≈ K4): 6,800 kg (≈ 15,000 lb) @ 48 km/h (≈ 30 mph)
with penetration class P1/P2/P3 (P1 ≤ 1.0 m). For SIRA-led jobs, use PAS 68 phrasing for the tested case.
Background: Bollard crash testing and
Standards & terminology.

Why K4 bollards are the most requested bollard

1. Shopping-mall approach speeds are low. Geometry and calming keep approach speeds near
   30 mph / 48 km/h —
   see Approach run-up distance and
   Terrain & calming effects.
2. Most façades don’t face highways. Urban streets limit run-up —
   see Perimeter & approach paths.
3. Secure-by-Design sites. Street furniture and planters create barrier-by-design, reducing K8/K12 demand —
   see Planning for HVM projects and
   Security Bollards Design & Build — Scope.

Shallow-mount vs deep-mount (when & why)

Why shallow is requested more (even though system price is higher):

• Faster, cleaner installation with lower install cost/time. Live malls want minimal hoarding and noise.
• Avoid services. Retrofits sit over dense utilities; shallow cassettes avoid deep trenching near services.

Depth language to standardize:

• Deep-mount: > 500 mm and < 750 mm embedment (target ~500–600 mm).
  See Foundations & loads.
• Shallow-mount: < 200 mm embedment (certified cassette/array). Many systems require a
  minimum array count and fixed spacing—check the certificate. See
  Arrays & spacing and
  Shallow foundations.

HVM Bollards Installation and the SIRA guide

Engineering tasks & documentation

• Vehicle Dynamics Assessment (VDA): establish approach speeds/angles → choose rating & stand-off.
  Start at VDA hub and use the
  VDA worksheet.
• Dynamic Load Assessment: verify forces into slabs/footings. A quick sense check:
  Foundation moment quick estimator.
• Foundation verification: certification is for the bollard system (incl. foundation).
  Your footing depth/plan/rebar/concrete strength must match the tested/engineered configuration —
  see Impact loads & foundations,
  Foundation types,
  Design checks,
  and CAD/BIM Foundation typicals.
• Follow approved drawings & rebar schedules: installers must build per
  rebar cages & anchors.
• Authorized installer: use a manufacturer-authorized installer to preserve certification and warranty —
  see Warranty & spares policy.
• Warranty: specify warranty for the bollard system (steel core + any cover)
  and a separate warranty for installation workmanship.
  Closeout aids: Handover pack index & checklists.

ATG K4 fixed bollards (QUA — authorized distributor & installer)

• ATG SP30 — fixed, K4/M30 family (deep-mount band: > 500 mm and < 750 mm; confirm exact).
• ATG SP400 SM 48 — shallow-mount (< 200 mm), K4/M30 family; cassette/array with defined minimum count & spacing.

See SIRA section: ATG HVM Bollards. For budgeting, see
Bollard cost UAE.

Buyer checklist (copy into RFP/BOQ)

• Rating line: “K4 (ASTM F2656 M30) fixed bollards — P-level required (P1 ≤ 1.0 m preferred).”
• Vehicle & speed (US + metric): 15,000 lb (≈ 6,800 kg) @ 30 mph (≈ 48 km/h).
• Foundation strategy: Deep-mount > 500 mm and < 750 mm (target ~500–600 mm)
  or Shallow-mount < 200 mm cassette/array (state minimum array count & spacing).
• Spacing: clear gap typically ≤ 1,200 mm (confirm certificate) —
  Spacing rules.
• Materials/finish: S355J2H (EN 10219), HDG ISO 1461, optional powder-coat (ISO 12944).
• Submittals: Crash certificate or engineering calculation package for the exact configuration,
  GA/foundation drawings, rebar schedules, install tolerances; authorized installer credentials; warranty (system + installation).
  See Documentation & certificates.

Advice for owners & consultants (maintenance / emergency access)

Use K4 fixed bollards to permanently block areas that should not be crossed. For
maintenance or emergency lanes, fixed K4 posts require cranes/rigging to remove—unlike decorative/parking posts; where regular vehicle access is needed, specify
automatic bollards for those lanes and keep fixed K4 where permanent blocking is required.
See Emergency service access.
