Datum designs, certifies and delivers critical-infrastructure perimeters across Australia — kilometres on program, zero lost-time injuries.
The Perimeter Spec Pack
Pick the asset, set the threat profile, drag the line. The elevation redraws, the standards stack up, and the program lands in weeks — a pre-qualified scope you can take straight into a tender conversation.

01 · Deter
Anti-climb 358 weldmesh, palisade and tubular systems on engineered footings — dead straight over kilometres, floodlit to CPTED principles. The first layer of security is a perimeter that tells anyone watching that this site is not the soft target.
Spec a perimeter like this
02 · Detect
PIDS fibre on the line, CCTV and thermal camera poles at the spacings the detection design calls for, terminations documented and handed to your security integrator. Climb, cut or lift registers to the zone — the fence is a sensor, not just steel.

03 · Delay
The 76.2 × 12.7 mm aperture is the whole argument: too narrow for fingers, too tight for tools. Clamp bars and tamper-resistant through-bolts mean nothing unscrews from the outside — every minute of delay is a minute your response has.
Spec a perimeter like this
04 · Deny
PAS 68 / IWA 14 crash-rated sliding gates, bollard arrays and sally-port configurations, engineered to the site and certified in the handover pack. Access control coordinated with your integrator so the perimeter and the entry are one system.
Spec a perimeter like this
05 · Respond
Sterile corridors that stay sterile, gate hardware that works in the wet, lighting that leaves nowhere to stand in shadow. We build the perimeter around the response plan — and hand over as-builts your operations team can actually use.

Delivered — substation perimeter program, NSW
A commercial perimeter should run like the program says it will. This is the path.
We walk the line with your security consultant or ours — threats, zones, services in the ground, and what the tender actually needs.
System selection, elevations, footing details and a staged program — drawings your engineer can approve without a redline cycle.
AS 1725.3 compliance, SCEC-listed product classes where the zone requires them, crash-rating certificates for HVM packages.
Sealed work zones, out-of-hours switchovers, daily prestarts — the site stays live and secure while the new line goes in.
Torque records, termination schedules, certificates and as-builts in one pack. Your auditor gets answers, not a chase.
Package managers, consultants and facility teams — the reviews that matter at prequal.
“Held a 14-week substation program to the day, on a live site, without a single incident report. Our client noticed.”
“The only fencing sub who arrived at tender review with shop drawings and a PIDS integration plan already drawn.”
“Eight kilometres, three staged separations, zero LTIs. The prequal reviewer had nothing to ask.”
“Their as-built pack answered the auditor’s questions before the auditor asked them. That has never happened before.”
“Crash-rated entry certified, documented and commissioned with our access-control integrator like one team.”
“We stopped tendering fencing to three subs. Datum prices off the drawings and the number holds.”
Chainwire to AS 1725.3, 358 anti-climb weldmesh in SCEC-listed product classes where government zones require them, and PAS 68 / IWA 14 certification on crash-rated gates and bollards. Every certificate lands in the handover pack.
That is the normal case, not the exception — staged separations, sealed work zones and out-of-hours switchovers keep the existing line secure until the new one takes over. The staging plan is part of the spec pack.
Off the drawings, as a fixed lump sum against a staged program — never a retail rate card. Build a spec pack above, and the tender price follows a site walk.
Yes — PIDS fibre on the line, camera and thermal poles at design spacings, conduits and terminations documented and coordinated with your security integrator so commissioning is one visit, not three.
Zero lost-time injuries across the last 1,180+ days of delivery, CM3 prequalified, SWMS per stage. On critical-infrastructure sites, the safety file is the first thing we are asked for and the first thing we hand over.
Start the conversation
Head contractors get a priced, staged tender response. Consultants get details and specs to reference. Asset owners get a site walk and an honest read on what the perimeter actually needs.
