Commercial fencing, bought on a specification

Define what the fence is actually for

Deterrence, delay, demarcation, containment, screening and safety are different jobs and they produce different fences. A perimeter meant to slow a determined intruder is not the same product as one meant to stop people cutting across a car park.

Watch for: A specification written as a product rather than as a requirement. If the brief says "eight foot chain link" rather than what the fence must achieve, you will get exactly that and find out later it did not address the problem.

Survey, easements and title

Commercial parcels carry easements, rights of way, utility corridors and sometimes access agreements that a residential lot does not. A perimeter that blocks a utility easement or an access right is a legal problem regardless of how well it is built.

Watch for: Fencing across an easement without checking the wording. The utility or the benefiting party can require removal, and on a commercial perimeter that is a large number. Pull the title documents before the line is set.

Zoning, permit and — where relevant — design review

Commercial fencing frequently attracts more scrutiny than residential: frontage treatment, sight triangles at vehicle exits, screening requirements, and in some districts a design review of anything visible from the street.

Watch for: Assuming residential rules apply. Height and material allowances on a commercial or industrial parcel often differ from the residential ones, in both directions, and the frontage is usually where the restriction bites.

Contractor selection and the paperwork

Certificates of insurance naming the right parties, workers' compensation, licensing where required, and on public or larger private work a bond. References should be for comparable work, not for residential fencing.

Watch for: A certificate of insurance provided as a screenshot or by the contractor rather than by the carrier or broker. Ask for it to be issued directly, with your entity named as certificate holder and additional insured where your contract requires it. This is basic and it is skipped constantly.

Phasing and temporary perimeter

Replacing a perimeter means the site is open while it happens. Phasing keeps the property secure, and temporary fencing covers the gaps — and someone has to be responsible for it.

Watch for: No stated position on who owns security during the works. If the old fence comes down on a Friday and the new one goes up on Tuesday, decide now — in the contract — who is liable for what happens over that weekend.

Gates, access control and the interface with other trades

Vehicle gates, operators, intercoms, card readers, loop detectors and fire-service access all cross trade boundaries. The fencing contractor supplies the gate; the powered and networked side is electrical and security work.

Watch for: The gap between trades. Conduit, power supply and low-voltage pathways need to be in someone's scope explicitly. This interface is where commercial gate projects lose weeks, because everyone assumed the other party had it.

Handover, as-builts and maintenance

You should receive the sign-off, the warranty documents, the gate operator manuals and a marked-up drawing of what was actually built including any buried conduit.

Watch for: No as-built record of what is in the ground. The next contractor on site will dig, and the drawing is what stops them finding your gate power the hard way.
