Location Codes for Construction Sites
How contractors can mark site gates, laydown areas and delivery points with exact location codes for suppliers and subcontractors.
Updated 14 October 2026 · 3 min read
A construction site is a moving address. The plot may have no street number until late in the project, access gates open and close as phases change, and the place a concrete truck needs to be on Monday may not be the same place on Friday. Suppliers who are not told precisely where to go tend to arrive at the wrong gate.
Who needs the location
On any given day, a site receives deliveries of materials, plant hire, skip lorries, inspectors, subcontractors and visitors. Each arrives from a different direction and none of them has been to the site before. The site manager can answer calls from all of them, or give them a reference that makes the calls unnecessary.
One code per purpose
Instead of a single address, use several codes, each labelled for what it is:
- Main gate for visitors and inspectors.
- Goods-in for material deliveries.
- Crane or concrete pump position for specialist vehicles.
- Muster point for safety arrangements, held alongside your own procedures.
Include the right code in each purchase order or booking confirmation. Because a code corresponds to a fixed point, a supplier's driver and the site's gatekeeper can refer to the same place on the phone without ambiguity.
Managing change
Treat codes like gate signage. When a phase moves the entrance, create a new code and mark the old one as retired in your own system. The old pin remains valid as a location, but it should not be used for deliveries. A short change log on the site's information sheet saves repeated mistakes.
Limits
A code does not carry site rules. It cannot tell a driver about height limits, required PPE, banksmen or time slots, and it does not open a gate. It also cannot define the site boundary, which belongs to the project's drawings. Keep induction and access arrangements in your usual documents.
The REST API can generate codes from latitude and longitude, which suits teams that already record surveyed points; the documentation describes the endpoints. For related situations see freight and trucking and mining, oil and remote sites.
Keeping the list current
Put the active codes on the site information board and in the supplier welcome pack, and review them at each phase meeting. A short, current list prevents far more confusion than a long list that nobody trusts.
Frequently asked questions
Do site locations change often?
Entrances and laydown areas can move as work progresses. Create a new code when the access point moves and tell suppliers which one is current.
