Site compound set-up
A site compound provides welfare, storage, and often office space so the project can operate safely and legally from day one. Compound set-up is a classic enabling deliverable: fencing, cabin bases, temporary services, and logistics layout.
This page covers compound construction and set-up within site preparation. Enabling-works-explained frames the wider package; fencing and access pages cover perimeter and haul routes that serve the compound.
A compound in the wrong place blocks future dig or forces double handling. Place it with the full programme in mind, not only week one convenience.
Welfare is both a legal expectation and a productivity tool. Undersized toilets and missing drying rooms show up as absenteeism and poor morale on wet UK sites.
Compounds make welfare and storage real so productive work can proceed. Location, base strength, and gate layout either support the dig or fight it for the whole programme. Set compounds with the end-state plot layout in mind.

When sequence matters
When welfare and storage are required before main works; when enabling includes compound bases; when secure material storage is needed; or when cabin and toilet provision must meet welfare expectations for the workforce size.
It also appears when a poorly sited compound must be moved mid-project — expensive and avoidable.
Size drying and toilet provision for peak headcount including subcontract peaks, not the enabling skeleton crew.
When principal contractor welfare standards or CDM expectations require cabins before meaningful workforce arrival; when secure COSHH and fuel storage must be separated from cabin doors.
Typical sequence
Step 1: Agree location and size
What this step delivers: Phasing conflicts checked.
Step 2: Form bases and secure perimeter
What this step delivers: Hardstanding and fencing ready.
Step 3: Install welfare and services
What this step delivers: Cabins operable.
Step 4: Maintain and demobilise
What this step delivers: Compound cleared when done.

Works typically include forming hardstanding bases, installing fencing and gates, setting cabins and welfare units, arranging temporary power and water where required, and organising parking and delivery space.
Duration drives whether temporary stone bases are enough or a more durable make-up is justified. Fuel and COSHH storage need compliant arrangements.
Mainline delivers compound set-up as part of enabling packages. Temporary service connections follow supplier rules.
Separate pedestrian routes from wagon loops at the compound gate. Mixed pedestrian-vehicle conflict at the cabin door is a repeated incident pattern.
Keep delivery drop zones clear of cabin fire exits. Convenience stacking becomes a safety defect.
Plan power and water early with suppliers. Temporary connections that arrive a week late leave an empty compound theatre and a workforce without welfare.
Agree compound location against dig phases, deliveries, and neighbour constraints. Size welfare for peak workforce, not the first three people on site.
Confirm who pays for welfare consumables and cleaning. Small omissions create friction.
Programme risks and hold points
- Welfare and storage needed from day one
- Enabling includes compound
- Secure storage for materials
- Temporary services required
- Compound location vs dig phasing
Pre-start and handover checklist
- Compound layout plan
- Welfare unit schedule
- Base and fencing specification
- Temporary power / water plan
- Demobilisation responsibility
Keeping trades coordinated
Install a usable compound before peak mobilisation, maintain it, and clear it at the end of the package as required.
Demobilise compounds cleanly so plot digs are not fighting abandoned hardstanding without a plan.
Where time and cost usually escalate
Relocation mid-job, weak bases that rut under deliveries, and undersized welfare drive cost. See enabling Insights. Rate intent: /groundworks-costs.
Moving a compound mid-project to free a plot footprint can cost as much as the original set-up. Site it with the end-state layout in view.
Generator fuel and temporary electrics add running cost — meter and manage them.
Security lighting, CCTV, and alarm provisions — where required — belong in the compound budget. An unlocked cabin farm invites losses that dwarf a camera kit.
Where this sequence is commonly used
- Housing site starts
- Commercial enabling packages
- Constrained plots needing compact welfare layouts
Frequently asked questions
Who provides the cabins?
Often hired by the principal contractor; groundworks may form bases and connect as scoped.
Can the compound sit on future plot footprints?
Only if relocation is planned and priced. Otherwise it blocks later works.
Is compound set-up always in enabling?
Usually yes, but write it explicitly when packages are split.
How early should the compound go in?
Before meaningful workforce mobilisation — typically in the first enabling days.
What information should we send for a quote?
Latest drawings, relevant surveys, access constraints, programme dates, and any known consent or contamination notes. Clearer packs produce clearer prices.
