Just Won a Contract? How to Mobilise Site Labour in 10 Days

You've won the contract. The client wants boots on site inside a fortnight. This is the checklist we run with SME contractors across London and the South East every week. It assumes a project up to about £2m — fit-out, refurb, residential, small groundworks — and a workforce of roughly 4–20 people.

Before day one — a 30-minute prep

  • Confirm site address, access route, and site working hours.
  • Nail down start date and expected duration.
  • List trades required by phase and rough numbers.
  • Note ticket requirements (CSCS level, SSSTS/SMSTS, asbestos awareness, first aid, plant tickets).
  • Decide welfare, PPE, and induction arrangements.
  • Nominate the on-site point of contact and their number.

Send this as a single brief to your agency. It saves three rounds of email and gets a shortlist back within hours.

Week 1 — Contracts, admin, workforce brief

  • Day 1 — Confirm contract, appoint site manager, kick off internal handover.
  • Day 1–2 — Send workforce brief to agency: trades, numbers, start date, site address, shift pattern, ticket requirements, welfare on site.
  • Day 2 — Issue subcontractor and plant enquiries in parallel. Book welfare unit and hoarding.
  • Day 3 — Client pre-start meeting. Lock down programme critical path.
  • Day 3–4 — RAMS in draft. Induction pack in draft. Confirm CDM roles.
  • Day 4 — Agency returns worker profiles for approval. Verify tickets on CSCS Smart Check.
  • Day 5 — Insurances and warranties sent to client. Welfare delivered to site. First week's workforce confirmed.

Week 2 — Set-up, induction, first shift

  • Day 6 — Temp power and site security in place. First delivery slots booked.
  • Day 6–7 — Site set-up: hoarding, signage, welfare fit-out, waste plan.
  • Day 7 — RAMS signed off. Induction pack finalised. Toolbox talks scheduled.
  • Day 8 — Confirm workforce start day. Send site address, arrival time, PPE requirements, and induction slot to the agency.
  • Day 8–9 — First workers arrive for induction. Right to Work verified on site as a second check.
  • Day 9 — Snag walk with site manager. Confirm labour balance for week 3.
  • Day 10 — Site live. First productive shift. Debrief with agency on any gaps, adjust week 3 numbers.

Common bottlenecks and how to dodge them

  • Welfare arriving late. Book it on day 1 — lead times slip to 5–7 days in busy months.
  • RAMS not signed off in time. Draft on day 3, get client sign-off before day 8 so workers don't stand around on day 10.
  • Right to Work delays. If your agency doesn't provide RTW evidence with the worker profile, they aren't ready to deploy.
  • Under-briefed workforce. Send the site address, arrival time, parking, and induction slot the day before. First-day no-shows are usually a briefing failure, not a worker failure.
  • One-agency risk. For anything over 15 workers, use two agencies for the same trade so a shortfall from one is covered.

What to send your agency on day 1

A one-page workforce brief that includes:

  • Site address and postcode
  • Client / main contractor name (if not you)
  • Start date and expected end date
  • Trades and numbers by week
  • Shift pattern (7:30–4:30, weekends?)
  • Ticket requirements per trade
  • PPE requirements (hi-vis colour, gloves spec, safety spec glasses)
  • Welfare and parking arrangements
  • Site contact name and mobile
Answers

Frequently asked questions

For most SME contracts under £2m — fit-out, refurbishment, small groundworks, residential — yes. The bottleneck is rarely labour; it's welfare, insurances, and the client's pre-start pack. If those are queued up in parallel with recruitment, a 10-working-day mobilisation is realistic.

Two things in parallel: get the site set-up moving (welfare, hoarding, temp power, permits) and issue your workforce brief to your agency. Everything else — RAMS, inductions, first delivery — sits on top of those two.

Give the agency the full ticket profile, exact start date, site address, welfare arrangements, and PPE requirements up front. Confirm the induction slot. Send the RAMS in advance so workers can review before day one. Pay first invoice on time — it keeps supply prioritised.
