In brief
- A crew allocation plan ties each trade to a date, a work face and a named supervisor, so an experienced contractor can show where every person stands on a given day.
- Contracts that pay on labour rates push bidders to win the job on headcount, and the shortfall appears later as idle crews or missing trades.
- Clients and supervisors can test allocation experience before award by asking for the previous project's crew plan and walking that site against its dates.

A bid can promise plenty of workers and still leave a Gabiley project short. Crew allocation experience gaps in Gabiley show up when a contractor can list trades but cannot say how many people work each face on each day. The labour exists, the plan does not, so one trade crowds the site while another waits on access.
What does weak crew allocation look like on site?
Weak allocation shows as people and tasks that never meet: a face with no crew, a crew with no face. Ask a contractor for its allocation table and a common answer is a total headcount. A table that works names the activity, the work face, the trade, the number of workers, the start and finish dates, and who supervises them. When one of those columns is empty, the bid is a wish, not a plan.
The mechanism is simple. Blockwork needs scaffolding and mortar mixed before the masons arrive. If the allocation plan ignores those dependencies, the first trade to start sets the pace for everyone behind it, and the delay compounds towards the end of the build, when plaster, tiles and services compete for the same rooms.
Ask for the contractor's allocation plan for a recent job, then visit that site and compare the plan with what happened. Ask the relevant local office directly whether it holds any records for the plots you are comparing, without assuming what, if anything, is available. Confirm any rule of thumb about gang sizes and output against your project's specification or engineer, because it varies with the work face.
How do unbalanced labour resources reach Gabiley sites?
The mechanism starts at tender. When a job is priced mainly on labour rates, a low bidder wins by promising a large gang at a low rate, then cannot sustain it. Ask how many of those workers have joined from another site and when that site finishes. If the answer is vague, the crew will move, and your programme will move with it.
The distortion is hardest to see in the middle of the job. Plasterers arrive while electricians are still chasing walls. Masons wait because block delivery was not sequenced against the crew. Each trade is present, so progress looks busy, but the critical path stalls. A supervisor who tracks only headcount on site records that as progress.
Read the contract to see what it allows you to ask for: monthly look-ahead programmes, crew histograms, or weekly records signed by the site supervisor. Do not assume a claim exists because the document is silent. Where the contract is silent, raise it at the pre-start meeting and record the agreed format in the minutes before work begins.
How do you check crew allocation experience before you award?
Test the bidder's own records rather than its answers. Request the allocation plan and the daily site records from one comparable completed project, then ask for the name of the supervisor who signed them. Contact that supervisor through the client and ask which trades arrived late and how the contractor responded at the time.
The second check is at the site visit. Walk the project with the proposed site supervisor and ask where each trade will stand next week, then ask what will be on the critical path that week. A supervisor with allocation experience answers with faces and dates. A supervisor without it repeats the programme.
Ask two previous clients what the labour curve looked like in the last third of the job, when trades crowd each other. If they only discuss materials, the contractor has not been tested on allocation.
What to do next
Before you sign, request one allocation plan and one set of signed daily records from a comparable completed project, plus the name of the supervisor who kept them. Ask the relevant local office what, if anything, it holds on those records before you rely on them. Then walk that finished project and compare the plan with what you see. Award only when the contractor can answer where each trade stands on a date you choose.
Frequently asked questions
Can I check a Gabiley contractor's crew allocation before I sign?
Ask for the allocation plan and signed daily site records from one comparable completed project, plus the supervisor's name, then contact that client and compare the plan against the finished building.
Does a large proposed gang mean the bid is strong?
No. A large gang without faces, dates and a named supervisor is only a headcount. Ask where each trade stands next week and what sits on the critical path.
What should the contract say about crew changes?
Ask your contract to state how the contractor reports a change in crew size and who approves a revised look-ahead programme. Check what your contract allows before you rely on it.
