A site engineer on a four-storey residential job is posted to a town four hours from home. He checks the bar bending schedule against the shuttering, signs the pour card for each slab and chases the RMC plant for the next transit mixer. The client's RA bill is delayed, so the site imprest stops. His diesel and bus claims sit unpaid for two months. Once the fourth-floor slab is struck and cured, he joins a rival. The owner blames the market. The engineer says nobody phoned.
Contractors lose people on the rhythm of the job: mobilisation, excavation, plinth, slab cycles, finishing, snagging and handover. Exits bunch at the plinth lull and again at snagging. Each trade has its own reasons.
Site engineers and supervisors
- Remote postings with no rotation and no home visit after every second slab.
- Imprest and diesel claims held until the client clears the RA bill.
- Blame for rework after late drawing revisions or a changed finishing schedule.
- No ladder from junior engineer to planning engineer to project manager.
- Pay tied to certified bills instead of the engineer's own measurement book.
Civil contractors and residential contractors carry this problem most because of long payment cycles.
Foremen, bar benders, masons and operators
The skilled trades move on a few signals. Is the mestri honest about the day's payment? Are helmets, harnesses and boots issued, or only promised? Is lodging at the labour camp clean, with water and a place to cook? A mason hears about a better site from another gang. The next Monday, his whole group may be gone. Operators of excavators, batching plants and transit mixers leave when maintenance is poor, because they are blamed for breakdowns.
Accounts, store and quantity staff
A storekeeper reconciles cement, steel and aggregates against the daily consumption sheet. A quantity surveyor prepares the running account bill and measurement book. They are pressed when stock differences appear or the client disputes a measurement. They leave when they are asked to adjust figures to match a promise.
A way to read each exit
- 1
Call within a week
A retired site agent can call even after the person joins another gang. Ask about the last pour, the last pay week and the last toolbox talk.
- 2
Ask about the last site
Where was the camp, who was the mestri, how many days lay between the RA bill and imprest, and what gear was missing at scaffold height?
- 3
Sort into five groups
Posting distance, pay weeks, safety and camp, growth route, behaviour of a site boss.
- 4
Count by project
Four exits from one tower job point at the project manager or the client's payment cycle, not the labour market.

Road, bridge and MEP specialists
Road crews work around the paver, the roller and the hot mix plant. Their shifts follow the weather and the bituminous laying window. Bridge crews work with pile rigs, formwork and post-tensioning, where one error can stop the programme. MEP crews run conduits, cable trays, chillers and ducting, and their work follows the civil teams. Road contractors lose operators when night laying is unpaid or under-recognised. Bridge teams lose experienced pile foremen to rival projects that offer a fixed monthly retainer.
MEP supervisors leave when drawings arrive late, snag lists never end and the client holds back retention money. Electricians wait on cable tray clearances. Plumbers wait on sleeves cast in the slab. Everyone blames the last trade in.
Mind the paper that follows a worker around: gate pass, induction record, helmet issue slip and muster roll. A bar bender fined for a gate pass he never received will remember it. Where gear issue and muster entries are signed by the foreman, the owner has proof and the worker keeps his dignity.
Give the engineer a language for the work as well. Teach the junior to read a bar bending schedule against the pour card, to record curing days, to log RMC truck timings and to prepare the measurement entries for the running bill. A junior engineer who is trained in these routines feels like a professional, not an errand runner, and is less likely to leave after the first slab. Pair each new engineer with a senior foreman for the first month so the shuttering, scaffolding and plumb checks become familiar.
Start with the last project
Pull the muster roll of your last tower or road job. Mark every name that left before handover. Note the pay week, camp and gear issue for each, then pick the cheapest fix. If you would like a posting policy or leaver review shaped to your sites, outline your projects through requirements.
