Mechanical Site Manager

London | Secure Estate / Prison | Contract

Up to £335 per day (depending on experience) + staying away allowance

Our client is a well-regarded M&E specialist with a strong track record delivering complex refurbishment and new-build projects across the secure estate. They run structured delivery teams with clear reporting lines and solid on-site support, and they're now looking for an experienced Mechanical Site Manager to lead mechanical delivery on a live MEP package .

You'll take ownership of mechanical supervision on site — managing subcontract labour, driving quality and programme, and keeping everything compliant in a secure, controlled-access environment.

What you'll be doing

* Run mechanical supervision on site: labour, sequencing, access constraints, permits, and short-interval planning.

* Manage subcontract mechanical trades and specialist vendors (pipework, ductwork, plant installation, testing/commissioning support).

* Own H&S: RAMS, permits, daily briefings, toolbox talks, safe systems of work in a secure environment, and close-out of actions.

* Drive quality control: benchmarks, ITPs, inspections, snag management, and “right-first-time” installs.

* Coordinate with the wider project team on programme and interfaces (M&E coordination, builderswork, ceilings/walls, penetrations, plant risers and routes).

* Control materials and logistics, including receipt, issue and storage of client-supplied major equipment and plant.

* Keep tight records: daily diaries, progress reporting, labour returns, QA packs, as-builts and handover support.

What you'll need

* Proven experience as a Mechanical Site Manager / Supervisor delivering MEP projects, ideally within secure, live or controlled-access environments.

* Strong mechanical installation knowledge: pipework, ductwork, plant, heating/ventilation systems, testing coordination and commissioning readiness.

* SSSTS or SMSTS (SSSTS minimum).

* Relevant mechanical trade background / qualification — HNC/HND useful but not essential.

* Comfortable running subcontract labour, managing interfaces, and pushing programme without sacrificing quality.

* Able to pass the relevant security / vetting requirements for a prison environment.
