About this role

You will work on live civils packages where setting out accuracy, QA records and coordination with site management directly affect programme, adoption and handover.

Mainline Groundworks delivers enabling works, substructure and external infrastructure for developers, housebuilders and principal contractors. Site engineers on our packages are involved from setting out through to as-built records — not desk-based roles detached from the site.

What you will do on site

  • Setting out for earthworks, drainage, roads and external works to issued design
  • QA checks, level control and dimensional records for inspection hold points
  • Coordination with site management, foremen and subcontract gangs
  • Utilities and drainage interfaces — clashes, protection and revised lines
  • As-built surveys, red-line mark-ups and record packs for adoption
  • Client, consultant and subcontractor liaison on technical queries
  • Supporting RAMS, method statements and safe working set-ups
  • Attending progress meetings and flagging programme risk early

What we need from you

  • Previous site engineering experience on groundworks or civil engineering packages
  • Practical understanding of drainage, roads or infrastructure delivery — not building-only background
  • Competent use of setting out equipment (total station / GPS as applicable)
  • Working knowledge of AutoCAD for reading and marking drawings
  • Valid CSCS card and full UK driving licence
  • Ability to produce clear site records under programme pressure

Also useful — not essential

  • S38, S104 or S278 adoption experience on development sites
  • Residential phase handover or housebuilder plot infrastructure
  • Working with principal contractors on live, multi-trade sites
  • Utility diversion or statutory undertaker coordination
  • Degree or HNC in civil engineering (not essential if site experience is strong)

  • Collaborative site teams with clear communication and safety focus
  • Practical role with direct influence on programme and quality outcomes
