We are currently recruiting for an experienced Mechanical QA/QC Engineer to join the project delivery team on a large-scale, fast-track Data Centre project in London.

The successful candidate will be responsible for ensuring that all mechanical installations are delivered in accordance with approved drawings, specifications, technical submittals, project quality requirements and applicable standards.

This is a hands-on, site-based role requiring close coordination with the Mechanical Project Manager, Construction Managers, subcontractors, QA/QC team and Commissioning team.

The role will focus on maintaining a proactive, right-first-time approach to quality, ensuring installations are inspected progressively throughout construction and that quality issues are identified and resolved before they impact commissioning or handover.

Key Responsibilities

  • Implement and maintain project Mechanical QA/QC procedures and quality requirements.
  • Review mechanical drawings, specifications, approved technical submittals, manufacturers' requirements and coordinated BIM information.
  • Prepare, review and manage Inspection & Test Plans (ITPs), inspection check sheets and quality records.
  • Carry out regular site inspections and monitor subcontractor workmanship.
  • Ensure installations comply with approved construction information and project standards.
  • Inspect mechanical systems including:
  • CHW and glycol systems
  • Pipework, valves, strainers and associated equipment
  • Pumps and pressurisation systems
  • CRAH / CRAC units
  • AHUs and ventilation systems
  • Ductwork
  • Drainage and condensate systems
  • Mechanical supports and secondary steel
  • Insulation and identification
  • BMS mechanical interfaces, sensors and controls
  • Mechanical penetrations and associated firestopping
  • Ensure equipment is installed in accordance with manufacturers' requirements and approved details.
  • Coordinate and witness required mechanical inspections and testing.
  • Witness and record pressure testing, flushing, cleaning, chemical treatment, water quality testing and system integrity testing.
  • Ensure inspections and test records are completed before works are covered, insulated or progressed.
  • Raise and manage NCRs, quality observations and defects, ensuring corrective actions are completed and formally closed.
  • Drive progressive snagging and de-snagging of mechanical installations.
  • Identify recurring quality issues and work with subcontractors to prevent repeat defects.
  • Maintain accurate QA/QC trackers covering inspections, testing, NCRs, snags and outstanding documentation.
  • Ensure redline drawings and as-built information are progressively maintained.
  • Carry out system and area walkdowns with the project team, client, consultant and commissioning representatives.
  • Coordinate closely with the Commissioning team to ensure mechanical systems are construction complete and commissioning-ready.
  • Verify QA/QC prerequisites prior to L2/L3 commissioning, Functional Performance Testing (FPT) and Integrated Systems Testing (IST).
  • Ensure outstanding quality issues are identified early and do not impact commissioning milestones.
  • Support the compilation and review of test packs, commissioning records, O&M documentation, certificates and final handover information.
  • Monitor the protection and preservation of completed mechanical installations through to handover.
  • Produce regular quality reports covering outstanding inspections, defects, NCRs, documentation and programme risks.

This is an excellent opportunity to join a major Data Centre / Mission Critical project in London within an experienced project delivery team.
