  • Oversee compliance with the Contract Administration Manual and Security of Payment obligations
  • Manage and verify the Monthly Progress Payment process
  • Act as the Principal’s Representative when authorised

  • A collaborative, detail‑driven approach aligned to high‑performance team cultures
