Location:  South Australia
Rate:$70-$85 per hour + superannuation
Hours: 40 hours per week
Contract: Initial 3-4 months, with potential for extension
Start: Immediate
 
The Opportunity
We are seeking an experienced Contract Administrator to join a major defence construction project in South Australia.
 
Working with a leading Tier 1/2 builder on a significant defence production and demonstration facility, you will join an established commercial team, working closely with the Commercial Manager and two other Contract Administrators.

This is a hands-on, site-based role suited to a commercially minded Contract Administrator who enjoys working through subcontractor and client variations, managing contractual documentation and maintaining strong relationships with key project stakeholders.
 
The initial contract is expected to run for three to four months, with potential for extension.
 
Key Responsibilities
  • Administer and assess subcontractor variations, claims and contractual changes.
  • Prepare, review and manage client variations, ensuring appropriate documentation and approvals are obtained.
  • Liaise directly with subcontractors and client representatives to resolve commercial and contractual matters.
  • Maintain accurate contractual records, correspondence and project documentation through Aconex.
  • Support the Commercial Manager with day-to-day commercial administration and reporting.
  • Monitor contractual obligations and assist with the effective management of project costs and variations.
  • Work collaboratively with the wider project team to ensure commercial matters are managed efficiently and in line with project requirements.
 
About You
  • Proven experience as a Contract Administrator within commercial construction or major infrastructure projects.
  • Strong experience managing subcontractor and client variations.
  • Confident communicating with clients, subcontractors and internal project stakeholders.
  • Proficiency with Aconex and construction document management systems.
  • A hands-on approach, with the ability to manage contractual matters in detail rather than operating solely at a strategic or commercial management level.
  • Strong organisational, negotiation and problem-solving skills.
  • Previous Tier 1 construction and/or defence project experience will be highly regarded.
 
What's on Offer?
  • $70-$85 per hour + superannuation.
  • 40-hour working week.
  • Initial 3-4 month contract with potential for extension.
  • Immediate start on a significant defence construction project.
  • Site-based role within an established commercial team.
