About Us

Excel is a well-established civil construction company operating across Sydney. We deliver large-scale projects with a strong focus on safety, quality, and getting the job done right.

The Role

We’re looking for an experienced, hands-on Office Manager who thrives in a busy construction workplace and knows how to keep things moving. This is a varied role at the centre of the business, working closely with management and supporting our office, employees and site teams across HR, recruitment, training, compliance, plant and general operations.

If you’ve worked in construction, you’ll know the drill – priorities change, things move quickly and attention to detail matters. We’re looking for someone who can stay organised, take ownership and make sure nothing falls through the cracks.

What You’ll Be Doing

- Oversee the day-to-day running of the office and reception
- Coordinate employee onboarding, offboarding, inductions, medicals and employment records
- Manage training requirements, bookings, licences, qualifications and competency registers
- Coordinate recruitment, including SEEK advertising, shortlisting, phone screening and interviews
- Maintain employee calendars, including probation, anniversaries and other key dates
- Assist management with HR administration and employee matters
- Manage insurance claims from lodgement through to repair and close-out
- Maintain company social media, website content and employment advertising
- Update capability statements, project profiles and employee CVs for client submissions
- Coordinate plant onboarding, risk assessments, site inductions and client compliance platforms




- Assist with NHVR requirements, including driver hours, mass data, fatigue, maintenance and accreditation records
- Maintain company registers, systems and records to ensure information remains current and accurate
- Work closely with management to support the day-to-day needs of the business

About You

You’ll ideally have experience in construction, civil, plant hire, transport or a similar fast-paced industry and be comfortable dealing with everyone from site crews and drivers through to clients and senior management.

- Highly organised and able to juggle multiple tasks
- Confident communicator who can deal with all types of people
- Proactive with a “get it done” attitude
- Experience in admin (construction industry highly regarded)
- Comfortable learning and working across multiple systems and client platforms
- Experienced in HR, training or compliance administration – highly regarded
- Familiar with civil construction, plant hire or NHVR requirements – advantageous
