JOB OVERVIEW

About Rockleigh Services

Rockleigh Services is an Australian-owned earthmoving and civil construction contractor based in South Australia. We work with private clients, builders, developers and commercial businesses on projects ranging from small earthworks through to subdivisions and civil infrastructure.

Our work includes land subdivisions; bulk earthworks and site preparation; roads, access roads and driveways; stormwater drainage, pits, culverts and headwalls; underground water and electrical service trenches; retaining walls and gabion walls; civil concrete; building and shed pads; demolition; and general earthmoving. Our fleet includes excavators, bulldozers, graders, skid steers, rollers and specialised equipment.

About the position

We are seeking an experienced Estimator to provide reliable and detail-oriented pricing, quotes and proposals to support the ongoing growth and success of Rockleigh Services. The role involves interpreting drawings, completing accurate take-offs and bills of quantities (BOQs), preparing cost breakdowns, coordinating with suppliers and our internal team to prepare and submit professional quotations and tenders.
This is a technical estimating position, not simply data entry. The successful applicant must understand how civil and earthmoving works are undertaken, recognise gaps in documentation, and take responsibility for the accuracy of their work. We encourage you to ask questions rather than guess.

Duties & responsibilities
Estimating and quantity take-offs
• Review civil engineering drawings, specifications, construction plans and tender documents.
• Prepare detailed quantity take-offs and BOQs for earthworks, drainage, underground services, roadworks and associated civil works.
• Calculate excavation, cut and fill, trenching, spoil disposal, bedding, backfill, aggregate, concrete, pipe and pit quantities.
• Identify machinery, labour, materials, haulage and subcontractor requirements, including construction sequencing and anticipated productivity.
• Apply company-approved rates and assumptions to build detailed cost estimates for management review.
Tendering and quotations
• Break projects into logical work activities and produce clear, itemised quotation breakdowns.
• Identify inclusions, exclusions, allowances, assumptions, variations and potential project risks.
• Identify missing or conflicting information and prepare requests for information (RFIs).
• Update estimates as drawings and scopes change; assist with variation pricing and tender submissions.
• Prepare materials lists and pricing enquiries for Australian suppliers and subcontractors.
• Compare supplier and subcontractor quotations, specifications and scope differences.
• Maintain organised estimating files, cost libraries, calculations and tender records.
• Track outstanding pricing, deadlines and documentation and give clear progress updates to management.

Qualifications & Experience
Required
• Demonstrated estimating experience in civil construction, earthworks or infrastructure.
• Ability to interpret civil engineering drawings and produce accurate, auditable take-offs and BOQs.
• Understanding of excavation, drainage, underground services, construction materials and earthmoving methods.
• Strong Microsoft Excel skills and sound numerical accuracy.
• Good written and spoken English, reliable communication and ability to work independently.
Preferred
• Experience estimating Australian civil construction projects and familiarity with Australian terminology and metric units.
• Understanding of machinery productivity, earthmoving costs, hire rates and construction programs.
• Previous experience supporting an Australian contractor remotely.
• Engineering degree or equivalent background

Working arrangements
• Remote position based in the Philippines, working with our South Australian team.
• Full-time, long-term position as an independent contractor.
• Fixed hours: Monday to Friday 9:30am-5:30pm (ACST/ACDT) – 7:00am to 3:00pm / 7:30am to 3:30pm Philippines Time depending on daylight savings
• Must have a professional set up: reliable, fast computer and internet, plus a good quality webcam an microphone for video calls and screen sharing.

How to apply
We read every application – please follow these steps:
• Start your message with the word ‘Rockleigh’ so we know you read this ad to the end.
• A short explanation of the civil works you have personally estimated, including project types.
• In three to four sentences tell us about a recent project you priced / quoted. Include details about your process, any tools or software you used, and what you produced.
• Include a copy of your resume / CV
