Senior Estimator – Height Safety & Access Systems

Wetherill Park, Sydney NSW

Full-time

$150,000–$210,000 + superannuation, based on experience and demonstrated capability

Make a genuine impact in a specialist construction business

Technical Safety Pty Ltd is seeking an accomplished Senior Estimator to lead complex estimating, tendering and pre‑construction activities across our height‑safety, roof‑access and fall‑protection projects.

This is a senior, client‑facing position for an estimator with excellent commercial judgement, advanced construction drawing interpretation skills and the ability to take complete ownership of tenders from initial review through to submission, negotiation and project handover.

You will work directly with the Director and collaborate closely with our Project Coordinator, Junior Estimator, project teams, installers, suppliers, engineers, builders and external consultants.

This is not a junior estimating or purely drafting position. The successful candidate will be trusted to influence tender strategy, technical solutions, pricing decisions and the continued development of our estimating systems.

About Technical Safety

Technical Safety is a specialist provider of height‑safety, roof‑access, fall‑protection and façade‑access solutions for commercial buildings and construction projects.

Our work includes anchor systems, static lines, horizontal lifelines, ladders, stairs, guardrails, walkways, platforms, roof hatches, skylight‑protection systems, rope‑access provisions and other specialist access solutions.

We work with builders, developers, property groups, facility managers, strata organisations, councils and consultants to deliver practical, compliant and commercially competitive systems.

Key responsibilities

Estimating and tender management

- Take ownership of the complete tender process, from opportunity review and initial scope assessment through to final submission, clarification, negotiation and handover.
- Review architectural, structural, roof, façade, services and engineering drawings, specifications, schedules, tender addenda, consultant reports and subcontractor scope documents.
- Identify incomplete information, documentation conflicts, design risks, access limitations and scope gaps before pricing.
- Complete accurate quantity take-offs, system measurements, bills of quantities and material schedules.
- Develop detailed first‑principles estimates covering labour, materials, fabrication, engineering, freight, plant, access equipment, cranes, EWPs, scaffolding, supervision, testing, certification, preliminaries, staging and project‑specific requirements.
- Obtain, review and compare quotations from suppliers, manufacturers, engineers and subcontractors.
- Prepare comprehensive quotations and tender submissions containing clearly defined inclusions, exclusions, assumptions, qualifications, alternatives, lead times and proposed delivery methodology.
- Review tender conditions and subcontract requirements, including design responsibility, warranties, retentions, securities, liquidated damages, program obligations, access constraints and other commercial risks.
- Prepare and manage RFIs, tender clarifications and scope queries.
- Develop compliant alternative solutions and value‑engineering proposals without compromising safety, quality or design intent.
- Participate in tender interviews, scope reviews, commercial negotiations and post‑tender clarification meetings.
- Maintain an accurate tender register, submission calendar, pricing database, supplier information and historical project cost records.
- Assist the Director with bid strategy, margin review, commercial risk assessment, workload forecasting and go/no‑go decisions.
- Review tender outcomes and contribute to win/loss analysis and continuous pricing improvement.

Technical scoping and design coordination





- Interpret complex architectural and construction plans to determine safe roof‑access, fall‑protection and façade‑maintenance requirements.
- Understand roof layouts, fall hazards, access routes, structural substrates, maintenance zones, installation constraints and interaction with other building elements.
- Produce or coordinate professional concept layouts, plan mark‑ups, system schematics and tender drawings using AutoCAD and Bluebeam Revu.
- Select suitable systems and components based on the intended application, substrate, site conditions, manufacturer requirements and relevant compliance obligations.
- Coordinate design information with architects, builders, façade consultants, structural engineers, hydraulic consultants, mechanical contractors and other project stakeholders.
- Prepare clear engineering briefs and coordinate with suitably qualified engineers when certified designs, structural calculations or design verification are required.
- Ensure tendered solutions consider installation methodology, waterproofing interfaces, structural limitations, construction sequencing, future inspections, maintenance and safe system use.
- Apply a sound working knowledge of current Australian Standards, the National Construction Code, WHS requirements and manufacturer instructions relevant to height safety and access systems.
- Provide technical input to and quality review of tender returnables, ITPs, SWMS, O&M; manuals, compliance packs and installation documentation in collaboration with the Project Coordinator.
- Complete structured post‑award handovers so project teams clearly understand the accepted scope, pricing basis, exclusions, risks and client commitments.

Client and stakeholder management

- Communicate confidently and professionally with builders, architects, consultants, property managers, facility managers, strata representatives and suppliers.
- Lead client meetings, tender interviews, scope workshops, design discussions and site inspections.
- Present and explain technical solutions clearly in person, over Microsoft Teams and through formal written correspondence.
- Build trusted, long‑term client relationships while protecting the company’s commercial position.
- Respond to technical and commercial questions accurately and within required tender deadlines.
- Manage difficult scope discussions, competing interpretations and negotiations professionally.
- Maintain exceptional standards of written communication, documentation and follow‑up.

Leadership and process improvement

- Review take‑offs, quotations, layouts and tender documents prepared by the Junior Estimator.
- Provide practical guidance, technical support and mentoring to developing team members.
- Work closely with the Project Coordinator to ensure tender documentation and submission requirements are complete.
- Establish quality‑control checks to reduce estimating errors, omissions and inconsistencies.
- Improve estimating templates, quotation formats, product libraries, labour allowances, standard inclusions and exclusions, and pricing procedures.
- Help develop scalable systems that improve tender accuracy, turnaround time and reporting.
- Demonstrate excellent integrity when handling confidential pricing, supplier, client and company information.
