Mechanical & Welding Freelance Estimator Needed
Budget: $250 – $750 AUD
Freelance Estimator / Engineer – Mechanical & Welding Works Tender Brief
Project Overview
PSM Welding is seeking a freelance estimator / engineer to assist with pricing a lump sum (LS) tender for a project involving mechanical, pipe support, and welding works within a live industrial environment.
This brief is intentionally client-agnostic and excludes any identifying project or client details.
Scope of Works to Be Priced
The freelancer will be required to review issued drawings, schedules, and quantities and develop a complete LS pricing model for the following mechanical and welding-related works only:
1. Mechanical & Pipe Support Works
Fabrication, supply, galvanising, and installation of mechanical pipe supports
Structural steel supports for process pipework (columns, beams, base plates, stiffeners, brackets)
Hold-down bolts, cast-in items, and connection plates associated with pipe supports
Alignment and installation of supports (pipe supply excluded unless noted)
2. Welding Works
Workshop and site welding associated with mechanical supports and pipe interfaces
Butt welds, fillet welds, and connection welds in accordance with AS/NZS standards
Allowance for qualified welders, consumables, and standard weld testing where specified
Compliance with project welding procedures and ITP requirements
3. Minor Structural Steel (Mechanical Only)
Mechanical support frames and secondary steel required to support pipework and equipment
No primary building steel or architectural steel included
Items Explicitly Excluded from Pricing
The estimator must not include costs for the following unless expressly instructed:
Electrical works (HV/LV, isolations, terminations, commissioning)
Civil works unrelated to mechanical supports
Building works, architectural finishes, or non-mechanical structures
Traffic control, site access management, or security
Inductions, permits, escorts, or access delays
Standby time due to access or permit constraints
Rock excavation, contaminated material, or abnormal ground conditions
Design development beyond issued drawings
Commercial & Pricing Requirements
Contract type: Lump Sum (LS)
Pricing to be assumption-based, not risk-loaded
Access, ingress/egress, and site control assumed to be managed by others
Allow for normal working hours only
No allowance for productivity loss due to access or permit delays
Deliverables Required
The freelancer is expected to provide:
Detailed quantity take-offs for mechanical supports and welding scope
A clear pricing breakdown (materials, labour, fabrication, installation)
Identification of pricing assumptions and exclusions
Flagging of scope gaps, ambiguities, or missing information
A final LS price recommendation suitable for tender submission
Ideal Candidate
Proven experience in mechanical and welding estimating
Strong understanding of pipe support systems and structural steel for mechanical services
Familiar with Australian Standards (AS/NZS 1554, AS/NZS 5131, AS4100)
Comfortable working with incomplete or concept-level design packages
Able to work to tight timeframes and provide clear commercial input
Timeframe
Immediate engagement
Short turnaround to meet tender submission deadlines
