Estimator – Residential Extensions & Renovations
Casual — 3 days per week | Work-from-home flexibility
About the role
BPG Construction Solutions is a Brisbane-based building company specialising in residential renovations, extensions, and new builds. We're looking for a sharp, detail-driven Estimator to price and prepare quotes for our residential extension and renovation projects.
This starts as a 3-day-per-week contract / temporary position, with a genuine pathway to grow into a part-time or full-time role for the right person. You'll work closely with the builder and project management team, own the numbers on your jobs, and produce estimates that are accurate, complete, and ready to put in front of clients.
What you'll do
Price residential extension and renovation jobs from plans, specifications, and site information
Use the Rawlinsons Australian Construction Handbook as your primary cost reference for pricing and rate build-ups
Input and manage all costs through our Wunderbuild platform — this is where estimates, cost plans, and job pricing live
Prepare transparent, professional quotes with a full schedule of inclusions and exclusions so there's no ambiguity for the client
Set and manage Provisional Sums (PS) and Prime Cost (PC) items accurately, with sound allowances
Liaise with suppliers and subcontractors to confirm rates and quotes
Work with the builder and project managers to make sure estimates reflect the real scope and buildability of each job
What you'll need




Proven estimating experience in residential construction — specifically extensions and renovations
Strong working knowledge of the Rawlinsons guide and the ability to build up accurate rates from it
A solid understanding of structural engineering — you can read and interpret engineered drawings (footings, bored piers, slabs, steel, bracing) and accurately price the work they call for
Solid understanding of Provisional Sums and PC items — how to set them, allow for them, and communicate them clearly
Confidence reading residential plans and specifications
A methodical approach to inclusions and exclusions — you understand how much a well-defined scope protects both the builder and the client
Comfortable working with construction software; Wunderbuild experience is a plus, but we'll get you up to speed if you're a quick learner
Reliable, self‐managing, and able to work independently from home for part of the week
Current driver's licence
What we offer
3 days per week to start, with flexibility to work from home
Performance bonuses paid when jobs are delivered at or above target margin — accurate pricing is rewarded
A clear path to a part‐time or full‐time role as the workload and fit develop
Direct involvement in a busy, hands‐on residential builder where your estimates drive real jobs
A supportive team and straightforward, no‐nonsense working culture
