About me

On the work & what I bring.

I'm Shubhangi, a Senior Estimator with eight years across Victoria's rail, civil and utilities programs. I build estimates that decision-makers trust, communicate with stakeholders from procurement to project sponsors, and bring discipline to the messy commercial reality of capital delivery.

RPV review

I help teams turn scope, drawings and risk into defensible numbers, the kind that survive contingency reviews and sponsor scrutiny without unraveling at delivery.

My background is unusual: a double degree in Civil Engineering and Business from Swinburne, followed by an internship at Yarra Trams Infrastructure, a graduate role at Comdain, and eight years at Metro Trains Melbourne supporting RPV, LXRP and Franchise programs through tender and operational estimates.

I work natively in InEight and AutoCAD, build my own Excel models, and read MAXIMO asset data where it matters. Mostly though, I care about clear thinking under deadline pressure and translating commercial complexity into decisions teams can act on.

Why work with me

Discipline, calm and the commercial instinct to know what matters.

The trade-craft of estimating is unglamorous; the impact isn't. What you'll get from working with me, distilled.

  1. On-time delivery

    Estimates landed when they're needed, through sprint windows, board cycles and tender deadlines.

  2. Defensible numbers

    Every line traceable to its source and method. Estimates that hold up under sponsor and audit scrutiny.

  3. Continuous learning

    Eight years in, still actively learning: new tools, new contracting models, new risk angles.

Service

My capabilities across the desk.

Four practice areas where I do my best work, across the full estimating lifecycle, from concept-stage budgeting to tender response and post-award cost management.

View case studies

Estimating & Costing

Bottom-up and parametric estimates for capital, operational and contingency works, built to stand up under sponsor and audit scrutiny.

  • Tender & concept-stage estimates
  • InEight modelling & benchmarking
  • Sensitivity & contingency analysis
01 / 04

Rail & Infra Delivery

Estimating support across RPV, LXRP and Franchise programs, covering operations trials, level crossings, training, signalling and track works.

  • Level crossing removals (LXRP)
  • Trial operations & commissioning
  • Driver training infrastructure
02 / 04

Commercial & Tender

End-to-end tender response. From scope review and supplier engagement to pricing strategy, contingency build-up and post-tender negotiations.

  • Tender pricing & positioning
  • Contract admin & variations
  • Supplier RFQ & standardisation
03 / 04

Reporting & Decision Support

Turning raw cost data into the structured packs project sponsors can act on, from estimate narratives to delay-cost models.

  • Sponsor-grade estimate packs
  • Cost data analysis & visualisation
  • Onboarding new estimators

Open to senior estimating & commercial roles

Looking for a progressive team in rail, civil or utilities, somewhere I can keep growing the technical-commercial muscle while contributing across estimating, tender and delivery.

Case study

Recent case studies in depth.

Three programs where I can show the work: problem, process, solution, result. Names anonymised where contracts require it; happy to walk through specifics in conversation.

Rail capital Featured

Project Support Services. Multi-year capital estimating for RPV

A multi-year program of project support services covering the full estimating lifecycle from concept through tender. The largest single program I've supported.

Problem
Complex multi-stream scope, multiple sponsoring entities, evolving requirements over a multi-year window.
Process
Stakeholder engagement across engineering, commercial & delivery; built InEight estimate models with sensitivity analysis.
Solution
Structured estimate packs at each gate, with traceable narrative and contingency build-up that survived sponsor review.
Result
Estimates accepted across sponsor and audit cycles; team capability built through onboarding and standards work.

Level crossing Civil & rail

NWPA High Street Level Crossing. Estimating through delivery

A signature LXRP grade-separation program in Melbourne's north-west. High-stakes civil works in a dense brownfield corridor with significant community and operator interfaces.

Problem
Tight community-impact constraints, brownfield civil complexity, and an aggressive program window.
Process
Site walks, scope decomposition with engineering leads, supplier engagement and stage-gated estimate refresh.
Solution
Phased estimate model that tracked scope evolution; rate library and supplier benchmarking for civil packages.
Result
Cost positions held through delivery variations; estimating discipline carried forward to subsequent LXRP packages.

Tender Process

Comdain: standardising tender response across an 8-month window

As Graduate Engineer & Estimator at Comdain Infrastructure, I worked across multiple major tenders and rebuilt the internal request-for-quote and document management discipline.

Problem
Inconsistent RFQ templates and document handling created supplier risk and slowed tender response cycles.
Process
Mapped existing flow with PMs and procurement; designed simplified templates and an electronic document management system.
Solution
Single-source RFQ & order templates; structured DMS with versioning and retrieval discipline.
Result
Reduced supplier-risk exposure; faster tender cycles; 4 major infrastructure contracts won over 8 months.
4 contracts won Cycle time reduced Risk reduced
My edge

The edge I bring to the desk.

Beyond the spreadsheets. The underlying capabilities that make my estimates land and my reports get read.

Practice

Estimating that holds up.

Eight years of bottom-up, parametric and benchmark estimating across rail, civil and utilities. The breadth to know when each method fits and when none do.
