- NZ food & beverage processing
- Scope reviewed
- Industrial mechanical pipework, utility services, brownfield expansion
- Engagement
- Lean cost build-up, commercial review, nine-revision submission support
The problem: A subcontractor preparing a competitive tender needed a defensible cost build-up that could survive client lean-procurement scrutiny - across an 82-item photo-to-scope register, multiple supplier inputs, and rapidly evolving scope.
What we did: Structured the cost build-up into a single source of truth, ran the submission through nine revision cycles, populated the client's lean cost annexure, and conducted scope-to-photo reconciliation to close gaps between drawings, site evidence, and pricing logic.
Result: Submission tightened to a lean-defensible range without abandoning margin position. Scope risk visible to the tender team before submission, not after award.
"Lean tendering doesn't reward the cheapest number. It rewards the one you can still defend in week 12."

Common questions
Practical answers before you send through a file.
Who actually does the work?
Simon does all the commercial review work himself. Positive Earth Growth Hub is a single-operator practice - no junior estimator, no outsourcing, no offshore team. Simon is a senior engineer, QS, and commercial advisor with industrial mechanical, piping, and fabrication background across NZ food processing, infrastructure, and brownfield plant projects.
How is confidentiality protected?
Mutual NDA is standard on every engagement once project data is shared, and available within 24 hours on request for any engagement below that. Project files are held on Simon's own systems, never shared with third parties, and deleted on request after delivery. No project information is ever reused or referenced without full anonymisation and client agreement.
Is there a conflict of interest if you also work in industry?
Positive Earth Growth Hub doesn't bid against the businesses it reviews. If a potential conflict is identified during scoping - for example, an overlap with an active project on the engineering consultancy side - the engagement is declined and you are told before any project data is shared.
What size projects do you review?
Most useful where the work carries enough complexity, risk, or repeat value to justify structured commercial review.
What do I send you to get started?
The most useful starting pack is: drawings or scope notes, the current quote or commercial file (Excel preferred), any supplier or subcontractor quotes, and the client tender or RFQ pack if there is one. Bullet-point context emails are fine - anything missing, we'll ask for it.
What if you don't find anything wrong with my quote?
That's a real outcome - and one worth paying for. You receive a written commercial-defensibility note confirming the quote stands up, with any low-priority observations noted. In practice, most engagements surface something useful - even tightening exclusions or assumptions has commercial value at submission stage.
What's the difference between a one-off audit and the retained service?
Defined briefs handle a single quote, tender, or workflow problem. Ongoing support can be shaped privately where the business has repeated commercial review needs.
How are deliverables formatted?
Written commercial review notes (Word or PDF), marked-up Excel where relevant, structured workbooks built for direct use, and a clear action list. Everything is formatted to drop straight into your estimating, commercial, or project workflow - not academic reports nobody reads.
More on Scope & BOM
What software do you build BOMs in?
Microsoft Excel is the primary delivery format, structured for compatibility with most NZ procurement and commercial systems. SolidWorks 2022 Premium is used for take-offs that need 3D model interrogation. DXF, DWG, PDF drawings, and Deepnest nesting outputs are all supported as inputs.
Can you work directly from messy drawings and PDFs?
Yes. Drawings (PDF, DWG, DXF), scope notes, site photos, and supplier specifications can all be used as inputs. The output is a structured, submission-ready workbook regardless of how disorganised the input pack is - most engagements start with a mix of drawings and emails.
Will your BOM integrate with my existing commercial system?
Yes - the workbook structure is designed to drop into existing Excel pricing engines or quote systems. If you have a custom workbook, we match its column logic. If you don't, we can provide a clean structure as a baseline you can use across future quotes.
