Hands-on delivery, commercial and tender support — from people who've run the work.
G12 backs contractors where the pressure is: contract administration, variations and claims, estimating and tender submissions, technical advisory. Every engagement runs on the same integrated management platform we build for clients in their own Microsoft 365 — so the records, the registers and the evidence are always there when it counts.
Pressure shows up the same way on every job
The work is good. The records, the commercial position and the next bid are where it slips.
The programme is slipping and the variations register is three weeks behind the conversation on site.
The claim is strong — but the correspondence, notices and daily records to back it aren't.
Tender documents are rebuilt from scratch every time because nobody can find the last submission.
Specifications sit in someone's inbox while the crew works from last month's revision — and the audit is next month.
Two streams, one discipline
Management consulting first, platform build behind it — hands-on support running the work, and the systems the business runs on. G12 doesn't construct, so there's never a conflict with the contractors we serve.
Consulting & delivery support
Project delivery & commercial support
Engineering-led support keeping delivery and the commercial position under control — before variations and claims become the distraction.
- Contract administration, correspondence and notices
- Variations, claims and progress reporting
- Programme, cost and document discipline on live jobs
Bid & tender support
From opportunity to submission — priced, written and evidenced properly.
- Estimating and pricing for ground engineering scopes
- Tender writing, methodology and submission assembly
- Pipeline and opportunity tracking as a system
Technical advisory
Independent, delivery-literate advice from people who've run the work.
- Methodology and specification review — rope access, rockfall, sprayed concrete, anchors
- ISO 9001 / 45001 / 14001 system design and audit readiness
- Systems and information architecture advice before you commit
Platforms
Integrated management platforms
The core offering: a hub-and-spoke SharePoint platform covering the functions a contracting business actually runs on, aligned to ISO 9001, 45001 and 14001.
- Document control and controlled registers
- Plant & equipment, maintenance and prestarts
- Correspondence and specifications tracking
- Compliance, tenders and bids
Automation & integration
The platform does the chasing so your people don't have to.
- Power Automate workflows — approvals, registers, notifications
- Microsoft Graph and PowerShell for the jobs the UI can't do
- Power BI reporting over live operational data
Tenant setup & migration
Getting the foundations right — or moving off the wrong ones.
- Microsoft 365 tenant setup and Entra ID governance
- Migration from Google Workspace and legacy file shares
- Security, licensing and information architecture done once, properly
Three principles, every platform
One hub, many spokes
A central hub carries the standards; each function and each client site is its own spoke. One copy of any document, one library per purpose — no duplication, ever.
Your tenant, your data
Everything is built inside your Microsoft 365 environment. If G12 disappeared tomorrow, your platform keeps running and you own every part of it.
Governed from day one
Naming conventions, version control, permissions and document numbering are designed in at the start — not bolted on before the audit.
Your management system. Built in your Microsoft 365. Owned by you.
What makes G12's consulting stick: every engagement can land as working systems in your own tenant — one environment, every function connected. No third-party lock-in. Your tenant, your data.
Live platform tools
Beyond the management platforms we build inside your own tenant, G12 runs a set of purpose-built tools that show the same discipline at work — for tendering, field operations and estimating.
Tender Tracker
Search, track and manage the tender pipeline in one place — from identified opportunity through to submission, with Microsoft 365 sign-in.

Job Control
A field app for day sheets, job records and subcontractor compliance — connected to your document register and payroll.

FPS Working Pressure Calculator
Rig bearing-pressure and working-platform certification for piling and drilling rigs, to the UK FPS calculation basis.
Learn more →Estimating Tool
A web-based estimating tool for ground engineering tenders — quantities, trade pricing and a returnable schedule, built the same way as the rest of the platform.
Learn more →Engagement models
From a fixed-scope build to ongoing platform management — sized to the business, not the other way round.
Platform build
Fixed-scope design and deployment of your integrated management platform, handed over documented and working.
Embedded management
G12 runs and develops your platform as your systems arm — administration, automation and continuous improvement.
Delivery & commercial support
Hands-on support on live jobs — contract administration, variations, claims, reporting — for a project, a pinch point or a season.
Advisory
Independent, engineering-literate advice on methodology, systems and ISO alignment — before you commit to anything.
Built for the contractors we come from
G12 was founded from decades of hands-on ground engineering delivery. The platforms are shaped by how this work actually runs.
Platforms in the field
Australian Slope Retention
A full integrated management system built inside ASR's own Microsoft 365 environment — from tenant governance through to the registers the crews use daily.
- Hub-and-spoke SharePoint platform across document control, plant, specifications and correspondence
- Controlled document numbering and version control from day one
- Owned and operated in ASR's tenant — no third-party platform fees
Ropecrete Geotechnical
Platform deployment underway on the same hub-and-spoke model — starting with the move that matters most: getting off the wrong foundations.
- Migration from Google Workspace into a governed Microsoft 365 tenant
- Business development, tender tracking and estimating built as a system
- One copy of any document, one library per purpose — enforced by design
Built by people who've run the sites, not just the software
G12 Consulting was founded on decades of hands-on ground engineering delivery — rope access, rockfall protection, sprayed concrete and slope stabilisation work across Australia. That delivery discipline is now pointed at the systems contractors run on. G12 doesn't construct: the boundary is platform build and management consulting, which means no conflict with the contractors we serve.
