The OLE tools we wished existed — so we built them

We're an OLE consultancy first. Each tool is shaped by front-line delivery, governed by source, and framed honestly — in development, in build or review-required. The discipline is the product.

OGMS

Governed OLE Management System
In development

An end-to-end OLE tool for front-line and technical teams. It searches and breaks down drawings instantly, builds technical reference packs, and generates material schedules ready for maintenance and construction — with paperless site survey, dropper, catenary, coasting and isolation all held in one governed record that traces back to source.

Who it's for · Front-line and technical teams — maintenance, construction and design
Every output REVIEW_REQUIRED · source-led · no admitted safety-critical truth without a competent OLE checker-approver.

Dropper Calculator

Per-span dropper schedules
In build

Per-span dropper schedules, system-height-aware. Single-dropper isolation and full-span replacement modes, with a checked schedule traceable to its inputs.

Who it's for · OLE engineers producing and checking dropper schedules
Hs 1980 mm is nominal, family-gated to UK1 Mk1 3xx only · unknown system heights stay null / review-required, never fabricated.

IsoPlan

Intelligent isolation planning
Review-required

Intelligent isolation planning — a DEP register and isolation case engine that helps teams build and check isolation plans, source-recognised and joined cleanly back to the record.

Who it's for · Isolation and E&P teams planning and checking isolations
Governed — review-required · source-recognised · no isolation boundary presented as authoritative.
Digital tools

Got a process stuck in a spreadsheet? We build the tool.

Case study

Much of OLE delivery still runs on ageing spreadsheets and disconnected legacy tools. We design digital tools around your requirements — moving that manual practice into governed systems, usable in the office or remotely, and linked to the systems you already run.

Today
Re-keyed by hand between disconnected systems
No single source of truth or audit trail
Tied to one desk, one machine, one person
Knowledge locked in spreadsheets and individuals
With a digital tool
Paperless capture, in the office or on site
One governed record, source-led and traceable
Integrates with the systems you already run
Review-required by default, fully auditable

How it starts · It's how one of our tools began — a painful, manual planning job spread across legacy systems. We formalised the process, then applied technology to take the pain out: a source-recognised model, reused across multiple planning and delivery uses.

The posture

Review-required is a feature, not a disclaimer

No tool implies certification, or operational, geometry, topology, isolation or source-truth authority. The owner is the OLE subject-matter authority on every claim.

Source-led — every output traces to the documents it was built from.
Checker-approver — a competent OLE engineer signs off safety-critical truth.
Datum-honest — unknowns stay null and flagged, never fabricated.
Auditable — reviews and sign-off are built into the workflow.
