The Structural Problem

Construction Systems Slowly Drift Apart

Every project moves through multiple systems. Each handoff slightly changes how costs are categorized, coded, or recorded.

Over time, those small differences compound until estimates, budgets, and actuals no longer align.

Stage 1 · Estimate

Estimators build the cost structure in estimating software and spreadsheets.

~40 hrs

average time to produce a tender

Stage 2 · Budget

Finance recreates the cost structure inside Business Central — manually.

3–5 days

to reconcile estimate into ERP

Stage 3 · Actuals

Field activity, labour, plant and materials flow in from Assignar and payroll.

The Result: You find out too late. And you never learn.

Each system uses slightly different cost codes, structures, and categories.

By the time the project finishes, the original estimate and the final actuals are no longer directly comparable.

The feedback loop that should improve future estimates is broken. Without a memory layer, the operational knowledge from that job — what worked, what didn't, who performed under pressure, which ground conditions drove cost — disappears entirely.

Three layers of memory

The data Demiton can read depends on what you have connected.

Universal MCP Interface

Ask Claude — or ChatGPT — about your projects. Demiton answers.

Demiton runs as an MCP server. Project financials, compliance status, and site diary intelligence — queryable from Claude today, ChatGPT in Q3 2026.

Why we built it

Every construction firm runs its estimate through one system, its field ops through another, and its payroll through a third. When the project finishes, the only person who knows what actually happened is the one who worked across all three. When they leave, the knowledge leaves with them. Demiton reads from all three, reconciles the result, and keeps the record. The memory stays.

Built on the Demiton procurement classification framework — open source, version-pinned. Released at Tech in Gov 2026.
