Construction

What is Construction?

A drawing set arrives as a few hundred pages of PDF. Somewhere inside it is a schedule, a bill of materials and a cost, and extracting them is weeks of careful, repetitive reading that a deadline usually shortens. Construction reads the set directly: it classifies sheets by discipline, extracts quantities and scope, correlates what the architectural, structural and MEP drawings each say about the same space, and produces a work breakdown, a dated schedule, an estimate and a procurement plan. Each number carries the sheet and region that produced it, so a quantity surveyor can open the drawing behind a figure and argue with it — which is the difference between an estimate a team will use and one they will quietly redo by hand.

Problems it solves

• Understand a large drawing set without reading every sheet by hand
• Extract quantities and scope with the sheet reference attached
• Build a work breakdown and schedule from project documentation
• Find where architectural, structural and MEP drawings disagree
• Identify information that is missing before it becomes an RFI on site
• Connect planning, procurement and execution to the same source documents

Key capabilities

Document Intelligence

Read long, structured documents — drawings, filings, specifications — and extract what matters with the page it came from.

Quantity Takeoff

Derive measured quantities from drawings, each tied to the sheet and region that produced it.

Schedule Generation

Turn scope into a work breakdown, dependencies and a dated schedule.

Cost Intelligence

Build an estimate from quantities and rates, showing which assumptions drive the total.

Discrepancy Detection

Surface where documents disagree with each other, before the disagreement reaches a site.

Procurement Planning

Convert a bill of materials into lead times, packages and an order calendar.

Evidence Trail

Every figure carries the record it came from, so a reader can check the answer instead of trusting it.

How it is built

Sheet recognition

Classifies drawings by discipline and sheet type so scope is organised the way the project already is.

Traceable quantities

Each quantity keeps the sheet and region it was measured from, so it can be checked rather than trusted.

Cross-discipline correlation

Compares what different disciplines say about the same space and reports where they disagree.

Schedule from scope

Derives a work breakdown, dependencies and a dated schedule from extracted scope.

How it works

How the work is structured, and what each step's output rests on.

1. 1

   Ingest the drawing set

   Source

   Take architectural, structural, civil and MEP drawings, specifications and schedules as issued.

2. 2

   Classify sheets

   Observed

   Identify discipline, sheet type and revision so scope maps to the project's own structure.

3. 3

   Extract scope and quantities

   Observed

   Measure and record quantities, keeping the sheet and region for each.

4. 4

   Correlate across disciplines

   AI-inferred

   Compare what each discipline says about the same space and flag disagreement.

5. 5

   Build the plan

   AI-inferred

   Produce a work breakdown, dependencies, schedule, estimate and procurement packages.

6. 6

   Attach the evidence

   Source

   Link every line back to the document that produced it.

7. 7

   Review and adjust

   Human-verified

   A person reviews, corrects and re-runs; corrections are recorded as human-verified.

Example use cases

Each example has its own page you can read and share.

Ask Construction

Illustrative examples. Results depend on your own data.

• “Create a preliminary quantity takeoff from these drawings.”
• “Build a WBS and project schedule from this drawing set.”
• “Identify discrepancies between the architectural and MEP plans.”
• “Which sheets is this concrete quantity derived from?”

Questions

Does it replace a quantity surveyor?

No. It produces a first pass fast enough to be useful and traceable enough to be checked. The judgement stays with the estimator.

What if a drawing is ambiguous?

It is reported as missing or conflicting information rather than resolved by assumption, because an invented dimension becomes a real cost on site.

Can I see where a number came from?

Yes — every quantity links to the sheet and region it was measured from. That is the core of the design.

What file formats does it read?

Drawing sets as issued, including PDF drawing sets, specifications and schedules.
