AI-native preconstruction

Turn a tender package into a costed BOQ in hours, not weeks.

Preckon reads your tenders, drawings and specs, then generates the bill of quantities, the estimate and the procurement package — end to end. Every number traceable to the line it came from. Every step reviewed by your team.

Built with practicing estimators and quantity surveyors — not a demo reel.

The shift

Estimating shouldn't take longer than the bid window.

Today the estimate lives in a senior estimator's head and a sprawl of spreadsheets. It's slow, hard to staff, and impossible to audit. Preckon turns the same documents into a structured, defensible chain.

Today · 2–6 weeks per bid
  • 01 Print, mark up and measure drawings by hand
  • 02 Rebuild the BOQ in spreadsheets, every time
  • 03 Chase rates and prices across emails
  • 04 Knowledge locked in one estimator's head
  • 05 No trail from a number back to the drawing

Documents AI BOQ Estimate Procurement

One continuous chain from raw tender to procurement package — measured, costed, and reviewable at every step. Nothing auto-commits; your estimators stay in control.

The platform

Six modules. One continuous chain.

Each module is an intelligence layer. Together they carry a project from the first tender document to a ready-to-issue procurement package — orchestrated by the Construction Copilot.

01 / 06
TenderLogix
Tender Intelligence

Reads tender packages, scope and contracts. Extracts requirements and structures the project.

02 / 06
DrawLogix
Drawing Intelligence

Interprets drawings in PDF and CAD, recognizes building elements and measures them.

03 / 06
DocLogix
Specification Intelligence

Parses specifications and ties each clause to the elements and line items it governs.

04 / 06
QuantLogix
Quantity Intelligence

Generates the BOQ and takeoff from drawings and specs — measured and structured.

05 / 06
CostLogix
Cost Intelligence

Turns quantities into a costed, defensible estimate with rates you can trace and adjust.

06 / 06
ProcureLogix
Procurement Intelligence

Produces procurement packages and RFQs straight from the costed estimate.

Construction Copilot

The conversational layer across all six modules. Ask it anything about the project, trace any number to its source, and keep a human in the loop on every output.

Explore the platform
How it works

Upload. Analyze. Review. Generate.

A workflow your estimators recognize — with AI doing the measuring and your team keeping the judgment.

1

Upload the set

Drop in the tender, drawings and specifications — PDF or CAD.

2

AI reads & measures

Elements are recognized, quantities measured, specs matched to items.

HUMAN-IN-LOOP3

Review & correct

Your estimators confirm or adjust. Every change is captured and learned.

4

Generate outputs

BOQ, estimate and procurement package — exported, traceable, audited.

The intelligence layer

One orchestrator. Many providers. Your data isolated.

Underneath the modules sits a construction knowledge graph and a provider-independent AI orchestrator — so the platform reasons about real construction, not generic text, and never depends on a single AI vendor.

AI orchestrator

Routes each task to the right model and tool.

Knowledge graph

Construction logic, not generic language.

Provider independence

No lock-in; no single vendor sees all data.

Explainable & reviewed

Every output traceable; nothing auto-commits.

Learns from your estimators' corrections

Project-management platforms manage a BOQ once it exists. We generate it. They start where you finish.

Industries

Wherever the work starts with a drawing.

If a project is priced from drawings and specifications, Preckon reads it. The chain is the same; the templates and standards adapt to the sector.

Commercial

Offices, retail and mixed-use developments.

Infrastructure

Roads, bridges, utilities and transit.

Industrial

Plants, warehouses and manufacturing.

Healthcare

Hospitals and complex clinical facilities.

Government

Public works with audit and compliance needs.

Education

Schools, campuses and research buildings.

Residential

Multi-unit and large-scale housing.

Security & trust

Your tender documents never leave your control.

Sensitive bids and designs demand more than a feature list. Security is built into how the platform handles every document.

Isolated by tenant

Row-level separation. One client's data never touches another's.

Not used to train shared models

Your documents stay yours. Encrypted in transit and at rest.

Provider independence

Multiple AI providers, no lock-in — and no single vendor seeing everything.

Audited end to end

An immutable trail of who changed what. SOC 2 in progress.

Pricing

Pay for the platform. Pay for what you run.

A plan for the team, plus usage-based AI for the work itself — so cost tracks the volume of drawings, BOQs and estimates you generate.

Questions

The things estimators ask first.

Does this replace our estimators?
No — it removes the manual measuring and the rebuild-from-scratch work so your estimators apply their judgment to more bids. Review is a required step, not an optional one. Nothing is costed or issued without a person confirming it.
How accurate is it?
Every quantity is measured from the drawing and traceable back to the element it came from, so a reviewer can audit any number in a click. Your estimators' corrections are captured, and the system gets sharper on your standards and your project types over time.
What happens to our tender documents?
They stay yours. Data is isolated per tenant, encrypted in transit and at rest, and never used to train shared models. The platform is provider-independent, so no single AI vendor sees everything. More on security →
What file formats can it read?
PDF and CAD drawings, full tender packages, and written specifications. Drop in the set you'd hand an estimator and the platform reads the same documents.
How quickly can we see it on our own project?
Bring one drawing set to the first call and watch it run live, end to end. The Design Partner Program is the fastest way to run real bids through the full chain with the team alongside you.
