Spec-driven Materials Approval & QC for major infrastructure
Thousands of spec pages.
One interactive workflow.
Prioris turns normative materials and construction specifications — FHWA FP-24, HK CEDD GS, UK HA Manual of Contract Documents, Portuguese CE EP — into live compliance rules that drive Materials Approvals, Inspection & Test Plans and pouring records straight from your site tablet.
Fewer specialised engineers on the MA bench. Faster approvals. Zero missed V/NV limits.

The business case
Every hour an engineer spends copying clauses into forms is an hour not spent on engineering.
Materials Approval (MA) and Inspection & Test Plans (ITP) are the most-duplicated, least-differentiated paperwork on any major project. Prioris treats the normative spec as a computed ruleset — not a PDF — and drives every form, every acceptance check, every pour record straight from those rules.
| Pain point | Status quo | With Prioris | Delta | |
|---|---|---|---|---|
| MA cycle time | 4–8 hours per submittal · thousands per project | 30 min → 1 hour | ≥ 85% faster | |
| Materials engineers per project | 2–4 FTE specialised | 0.5 FTE generalist | ≈ 75% reduction | |
| Non-conformance caught at pour | Hours–days (paper field forms) | Live, on first truckload | Real-time | |
| Rejected pours · re-work cost | Full demolition + re-cast | 7-day strength early warning | 40–70% avoided | |
| Spec onboarding | 200–800 pages × human read | Assisted ingestion * | Scalable to any spec | |
| Payment withholdings (LDs) | Frequent — no audit trail | Traceable V/NV trail · audit log | Contract-grade evidence |
* Spec ingestion workflow currently in development — will accelerate onboarding of new jurisdictions into the rules engine.
How Prioris works
From spec clause to site verdict — one rule engine.
No configuration screens. No form-builder. The normative spec itself is the configuration.
01
Apply the spec
Pick the jurisdiction and table (e.g. FP-24 §552 Concrete). Prioris loads every clause, test method, acceptance criterion and frequency into the project rules engine.
02
Auto-generate Materials Approvals
The MA form morphs per clause — Total SCM, w/cm, chloride limit, aggregate gradation — all evaluated server-side against the active clause set. The engineer reviews the decision, not the data-entry.
03
Spec-driven ITPs for QC
The same ruleset exposes a per-checkpoint ITP tree: CP1 aggregate source, CP2 trial mix, CP3 plant QC, CP4 pouring records, CP5 compressive strength. Each opens the matching data-capture surface.
04
Site technicians fill records in real time
On tablets at the point of discharge — slump, temperature, air content, sample ID. Values are tinted green / red as the technician types, using the clause's exact V/NV limits.
05
7-day strength prediction
As cube data comes back from the lab, the statistical prediction engine flags pours trending below 28-day target. Early warning reduces re-work windows from weeks to days.
06
Governance across portfolios
Platform Creator, Project Admin, EoR, RE, Contractor Engineer, Technician, Consultant, Asset Owner — role-scoped RBAC with seat limits and full audit trail. Same governance model across every asset.

Materials Approval · FP-24 §552
The submittal drawer auto-computes Total SCM from fly ash + silica fume + slag. Cement content, w/cm, chloride limit, aggregate gradation are all evaluated live against the selected clause. Reject / approve cycles include audit trail for contractual evidence.

Quality Control · 5 control points
CP1 Aggregate source · CP2 Trial mix · CP3 Plant QC · CP4 Pouring records · CP5 Compressive strength. Each checkpoint surfaces its acceptance criteria, test method and frequency — and opens the corresponding data-capture view.

Pouring Records with live V/NV flagging
Technicians log truckload by truckload: arrival time, plate, ticket, slump, temp, air, sample ID, photos. Slump 50 mm turns the cell green; temperature 40°C turns it red — instantly, before they hit Save.

On track (6) At risk (0) Below target (1)
P5 flagged below target at day 7 — the 28-day confidence cloud dips under f'c=35 MPa for the entire CI envelope, triggering an alert to the Resident Engineer 21 days before the 28-day cube break.
Both surfaces are spec-driven: column set, acceptance bands and statistical priors come from the applied FP-24 §552 table — not from hand-coded logic.
Who gains what
Value by stakeholder.
Prioris is adopted at the project level, but the value accrues across the full delivery stack.
| Stakeholder | Primary value | Headline KPI |
|---|---|---|
| Asset Owner / Government | Contractual evidence of conformance. Audit trail on every MA and pour. | Zero-dispute hand-over |
| Engineer of Record | Focus on engineering decisions, not spec transcription. Approvals in hours. | ≥ 90% MA cycle-time cut |
| Resident Engineer / PM | Live view of site conformance. Instant NV alerts at point of discharge. | Real-time NV detection |
| Contractor · Materials Engineer | No more manual RAM typing. Lower headcount, same throughput. | ≈ 75% FTE reduction |
| Contractor · Technician | Tablet-first pour logs. Green/red typing flags reduce re-work. | 40–70% re-work avoided |
| Testing Consultant | View + comment across MA and QC with scoped RBAC. | Scoped advisory access |
Normative coverage
Pre-loaded country specifications.
The spec library ships with major concrete specifications already modelled as computed rules. New contractual specifications can be onboarded quickly, with additional automation in development.

Who it's for
Built for major infrastructure projects.
Highway infrastructure · tunnels · marine works · rail · high-rise. Anywhere the spec matters and the volume is too big for paper-based MA / ITP.
Government road admins
Contract-grade evidence of supplier & contractor conformance across every asset in the portfolio.
Main contractors
Lower materials-engineering headcount. Faster RAM cycles. Transparent site NV resolution.
Engineers of Record
Approve on the engineering substance, not the paperwork. All decisions leave an audit trail.
Resident / Project Managers
Live conformance view. Intervene on the first truckload, not after a failed 28-day cube.
