Engineering & Delivery
Designed as a system, accepted as evidence.
PrecisionX engineers the operating system for your estate and coordinates the specialist disciplines around it — engaging licensed professionals for the work that legally requires them — then proves it works through factory and site acceptance before you depend on it.
Critical infrastructure is engineered, not assembled
Every deployment is designed against real dependencies, explicit authority boundaries and a documented acceptance path.
Design authority is explicit from day one
We start by naming what must remain authoritative — protection, safety, existing BMS/SCADA and customer standards — and design PrecisionDCOS as an accountable overlay around them. Nothing safety-critical is made to depend on the operating system.
Engineering disciplines
PrecisionX owns the operating-system integration and coordinates specialist disciplines as one coherent system rather than a stack of independent tools.
Controls & instrumentation
Network & OOB
Electrical & power
Mechanical & cooling
Software & integration
Security & compliance
Licensed-professional boundary
PrecisionX does not self-certify every discipline. Stamped electrical, structural, mechanical and fire/life-safety engineering, and any work reserved to licensed trades, is performed or sealed by the appropriately licensed professionals. PrecisionX owns the operating-system design and integration and coordinates those professionals so the disciplines resolve into one accountable, accepted system.
The 13-stage delivery lifecycle
A staged path with defined gates — nothing advances until the prior stage is accepted on evidence. FAT and SAT are hard gates.
- 1Discovery & requirements
Estate survey, existing systems, standards, constraints and success criteria captured.
- 2Basis of design
Authority matrix, scope boundaries, control classes and design assumptions agreed.
- 3Detailed engineering
Points, I/O, network, power, integration and security engineered to issued-for-construction detail.
- 4Design review & approval
Cross-discipline review; licensed professionals stamp the work that requires it.
- 5Procurement & staging
Long-lead items, hardware and controlled firmware baselines procured and staged.
- 6Build & integration
Racks, panels, enclosures and software integrated and configured against the design.
- 7Factory Acceptance Test (FAT)
Functional testing to documented criteria before anything ships. Hard gate.
- 8Delivery & installation
Field installation, structured cabling, power and network termination and labeling.
- 9Commissioning
Point-to-point verification, loop checks and signal-quality validation on site.
- 10Site Acceptance Test (SAT)
Power, network, out-of-band and monitoring verified in place. Hard gate.
- 11Operational readiness review
Runbooks, escalation, authority boundaries and evidence confirmed before go-live.
- 12Handover & go-live
As-builts, baselines and the operating contract activated; site declared operational.
- 13Continuous improvement
Post-deployment review, RCA feedback and iterative engineering under change control.
Deliverables produced across the lifecycle
- Basis of design and authority matrix
- Issued-for-construction drawings and point/I-O schedules
- FAT and SAT plans, scripts and signed results
- Commissioning and loop-check records
- As-built documentation and controlled firmware baseline register
- Operational readiness runbooks and escalation paths
Industrial Edition engineering
Substation, water/wastewater, energy and process environments carry additional engineering discipline.
Zone-and-conduit segmentation
Environmental & hazardous-area rating
Protection stays autonomous
Commissioning with plant trades
Standards & safety boundaries
Engineering respects control classes and keeps protective functions local and independent.
Control classes are honored
Data quality is modeled
Firmware baselines are controlled
Evidence is designed in
Operational readiness handover
A site is declared operational only after readiness is demonstrated and the operating contract is in force.
- 1Site Acceptance Test verifies power, network, out-of-band and monitoring against documented criteria.
- 2Runbooks, escalation paths and authority boundaries are confirmed with the operating team.
- 3Baseline evidence, as-builts and firmware levels are recorded and handed over.
- 4The operating contract — response, change cadence and reporting — is activated.
Frequently asked questions
Disciplines, licensing, delivery gates and Industrial Edition engineering.
- Does PrecisionX engineer every discipline itself?
- No. PrecisionX owns the operating-system design and integration and coordinates the specialist disciplines. Stamped electrical, structural, mechanical and fire/life-safety engineering, and any licensed-trade work, is performed or sealed by the appropriately licensed professionals.
- What are the hard gates in delivery?
- The Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) are hard gates. Nothing ships without a passed FAT, and no site is declared operational without a passed SAT and an operational readiness review — each accepted on documented evidence.
- How many stages are in the lifecycle?
- Thirteen — from discovery and basis of design through detailed engineering, procurement, build, FAT, installation, commissioning, SAT, readiness review, handover and continuous improvement. Each stage has defined entry and exit criteria.
- How is Industrial Edition engineering different?
- It adds zone-and-conduit OT segmentation, environmental and hazardous-area rating, and commissioning coordinated with licensed plant trades — while protection, gas and shutdown systems remain locally autonomous.
