RESOURCES
Engineers First. Built by People Who’ve Been on Your Side of the Table.
Precon was not built as a services company.
It was built out of project pressure.
We’ve sat in estimating rooms late into tender deadlines.
We’ve coordinated BIM models that arrived incomplete.
We’ve priced work with evolving drawings, tight programmes, and real commercial risk.
That experience shapes everything we do.
We are engineers first — estimators, BIM coordinators, planners, detailers — supporting other
engineers, architects, contractors, and consultants. Not as an external vendor, but as an extension
of the teams delivering the work.
Our teams operate across regions and procurement models, working strictly to the measurement systems recognised locally by contractors, consultants, and employers. We do not normalise or simplify standards. We follow the rules that govern the project. Measurement is treated as a commercial discipline, not a drafting exercise.

- Elemental and work-item–based measurement commonly used for public works
- Contractor-specific breakdowns for private-sector and EPC projects
What This Means for Our Clients
- UK & Irish teams receive quantities in NRM / ARM / CESMM formats they already trust
- International EPCs and developers see outputs aligned to regional statutory standards
- No loss of intent between estimating, procurement, and commercial review
- Assumptions, exclusions, and scope boundaries remain transparent and auditable
We do not impose our own measurement logic.
We adapt to yours.
Every service we deliver follows the same core principle: clear ownership, technical oversight, and independent quality control.
We currently operate with a team of 120+ engineers, planners, QS, BIM specialists, and technicians, structured by discipline and scale.
01
Estimation, Take-Offs & BOQs
Team Structure
- Lead Estimator: Sets measurement methodology, confirms scope boundaries, aligns with client standards.
- Estimators / QS Engineers: Deliver trade-based take-offs, BOQs, elemental cost plans, and bid comparisons.
- Commercial QA Reviewer: Independently checks quantities, assumptions, exclusions, and internal consistency
Workflow
- Scope & measurement alignment
- Trade-by-trade quantification
- Internal technical review
- Independent commercial QA
- Final issue with assumptions register
02
BIM / VDC & Digital Engineering
Team Structure
- BIM Manager / Digital Lead: Owns BEP alignment, LOD/LOI, coordination strategy.
- Discipline Modellers (Arch / Str / MEP): Develop models and manage interfaces.
- Model QA & Coordination Reviewer: Reviews geometry, data integrity, naming, coordination status.
Workflow
- BEP and standards confirmation
- Discipline modelling
- Clash detection & coordination
- Technical model QA
- Issue of federated outputs
03
Construction Documents & Specialist Drawings (Including Joinery)
Team Structure
- Package Lead / Senior Technician: Reviews constructability, tolerances, sequencing.•
- Detailers / Drafting Engineers: Produce shop drawings, fabrication details.
- Package QA Reviewer: Checks dimensions, interfaces, buildability.
Workflow
- Design intent review
- Drafting & detailing
- Coordination check
- Independent QA
- Fabrication-ready issue
04
Scheduling & Project Controls
Team Structure
- Planning Lead: Defines programme logic, phasing, milestones.
- Schedulers / Planners: Develop L2–L5 programmes, lookaheads, procurement schedules.
- Programme QA Reviewer: Reviews logic ties, durations, critical path.
Workflow
- Scope & methodology alignment
- Baseline programme development
- Logic and risk review
- Independent QA
- Issue and update cycle
Quality is not a single checkpoint at the end.
It is built into every stage.
QC Levels on an Active Project
On an active project, each deliverable typically passes through 3 distinct checks before issue.
Discipline Review
Conducted by the Lead (Estimator, BIM Lead, Planning Lead)
Independent QA Review
Performed by a senior team member not involved in production
Final Sanity Review
Confirms clarity, usability, and construction readiness
Who Performs QC
On an active project, each deliverable typically passes through 3 distinct checks before issue.
01
Senior Estimators (8–15+ years experience)
02
BIM Managers / Coordinators
03
Planning Leads
04
Discipline Specialists with delivery background

Why This Matters to You
Precon exists because projects don’t fail due to lack of software or resources. They fail when teams don’t have the right support at the right moment.
We’ve been on your side of the table. That’s why our work feels familiar, dependable, and grounded in reality
