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.

How We Measure Work — Globally Aligned, Locally Fluent

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.

Measurement Standards We Work With

United Kingdom

  • RICS NRM
    • NRM1 – Order of Cost Estimating & Cost Planning
    • NRM2 – Detailed Measurement for Building Works
    • NRM3 – Maintenance & Lifecycle Costs
  • SMM7 (legacy projects)
  • CESMM4 – Civil Engineering Works

Ireland

  • RICS NRM (widely adopted)
  • ARM4 – Agreed Rules of Measurement
  • CESMM4 – Civil & Infrastructure

United States

  • CSI MasterFormat – trade-based measurement
  • Uniformat – conceptual and early-stage estimating
  • Contractor-specific work package breakdowns

UAE / Middle East

  • POMI
  • CESMM
  • Employer- or consultant-issued hybrid measurement rules
  • Package-based BOQs for EPC and design–build contracts

Australia

  • ANZSMM
  • SMM7 (legacy frameworks)
  • State- and authority-specific civil measurement schedules

Netherlands / Europe

  • NEN 2699
  • STABU
  • Elemental and trade-based hybrids aligned to procurement route

Hong Kong

  • HKSMM – Hong Kong Standard Method of Measurement
  • CESMM for civil and public infrastructure works
  • Authority-specific schedules for government projects

Singapore

  • SMM2
  • CESMM / PSSCO for civil and infrastructure
  • Trade-based BOQs aligned with local tendering practice

India

  • IS 1200 – Method of Measurement
  • CPWD / State Schedule of Rates alignment
  • Trade-based BOQs for EPC and private-sector delivery
  • Hybrid systems for international contractors operating locally

Japan

  • MLIT (Ministry of Land, Infrastructure, Transport and Tourism) Measurement Standards
  • Japanese Standard Estimation System (積算基準 / Sekisan Kijun)
  • 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.

Our Delivery Model — Built Like a Project Team

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

  1. Scope & measurement alignment
  2. Trade-by-trade quantification
  3. Internal technical review
  4. Independent commercial QA
  5. 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

  1. BEP and standards confirmation
  2. Discipline modelling
  3. Clash detection & coordination
  4. Technical model QA
  5. 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

  1. Design intent review
  2. Drafting & detailing
  3. Coordination check
  4. Independent QA
  5. 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

  1. Scope & methodology alignment
  2. Baseline programme development
  3. Logic and risk review
  4. Independent QA
  5. Issue and update cycle
Quality Control — How We Keep Standards Consistent

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

Measurement you recognise

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
