Checking & Peer Review

Independent structural checking, peer review and third-party checking for Building Control, plus expert witness reports.

Checking & Peer Review

What we cover.

A second set of qualified eyes catches what a single designer can miss. We provide independent checking and peer review of structural designs, third-party checking for Building Control, design verification and expert witness reporting.

How we work

Why have a design independently checked?

Independent checking confirms the design is correct and complete before it is built, which reduces risk for everyone. For some projects a Category 2 or 3 check is required, and we provide that independent verification.

  • Independent design checking
  • Third-party checking for Building Control
  • Design verification reports
  • Expert witness services

Standards & codes

The codes behind checking & peer review.

Eurocodes 0-9 & UK National Annexes

BS EN 1990 through BS EN 1999 govern the basis of design, actions, and the design of concrete, steel, timber, masonry and aluminium structures. Every calculation we issue references the relevant Eurocode part and its UK National Annex, and states which parts were applied.

Analysis, design & drafting software

Structural analysis and design in Tekla Tedds and Tekla Structural Designer, with Autodesk Robot, CSC Fastrak, CSC Portal Frame, MasterSeries and Hilti Profis used where a scheme suits them. Drawing production in AutoCAD, and modelling in Autodesk Revit where a project is delivered in BIM. Output is issued as readable calculations rather than raw software printouts, so a checker or a building control officer can follow the reasoning.

Approved Document A (Structure)

The Building Regulations requirement your local authority Building Control checks against. Our calculations and drawings are prepared to demonstrate compliance so your submission is accepted without back-and-forth.

Professional indemnity insured

Every report and calculation package is backed by professional indemnity cover, which is what lets a lender, Building Control or another engineer rely on it.

Process

From enquiry to sign-off.

1

Enquiry

Send drawings or describe the problem. We confirm the scope, the deliverables and a target timescale.

2

Information

We agree the survey, drawings or data we need and any site access required.

3

Engineering

Design, calculation or assessment to the relevant Eurocodes and UK National Annex.

4

Issue

A clear, defensible report or set of calculations, with assumptions and limitations stated.

Selected work

Real structures, surveyed and engineered.

Questions

Common questions

Can you check another engineer's design?

Yes. We carry out independent checks and peer reviews of structural designs, and issue a verification report setting out what was checked and any findings.

Do you provide expert witness reports?

We prepare expert witness reports on structural matters, written to the standard required for use in proceedings.

What is third-party checking for Building Control?

It is an independent check of a structural design carried out on behalf of, or to satisfy, Building Control. We provide that check and the supporting verification.

Do you check for conflicts of interest before accepting a checking role?

Yes. We decline where we have a prior interest in the design, the site or a party involved, including where the original design came through a company connected to us, and we disclose any connection before accepting rather than after. A check is only worth what its independence is worth.
