Substation Structural Engineering

Utility assets are operational, often decades old, and rarely can be taken out of service for convenience. Assessment and remedial design have to work around that.

Substation Structural Engineering

What we cover.

Substations, plant compounds and utility structures share a set of problems: ageing reinforced concrete, retaining structures holding back ground nobody has checked in years, plinths carrying equipment heavier than the original design, and restricted access for anything invasive. Our engineers have carried out inspection, remedial design and monitoring across multiple substation sites.

In detail

What substation structural engineering actually involves.

Retaining structures

Retaining structures are the recurring issue. Many were designed to superseded standards, some have been surcharged by later works, and their condition is rarely recorded. Assessing what is actually there and what it is holding back comes before any decision about repair or replacement.

Monitoring on live sites

Monitoring is often the proportionate answer on an operational site. Where movement is suspected but not established, tell-tales and a period of recorded observation produce evidence rather than opinion, and they do it without taking an asset out of service.

What is achievable

Remedial design on live sites has to account for what can realistically be done around the operation. A technically ideal repair that requires an outage nobody will grant is not a solution, so we set out what is achievable alongside what is optimal.

How Lead Group helps

We assess retaining structures designed to superseded standards and establish what they are actually holding back before recommending anything. On operational sites we will propose monitoring where movement is suspected but unproven, and we set out what is achievable around the operation alongside what would be technically ideal.

How we work

Can assessment be done without taking the asset out of service?

Usually a good deal of it can. Visual and non-intrusive inspection, tell-tale monitoring and recorded observation over a period all work around an operational site. Where intrusive investigation is genuinely necessary we say so and scope it tightly, rather than specifying an outage as a matter of course.

Standards & codes

The codes behind substation structural engineering.

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

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 inspect multiple sites to one standard?

Yes. Consistent reporting across a set of assets is what allows them to be compared and prioritised.

Do you assess retaining walls?

Yes, including reinforced concrete retaining structures where the original design standard is superseded or the records are missing.

Do you provide monitoring?

Yes, including tell-tale installation, recorded observation and reporting on whether movement is occurring and at what rate.

Can you produce bills of quantity for remedial works?

Yes, alongside the remedial design where that is useful for procurement.
