Temporary Works Consulting & Design is a structural engineering practice. We design, check and control the temporary condition — so the permanent works go in safely and the programme holds.
- Data centres
- Overhead power lines
- Substations
- Structural alterations
- Hoardings
The control scale
Cat 0 to Cat 3 — the check the job actually needs
- 01Cat 0Standard solutions, competent review
- 02Cat 1Simple design, independently checked
- 03Cat 2Complex schemes, formal check
- 04Cat 3High consequence, third-party check
The practice
Design that is buildable before it is beautiful
- Maximise utilisation of the programme
- Produce issue-ready packs at site pace
- Unlock the next lift, pour and strike
Multiple divisions. One practice.
Design, checking, tools and training.One practice. One domain.

Beyond construction: The Crude Oracle — crude oil intelligence without the noise, from the same stable of projects.
Structural engineering built for the site
Design, checking and site control under one roof — data centres, overhead power lines, substations, structural alterations and hoardings.

Case studies
Real temporary works, from brief to close-out
The representative project is real and anonymised for confidentiality; the further examples are illustrative and generalised. No client or project is identified.
- 01Energy plant
Omitted braced-bay steel during generator installation
Major London airport energy project. Braced-bay steel had to come out at two plant towers so generators could be installed — removing part of the frame's lateral stability and clashing with the lift envelope. A staged temporary bracing scheme replicated the omitted load path, the bay became a designed lift corridor, and the tier-one permanent works engineer accepted the strategy for delivery.
- 02Structural alterations
Late propping scheme on a refurbishment
A propping arrangement was needed quickly to keep a strip-out on programme. Calculations and details were prepared and issued for checking with a clear design brief and residual-risk notes — the scheme reached competent check without holding the job.
- 03Piling & groundworks
Piling mat for a tracked rig
A working platform was required before a piling rig could mobilise. Platform assessment with reference to BR 470, subject to ground information, with permit-to-load input — a clear platform basis and certificate input for sign-off.
- 04Scaffold interfaces
Scaffold interface coordination
A designed scaffold interacted with propping and excavation near the structure. Ties, loads and ground bearing were reviewed and coordinated across trades — clearer design responsibility and a coordinated interface.
- 05Principal contractor
Setting up BS 5975 control
A new project needed a workable temporary works procedure and register. Procedure, register template and role guidance were delivered with reference to BS 5975:2024 — a practical system the team could actually run.
- 06Infrastructure
Virtual audit for a remote project
An external check on temporary works control was wanted without a site visit. A remote audit used photos, records and a video walk-round against the register — ranked findings and priority actions, delivered quickly.

FAQ
Temporary works design, answered plainly
What is temporary works design?
Temporary works design covers the engineering of structures used only during construction — such as excavation support, propping, formwork, falsework, hoardings, and working platforms — required to be designed and checked under CDM 2015 and BS 5975.
Do you provide temporary works design across the whole UK?
Yes — our design and compliance support is delivered remotely, so we support contractors and subcontractors on projects anywhere in the UK.
How does your remote temporary works service work?
You send us your brief via our web form or WhatsApp, we provide a fixed-price quote, and deliver a full design pack — calculations, sketches, drawings, and design risk assessments — remotely and on a fast turnaround.
Can you support ongoing projects with a retainer instead of one-off quotes?
Yes — we offer a weekly support retainer for contractors who need ongoing temporary works design and compliance support across live projects, alongside fixed-price one-off project quotes.
What does BS 5975:2024 compliance support include?
We help contractors meet BS 5975:2024 obligations including procedures, registers, and clearly defined roles such as the Designated Individual and Temporary Works Coordinator, plus independent-style design check coordination.
Standards
Temporary Works: Key Facts & Standards
The standards, legal duties and check categories that sit behind every design pack we issue.
- 01
BS 5975:2024
In February 2025, BSI split the former BS 5975:2019 standard into two parts: BS 5975-1:2024 (management procedures for the control of temporary works) and BS 5975-2:2024 (falsework design and implementation) — the update every UK contractor now needs to comply with.
Source: BSI, 25 February 2025.
- 02
Construction remains the UK's highest-fatality sector
HSE recorded 25 construction worker deaths in work-related incidents in 2025/26, with falls from height the leading cause across all sectors.
- 03
Legal duty under CDM 2015 and HSE guidance
Any temporary structure "must be designed, installed and maintained to withstand any foreseeable loads which may be imposed on it," and inspected regularly by a competent person.
- 04
Independent design checking (Cat 0–3)
A recognised categorisation for temporary works checks, ranging from self-check (Cat 0) to full independent check by a separate organisation (Cat 3), scaled to project risk.
Source: BS 5975 design check categories.
