Temporary Works Designer

Help Shape the UK’s Energy Future

Temporary Works Designer Opportunity with the Civil Works Alliance (CWA), Supporting Sizewell C

As part of the CWA (Civil Works Alliance), you will support the building of Sizewell C. Sizewell C will be a 3.2-gigawatt power station generating low-carbon electricity for around 6 million homes and will play a key role in our energy future, supplying reliable, clean electricity for at least 60 years. This role will be within the CWA Wide Section.

What will you do?

Prepare and review calculations, drawings, reports, sketches, models, design risk assessments and other technical deliverables in accordance with project requirements.

Advise site, office, design and construction teams on buildability, sequencing, construction methodology and safe, innovative and cost-effective temporary works solutions, including information to support Target Outturn Cost estimating.

Ensure compliance with CDM regulations, HSWA, LOLER, PUWER and the Balfour Beatty Temporary Works Management Procedure.

Ensure internal and subcontractor designs meet the temporary works design brief, required timescales and technical approval requirements, including Approval in Principle submissions for clients and external stakeholders.
