Scaffold Design Engineer: What They Do and How to Become One

A scaffold design engineer works out, by calculation, how a scaffold that falls outside the standard configurations will stand up and carry its load, then produces the drawings and design information the scaffolders build from. Loading bays, temporary roofs, cantilevers and bridges are the bread and butter. The job sits between engineering and the tools, and unlike most scaffolding jobs the way in is usually an engineering qualification rather than a CISRS card.

When the law says a scaffold needs a design

The starting point is the Work at Height Regulations 2005. Schedule 3 says strength and stability calculations must be carried out for scaffolding unless a note of the calculations covering the arrangement is already available, or the scaffold is assembled to a generally recognised standard configuration.

In practice, that standard configuration is one of two things:

• Tube and fitting: NASC's TG20:21 compliance sheets, which set out standard configurations that need no additional bespoke design. Our guide to TG20:21 explains how they work.
• System scaffold: the manufacturer's own guidance for its product.

HSE puts it plainly: unless a scaffold is assembled to a generally recognised standard configuration, it must be designed by bespoke calculation, by a competent person. For where design sits in the wider rules, see our guide to the Work at Height Regulations.

Which scaffolds need one

HSE lists the scaffolds that typically need a bespoke design. Among them:

• shoring scaffolds, whether dead, raking or flying
• cantilevered scaffolds
• complex loading bays
• temporary roofs and temporary buildings
• façade retention
• free-standing scaffolds
• bridge scaffolds
• suspended and slung scaffolds
• anything outside the manufacturer's guidance or TG20:21 compliance

If you've worked on the tools, you'll recognise these as the jobs where somebody turns up with a drawing. Our guide to the types of scaffolding covers what most of them look like.

What the job involves

The core of it is turning a site problem into a scaffold that can be built and will stand:

• Calculations. Checking loads, ties, bracing and foundations where the standard solutions run out. NASC publishes a TG20:21 Design Guide for exactly that territory, aimed at competent, suitably qualified scaffold designers.
• Drawings and design information. What the crew builds from, and what has to stay on site. The regulations say a copy of the plan for assembly, use and dismantling must be kept available for anyone putting up, using, altering or taking down the scaffold, until it comes down.
• Working with the site. A scaffold is temporary works, and on bigger jobs a Temporary Works Coordinator manages the process, often following BS 5975. HSE notes there's no legal requirement to use that job title or process, but calls BS 5975 the industry consensus on good practice.

HSE also makes the point that temporary works are sensitive to how they're used and easily affected by other work nearby, which is why a temporary works designer needs temporary works training and experience. Getting the sums right is half of it. Knowing what happens to them on a live site is the other half.

How to become one

The routes in are the ones into structural and civil engineering. The National Careers Service lists:

• A degree in structural, civil and structural, or architectural engineering.
• The Civil Engineer Level 6 Degree Apprenticeship, earning while you study.
• Working up from technician. Start as a civil engineering technician, for example through a Level 3 Civil Engineering Technician apprenticeship or an HNC in Civil Engineering, then study for a degree while you work.

Professional registration comes with experience: technicians can work towards EngTech status with the Institution of Civil Engineers, and structural engineers towards membership of the Institution of Structural Engineers.

If you're a scaffolder eyeing the office, the technician route is the realistic one, and you'd bring something plenty of graduates don't: you know how a scaffold actually goes up, and what a drawing looks like from the wrong end of a tube.

What's on offer

On 25 September 2026 there were five scaffold design roles live on ScaffJobs, all in and around London. Three were with one contractor near Tower Bridge, running from a graduate role on a two-year structured programme to a senior role asking for five or more years' scaffold design experience. The other two were design engineer roles in London and Hertfordshire. None of the five published a salary.

The nearest official pay figures are the National Careers Service's: structural engineers from around £24,000 starting out to £55,000 experienced, and civil engineering technicians from £26,000 to £42,000, both on roughly 37 to 42 hours a week.
