Scaffolding is a critical part of almost every construction project in the UK from small residential renovations to large commercial builds. But behind every safe scaffold you see on-site lies a carefully prepared scaffolding drawing. These drawings act as a detailed blueprint, ensuring the structure is safe, compliant, and efficient.
In this in-depth guide, we’ll break down the step-by-step process of creating a scaffolding drawing, highlight UK regulations and safety standards, and answer the most common questions people search on Google about scaffold design.
If you’re a contractor, site manager, or client looking to understand the process, this article will show you exactly why working with professional scaffold designers is essential.
Why Scaffolding Drawings Are Essential
Before we dive into the step-by-step process, let’s understand why scaffolding drawings matter
- Legal requirement: Under the Work at Height Regulations 2005, all scaffolds (except simple, standard structures) require a formal design.
- TG20:21 compliance: The NASC’s TG20:21 guidance outlines rules for tube and fitting scaffolds in the UK. If a scaffold falls outside “compliant scaffolds,” a bespoke design is required.
- Safety assurance: A good drawing accounts for load capacity, tie patterns, bracing, and environmental factors like wind and snow.
- Efficiency: By planning in advance, scaffolds are built quicker, with fewer modifications on-site.
In short, scaffolding design is the difference between a safe, compliant structure and a risky, non-compliant one.
Step 1: Conducting a Site Survey
Every scaffold design starts with a thorough site survey.
What’s involved in a site survey?
- Measuring ground conditions (soil type, ground bearing capacity).
- Identifying access restrictions such as narrow streets or overhead obstructions.
- Checking for existing structures that may need to be tied into.
- Assessing public protection requirements (pedestrian walkways, traffic management).
- Recording dimensions of the building or structure that scaffolding will serve.
Skipping this step is one of the biggest mistakes contractors make. Without a survey, it’s impossible to create an accurate scaffolding drawing.
Professional scaffold designers will always conduct or request a detailed survey before drafting begins.
Step 2: Defining the Scaffold Requirements
Once the survey is complete, the next step is to establish what the scaffold needs to achieve.
Questions to ask:
- Is the scaffold for access, support, or protection?
- What height and width are required?
- Will the scaffold need a temporary roof design?
- How many workers and how much material will it need to support at once?
- Is it a short-term or long-term structure?
Defining these requirements allows scaffold designers to choose the right system (tube & fitting, system scaffold, or hybrid).
Step 3: Structural Calculations
The backbone of any scaffold design is accurate calculations. These ensure the scaffold can withstand all live loads (workers, tools, materials), dead loads (scaffold’s own weight), and environmental loads (wind, rain, snow).
Key considerations in calculations:
- Load classes as defined in BS EN 12811.
- Wind loading (critical for scaffold temporary roof design).
- Tie patterns and anchor strength.
- Foundation pressures on soil or slabs.
These calculations are then integrated into the scaffolding drawing to demonstrate compliance.
Working with a scaffold design company guarantees that all structural calculations are documented for inspectors, insurers, and clients.
Step 4: Drafting the Scaffolding Drawing
With data collected and calculations completed, the next stage is drafting the actual scaffolding drawing.
What’s included in a scaffolding drawing?
- Plan views (overhead view of layout).
- Elevations (side views showing dimensions and tie positions).
- Sections (cut-throughs of complex areas).
- Notes and specifications (loading bays, guardrails, toe boards, etc.).
- Material list (tube lengths, couplers, boards, sheeting).
Modern scaffolding designers often use CAD or BIM software to produce detailed, precise drawings that can be shared digitally.

Step 5: Safety and Compliance Review
Once drafted, the drawing must be reviewed against UK regulations:
- Does it comply with TG20:21?
- Are all Work at Height obligations met?
- Are access and egress points clearly designed?
- Have public safety measures (hoardings, fans, covered walkways) been included?
- Does the scaffold meet fire escape requirements if relevant?
This step ensures that the scaffold is not just structurally sound but also legally compliant.
Step 6: Client Approval
The next stage is client approval. The scaffold design company will send the drawings and calculations to the client or contractor for review.
Clients often look for:
- Clear identification of scaffold purpose.
- Easy-to-read layouts.
- Assurance that health and safety requirements are covered.
If adjustments are needed, revisions are made before final approval.
Step 7: Issuing Final Scaffolding Drawings
Once approved, the final set of scaffolding drawings is issued for on-site use. These will be provided to:
- Scaffold erectors.
- Site managers.
- Health and safety officers.
- Inspectors.
The drawings act as the official instruction manual for building the scaffold safely and correctly.
Step 8: On-Site Implementation and Revisions
Even the best designs may require updates once construction starts. Changes in site conditions, weather, or project scope may require revisions.
Best practice:
- Always update drawings when changes are made.
- Document revisions to stay compliant.
- Ensure scaffolding designers are available for consultation during build.
Step 9: Scaffold Temporary Roof Design (When Required)
Temporary roofs are one of the most challenging parts of scaffold design. They protect worksites from weather but also introduce complex wind loads.
Key elements of roof design:
- Secure bracing and anchoring.
- Use of wind-rated sheeting.
- Structural checks for uplift forces.
Due to complexity, only experienced scaffolding designers should attempt scaffold temporary roof design.

Step 10: Inspections and Ongoing Compliance
Even after a scaffold is erected, compliance doesn’t end. UK law requires:
- Inspections before first use.
- Inspections every 7 days.
- Inspections after bad weather or alterations.
Scaffolding drawings are kept on file to prove the scaffold was erected in line with design.
Common Scaffolding Design Questions
What is a scaffolding drawing?
It’s a detailed technical plan showing how a scaffold should be built, including dimensions, load calculations, tie patterns, and safety notes.
Do I need a scaffold design for small projects?
Yes, unless the scaffold is a standard TG20:21-compliant design. Most projects require a formal drawing.
Who creates scaffolding drawings?
Competent scaffold designers or engineers trained in scaffold design.
How long does it take to get a scaffold drawing?
Simple projects may take 1 to 2 days, while complex designs (like those with temporary roofs) can take longer.
How much does scaffold design cost?
It depends on complexity, height, and safety requirements. Contact a scaffold design company for a tailored quote.
Why Work With a Professional Scaffold Design Company?
Some contractors try to cut corners with generic drawings or internal drafts. But in the UK, this is both risky and non-compliant.
A professional scaffold design company offers:
- Full TG20:21 and Work at Height compliance.
- Expert scaffolding designers trained in safety and structural engineering.
- Precise scaffolding drawings backed by calculations.
- Support for complex needs like scaffold temporary roof design.
At Fox Scaffold Design, we specialise in providing safe, compliant, and cost-effective solutions tailored to your project.
Conclusion: From Drawing to Safe Scaffold
Creating a scaffolding drawing is not just a paperwork exercise it’s a vital step in ensuring safety, compliance, and efficiency on UK construction sites.
By following a structured process from site survey to structural calculations, drafting, approvals, and inspections you avoid risks and keep your project on track.
And by working with experienced scaffold designers, you ensure your scaffold isn’t just fit for purpose but fully compliant with UK law.
