Scaffolding Design

We offer a comprehensive service of scaffolding engineering design. Our skilled team will develop solutions that will enable you to complete your work efficiently and safely. Whether your project requires a specialised or standard solution, our engineers can design, verify and sign off your scaffold designs.

Our approach to scaffolding:
  • Carry out site visits to discuss your specific needs, the layout of the work site and your safety requirements
  • Design and engineer a solution through calculations and design checks, taking into consideration environment loads and project-specific factors
  • Provide final sign-off of scaffolding, verifying that you have a safe and stable structure for use

We have acquired a great deal of experience from being involved in intricate and challenging projects. Our collaborative approach to scaffolding projects has enabled us to deliver quality and custom-design scaffolding solutions.
