Temporary works play a crucial role in the safe and efficient delivery of construction projects.

Having worked in the temporary works sector for over 20years, the industry has developed and grown and there are now some excellent temporary works design companies in the UK. A large proportion of these temporary works design solutions will rely on some interaction with the existing ground. The associated risk will mean they will either fall into CAT 2 or CAT 3 requiring an independent check.

Where resources and expertise are available in-house a CAT 2 check can be undertaken by the same organisation undertaking the design. A CAT 3 check will always require a third-party independent check to ensure design assurance. DesignCheckStudio can provide design assurance though both CAT 2 and CAT 3 checks.

Typical temporary works examples are:

• Site set up including cabin foundations, haul roads, hoardings, working platforms etc
• Temporary excavation support
• Sheet pile walls and cofferdams
• Piling platforms
• Crane outrigger stability
• Temporary bridges and foundations
• Slope stability assessments
• Scaffold foundations

Permanent works by their nature are complex engineering undertakings which inevitably will have some reliance on the existing ground.

Permanent works within regulated industries such as highways, railways, defence, energy etc will be undertaken under documented design assurance standards. With over 35years experience working within these sectors as both designer and checker DesignCheckStudio can provide the necessary design assurance though both CAT 2 and CAT 3 checks.

Typical permanent works examples are:

• Piled foundations
• Spread foundations
• Embedded retaining walls
• All forms of retaining wall
• Reinforced soil embankments
• Reinforced soil walls
• Embankment and cutting stability analysis
• Settlement assessments

• Reinforced concrete
• Structural steel
• Timber
• Hydraulics & Open Channel Flow
• 3D ground modelling
• Cut & Fill analysis
• 3D visualisations
