What Are Temporary Works Design Checks?
Temporary works design checks are the documented verification that temporary structures used during construction — including formwork, falsework, propping, shoring, cofferdams, and temporary access structures — have been properly designed, checked, and approved before erection. The checks cover the design calculations, drawings, materials, erection sequence, and loading assumptions. A designated Temporary Works Coordinator (TWC) oversees the process, ensuring that designs are checked by an independent competent person before the temporary works are built and loaded.
Why Temporary Works Design Checks Matter
Temporary works failures are among the most catastrophic incidents in construction — collapses can cause multiple fatalities, as seen in several high-profile UK incidents. The CDM Regulations require that all temporary works are properly designed and managed, and industry standard BS 5975 sets out the detailed procedures. HSE investigations following temporary works failures consistently focus on whether design checks were properly documented and whether an independent check was carried out. Missing or inadequate design check records indicate a systemic failure in safety management.

Frequently Asked Questions — Temporary Works Design Checks
What is the role of a Temporary Works Coordinator?
The Temporary Works Coordinator (TWC) manages the temporary works process on site. Their duties include maintaining the temporary works register, ensuring designs are produced and independently checked before erection, overseeing the erection and loading of temporary works, and authorising striking (removal). The TWC does not need to be the designer but must be competent to manage the process.
What is an independent design check and when is it required?
An independent design check is a review of the temporary works design by a competent person who was not involved in the original design. It verifies that the design is adequate for the intended loads and conditions. BS 5975 requires independent checking for all temporary works categories, with the level of check proportionate to the risk and complexity.
What records should be kept for temporary works?
Records should include the temporary works register listing all temporary works on site, design calculations and drawings, the independent design check certificate, the permit to load (confirming erection matches the design), inspection records during use, and the permit to strike (authorising removal). All records should be retained for the duration of the project.
