A one day training course focussing on temporary works below ground. It is complemented by a similar training course focussing on works above ground.

The course encourages the exchange of experience by means of delegate comments and questions, group discussion and team exercises. Sessions include types of earth supports and working with earth and water pressures.

Check out the companion course Temporary Works Design (Above Ground).


Temporary Works is a particular source of risk on site, both from a safety and commercial point of view.  Following a series of collapses in the 1970’s, the Bragg report and subsequently BS5975 were produced, to assist designers and users of temporary works.
The industry still recognises today, along with the HSE, the risks associated with temporary works with the competency of the designer being a key point of concern.

Correct design, co-ordination and execution of temporary works is essential to the overall requirement of any project to be completed in accordance with safety, time and budget, health and environmental constraints.

Temporary Works design is different from design of permanent works in several respects, including:

  • Importance of understanding site operations and constraints
  • Need to work closely with the contractor
  • Importance of erection methods and co-ordination

Temporary Works therefore has a code of practice BS5975 that in addition to technical issues also contains a section on procedural control and co-ordination.
