The interest in a recent CPD webinar on the subject we hosted highlighted some of the most common questions and challenges relating to the procedures around the creation and management of Temporary Works Design Briefs. 

In response, we have included the recording of this webinar and compiled a list of the most important or common questions relating to Temporary Works Design Briefs.

What Is A Temporary Works Design Brief?

A mandatory document outlining the scope and requirements for the creation of temporary works designs Once completed it serves as the focus for design decisions, work calculations and drawings and include all data relevant to the design of the temporary works.

Why Is A Design Brief Important?

A TW design brief is required due to the potential dangers of implementing temporary works that are not planned and managed properly.

The origins of the requirement for a temporary works design brief can be traced back to the Bragg Report which was commissioned after a series of fatal temporary works failures in the 1970’s. The requirement is documented by the HSE and BS5975.

The brief is also important as the success of temporary works is dependent on developing the right solution and design to match. The design brief informs the design and helps to ensure the arrival at the best solution.

What should go in a temporary works design brief?

Here are examples of what should be included in a TW design brief

  • Site constraints;
  • Any specific materials and temporary works components you have readily available;
  • Any preference on proprietary requirements that you wish the designer use;
  • Any concept designs you have or thoughts on how to complete the design;
  • Any unusual hazards that you are aware of, for instance, the area floods regularly, or the walls are constructed form an unusual material, etc, etc;
  • Timescales;
  • A clear written description, with sketches if required to demonstrate what is required;
  • Relevant attachments from the project;
  • Relevant soils information;
  • Plant loadings if relevant; 

What shouldn’t be in a design brief?

The following should not be included in a Temporary Works Design Brief

  • Don’t just issue every document you have on the project. Issuing 2 Gb of information to the designer does not ensure the designer has what they need. Take time to prepare what is actually relevant and pass that information on to the designer. 
  • Deadlines that state ASAP, put a date please.

TW Design Brief Procedural Control

The requirement for a design brief is documented in BS5975.

It does not need to be a formal document, but one can be a good guide to ensure that there is sufficient information to allow the design to be completed and checked.

Temporary Works Flowchart representation of the temporary works design brief under BS5975The design brief can be written once the temporary works register process that outlines the required temporary works has begun. They should be completed with suitable time allowed for the creation of the design.

Who is responsible for a TW Design Brief?

The responsibility for the creation and accuracy of TW design briefs on a project rests with the Temporary Works Coordinator (TWC). They do not have to create the brief, but the must ensure that an adequate design brief is provided to the designer and checker.
