Temporary Works Design - Introduction (BS 5975:2008+A1:2011)


Temporary works (T.W.) are essential to the technical and financial success of construction projects. Proper selection, design and execution of the T.W. is often a key factor in both cost effectiveness and safe implementation of the system adopted.
The newly revised B.S. 5975:2008 + A1:2011 - has been extensively modified to cover the control and supervision of T.W. It is therefore important that design engineers are aware of their responsibilities under the current standards and communicate the relevant information required for successful and safe implementation of their design

Aims & Objectives:

This course aims to enable delegates to design some commonly encountered temporary works, assess the risks associated with a range of commonly encountered T.W. approaches and evaluate how site conditions can affect the loadings encountered.

On completion of this course, delegates will be able to:

  • Appreciate the importance and function of T.W. to overall project objectives.
  • Determine the loading conditions that apply to a range of commonly encountered T.W. systems.
  • Evaluate how site conditions influence T.W. selection and affect the loading that the T.W. has to be able to resist.
  • Be able to design a typical piling mat, sheet piled retaining wall, crane footings.
  • Be able to identify the associated key risk factors associated with conventional T.W. systems
  • Appreciate the control structure for T.W. site operations required by BS 5975 and understand the Design Engineers role in this structure.
  • Avoid many of the common pitfalls found in conventional T.W.
  • Be able to critically evaluate/check aspects of T.W. designs done by others

Course Outline:

  • The role of T.W. in construction projects.
  • The rational behind BS575 - the code of practice for falsework
  • Determining the loads and deflections that the T.W. are required to cater for
  • Assessing the influence of site conditions on T.W. selection and loadings to be carried.
  • Key stability issues for Scaffold, formwork and support systems.
  • Formwork - basic components and design performance.
  • Underpinning - methods and critical issues
  • Piling - types and operational issues
  • Earthworks - excavation, trenching and embankments, effects of ground water and changing conditions
  • Plant associated with temporary works
  • Influence of changes in the site environment and working methods on T.W.
  • Preparing method statements for T.W.
  • Assessing risks in temporary works


Mode of Delivery:

Mode of Delivery:

  • An examination and discussion of key issues, using a Power Point presentation
  • Case studies on method statements for a range of T.W. situations
  • Exercises on basic design for piling mat, sheet piled wall
  • Discussion and review

Benefits of Attending:

  • Be more effective in their roles and duties with respect to T.W. design and control
  • Have an increased ability to detect site factors that may compromise the successful performance of a T.W. design, and know how to react to such changes.
  • Understand the sensitivity of standard T.W. systems to changes that can cause potential failure or collapse, and hence identify key risk and sensitivity factors.


Intended For:

  • Graduate engineers
  • Site Engineers with responsibility for temporary works
  • Designers and checkers of Temporary Works

Pre-Course Requirements:

  • Have an awareness of the function of temporary works in a project
  • Have experience of site operations.
  • Have a familiarity with method statements and risk assessments
  • Complete a pre-course questionnaire
