Temporary Works Technical Awarenss (TWTAC) Module Two – Below ground temporary works

In house training only - please call for cost – 1 day course

This module is available either as separate individual day, or combined with Module one. They can be attended either before or after any TWCTC or TWSTC courses.

The modules are complimentary to both the accredited CTS Two Day “Temporary Works Co-ordinator” (TWCTC) course (leading to the Cskills examination), and the TWSTC training courses, and will provide the technical content lacking in the procedural courses.

They are aimed at giving an awareness of temporary works and will not involve structural calculations. Extensive handouts will be issued to reduce note taking, and the course is well illustrated. Case studies and simple tutorials are included in each of the modules.

BS 5975 requires that every organisation involved with temporary works has a Designated Individual (DI) whose responsibility is to ensure the management of their own and any sub-contractor’s temporary works. Delegate certificates attending these modules will provide the DI with the assurance that the individuals are up-to-date and competent in the latest technical aspects of temporary works.

Suitable for

The modules are aimed to give all members of the construction process an awareness of the latest advances in the subjects, together with a refreshing update on the basic principles. It is of benefit to those experienced trades-based supervisors, foremen, appointed and trainee temporary works co-ordinators, appointed and trainee temporary works supervisors, graduates, planners, lecturers, site engineers, health and safety advisors and others related to the procurement, design, checking, inspection and approval of temporary works.

Content – Module TWO

This one day course, module two, although intended to follow module one, can be taken separately. Module two is intended to give guidance on the latest requirements for Temporary Works and the procedural control of below ground temporary works to the new BS 5975:2008+A1:2011 and other relevant publications such as CIRIA Report 97. It will also update delegates on today’s use of below ground temporary works in building and civil engineering. Subjects will include understanding soils, slopes, battered excavations, timber in excavations, shallow supported trenches, larger excavations and framing to excavations, working platforms for tracked plant, thrust blocks and pressure testing of pipelines, the use of cranes and lorry loaders, edge protection and access to excavations, sequencing excavation works, controlling water in excavations, surcharging excavations, undermining and underpinning, different types of tower crane foundations, design construction and maintenance of working platforms for tracked plant.

Delegates on Module 2 will be introduced to the following:

  • Understanding the differences between soils and methods of investigation
  • Risk assessing trenches and excavations
  • Trenches and excavations – general considerations
  • Simple sizing of trench shoring to CIRIA 97 methodology
  • Working in and around trenches and excavations
  • Inspection of trenches and excavations
  • Different techniques and equipment for carrying out trenching and excavations
  • Controlling groundwater and surface run-off
  • Mobile crane outrigger pads and other plant used for lifting
