New Zealand Institute of Highway Technology - NZIHT

Overview

Competent supervision skills are essential in producing a final product that meets all design and specification requirements.  High levels of productivity can be achieved through the effective and efficient use construction techniques, gained through a combination of knowledge, good planning and organisation skills which best utilises the resources available to the supervisor.

The drainage construction supervisor is responsible for the proper setting out, excavation, pipe laying and back filling of drainage trenches. Suitable compaction techniques are important if rework associated with settlement is to be avoided.

The supervisor should have a good knowledge of various types of pipes, jointing systems and a good knowledge of materials suitable for both bedding and backfilling.

The course attempts to highlight the aspects of construction that will have a significant effect on the quality of the finished product. In addition, Health and Safety issues are addressed as appropriate.
