What are temporary works?

All major construction sites need temporary works solutions to support the process of constructing the final structure.Temporary works includes erection of site offices, tower cranes, and even temporary structures for use by people who are involved in the construction of permanent structures or infrastructure.The most common types of temporary works are scaffolding for above ground structures and trenching for below ground construction. However, there is a lot more to it than just that. It also includes falsework, which is anything designed to support the permanent structure or infrastructure while under construction.

Why is temporary works engineering necessary?

A construction site is a very dynamic and hazardous environment. In order to safeguard people’s health and safety during construction, one major consideration is designing temporary works to support the structure and/or provide safe access to the structure or excavation. The permanent structure itself could also pose a threat to people’s health and safety during construction.

Who can do temporary works engineering design work?

According to WorkSafe’s Good Practice Guidelines for Excavation Safety, temporary works design should be done by a person who is competent in assessing and managing the risks of excavating to the necessary depth and has a working knowledge of the guideline. This includes Chartered Professional Engineers (CPEng) with experience designing temporary works. The Best Practice Guidelines for Scaffolding in New Zealand also recommends consulting a CPEng when considering high risk hazards associated with erection of scaffolding, e.g. foundation collapse, live and environmental loading, scaffolding exceeding 33 m in height, etc. The Department of Labour Approved Code of Practice for Cranes also requires tower crane foundations to be certified by a CPEng.

Why use BVT for your temporary works engineering?

Apart from our technical knowledge and relevance, at BVT we pride ourselves in our speed and quality of service. Temporary works design is usually outside the typical scope of conventional structural design and often requires a quick turn around, both of which are our specialties. As engineers we have an ethical and statutory requirement to safeguard the health and safety of people which is the ultimate objective of temporary works.
