Description

The health and safety of construction workers should not be put at greater risk from structural failure than other workers. Unfortunately, in Australia and elsewhere, this is not the case. In practice, the frequency of structural failure and the general risk of death is much higher during construction than later. This text may help by providing guidance on procedures, requirements and methods for the design and construction of formwork and falsework to comply with Australian Standards and Work Health and Safety Regulations.

Publication Details

The motivation for creating this Handbook comes from a strong belief that the health and safety of construction workers should not be put at greater risk from structural failure than other workers. Unfortunately, in Australia and elsewhere, this is not the case. In practice, the frequency of structural failure and the general risk of death is much higher during construction than, later, during the service life of the completed permanent structure.
 
In the past, a higher frequency of structural failure may have been tolerated because of an underlying tacit attitude in the design and construction industry that temporary structures, such as formwork, are less important than permanent structures and therefore greater risks are acceptable. However, this is no longer the case.
 
Investigations into the causes of construction failure agree procedural inadequacies enable flaws in the design and/or construction to go undetected. Examples of procedural inadequacies include: communication difficulties and confusion of responsibilities among participants; inadequate briefing of designers; the lack of design drawings; inadequate checking of designs (particularly those containing novel features); unapproved modifications of the initial design; or failure to inspect work prior to loading. Although this research was carried out 30 to 40 years ago, formwork collapse and failure continues to occur all too often and the findings are just as applicable today as then.
 
Implicitly, the higher frequency of structural failure also casts doubt on the competence of those involved in the design and construction of formwork and falsework. This premise is supported by researchers who interviewed those responsible for the design and construction of the majority of falsework in the UK. The researchers found that:
 
(a) At all levels of the industry there is a lack of understanding of the fundamentals and basic principles involved in achieving the stability of falsework;
(b) The contracting sector does not appreciate the implications of the assumptions made by suppliers who design the majority of falsework systems; and
(c) There is a lack of checking and a worrying lack of design expertise.
 
In 2002, the Standing Committee on Structural Safety (SCOSS) in the UK warned that there is a need to carefully consider the means by which falsework is currently procured, designed, constructed and supervised. Furthermore, that judging from the evidence, it is only a matter of time before a serious event occurs. As recently as 2010, SCOSS reported that these concerns remain pertinent.
 
There is no evidence in the literature that “the issues identified in the UK apply to Australia”. However, the frequency of formwork and falsework collapse over recent years support this view.
 
To address the shortcomings identified, SCOSS recommended compiling courses that include elements on procurement, statutory responsibility and managing the supply chain, as well as the technical issues associated with design.
 
To this end, this text may help by providing guidance on procedures, requirements and methods for the design and construction of formwork and falsework to comply with Australian Standards and Work Health and Safety Regulations.
