Corporate knowledgebase for OHS planning in construction
Construction accidents cause many human tragedies, demotivate construction workers, disrupt construction processes, delay progress and adversely affect the cost, productivity and reputation of the constructor (Kartam 1997). Preproject and pre-task OHS planning is among the critical measures required to achieve a zero accident target (Saurin et al. 2004). The ability to identify health and safety hazards as early as possible and implement adequate controls is vital to a project of any size and scale (Cheung et al. 2004). The deployment of effective OHS planning and control techniques on construction sites to prevent accidents can therefore have signiﬁcant human, social and ﬁnancial impacts. Moreover, OHS planning often appears as a core requirement in OHS regulations and standards. For instance, OHS regulation 2001 of New South Wales, Australia, states that: ‘The principal contractor for the construction work must ensure that a site speciﬁc OHS plan is prepared for each place of work at which the construction work is to be carried out before the work commences’ (WorkCover NSW 2001a).
