Define difference between temporary & permanent responsibilities

[Kiri Robbie]

Can you define the scope difference between temporary and permanent work designer responsibilities (i.e. effects of TW on PW OR temp stability of structures while being constructed)?

[Barnabas Ilko]

This is a very complex question and topic. There is no simple answer for it. In Australia there is no code or procedure that would outline the exact roles and responsibilities. Usually they are set by clients and are outlined in the contract documents via management plans, procedures, references to international codes/practice guidelines etc. Based on the WHS legislation the designer needs to ensure so far is reasonably practicable to minimise the health and safety risks of the workers, stakeholders and the wider public.

When taking a more practical approach, for example temporary stability of structures would be usually up to the temporary works engineer to identify and resolve. In better situations the permanent works engineer might indicate that some critical elements need to be checked or discussed during the temporary state. On some occasions with the modification of permanent works or integration of temporary works into permanent works could be a solution, but it usually requires close collaboration and time spent together between the head contractors and PW, TW engineers. It is very rare when this happens.

When looking at the UK, HSE outlines the legal obligations, CDM the responsibilities and BS5975 provides guidance on the management of temporary works. The combination of these provides a relatively clear indication for each parties what they need to do when, but also involves clients and other stakeholders in the process.
