CHECK TRANSPORTATION FEASIBILITY WHILE WORKING IN AN EXISTING STRUCTURE

The conventional maximum transportation size for an assembly is 12m x 2.5m x 2.5m. This value is not applicable for all the conditions.

TEK1 executed an alteration work inside Canberra airport. Everything that enters an airport must go through the checking / screening area. As per design, the size of assemblies were more than 9m & we were not sure whether these assemblies could be transported into the Airport. So, TEK1 raised a query regarding this. The client agreed to reduce the size of transported assemblies.

Lesson: Whenever a work is carried out inside an existing building, consideration must be given for taking in the assemblies i.e. door/entrance size is mandatory. Since a completed airport terminal is a closed roof structure, cranes cannot be used for erection. Here the erection is done with the help of genie lifts. Weight carrying capacity of the erection machinery must also be taken into consideration.
