Task Overview. Part of the Substation Scope of Works was the installation of two 1500 kVA transformers, both weighing 5000 kg.

Expedient Engineering Opportunity. Initially functioning as a supervisor to the wider-Substation construction, it was during a routine meeting that I noticed no detailed plan existed to safely install the transformers. The original idea to lower transformers into the Substation had overlooked that the roof and doors to the structure were installed early. (At the time, the Project Manager thought this was a “quick win”.)

I resolved this issue by devising a plan to design and construct a temporary platform in order to safely install the transformers. Realising my very limited Civil Engineering competency, I engaged with an approved subcontractor – Shore Hire – to develop my concept into a legally recognisable design, should something go wrong; I achieved assurance by requesting a design certification from Shore Hire’s engineers.
