As in the attached Job Description
Justification in detail.
To avoid reworks due to Secondary Supports (welding, painting, inspection) and save the associated cost, it is a must to install the E&I secondary supports on the platform deck prior to blasting/painting of the full deck. As per current Practice, secondary supports are installed at a late stage as they are not modelled by Engineering. Hence these are designed, fabricated & installed in Situ by the construction team after major installations have progressed substantially(e.g. primary supports and mechanical pipes/structures, Main Cable Ladder etc) to ensure clash free installation to the extent possible by visualizing the proper route, location, type and dimension.
As an improvement initiative, we decided to model the secondary supports by designers/draftsman similar to primary supports and reflected in related drwgs; however at Management Level it was agreed to handle this task of Constriction Engineering by E&I Yard (pls refer attached Division of Responsibilities between Engg and E&I Yard). On the recently concluded CRPO’s, it is estimated that approx.6M AED over run was caused due to reworks related to Secondary supports, which can be saved on future projects.
