A Study on Grating Cut-Outs
Grating is used as a flooring material in many industries as well as for drainage and for platforms around vessels
and columns. It is also used as a pit and drain covers where heavy haul vehicle movement is expected. Though design of
grating panels is not considered a high end engineering activity, but proper management of the whole process of grating
engineering, fabrication and installation is crucial to the success of the project.
In one of the recent project engineered by Fluor Daniel India, about 10000 sq. meter of grating was laid. The paper discusses
the various issues that were faced in the entire course related to provisioning of grating, starting from engineering to
installation. These issues pertain to design of gratings with large opening, management of changes in cutouts post issue of
drawings. Standard way to provide supporting arrangements for those new cut-outs in the erected grating panel would
hamper cost baseline and schedule baseline. A fast and economic way to tackle the problem was implemented.
To achieve a rapid and economical solution, the paper presents solutions that were given at site to take care of the huge
number of modification required so as to effectively reduce construction time.
