Grading

A concept of design grading is essential in developing the physical form o f the site.Positive drainage, il most important concept in grading, allows stornl water runoff to i'l(iw away fronl the structures and activity areas. When water allows away  structures ~ d towards drainage channels, flooding is presented. Studying existing a ~ proposed topography in inodcl ti)rm will aid in relating buildings or activities to the 1:111~1.The grading plan is the n~ost inlportant study in the technical development of tlie site pli1111, The major consideration in a grading plan is to set trial or preli nlinary spot evaluations in order lo achieve a 1,ositive drainage pattern. Before tlie grading study begins, the project's layout has already heen drawn on the topographic ~ n i ~ This,p . study may lead to clianges in placement of h e building or circulation. The grading methods and equipment will be discussed in detail .
