skill set to develop site-grading plans that meet the standards of care
expected of design professionals.
what does the student need to know aBout GradinG?
1.
Be familiar with drafting conventions and the use of architectural and engi-
neering scales.
2.
Be able to read topographic maps and be able to identify landform features
such as hills, valleys, steep and not-so-steep terrain, and drainage patterns.
Also, the student should be able to determine elevations of any point or fea-
ture from a topographic map.
3.
Be able to visualize three-dimensional landscape from contours given on a
topographic map or map prepared by a land surveyor.
4.
Be able to create a land surface, path, or built program feature that has a
prescribed or intentional slope.
5.
Be able to manipulate (change or modify) contours in order to create desired
landforms and sloping surfaces. Also, the student must be able to manipu-
late contours so as to direct the flow of surface water in a desired direction,
such as away from the entrance of a building.
6.
Be able to assign spot elevations in plan and on sections.
7.
Be able to calculate the volume of earth moved within a project site and
determine the volume of earth or other soil or rock material that needs to be
transported to or off the project site.
8.
Be able to prepare (draw) grading plans following graphic conventions so
that the contractor knows what to build. The grading plans must be of suf-
ficient detail, and of course accuracy, that the contractor can prepare with
confidence a cost estimate for doing the required work as depicted in the
drawings and other contract documents.
9.
Be knowledgeable about and understand various and pertinent design
standards and legal requirements associated with grading. This knowledge
base may include functional design requirements of minimum and maxi-
mum slope for various program elements such as recreation fields, parking
and circulation, and handicap access (standards for persons with ambulatory
and other physical disabilities).
