<p>This Architectural Drawing is AutoCAD 2d drawing of GRADE BEAMS, SUMP PIT DETAILS. A sump is <strong>built based on the risk of water affecting a construction project or finished building</strong>. Water that builds up against a basement wall causes damp and mold to damage the wall and give off odors. Sumps are, therefore, a protection mechanism to keep water away from buildings.
