3.02 SOD HANDLING AND INSTALLATION
A. During delivery, prior to planting, and during the planting of the lawn areas, the sod
panels shall at all times be protected from excessive drying and unnecessary
exposure of the roots to the sun. All sod shall be stacked during construction and
planting so as not to be damaged by sweating or excessive heat and moisture.

laid parallel to the contour of the slope. Immediately following sod laying the lawn
areas shall be rolled with a lawn roller customarily used for such purposes, and then
thoroughly watered.
C. No sod which has been cut for more than 72 hours shall be used unless specifically
authorized by the ENGINEER after ENGINEER'S inspection. Any sod which is not
planted within 24 hours after cutting shall be stacked in an approved manner and
maintained properly moistened.
