If tests indicate materials do not meet specified requirements, change material and retest.

PART	EXECUTION

STOCKPILING

Stockpile materials on site at locations [indicated] [designated by Architect/Engineer].

Stockpile in sufficient quantities to meet project schedule and requirements.

Separate differing materials with dividers or stockpile apart to prevent mixing.

Direct surface water away from stockpile site so as to prevent erosion or deterioration of materials.

STOCKPILE CLEANUP

Remove stockpile, leave area in a clean and neat condition. Grade site surface to prevent free standing surface water.

****** [OR] ******

[Leave unused materials in a neat, compact stockpile.]

If a borrow area is indicated, leave area in a clean and neat condition. Grade site surface to prevent free standing surface water.
