placed. These criteria would vary depending on the soil conditions and the size of the
<br />project. The location and frequency of testing would be at the discretion of the
<br />geotechnical consultant.
<br />Contractots Responsibility
<br />All clearing, site preparation, and earthwork performed on the project should be conducted
<br />by the contractor, with observation by a geotechnical consultant, and staged approval by
<br />the governing agencies, as applicable. It is the contractor's responsibility to prepare the
<br />ground surface to receive the fill, to the satisfaction of the soil engineer, and to place,
<br />spread, moisture condition, mix, and compact the fill in accordance with the
<br />recommendations of the soil engineer. The contractor should also remove all non-earth
<br />material considered unsatisfactory by the soil engineer.
<br />It is the sole responsibility of the contractor to provide adequate equipment and methods
<br />to accomplish the earthwork in accordance with applicable grading guidelines, codes or
<br />agency ordinances, and approved grading plans. Sufficient watering apparatus and
<br />compaction equipment should be provided by the contractor with due consideration for the
<br />fill material, rate of placement, and climatic conditions. If, in the opinion of the
<br />geotechnical consultant, unsatisfactory conditions such as questionable weather,
<br />excessive oversized rock or deleterious material, insufficient support equipment, etc., are
<br />resulting in a quality of work that is not acceptable, the consultant will inform the
<br />contractor, and the contractor is expected to rectify the conditions, and if necessary, stop
<br />work until conditions are satisfactory.
<br />During construction, the contractor shall properly grade all surfaces to maintain good
<br />drainage and prevent ponding of water. The contractor shall take remedial measures to
<br />control surface water and to prevent erosion of graded areas until such time as permanent
<br />drainage and erosion control measures have been installed.
<br />SITE PREPARATION
<br />All major vegetation, including brush, trees, thick grasses, organic debris, and other
<br />deleterious material, should be removed and disposed of off-site. These removals must
<br />be concluded prior to placing fill. In-place existing fill, soil, alluvium, colluvium, or rock
<br />materials, determined by the soil engineer or engineering geologist as being unsuitable,
<br />should be removed prior to any fill placement. Depending upon the soil conditions, these
<br />materials may be reused as compacted fills. Any materials incorporated as part of the
<br />compacted fills should be approved by the soil engineer.
<br />Any underground structures such as cesspools, cisterns, mining shafts, tunnels, septic
<br />tanks, wells, pipelines, or other structures not located prior to grading, are to be removed
<br />or treated in a manner recommended by the soil engineer. Soft, dry, spongy, highly
<br />fractured, or otherwise unsuitable ground, extending to such a depth that surface
