Specifications include, but are not limited to: 1. BORINGS The location and depth of the proposed borings proposed by the Engineer shall be submitted by the Engineer for District approval. Quantity and locations of proposed borings must be adequate to satisfy requirements of any and all state and federal agencies, laws and regulations governing K-12 school construction. If the Engineer finds it necessary to change the location or depth of any of these proposed borings, the Architect of Record shall be notified, and a new location or depth shall be agreed upon between the Architect and the Engineer. If unusual conditions are encountered, including but not limited to unanticipated materials which cannot be penetrated by standard sampling equipment, the Engineer shall immediately consult with the Architect of Record for the Project. The Engineer shall advise the Architect of Record and District as to any further exploration and testing required to obtain information that the Engineer requires for a professional interpretation of subsoil conditions at the building site and shall perform such additional work as authorized by the District after consultation with the Architect of Record. The extent of exploration undertaken shall be consistent with the scope of the Project as indicated by the information given above and by any drawings attached hereto. Unless otherwise stipulated, drilling and sampling will be performed in accordance with current applicable ASTM (American Society of Testing and Materials) standards and other standards, including, but not limited to, ASTM standards D1586, D1587 and D2113. Field logs and boring maps shall be prepared either by the Engineer or by an experienced soils technician acting under the supervision of the Engineer. All samples shall be preserved by the Engineer until all foundations are complete and accepted by DSA. 2. DRILLING AND SAMPLING METHODS AND PROTECTION OF PROPERTY The Engineer shall contact the District and all utility companies for information regarding buried utilities and structures and shall take all reasonable precautions to prevent damage to property both visible and concealed. All drilling and digging locations shall be coordinated with verified underground utility locations to avoid damaging existing infrastructure and/or utilities. Engineer is responsible for any and all impacts, damages, and delays caused by boring operations that damage existing infrastructure and/or utilities. Engineer shall reasonably restore the site to the condition existing prior to the Engineer’s entry and work. Such restoration shall include, but not be limited to, backfilling of borings, patching of slabs and pavements, and repair of lawns and plantings. Each boring should be temporarily plugged, pending additional groundwater readings. At the completion of the groundwater readings, the borings shall be permanently plugged, including patching of slabs and pavements. Field logs and boring maps shall be prepared either by the Engineer or by an experienced soils technician acting under the supervision of the Engineer. All samples shall be preserved by the Engineer until all foundations are complete and accepted by DSA.
