Common use of Field Exploration Clause in Contracts

Field Exploration. 4.2.1.1. The Professional shall determine the required boring locations on the Project Site. The Professional shall provide a Project Site boring location map to NBU via email prior to start of the field work that shows the exploratory borings within the vicinity of the proposed improvements and along the proposed water main alignments. 4.2.1.2. The Professional shall coordinate with NBU, City of New Braunfels, and Texas 811 regarding underground utilities within the vicinity of the planned boring locations prior to commencement of the field exploration activities. 4.2.1.3. The Professional shall drill exploratory borings for the proposed improvements according to the schedule provided below: 4.2.1.3.1. one (1) boring to a maximum depth of 60 feet below existing grade; 4.2.1.3.2. six (6) borings to a maximum depth of 30 feet below existing grade; 4.2.1.3.3. two (2) borings to a maximum depth of 25 feet below existing grade; and 4.2.1.3.4. four (4) pilot hole borings for the purpose of locating below-grade voids. 4.2.1.4. The borings conducted on the Project Site shall be advanced using standard rotary drilling equipment with continuous-flight augers or rotary wash methods. Subsurface samples shall be collected using 2-inch diameter split-spoon sampler in conjunction with the standard penetration test (“SPT”). Intermittent 3-inch diameter Shelby tube samples shall be collected in between the SPTs. 4.2.1.5. The Professional shall record groundwater observations within the borings at the time of drilling and at the completion of drilling and sampling. 4.2.1.6. The Professional shall backfill borings with auger cuttings upon completion of drilling and sampling. 4.2.1.7. The Professional shall patch borings drilled through pavement with like material (asphalt, concrete) upon completion of backfilling. 4.2.1.8. The Professional shall have personnel experienced in logging borings, directing the drilling, and handling and transporting the samples. The Professional shall provide visual classification of the subsurface stratigraphy in general accordance to the American Society for Testing and Materials (“ASTM”), standard number D2488 and the Unified Soil Classification System (“USCS”) during drilling and sampling.

The Professional shall coordinate with NBU, City of New BraunfelsCoNB, and Texas 811 regarding underground utilities within the vicinity of the planned boring locations prior to commencement of the field exploration activities. 4.2.1.34.3.1.3. The Professional shall drill exploratory borings for the proposed improvements according to the schedule provided below: 4.2.1.3.14.3.1.3.1. one (1) One boring to a maximum depth of 60 twenty (20) feet below existing grade; 4.2.1.3.2. six grade at each of the three (63) Project Sites (FM 306 Pump Station, Newks Pump Station, and County Yard Pump Station) for a total of three (3) borings to a maximum depth of 30 feet below existing grade; 4.2.1.3.3. two (2) borings to a maximum depth of 25 feet below existing grade; and 4.2.1.3.4. four (4) pilot hole borings for the purpose of locating below-grade voidsthis Project. 4.2.1.44.3.1.4. The borings conducted on the each Project Site shall be advanced using standard rotary drilling equipment with continuous-flight augers or rotary wash methods. Subsurface samples shall be collected continuously within the upper ten (10) feet and at 5-foot intervals afterwards using 3-inch diameter Shelby tube samples and a 2-inch diameter split-spoon sampler in conjunction with the standard penetration test (“SPT”). Intermittent 3Rock and rock-inch diameter Shelby tube samples shall like materials, if encountered, will be collected in between cored and/or tested in-situ testing (SPT or the SPTsTexas Cone Penetration Test) at 5-foot intervals. 4.2.1.54.3.1.5. The Professional shall record groundwater observations within the borings at the time of drilling and at the completion of drilling and sampling. 4.2.1.64.3.1.6. The Professional shall backfill borings with auger cuttings upon completion of drilling and sampling. 4.2.1.74.3.1.7. The Professional shall patch borings drilled through pavement with like material (asphalt, concrete) upon completion of backfilling. 4.2.1.84.3.1.8. The Professional shall have personnel experienced in logging borings, directing the drilling, and handling and transporting the samples. The Professional shall provide visual classification of the subsurface stratigraphy in general accordance to the American Society for Testing and Materials (“ASTM”), standard number D2488 and the Unified Soil Classification System (“USCS”) during drilling and sampling.
