Common use of GEOTECHNICAL DATA REPORT Clause in Contracts

GEOTECHNICAL DATA REPORT. The Professional shall conduct a geotechnical investigation to complete a GDR for the Project as described below. a) The Professional shall select appropriate locations for exploratory borings along the proposed discharge line route. b) In accordance with Section 12(I) of this Agreement and pursuant to the requirements defined in Section 10(A)(ix) of this Agreement, the Professional shall seek written permission from NBU, to subcontract with a drilling contractor to drill five (5) exploratory borings along the proposed discharge line route each to a depth of fifteen (15) feet below existing grade. The borings shall be advanced using standard rotary drilling equipment with continuous-flight augers (solid or hollow stem) or rotary wash methods. Subsurface samples shall be collected using 3-inch diameter Shelby tubes for cohesive soils and a 2- inch diameter split-spoon sampler in conjunction with the standard penetration test (“SPT”) for intermediate and non-cohesive soils. Rock and rock-like materials shall be cored using an NX core barrel and/or tested in situ using the Texas cone penetration test or the SPT, as appropriate for the material. The borings shall be backfilled with auger cuttings upon completion of drilling and sampling. c) The Professional shall record the groundwater observations within the borings at the time of drilling and at the completion of drilling and sampling. d) The Professional shall select samples for laboratory testing, assign tests, and review the test results. e) The Professional shall perform a geotechnical analysis and prepare a GDR documenting the analysis, which will be delivered in accordance with Task 3, Section. The GDR shall include the following: i) a summary of the field and laboratory sampling and testing program; ii) boring logs and laboratory testing results; iii) a review of general site conditions including descriptions of the site, the subsurface stratigraphy, groundwater conditions, and the presence and condition of fill materials, if encountered; iv) trenchless water main construction feasibility and recommendations of auger boring and horizontal directional drilling; v) general discussion of expected construction related issues; and vi) earthwork related recommendations for use during development of plans and specifications.

GEOTECHNICAL DATA REPORT. The Professional shall conduct a geotechnical investigation to complete a GDR Geotechnical Data Report (“GDR”) for the Project as described belowherein. a) 4.2.1. Field Exploration shall be conducted as described herein. 4.2.1.1. The Professional shall select appropriate determine the required boring locations for on the Project Site. The Professional shall provide a Project Site boring location map that shows the exploratory borings within the vicinity of the proposed improvements and along the proposed discharge line routewater main alignments. b) In accordance with Section 12(I) of this Agreement and pursuant to the requirements defined in Section 10(A)(ix) of this Agreement, the 4.2.1.2. The Professional shall seek written permission from coordinate with NBU, CoNB, and Texas 811 regarding underground utilities within the vicinity of the planned boring locations prior to subcontract with a drilling contractor to commencement of the field exploration activities. 4.2.1.3. The Professional shall drill five two (52) exploratory borings along the proposed discharge line route each to a maximum depth of fifteen (15) 20 feet below existing gradegrade for the proposed improvements. 4.2.1.4. The borings conducted on the Project Site shall be advanced using standard rotary drilling equipment with continuous-flight augers (solid or hollow stem) or rotary wash methods. Subsurface samples shall be collected using 32-inch diameter Shelby tubes for cohesive soils and a 2- inch diameter split-spoon sampler in conjunction with the standard penetration test (“SPT”) for intermediate and non). Intermittent 3-cohesive soils. Rock and rock-like materials inch diameter Shelby tube samples shall be cored using an NX core barrel and/or tested collected in situ using between the Texas cone penetration test or the SPT, as appropriate for the material. The borings shall be backfilled with auger cuttings upon completion of drilling and samplingSPTs. c) 4.2.1.5. The Professional shall record the groundwater observations within the borings at the time of drilling and at the completion of drilling and sampling. d) 4.2.1.6. The Professional shall select samples for laboratory testing, assign tests, backfill borings with auger cuttings upon completion of drilling and review the test resultssampling. e) 4.2.1.7. The Professional shall perform a geotechnical analysis 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 prepare a GDR documenting handling and transporting the analysissamples. The Professional shall provide visual classification of the subsurface stratigraphy, which will be delivered in general accordance with Task 3the American Society for Testing and Materials, Sectionstandard number D2488 and the Unified Soil Classification System during drilling and sampling. 4.2.2. The GDR Professional shall provide laboratory testing to include the following: i) 4.2.2.1. testing on samples obtained from the borings to determine soil classification and pertinent engineering properties of the subsurface materials; and 4.2.2.2. laboratory tests assigned for the specific subsurface materials encountered during exploration on the Project Site, but which are expected to include the following number and type of tests: 4.2.2.2.1. Atterberg limits tests (up to a 6 tests); 4.2.2.2.2. Percent Passing the #200 Sieve (up to 6 tests); 4.2.2.2.3. Moisture content tests (up to 14 tests); and 4.2.2.2.4. Unconfined compressive strength tests (with unit weights; up to 2 tests). 4.2.3. The Professional shall prepare a GDR that includes the following information and recommendations, as applicable: 4.2.3.1. a summary of the field and laboratory sampling and testing program; ii) 4.2.3.2. boring logs and laboratory testing results; iii) 4.2.3.3. a review of general site conditions including descriptions of the site, the subsurface stratigraphy, groundwater conditions, and the presence and condition of fill materials, if encountered; iv) 4.2.3.4. trenchless water main construction feasibility and recommendations of auger boring and and/or horizontal directional drilling; v) 4.2.3.5. general discussion of expected construction related issues; and vi) 4.2.3.6. earthwork related recommendations for use during development of plans and specifications. 4.2.4. The Professional shall provide the final GDR electronically as a 100% design deliverable with the specifications.
