TASK ORDER 2025-01 HANGAR TAXILANE COMPLEX PHASE 1 DESIGN AI P-3-53-0026-024-2025 The collected data shall be provided on a compact disk to the Engineer with the following information: point number, description, northing, easting, and elevation along with paper copies of any pertinent field notes. No map or drawing will be required. 3. Administer design Geotechnical Subconsultant contract and coordinate delivery of work product. Provide quality control review of work products. This will include one (1) on -site meeting with geotechnical Subconsultant to review project location and safety. The geotechnical laboratory work will be performed utilizing the services of a Subconsultant. The general scope of the geotechnical work will be the following: Administer three (3) cores/bore logs on the proposed taxilane alignment to a depth of 6-feet or refusal. The geotechnical engineer shall immediately patch all pavement core holes with an approved asphalt cold mix or similar product. Data shall be collected on the soil type, existing asphalt condition, and depths and categorized according to the Unified Soil Classification System (USCS) including Moisture Content, Atterberg Limits, Grain Size Distribution. A sieve analysis shall be performed on both the base course and subbase for each core/bore location. The sieve analysis for base course should include the following classifications: percentage by weight passing sieves of 1-inch, 3/4-inch, No. 4, No. 40, No. 200, and 0.02 mm. The sieve analysis for subbase course should include the following classifications: percentage by weight passing sieves of 3-inch, No. 10, No. 40, No. 200, and 0.02 mm. Ground water depth shall be recorded if encountered. Three California Bearing Ratio (CBR) test shall be performed on the bore log samples at a depth of 24-inches which is the anticipated depth of subgrade. The geotechnical engineer shall coordinate with the Engineer to determine exact core/bore log locations. The geotechnical work shall be conducted in accordance to FAA AC 150/5370-2G safety guidelines. The geotechnical engineer shall be responsible for a utility locate prior to work. It should be anticipated that the cores/bore logs shall be taken during nighttime hours. The geotechnical firm will need to coordinate with the Airport Manager and the Engineer personal for closure time and date. The geotechnical firm shall submit 3 copies of the final geotechnical report including all required information as mentioned above to the Engineer within three weeks upon finishing field work. The firm shall submit a draft copy for review prior to finalizing the report and its findings. This line item shall include the coordination and contracting with Subconsultant. The Subconsultant fees shall be addressed in the Expenses-Subconsultant Section. \\jub.com\Central\Clients\WA\KittitasCou my\Projects\45-25- 022_BowersFie ld_H angarTxln_PhaselDsgn\ProjMgmt\Agreements\Old\TO 2025_01_RevSept2025.docx 5
