J-U-B Agreement for Professional Services Attachment 1A – Detailed Scope of Work Page 4 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. 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, ¾-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. Analyze the geotechnical testing data to determine the most cost-effective form of new construction. Analyze the performance and stability of existing asphalt section. Rehabilitation methods may include full depth reconstruction in designated select locations, pavement removal and replacement, or pavement overlay depending on test results. Hold a meeting with the CLIENT and FAA at the Airport to present findings of the Geotechnical Testing and analysis of existing pavement. Determine rehabilitation/reconstruction method best suited for the pavement surfaces. Define critical aircraft for the pavement design of the project and develop pavement design section. Pavement design criteria shall be in accordance with the FAA Advisory Circular (AC) 150/5320 - 6G. This will include calculating and reporting the Airport Pavement Strength - PCR. Perform analysis of existing geometric layout of Taxiway/Runway fil lets and radii to determine compliance with current FAA AC requirements. Present findings to CLIENT and FAA for review and comments. Review existing storm water drainage within the project boundary. Evaluate existing drainage patterns and systems. J -U-B shall conduct a required analysis for the design of drainage improvements associated with the project in accordance with the FAA AC 150/5320-5D, Surface Drainage Design. Any necessary drainage improvements will be sized to accommodate local drainage standards. This drainage effort is intended to integrate w ith previously established drainage designs (specifically the Parallel Taxiway).
