I I I agencies. The Engineer will submit initial project design with permit applications at the earliest possible date in a form sufficiently complete to ensure that no substantive changes will occur after the submittal of permit applications. The Engineer will prepare mitigation plans and recommendations for design and construction in compliance with the requirements of the environmental assessment. The Engineer assumes that no significant design changes will occur requiring Edward's Aquifer re-evaluation. In the event that there are changes to this assumption, any additional work to accomplish these tasks will be considered additional services in accordance with Section 1.8. 1.4.2 Review existing schematic design and right-of-way plans and the implications to design, construction, and schedule and provide options and preferred approaches for minimizing impacts including: (a) (b) (c) Review roadway design parameters, including, but not limited to, horizontal alignment, vertical alignment, grades, retaining wall locations and pavement section. Review drainage impacts and design. Review water quality pond location and design and other water quality issues, as related to the Edwards Aquifer. Provide aesthetic options for design. Review proposed Purgatory Creek Bridge for improvements in construction time savings, cost savings, noise reduction and aesthetic improvements. (d) (e) 1.4.3 Perform geotechnical investigations, as required, to form the basis for construction and pavement design recommendations, as well as locate topographic features that may impact construction including: (a) Bridge soil boring holes: i. Purgatory Creek Bridge, estimated at 22 core borings of 40' each. ii. Private Road Bridge, estimated at 2 core borings of 40' each. Retaining wall boring holes: i. Purgatory Creek Bridge approaches, estimated at 12 core borings of 15' each ii. Private Road Bridge approaches, estimated at 8 core borings of 15' each Pavement borings along Wonder World Drive, RM 12 and Craddock Extension: i. 10 core borings of 5' each in easy access areas. ii. 23 shallow hand auger borings along difficult access areas. Lab testing for standard geotechnical classification and strength tests. Geotechnical foundation design criteria for bridge drill shafts, including: i. Allowable end-bearing, if applicable. ii. Allowable side resistance (skin friction). iii. Soil and rock input values for Lateral Load Pile Analysis Software, LPILE. iv. Wincore or Gint boring logs. Geotechnical analyses and recommendations for Mechanically Stabilized Earth ("MSE") retaining walls i. Sliding and overturning ii. Eccentricity iii. Bearing pressure (b) (c) (d) (e) (f) 5
