Task 7-2: 1-580/680 Interchange Ramps--Revise completed <br /> plans and Special Provisions to include upgrading of <br /> existing electroliers to current Caltrans standards at <br /> the following locations: <br /> <br /> o Adjacent to the southbound on-ramp from 1-580 to <br /> 1-680. <br /> <br /> o Adjacent to the northbound off-ramp from 1-680 to <br /> 1-580. <br /> <br />Task 8--Base Conditions <br /> <br />Modify completed base sheets to show existing conditions <br />that reflect the advance construction of grading, certain <br />drainage components, and structural elements. Revise plan, <br />profile, and detail sheets to show the advanced construction <br />as existing conditions. Write special provisions that are <br />coordinated with the previously completed work and the pro- <br />posed remaining construction. <br /> <br />Task 9--Stoneridge Drive Modifications <br /> <br />Revise affected completed plans and specifications and make <br />necessary additions to incorporate a widened street section <br />on the north side of Stoneridge Drive west of the Johnson <br />Drive intersection. <br /> <br /> Task 9-1: Street Widening--Add one lane to the north <br /> side of Stoneridge Drive west of the Johnson Drive in- <br /> tersection. Revise plans, profiles, typical sections, <br /> cross sections, and other affected plans to show the <br /> additional lane. Recompute the related geometric ties <br /> to show the new configuration between the Johnson Drive <br /> intersection and the northbound 1-680 diagonal onramp. <br /> <br /> Task 9-2: Signal Modification--Revise affected com- <br /> pleted plans to show the relocation of the signal pole <br /> in the northwest corner of the Stoneridge Drive-Johnson <br /> Drive intersection. Include revisions and additions to <br /> the pole, mast arm, and electrical system to complete <br /> the relocation. Prepare new plans and special pro- <br /> visions required for the relocation work. <br /> <br /> Task 9-3: Drainage and Utility Modifications--Investi- <br /> gate and analyze the existing drainage facilities and <br /> utilities affected by the street widening. Prepare <br /> plans and special provisions for construction of re- <br /> quired modifications. Review facilities in the field, <br /> obtain field survey data, meet with the CITY, Caltrans, <br /> and affected utility agencies for review and coordina- <br /> tion of the design and construction. <br /> <br /> <br />
