CONSTRUCTION OF (MISCELLANEOUS INTERSECTIONS, PHASE III, PART A <br />SIGNALIZATION <br />The Board reviewed the following memo dated 7/5/89: <br />TO: James Chandler <br />County Administrator <br />THROUGH: James W. Davis, P. E. ry,06d <br />Public Works Directo <br />FROM: James D. White, P. LJ <br />County Engineer U" <br />SUBJECT: Construction of Miscellaneous Intersections, <br />Phase III, Part A Signalization <br />8th Street at 20th Avenue, 8th Street at 43rd Avenue <br />& 45th Street at 43rd Avenue <br />DATE: July 5, 1989 <br />----------------------------------------------------------------- <br />DESCRIPTION AND CONDITIONS <br />Staff has received, and reviewed, Part A of the final <br />Construction Plans and Specifications, for the subject <br />transportation improvements, from the Engineering Consultant. <br />These improvements are critically needed improvements in the <br />Transportation System. This part consists of a package of three <br />(3) of the overall six (6) projects, packaged and ready for <br />bidding. Right -of -Way Acquisition is complete for these three <br />locations. <br />ALTERNATIVES AND ANALYSIS <br />The following alternatives having been identified: <br />Alternative #1 <br />Call for bids immediately and proceed with construction on these <br />three intersections. Conduct a separate bid for the remaining <br />three intersections. The Engineers estimated probable <br />construction cost is $237,063.05 for these first three work <br />locations. The remaining three intersections are expected to <br />cost slightly more. This alternative will result in some loss of <br />"economy of scale" but will get the first three projects under <br />construction sooner. The remaining three projects are expected <br />to follow in approximately one month. <br />Alternative #2 <br />Hold up these intersection until plans are complete on the <br />remaining three intersections and bid all six sites together. <br />This may gain some economy of scale but will likely delay <br />starting work for at least a month, and perhaps more. <br />Right -of -Way acquisition is not yet complete on the last three <br />intersections. These three intersections are: (12th Street at <br />43rd Avenue, 26th Street at 43rd Avenue, and 41st Street at 43rd <br />Avenue) . <br />Staff recommends approval of Alternate #1. This alternate will <br />get work started soon on three intersections and staff will <br />proceed with all reasonable speed to ready the remaining three <br />intersections for later bidding. <br />FUNDING <br />Funding is proposed from Account #109-141-541-033.19. <br />I'M <br />F <br />
