CASE # 3 <br /> <br />CONSIDER CHANGE ORDER FOR IMPROVEMENT PROJECT 05-22 <br />RAMSEY TOWN CENTER PHASE 2 SEGMENT 1 <br /> By: Steven Jankowski, City Engineer <br /> <br />Background: <br /> <br />This project includes the construction of Civic Center Drive between Zeolite and <br />Sapphire Streets. One element of this street includes a "bump out" in the street section to <br />accommodate the bus loading zone in fi.ont of the municipal parking structure. Concrete <br />pavement is required through the area that busses will be braking and accelerating to <br />prevent rutting and shoving that would be anticipated if bituminous pavement were <br />utilized. The plans called for a 10 foot wide concrete bus parking section on the south <br />side of the street, but made an accommodation for only a five foot segment on the north <br />side. If constructed in this manner only the right side on the bus wheels would be braking <br />on concrete pavement. <br /> <br />In order to rectify this deficiency two options have been considered. The first option <br />would be to mill out the base course of bituminous pavement adjacent to the concrete and <br />place seven foot concrete section adjacent to the existing concrete curb. This would <br />provide a wide enough width to provide an adequate section for stopping buses. <br />However, this section would result in having a concrete section protruding into an <br />otherwise bituminous pavement on the north side of the street for a distance of <br />approximately 180 feet. On the south side of the street the concrete for the bus stop is <br />located entirely south of the extension of the curb line leading into the bus stop "bump <br />out". Although functional, there are aesthetic concerns with this alternative. A second <br />alternative would be to place a full width concrete section through a 250 foot section of <br />Civic Center Drive, by removing 37 feet of the bituminous base course and replacing it <br />entirely with a concrete section. <br /> <br />At the time of this writing staffis awaiting the receipt of costs fi.om the contractor to <br />facilitate both of these alternatives. <br /> <br />Recommendation: <br /> <br />To be presented at the meeting <br /> <br />Action: <br /> <br />Motion to recommend to City Council that a change order be authorized for one of the <br />alternatives described above. <br /> <br />Reviewed By: <br />Public Works Director/Principal Engineer <br />Fire Chief <br /> <br />PW: 05/16/06 <br /> <br /> <br />
