2) Consider Change Order for Improvement Project 03-20 Northwest Sanitary Sewer and Watermain Extension Public Works Director Olson explained upon initiating the construction of the northwest sanitary sewer, soil conditions were encountered where organic soils were discovered to be deeper than the bottom of the sanitary sewer. Soil investigations allowed for the relocation of the sanitary sewer to avoid the excessively deep organic soils. This situation has caused a number of modifications to the project and consequently to the agreement with the contractor, LaTour Construction. Change Order No. 1 outlines the nature of these changes, along with the financial and scheduling implementations of these changes. Staff and the Public Works Committee recommend that Change Order No. 1 with LaTour Construction be approved in the amount of $14,184 and extending the contract completion date by 20 days. Councilmember Elvig noted the original estimate was as high as a possible $100,000 increase. He commended staff on their work in rerouting this and the lower amount of the increase. Motion by Councilmember Elvig, seconded by Councilmember Cook, to ratify the recommendation of the Public Works Committee in Case No. 2 and adopt Resolution #06-05- 170 to approve Change Order No. 1 with LaTour Construction in the amount of $14,184, and to extend the contract completion date by 20 days. Motion carried. Voting Yes: Mayor Gamec, Councilmembers Elvig, Cook, Jeffrey, Olson, Pearson, and Strommen. Voting No: None. Consider Change Order for Improvement Project 05-22 Ramsey Town Center Phase 2 Segment 1 Public Works Director Olson explained this project includes the construction of Civic Center Drive between Zeolite and Sapphire Streets. One element of this street includes a "bump out" in the street section to accommodate the bus loading zone in front of the municipal parking structure. Concrete pavement is required through the area where buses will be braking and accelerating to prevent rutting and shoving that would be anticipated if bituminous pavement were utilized. The plans called for a 1 O-foot wide concrete bus parking section on the south side of the street, but made an accommodation for only a 5-foot segment on the north side. If constructed in this manner only the right side on the bus wheels would be braking on concrete pavement. In order to rectify this deficiency two options were considered: Option One would be to mill out the base course of bituminous pavement adjacent to the concrete and place a seven foot concrete section adjacent to the existing concrete curb. This would provide a wide enough width to provide an adequate section for stopping buses. However, this section would result in having a concrete section producing into an otherwise bituminous pavement on the north side of the street for a distance of approximately 180 feet. On the south side of the street the concrete for the bus stop is located entirely south of the extension of the curb line leading into the bus stop "bump out". Although functional, there are aesthetic concems with this altemative. The estimated cost for this option is $11,635. It is suggested that the concrete section be tapered for a more streamlined appearance. City Council / May 23, 2006 Page 17 of 20
