MAYOR AND CITY COUNCIL FROM: WILLIAM A. SIMMONS CITY ADMINISTRATOR COUNCIL COMMUNICATION DATE: May 20, 1997 SUBJECT: AWARD BID PAGE 2 CONTINUED ORIGINATING DEPARTMENT: Public Works SUMMARY: Alternate 2, open channel construction, wetlands construction and regrading was to be accomplished on the Lastoka Open Space. The Public Works Department requested a limited impact grading permit from Boulder County. On Wednesday, May 14, 1997 Boulder County Open Space notified the Public Works Department that there were issues and concerns regarding the proposal to regrade the open space, establish a wetlands area, and regrade a channel way. Therefore, the Public Works Department has determined that a contingency is available and the project can be constructed starting immediately east of Highway 42 and staying on City owned park and open space land. This means that the proposed work on Boulder County open space would be postponed or deleted. The improvements deleted will not effect the reduction in the flood plain west of the railroad tracks. At this point Public Works is still waiting fmal approval of easements from Boulder Valley School District (BVSD) to cross the Louisville Middle School property and a railroad crossing permit for boring under the BNRR. Discussion with both entities have indicated approvals are in process and should be provided within two weeks. The Public Works Department is recommending that the project be awarded in a combination of the Base Bid plus alternate 1 and 3. This will provide for the necessary storm sewer capacity from east of Highway 42 to Enrieto Park. Award of Alternate 1 would be contingent upon obtaining the necessary easements from BVSD. The Public Works Department is also recommending that bid award be contingent upon the low bidder entering into contract Change Order No. 1 reflecting all work around the school being completed prior to school opening and identify any additional cost associated with possible delays on the railroad crossing agreement. Total construction cost including the Base Bid, Alternate 1 and 3 and Change Order No. 1 will be approximately $635,262. Total project expense will be approximately $740,000. RECOMMENDATION: Approval of Drainageway A Base Bid plus Alternate 3 bid award to Midtown Material Storage Company, Inc. per their unit price bid of $318,472.40, Approval of bid award for Alternate 1 contingent upon obtaining necessary easements from BVSD in the amount of $306,789.87, authorization to enter into Change Order No. 1 identifying completion of work in the vicinity of Louisville Middle School prior to school opening in August and adjusting the contract prices to reflect any additional effort needed to rephase the project.
