City Hall Parking Lot Construction AcceptanceTx~ crrY of Dubuque ~T T ~ ~ All-am~ica city ~,J & ~t Masterpiece on tl~e Mississippi 2007 TO: The Honorable Mayor and City Council Members FROM: Michael C. Van Milligen, City Manager SUBJECT: City Hall Parking Lot Reconstruction Project CIP 7301843 DATE: November 26, 2007 City Engineer Gus Psihoyos is recommending acceptance of the construction contract in the amount of $673,974.08 for the City Hall Parking Lot Reconstruction Project, as completed by Portzen Construction, and establishment of the Final Schedule of Assessments. This project was 10.92% over the original contract in the amount of $607,607 mainly attributable to the following factors: • Relocation of the watermain through City Hall -During construction of the underground utilities, the Engineering Department and the Water Department felt that the existing 4" main running through the City Hall basement should be relocated. This was done partially to avoid any possibility of a watermain failure adversely affecting the foundation of City Hall. • Additional quantities of Hot Mix Asphalt Pavement -additional quantities of HMA pavement were required as a result of replacing the watermain in Iowa and 13tH Streets as part of the City Hall watermain relocation. • Additional curb on Central Avenue was required to be replaced to accommodate the new decorative sidewalk and pedestrian lighting. • Additional sidewalk needed to be removed on the Iowa Street side of City Hall to accommodate changes in grades for the driveway approach. Heat tubes were added to this new sidewalk to accommodate a future sidewalk heating system in this area. I concur with the recommendation and respectfully request Mayor and City Council approval. 2 ~ l~ - Mi ael C.

Van Milligen, City Manag r FROM: Gus Psihoyos, City Engineer --~ ~, SUBJECT: City Hall Parking Lot Reconstruction Project CIP 7301843 DATE: November 21, 2007 INTRODUCTION Dubuque All-America City 2007 The enclosed resolutions provide for the acceptance of the construction contract and the establishment of the Final Schedule of Assessments for the City Hall Parking Lot Reconstruction Project. DISCUSSION The City Hall Parking Lot Reconstruction Project provided for the reconstruction of underground utilities, adjacent sidewalks, perimeter lighting, parking lot sub-base and the construction of new concrete pavement. The project also provided for the installation of new perimeter fencing that complements the historical features of City Hall. All existing overhead electric lines and services were transferred to underground. A new generator pad was constructed to support the placement of the new electrical transformer, street light control cabinets and cable tv cabinets. Brick piers were created to support screening that was constructed under a separate contract. The project included the following utility upgrades and repairs: • The reconstruction of 2 deteriorated brick manholes. • The reconstruction of approximately 520 lineal feet of watermain, mainline valves, fire hydrants, and the replacement of 3 lead commercial water services. The cost of the individual lead commercial water service replacements will be assessed to each respective private property owner. • The project also provided for the construction of approximately 590 lineal feet of new storm sewer and 2 catch basins to complement bioswales found in the medians. This included tying the roof drains of City Hall into the storm sewer system to minimize icing in the winter. The installation of fiber optics and telecommunications conduit infrastructure to improve connectivity with City Hall. This included 485 lineal feet of 4" conduit with inner ducts and the construction of two fiber optic manholes. • The installation of 6 electrical service pedestals and 6 water lawn hydrants for the future electrical and water needs for the Farmer's Market and other festivals. • The existing 4" watermain that went through City Hall was removed and re-routed around City Hall. The 4" main was replaced with an 8" main to account for current and future demand. The sidewalks were replaced with new decorative buff-colored sidewalks that follow the downtown decorative sidewalk standard and are illuminated at night by historic pedestrian lighting. Also, as Alternate 1, heat tubes were installed along the 13th side of City Hall for future connection to the heat pump system. DISCUSSION The City Hall Parking Lot Reconstruction Project was completed by Portzen Construction, Inc. of Dubuque, Iowa, in the final contract amount of $673,974.08, which is a 10.92% increase from the original contract in the amount of $607,607.00. The additional cost of this project can be attributed to the following: • Relocation of the watermain through City Hall -During construction of the underground utilities, the Engineering Department and the Water Department felt that the existing 4" main running through the City Hall basement should be relocated. This was done partially to avoid any possibility of a watermain failure adversely affecting the foundation of City Hall. • Additional quantities of HMA Pavement -Additional quantities of HMA pavement were required as a result of replacing the watermain in Iowa and 13th Streets as part of the City Hall watermain relocation. • Additional curb on Central Avenue was required to be replaced to accommodate the new decorative sidewalk and pedestrian lighting. • Additional sidewalk needed to be removed on the Iowa Street side of City Hall to accommodate changes in grades for the driveway approach. Heat tubes were added to this new sidewalk to accommodate a future sidewalk heating system in this area. RECOMMENDATION I recommend that the City Council accept the improvements and authorize the payment of the contract amount of $673,974.08 to the contractor for the City Hall Parking Lot Reconstruction Project.

The project, as outlined, will require Special Assessments in the amount of $5,454.24. SPECIAL ASSESSMENTS Based upon final construction costs, the total amount of Special Assessments for all associated improvement (including water services) is in the amount of $5,454.24, which is 9.2% below the preliminary special assessments estimates that were presented to the property owners and approved at the project public hearing. This decrease is attributed to lower bid item costs for water items versus what was originally estimated.
