RECOMMENDATION It is recommended that the City Council approve a Resolution Accepting Completion of Petaluma Boulevard North Water Main Replacement — Lakeville Street to B Street, City Project No. C67501304. BACKGROUND On September 13, 2004, the City Council approved a fire sprinkler retrofit, Ordinance No. 2194 N.C.S., for existing buildings in the Historic Downtown District. The Ordinance requires the installation of automatic fire sprinklers in pre - existing buildings in the historic downtown business district, which is located south of Washington Street, once the City installs an appropriate sized water main and fire services to the curb. The property owners will then be responsible for installation of the lateral service from the curb line into the building. Property owners with a change of use or have basements or space below street grade are required to install fire sprinklers no later than December 31, 2023. All other buildings need to install fire sprinklers no later than December 31, 2029. Approximately 29 properties within the Historic Downtown District require fire sprinkler installation. The downtown businesses and residents were being served with a 50 to 75 year old 4 -inch water main. This project replaced the existing 4 -inch water main in Petaluma Boulevard North, from Lakeville Street to B Street, with a new 12 -inch water transmission main, new service laterals, new fire service laterals, and fire hydrants. This project provided new fire service laterals to the back of curb, which will significantly reduce maintenance costs. This project replaced approximately 3,060 linear feet of water main and approximately 300 feet of sewer main along addresses 3 — 41 Petaluma Boulevard North. Bids were opened on April 6, 2016. On May 2, 2016, the City Council authorized the award of the construction contract for Petaluma Boulevard North Water Main Replacement Project — Lakeville Street to B Street to Team Ghilotti, Inc. (TGI) of Petaluma in the amount of $2,895,824. Construction began in June 2016.and was completed in July 2017. DISCUSSION The project was originally designed with concrete plugs for the water main trench and micro surfacing of Petaluma Boulevard North. After award of the contract, the difficulty of working in the busy downtown business district was discussed and TGI expressed that the concrete plugs for the trench would require significant trench plates on the road and would be an inconvenience for the merchants and customers. TGI proposed 6 -inch asphalt concrete (AC) plugs in lieu of concrete and 2 -inch grind and overlay in lieu of micro surfacing. The City re- negotiated the credits and agreed to the proposal with an edge grinding of the existing pavement and providing a 2 -inch asphalt overlay of Petaluma Boulevard North after the underground pipe installation and trench repair is completed. The project was managed and inspected by Public Works and Utilities engineering staff with the assistance of Coastland Civil Engineering, Inc., for inspection of nighttime work. The final contract amount is $3,030,718.46, which includes seven change orders for a total amount of $301,923.46 for miscellaneous work tasks completed during the construction on a time and material basis for the various unknowns encountered. Change order #1 in the amount of $140,874 was for the agreed changes made to the contract for the AC plug and addition of 2 -inch grind and overlay in lieu of micro surfacing. The proposed action meets Council Goal: "Plan for and implement priority capital projects as funding permits ". FINANCIAL IMPACTS Council approved a project budget of $4,241,824, which was funded by water and wastewater capital funds. 2 Uses Approved Budget, Actual Project Costs Design $ 205,000 $ 199,000.00 Legal $ 12,000 $ - Construction Contracts $ 2,895,824 $ 3,030,718.46 City Furnished Materials $ - $ 30,000.00 Construction Management $ 430,000 $ 430,000.00 CIP Overhead $ 102,000 $ 102,000.00 Administration $ 22,000 $ 22,000.00 Project Contingency $ 575,000 TOTAL $ 4,241,824 $ 3,813,718.46 Funding Sources Waste Water Capital $ 212,091 $ 190,686 Water Capital $ 4,029,733 $ 3,623,033 Note: City staff salary and benefits costs are included in appropriate project phases for the project.
