ADMINISTRATION RECOMMENDATION Approve the additional contingency fund. FUNDING Funding is available in the amount of $469,175.21, previously appropriated for in the Fiscal Year 2007-2008, Capital Budget, for Construction of the Project as follows: Account No. 389.2332.069357 - $469,175.21 ANALYSIS On December 10, 2008, the City Commission approved the award of a construction contract to Horizon Contractors, Inc. (Horizon) in the amount of $7,683,901, for the construction of the South Pointe Phase II Right of Way Infrastructure Improvement Project. Project Contingency in the amount of $768,390, was also made available for the Project contingency fund. The Project limits include the area bounded to the north by Fifth Street, to the south by Second Street, to the east by Washington Avenue and to the west by Atton Road, excluding Third Street. The Project scope of work includes the replacement of approximately 5,610 linear feet of existing water lines within the alleyways and along 4th Street to enhance the water distribution system pressure; the installation of new storm water infrastructure to meet the Master Plan recommended Level of Service (LOS) throughout the project area which includes approximately 6,160 linear feet of storm drainage collection pipe, approximately 130 drainage structures, andtwenty-one (21) gravity wells; streetscape improvements, including traffic calming measures and enhanced pedestrian access, bump-outs and defined neighborhood entrances; landscaping; pedestrian lighting and parking improvements. On May 4, 2009, the contractor was issued the second Notice to Proceed (NTP) to mobilize and commence the construction activities. The installation of the water mains included in the original scope of work, and the added scope of work (the installation of a 12-inch diameter water main on 4~' Street from Jefferson court to Washington Avenue) is complete. The water mains included in the original scope of work have been placed into service, and the water main included in the new scope of work have been approved to be placed into service by the by the Department of Health (DOH). The work currently in progress includes the placement of the new water meter boxes which are primarily located in the alleyways. The storm water drainage system is 95% complete. The City received the DERM Class V dewatering permit on June 14, 2010, and Horizon commenced the cleaning and testing of the storm water system on June 28, 2010.Once the system has been cleaned, tested, and approved by the City, the final lift of asphalt will be placed throughout the project area. The project street lighting is complete and inspections are in progress for final acceptance by the City. Landscaping and original irrigation improvements are 85% complete, pending testing of the irrigation system and acceptance by the City. The overall project is scheduled to be substantially completed by November 2010. During the construction of the Project, additional scope of work was added to Horizon's contract for the betterment to the overall project as requested by the City. The items that were added are as follows: Adapave and Healthy Tree Fertilization System The original contract scope of work specified the installation of concrete tree grates. During the construction of the Project, the Parks and Recreation Department requested the use of a permeable bound granite aggregate (Adapave, or approved equal) together with the Healthy Tree Fertilization System (RTES). The CIP Department consulted with the City's Planning Department which also recommended and approved the use of the ADA compliant bound aggregate and HTFS for the tree pit treatment. Horizon submitted a cost proposal in the amount of $387,098.16 for the installation of this system at 136 tree pits throughout the project limits; this amount was negotiated down to $340,840.48, approximately $2,506.18 per tree pit. The City also obtained a credit in the amount of $152,250 for the concrete tree grate installation. The total additional cost to the Cityfor the implementation of the City standard tree pit treatment is $188,589.84. Check Valves in Lieu of Mechanical Gate Valves During the course of the construction of the storm drainage system, issues were raised regarding the performance and maintenance requirements for the mechanical gate valves that were specified by the project team. The City's Public Works Department and Wolfberg Alvarez and Partners, the design Engineer of Record (EOR) agreed that the use of inline check valves would be more suitable than the mechanical gate valves specified. On January 5, 2010, Horizon submitted a proposal for the substitution of the specified six (6) Neenah 5050 Mechanical Gate Valves and two (2) additional inline check valves. The valves are intended to keep tidal surcharge from impacting areas east of Michigan Avenue. The FOR reviewed and approved the substitution, including an additional two (2) inline check valves for a total of eight (8) valves (two 8-inch diameter, three 15-inch diameter and three 24-inch diameter) in the amount of $43,252.85. The prices submitted were reviewed by the project team and found to be fair and reasonable. T:/AGENDA/2010/REGULAR/SOUTH POINTE IMPROVEMENTS PHASE II CONTINGENCY MEMO On December 9, 2009, the City requested that Horizon submit a cost proposal for the milling and resurfacing of the south half of 2nd Street from Washington Avenue to Alton Road (south half). This Work was not included in the original project boundaries. The City also requested that Wolfberg Alvarez and Partners (Wolfberg) re-evaluate the 2nd Street and Meridian Avenue intersection to ensure that the existing cross slopes and grade elevation changes complied with established minimum standards. Wolfberg confirmed the existing conditions at this intersection exceeded the minimum standards and completed a design for the 2"d Street & Meridian Avenue intersection on April 25, 2010. Wolfberg issued Revision No. 22 to the construction documents drawings and Horizon was requested to include this work in the cost proposal for milling and resurfacing the south half of 2"d Street from Washington Avenue to Alton Road. On May 25, 2010, Horizon submitted a cost proposal and it was negotiated to the final amount of $78,827.97. Michigan Avenue and 2"d Street Intersection Modifications On December 10, 2009, Wolfberg issued revision 16 which added approximately 15 LF of storm drainage line, a drainage structure and grate to address the need for additional storm water collection system requirements. This is additional scope of work that was not contemplated in the plans and verified in the field as being necessary to accommodate the drainage flow pattern. On June 6, 2010, Horizon submitted a cost proposal for the work in the amount of $9,518.49. The City, Wolfberg and Horizon negotiated and agreed on a fair and reasonable price of $7,474.81 for this work. Jefferson Court Storm Sewer During the reconstruction of the Jefferson Court alleyway, an old 24-inch ductile iron pipe was found a few inches below existing grade. The pipe was old, brittle and further damaged by the reconstruction of the alleyway. The Public Works Department confirmed that this abandoned sewer pipe had been converted to a storm water conveyance pipe and the City wished to retain it in use. A repair was developed which removed the damaged section and replaced it with a Class 53 ductile iron pipe (thick pipe wall) so that the existing pipe can remain in service. On May 28, 2010, Horizon submitted a cost proposal for the repair of the existing sewer pipe in the amount of $1,243.17. The proposal was negotiated in the final amount of $1,029.74. Additional Irrigation Systems During plan development, Wolfberg was concerned that the budget could not provide for swale irrigation along Euclid, Jefferson and Michigan Avenues. The Parks and Recreation Department requested that irrigation be added to the project to fully irrigate the areas that will receive sod. The original scope of work includes irrigation bubblers in all tree pits along 4~' Street and 2"d Street and irrigation spray heads at all bump-outs that will receive trees. No irrigation was planned for the "swale areas" along the Avenues due to the perceived lack of funding during design development. T:JAGENDA/2010/REGULAR/SOUTH POINTE IMPROVEMENTS PHASE II CONTINGENCY MEMO With the assistance of the Parks and Recreation Department, cost proposals have been requested from three (3) vendors that provide irrigation services to the Parks and Recreation Department. On a parallel path, Horizon was also requested to provide a cost proposal to integrate the additional irrigation along the swales. As of this writing, only two proposals are in receipt. An estimated budget of $150,000 is anticipated to accommodate this request. A summary of the additional funding request is as follows: Adapave & Healthy Tree Fertilization System $188,589.84 Check Valves $43,252.85 2"d Street & Meridian Ave Intersection / 2"d Street Milling /Resurfacing $78,827.97 Michigan Avenue & 2"d Street Avenue $7,474.81 Jefferson Court Storm Sewer $1,029.74 Additional Irrigation System on Avenues $150.000.00 Additional project contingency requested $469,175.21 CONCLUSION: The Administration recommends the implementation of the additional owner requested items and betterment requests for the South Pointe Phase II Project and requests that additional funding in the amount of $469,175.21 be added to project contingency to allow for this work to be performed. This funding is available from South Point Capital Funds previously appropriated for in the Fiscal Year 2007-2008, Capital Budget for the Project.
