Title
Resolution to Approve a Change Order to the Contract with Site Development, Incorporated for the West Park Improvements Project ($27,776.00)
Memorandum
Attached for your review and approval is a resolution to approve a change order to the contract with Site Development, Incorporated in the amount of $27,776.00.
The improvements to West Park included improvements to stormwater quality and enhancements to the park, including access improvements, seat walls in the hillside at the historic bandshell, renovations to the bandshell, boardwalk and pond overlook construction, parking lot reconstruction, basketball court replacement, prairie, wetland and tree planting. The project included installation of eight hydrodynamic separaters that were designed to reduce sediment and phosphorus inputs into the Allen Creek.
City Council approved the contract with Site Development, Incorporated (Bid #4052) for construction of the project in the amount of $1,443,000.00, including a construction contingency in the amount of $144,300.00 (10%) to cover contract change orders, for a total construction budget of $1,587,300.00. Five previous change orders have been approved within the 10% contingency amount to cover unforeseen changes, including undercutting due to poor soils, repairs from extensive storm damage, revisions to the stormwater structures in the park, additional work on Seventh Street due to conflicts with underground utilities, electrical service relocation, additional landscaping, and earthwork in conjunction with the house removed on Chapin.
In November, 2010, one of the hydrodynamic units failed. This sixth change order directed the contractor to provide barricade fencing around all eight units to prevent traffic and pedestrians from entering the area, backfill the hole created by the collapse, remove the weir wall from the diversion structure, and bulkhead of the pipes to prevent backwater from entering the structures downstream.
This proposed change order of $27,776.00 brings the contract amount above the 10% contingency originally approved by City Council on November 16, 2009 (Resolution R-09-468) by $24,335.98 or 1.5% of the approved contract amount. Funding for this change order is from Public Services "West Park Storm System Modifications", which was established to cover work in conjunction with the failure of the unit.
