Title
Creekside Subdivision - South Drainage Improvements - Change Order
History
On November 4, 2013, the Board approved awarding the bid for the installation of a new storm sewer in Creekside Subdivision to Superior Excavating Company of Channahon, Illinois, for a cost not to exceed $56,471.15 ($51,471.15 plus $5,000 contingency). This work included the replacement of existing storm sewer pipes servicing the area and the establishment of an overland flow route to convey runoff.
During construction, changes in the plan were required due to unexpected depths of telephone ducts, a gas main conflict and concerns of the neighboring residents. The conflict with the depths of the ducts and gas main required a change from circular storm sewer pipe to elliptical storm sewer pipe and an additional structure. Additional grading was added to aid the adjacent properties in relief of flooding in the rear yards and the overland flow route between the homes has been modified to provide a better slope for maintenance by the homeowners. A change order to the contract is needed. There is $5,000 for contingency that will be utilized. Approval is being requested for an additional $4,000 to cover the change order items.
On December 2, 2013, this item was reviewed and approved by the Public Works Committee and referred to the Board for approval.
Financial Impact
There are sufficient funds available in account 031-6007-470500 to cover the cost of this extra work.
Recommended Action/Motion
I move to approve adding an additional $4,000 contingency to the Creekside Subdivision South Drainage Improvement contract with Superior Excavating Company of Channahon, Illinois.
