RE:

Overland Drive & Stoneridge Drive

Project No. 19-CP6-506(BD) & 25-CP8-806(BD)

 

Please include the following item on the City Commission consent agenda for consideration at the October 7, 2008 meeting:

Approval of Change Order No. 1 for Overland Drive & Stoneridge Drive. The depth of the existing waterline that is being tied into was discovered to be lower than originally assumed. This caused a change in the elevation needed to construct the new waterline.  The extra work is on the Stoneridge Drive portion of the project and this is the first construction contract change order. Total change order amount is $18,182.41.

 

Project History.  Resolution No. 6655 was approved on June 13, 2006 authorizing issuance of $2,220,000 in general obligation bonds to be paid for by a benefit district for engineering, construction and inspection work for Overland Drive from Stoneridge Drive to Queens Road.  Construction includes street, storm sewer, and waterline improvements.

Resolution No. 6702 was approved on February 6, 2007 authorizing issuance of $2,750,000 in general obligation bonds to be paid for by a benefit district for engineering, construction and inspection work for Stoneridge Drive from 6th Street to Overland Drive.  Construction includes street, storm sewer, and waterline improvements.

The Stoneridge Drive and Overland Drive projects were bid as two separate sections that were combined as one contract. 

The construction contract was bid on March 25, 2008. The construction contract was awarded to RD Johnson Excavating Company on April 1, 2008 for a total amount of $1,690,649.46.
