RE:

May 13, 2008 Agenda Item

 

Please include the following item on the City Commission consent agenda for consideration at the May 13, 2008 meeting:

Approval of Change Orders No. 1-4 for 25th Terrace, O’Connell Road to Franklin Road. These are to date the construction contract change orders covering all outstanding items. Total change orders amount is $50,728.18.

 

Project Details.

Major construction items included in change orders are:

  • Installation of two sanitary sewer crossings and two manholes in 25th Terrace.  This change was at the request of Douglas County.  This cost will be reimbursed by Douglas County.  (Change Order No. 1:  +$27,643.00)
  • Elimination of side roads south of the concrete approach to Fairfield Farms.  This change was made due to the sanitary sewer for Fairfield Farms not being in place prior to construction of 25th Terrace.  This eliminates the need to remove pavement for the installation of the sanitary sewer.  (Change Order No. 2:  -$21,541.82)
  • A new channel was graded to allow new storm sewer to drain instead of connecting the storm sewer in Fairfield Farms which was not in place prior to construction of 25th Terrace.  Additional pipe and erosion control was required with the new channel work.  (Change Order No. 3: +$37,862.00)
  • Installation of under drains in sub-grade at Stations 17+50 thru 22+00 due to a spring found by contractors.  This will help eliminate the water in the sub-grade.  (Change Order No. 4:  +6,765.00)

 

Project Status.  The project is 35% complete and is scheduled to be completed within the contract allowable time.

 

Project Funding. The project is funded 100 % from the benefit district.
