Title
Approval of change order and engineering contract amendment for Sewer System Rehabilitation Project 2017
Body
SUMMARY: The work completed and estimated work to complete leaves a contract underrun of $265,609.12.
City staff has discussed other sanitary sewer problem areas with the Engineer and by utilizing the existing unit prices we are able to complete the following:
1. Town Loop - Pipe burst lower two sections on the east side of Town Loop; approximately 315 L F. of 8-inch.
2. Braun St. - Pipe burst from Braun Ct to the east side of Wayne Ave. ; approximately 1,600 L.F. of 8-inch.
3. Braun St. to Diane St. -Pipe burst approximately 900 L.F. of 8-inch line.
4. South of 4th Street to Lantana Rd. - CCTV approximately 4,200 L.F.
The Contractor has asked to add stone backfill in as a unit price item because this additional pipe bursting may require excavation in the roadways which was not previously part of the project.
We have also requested that approximately 7.000 L.F. of sewer be videoed on the north side of Holiday Lake. This CCTV work is different from the originally bid camera work in that it is quite a distance from the road and a majority of the work is in residential back yards which may require cleanup. The Contractor has given the City a price of $5.00 per L.F.
If we move forward with all of the above mentioned work, a change order is required for the stone backfill unit price, the CCTV unit price for the work on the north side of Holiday Lake and a two month time extension. The time extension would require an amendment to the Engineer’s contract for two additional months of hourly inspection. It is estimated that the total budgeted project would be $50,000 under budget when all work is complete.
