On October 20, 2020 City Council approved an agreement and a proposal from Granite Inliner, LLC in the amount not to exceed $133,258.50 for the sanitary sewer gravity main rehabilitation. The agreement included the same conditions and unit pricing as the current City of Plantation ITB#141-14. The usage of the contract and its pricing are in accordance with the City's purchasing procedures and guidelines.
As Council is aware, this type of project has been included annually in the Public Works Capital Improvement Program as a continual proactive approach to rehabilitate an aging infrastructure. This type of rehabilitation method has a considerable reduction in cost from traditional pipe laying construction because it eliminates the cost of restoration and allows the existing facilities to remain in place with no disruptions to the general public. For this project 2,844’ LF of existing eight inch (8”) clay pipe was cleaned and videoed. 2,844’ LF of eight inch (8”) cured-in-place-pipe (CIPP) was installed. Finally, 48 reinstated services or sewer laterals were installed. Two areas consisted of rear easement where the work was conducted, and all other areas work was performed in the City’s front right of way.
The change order was a result of the rehabilitation of 449’ LF of eight inch (8”) gravity sewer lines, 17 reinstated service points, and five (5) areas that consisted of rear easement work. During the project staff identified a depression created by the pipe’s declined condition. No owner’s contingency was included in the contract which created a positive change order resulting in a $143,420.50 final project cost.
