BACKGROUND
On September 26, 2018, City Council authorized a construction services contract with Oscar Renda Contracting, Inc. for the rehabilitation of approximately 12,515 feet of critical wastewater interceptors with identified condition deficiencies. The project includes the rehabilitation of 42-inch, 54-inch, and 120-inch wastewater interceptors, point repairs to an existing 72-inch wastewater interceptor, and the construction of reinforced concrete retaining walls to protect these critical interceptors from continued erosion of the adjacent river bank.
During construction, the contractor encountered conditions that could not have been anticipated at the time of bid. The existing 120-inch pipeline was found to have unexpected bends and concrete encasement, the 42-inch pipeline required removal of a failed liner section, a section of sheet piling and flowable fill was required to protect the existing 72-inch until the protective wall could be completed, and additional work is required to properly rehabilitate some manholes along the 72-inch pipeline. These unforeseen conditions have required the procurement of special pipe joints, more extensive wastewater flow control and specialized rehabilitation methods, extended labor, and additional time to complete the project.
Dallas Water Utilities and the engineer for the project have reviewed these conditions and determined that the changes being implemented by the contractor are necessary to complete the contract work. Oscar Renda Contracting, Inc., has provided an acceptable proposal for these changes and this action will authorize Change Order No. 1 to the construction services contract. Approval of this item will allow for the successful completion of the project and reduce the likelihood of failure for the targeted wastewater interceptors.
