Body
BACKGROUND
On September 26, 2018, the 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 riverbank.
On December 8, 2021, the City Council authorized a construction change order for encountered conditions that could not have been anticipated at the time of bid. The additional work was associated with unexpected bends and flow control, manhole rehabilitation, removal of concrete, removal of a failed liner section in the 42-inch diameter pipeline, and installation of erosion protection at a retaining wall. During the completion of construction, the contractor has encountered additional conditions that could not have been anticipated at the time of bid. These items have required additional work and resources not included in the original contract or first change order, including (1) the manufacture, purchase, and installation of additional fittings to address field conditions that did not match utility records, (2) additional modifications and cuts in the field due to beveled joints required to accommodate curves in the existing pipe, and (3) additional flow control restrictions to meet the needs of Dallas Water Utilities plant maintenance and operation activities.
Dallas Water Utilities Department has reviewed these conditions and determined that the changes being implemented by the contractor were 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. 2 to the construction services contract. Approval of this item will allow for the successful completion of the project and will alleviate the risk of the failure for the targeted wastewater interceptors. The change to the contract represents the final accounting needed to close out the contract. All work has been substantially completed and the constructed facilities are fully operational.
