Analysis
On August 16, 2016 (16-5928) City Council approved a professional engineering contract with Freese and Nichols, Inc. (FNI) for services relating to landfill levee remediation services in the amount of $60,621. The contract was to evaluate data and recommendations already in existence and to recommend a design that will bring the levee back to it's original form and function while minimizing future damage.
The project is being accomplished in a phased approach as follows:
-Phase 1: Alternative Analysis
-Phase II: Plans, specifications, and construction management of selected remediation determined from Phase I
Change Order/Amendment No. 1 for $47,195 approved by the City on December 28, 2016 evaluated the condition of two equalization pipes that were placed beneath the Landfill River Levee built by the US Army Corps of Engineers in 1987. The two separate pipes connect the water within the Trinity River to the oxbow river channel that was separated from the main river channel by construction of the levee. As a portion of that effort, it was necessary to ascertain the condition of the two equalization pipes. The City has requested that FNI perform a pipe condition assessment during Phase 1 instead of later during the subsequent design phase so that this information was available for development of opinion of probable construction cost during the Alternative Analysis.
The current Change Order/Amendment No. 2 for $20,000 includes the services of ACE Pipe Cleaning Inc. (ACE), as a subcontractor to FNI, to perform the needed pipe cleaning and inspection services, as well as FNI’s coordination for the pipe assessment process, evaluation of results, and sub-consultant management....
