Title

Consider a resolution authorizing the Mayor to execute a Contract with PM Construction & Rehab, LLC for the Chandler Creek Pipe Bursting Replacement Project.

 

Body

This project will replace 732 linear feet of 36-inch diameter wastewater line located on the Chandler Creek Interceptor.  This wastewater line was very deteriorated when the City inspected the large gravity interceptors in search of large sources of infiltration and inflow (I&I) in the Spring of 2022.  This pipe was initially installed in 1984 and extends through an area where there is a high groundwater table.  The line originally installed has deflected and lost stability so it is imperative to replace the line before there is a catastrophic failure. 

This project will replace the entire pipeline using pipe bursting which is a trenchless technology.  The wastewater line will be replaced with a 36-inch diameter high density polyethylene line with a thick pipe wall to enhance the wastewater line stability.  Open cut and replacement of this line would be very difficult because of the proximity of the line to the Upper Brushy Creek Water Control Improvement District flood control pond and subsequent high groundwater level.  Pipe bursting replacement was selected because of the short amount of time that it can be completed and the limited amount of open cutting that is required.      

PM Construction & Rehab, LLC has completed several projects with the City in the past and is being recommended to perform this work through a BuyBoard contract.

 

Cost: $967,000
