The details
The actual cost of the project that Collier Engineering and Design was hired to design could fall below $949,216—a figure that includes a 10% contingency to protect the city from unforeseen circumstances, according to city documents.
Bull-G Construction’s base bid was $862,924.
Five other base bids were received:
- Brother Group, $892,062
- Tejano Utilities, $949,865
- Lopez Utilities Contractor, $1.1 million
- S-Co Incorporated, $1.3 million
- PM Construction, $1.5 million
Elizabeth Wick, a project manager with the city of Bastrop, emphasized that the project is necessary, as the existing 10-inch interceptor north of Hwy. 71 does not have full-pipe capacity to accommodate future development in the area.
An interceptor is a pipe that collects wastewater, while full-pipe capacity refers to the maximum flow rate a pipe can handle when it is completely full.
The scope of the sanitary sewer pipe bursting project includes:
- Upsizing 3,620 linear feet of wastewater pipe from 10 to 12 inches
- Adding 70 linear feet of 15-inch wastewater pipe with steel casing
- Adding 715 linear feet of 15-inch wastewater PVC pipe to an existing 36-inch gravity main
The outlook
The sanitary sewer pipe bursting project will be financed with $708,050 in certificates of obligation from 2022 and $241,166 through the wastewater fund balance, according to city documents.
