Title
Discuss and consider action to approve a change order with S.J. Louis Construction of Texas, Ltd. in the amount of $401,928, for work associated with the Secondary Colorado River Raw Water Line Bid Package 3 (WA2201), and authorize the City Manager to execute the same.
Summary
The City’s existing Colorado River Raw Water Pump Station, located near the confluence of Boggy Creek and the Colorado River, in southeast Austin currently delivers water a distance of approximately 15 miles in an existing 30-inch diameter concrete steel cylinder pipe that is over 20 years old. Water is pumped from the Colorado River to Lake Pflugerville and then pumped from the lake to the City’s Surface Water Treatment plant and ultimately delivered to the City’s distribution system. Recently in early February 2026, a pipeline rupture occurred in the existing 30-inch pipeline segment within the steel casing at the Boggy Creek crossing which resulted in a disruption of raw water delivery to the lake.
Change Order modifications include: excavation, dewatering, with trench shield to expose pipeline and determine location of pipeline leak followed wtih installation of two 30-inch diameter “T” fittings one on each side of the Boggy Creek and installation of 250-300 linear feet of 24-inch high density polyethylene (HDPE) pipeline to route water around the damaged 30-inch pipe segment and across the creek with limestone block ballasts to secure the submerge temporary HDPE pipeline.
Contract Notice to Proceed was issued on 11/14/2024.
Current substantial completion and final completion dates were 5/18/26 and 6/17/26 respectively.
This Change Order results in the revised substantial/final dates 5/25/26 and 6/24/26 respectively.
