Text of Legislative File CM-2023-034
On February 24, 2022, the City entered an Engineering Services Contract with UA Engineering, Inc. to
design water, wastewater, and storm water improvements in the Round Rock West neighborhood. The
improvements are needed to help alleviate existing drainage issues and to replace an aging
infrastructure.
The scope of services included in the contract are surveying, engineering analyses, design, permitting, and
preparation of construction drawings. During the design process, unexpected conflicts arose between the
proposed storm water system and existing dry utility facilities. To avoid these conflicts, it requires
additional effort on the storm water design and drainage easement coordination.
Supplemental No. 1 would provide funding to redesign the proposed storm water system so it would
meet the minimum clearance distance from existing facilities.
The current contracted amount is $365,901.25. Supplemental No. 1 adds $31,159.59 to the original
contract and would increase the total contracted amount for UA Engineering to $397,060,84.
Cost: $31,159.59
