Title
Consider a resolution authorizing the President to execute Supplemental Contract No. 1 to the Phase 2A Water Treatment Plant Expansion Planning Level Evaluation project with Walker Partners to provide Final Design Engineering Services for the Phase 2A Project.
Body
BACKGROUND:
This agenda item is Supplemental Contract No. 1 to the BCRUA Phase 2A Water Treatment Plant Expansion Basis of Design project. The Phase 2A Planning Level Evaluation Project (aka Basis of Design Project) engineering services contract was approved in September of 2023 for a lump sum amount of $198,895. The purpose was to establish a planning level design for the Phase 2A expansion project. The results of this evaluation concluded that the treatment process for Phase 2A will match the existing conventional treatment process implemented during Phases 1A through 1D.
The supplemental contract includes final engineering design services for the Phase 2A water treatment plant expansion, including project management, preparation of construction plans, specifications, bidding documents, stakeholder coordination, and special services such as surveying and geotechnical engineering. Bid and construction phase services will be addressed separately, during the award of the construction bid.
The current water treatment plant (WTP) capacity is 32.5 million gallons per day (MGD).
Construction is underway to complete the Phase 1D expansion thereby increasing treatment
capacity to approximately 42 MGD. This Project consists of final design of the Phase 2A Water
Treatment Plant (WTP) Expansion to further increase treatment capacity to approximately 64.2
MGD. The capacity allocation for Phase 2A is 11.7 MGD to the City of Leander (52.4%) and 10.6
MGD to the City of Round Rock (47.6%). It is anticipated that construction of the Phase 2A
expansion will be substantially complete prior to Summer 2027.
Staff and the Operations Committee have completed negotiations with Walker Partners and reached ag...
