Nibley City released a bidding Q&A document on November 12, 2026, to provide clarifications for the Nibley City Regional Drain Line project. The document addresses technical questions regarding materials, site access, and construction specifications for potential bidders.
The project is estimated to cost near $230,000. According to the November 12 document, final completion is scheduled for June 30, with punch list items due by July 1. While work during the irrigation season must be coordinated with canal companies, the city has already coordinated the extent of the work with the canal company. Contact information for the College Irrigation Company is included in the General and Special Provisions for coordinating watering schedules and work impacting the canal.
The bidding document clarifies several technical requirements. While the city is not rigid on finishes or materials for ironworks, it requires that any modifications do not hinder the design or the ability to secure structures. For areas not within an existing or future roadway, the city will allow backfilling with native materials above the pipe zone. In areas with high groundwater, the city allows the use of 1-inch wrapped clean rock for construction, provided clay dams are installed every 200 linear feet.
Regarding site visits, there is no mandatory pre-bid or site visit, but the site can be accessed from Maple Valley Rd (1500 West) via 3200 South. Visitors are advised to remain within the drainage easement shown on the plans. The document also notes that the existing 10-inch land drain must remain in service during construction.
Soil types for the project are estimated to be loam, silty clays, silty clay loams, and clay loams. Groundwater is estimated to be between 24 and 48 inches below the existing grade. For dewatering, the contractor is responsible for monitoring and reporting to ensure discharge to the slough meets effluent levels within the DEQ/DWQ Dewatering permit (UPDES Permit No. UTG070000).
The city maintains the right to reject bids if action is taken within 30 days, though the Bid Bond Hold is 90 days.
