10-1.5 FCE133675-1 Addendum 1.pdf

This is Amendment Number 1 to a Request for Bids (RFC) issued by Salt Lake County for construction materials related to the Rose Creek Gabion Baskets project (Solicitation FCE133675). The amendment modifies the original RFC specifications for galvanized steel gabion wire baskets and other materials required for bank stabilization measures along Rose Creek. The project involves supplying Class III riprap (D50 = 12"), 4-8" rockfill, and galvanized steel gabion wire baskets to protect an existing maintenance road from scour erosion. The materials will be used to install 619 linear feet of bank stabilization measures, with installation to be performed by Salt Lake County crews. The RFC closing date is September 10th, 2026, at 1:00 p.m. Suppliers may bid on any portion of the materials without submitting a complete bid across all line items. Construction of the work is anticipated to occur between September 2026 and November 2026. Gabion wire baskets must be delivered to the County operations yard, while aggregate materials should be available for pickup during normal business hours.

Amendment Number 1 specifically revises Specification 31 36 00, Paragraph 2.1.B.5, to establish a minimum elongation requirement of 12 percent for the gabion basket materials. Payment for riprap and rockfill will be based on actual quantities required, which may vary from estimated quantities provided. All material specifications derive from the 2025 APWA Utah Chapter Manual of Standard Specifications and follow APWA numbering codes, modified to address supply and delivery requirements while excluding installation clauses. This procurement is limited to material supply only; installation services are not included and will be performed by County operations crews. Individual bid items may be awarded via separate purchase orders or contracts at the County's discretion.
