About this file
This document is Addendum #1 to a Request for Quotes (RFQ) issued by Marion County, Oregon for the Sinker Creek Bridge Micropile Installation project (PW1659-25). The addendum, dated 4/7/2025, provides clarifications and revisions to the original solicitation, including a revised plan set and responses to four key contractor questions. The questions address bridge load capacity, tree removal responsibilities, reinforcement bar sizing, and micropile foundation design alternatives. Specifically, the county clarified that the existing bridge should not be used for access, a 2.5-mile detour is available, the county will handle tree removal, the reinforcement bar size is #14 (revised from #13), and alternative micropile casing sizes may be considered if structurally viable.
The addendum does not introduce new pricing terms, set-asides, or funding details. It focuses on technical clarifications to ensure potential bidders have accurate information for preparing their quotes. The document indicates the quote covers only micropile installation items within a specified area on the project plans, suggesting a focused scope of work. No incumbent vendor information or specific budget constraints are revealed in this addendum. The primary purpose appears to be providing precise technical guidance to potential contractors to facilitate accurate and compliant quote submissions for the bridge infrastructure project.
