ADDENDUM%20NO%201%2026017%202026%20Water%20Mains%20Replacement

The City of Salina is seeking contractors to replace its municipal water distribution mains under Project 26017. The addendum clarifies general notes, removes a pipe‑thickness requirement for directional bore installations, and provides technical specifications for valve‑box removal, shoring, top‑soil placement, meter‑pit installation, and material selections (ductile‑iron, copper, limited HDPE). Bidders must acknowledge receipt of this addendum and comply with OSHA shoring requirements. • Remove existing valve boxes at least 24 in. below finish grade; roadway boxes require a 3 ft × 3 ft excavation. • Provide 6 in. of commercial‑grade topsoil in all excavations and disturbed areas. • Directionally bored ductile‑iron pipe follows pressure class 350 (≤12 in.) or 250 (≥16 in.) – the Class 50 thickness clause is removed. • Meter‑setter installation details, HDPE usage restrictions, and shoring obligations are detailed in the Q&A section.
