About this file
This document is an addendum summary for a federal solicitation to rehabilitate the water and wastewater systems at Acadia National Park in Winter Harbor, Maine. The solicitation is being conducted by the National Park Service National Office within the Department of the Interior. The addendum provides revisions to plans, specifications, and contract documents for the rehabilitation project. Key revisions include adding building attachment brackets and clarifying gravel thickness on plans, revising existing pipe labels and profiles, changing level controls from transducers to floats, revising conduit and enclosure types, clarifying fuel piping ratings and expansion fitting requirements, and adding corrosion resistance notes. It also revises pump voltages, adds gauges and valves, and provides a water treatment plant and clearwell level indicator narrative. The contract price schedule was revised to modify the description and quantity for a contract line item regarding cured-in-place pipe.
