The Dalles East Fish Ladder Auxiliary Water Supply Emergency Backup System

The U.S. Army Corps of Engineers (USACE), Portland District intends to solicit a competitive firm fixed-price contract for The Dalles East Fish Ladder Auxiliary Water Supply Emergency Backup System.

The purpose of this project is to construct, per provided plans and specification, an emergency backup supply of water to the auxiliary water system (AWS) that feeds the existing fish ladder at the Dalles Dam. A single 10-foot-diameter (inner diameter) conduit will convey the design discharge water by routing flow through a concrete monolith into a new concrete value vault buried under the downstream parking lot, and discharging into the existing auxiliary water supply chamber through 2- 7 foot diameter holes through the concrete ladder walls. In order to accommodate a 10' bore through the existing dam a precast concrete structure will be place in the pool with a steel cofferdam system. Upstream work will require extended diving operations in depths of approximant 70 feet. The emergency backup system consists of the following major features:

a. Upstream underwater concrete foundation for precast units.
b. Precast pier segments with guide slots for closure gate, dewatering bulkheads, and trash-racks. Segments are expected to weigh approximately 320,000 lbs. each.
c. Attachment of the precast piers to the dam face and grouting of the joints.
d. Dive work requirements (Depths of approximant 70 feet).
e. Fabricated Hydraulic Steel Structures (HSS) (closure gate and dewatering bulkheads)
f. Fabricated steel trash-racks.
g. Modification of Monolith 5 deck guardrail.
h. A 10-foot and two 7-foot diameter steel penstocks.
i. The penetration bore hole through Monolith 5. The inlet is to be a bell-mouthed circular conduit inlet normal to the dam face.
j. Several concrete thrust blocks for 10-foot-diameter and 7.5-foot-diameter supply conduits.
k. Pipe supports for the 7-foot diameter penstocks spanning the junction pool.
l. Concrete valve rooms with personnel access and work access platforms.
m. Removal and replacement of AWS concrete deck for pipe installation.
n. A 10-foot-diameter butterfly valve and two 7-foot-diameter butterfly valves.
o. Two 10-foot orifice plates for energy dissipation.
p. Two 7-foot orifice plates for energy dissipation.
q. Pipeline venting.
r. Drain pipe system including isolation valves and check valves.
s. Three 20 ton Steel lifting beams.
t. Electrical lights, receptacles, disconnect switches, and remote control stations for the valves and the valve rooms.
u. Replacement or relocation of water, sanitary sewer, and storm sewer mains and other components.
v. Repave asphalt parking lot and drives within the construction area.
