Description of Work (physical characteristics):
Howard A Hanson Dam (HAHD) is a flood control and water storage project located on the Green River in Western Washington State. In addition to protecting downstream cities such as Kent, Auburn, Renton, and Tukwila from flood damage, the dam is also located in the drinking watershed for the City of Tacoma.
HAHD has a gated spillway with 2 spillway gates. The spillway is used during extreme flood events to prevent overtopping of the dam. In order to remain operational and meet current guidance, the gates need to undergo maintenance and retrofits. The following items are expected to be completed as part of this retrofit project:
• STRUCTURAL RETROFITS: In-place strengthening of gate main arms and strengthening of gate curved plate-stiffening ribs for a fracture critical structure. Field welding and field bolting will be required for all structural work in accordance with fraction critical design. Field fitting of structural material will be required.
• HOIST MACHINERY REPLACEMENT: Replace the entire hoist machinery system (including motors, brakes, couplers, wire rope drums, gear reducers, load limiting devices, and all ancillary items). Replace existing mechanical platform.
• REPLACE TRUNNION PIN AND BUSHING: Secure the gates, remove the existing trunnion pin and bushing, and install new pins and bushings.
• REPLACE WIRE ROPES AND ATTACHMENT CONNECTION: Remove existing wire ropes and existing gate attachment connection. Install new gate attachment connections, new wire ropes, and individually tension each rope.
• PROVIDE NEW RUBBER SIDE SEALS: Removing existing steel side angles and install new rubber j-bulb seals. Re-surface the existing embedded stainless steel plates, filling with weld and grinding smooth.
• INSTALL NEW GATE ROLLERS: Install (4) new rollers on each gate.
• COATING: Sandblast existing and re-apply new coating to the entire gate structure (including plates, structural steel shapes, bolts, washers, welds, and all other miscellaneous metal parts, hoist machinery, hand rails, and other downstream appurtenances). Protect all concrete in the vicinity of sandblasting from damage or discoloration. Because this dam is within the drinking watershed, containment will be critical. Water shall be kept from being contaminated by spillway gate rehabilitation operations.
• ELECTRICAL RETROFITS: Replace the entire control system associated with each gate with a new control system to include but not limited to control cabinets, control switches, wiring, control devices, and provide other electrical work required to support the new hoist equipment.
The magnitude of construction is estimated to be between $5,000,000 and $10,000,000. The resulting contract will be firm-fixed-price.
