Scope of Work: McNary Lock and Dam is located on the Columbia River, near the town of Umatilla, Oregon. The concrete beams are important to the infrastructure of the intake deck as they support the embedded rail system on which the 140-ton Gantry Crane trolleys. The intake deck is located on the upstream side of the dam, spanning north and south direction. The Washington and Oregon State boundary runs east and west down the center of the dam. The north side of the dam is in Washington; the south side of the dam is in Oregon. The upstream rail is support by concrete support beams located underneath the intake deck. The scope will include determining the exact amount of concrete and rebar needed to increase the capacity of each support (48 in total) and construct the enlarged beam section using a form and pump methodology where positive pressure is applied and maintained throughout the curing process. Futher details can be found in the attached solicitaiton package to this notice.
