poy winner – land, $2 million to $5 million Installing sheet-pile scour protection wall along Santa Clara River which varied along the entire distance of the wall. In order to mitigate costs, RLW worked with its supplier, Skyline Steel, to develop a sheet-by-sheet cut plan and provide material at the specifically required lengths. Taking the time to individually layout every sheet and pre-cut them to length netted over $50,000 in savings to the project. During the design process, it was identified that at times the bedrock elevation was not much lower than scour depth. This potentially could have resulted in portions of the sheet pile wall not having the required embedment to withstand a severe flood event. RLW worked with the designers to implement tiebacks at these portions of the wall to provide added stability. The material had to be brought in on an as-needed basis due to the limited workspace and proximity to existing homes and businesses. Furthermore, since every sheet was cut to length, the challenge was to bring out the right sheet for the right place at the right time. RLW worked with Skyline to develop a transport plan wherein each sheet pile was delivered to the project in small increments in the order in which they were to be installed. This greatly reduced the need for on-site storage space. Environmental constraints were significant challenges to the project. The project encroached on the breeding grounds of the southwest willow fly catcher bird. The RLW team went to great lengths to map the sensitive breeding locations and work its schedule around discovered breeding nests. At times, this required the RLW team to skip portions of the wall during installation. Attention to layout became paramount in order to ensure that both sides of these “fill-in” portions of the wall could be interlocked with the previously installed sheets. Additionally, the environmental constraints required continual construction monitoring by various government agencies to ensure Over 84,000 square feet of sheet-pile was installed down to bedrock along the bank of the river that no threatened or endangered species were harmed and that any disturbance to the natural environment was kept to a minimum. Shortly after the construction of the wall, heavy rains caused the second 100-year flood event in a decade. The Santa Clara River again crested its banks to within a few inches of the top of the wall. Neighboring properties and businesses were saved and damage was held to a minimum from the severe erosion of 2005. The completion of the wall was celebrated by city and county personnel as well as the general public. t Brian Tolley is the manager of the Piling and Shoring Division for Ralph L.
