• <br />Project Expei4ence <br />evaluations of existing facilities, civil design of rehabilitation and /or enlargement of <br />existing facilities and structures, and /or design of new construction. <br />Boyle was selected to provide design and construction services for three fully- automated <br />low -level dams across the North Canadian River for Oklahoma City's MAPS Project. The <br />MAPS Project involves creating an aesthetically pleasing "riverfront" setting along the <br />North Canadian River. The plan, which involves <br />designing an integrated series of lakes, picnic areas, <br />and trails, will provide recreational opportunities <br />along the river through the city. The dams play an <br />integral part in creating the water features along the <br />river. <br />Eastern Avenue Dam, the first phase of the project, <br />involves a 600 - foot -wide gating structure across the <br />North Canadian River. The structure consists of three <br />13 -foot by 100 -foot top- operated hinged crest gates founded on a 4- foot -thick slab. The <br />gate structure will be used to maintain an upstream pool for recreational use. <br />The design of Western and May Avenue Dams, the second phase of the project, involves <br />two roller compacted concrete (RCC) dams with a total of ten 13- foot -high by 50 -foot- <br />wide top- operated hinged crest gates. The dams include two sets of 10- foot -wide by 13- <br />foot -high lock gates. Groundwater pump- back /water quality wells will be used to <br />maintain the groundwater in the city after construction. The dams and the reservoir will be <br />operated and monitored by a SCADA system. The dam design was reviewed and <br />approved by the Dam Safety Section of the Oklahoma State Engineer's Office. <br />Dams and Reservoirs <br />Our team has extensive experience in dams - related work, dating back more than 50 <br />years. This experience encompasses: <br />• New dams, raised dams, levees, detention structures, and tailing dams <br />• Rehabilitation of dams, levees, and canals <br />• Mitigation of environmental impacts of water resources projects. Permitting new <br />dam and dam rehabilitation projects in the federal, state, and local arena <br />• Inspection and evaluation of dams. <br />• Construction phase services for dams <br />A tabular summary of some of our more recent representative dams - related projects is <br />shown in Table 4on the following page. Most of the listed projects have been completed <br />within the past eight years. <br />35 <br />
