Summary of Scope of Work: This project is to remove vegetation and rehabilitate the Gaco cut-off levee segment on the Green River near Tukwila per the plans and specifications provided in the future solicitation. The project levees are located in King County, Washington, near the City of Tukwila. The contractor will be required to perform work to include: -Remove blackberries and approximately 33 streamside shrubs and trees from the levee segments. - Furnish required riprap and fill material to worksites. Some specified rip rap rock can weigh up to 3600 pounds. - Pull back existing sediment, and re-grade slopes of levee to a specified profile. - Place levee fill material in lifts. Compact levee fill to specification standards with compaction equipment. - Mix new riprap with old material, placing rock individually on levee profile and toe to ensure rock is properly keyed. This work will occur in water for approximately 50% of the levee height. - Sourcing and planting 100 willow bundles consisting of six (6) 4ft long willow stakes 10 ft on center, per the plans and specifications provided in the future solicitation. - Water quality monitoring may be required. Some of the work will be performed by excavators in Class I and Class II waters. In these locations where the river is immediately adjacent to the levee, only the bucket of the excavator will enter the water. Waters in this region of the Green River routinely exceed 5 feet/second in velocity. Work must be completed by 15 October due to the increased risk for high flood flows as the typical flood season starts and would require the contractor to have the work completed. All on-site work shall be performed in accordance with the USACE Safety and Health Requirements Manual (EM 385-1-1). The Contractor will be responsible for establishing and managing an effective on-site Safety and Health program in accordance with EM 385-1-1 that will require the development and submission of a comprehensive project specific Accident Prevention Plan for Government acceptance. In addition, the Contractor will be required to develop and submit for Government acceptance an Activity Hazard Analyses, for each phase of work that complies with EM 385-1-1. A Site Safety and Health Officer (SSHO) employed by the prime contractor shall be required for each shift of the contractor's on-site operations. The SSHO shall possess a minimum of 3-years of experience in construction safety on similar projects, and shall have completed the 30-Hour OSHA Construction Safety training within the last 5-years. A Certified Erosion and Sediment Control Lead employed by the prime contractor will choose and install erosion control materials for specific site conditions, as necessary The Contractor will be required to use the Government-furnished Construction Contractor Module (referred to as QCS) of the Resident Management System (RMS) to record, maintain, and submit various information throughout the contract period. QCS is a Windows-based program that can be run on a stand-alone personal computer or on a network. The Government will make the QCS software available to the Contractor after contract award. Levee Rehabilitation Locations: PROJECT NAME: Tukwila Federal Levee, King County, Washington NON-FEDERAL SPONSOR: City of Tukwila LOCATION AND DESCRIPTION: Tukwila Levee is constructed along the left bank of the Green River at the City of Tukwila, Washington. The levee is a complete system approximately 23,900 feet long. In an undamaged state, the levee provides a 100-year level of protection (LOP) to commercial and industrial properties and associated infrastructure. DESCRIPTION OF DAMAGE: Three high water events from end of October through mid-December 2015 damaged the levee at two locations. Near the upstream end of the levee (Site 1, Station 225+00), toe scour has caused a slope failure along approximately 105 LF of the bank. Downstream at approximately Station 178+00 (Site 2), the riverward slope has been scoured to an over-steepened slope of approximately 1H:1V along approximately 600 LF. In the damaged condition, the levee provides a 5-year LOP. PROPOSED REPAIR: At Site 1, repairing the levee in-kind to match the upstream levee section geometry is recommended to restore the levee to the previous LOP. The proposed repair section includes a launchable toe and 2H:1V slope of Class IV riprap backed by quarry spalls. The work is anticipated to not remove the log jam, and work will be above the water line within the levee prism. At Site 2, a buried toe will be re-established, and the riverward slope will be restored at 1.5H:1V and armored with Class IV riprap backed by quarry spalls. At both sites, repairs will occur within the pre-damage footprint. Total construction length, including transitions, will be approximately 130 LF at Site 1 and 600 LF at Site 2. Sourcing and planting 100 willow bundles consisting of six (6) 4ft long willow stakes 10 ft on center, per the plans and specifications provided in the future solicitation.
