- Description
- PROJECT TITLE: Weir and Hydraulic Structures Canton Lake Dam, Blaine County, OK. The purpose of this notice is to provide details of the project prior to advertisement of the package. The Government is seeking the best proposals available. To that end, this notice is to make prospective offerors aware of requirements for the proposal stage of acquisition. Background: At Canton Lake, the Government is constructing an auxiliary spillway adjacent to the right abutment of the existing spillway. This auxiliary spillway will be controlled by a weir and nine fuse gates. This auxiliary spillway will be located in the auxiliary channel which is 480 feet wide and has been partially excavated up to the auxiliary spillway location to final channel grade. Vertical diaphragm walls approximately 50 feet tall line the auxiliary channel. The requirements below refer to the next phase of construction. After completion of the below, the final phase will include further excavation to connect the new spillway to the reservoir. Requirement: 1.Placement of a concrete weir (sill) approximately 35 feet deep by 70 feet long and spanning the 480 foot wide channel (approximately 40,000 cubic yards of concrete placement). 2.Concrete water intake monolith approximately 40 feet tall with a 47 by 15 feet base; 3.Concrete intake conduit approximately 11 feet square and 250 feet long. 4.Concrete fusegates, nine each, approximately 30 feet tall and 50 feet wide. It is anticipated that the following services will be required: Structural and mass concrete placement requiring on-site batch plant, formwork, shoring of existing diaphragm walls, excavation, and de-watering. It is the Government's intent to advertise this requirement as a Best Value, trade-off Request for Proposal construction contract. As part of the proposal submission there will be a requirement to submit a comprehensive shoring plan for the existing diaphragm walls. The shoring of the existing diaphragm walls, excavation and subsequent weir construction presents a unique constructability challenges. Offerors should be aware that they will be required to shore the soil beneath the walls during excavation. In addition, the contractor will be responsible for maintaining the structural stability of the walls during the excavation process for both the weir and the conduit. The interactions between the diaphragm wall and soil during phases of excavation are complex and significant analysis will be required. Potential solutions may include but are not limited to: additional anchoring of the existing diaphragm walls, new secant pile or diaphragm wall below (or overlapping) the existing diaphragm walls, piles driven at the edge of the conduit excavation, etc. The Government is looking for contractor expertise and innovation in this area. Attachments to this notice illustrate the final configuration of project features. There are aerial photographs of the site as of January 2011. These attachments to do not constitute final drawings and are for information only. The photographs are intended to orient offerors to the site. Offerors should consider only information given in the RFP package when proposing. The magnitude of this project's price is estimated between $25,000,000 and $100,000,000.
