- Description
- The Bull Lake Spillway Modification project is a complex construction project involving many different construction and engineering disciplines. The project will require excellent communication with the Government and interaction with numerous project stakeholders, including two separate Native American tribal monitors. The construction schedule and sequence of activities is the most critical component for successful completion of the project. Timing and duration of construction activities shall be carefully executed in order to maintain required water deliveries during construction. Summary of Work The principal components of work include: 1. Construction and improvement of temporary access roads 2. Design and installation of an extensive dewatering system 3. Construction of a temporary earthfill cofferdam upstream of the dam across the new spillway alignment 4. Excavation of the new spillway, including the downstream embankment, and placement and compaction of zoned earthfill under the new spillway 5. Construction of a HDPE pipe spillway underdrain system 6. Installation of a secant pile cutoff wall with varying depth from approximately 15 to 30 feet. Tolerances of the secant pile wall include: a. Top elevation of shafts shall be plus (+) or minus (-) 1 inch from the planned elevation b. Wall continuity shall achieve a minimum 6-inch overlap measured parallel to the plane of the wall at all locations along the intersection of primary and secondary shafts c. Shaft verticality of 0.5 percent over the entire depth of the shaft 7. Construction of the new spillway crest structure to include: a. A labyrinth weir with a small slide gate mounted on the weir wall. The labyrinth weir shall be a 10-foot-high, 20-inch-thick wall with a quarter-round shape on top of the upstream face of the wall. The legs of the weir wall shall be angled 8 degrees from the spillway centerline. b. A concrete lined approach channel c. A rectangular concrete chute d. A Type-II, hydraulic jump stilling basin e. An excavated downstream channel leading back to the river f. Installation of the refurbished bridge over the spillway crest 8. Removal of the temporary earthfill cofferdam upstream at the new spillway alignment and installation of new sections of parapet wall and curb. 9. Temporarily relocate the existing truss bridge onto the dam crest near the new spillway. The steel bridge is 103 feet long, 9 feet wide, and weighs approximately 84 kips. Complete refurbishment and repair to the bridge which includes; removing and disposing of radial gate hoists and associated metalwork; removing and disposing of coatings with heavy metals; and removing and disposing of equipment coated with coal tar products. Once repairs are complete, the bridge shall be placed on the new spillway crest and a new concrete bridge deck will be installed. 10. Remove portions of the existing spillway and parapet walls upstream of the dam crest and install soil nail walls. 11. Construction of a temporary cofferdam upstream of the dam at the existing spillway alignment prior to removing and disposing of the existing radial gates. 12. Full width saw cutting of the existing spillway chute, removal of concrete in the upper chute and crest structure, and excavation of embankment adjacent to the existing spillway crest. 13. Foundation excavation below the existing spillway crest, preparation of a new embankment foundation, and construction of zoned embankment, including HDPE toe drains, at the existing spillway crest structure. The Government is looking for potential small business contractors with the specialized experience and resources necessary to successfully complete a project of this size, scope and complexity. The NAICS Code for this project will be 237990, with a small business size standard of $36.5 Million. The Government anticiaptes that we will be issuing a solicitation for Bull Lake around June 2017 and will award January 2018. The estimated range of the project is $25 to $50 Million. The time allowed for completion of work will be 950 calendar days. If a small business believes they are qualified to perform this project, they shall submit a capability proposal demonstrating their ability to successfully accomplish the various components of work for the Bull Lake Spillway Modification project, as described above. Potential contractors shall demonstrate their ability to successfully accomplish the various components of work for the Bull Lake Spillway Modifications project. Potential offerors shall furnish a list (no more than 5) of Federal, State, local government, or commercial projects completed within the last 10 years that are similar in scope and complexity to the work required under this solicitation. The offeror must clearly demonstrate the ability to successfully complete projects in a timely manner, manage a variety of construction disciplines, and work collaboratively with owners. Projects similar in scope and complexity are defined as work involving the following: 1. Design and installation of dewatering systems, control of water after excavation (i.e., unwatering). 2. Completing complex excavation around soil retaining structures. 3. Construction of zoned earth embankments with neat lines transitions from one material to another. 4. Complex concrete work (including cold-weather concrete) similar in nature to construction of labyrinth weirs, spillway chutes. Include experience working with special concrete admixtures used to control concrete properties. 5. Construction of secant pile walls 6. Relocation of and repairing of bridge structures. 7. Completion of complex work within a short time frame, during seasonal weather conditions while maintaining facility operations (i.e., water deliveries). 8. Demonstration of collaborative efforts with the owner to maintain the project schedule.. The following information shall be provided for each project: • Name and location of project. • Description of work. • Note whether or not offeror was the prime contractor and what portion of the work was performed by the offeror and what portion was performed by subcontractors. • Original completion date and actual dates and duration for each project (including modifications). • Initial contract amount and final contract amount (including modifications). • Name, address, and phone number of CO/owner/COR/point of contact who may verify information for this project. • Any problems encountered in performance of the work and corrective actions taken. Failure to provide the detailed information required above will result in the contractor being determined to be incapable of successfully performing this project and will be eliminated from consideration. Capability statements must be submitted no later than January 26, 2017. They shall be sent to gvotobraun@usbr.gov.
