JOHN DAY DAM DRILLED WATERSTOP REPAIR

This is not a solicitation. This Sources Sought Announcement is for the purpose of identifying firms which are capable and interested in offering a proposal for remediation to the leaking monolith joints using a system as described below, with the attributes as shown in the attached drawing. Monolith joints located within the John Day Dam, as shown on the provided drawing, shall be drilled vertically from the top of the roadway deck into the foundation rock beneath the dam, approximately 175-ft in length. The drilled hole will be approximately 6-in in diameter and straddle the monolith joint. The drilled hole will be cleaned and inspected with a down-hole camera to ensure proper drilling and alignment along the monolith joint. A steel pipe sleeve, or other approved method, will be installed to protect the upper 2 feet of the drilled socket and monolith concrete during cleaning. Remedial waterstop material will be placed into the drilled holes. Cleaning and installation processes are not to have adverse effects on other parts of the powerhouse. The drilled hole will then be capped with a galvanized steel cover. The waterstop system or product must be able to show adequate application to prevent water leakage between concrete monoliths where the original waterstop has failed. The waterstop system or product must be able to maintain water-tightness with a minimum of 75 psi of static pressure and 170-ft of head. The waterstop system or product must provide continuous water-tightness throughout the entire height of the drilled hole. The waterstop system or product must be a flexible material that does not restrict thermal expansion and contraction at monolith joints. The waterstop system or product must be able to maintain water-tightness throughout hydrostatic load cycles and cycles of thermal expansion and contraction; with approximately 5/8-in of total lateral or horizontal movement during these cycles. The minimum service life of the remedial waterstops is 30-years. The product must have been used successfully in a minimum of 3 different projects within the past 10 years with performance criteria that meet or exceed those herein. Information from firms who respond to this announcement by submitting a statement addressing their experience and past performance will be used in the Government's determination of whether to sole source this requirement or open it to competition. Interested parties must respond to this sources sought announcement in writing, indicating their experience (what your firm did) and past performance (how well your firm did it) in performing work of the type described above (no more than 5 projects).
