Maintenance Dredging of the Winter Harbor Federal Navigation Channel

THIS IS A SOURCES SOUGHT NOTICE ONLY. THIS IS NOT A REQUEST FOR PROPOSALS. THERE WILL NOT BE A SOLICITATION, SPECIFICATIONS, OR DRAWINGS AVAILABLE AT THIS TIME. The Norfolk District, U.S. Army Corps of Engineers, is anticipating a future procurement for a Firm, Fixed Price Construction Contract for Maintenance Dredging of the Winter Harbor Federal Navigation Channel located in Mathews County, Virginia. Description of Work: The U.S. Army Corps of Engineers Norfolk District is seeking qualified and experienced firms capable of performing maintenance dredging of shoaled areas from the Winter Harbor Federal Navigation Channel located in Mathews County, Virginia by hydraulic pipeline method with placement of the dredged material in the Government-furnished shoreline placement area located north of the channel. The base work will include dredging approximately 101,000 cubic yards (CY) of sandy material between Stations 30+00 and 78+00 to a required depth of -6.0 feet mean lower low water (MLLW) with one (1) foot of allowable overdepth, for a total project depth of -7.0 feet MLLW in the pay prism. Optional work will include dredging approximately 29,000 CY of additional sandy material between Stations 30+00 and 78+00 an additional one (1) foot of depth, for a total project depth of -8.0 feet MLLW in the pay prism. The hydraulic pipeline pumping distance from the dredging area to the shoreline placement area will be approximately 9,500 linear feet. Dredging will be required for the full channel width from Stations 30+00 to 40+00 and 50+00 to 78+00, and the full channel width plus a 25-foot overcut from Station 40+00 to 50+00 on the north side of the channel and from Station 42+00 to 50+00 on the south side of the channel to remove a significant shoaled area which is blocking the entrance to Winter Harbor. The project will require the dredging of approximately 101,000 CY of material with an option to dredge an additional 29,000 CY, including estimated accretion to October 2027 and allowable overdepth. The contract is anticipated to be a combination of base work and optional work. The base bid will include mobilization and demobilization of all necessary equipment to perform the work and hydraulic pipeline dredging with direct placement in the unconfined Government-furnished shoreline placement area located north of the channel. The estimated construction price range for this project is between $1,000,000 and $5,000,000. NAICS Code 237990 � Other Heavy and Civil Engineering Construction applies. The Government is not obligated to and will not pay for any information received from potential sources as a result of this synopsis. Construction Time: The construction period of performance will be 120 calendar days from issuance of the NTP. Dredging is prohibited from April 1 to October 31 of any given year due to an environmental time of year restriction. Definitive Responsibility Criteria: This requirement will use Definitive Responsibility Criteria (DRC), which are specific and objective standards established to inform the Contracting Officer, in accordance with FAR 9.104-2. These criteria will be used to assess whether the apparent low bidder can demonstrate the expertise and specialized facilities needed for adequate contract performance. The inability of a contractor otherwise eligible for award to demonstrate minimally acceptable experience as measured by the DRC may result in the Contracting Officer determining the contractor is not responsible. The Definitive Responsibility Criteria will be developed to assess the following work items: Experience in performing a minimum of one hydraulic pipeline dredging job in bay and coastal environments pumping a minimum of 50,000 cubic yards (cy) a distance of two miles or greater within the past five years. Experience in performing a minimum of one job with placement of dredged material within an unconfined nearshore environment (such as beach, surf zone and/or adjacent shallow water areas) sim…
