- Description
- The U.S. Army Corps of Engineers, New England District, is issuing a Sources Sought Announcement for the Spillway Slope Stabilization project at the Thomaston and Northfield Brook Dams, both located in Thomaston, Connecticut to determine the interest, availability and capability of HUBZone, Service-Disabled Veteran-Owned, Women-Owned and Small Business concerns as described below. The NAICS code for this procurement is 237990. The project is planned to be issued on or about December 2017. The project will occur in the spring of 2018 and is expected to take about two months, including submittal approval. The estimated construction cost is between $250,000 and $500,000.00. The Thomaston and Northfield Dams are located about five miles apart in Thomaston, Connecticut. Both dams include spillway channels that were constructed from cutting the channels into the underlying bedrock. The bedrock at both dams consists of highly foliated schist, with minor pegmatite and granofels at the Thomaston Dam location. Over time, the cut rock faces have weathered, with rock blocks separating from the channel sides, and falling to the channel bottom below - a height of up to 40 feet at Northfield Brook, and 50 feet at Thomaston Dam. This project is to address unstable rock blocks present on the south side only of the channel at the Thomaston Dam, and the southeast side only of the spillway channel at Northfield Brook. Specific work items included in this project consist of: • Performing scaling operations to loosen unstable rock masses present in the spillway channels of both dams. Scaling and breaking would be accomplished by using hydraulic rock splitting machines, hand tools held by a worker suspended by ropes over the rock face or by large excavators placed on the channel bottom below. • Loosening two large rock blocks enough to allow them to separate from the rock face, and fall to the ground. These blocks pose a safety risk to agency personnel working in the area. One is triangular in shape and is estimated to be about 30 feet by 50 feet, with an unknown thickness. The other is roughly rectangular and is estimated to be about 30 feet by 25 feet by 20 feet thick. A portable drill could also be utilized to install start holes into the large rock blocks so that hydraulic rock splitters could be utilized to break them into smaller more manageable blocks. • Excavating the fallen rock masses once they have fallen to the ground. Disposal will be at a location within the Federal property, and identified by project personnel. • Excavating previously fallen rock and soil presently at the bottom of the rock face, with transportation to the disposal location.   Safety considerations will be of utmost importance as a part of this project, as rock masses could prove to be large and unstable. Access to the upper reaches of the rock channels will require either coming down from above using ropes, reaching up with large equipment from below, or by using cranes. Interested firms should submit a capabilities package to include the following: business classification (i.e. HUBZone, etc.) as well as qualifications and experience in performing the work components stated above. Please include at least one specific example of the firm's experience performing the work requirements stated above. The project must have been performed within the last ten years. Please indicate the team subcontractors that will be used to support the offeror's effort and include their prior experience and qualifications, if subcontractors are planned to be used. Proof of bonding capability is required. Responses are due November 17th, 2017. Responses should be addressed to the U.S. Army Corps of Engineers, New England District, 696 Virginia Road, Concord, MA 01742-2751, ATTN: Lennie K. Mattis ( lennie.k.mattis@usace.army.mil ) Responses are limited to twenty pages. Interested firms shall provide the above documentation in one original form and one copy. The Government will not pay for any material provided in response to this market survey nor return the data provided. This notice is for information purposes only and is not a request to be placed on a solicitation mailing list nor is it a Request for Proposal (RFP) or an announcement of a solicitation. The results of this survey will be considered to be in effect for a period of one year from the date of this notice.
