The New York District plans to award a modification to an existing construction contract for Bridge Work, Physical Security/Safety Improvements in FY20. This notification serves three (3) purposes: 1. To notify potential bidders of the Government’s intent to solicit the following brand name or equal components for this project. 2. To identify potential sources that can provide an equivalent to the listed brand name items. 3. Notification of the intent to solicit brand name or equal components as described below: a. The items described below, under summary of requirements, are embedded in the subject construction project. The work will be issued as a construction contract modification. The components described below will be brand name or equal. In the event no equivalent sources are found, the brand name or equal justifications will be issued pursuant to DFARS 211.104 Use of Brand Name or Equal and DFARS 206.302-1 Only One Responsible Source. A subsequent market survey will not be published in support of a Justification and Approval for sole sourcing. Supplies of the brand name or equal components will be provided directly to the Contractor(s) and not to the Government. b. Summary of Requirements: i. Wipe Rope and Fittings (1) Wire rope and fittings on this project are to replace existing bridge suspender ropes. Three manufacturers are listed within the specifications from who the customer has samples of work from previous projects. These manufacturers are listed only as a standard of quality and the contractor may submit others as deemed appropriate, to be approved by the COR based on the salient characteristics of the wire rope. (2) The following manufacturers are listed in the project specifications. (a) Wireco, Prairie Village, Kansas (b) Wire Rope Works , Williamsport, Pennsylvania (c) Bridon Bekaert The Rope Group USA, Wilkes-Barre, Pennsylvania (3) The salient characteristics of the wire rope are as follows: (a) Rope shall conform to ASTM A603 except where it conflicts with project specifications. (b) Wires shall have Class A galvanizing. (c) The wire strands forming the wire rope shall meet the properties in Table 1 of ASTM A586. Tensile strength and stress at 0.7% extension shall be based on actual cross sectional area of the finished wire, including zinc coating. ii. Caulking (1) The project specifies Sikaflex-1a or approved equal to replace caulking on replaced bridge cable bands. (2) The caulk shall be a one part, non-sag, low-modulus, moisture-cured, polyurethane elastomeric sealant with color to match existing as closely as possible. Salient characteristics for the caulk are as follows. (a) Caulk shall conform to ASTM C 920, Type S, Grade NS, Class 35, use NT, A, M.
