SECTION C SOW

C000 GENERAL

C001 MISSION STATEMENT

The Philadelphia District (NAP) of the U.S. Army Corps of Engineers (USACE) has issued this Request for Proposal (RFP) to acquire two (2) new identical self-propelled great lakes tugboats. The vessels are intended to serve the U.S.

Army Corps of Engineers, Detroit District in support of its various missions.

The tugboats will be twin-screw diesel-powered vessels with an all-welded steel hulls and deckhouses.

The Contractor assumes complete responsibility for building the tugboats according to this specification, the Contract Drawings, and the documents required to be developed by the Contractor to meet the requirements of this Contract.

Should the Contractor determine at any time that they are unable to fulfill their contract responsibilities, they shall notify the Contracting Officer’s Representative (COR) immediately of the problem experienced and their proposed manner of correction.

C002 VESSEL OPERATION

The two (2) new tugboats, designated the CELRE DETROIT ICE CLASS TUGBOATS, will provide mobilization of various pieces of floating plant on the St. Mary’s River, upper great lakes, and the Soo Harbor, as well as breaking ice up to 12” thick and performing ice scraping operations at the St. Mary’s Falls Canal. The principal missions of the vessels include:

• Towing and pushing various barges on the St. Mary’s River and upper great lakes April through November in minimal ice conditions.

• Pushing barges in the Soo Harbor mid-November through late-January and mid-March through April in significant 1st year broken ice.

• Breaking 1st year ice up to 12” thick occasionally in the St. Mary’s Falls Canal in late-December thru late- January and mid-March thru early-April.

• Scraping ice from St. Mary’s Falls Canal lock chamber walls and miter gates mid-December through mid- January and mid-March through mid-April.

• Handling various barges including:

o Various deck and hopper barges utilized to transport marine construction and dredging materials, up to two inline on tow lines/bridles.

o Excavator barge with dimensions of 170’ of length, 50’ breadth, and an approximate draft of 4’ with up to one (1) deck or hopper barge(150’ x 35’x 4’ draft).

o Crane barges up to 150’ in length and 50’ in breadth, and an approximate draft of 4’ with up to one

(1) deck or hopper barge(150’ x 35’x 4’ draft).

E. WELDERS

All welding under this contract shall be done only by welders who have successfully passed qualification tests accepted by the American Bureau of Shipping or other regulatory agency acceptable to ABS. The Contractor shall bear the expense of conducting these tests and shall certify by name to the Contracting Officer welders who have successfully passed the prescribed tests and hold current, valid certifications.

The listed of certified welders shall be submitted during Phase II of the Contract. The list shall include the employee’s name, certification(s), and date(s) of the most recent tests for each certification(s). This list shall be named and numbered 877-C025-01 LIST OF CERTIFIED WELDERS.

The Contractor shall require any welder to repeat these tests when, in the opinion of the COR, the work of the welder indicates a reasonable doubt of their proficiency. In such cases the welder shall be re-certified as above if they successfully passed the retest; otherwise, they shall be disqualified until they have successfully passed the retest.

The Contractor shall maintain records of the individual welder’s certification during the course of the Contract. The records shall be available for examination upon request of the Contracting Officer or their representative.

F. WELDING

All welding shall be in accordance with the current rules of the American Bureau of Shipping, except where stated otherwise. All welding equipment used on the work shall be of a modern type subject to close control. The electrodes used throughout the work shall be suitable for use with the parent metal at each weld and shall be approved by ABS.

Welding procedures, as to direction, length, numbers, and sequence of beads, shall be carefully planned to minimize lock-up stresses. Care shall be exercised to produce smooth even beads, especially on all exposed plating and fittings.

Beads shall be ground where directed by the Contracting Officer or their authorized representative.

The Contractor shall employ appropriate welding procedures and grounding connections to preclude the possibility of anodic erosion of the hull after launching.

A detailed description of all welding procedures being employed in the construction shall be available to the Contracting Officer or their authorized representative.
