STATEMENT OF WORK

BUILDING 002 AUTOMATIC FEEDER STEEL BEAM REMEDIATION

USDA NATIONAL COLD-WATER MARINE AQUACULTURE CENTER

FRANKLIN, ME

February 2, 2021

1. BACKGROUND

Building 002 at USDA’s National Cold-Water Marine Aquatics Center (NCWMAC) in Franklin Maine is staffed by Agricultural Research Service (ARS) scientists and support personnel who manage a national research program to address the cold-water marine aquaculture industry’s highest priority research needs. The NCWMAC Facility cultures all life stages of the Atlantic salmon with research program areas to address genetic improvement, growth and development, health, and sustainable production systems for Atlantic salmon and for cold water marine finfish species.

The NCWMAC raises salmon from eggs (in fresh water), and uses 234 separate 50-gallon culture tanks for rearing Atlantic salmon from the fry stage (a stage when the sac or yolk is gone and the salmon must find food on their own), to the parr stage, to the subsequent smolt stage. At the fry stage, fresh water is used in the tanks. In the parr stage, the salmon grow for 12 to 18 months in brackish water as they transition from living in fresh water to saltwater. At the smolt stage, the fish require salty water. At the smolt stage, fish from each family are sent to an industry collaborator that grows them for 18 months to a harvestable size just prior to sexual maturity.

The facility utilizes robotic fish feeders that travel along a series of steel “trolley rails” that are suspended over the tanks by structural steel framing members. The robotic fish feeders contain metal roller bearings that rest upon the upper surface of the bottom flange of the trolley rail to support the feeders; rubber wheeled drive rollers in contact with the lower surface of the bottom flange that provide motive power to the feeders; and metal thrust rollers that engage with the edge of the bottom flange to guide the feeders around the curves in the trolley rail system.

The trolley system is experiencing premature failure of the existing protective coatings and subsequent rusting of the steel members.

Given the salinity of the water used in the various stages of salmon research the environment to which the steel is exposed the Society for Protective Coatings (SSPC) would be classified as an Environmental Zone 2B (Frequently wet by salt water. Coating may be subject to condensation, splash, spray or frequent immersions.) by the Society of Protective Coatings (SSPC). Based upon the action of the automatic feeder bearing and thrust rollers on the trolley rail the environment would also be considered abrasive.

2. OBJECTIVE

The objective of this project is to remove the existing rust and failed coatings from the automatic feeder trolleys and associated structural steel framing members and install a protective coating system that is suitable for use in an Environmental Zone 2B and is abrasion resistant.

3. SCOPE OF WORK

The scope of this Statement of Work encompasses construction services to efficiently and effectively fulfill the USDA’s goals and objectives. Specifically, the Contractor shall provide the experienced management, skilled labor and acceptable materials to clean the existing robot feeder trolley and structural steel framing systems; prepare the surfaces to receive primer and top coats per the coating manufacturer’s requirements; and install primer and subsequent top coatings per manufacturer’s recommendations and specified thicknesses.

The USDA welcomes alternate solutions for the prevention of abrasion and the subsequent corrosion of the trolley beam from the action of the feeder robot support and thrust bearings through the use of stainless steel, aluminum, or carbon fiber reinforced bearing surfaces.

The Contractor shall be directly responsible for ensuring the accuracy, timeliness, and completeness of all tasks.

The system consists of a steel beam trolley rail that has a 4” deep web and 2” wide top and bottom flanges that supports the automatic feeder robot and guides it along its travel path. The trolley rail is supported by an 8-1/4 “ deep steel I beam with 2” wide top and bottom flanges. The support beam/trolley rail are suspended from the building’s superstructure by a series of 4” diameter steel pipes.

See ATTACHMENT A for photographs of the systems.

The trolley rails are supported approximately 11 feet off the floor. Ceiling height varies by room.

4. SPECIFIC TASKS

4.1 Prior to the start of any construction activities the Contractor shall develop a construction schedule that accommodates the facility’s research schedule, which may require multiple mobilizations/demobilizations. The schedule shall be developed with the Location Coordinator/Facilities Manager (LC/FM) and approved by the Contracting Officer (CO).

a) A separate schedule shall be developed for each feeder rail system and shall include the total time each feeder robot will be out of commission by identifying tasks

· Installation of the Broodstock protection system

· Surface Preparation

· Primer Installation and recommended cure time

· Topcoat Installations and recommended cure time

· Removal of Broodstock protection systems

· Final Cleaning and Demobilization

4.2 Prior to the start of any construction activities the Contractor shall develop a Broodstock Safety Plan indicating how the developing salmon will be protected from the proposed construction activities. The schedule shall be developed with the Facilities/Location Manager and approved by USDA’s Livestock Safety Officer.

4.3 The trolley rails shall be protected with a primer/top coating system designed for performance in a marine environment and subject to wear and abrasive conditions.

4.4 The support I beams, and pipe hangers shall be protected with a primer/top coating system designed for performance in a marine environment but will not be subject to wear and abrasive conditions. Different products are acceptable for each condition.

4.5 Clean and prepare approximately 918 lineal ft of existing steel trolley track; 1,026 lineal ft of structural steel I beams; and 530 of pipe hangers to receive primer and top-coat installations.

a) Clean all surfaces of each steel member including joints, fasteners, attachments and accessories per manufacturer’s recommendations.

b) The Contractor shall only clean and prepare an area of existing steel members that can be primed by the end of the workday or prior to occurrence of flash oxidation, which will be based upon humidity levels present at the time of the cleaning operations.

c) Any flash oxidation that occurs prior to priming shall be removed prior to the installation of the primer coat.

4.6 Install a primer coat to all cleaned members per the coating manufacturer’s specifications and instructions.

4.7 Installed topcoats to properly primed surfaces in the number of coats and thickness required by the coating manufacturer’s specifications and instructions.
