trained by the manufacturer of the equipment or material and shall be certified by the manufacturer as authorized to represent the manufacturer in performing the prescribed tasks.

If requested by the COTR, provide written documentation from the manufacturer attesting that the representative is authorized to represent the manufacturer.

4.20.3 The representative shall be considered to be an on-site technical consultant to provide technical advice to the Contractor and the COTR. When specified, the representative is also required to take measurements and conduct inspections.

However, nothing herein shall be construed as relieving the Contractor of the responsibility to satisfactorily perform all required work.

4.20.4 Unless other specifications or procurement documents

specifically state that work is to be performed "as directed by the manufacturer's representative", the representative shall be considered to be an advisor, and the Contractor may deviate from the representative's guidance whenever necessary to achieve satisfactory work, provided that the COTR accepts the proposed deviation. If the COTR refuses to allow the proposed deviation, the Contractor must proceed as recommended by the representative, but in this instance only, the Contractor will be relieved of responsibility for any subsequent rework which can be conclusively shown to have been caused by following the representative's guidance.

4.20.5 Prior to proceeding with work which deviates from the

representative's guidance, submit a Condition Report to the COTR which outlines the guidance provided and the reasons for the proposed deviation. Proceed with the deviation only after the COTR has reviewed the Condition Report and accepted the proposed deviation. Whenever the Contractor deviates from the representative's guidance, any and all increased costs resulting from the deviation shall be borne by the Contractor.

4.20.6 Whenever the manufacturer’s representative is required to be “on-site”, the representative shall be at the work site during all times that work is being performed.

4.20.7 The Contractor shall obtain from each manufacturer's

representative a detail service report which outlines all inspections, observations, and recommendations provided by the representative. If measurements were taken by the representative, a record of the measurements shall be included in the report. Submit a copy of the service report to the COTR prior to completion of the contract.

4.21 Welding and Allied Processes.

4.22.1 Prior to applying any paint or coatings, the Contractor shall verify to the COTR that all surfaces have been properly prepared and that weather conditions are suitable for painting.

4.22.2 Paint shall be applied only when the following conditions exist and can be maintained until the paint has cured:

a. Apply paint only to dry surfaces and when there is no chance of precipitation until after the paint has cured. The temperature of the surface to be painted shall be at least 5 degrees Fahrenheit above the dew point. The dew point can be presumed to be satisfactory if a thin, clearly defined film of water applied to the cleaned surface with a damp cloth evaporates within 15 minutes. Otherwise, the dew point shall be measured prior to painting by taking the dry-bulb temperature of the surface and the wet-bulb temperature at the jobsite.

b. The air temperature and surface temperature must both be a minimum of 45 degrees Fahrenheit at all times, unless a lower temperature is specifically authorized by the paint manufacturer's printed instructions.

c. Painting is permitted only when the humidity is less than 95 percent.

d. In the event the Contractor desires or must proceed with painting when the existing weather conditions do not meet the above specified conditions, the Contractor shall erect a cover over the surfaces to be painted and shall heat the surfaces and the surrounding air to establish the required conditions. The conditions shall be maintained until the paint has fully cured.

4.22.3 Restore all existing coating systems which are damaged during performance of work. The new coating system shall be same as existing. New materials shall be painted only if so specified in the detail specifications or other procurement document.

4.22.4 Surface preparation and paint application shall be in

accordance with applicable NOAA Standard Specifications. In event no applicable NOAA Standard Specification exists, comply with the paint manufacturers' printed recommendations and instructions for all aspects of surface preparation, and handling, mixing, and application of paint materials.

4.22.5 Surface preparation and painting of shell plating and

frames below the Load Waterline shall be accomplished only while the ship is in drydock, unless otherwise and specifically authorized.

4.23 Electrical. All requirements and recommendations of

references 2.c and 2.d shall be followed in the selection and installation of electrical cables, equipment, and machinery.

4.24 Piping.

4.24.1 Materials for new installations and new materials

required for replacement of existing piping shall comply with the requirements and recommendations of reference 2.b. and MIL-STD-

777. In the event a conflict between reference 2.b and MIL-STD- 777, the more specific and restrictive shall take precedence.

4.24.2 When renewing existing piping, new piping shall be same material, shall be installed in same configuration, and shall be installed using the same methods and details as the existing piping, unless otherwise specified.

4.25 Tests and Inspections.

4.25.1 At least four hours, but not more than 24 hours, in

advance of conducting each required test and inspection, notify the COTR in order to allow the COTR the opportunity to witness, or to arrange for another NOAA representative to witness, the tests and inspections. If the COTR or other NOAA representative is not present at the scheduled time of the test or inspection, and if the required four hour advance notification was furnished to the COTR, the Contractor may proceed with the test or inspection.

4.25.2 All tests and inspections shall be witnessed by the

Contractor's supervisor responsible for the work. A Condition Report (See 4.1 ) shall be prepared to document the results of all tests and inspections.

4.25.3 In the event a required test or inspection will be

performed at a location other than the ship or the Contractor's facility, the Contractor shall provide round-trip transportation for the COTR to and from the inspection site.

4.25.4 To the extent possible, all tests and inspections shall be scheduled during the normal weekday work shift. Tests and inspections may be scheduled for other times only when necessary to avoid a delay in the contract completion. When necessary to schedule a test or inspection after the normal day shift or on a weekend, the COTR shall be notified of the test or inspection at least four hours before the end of the last preceding regular work shift.

4.25.5 Perform an operational test of all newly installed, overhauled, and repaired equipment to demonstrate proper operation. Shipboard equipment will be operated by ship's crew.

4.25.6 Nondestructive tests (NDT) are required only to the

extent specified in other specifications or procurement documents. When NDT is required, comply with MIL-STD-271F, including the requirements for qualification of NDT personnel, procedures, and equipment. For purposes of this requirement, NDT is defined as the following types of test methods:

a. Radiography (RT)

b. Magnetic Particle (MT)

c. Liquid Penetrant (PT)

d. Ultrasonic (UT)

e. Eddy Current (ET)

4.25.7 Workers performing NDT shall be certified as Level two craftsmen by the American Society for Non-Destructive Testing in accordance with Recommended Practice No. SNT TC-1A. Copies of the worker's certificate shall be provided upon request to the

COTR.

4.25.8 NDT inspection acceptance standards shall be as specified in MIL-STD-2035(SH).

4.25.9 Whenever UT methods are specified for thickness gaging, the following procedures and requirements apply:

a. Prepare the steel surfaces as required to obtain accurate UT thickness readings. After readings have been taken, restore coating systems to that which existed before the surfaces were prepared.

b. The results of the UT thickness gaging shall be recorded as follows:

1. Prepare a table which lists for each gage reading the location, actual thickness, original thickness, percentage of wastage, and recommendations(if any).

2. Prepare schematic diagrams of the shell plating, decks, bulkheads, and other structural members which reflects the approximate location of each reading and the actual reading obtained at each location.

c. Submit tables copies of table and diagrams to the COTR.

d. Except for removal and restoration of coatings, or unless otherwise specified in the Detail Specifications, removal and restoration of deck coverings, insulation, and other interferences are not required in order to take UT readings.

4.25.10 Whenever a "hose test" is specified, conduct the test by directing a 50-psig stream of water from a 1-1/2 inch fire hose through an all purpose nozzle at a distance of not more thanten feet from the surface being tested. Direct the stream of water in a manner most likely to disclose a leak and inspect the opposite side of the surface for leaks.

4.25.11 Whenever an "air test" is required, conduct the test by sealing all vents and applying 2 psig air pressure to the specified tank or compartment. After the 2 psig pressure is attained, disconnect the air supply and monitor the pressure in the tank or compartment with a calibrated pressure gage for ten minutes. If the pressure drops below 1.9 psig during the ten minute period, increase the pressure to 2 psig and inspect for leaks by applying soapy water to all new welds, and to all manhole covers of the tank or compartment. After the test, insure that all vents are unsealed.

4.26 Fuel Oil and Lube Oil Offloading.

4.26.1 Whenever the Contractor is required to or elects to

offload fuel oil or lube oil from the ship, the oil shall be pumped to and stored in clean moisture-free storage tanks. Meter the oils with a calibrated meter during offloading and during return. Take test samples during offloading and during return, and have the test samples analyzed by a lab for water and impurities to verify that the oils were not contaminated while in the Contractor's possession. Provide copies of lab reports to the COTR.

4.26.2 After all work which necessitated the oil's removal has been completed, return the oil to the ship. In lieu of storing the oil, the Contractor may accept title and responsibility for disposal of the oil and provide an equal amount of new clean oil, same as that removed. Test samples are required, even if this option is exercised by the Contractor.

4.27 Disposal of Water. Whenever work requires that equipment, machinery, piping, or tanks be drained of water, the Contractor shall be responsible for draining and proper disposal of the water. If the Contractor drains the water into the ship's bilges, the Contractor shall pump all water from the applicable bilges into dockside tanks and properly dispose of the water, including the water that existed prior to and the water that accumulates between the time the equipment, machinery, piping or tanks were drained and the time the bilges have been pumped dry by the Contractor.

4.28 Work at Government Facilities. The following requirements and provisions apply only when the Contractor performs work at a Government shore facility.

4.28.1 Restrictions.

a. The Contractor will not be permitted to use the Government facility's waste disposal containers for disposal of scrap, waste or any other materials. If the Contractor desires to bring a waste disposal container onto the facility, the container shall not be larger than eight cubic yards capacity.

Only one container will be permitted.

b. Contract work on more than one ship may be in progress concurrently at the facility. Therefore, pier space and parking space may be scarce. Ample pier space will be provided for the Contractor to perform the required contract work. However, the Government reserves the right to prohibit or limit the number of vehicles permitted onto the facility and to specify the permitted parking locations. All vehicles being brought onto the facility will be required to apply for a vehicle pass.

4.28.2 Government-Furnished Services.

a. The Government will provide adequate electric service either on the ship or on the dock for the Contractor to operate equipment and tools necessary to accomplish the required work.

The Contractor shall be responsible for making all electrical connections and for providing all cables, plug, adapters, and other materials for making the connections.

b. The Government will provide water service to the Contractor for use in performing the required work. The service will be limited to that which can be provided by the Government's installed equipment and does not include providing of any hoses or fittings.

c. If the ship on which the work is being performed has operable installed cranes, the ship will provide crane service to assist the Contractor in lifting materials to and from the ship during the first three days of the contract performance period.

The service provided will be limited to the capacity and reach of the ship's crane(s) in its existing condition. The crane will be operated by ship's personnel. Crane service will be limited to the handling of materials which exceed 100 pounds and which cannot be easily carried by the workers. The Contractor shall coordinate and schedule the crane service to minimize the number of lifts required. At least four hours advance notice shall be given to the COTR of the need for crane service.

4.29 Water Depths and Height Restrictions. Whenever the

contract work is to be performed at the Contractor's facility, the government is responsible for transferring the ship to the facility, unless otherwise specified. In addition to the contract clauses included in the bid solicitation, the following restrictions and requirements apply.

4.29.1 At no time will the ship be moored at any dock or transit any waterway which has a water depth less than that required to provide a minimum clearance of one foot under the lowest underwater projection.

4.29.2 The minimum liquid load, drafts and displacement of the ship at which the government intends to transit and arrive at the Contractor's facility will normally be provided in the detail specifications. Also included will be information concerning any changes in the ship’s liquid load which the Contractor will be permitted to make in order to meet the minimum underwater clearance requirements.

4.29.3 At no time will the ship transit a waterway which has

non-opening bridge or other overhead structure that would cause less than one-foot clearance over the ship's highest projection.

In order to permit passage of the ship under bridges or other overhead structures in the waterway, the government will lower masts which have hinged connections for that purpose. However, the government will not remove, and will not permit the Contractor to remove, any part of the ship's structure or equipment for the purpose of providing the required overhead clearance.

4.30 Ship's Moorings. Whenever the contract requires work to be performed at the Contractor's facility, the Contractor shall provide adequate pier or dock space acceptable to the Contracting Officer for safely mooring the ship. The following requirements and restrictions apply:

4.30.1 The facilities and services shall be sufficient to

permit the Contractor to comply with all other requirements of the contract.
