19 -- WEATHER DECK PRESERVATION COATING ON COAST GUARD CUTTER LONG ISLAND (110') SOL DTCG37-00-Q-6SP503 DUE 041300 POC Senior Chief Petty Officer Aubrey Hill @ (310)732-7521 or First Class PO Ken Fong (310)732-7524 E-MAIL: U.S. Coast Guard Integrated Support Command, ahill@d11.uscg.mil or kyfong@d11.uscg.mil. 1. Provide labor and material to replace non-skid coating (weather deck) on the Coast Guard Cutter Long Island in accordance with the specifications below. 2. Important note: All work shall be performed onsite at the U.S. Coast Guard Integrated Support Command facility located at 1001 S. Seaside Ave., San Pedro, CA 90731. Contractor shall comply with all federal, state and local regulations. Work shall begin no earlier than April 17, 2000 and completed no later than April 28, 2000. Specifications 3.4 SURFACE PREPARATION NOTE: The Contractor has the option of using either high-/ultrahigh-pressure waterjetting or abrasive blasting to achieve the required surface preparation standard as described below. 3.4.1 In the presense of the Coast Guard Inspector, measure the surface temperature and the dew point. Ensure that proper temperatures and humidity conditions exist for surface preparation. NOTE: The surface temperature must be at least 5 degree F above the dew point during surface preparation. 3.4.2High-/Ultrahigh-Pressure waterjetting (option 1): 3.4.2.1 Fir high- and ultrahigh-pressure waterjetting, prepare the work area to a WJ-3 visual level in accordance with SSPC-SP 12. 3.4.3 Abraisve Blasting (option 2): 3.4.3.1 Prior to any surface preparation, remove all visible oil, grease, soil, drawing and cutting compounds, and other soluble contaminants from the steel surface in accordance with SSPC-SP 1. 3.4.3.2 Prepare the work area to the equivalent of a commercial blast standard in accordance with SSPC- SP 6. Do not use a blasting material that contains oil or leaves an oil residue on the prepared surfaces. 3.4.3.3 Remove all dust, dirt, blast residue, grease, oil and other contaminants from the entire work area. 3.4.4 Tests/Inspections (to be completed regardless of surface preparation method): 3.4.4.1 In the presence of the Coast Guard Inspector, inspect the condition of the steel substrate over the entire work area. check for cracks, corrosion, or any other deficiencies in the hull plating. Note any discrepancies in a Condition Found Report (CFR). The Coast Guard Inspector prior to application of any coating shall approve surface preparation. 3.4.4.2 In the presence of the Coast Guard Inspector, and for every 100 square feet of work area, take and record three (3) surface profile readings from randomly selected locations. Submit results and surface profile tapes to the Coast Guard Inspector. Upon completion of surface preparation, the surface profile shall be a minimum of 1.0 mils and a maximum of 1.5 mils. NOTE: Waterjetting does not provide any additional anchor profile to the substrate. The use of another surface method may be necessary to provide the proper anchor. 3.4.4.3 In the presence of the Coast Guard Inspector, and for every 500 square feet of work area, take and record the nonvisual contamination level of one (1) radmomly selected location. Use one of the methods listed in Appendix B of SSPC-SP 12. The nonvisual contamination condition shall be a SC-2 level or better as defined inSSPC-SP 12. 3.4.5 Where new paint is to be merged into the existing paint system, provide three inch wide, smoothly tapered boundary from the existing paint to the prepared metal surface. 3.5 COATING APPLICATION 3.5.1 In the presence of the Coast Guard Inspector, measure the surface temperature and the dew point. Ensure that proper temperatures and humidity conditions exist for surface preparation. NOTE: The surface temperature must be at least 5 degree F above the dew point during all coating application. 3.5.2 Coat the prepared surfaces with the primer cpecified below in accordance with the manufacturer's instructions: 2 coasts, 5 mils DFT each, High-Build Epoxy Primer, MIL-P-24647, formula 150 Haze Gray 3.5.3 In the presence of the Coast Guard Inspector, use the dry film paint thickness guage to verify the dry film thickness. 3.6 RESTORE 3.6.1 Ship's force shall apply non-skid and restore all interferences. 3.6.2 Clean the exterior of the cutter so that there is no paint debris or grit on the surfaces in and surrounding the work area. Obtain verification of cleaning from the Coast Guard Inspector. 3.7 Coordinate all inspections with the designated Coast Guard Inspector to minimize production delays. Posted 04/03/00 (W-SN440683).
