Store the paint and solvents under cover, out of direct sunlight. Maintain the storage temperature between 40°F and 100°F, unless the r equirements of the manufacturer are more restrictive. Keep all containers of paint unopened until required for use.
587.03 Cons truction Requirements.
The Contractor must submit a copy of current certification in accordance with The Society for Protective Coatings Qualification Procedure No. 1 and No. 2 (SSPC -QP 1 and QP 2). Before work begins, the Contractor must submit a containment plan, a current medical surveillance plan, a lead removal plan, an environmental compliance plan, and a hazardous waste plan. The Engineer will review the plans and approve them before work commences. The Contractor will conduct the work in compliance with all applicable federal, state, and local laws, codes, rules, and regulations regarding lead removal. The Contractor must take all necessary precautionary measures to ensure workers and work areas are adequately protected from fire and health hazards resulting from handling, mixi ng, and applying materials. All damage to sound paint on areas not design ated or authorized by the Engineer will be recoated at no additional cost to the Department and as directed.
A.Surface Preparation . Surface cleaning will be conducted using the following methods:
1.SSPC -SP 1 solvent cleaning to remove oil and grease or other contaminants before blasting.
2.Waterjet according to SSPC -SP WJ -4 or better to remove debris and salts.
3.Abrasive blasting the steel to an SSPC -SP 10 “Near White” before painting, SSPC -VIS 1 will be used in determining the quality of cleaning. All water jetting and blasting operations must be done within containment that prevents release of materials or waste. All wash water and debris from water jetting must be filtered through a filter fabric capable of collecting all loose debris and particles. The Contractor will filter visible paint chips and pa rticulates from the water before for Highway Construction Page 465 of 71 5 placing it into the containers. Before disposal, test the water for total toxic metals and provide sample filtration (e.g., through a multi -stage filtration system ending in 5 microns or better if needed) until the water is not classified as hazardous. Do not abrasive blast until the surfaces are thoroughly dry. Ensure adjacent work areas are protected from abrasive blasting. Blasted bare steel must have an average surface profile of 2.5 to 3.5 mils. The blast profile must be angular or jagged rather than peened. The prepared surface profile must be verified using ASTM D4417, Method C. A record of all measurements must be logged and available for the Engineer’s inspection. The Contractor must provide compressed air that is without moisture and oil contamination for operations in which the air may impinge upon the surface. The Contractor will use the white blotter test in accordance with ASTM D4285 to verify the cleanliness of the compressed air. Conduct the test at least once per shift for each compressor system. Sufficient freedom from oil and moisture is confirmed if soiling or discolorations are not visible on the paper. If air contamination is evidenced, the Contractor will examine the work completed since the last satisfactory contamination test and conduct any necessary cleanup or repair. The Contractor will change filters, clean traps, add moisture separators or filters, or make other adjustments as necessary to achieve clean, dry air. The Contractor will not conduct final surface preparation that exposes bare steel under damp environmental conditions or when the su rface temperature of the steel is less than 5°F greater than the dew point temperature of the surrounding air. The Contractor must conduct soluble salt testing as one of the final acceptance tests of the prepared steel surfaces before coating. Test steel surfaces for chloride, sulfate, and nitrate salt contamination before coating. Perform tests on metal loss areas when present. Metal loss areas are areas with evidence of corrosion or pitting. When metal loss areas are not evident, perform tests adjacent to weld areas, if present. Otherwise, select test sites to be representative of the surface as a whole. Test at the rate of 1 test per 1,500 square feet minimum or as Engineer directed in suspected areas . Results must be recorded and submitted for review and compliance. Chloride measurements greater than 5 micrograms per square centimeter are evidence of excessive chloride contamination. Sulfate measurements greater than 20 micrograms per square centimeter a re evidence of excessive sulfate contamination. Nitrate measurements greater than 10 micrograms per square centimeter are evidence of excessive nitrate contamination. Areas that are not to specification will be considered non- compliant and must be cleaned by water jetting, allowed to dry, and then retested for compliance. The addition of a soluble salt remover (e.g., CHLOR*RID) may need to be added to achieve final acceptance. The addition of a soluble salt remover to the water jetting must meet the appr oval of the paint manufacturer. After cleaning with a soluble salt remover, the area must be rinsed with potable water to remove any residue. Technical representatives from the paint supplier and soluble salt remover must provide written acce ptance before using the product to reduce salt concentration. Testing of the steel must be conducted with a CHLOR*TEST “CSN” Test Kit, Elcometer 134 CSN Chloride, Nitrate, Sulfate kit or an approved equal. Do not clean in areas adjacent to areas that are being painted. Protect freshly painted surfaces from contamination. Contaminated surfaces must be cleaned to the Engineer’s satisfaction before any subsequent application of paint is made. Thoroughly clean corners, angles, and bolted or rivet ed joints . for Highway Construction Page 466 of 71 5 The surface must meet the specified degree of cleaning immediately before painting. Deficient areas must be recleaned.
B.Containment. Meet the containment specifications of Class 1A and 1W as outlined in SSPC -Guide 6. The Contractor is responsible for containing and disposing waste material generated from paint removal and surface preparation operations within the work area. Do not allow removed or applied coatings to fall into a waterway or contaminate the environment. Make every effort to prevent the escape of any dust or paint that will create an EPA or OSHA violation or may create a nuisance to businesses, residents, and/or vehicular traffic near the structur e. Provi de and maintain adequate ventilation during surface preparation, coating application, and the curing phases of work to adequately remove dust and fumes, prevent injury to workers, and/or accumulate volatile gases. Supply all equipment and materials (e.g., ground covers, rigging, scaffolding, planking, containment screens or tarpaulin materials, HEPA -filtered vacuums) needed to contain all paint chips, abrasive blast media, overspray, drips, and spills . Use materials that are free of loose dust and debris when brought onto the project site. Protect the surrounding environment from all debris or damage resulting from the work. Contain and recover debris generated during cleaning, preparation, and coating operations. Design, construct, and maintain containment systems for operations in accordance with BMPs. The containment system must not cause any damage to the existing structure. Enclose all por tions of the structure to be blasted as specified. The containment system must be able to be removed rapidly in case of high winds. Stop abrasive blasting operations if wind conditions prevent capture of blast rebound and paint residue by the containment system. If there is a question on wind conditions, the Engineer will make the final determination on whether blasting operations will stop and the containment system removed. The containment system must not endanger the safety and health of the workers. Design access to the containment system to prevent any confined materials from escaping. To prevent the weight of the confined materials from causing failure to the containment system, all confined materials must be collected and secured in sealed containers at the end of each daily shift, at a minimum . Confined materials must not escape during transfer from the containment systems to the sealable containers. All confined materials within the containment system must be removed and secured in sealable containers before relocation or removal of the containment system. If the containment system fails or if signs of failure are present, the Contractor must stop work immediately. Work w ill not resume until the failure has been corrected to the Engineer’s satisfaction. If the containment structure is removed after the abrasive blasting operations and before the coating operation, the Contractor will install a drip tarp to prevent spillage of paint into the waterway and ground surface below. Levels of air, soil, and water contamination resulting from surface preparations must meet acceptance standards established by the applicable local, state, and federal regulations. for Highway Construction Page 467 of 71 5 During the operation, all portions of the structure (i.e., superstructures, substructures), slope protection, highway and appurtenances, traveling public, and public and private property must be protected from cleaning operations and paint splatter and overspray by using protective coverings or other approved methods. The Contractor is responsible for all damage the operations cause to persons, vehicles, or property. Provide containment for all pai nt chips, abrasive blast medi a, airborne dust, overspray, drips, and spills. Use approved impermeable or impenetrable cover materials (e.g., tarpaulins, drop cloths) on or above the ground and other surfaces as required. The Contractor is responsible for the recovery of debris from th e covering materials. All areas used for containment and recovery, including all areas over which cover material is placed, must be thoroughly cleaned of all debris before work begins. All containment and recovery areas will be closed to the public and signed appropriately. The Contractor must protect vehicles, structures , buildings, equipment, hardware, fixtures, and other materials from abrasive blast media, paint spillage, overspray, and other damage. In addition to containment materials, the Contractor must use protective coverings, shields, or masking as necessary to protect surfaces that are not designated to receive surface preparation or coating. Maintain all protective coverings during the entire period the work is being performed and remove all coverings upon completion of the work. Do not allow removed material to fall on the ground or in the water. The Contractor will be responsible for the cleanup of any spills of removed material. All cleanups will be done to the Engineer’s satisfaction and at no additional cost to the Department. Immediately suspend cleaning and/or surface preparation operations if the Engineer deems the c ontainment measures to be inadequate. Alter the cleaning and/or surface preparation operations or containment methods to satisfy the specified requirements. Follow all applicable OSHA regulations regarding the installation and daily inspection of scaffolding, platforms, and wire cables. Maintain a daily log of the results of the inspections made each shift and after any occurrence that could affect the structural integrity of the scaffolding or wire ropes. Do not remove the c ontainment structure or begin painting until all abrasive blasted surfaces have been inspected and approved by the Engineer.
C.Painting Structural Steel . The structure must receive a stripe coat of the primer, a full primer coat, an intermediate coat, and a topcoat application. All painting must be in accordance with the written instructions of the coating manufacturer, and with applicable portions of SSPC -PA 1, when those requirements are not in conflict with the Standard Specifications. If there is a conflict between the manufacturer’s technical data and th ese speci fication s, the Contractor will comply w ith this section unless the manufacturer’s requirements are more restrictive. When the manufacturer’s requirements are more restrictive, the Contractor will advise the Engineer of the discrepancies in writing and comply with the more restrictive requirement. The Engineer’s decisi on will be final. The surface must be thoroughly dry and free of moisture, dust, grease, or any other substance that would prevent the bond of subsequent paint applic ations. All protective coatings require certification from the manufacturer, including that the primer coat can be applied at a relative humidity up to 98 percent and a for Highway Construction Page 468 of 71 5 temperature as low as 20°F. Do not paint when the temperature of the air, paint, or metal is below that described in the product technical data sheet, when the air is misty, or when conditions are otherwise unsatisfactory. Only apply paint when the surface temperature is greater than 5°F above the dew point. If condensation is observed on the steel, heat or dehumidify until the condensation is removed and conditions are acceptable to begin painting. After the surface is prepared, apply a brushed- on stripe coat of the primer on all areas (e.g., edges, cor ners, seams , crevices, interior angles, junctions of joining members, rivets or bolt heads, nuts and threads, weld lines, similar surface irregularities). This stripe coat must be of sufficient thickness to completely hi de the surface and must be followed as soon as practical by the application of the full primer coat to its specified thickness. The Contractor must extend the stripe coat at least 1 inch from surface edges. All bare steel must be primed within 12 hours of being blast cleaned and within 24 hours if the steel has been washed. If any flash rusting occurs, it will be removed by blasting to meet the specification before painting. Paint will be applied to the clean surfaces as follows: Table 587.03- 1 – Dry Film Thickness Coatin g Dry Film Thickness (mils) Stripe (Primer) 2 - 3 Prime 3 - 5 Intermediate 3 - 5 Top 2 - 4 The Contractor will thoroughly clean the surface of each coat before the application of the next coat to remove dirt, dust, and other interference material. Ensure the removal of detrimental residue from surfaces (e.g., corners, pockets). Clean the surfaces by brushing, vacuuming, or blowing down with compressed air. Remove any grease or oil deposited on the surface of any of the applied coats by solvent cleaning, in accordance with SSPC -SP 1, before the application of the next coat. Remove and replace any paint that is exposed to unacceptable conditions (e.g., rain, dew) before adequate curing.
D.Methods of Applica tion. The Contractor will apply all coats by the methods shown below, unless the methods recommended by the paint manufacturer are more restrictive. Take steps to control paint overspray, drips, splashes, and spills.
1.Airless or Conventional Spray Application. Use airless or conventional spray as appropriate for the coating material. If c onven tional spray is approved for use, verify that the compressed air supply is clean and dry as determined by the blotter test in accordance with ASTM D4285.
2.Brush Application. Use round or oval brushes. Brush apply the paint using a series of small circles to thoroughly fill in all surface irregularities, and end with a series of parallel strokes to smooth the finish. On vertic al surfaces, brush the final strokes vertically.
3.Roller Application. Select a nap size and roller quality that will properly wet the substrate and produce a s mooth, uniform film and finish. A pply the coating so as to achieve complete and thorough coverage of the surface. for Highway Construction Page 469 of 71 5 4. Daubers. On surfaces that are inaccessible for paintbrushes, use sheepskins or daubers especially constructed for the purpose. Apply each coat only after the previous coat has been allowed to dry as required by the m anufac turer's written instructions, but as soon as possible, to minimize the length of time that the coating is exposed to dust and contamination. Do not allow any coat to remain exposed for longer than the manufacturer’s written instructions for maximum recoat time before recoating. If a coat exceeds the manufacturer’s maximum recoat times for any reason, remove and replace the coating. As an alternative to removing and replacing the coating, the Contractor may use a specialized surface preparation method. If so, the Contractor must provide written instructions from the coating manufacturer (e.g., scarifying the surface) to properly prepare the surface to receive the next coat. The specialized steps must be approved by the Engineer in writing. The Contractor will perform the specialized cleaning or removal and replacement of the coatings at no additional cost to the Depar tment. Apply each coat at the proper consistency to ensure thorough wetting of the substrate or underl ying coat and to achieve a smooth, streamlined surface free of dry spray, overspray, and orange peel. Shadow -through, pinholes, bub bles, blisters, fish eyes, skips, misses, lap marks between applications, runs or sags, or other visible discontinuities in any coat are unacceptable and must be repaired. Thoroughly coat all surfaces, especially hard- to-reach areas and irregular surfaces. When coating configurations (e.g., bolts, rivets), apply the material from multiple directions to ensure complete coverage. Use wet film thickness gauges in accordance with ASTM D1212 or ASTM D1414 to verify the thickness of each coat at the time of application. Apply each coat to the specified thickness. Notify the Engineer of any conflicts between the manufacturer’s recommended dry film thickness and the thickness shown. The Engineer’s decision will be final. Ensure uneven surfac es (e.g., edges, corners, crevices, welds, bolt heads, rivets, fasteners) receive a dry film thickness equ ivalent to that of flat surfaces. Measure the dry film thickness of each coat using nondestructive magnetic dry film thickness gauges. Comply with SSP C-PA 2 for the calibration and use of the gauges, and the frequency of thickness measurements. The dry film thickness must be measured for acceptance using ASTM D1186, Method A or B. If a discrepancy arises about an individual coat thickness or coverage, it will be verified using ASTM D4138, Method A (i.e., Tooke Gauge) when authorized and witnessed by the Engineer. The Tooke Gauge readings will be final in determining the dry film thickness of the coating(s). On areas where the Tooke Gauge is used to determine coating thickness, the test area must be repaired according to the approved repair procedure. Repair to the test area will be done at no additional cost. Apply additional coating of the same type to areas of insufficient thickness. Ensure all repairs blend in with the surrounding surfaces. Unless otherwise directed by the Engineer in writing, remove excessive coating thickness and reapply the affected coat(s). Use an approved wet film thickness gauge during application of each individual coat in conjunction with an approved dry film thickness gauge following subsequent minimum cure times. Paint film thickness for Highway Construction Page 470 of 71 5 measurements must be made and documented after each application. Where thickness measuremen ts fall below the specified minimum, additional applications of paint must be made to meet the thickness required. All coatings must be inspected and approved by the Engineer before the next coating is applied. Apply all coats so as to ensure that they are well adhered to each other and to the substrate. If the application of any coat causes lifting of an underly ing coat or there is poor adhesion between coats or to the substrate, remove the coating in the affected area to adjacent sound, adherent coating, and reapply the material. If adhesion is questionable, conduct adhesion tests in accordance with ASTM D3359 or ASTM D4541 as directed and repair all test areas. The Engineer will establish the acceptance criteria for the testing . Replace all defective coating that is revealed by the testing. Repair of damage and unacceptable coatings will be according to the manufacturer’s written guidelines and these minimum standards. Feather the existing coating surrounding each repair location. Feather for a distance of 1 to 2 inches to provide a smooth, tapered transition into the existing intact coating. Verify the edges of coating around the periphery of the repair areas are tight and intact by probing with a putty knife in accordance with the requirements of SSPC -SP 3. Roughen the existing coating in the feathered area to ensure proper ad hesion of the repair coats. When the bare substrate is exposed in the repair area, properly prepare the surface and apply the coating system to the specified thickness. When the damage does not extend to the bare substrate, repair according to the manufact urer’s written instructions and the Engineer’s approval. Maintain the thickness of the system in overlap areas within the specified total thickness tolerances.
E.Waste Collection and Disposal. Wastes contained in accordance with these Standard Specifications must be disposed of in accordance with SSPC -Guide 7. The Contractor must obtain and provide EPA hazardous waste identification numbers, assigned through DEQ, required for collection, transportation, and disposal of the hazardous waste. The Contractor is fully responsible for proper transport to the designated location. Provide the Engineer all necessary information related to the manifesting, transporting, treatment, and disposal of classified hazardous waste. The Engineer must approve the process and the tracking of the material. It is the Department’s responsibility to ensure proper handling and disposal of this materi al. Waste materials must be contained and collected in an approved area. Temporary storage on the project site, before transport and disposal, will be as if the spent material was hazardous. Storage facilities and containers must meet all state and federal requirements for the storage of hazardous material. The Contractor must institute procedures to prevent spilling of all paint materials. Spills must be cleaned up immediately. All contaminated material, including soil, will b e tested and disposed. All trash generated during the Contractor’s operation that becomes contaminated in any way with hazardous substances will be disposed of as a hazardous material. All spent materials and waste debris will be cleaned up within the containment enclosure daily or before any prolonged work stoppage (e.g., weather interruptions). for Highway Construction Page 471 of 71 5 All spent materials and waste debris will be placed in suitable waste storage containers located on the project site. The waste containers and storage arrangement must be reviewed by the Engineer and must be located to avoid potential traffic or environmental hazards. The Contractor will perform weekly inspection of the stored hazardous waste to ensure storage security. Within 90 calendar days of the removal of waste material from the project site, the Contractor must submit a certificate to the Engineer stating that the material has been disposed of in accordance with SSPC -Guide 7. The Contractor will also provide the Engineer with documentation verifying compliance. The documentation must include information on manifesting, traceability, storage, sampling, testing, shipping, or treatment.
F.Quality Control Inspection s. QC is the Contractor’s responsibility. Perform and document all inspection and testing as necessary to ensure accordance with this specification. QC documentation must include the salt concentrations, surface profile, coating thickness, and paint batch numbers for each coating applied. All documentation must be made available to the Engineer for review before conducting the next step of the operation. A representative from the paint manufacturer must be present at the beginning of painting to ensure proper application techniques are being adhered to and to establish the proper painting parameters.
G.Quality Assurance Inspections. QA is the Department’s prerogative. The Department will perform inspection and testing necessary to verify that an acceptable product is being furnished in accordance with this specification. All cleaning and painting will be subject to quality assurance inspection and approval. Inspections will be made as determined by the Department and the Contractor will provide the necessary means to perform proper inspections.
587.04 Method of Measurement.
The Engineer will measure acceptably completed work by the lump sum.
