59-2.02 PAINTING STEEL SOLDIER PILES59-2.02A GeneralSection 59-2.02 includes specifications for preparing and painting steel soldier piles. Where shown, prepare and paint steel soldier piles under the specifications for painting new structural steel in section 59-2.01. 59-2.02B MaterialsNot Used 59-2.02C ConstructionRepair damaged areas of the undercoat before installing piles. Protect the exposed exterior flange and flange edges of undercoated piles from lean concrete backfill to minimize undercoating repairs. After removing lean concrete backfill, repair damaged or deteriorated undercoat by blast cleaning and repainting with the same inorganic zinc coating as used for the undercoat. Apply final or finish coats after installation and excavation are complete. Caulk open joints between concrete and steel soldier piles with sealing compound or other authorized material.
59-2.02D PaymentNot Used 59-2.03–59-2.05 RESERVED59-3 PAINTING GALVANIZED SURFACES 59-3.01 GENERALSection 59-3 includes specifications for preparing and painting galvanized metal surfaces. 59-3.02 MATERIALSCoatings must comply with either State Specification PWB-174A or with section 91-2.02. 59-3.03 CONSTRUCTIONClean galvanized surfaces by pressure washing or steam cleaning. Roughen galvanized areas after cleaning by abrasive blasting. Use an abrasive no larger than 30 mesh. Do not remove galvanizing. Apply 2 finish coats in at least 2 applications. Apply the 1st finish coat the same day abrasive blasting is performed unless otherwise authorized. Apply the 2nd finish coat after the 1st finish coat has dried at least 12 hours unless otherwise authorized. The dry film thickness of each finish coat must be at least 2 mils. The dry film thickness of all coats must be from 4 to 8 mils. The 2nd finish coat color must match color no. 14090 of FED-STD-595. 59-3.04 PAYMENTNot Used 59-4 PAINTING SIGN STRUCTURES 59-4.01 GENERALSection 59-4 includes specifications for preparing and painting sign structures. Preparing and painting of sign structures must comply with sections 59-2 and 59-3. Instead of submitting proof of the certification complying with SSPC-QP 1, you may submit documentation with the painting quality work plan showing compliance with the requirements in section 3 of SSPC-QP 1. Instead of submitting proof of the certification complying with SSPC-QP 2, you may submit documentation with the painting quality work plan showing compliance with the requirements in sections 4.2 through 4.4 of SSPC-QP 2, Category A. Instead of submitting proof of the certification complying with AISC-420-10/SSPC-QP 3, enclosed shop, you may submit documentation with the painting quality work plan showing compliance with the requirements in sections 5 through 18 of AISC-420-10/SSPC-QP 3.
59-4.02 MATERIALSNot Used 59-4.03 CONSTRUCTION59-4.03A GeneralYou may prepare and paint sign structures before or after erection. After erection, repair any damaged paint. The total dry film thickness of finish coats on contact surfaces of galvanized HS bolted connections (1) must be from 1 to 4 mils and (2) may be applied in 1 application. 59-4.03B Undercoating of Ungalvanized SurfacesBlast-cleaned surfaces must receive a single undercoat consisting of an inorganic zinc coating as specified in AASHTO M 300, Type I or Type II, except: 1. The first 2 sentences of section 5.6 do not apply. 2. Section 5.6.1 does not apply.
59-4.03D Finish CoatsThe exposed area of inorganic zinc coating must receive at least 2 finish coats of exterior grade latex paint. The 1st finish coat color must match no. 24558 of FED-STD-595. The 2nd finish coat color must match no. 24491 of FED-STD-595. 59-4.04 PAYMENTNot Used 59-5 THERMAL SPRAY COAT STRUCTURAL STEEL 59-5.01 GENERAL59-5.01A SummarySection 59-5 includes specifications for coating steel surfaces with a thermal spray coating. 59-5.01B DefinitionsReserved 59-5.01C Submittals59-5.01C(1) GeneralSubmit a certificate of compliance for each shipment of wire feedstock. 59-5.01C(2) Coating Quality Work PlanSubmit 3 copies of a coating quality work plan for thermal spray coating activities. Allow 20 days for the Department's review. Submit the work plan after attending the precoating meeting and include: 1. Names of the coating contractor and any subcontractors to be used 2. 1 copy each of applicable ASTM and SSPC specifications or qualification procedures 3. Materials, methods, and equipment to be used 4. Proof of certification for each thermal spray coating operator 5. Methods to control environmental conditions 6. Methods to protect the coating during shipping, handling, and storage 7. Procedures for containing blast media 8. Examples of proposed daily reports for testing to be performed, including type of testing, location, time, weather conditions, test personnel, and results 59-5.01D Quality Assurance59-5.01D(1) GeneralEach thermal spray coating operator must be certified under AWS C2.16/C2.16M. 59-5.01D(2) Precoating MeetingBefore starting coating activities, conduct a precoating meeting to discuss coating quality work plan requirements. Meeting attendees must include the Engineer and all coating subcontractors. 59-5.01D(3) Test CouponsThermal spray coating operators must prepare 3 test coupons for bend testing before each work shift. Test coupons must: 1. Be 2 by 6 inches by 1/16-inch thick 2. Be of the same material as the surface to be coated 3. Pass bend test requirements before the operator starts production work Bend test coupons under section 6.5 of SSPC-CS 23.00/AWS C 2.23M/NACE no. 12. Coupons must exhibit no cracking with lifting from substrate. 59-5.01D(4) Quality ControlThe Engineer selects the test locations. If repairs are required, retest rejected areas after completing repairs. Test the surface profile of blast-cleaned steel under ASTM D4417, Method C. Perform 3 tests for the first 200 sq ft of blast-cleaned steel and 1 test for every 200 sq ft thereafter. Test blast-cleaned steel for soluble salts before coating. Levels of soluble salts must not exceed 10 μg/sq cm. Perform 3 tests for the first 200 sq ft placed during a shift and 1 test for every 200 sq ft thereafter. Inspect surfaces for visual cleanliness under SSPC-SP 10/NACE no. 2 before applying coating. Test coating thickness under section 6.3 of SSPC-CS 23.00/AWS C 2.23M/NACE no. 12. Perform 1 test for every 150 sq ft of coating and 1 test for each faying surface. Perform cut testing under SSPC-CS 23.00/AWS C 2.23M/NACE no. 12. Perform 3 tests of 3 cuts for every 1,000 sq ft of coating. Surfaces must exhibit no peeling or delamination. Test coating adhesion to steel before applying seal coating. Thermal spray coating must have an adhesion to substrate of at least 850 psi. Perform 3 tests for every 200 sq ft of coating. Repair areas represented by tests failing adhesion or cut testing by removing and reapplying coating.
