D.Quality Control Plan E. Quality Control Inspector (QCI) qualifications
506.04 General Specifications Specifications for the protectiv e coating and/or protective
coating systems are: Zinc Rich Coating System Subsections 506.10 through 506.19 H o t - D i p G a l v a n i z i n g S u b s e c t i o n s 506.20 through 506.29 T h e r m a l S p r a y C o a t i n g S u b s e c t i o n s 506.30 through 506.39 Fusion Bonded Epoxy Coating Subsections 506.40 through 506.49 506.05 Inspection Quality Control (QC) is the responsibility o f the Contractor. Inspect all aspects of the work and supervise all sampling, measurement s and testing. Record measurements and test results in a clear and legible manner in a format acceptable to the Fabrication Engineer. Reject mat erials and workmanship that do not meet Contract 5-89 requirements. The QCI may perform sampling, measurements and t esting in addition to the minimum required. Make the results of all sampling, measuremen ts and testing available to the Quality Assurance Inspector (QAI). Training in surface preparation, coatings application, and insp ection is required for QCI’s. Acceptable training includes one or more of the followi ng:
A.National Association of Corro sion Engineers (NACE) Internati onal: Coating Inspector Program Level 1 (minimum)
B.SSPC BCI Coatings Inspecti on Training and Certification for the Bridge Industry: (Level I without certification), or Level II
C.Other training that is acceptable to the Department. Quality Assurance (QA) is the prerogative of the Department. T he QAI’s responsibility is to ensure that the QC personnel are performing acceptably, v erify documentation, periodically inspect workmanship and witness sampling, measurem ents and testing. The QAI will schedule measurements and testing deemed necessary by the Resident in addition to the minimum requirements in a manner that minimizes interfer ence with the production schedule. The QAI has the authority to reject material or workmanship tha t does not meet the Contract requirements. The acceptance of material or workmansh ip by the QAI will not preclude subsequent rejection, if found unacceptable by the Dep artment.
506.06 Non-Conforming Work Submit a non-conformance report to the Fabrication
Engineer describing the defici encies and proposed solution. Co rrect or replace rejected coatings as directed by the Fabrication Engineer.
506.07 Facilities for Inspection Provide a private office at t he fabrication plant for the
Department’s inspection personnel, or QAI’s. The office shall be in close proximity to the work. The office shall be climate controlled to maintain the t emperature between 68° F and 75° F and have the exit(s) closed by a door(s) equipped with a lock and 2 keys which shall be furnished to the Inspector(s). The QAI’s office shall meet the following minimum requirem ents: Description Quantity Office area (minimum ft2) 100 Drafting Table Surface (ft2) 3 5 Drafting stools-each 1 O f f i c e D e s k 1 Ergonomic Swivel Chairs 1 Folding Chairs 2 High-speed internet connection (ports) or wireless 1 Fluorescent Lighting of 100 foot-candles minimum for all work a reas 2 5-90 110 Volt 60 Cycle Electric Wall Outlets 3 W a l l C l o s e t 1 Waste Basket with trash bags 1 B r o o m 1 D u s t p a n 1 Water Cooler 1 Cleaning materials-floor, surf aces, windows- for duration of th e project The Contractor will be responsib le for disposing of trash and s upplying commercially bottled water for the water cooler. The QAI has the option to reject any furniture or supplies prov ided to the QAI’s office, based on general poor condition. Provide parking space for the QAI(s) in close proximity to the entrance to the QAI’s office. Maintain the pathway betw een the parking area and the QAI’s office so that it is free of obstacles, debris, snow and ice. The facilities and all furnishings shall remain the property of the Contractor upon completion of the Work. Payment for the facilities, heating, l ighting, telephone installation, internet connection, basic monthly telephone and internet charg es and all furnishings shall be incidental to the Contract. Failure to comply with the above requirements will be considere d denial of access to the Work for the purpose of inspection. The Department will reject all Work done when access for inspection is denied.
506.08 Applicator Qualification Shop-applied paint systems sha ll be applied by
applicators that hold a current A ISC Sophisticated Paint Endors ement (SPE) or are qualified in accordance with NACE NIICAP. Thermal Spray Coating (TSC), i ncluding sealers and top coating shall be applied at facilities with a minimum of fi ve years’ experience with additions of the certifications in the previous section or qual ified in accordance with SSPC- QP6, Contractor Metallizing. Fusion bonded coatings and hot-di p galvanizing shall be applied in facilities with a minimum of five years’ experience of satisfactory performance. The Fabrication Engineer may accept other shop qualifications b ased on experience and/or an audit by the Department.
506.09 Inspection Measure and record the following, as applica ble to the coating
application, in a Job Control Record (JCR):

C.Coating batch and/or lot number, date of manufacture and she lf life.
D.Mixing/thinning. E. Dry Film Thickness (DFT) for each coat. 5-91
F.Cure data-time/temperature/relative humidity.
G.Final inspection and acceptance by the QCI. Submit the format for the JCR to the Fabrication Engineer for r eview prior to beginning application of protective coating. Provide work area illumination as follows: Work Area Illumination Requirements in Foot Candles Description of Work Minimum Recommended General Work Area Illumination 10 20 Surface Preparation and Coating 20 50 Inspection 50 200 Provide a light meter that measures illumination in foot candle s. Use SSPC-VIS 1, Guide and Reference Photographs for Steel Surfaces Prepared by Dry Abrasive Blast Cleaning or SSPC-VIS 3, Guide and Reference Photographs for Steel Surfaces Prepared by Hand and Power Tool Cleaning as required in order to determine acceptable surface cleanliness. Measure and record the environmental conditions during applicat ion and during the entire curing cycle. Failure to provide accurate and complete environmental data may result in rejection of the coating or an extended cure time as determi ned by the Fabrication Engineer. Measure and record the DFT of each coat in accordance with SSPC-PA 2 , Measurement of Dry Coating Thickness with Magnetic Gages (PA 2). ZINC RICH COATING SYSTEM
