Photograph printer with docking capability compatible with the camera including supplies necessary to print. (i.e. Ink Cartridges, Photograph quality paper, and other consumables required for operation and photograph printing.) B. One Spring micrometer and extra-coarse replica tape on the project at all times. C. One SSPC-PA2 Type 2 (electronic) non-destructive coating thickness gage and two sets of National Institute of Standards & Technology calibration plates. The first set of calibration plates shall be 1.5 to 8 mils (38 to 200 m), Model No. 1362b, and the second set shall be 10 to 25 mils (250 to 625 m) , Model No. 1363b. D.

SSPC Visual Standard for Abrasive Blast Cleaned Steel (SSPC-VIS 1). H. One recording thermometer capable of recording the date, time, and temperature over a period of at least 12 hours. 514.06 Work Limitations. Apply the prime coat to new structural steel inside permanent buildings at the fabricator’s facility. If inside permanent buildings, the fabricator may perform year-round abrasive blasting and painting. Perform abrasive blasting and painting in the field from April 1 to October 31. The Department will not issue a time extension due to adverse weather during the month of April. The plans or other Contract Documents may require additional work limitations for specific bridges or projects. A. Temperature. Except for inorganic zinc, apply paint when the steel, air, and paint temperature is 50 °F (10 °C) or higher and expected to remain higher than 50 °F (10°C) for the cure times listed below. Apply inorganic zinc when the steel, air, and paint is 40 °F (4 °C) or higher. Cure inorganic zinc according to the minimum curing time and temperatures specified in the paint manufacture’s printed instructions. 50 °F 60 °F 70 °F (10 °C) (16 °C) (21 °C) Primer (Organic Zinc) 4 hrs 3 hrs 2 hrs Intermediate 6 hrs 5 hrs 4 hrs Finish 8 hrs 6 hrs 4 hrs Monitor the temperatures listed above for cure times using the recording thermometer. The Contractor may use a heated enclosure or building. Supply heat 366
367 514.07 continuously and uniformly to maintain the required minimum curing temperature within the enclosure or building until the coating has cured. If combustion type heating units are used, vent the units away from the enclosure or building and do not allow exhaust fumes to enter the enclosure or building. Do not use open combustion in the enclosure or building. The fabricator may use radiant heat when painting new structural steel inside permanent shop buildings. Locate radiant heaters at least 10 feet (3 m) above all surfaces to be painted. Vent exhaust fumes to prevent fumes from contacting surfaces to be painted. B. Moisture. Do not apply paint: 1. If the steel surface temperature is less than 5 °F (3 °C) above the dew point. met. 2. If the steel surface is wet, damp, frosted, or ice-coated. 3. If the relative humidity is greater than 85 percent. 4. During periods of rain, fog, or mist unless the above moisture criteria is If steel was abrasive blasted when the temperature of the steel was less than 5 °F (3 °C) above the dew point, reblast the steel when the steel temperature is at least 5 °F (3 °C) above the dew point. 514.07 Protection of Persons and Property. Collect, remove, and dispose of all rubbish, buckets, rags, or other discarded materials and leave the job site in a clean condition. Except for deck bottoms and backwalls which have not been sealed or are not to have a sealer applied, protect all portions of the structure, that are not to be painted from damage or disfigurement by splashes, spatters, and smirches of paint. If the Contractor causes any damage or injury to public or private property, the Contractor shall restore the property, to a condition similar or equal to the condition existing before the damage or injury. 514.08 Pollution Control. Comply with pollution control laws, rules, or regulations of Federal, State, or local agencies and requirements of this specification. 514.09 Safety Requirements and Precautions. Comply with the applicable safety requirements of the Ohio Industrial Commission and OSHA. Provide Material Safety Data Sheets (MSDS) at the preconstruction meeting for all paints, thinners, and abrasives used on this project. Do not begin work until submitting the MSDS to the Engineer. 514.10 Inspection Access. In addition to the requirements of 105.10, furnish, erect, and move scaffolding and other appropriate equipment to allow the inspector and the Engineer the opportunity to closely observe all affected surfaces during all phases of the work and for at least 10 workdays after completely painting each structure to allow for the Final Inspection as per 514.21.
