maximum life. c. The following values shall be used in the absence of approved

manufacturer-specified values. (1) Sealer (Concrete Surfaces)



(a) Number of finish coats: 2 (self-priming coatings) (b) Minimum coat thickness: 11.8/10 mil (wet/dry) (c) Maximum coat thickness: 23.5/20 mil (wet/dry)

(2) Epoxy (Steel Surfaces) (a) Number of finish coats: 2 (self-priming coatings) (b) Minimum coat thickness: 11.8/10 mil (wet/dry) (c) Maximum coat thickness: 23.5/20 mil (wet/dry)

D. Curing 1. Cure time shall be determined by manufacturer specification, based on

local environmental conditions continuously monitored and logged near the project site.

2. NOAA site EBSW1 shall be used to track local weather conditions unless an alternate source of data is agreed upon by Contractor and Port of Seattle.

3. Where ‘minimum’ cure times are published separately from ‘suggested’ cure times, ‘suggested’ cure times shall be considered the minimum for this project.

E. Protection 1. Surface Preparation and Cleaning

a. It is expected that after surface preparation and cleaning is complete, the prepared surface is protected from water, salt, dirt, and other foreign materials.

b. If foreign materials reach the prepared surface prior to coating application, the surface is considered unsuitable for coating application. Contractor shall administer the steps necessary, as outlined above, to prepare the surface.

2. Coating a. Curing coatings shall be protected from wind, water, temperature,

insects, and other factors that detract from the performance of the coating.

b. Coatings applied or cured in environments outside of manufacturer published specifications shall be removed and reapplied.

3. Curing a. At times where the local environment is forecasted to be unsuitable

for curing according to manufacturer specification, Contractor shall provide the means necessary to protect the installed coatings for the duration of the curing.

b. Curing coatings shall be protected from water, salt, wind, temperature, humidity, and other deleterious effects.



c. Use heat, temporary enclosures, splash guards, tarpaulins, drop cloths, or other methods necessary to shield completed work from deleterious effects for the duration of the curing.

d. Moisture typically conveyed through deck drains, scuppers, and other methods may be diverted to protect work. When water conveyance methods are modified, Contractor shall provide the means necessary to remove resulting water from the apron.

F. Repair 1. If a small surface requires a ‘touch-up,’ repair, or recoating, the

replacement coating system shall cover no less than a 6”x6” area, prepared and applied in compliance with the requirements of the original installation and manufacturer-specified repair methods. If the element requiring touch-up is less than 12 sq. in., the entire element shall be recoated.

G. Completion 1. Coated structure shall be rust-free at the time of beneficial occupancy, as

defined in contract documents. 3.05 DELIVERY AND STORAGE 3.06 QUALITY ASSURANCE

A. Craft Worker Qualifications 1. The Contractor shall have a written craft worker assessment and

proficiency monitoring program that defines procedures the company uses to initially qualify, train and at least annually evaluate and document the proficiency of all craft workers (i.e., persons performing repairs, surface preparation and coating and lining application) under its supervision The worker assessment program must meet the performance requirements of Mandatory Annex A of SSPC-QP1 and evidence of its implementation must be documented.

2. The program shall contain provisions to administer written tests and/or a hands-on evaluation to assess the skills of new hires that claim to have previous experience, or verify previous qualifications through a formal training or qualification program. Evaluation must include a hands-on skill evaluation using like equipment and products necessary for a complete installation.

3. Documentation of these programs shall be submitted upon request by the Engineer at no cost to the Port.

B. Technical Resources 1. Applicable standards and specifications for coating inspection work are

available to and used by field personnel. 2. The Contractor shall maintain a library of current technical standards (e.g.,

ASTM International, SSPC, NACE International), technical bulletins, publications, product data sheets, MSDSs and other technical references invoked by projects performed.

C. Leadership Qualifications



1. Persons designated by the Contractor to perform quality control inspections in the field must have at least two years field experience in protective coatings and have successfully completed a training course approved by the Port (NACE, SSPC, MPI, or other applicable body). a. The course shall require 24 hours minimum contact time, including

hands-on training and assessment that covers subjects for coating inspection described in ASTM D 3276 applicable to the Contractor’s scope of work.

D. Inspection Procedures and Recording System 1. The Port of Seattle shall be present to inspect structural steel elements to

be coated at each inspection milestone. Steel elements generally include steel shapes, plates, connections, and connector items. a. The Port of Seattle inspector shall be given 24 hours of advanced

notice prior to each milestone. b. Inspection Milestones

(1) Completion of Rough Surface Preparation (2) Cleaning and Completion of Cleaning (3) Primer and Mastic Application and Completion of Application (4) Pre-Coating Surface Preparation (5) Coating Application (6) Protection Methods of each Applied Coating (7) Cured Coating

2. Testing Equipment a. Calibration of instruments used for inspection shall be performed

and documented in accordance with either the equipment manufacturer’s instructions or industry standards.

PART 4 MEASUREMENT AND PAYMENT 4.01 MEASUREMENT

A. “Marine Coating” will be measured as a lump sum (LS) which includes the marine coatings for the existing waterside crane rail beam, existing pile cap, existing bulkhead cap, existing deck panels where noted, new deck panels where noted, and all other related work not specifically described herein but indicated on the drawings. The bid item will include all related materials, labor, and equipment. “D-II” is covered under a separate bid item.

B. “D-II” will be measured as square feet (SF) as indicated on the drawings. The bid item will include all related materials, labor, and equipment.

4.02 PAYMENT A. Payment will be made at the contract lump sum price stated in the Schedule of

Unit Prices for “Marine Coating.” The contract price shall be full compensation for furnishing all materials, equipment, labor and all items required to complete the work.



B. Payment will be made at the contract square foot (SF) price stated in the Schedule of Unit Prices for “D-II.” The contract price shall be full compensation for furnishing all materials, equipment, labor and all items required to complete the work.

C. All other work required to complete the work specified in this section, but not indicated specifically as a pay item, shall be considered a necessary and incidental work.
