e. Structural steel repair for deteriorated sections of Z-purlins can be accomplished by one of two methods, depending on contractor preference. The first method can be to replace the entire length of the deteriorated purlin between the two roof structural supports. The length of purlin material should include the material for appropriate lapping of adjacent purlins meeting at the same roof structural support members. The second repair method can be to sister a length of Z-purlin material against the deteriorated Z- purlin section. The new Z- purlin material shall be identical to the existing purlins in all manners to include thickness, type steel, structural shape, etc..

The contractor shall provide to the Government for approval, the length of new Z-purlin that will be installed alongside the deteriorated purlin and provide an appropriate connection system substantiated by steel building manufacturers. Z-purlin installation and connection to roof panels shall follow initial construction plan requirements. All aspects of surface preparation and painting of deteriorated purlins shall be accomplished first if the repair method chosen will be to sister a section of new purlin material against the deteriorated section of a Z- purlin. The contractor shall take all precautions during installation of new Z-purlin material such that the existing building roof will not leak after the Z-purlin has been installed. The contractor is required to price in his cost proposal the installation of up to 180 lineal feet of similar new

Z-purlin material to replace deteriorated Z-purlin sections.

f. For B-6101, upper sections of gutter down spouts get replaced with new ones that provide a continuous downward gutter slope from the gutter to the vertical downspout piping. Additionally for B-6101, all gutter outlet connection systems from the gutter to the upper downspout piping shall be replaced.

g. At the completion of each paint product application for each building there will be an inspection witnessed by a Government inspector which indicates on site mil coating coverage. The paint coating inspection test for each building will be for five random locations identified by the Government. These locations can be high or low on the building so availability of man lift equipment is required. Submit any questions through the RFI process to the Government contracting agency if any questions arise during construction. The Government shall provide responses as appropriate. The contractor may elect to apply paint products by hand or with appropriate spray equipment, however shall follow the appropriate manufacturer data and Specification Section requirements.

In all cases follow manufacturers recommendations. Allow surfaces to cure a minimum of 30 days before painting.

3.5 APPLICATION

3.5.1 Coating Application

Painting practices shall comply with applicable federal, state and local laws enacted to insure compliance with Federal Clean Air Standards. Apply coating materials in accordance with SSPC PA 1. SSPC PA 1 methods are applicable to all substrates, except as modified herein.

At the time of application, paint shall show no signs of deterioration.

Uniform suspension of pigments shall be maintained during application.

Unless otherwise specified or recommended by the paint manufacturer, paint may be applied by brush, roller, or spray. Use trigger operated spray nozzles for water hoses. Rollers for applying paints and enamels shall be of a type designed for the coating to be applied and the surface to be coated. Wear protective clothing and respirators when applying oil-based paints or using spray equipment with any paints.

Paints, except water-thinned types, shall be applied only to surfaces that are completely free of moisture as determined by sight or touch.

Thoroughly work coating materials into joints, crevices, and open spaces.

Special attention shall be given to insure that all edges, corners, crevices, welds, and rivets receive a film thickness equal to that of adjacent painted surfaces.

Each coat of paint shall be applied so dry film shall be of uniform thickness and free from runs, drops, ridges, waves, pinholes or other voids, laps, brush marks, and variations in color, texture, and finish.

Hiding shall be complete.

SECTION 09 90 00 Page 19

Touch up damaged coatings before applying subsequent coats. Interior areas shall be broom clean and dust free before and during the application of coating material.

a. Drying Time: Allow time between coats, as recommended by the coating manufacturer, to permit thorough drying, but not to present topcoat adhesion problems. Provide each coat in specified condition to receive next coat.

b. Primers, and Intermediate Coats: Do not allow primers or intermediate coats to dry more than 30 days, or longer than recommended by manufacturer, before applying subsequent coats. Follow manufacturer's recommendations for surface preparation if primers or intermediate coats are allowed to dry longer than recommended by manufacturers of subsequent coatings. Each coat shall cover surface of preceding coat or surface completely, and there shall be a visually perceptible difference in shades of successive coats.

c. Finished Surfaces: Provide finished surfaces free from runs, drops, ridges, waves, laps, brush marks, and variations in colors.

d. Thermosetting Paints: Topcoats over thermosetting paints (epoxies and urethanes) should be applied within the overcoating window recommended by the manufacturer.

3.5.2 Mixing and Thinning of Paints

Reduce paints to proper consistency by adding fresh paint, except when thinning is mandatory to suit surface, temperature, weather conditions, application methods, or for the type of paint being used. Obtain written permission from the Contracting Officer to use thinners. The written permission shall include quantities and types of thinners to use.

When thinning is allowed, paints shall be thinned immediately prior to application with not more than 1 pint of suitable thinner per gallon. The use of thinner shall not relieve the Contractor from obtaining complete hiding, full film thickness, or required gloss. Thinning shall not cause the paint to exceed limits on volatile organic compounds. Paints of different manufacturers shall not be mixed.

3.5.3 Two-Component Systems

Two-component systems shall be mixed in accordance with manufacturer's

SECTION 09 90 00 Page 20 instructions. Any thinning of the first coat to ensure proper penetration and sealing shall be as recommended by the manufacturer for each type of substrate.
