OF PLANNING, ENG. & PERMITS DATE: November 20, 2014 ANDRE V. BITTAS, DIRECTOR Room 215 City Hall ALAN TERRY OGLESBY, NCARB, CITY ARCHITECT THIS ADDENDUM IS DIRECTED TO ALL PRIME BIDDERS, AND ALL OTHERS TO WHOM DRAWINGS AND SPECIFICATIONS HAVE BEEN ISSUED. THIS ADDENDUM FORMS A PART OF THE CONTRACT DOCUMENTS. THE FOLLOWING CONDITIONS TAKE PRECEDENCE OVER ANY CONFLICTING CONDITIONS IN THE DRAWINGS AND SPECIFICATIONS. THE DRAWINGS AND SPECIFICATIONS ARE HEREBY AMENDED IN THE FOLLOWING PARTICULARS CLARIFICATIONS Requests for Information: 1. Question: On drawing C1.01 Note 6 Coordinate with the Water Board for Reinstallation of the meter Why would the existing meter have to be removed? Can it be left in place? Response: If acceptable by the BWWB, the water meter may be left in place. 2. Question: On drawing C1.01 Note 12 The existing Sanitary Pump and Controls shall be removed and replaced in kind. Please provide us with the manufacturer and size. Response: The contractor should verify the make, model of the pump and controls, and familiarize themselves site conditions. 3. Question: The steel columns appear to be straight in lieu of tapered as most pre-engineered buildings. Is the engineer s intention for the columns to be straight? Response: The admin building requires straight leg columns with flush girts. The shed structure can have tapered leg columns with bypass girts. (Note the girts in the shed are suspended from the beam clips upside-down so the girts do not hold as much debris.) 4. Question: Are the metal siding fasteners to be hidden in lieu of exposed, the drawings and specs don t say the same? Response: Exposed fasteners are acceptable. GENERAL 1.

10 E. Paste Wax: As recommended by manufacturer. PART 3 - EXECUTION 3.1 APPLICATION A. Examine substrates, areas, and conditions, with Applicator present, for compliance with requirements for paint application. All exposed surfaces not factory finished or noted to be unfinished are to be painted. B. Coordination of Work: Review other Sections in which primers are provided to ensure compatibility of the total system for various substrates. On request, furnish information on characteristics of finish materials to ensure use of compatible primers. C. Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and similar items already installed that are not to be painted. If removal is impractical or impossible because of size or weight of the item, provide surface-applied protection before surface preparation and painting. 1. After completing painting operations in each space or area, reinstall items removed using workers skilled in the trades involved. D. Surface Preparation: Clean and prepare surfaces to be painted according to manufacturer's written instructions for each particular substrate condition and as specified. 1. Provide barrier coats over incompatible primers or remove and reprime. 2. Wood: Clean surfaces of dirt, oil, and other foreign substances with scrapers, mineral spirits, and sandpaper, as required. Sand surfaces exposed to view smooth and dust off. a. Scrape and clean small, dry, seasoned knots, and apply a thin coat of white shellac or other recommended knot sealer before applying primer. After priming, fill holes and imperfections in finish surfaces with putty or plastic wood filler. Sand smooth when dried. b. Prime, stain, or seal wood to be painted immediately on delivery. Prime edges, ends, faces, undersides, and back sides of wood, including cabinets, counters, cases, and paneling. c. If transparent finish is required, backprime with spar varnish. d. Backprime paneling on interior partitions where masonry, plaster, or other wet wall construction occurs on back side. e. Seal tops, bottoms, and cutouts of unprimed wood doors with a heavy coat of varnish or sealer immediately on delivery. 3. Ferrous Metals: Clean ungalvanized ferrous-metal surfaces that have not been shop coated; remove oil, grease, dirt, loose mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that comply with SSPC's recommendations. a. Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming PAINTING

11 b. Touch up bare areas and shop-applied prime coats that have been damaged. Wire-brush, clean with solvents recommended by paint manufacturer, and touch up with same primer as the shop coat. 4. Galvanized Surfaces: Clean galvanized surfaces with nonpetroleumbased solvents so surface is free of oil and surface contaminants. Remove pretreatment from galvanized sheet metal fabricated from coil stock by mechanical methods. E. Material Preparation: 1. Maintain containers used in mixing and applying paint in a clean condition, free of foreign materials and residue. 2. Stir material before application to produce a mixture of uniform density. Stir as required during application. Do not stir surface film into material. If necessary, remove surface film and strain material before using. F. Exposed Surfaces: Include areas visible when permanent or built-in fixtures, grilles, convector covers, covers for finned-tube radiation, and similar components are in place. Extend coatings in these areas, as required, to maintain system integrity and provide desired protection. 1. Paint surfaces behind movable equipment and furniture the same as similar exposed surfaces. Before final installation of equipment, paint surfaces behind permanently fixed equipment or furniture with prime coat only. 2. Paint interior surfaces of ducts with a flat, nonspecular black paint where visible through registers or grilles. 3. Paint back sides of access panels and removable or hinged covers to match exposed surfaces. 4. Finish exterior doors on tops, bottoms, and side edges the same as exterior faces. 5. Finish interior of wall and base cabinets and similar field-finished casework to match exterior. 6. All exposed fire sprinkler piping, including that in mechanical rooms, shall be painted red. G. Sand lightly between each succeeding enamel or varnish coat. H. Scheduling Painting: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for painting as soon as practicable after preparation and before subsequent surface deterioration. 1. Omit primer over metal surfaces that have been shop primed and touchup painted. 2. If undercoats, stains, or other conditions show through final coat of paint, apply additional coats until paint film is of uniform finish, color, and appearance. I. Application Procedures: Apply paints and coatings by brush, roller, spray, or other applicators according to manufacturer's written instructions PAINTING

12 J. Minimum Coating Thickness: Apply paint materials no thinner than manufacturer's recommended spreading rate. Provide total dry film thickness of the entire system as recommended by manufacturer. K. Mechanical and Electrical Work: Painting of mechanical and electrical work is limited to items exposed in equipment rooms and occupied spaces. L. Prime Coats: Before applying finish coats, apply a prime coat, as recommended by manufacturer, to material that is required to be painted or finished and that has not been prime coated by others. Recoat primed and sealed surfaces where evidence of suction spots or unsealed areas in first coat appears, to ensure a finish coat with no burn-through or other defects due to insufficient sealing. M. Transparent (Clear) Finishes: Use multiple coats to produce a glass-smooth surface film of even luster. Provide a finish free of laps, runs, cloudiness, color irregularity, brush marks, orange peel, nail holes, or other surface imperfections. 3.2 CLEANING AND PROTECTING A. At the end of each workday, remove empty cans, rags, rubbish, and other discarded paint materials from Project site. B. Protect work of other trades, whether being painted or not, against damage from painting. Correct damage by cleaning, repairing or replacing, and repainting, as approved by Architect. C.
