Please identify the painting included in the base bid versus Alternate 1/basement work. In particular, confirm the required extent of restroom ceiling/soffit painting, coves behind glass panels on A-400, and repaired basement CMU walls on AD-103. For match-existing areas, please confirm whether full wall surfaces or only repaired areas must be repainted and how existing colors and sheens will be established.

1. Base Bid vs. Alternate 1 — Painting Scope Summary

All upper-level bathrooms scheduled on A-400 with a GWB/PNT ceiling finish receive new paint as part of the base bid renovation scope.

The basement Storage Room CMU wall: Contractor to partially demo the CMU wall to remove the embedded sanitary pipe, then rebuild the demolished portion and repaint the surface to match existing paint. This CMU repainting is a Base Bid item.

Alternate 1 painting work is limited to the basement Men's and Women's Bathrooms. Contractor to partially demo the front side of the chase to replace the sanitary riser, rebuild the demolished

CMU portion, and repaint the surface to match existing paint. The inside of the bathrooms are also painted in it entirety with matching color paint. Contractor to partially demo the chase CMU wall on the outside of the bathroom, demo and replace the sanitary riser, rebuild the demolished

CMU portion, and repaint the surface to match existing paint. Additionally, under Alt-1, the gypsum board ceilings in the basement Men's and Women's Bathrooms are demolished to access the sanitary piping. Contractor shall replace the demo gypsum ceiling in kind. The replacement gypsum ceiling is to receive paint finish consistent with the standard GWB/PNT ceiling finish called out in the Finish Schedule (A-400).

Restroom Ceiling / Soffit Painting

Per the Finish Schedule on Sheet A-400, the ceiling finish for all bathroom bays (Men's and

Women's, all MBW, MVW, WBW, WVW room tags) is designated GWB / PNT — Gypsum Wall

Board with a Paint finish. This applies to all ceiling surfaces within the renovated restroom areas as part of the base bid scope.

Coves Behind Glass Panels (A-400 / MVW 8)

The cove surfaces behind and adjacent to the tempered glass panels at vanity locations MVW 8

(Men's and Women's) shall be painted as part of the base bid scope. The painted cove is a GWB surface visible behind/through the glass panel. Painting is included in the base bid.

Base bid for CMU walls: The intent is to repaint only the repaired/rebuilt portions of the CMU wall surface, not the full wall. The scope is limited to the area of reconstruction. If blending of the repainted area with the adjacent existing painted CMU surface cannot be achieved without visible discontinuity, the Contractor shall notify the Architect for direction prior to proceeding.

Match-Existing — Color and Sheen Verification Protocol

Prior to painting any match-existing area, the Contractor shall:

Field-verify the existing paint color and sheen on the CMU surfaces in the presence of the

Owner's Representative.

Submit a paint sample (minimum 12" × 12" on the actual substrate in the actual location) for

Architect's and Owner's written approval before proceeding.

If the existing paint product is no longer available or cannot be matched within an acceptable tolerance, submit alternate color options to the Architect and Owner for selection. The Owner reserves the right to select a new color for the full wall surface if an acceptable match cannot be achieved, at no additional cost if the repainted area is within the scope noted above.
