PROJECT DESCRIPTION
THIS PROJECT ENTAILS EXTERIOR MASONRY REPAIR AND MAINTENANCE AT 129 E.
MAIN STREET, NORRISTOWN. THE WORK INCLUDES RAKING, REPOINTING, AND
CLEANING ALL BRICK MASONRY ELEVATIONS, REPAIR/REPLACEMENT OF
DETERIORATED OR CRACKED BRICK MASONRY UNITS.
ALTERNATES:
DEDUCT ALTERNATE #1: SCOPE OF WORK LIMITED TO PRIMARY ELEVATIONS
BASE BID: RAKE, REPOINT, AND CLEAN ALL BRICK MASONRY AND PERFORM
ADDITIONAL MASONRY REPAIR WORK AS INDICATED ON THE DRAWINGS FOR ALL
FOUR BUILDING ELEVATIONS.
DEDUCT ALTERNATE: BRICK MASONRY AT NORTH AND WEST ELEVATIONS TO
REMAIN AS-IS; NO WORK PERFORMED AT THESE FACADES.
