This is an appendix document providing photographic documentation and specifications for multiple concrete and sidewalk repair and replacement projects at Coast Guard Island, Alameda, California.

The appendix details nine distinct work areas requiring concrete construction and demolition services. Area 1 involves demolishing a brick clinic front entrance and replacing it with a concrete entrance across approximately 50'x50'. Area 2 requires demolition of approximately 350 linear feet of rubber sidewalk and replacement with standard concrete sidewalk. Area 3 calls for demolition of existing sidewalk and grass curbing, then installation of new wider concrete sidewalk (approximately 350 linear feet) properly leveled to curb, with notation regarding backflow preventer interference. Area 4 requires demolition and disposal of a covered walkway structure (approximately 160 linear feet of treated timber) and approximately 900 linear feet of asphalt walkway, replaced with concrete walkways. Area 5 involves demolition of approximately 250 linear feet of highly damaged concrete sidewalk, installation of approximately 175 linear feet of new concrete walkways connecting emergency exits, leveling and seeding of remaining 75 linear feet, with contractor responsibility for removing root intrusion while maintaining tree health. Area 6 requires repair of approximately 100 linear feet of sidewalk and parking lot entrance damaged by root intrusion, with contractor responsible for selecting repair methods to remove tripping hazards. Area 7 involves removing garden plantings and filling in approximately 20 linear feet by 1 foot wide sidewalk at Building 14. Area 8 requires repair of up to approximately 50 linear feet of highly damaged sidewalk behind Building 4, addressing root intrusion damage while considering tree health. Area 9 calls for expanding a concrete pad at magazines by approximately 70 linear feet (5-6 feet width) to accommodate forklift operations. The appendix also specifies miscellaneous tripping hazard grinding across the island, including grinding down up to 150 standard hazards (3-6 feet wide) and up to 10 wider hazards (6-15 feet wide), with contractor coordination with technical representatives to identify highest priority repairs.
