Informational Submittals: Before beginning work, submit the following to the Architect for information. SELECTIVE BUILDING DEMOLITION

2 1. Schedule of Selective Demolition Activities: Indicate the following. a. Detailed sequence of selective demolition and removal work, with starting and ending dates for each activity. Ensure the Owner's on-site operations are uninterrupted. b. Interruption of utility services. Indicate how long utility services will be interrupted. c. Coordination for shutoff, capping, and continuation of utility services. d. Use of elevator and stairs. e. Locations of proposed dust- and noise-control temporary partitions and means of egress. f. Coordination of the Owner's continuing occupancy of portions of existing building and of the Owner s partial occupancy of completed work. g. Means of protection for items to remain and items in the path of waste removal from building. 2. Inventory: After selective demolition is complete, submit a list of items that have been removed and salvaged. 3. Pre-Demolition Photographs or Videos: Submit videos or photographs showing existing conditions of adjoining construction and site improvements, including finish surfaces, that might be misconstrued as damage caused by selective demolition operations. 1.5 PROJECT CONDITIONS A. Intent of Drawings is to show existing conditions with information developed from field surveys and to generally show the extent and type of demolition required. As far as practical, the Owner will maintain conditions existing at the time of inspection for bidding purpose. 1. Make a detailed survey of existing conditions before beginning demolition, and report discrepancies or conflicts between Drawings and actual conditions in writing to the Architect for clarifications and instructions. 2. Do not proceed, when such conflicts or discrepancies occur, before receipt of the Architect's instructions. B. Hazardous Materials: It is not expected that hazardous materials will be encountered in the work. If materials suspected of containing hazardous materials are encountered, do not disturb; immediately notify the Owner. C. Maintain existing utilities indicated to remain in service and protect them against damage during selective demolition operations. Maintain fire-protection facilities in service during selective demolition operations. D. Storage or sale of removed items or materials on-site is not permitted. SELECTIVE BUILDING DEMOLITION

3 1.6 WARRANTY A. Remove, replace, patch, and repair materials and surfaces cut or damaged during selective demolition operations by methods and with materials so as not to void existing warranties. PART 2 - PRODUCTS (NOT USED) PART 3 - EXECUTION 3.1 SURVEY A. Survey existing conditions and correlate with requirements indicated to determine extent of selective demolition required. B. Inventory and record the condition of items to be removed and reinstalled and items to be removed and salvaged. C. When unanticipated mechanical, electrical, or structural elements that conflict with intended function or design are encountered, investigate and measure the nature and extent of conflict. Promptly submit a written report to the Architect. D. Engage a California-registered professional structural engineer to survey condition of building to determine whether removing any element might result in structural deficiency or unplanned collapse of any portion of structure or adjacent structures during selective demolition operations. E. Perform surveys as the work progresses to detect hazards resulting from selective demolition activities. 3.2 PREPARATION A. Site Protection: Protect site work indicated to remain against damage and soiling during selective demolition. 1. Do not begin selective demolition work until temporary partitions, barricades, warning signs, and other forms of protection are installed. 2. Protect trees, plants, utilities, and existing improvements that are not to be removed from injury or damage. Replace damaged landscaping, improvements, and utilities in kind. 3. During demolition, provide safeguards for protection of the public, Contractor's employees, and existing improvements to remain, including warning signs and lights, barricades, and the like. 4. Provide and maintain shoring, bracing, and structural supports as required to preserve stability and prevent movement, settlement, or collapse of construction and SELECTIVE BUILDING DEMOLITION

4 finishes to remain, and to prevent unexpected or uncontrolled movement or collapse of construction being demolished. B. Building Protection: Protect building construction indicated to remain against damage and soiling during selective demolition. 1. Do not begin selective demolition work until temporary barricades and other protection necessary to prevent injury to people and damage to adjacent facilities to remain are installed. 2. Do not allow water to enter wall insulation or roof insulation to remain. Replace insulation when it has been wetted. C. Protection of Utility Services and Building Systems: 1. Maintain utility services and mechanical and electrical systems indicated to remain and protect them against damage during selective demolition operations. 2. Locate, identify, disconnect, and seal or cap off indicated utility services and mechanical and electrical systems serving areas to be selectively demolished. a. Arrange with Campus Facilities Services, Work Control ( ) and Verizon/AT&T to shut off indicated utilities. Give at least 48 hours advance notice. b. If building systems or mechanical and electrical systems are required to be removed, relocated, or abandoned, provide temporary services and systems that bypass area of selective demolition and that maintain continuity of services and systems to other parts of building before proceeding with selective demolition. c. Cut off pipe or conduit in walls or partitions to be removed. Cap, valve, or plug and seal remaining portion of pipe or conduit after bypassing. 3.3 SELECTIVE DEMOLITION A. Coordinate demolition with other trades to assure the proper sequence, limits, methods, and time of performance. Schedule demolition so as to impose a minimum of hardship on the present operation of the facilities and the performance of the work specified in other Sections. B. Conduct selective demolition and debris-removal operations to ensure minimum interference with roads, streets, walks, walkways, and other adjacent occupied and used facilities. C. Demolish and remove existing construction only to the extent required by new construction and as indicated. Use methods required to complete the work within limitations of governing regulations. D. Neatly cut openings and holes plumb, square, and true to dimensions required. 1. Use cutting methods least likely to damage construction to remain or adjoining construction. 2. Use hand tools or small power tools designed for sawing or grinding, not hammering and chopping, to minimize disturbance of adjacent surfaces. SELECTIVE BUILDING DEMOLITION
