DEMOLITION A. General Requirements 1. Clear areas required for access to site and execution of Work, including pavements, structures, foundations, vegetation, trash and debris. 2. Coordinate with Owner the time of day and route to remove demolished materials from premises. 3. Remove demolished materials from site as work progresses. Upon completion of work, leave areas of work in clean condition. 4. Remove all buried debris, rubble, trash, or other material not deemed suitable by the Geotechnical Engineer. 5. Fill all voids or excavations resulting from clearing, demolition, or removal of vegetation with specified fill material. B. Fixture and Equipment Removal: 1. Remove existing fixtures and equipment as identified and shown on drawings and required by Architect. 2. Verify all service connections to fixtures and equipment designated for removal have been properly disconnected. 3. Remove all conductors from conduit at all abandoned circuits. 3.4 EXISTING UTILITY AND BUILDING SERVICES A. Where crossing paths and potential points of interference with existing utility services are shown or can be reasonably inferred from surface conditions or evidence of subsurface systems, such as meter boxes, vaults, relief vents, cleanouts and similar components. 1. Review all contract documents showing crossing paths and potential points of interference. 2. Pot-hole or determine by other means the accurate depth and location of such utilities. 3. Incorporate all costs required to complete work under this contract, including additional trenching, re-routing of existing utilities, and all means necessary to construct work under this contract. 4. No additional cost to the Owner will be allowed for work necessary to accommodate utility conflicts where such crossing paths are shown on contract drawings or can be reasonably inferred from surface conditions or components. 3.5 SITE PAVEMENT REMOVAL A. Remove sidewalk and curb where required for new construction as specified and as indicated on the Drawings. 1. Remove all paving by saw-cutting. 2. Remove concrete paving and curbing at locations shown on drawings. Locate closest adjacent expansion or weakened plane joint to define start of removal or saw-cutting. B. Remove asphalt concrete paving areas where required for new construction as specified and as indicated on the Drawings. 1. Remove all paving by saw-cutting. 2. Remove paving assembly as required to expose subgrade. 3.6 LANDSCAPE AND IRRIGATION SYSTEMS DEMOLITION AND RENOVATION A. Clearing, grubbing, and planting demolition. 1. Remove grass and grass roots to a minimum depth of two inches below existing grade. 2. Remove all shrubs, plants and other vegetation within the area of the work unless designated to remain. Grub and remove all roots of all vegetation to a depth of 24 inches below existing grade. 3. Remove only those trees which are specifically designated for removal, or as shown on the drawings, within the construction area. Remove all stumps. Remove root ball and root systems larger than 1 inch in diameter to a depth of two feet below existing or finished grades, whichever is lower and a minimum of five feet beyond the edge of paving, structure, wall or walkway. 4. Hand cut existing tree roots over 1 inch in diameter as necessary for trenching or other new construction, apply multiple coats of emulsified asphalt sealant especially made for horticultural use on cut or damaged plant tissues to cut faces and adjacent surfaces. Cover exposed roots with wet burlap to prevent roots from dying out until backfilling is complete. 5. Disking and mixing of vegetation, trash, debris, and other deleterious materials with surface soils prior to grading is not permitted. 6. Remove all buried debris, organic material, rubble, trash, or other material not deemed suitable by the Geotechnical Engineer. 7. Fill all voids or excavations resulting from clearing, demolition, or removal of vegetation with fill material in compliance with Section 31 00 00
