Description of Work: 1. The extent of site clearing is shown on the drawings. 2. Site Clearing work includes, but is not limited to, the following: a. Protection of existing trees (if any) b. Removal of trees and other vegetation c. Topsoil stripping d. Clearing and grubbing e. Removing above grade improvements 3. Related Work specified elsewhere: a. Earthwork - Section b. Concrete Work - Section C. Job Conditions: 1. Protection of Existing Improvements: a. Provide protection necessary to prevent damage to existing improvements indicated to remain in place. b. Protect improvements on adjoining properties and on the Owner's property. c. Restore damaged improvements to their original condition, as acceptable to parties having jurisdiction PRODUCTS: Not Applicable. A. Site Clearing - General: 1.

2 C. Disposal of Waste Materials: Burning on Owner's property is not permitted. D. Removal from Owner's Property: Remove waste materials from the site and dispose of as directed by the Architect. END OF SECTION SITE CLEARING 02110/2

3 Section EARTHWORK 1.00 General: A. Existing Utilities: Locate by hand excavation and provide protection from damage. Cooperate with Owner and utility companies for maintaining services. Do not break utility connections without notifying Architect/Engineer a minimum of 48 hours in advance and providing acceptable temporary services. 1. Repair damages to existing utilities as directed by utility company. B. Protections: Protect structures, utilities, sidewalks, pavements, and other facilities in areas of work. Barricade open excavations and provide warning lights. Comply with regulations of authorities having jurisdiction PRODUCTS: 1. Provide bracing and shoring as required in excavations, to maintain until excavations are backfilled. A. Satisfactory soil materials are defined as those complying with ASTM D 2487 soil classification groups GW, GP, GM, SM, SW and SP. B. Unsatisfactory soil materials are defined as those complying with ASTM D 2487 soil classification groups GC, SC, ML, MH, CL, CH, OL, OH and PT. C. Sub base Fill Material: Naturally or artificially graded mixture of natural or crushed gravel, crushed stone, or crushed slag free of vegetation, debris, or other objectionable materials EXECUTION: B. Excavation: Remove and dispose of material encountered to obtain required sub grade elevations, including pavement, obstructions visible on ground surface, underground structures and utilities indicated to be removed. 1. Unauthorized excavation (removal of materials beyond indicated sub grade elevations) may be filled with lean concrete, or corrected by extending indicated bottom elevation of footing to lower elevation, as acceptable to Architect. 2. Stockpile excavated materials where directed, until required for backfill and fill. 3. Excavate for structure to elevations and dimensions shown, extending excavation a sufficient distance to permit placing and removal of other work and for inspection. Trim bottom to required lines and grades to provide solid base to receive concrete. 4. Excavate for trenches to depth indicated or required and to establish indicated flow lines or invert elevations. Maintain uniform width required for particular item to be EARTHWORK 02200/1

4 installed, including width to provide ample working room. Provide 6" to 9" clearance on both sides of pipe or conduit. Outside building, excavate trenches for water bearing piping so top of piping is not less than 3' -6' below finished grade. 5. Cut ground under pavements to comply with cross-sections, elevations, and grades indicated. B. Backfill and Fill: Place and compact acceptable soil material in layers to required elevations. Use soil material free of clay, rock or gravel larger than 2" in any dimension, debris, vegetable matter, waste, and frozen materials. Use sub base material where indicated under piping or conduit; shape to fit bottom 90 degrees of cylinder. 1. Backfill excavations as promptly as work permits. 2. Prepare ground surface to receive fill by removing vegetation, debris, unsatisfactory soil materials and obstructions. Scarify as required so that fill material will bond with existing surface.. 3. Place backfill and fill materials in layers not more than 8" in loose depth, compacting each layer to required maximum density. Do not place materials on surfaces that are muddy, frozen, or contain ice or frost. C. Compaction: Compact each layer of backfill and fill soil materials and the top 12" of sub grade for structures, slabs, steps and pavements to 95% maximum density for cohesive soils and 95% relative density for cohesion less soils. 1. Contractor to engage the services of a Soils Engineer to approve fill material, observe, test and certify compaction of fill. Test results and certification shall be sent to the Architect. D. Pavement Sub base Course: Place sub base material in layers of indicated thickness, over sub grade surface to support walks and pavement. Place single layer for course 6" thick or less and equal layers for courses more than 6" thick. Compact each lift. E. Grading: Grade areas indicated, including adjacent transition areas, with uniform levels or slopes between finish elevations. Shape surface of areas to within 0.10' above or below required sub grade elevation, compacted as required. F. Maintenance: Repair and reestablish grades in settled, eroded, rutted, or otherwise damaged areas. In damaged compacted areas, scarify surface, reshape, and compact to required density prior to further construction. G. Disposal: Transport acceptable excess excavated material to designated soil storage areas on site, stockpile or spread as directed. Remove and dispose of unacceptable excavated material, trash, and debris from site. END OF SECTION EARTHWORK 02200/2
