1 SECTION GRADING 1.0 GENERAL.1 Furnish all labor, material and equipment necessary to complete all Site Work as shown on the Drawings and Specifications.. 2 Excavate to exact line and grade as indicated on the Drawings or as specified. Excavate within vertical planes on lines two (2) feet outside exterior surface of structure. Footing bearing levels shall be smooth, level and on compacted or undisturbed soil. Trenches shall be kept free of water at all times. Bearing soil shall be satisfactory to the Architect. Unauthorized excavation where existing surface levels are lower than subgrade levels required for work, where excess of unauthorized excavation takes place beyond indicated lines, fill at no extra cost to Owner to indicated subgrade as floors. Where footing and foundation occur, use concrete fill of same proportions as specified for footing and foundations. Where slab occurs, use well compacted and clean earth fill. A rock excavation proposal shall be included in the Bid Proposal. Contractor to bid project as a classified site, and shall include all rock and unsuitable soils, if encountered, as part of the grading proposal. Solid rock shall be considered that which cannot be removed with normal equipment and that required drilling and blasting. This Contractor shall do all rock excavation for the mechanical, plumbing and electrical contractors at the same unit cost. Grading shall be between points where elevations are shown, or between such points and existing grades..3 Grading Outside Building Lines: Grade areas adjacent to building lines to drain away from structures and to prevent ponding. Finish surfaces free from irregular surface changes..4 Grass Areas: Finish area to receive topsoil to within not more than 0.10' above or below the required subgrade elevations.. 5 Walks: Shape surface of areas under walks with finish surface not more than 1/2" above or below the required rough grade elevation.. 6 Grading Surface of Fill Under Building Slabs: Grade smooth and even, free of voids, compacted as specified, and to required elevation. Provide final grades with a tolerance of 1/4" tested with a 10' straightedge.. 7 Backfill shall be suitable material, free of organic material, trash and large rock. Backfill shall be brought up evenly in maximum layer of six inches ( 6") and thoroughly tamped by equipment approved by Architect. Heavy equipment shall not operate closer to the wall than a distance equal to the height of the wall above GRADING ~ 1

2 the footing. Backfill after structural system for building is complete. Backfill excavations as promptly as work permits, but not until completion of the following: a. Acceptance by Architect of construction below finish grade including perimeter insulation. b. Inspection, testing, approval and recording locations of underground utilities. c. Removal of concrete form work. d. Removal of shoring and bracing, backfilling of voids with satisfactory materials. Cut off temporary sheet piling drive below bottom of structures and remove in manner to prevent settlement of the structure or utilities or leave in place if required. e. Removal of trash and debris. f. Permanent or temporary horizontal bracing is in place on horizontally supported walls.. 8 Compact each layer of fill with acceptable equipment to achieve 95% of the maximum density as determined by ASTM D In case of cohesive soil, do not compact material when the moisture varies more than three percent (3%) from the optimum moisture content. A uniform moisture content will be required throughout the layers of fill material. Wetting or drying manipulation shall be required, if necessary, to accomplish this. Suspend compaction operations when, in the Architect's opinion, satisfactory results cannot be obtained because of rain or other unsatisfactory conditions In lieu of drying by manipulation of soil containing excessive moisture, the Contractor may employ hydrated lime, monohydrated lime or similar beneficial ingredients to reduct the moisture content, reduct the plasticity index, improve frost susceptible material or improve workability. Such ingredients shall be applied in a manner and quantity as recommended by the manufacturer or as required by the Architect..11 Embankment and subgrade material which does not contain sufficient moisture to be compacted in accordance with the requirement of the specifications shall be watered as required. Water shall be applied by means of tank trucks equipped with suitable metering devices and shall be thoroughly incorporated into the material by means of discs or other acceptable equipment. GRADING

3 .12 Embankment and suitable material containing excess moisture shall be required to dry prior to or during compaction to a moisture content not greater than three (3) percentage points above optimum, except that for material which displays pronounced elasticity or deformation under the action ofloaded, rubber-tired conveyances, the moisture content shall be reduced to optimum, if necessary, to secure stability. For subgrade material, these requirements for maximum moisture shall apply at the time of compaction of the su\)- grade and also at the time of placing pavement or sub-base. Drying of wet soil may be expedited by the use of plows, discs or by other acceptable methods..13 Soil embanlanent shall be placed and compacted in eight inch (8") layers, loose (jepth, until the density is not less. than the specified percentage of maximum dry density as determined by ASTM D PRODUCTS.1 No Products. 3.0 EXECUTION.1. The Contractor shall employ, at its own expense, a Testing Laboratory to perform all tests and submit reports specified in this Section..2 Tests: The Testing Laboratory shall perform all tests herein specified and submit.test reports to the Architect..3 SUbgrade and Fill Layers: All subgrades and fill layers shall be approved by the Architect before construction of any further work performed. Tests of the subgrades and fill layers shall be taken.as follows: a. On all paved areas, the top 12" of subgrade resulting from excavation shall be compacted to 95% of maximum density at optimum moisture for paved areas. In fill areas, each layer of fill shall meet the required density as specified in compaction section. b. A minimum of one (1) field density test '?fthe sub grade should be made for every 2500 sq. ft. of paved area, but in no case less than three tests. In each compacted fill layer, make one (1) field density test for every 2500 sq. ft. of paved area per lift, but in no case less than three (3) tests..4 The Contractor: The Contractor shall cooperate with the Testing Laboratory in every respect in the performance of the required tests. GRADING

4 .5 The Architect: If, in the opinion of the Architect, based on reports from the Testing Laboratory and inspection, the sub grade or backfills which have been placed are found to be below the specified density, the Architect will require additional compaction and testing tat the expense of the Contraytor;.6 Excavation and grading work shall be carried on in an orderly sequence to provide adequate drainage at all times. Upon completion of each phase of the work, excess material, trash and debris shall be removed from the site. j l I { GRADING I t

5 SECTION TERMITE CONTROL 1.0 GENERAL.1 Provide soil treatment for termite control, as called out on plans.. 2 In addition to the requirements of these specifictions, comply with manufacturer's instruction and recommendations for the work, including preparation of substrate and application.. 3 Engage a professional pest control operator, licensed in accordance with regulations and governing authorities for application of soil treatment solution CONDITIONS.1 Treatment shall not be made when the soil or fill is excessively wet or immediately after heavy rains, to avoid surface flow of the toxicant from application site. Unless the treated areas are to be immediately covered, precautions shall be taken to prevent disturbance of the treatment by human or animal contact with the treated soil. 2.0 MATERIALS.1 Chemicals and concentrations -Apply to soil to be treated, one of the following chemicals: 3.0 EXECUTION a..
