2-1.8 Site Preparation A. Clearing the Site All objectionable growth within the site area planned for building and landscaping improvements shall be cleared. All debris resulting from any clearing, stripping, grubbing, and demolition activities shall be removed from the site at frequent intervals to prevent unsightly accumulation.

B. Demolition All site demolition shall be indicated on a separate demolition plan indicating all items to be turned over to the Garrison and all trees and vegetation that shall remain and be protected during construction.

Perform all demolition of existing surface and underground facilities/improvements as required to construct the project. Demolition plans/details shall be included in the design drawings. Underground facilities shall be removed as required to clear construction and in accordance with good prudent practice and considering potential future construction. At a minimum all structures shall be removed to a point 3' below natural ground. All cavities left below ground shall be filled with compacted native material or a flowable fill material. The portions of piping systems remaining in place shall be neatly cut and capped/plugged. Where partial demolition occurs the remaining portions shall be left in a finished functional condition.

Fill all voids left by clearing and demolition operations with native material compacted in maximum 8" lifts to a density equal to that of the surrounding undisturbed soil.

C. Tree Protection Provide adequate tree protection around all trees in project site that are to remain. Trees designated to remain shall be documented on the plans and tagged in the field. The contractor is to be responsible for protecting the top, trunk, and root system of these trees. Protection shall be by barricading with four (4) inch x four (4) inch posts with two (2) inch x four (4) inch rails (two (2) minimum per side), installed at the drip line of the tree. No equipment, stockpiling of materials, work or parking is to be permitted within the barricades. Root zones shall be protected, where determined by arborist or Garrison representative, as necessary by root pruning at outside edge of barricades.

D. Striping Remove all organics, grasses, roots and topsoil to its full depth to the limits of the areas to be graded. Topsoil free of tree roots, brush and other debris can be stockpiled within the site for subsequent landscaping needs. All material in excess of subsequent needs shall be removed from the site.

E. Grubbing The removal of trees and shrubs shall include the removal of stumps and roots. No stump or root greater than three (3) inches in diameter shall remain in the areas where underground structures, utility lines, footings and pavements are to be constructed. Grubbing in open areas shall remove stumps and roots greater than three (3) inches in diameter to a depth of two (2) feet below finished grade.

2-1.9 Earthwork A. Site Grading Rough Grading: Slopes shall not be steeper than one (1) vertical to five (5) horizontal in general open lawn and other grassed areas. Steeper slopes will be permitted only on a case-by-case basis where special need warrants. Tops and bottoms of banks and other break points shall be rounded to provide smooth and graceful transitions.

In areas of walks without ramps, slopes shall not be steeper than one (1) vertical to twenty

(20) horizontal. Ensure ramped areas comply with the ADA requirements.

Finish Grading: This operation shall consist of the final dressing to provide a uniform layer of either the topsoil or nutrients required for the placement of plant materials or of the subgrade in preparation of pavement construction. This work shall achieve elevations within

0.1 inches of required elevation so that the proper thicknesses of over-layments can be provided.

B. Excavating General For Site: Excavation is to be unclassified and is to be performed as Authorized Excavation regardless of type, nature or condition of the material encountered as necessary to establish the lines and grades to be shown on the drawings. Once subgrade elevations have been reached, A/E is to inspect and determine suitability of subgrade material for intended purpose. If unsuitable, additional excavation can proceed the same as authorized and paid for at the same unit price established in the bid. It is to be stipulated that excavations beyond the limits needed to establish required grades without the specific direction of the A/E will be regarded as unauthorized. Unauthorized excavations and any required remedial work will be at the contractor’s expense.

Excess excavation and material not suitable for backfill and embankment operations shall be removed from the site with the exception that the Garrison reserves the right to select and claim up to the first 2,000 cubic yards. It is to be stipulated that the contractor shall deposit said material, if owner elects, to a location on the installation designated by the Owner at no additional cost. Provisions for maintaining workmen safety within excavations is the sole responsibility of the Contractor.

Trenching: Trench excavations shall be the same as that for general site excavation except that width shall be only to the extent normal for the utility system being installed. A/E is to define normal trench widths and restoration limits paid for with appropriate details in the plans. For excavation beyond normal widths, A/E is to define special backfill requirements at contractor’s expense. Trenching shall establish bottoms to the required lines and grades such that proper bedding of the utility can be accomplished in accordance with the material manufacturer’s recommendations. All trench bottoms are to be maintained dry until properly backfilled and compacted.

A/E is to ensure all applicable safety codes are followed for sheeting, shoring and side slope requirements. Trench excavations shall be guarded at all times. It is to be stipulated that if trenches are to be left open while unattended for any reason, or beyond work hours, they shall be barricaded with orange safety net staked with two (2) inch x four (4) inch posts four

(4) feet from the trench edges.

C. Backfill General for Site and Structures: A non-plastic, clean, granular material composed of sand, fractured rock or gravel obtained from the excavation activities or, if necessary, from offsite borrow shall be provided. The material shall be substantially free of clays, organics including loam, peats and wooden materials and trash, which may be compressible. Quality backfill shall also be void of masonry, rubble and roadway products. Blending of admixtures to improve gradation uniformity and stability is permissible. Provide laboratory verification that intended backfill materials are suitable for the intended purpose. Backfill materials shall be generally placed in 12-inch maximum lifts, loose measure. Specify thinner lifts under structures, pads and pavements as appropriate.

Trenches: Specify select backfill material of equal quality or better stipulated for general site.

Initial placement of material in trenches should be limited to 6-inch lifts to ensure that adequate compaction and support is achieved under the haunches of the pipe to the springline. Placement should then proceed in 6-inch lifts to facilitate proper compaction to 1 foot above the pipe. The remainder of the trench can usually be backfilled and amply compacted in 12-inch lifts. However, the ability to achieve density requirements must be maintained.

D. Excess Material Disposal Excess excavation, backfill, and other construction wastes shall be disposed of offsite to a site secured by the contractor. No on-site burning or burying of wastes will be permitted and no additional cost to the Owner for disposal is to be charged. Excess earth materials not needed for other work shall not be stockpiled temporarily on the site and construction rubble and debris shall be placed in Contractor supplied dumpsters to be picked up on regular intervals.

E. Soil Compaction Quality control testing is to be provided to ensure that fill materials are properly placed and compacted to yield the necessary densities for the support capabilities needed. The A/E is to determine the testing program suitable for the work to be pursued and make recommendation to the Owner. A/E is to assist Owner in selecting a qualified testing laboratory to perform the testing activities and evaluation of the contractor’s work. The Owner will pay for all initial tests conducted. It is to be stipulated that where tests indicate work fails to meet the requirements specified, the contractor, at his expense, shall perform remedial work and retest to verify that the material placement meets the specification requirements.

Compaction Requirements: Specify that soil compaction be evaluated based on the densities determined by Standard Proctor Tests.

General Site: Cuts and embankments not intended to support subsequent work or structures should be compacted to a firmness equal to the adjacent undisturbed soils.

Under Structures: Soil preparations intended to support site related structures shall be compacted to a density of at least 100% of the maximum laboratory density as determined by AASHTO T-99. Compaction under building foundations and structures shall achieve the density requirements established in the geotechnical evaluations and recommendations.

Utility Trenches: Compaction of trench backfill shall achieve the density as stipulated for site structures in paragraph 02240.2.2 above.

Pavements: Areas subject to vehicular traffic shall be prepared in accordance with the provisions of UFC 3-250-18FA, MUTCD, AASHTO Roadside Design Guide, and MDOT standards, latest edition. Densities to be achieved shall be at least 98% of the maximum density as determined by AASHTO T-180.

F. Soil Treatment Ensure applicator is a professional pest control operator licensed in accordance with the regulations governing the application of soil treatment solutions.

Treatment materials applied shall be EPA approved for the application of effective termite control. The product shall be applied in accordance with the manufacturer’s recommendations and the technical data and application instructions are to be submitted to the Garrison prior to commencing.
