SOIL MATERIALS Clause Samples

SOIL MATERIALS. A. Fill material is subject to the approval of the Engineer and may be either material removed from excavations or borrow from off site. Fill material, whether from the excavations or from borrow, shall be of such nature that after it has been placed and properly compacted, it will make a dense, stable fill. B. In no case shall Remediation Waste, as that term is defined under 310 CMR 40.0000, be used or re-used as fill material. C. Satisfactory fill materials shall include materials classified by ASTM D 2487 as GW, GP, GM, GP-GM, ▇▇-▇▇, GC, GP-GC, SW, and SP. D. Satisfactory fill materials shall not contain trash, refuse, vegetation, masses of roots, individual roots more than 18 inches long or more than 1/2 inch in diameter, or stones over 6 inches in diameter. Organic matter shall not exceed minor quantities and shall be well distributed. E. Satisfactory fill materials shall not contain frozen materials nor shall backfill be placed on frozen material. F. Excavated surface and/or pavement materials such as gravel or trap rock that are salvaged may be used as a sub-grade material. In no case shall salvaged materials be substituted for the required gravel base.

SOIL MATERIALS. General: Provide borrow soil materials when sufficient satisfactory soil materials are not available from excavations.

SOIL MATERIALS. A. Topsoil Backfill: All soil backfill shall be high quality topsoil and will be free of rocks larger than 1.0 inches, sticks, roots and other debris.

SOIL MATERIALS. 10.1 Clean Fill - Clean fill (stripping or excavated materials) will be deposited in an area designated for this purpose, and in accordance with Banff National Park Directive # 22, "Guidelines for Management of Excavated Materials". 10.2 Stripping - The topsoil layer in the BNP area is frequently very thin. Successful site rehabilitation depends on either careful saving of the limited topsoil resource, or undertaking the expensive alternative of hauling topsoil from outside the Park. - Measures required to conserve the valuable topsoil resource must be identified. This may include stockpiling on-site for immediate rehabilitation, or disposal at an area designated by the Superintendent. - Care must be taken during both grubbing and stripping operations to ensure that the trees and roots on the edge of the clearing limits are not disturbed or damaged. This phase will be closely monitored by HRC. - In some instances where steep backslopes are involved, grubbing and stripping may not be permitted. Stumps would be cut flush with the ground, and the ground cover left undisturbed to promote slope stability. This will be determined by an on-site inspection by HRC. - Material encountered below the topsoil layer, which is not suitable for construction purposes may be disposed of at designated locations in accordance with Park Directive #22,"Guidelines for Management of Excavated Materials". Arrangements to dispose of the surplus material must be made with the Park Warden responsible for monitoring the project. - Depending on the type and volume of material encountered, special conditions may be imposed regarding compaction and rehabilitation at the disposal area. 10.3 Contaminated Soil - The issue of contaminated soils and disposal practices will normally be identified through ▇▇▇▇. However, where past and present land use practices have led to soil contamination, certain actions will be required. These include: - Soil testing at the expense of the proponent. Level of contamination will be in accordance with the Canadian Council of Ministers of the Environment guidelines, and acceptable levels will be decided by the park. Minimum acceptable standards for in-park soil contamination and remediation will be to the "Parkland" level. - Soil disposal at the expense of the proponent. All contaminated soils will be removed from the park. No treatment of contaminated soils (ie. bio- remediation, land-farming, etc.) will be allowed within the park. Disposal of contaminated so...

SOIL MATERIALS. A. General: Provide borrow soil materials when sufficient satisfactory soil materials are not available from excavations. B. Satisfactory Soils: Soil Classification Groups GW, GP, GM, SW, and SP according to ASTM D 2487, or a combination of these groups; free of rock or gravel larger than 3-inches in any dimension, debris, waste, frozen materials, vegetation, and other deleterious matter. C. Unsatisfactory Soils: Soil Classification Groups SM, GC, SC, CL, ML, OL, CH, MH, OH, and PT according to ASTM D 2487, or a combination of these groups. 1. Unsatisfactory soils also include satisfactory soils not maintained within 2 percent of optimum moisture content at time of compactions. 2. Unsatisfactory materials also include materials below structures and/or foundations determined by the Owner’s Representatives to be unsatisfactory bearing materials. D. Subbase Course: Naturally or artificially graded mixture of natural or crushed gravel, crushed stone, and natural or crushed sand; NYSDOT Type 1. The use of recycled material from any off-site source will not be permitted and recycled material from onsite demolition may not be used without written authorization from the owner. E. Structural Fill: Naturally or artificially, well graded mixture of natural or crushed gravel, crushed stone, and natural or crushed sand; ASTM D 2940; with at least 9- percent passing a 1 ½ - inch sieve and not more than 12 percent passing a No. 200 sieve. This material must be approved by the Owner’s Representatives. F. Bedding Course: Naturally or artificially graded mixture of natural or crushed gravel or crushed stone; ASTM D 2940; except with 100 percent passing a 1-inch sieve and 0 to 5 percent passing a No. 8 sieve. G. Trap Rock: Narrowly graded mixture of washed crushed stone ASTM D 448; coarse- aggregate grading Size 1; with 100 percent passing a 4-inch sieve and 0 to 15 percent passing a 1 ½ - inch sieve. H. Sand: ASTM C 33; fine aggregate. I. Topsoil and other Planting Media: See Division 32 Section 329000 Planting Media Preparation and Placement. J. CLSM high slump mixture of Portland cement, fly ash and fine aggregate formulated, licensed and marked K-Krete or equal. 1. Provide mixture with a 28-day compressive strength of 200 psi with no measurable shrinkage or surface settlement.

SOIL MATERIALS. A. General: Provide borrow soil materials when sufficient satisfactory soil materials are not available from excavations. B. Satisfactory Soils: ASTM D 2487 Soil Classification Groups SC, GC, CL, or a combination of these groups; free of rock or gravel larger than 3 inches (75 mm) in any dimension, debris, waste, frozen materials, vegetation, and other deleterious matter.
