PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Lower District Shop currently has an ageing and deteriorated perimeter fence system that no longer provides adequate security or functionality. Portions of the existing fence and gates are damaged, misaligned, or at the end of their service life, resulting in unsecured areas that allow uncontrolled access to maintenance yards and stored materials. In addition, the lack of defined, secure storage areas has led to unorganized material storage, increasing the risk of material loss, safety hazards, and operational inefficiencies. The proposed improvements will replace outdated infrastructure, restore site security, and establish organized storage to support safe and efficient maintenance operations.

Rays Garage currently lacks secure, designated storage areas for equipment and materials, leaving assets exposed and contributing to inefficient site operations. The absence of fencing and defined storage areas limits the ability to control access, organize materials, and support routine maintenance activities. These conditions reduce operational efficiency and increase the potential for material loss and safety concerns. The proposed work will establish secure perimeter fencing, controlled access, and a dedicated material storage area, resulting in improved operational efficiency, asset protection, and overall functionality of the Rays Garage site.

Construction Specification 31 23 00 – Earthfill and Gravel Fill

1. Scope The work consists of the construction of earth embankments, other earthfills, earth backfills, and gravel fills required by the drawings and specifications.

2. Material

All fill material shall be obtained from required excavations and approved borrow areas.

The selection, blending, routing, and disposition of material in the various fills shall be subject to approval by the engineer.

Fill materials shall contain no frozen soil, sod, brush, roots, or other perishable material.

Rock particles larger than the maximum size specified for each type of fill shall be removed prior to compaction of the fill.

Earth fill is composed of natural earth materials that can be placed and compacted by construction equipment operated in a conventional manner

Gravel Fill:

Gravel fill material shall be sand, gravel, or crushed stone, or mixtures thereof, obtained from the specified sources. The material shall be selected as necessary to avoid the inclusion of organic matter, clay balls, excessive fine particles, or other substances that would interfere with their free-draining properties. If requested, samples shall be provided to NRCS prior to construction for approval.

3. Foundation preparation

Foundations for earthfill and gravel fill shall be stripped to remove vegetation and other unsuitable material or shall be excavated as specified. All stumps and roots having a diameter of one inch or larger shall be grubbed out to a depth of at least two feet below subgrade elevation for concrete structures and one foot below the ground surface at embankment sites and other designated areas.

Except as otherwise specified, each foundation surface shall be graded to remove surface irregularities and shall be scarified parallel to the axis of the fill or otherwise acceptably scored and loosened to a minimum depth of 2 inches. The moisture content of the loosened material shall be sufficient to insure a good bond between layers or shall be controlled as specified. The surface material of the foundation shall be compacted and bonded with the first layer of earthfill as specified for subsequent layers of earthfill.

Foundations for gravel fill shall not be scarified. Unless otherwise specified, foundations shall be compacted by routing earthmoving equipment over the entire surface. Soft or weak areas shall be excavated and backfilled with suitable material to provide a firm, uniform foundation.

Earth abutment surfaces shall be free of loose, uncompacted earth in excess of 2 inches in depth normal to the slope and shall be at such a moisture content that the earthfill can be compacted against them to produce a good bond between the fill and the abutments.

NRCS ME 423-2 May 2017

Rock foundation and abutment surfaces shall be cleared of all loose material by hand or other effective means and shall be free of standing water when fill is placed upon them.

Occasional rock outcrops in earth foundations for earthfill, except in dams and other structures designed to restrain the movement of water, shall not require special treatment if they do not interfere with compaction of the foundation and initial layers of the fill or the bond between the foundation and the fill.

Foundation and abutment surfaces shall be no steeper than one horizontal to one vertical unless otherwise specified. Test pits or other cavities shall be filled with compacted earthfill conforming to the specifications for the earthfill to be placed upon the foundation.

4. Placement

Earth fill or drain fill shall not be placed until the required excavation and foundation preparation have been completed and the foundation has been inspected and approved by the engineer or other qualified official. Earth fill or drain fill shall not be placed upon a frozen surface nor shall snow, ice, or frozen material be incorporated in the earthfill matrix.

Fill shall be placed in approximately horizontal layers. The thickness of each layer before compaction shall not exceed the maximum thickness specified. Materials placed by dumping in piles or windows shall be spread uniformly to not more than the specified thickness before being compacted.

Hand compacted fill shall be placed in layers whose thickness before compaction does not exceed the maximum thickness specified for layers of earth backfill compacted by manually directed power tampers.

Earth backfill shall be placed in a manner that prevents damage to the structures and allows the structures to assume the loads from the earth backfill gradually and uniformly.

The height of the earth backfill adjacent to a structure shall be increased at approximately the same rate on all sides of the structure.

Earthfill and earth backfill in dams, levees, and other structures designed to restrain the movement of water shall be placed to meet the following additional requirements:

(a) The distribution of materials throughout each zone shall be essentially uniform, and the earthfill shall be free from lenses, pockets, streaks, or layers of material differing substantially in texture, moisture content, or gradation from the surrounding material. Zone earthfills shall be constructed concurrently unless otherwise specified.

(b) If the surface of any layer becomes too hard and smooth for proper bond with the succeeding layer, it shall be scarified parallel to the axis of the fill to a depth of not less than 2 inches before the next layer is placed.

(c) The top surface of embankments shall be maintained approximately level during construction with two exceptions: A crown or cross-slope of about 2 percent shall be maintained to ensure effective drainage, or as otherwise specified for drainfill or sectional zones.

(d) Dam embankments shall be constructed in continuous layers from abutment to abutment except where openings to facilitate construction or to allow the

NRCS ME 423-3 May 2017 passage of streamflow during construction are specifically described in the design.

(e) Embankments built at different levels as described under (c) or (d) above shall be constructed so that the slope of the bonding surfaces between embankment in place and embankment to be placed is not steeper than 3 feet horizontal to 1 foot vertical. The bonding surface of the embankment in place shall be stripped of all material not meeting the requirements of this specification and shall be scarified, moistened, and recompacted when the new earthfill is placed against

it. This ensures a good bond with the new earthfill and obtains the specified moisture content and density at the contact of the inplace and new earthfills.

Any damage to the foundation surface or the trench sides or bottom occurring during placement of drain fill shall be repaired before drain fill placement is continued.

Drain fill over and/or around pipe or drain tile shall be placed to avoid any displacement in line or grade of the pipe or tile.

5. Control of moisture content

During placement and compaction of earth fill and earth backfill, the moisture content of the material being placed shall be maintained within the specified range. Unless otherwise specified, the fill material shall be moist enough so that material can be formed into a ball between the hands without crumbling. If the ball crumbles, the material is too dry. If the ball extrudes out of the hand when squeezed tightly, the material is too wet.

The application of water to the earthfill material shall be accomplished at the borrow areas insofar as…
