No extra payment or time will be allowed for protection of work that could have been suspected or anticipated by site inspection and interpretation of bidding documents prior to execution of contract.

UTILITIES

Any utilities and structures shown on plan drawings are approximate in location and description and are based on records available to the government or on surface features indicating their existence. There may be other utilities within the project area which are not shown. The lack of utilities on plan drawings is not an indication of a utility-free project site.

Notify all affected utility companies of construction operations at least three working days before beginning work near their facilities. Do not begin excavation work until underground utility locations have been marked or the utility company has sent notice that the area is clear.

Use caution when excavating so that the exact location of underground utilities, both known and unknown, may be determined. Provide adequate protection and support for utilities during construction operations.

If uncharted or incorrectly charted utilities are encountered during excavation work, or if proposed construction conflicts with existing utilities, give prompt notice and submit a proposed solution to the COR for approval. If required, make arrangements with utility companies for relocation of interfering utilities. No extra cost or time will be allowed for unexpected delays or coordination work, except for authorized alterations. When a change is permitted to avoid a utility relocation, the COR will determine whether such change constitutes extra work.

Underground utilities and structures located outside of the construction limits which the Contractor wishes to have moved to facilitate construction shall be arranged with each owner of such facilities. The Contractor shall pay all costs of relocations for convenience.

TOPSOIL STRIPPING

Topsoil shall include all friable, fertile, organic clay loam soil suitable for grass and plants, found at surface to a depth of approximately 4 inches, reasonably free of subsoil, clay lumps, stones, objects over 2 inches in diameter, weeds, large roots, root clusters, and other objectionable material.

Strip topsoil from project area to whatever depth encountered. Prevent intermingling with underlaying subsoil or other objectionable material. Remove heavy growths of grass from areas before stripping topsoil.

Where trees are indicated to remain, terminate stripping a sufficient distance from such trees to prevent damage to root systems.

Stockpile topsoil in storage piles in areas where designated. Construct storage piles to freely drain surface water. Cover or sprinkle water on storage piles to prevent windblown dust.

Topsoil stockpiles shall be located to eliminate migration of sediment into wetlands and surface waters. If piles cannot be located to do this, silt fence shall be placed around the stockpiles to keep sediment on the site and out of wetlands and surface waters.

SITE CLEARING

PROTECTION

Protect existing improvements, utilities, trees, and shrubs.

If the project site is known to have invasive plant species, equipment shall be washed before transporting it to a different site on Fort McCoy.

BLASTING

Use of explosives is not permitted.

PRODUCTS

CLASSIFICATION

Excavation of materials encountered under this work will be unclassified without regard to type, difficulty of removal, or suitability for use in construction.

EXECUTION

PREPARATION

Lay out work to be performed in accordance with project specifications and/or drawings.

EXCAVATION FOR STRUCTURES

Excavate to achieve the necessary dimensions, lines, and grades. Conform to elevations and dimensions shown within a tolerance of 0.10 feet, and extending a sufficient distance from footings and foundations as required for bracing and supports, concrete formwork, installation of services, and other required construction, and for inspection.

For footings and foundations, do not disturb the bottom of the excavation. Excavate to final grade just before concrete is placed. Trim bottoms to required lines and grades to leave solid, undisturbed base to receive granular fill, base course, or concrete.

UNAUTHORIZED EXCAVATION

Unauthorized excavation consists of removal of materials beyond indicated or required elevations or side dimensions without specific direction of COR. Unauthorized excavation, as well as remedial work, shall be at the Contractor’s expense. Notify COR if unauthorized excavations are made.

Under footings and foundations, fill unauthorized excavation by extending indicated bottom elevation of footing or foundation without altering required top elevation. Lean concrete or compacted fill may be used to bring elevations to proper position only when approved by the COR.

In all other locations, unauthorized excavations shall be backfilled and compacted as specified for authorized excavations of the same classification, unless otherwise directed.

ADDITIONAL EXCAVATION (OVER EXCAVATION)

When excavation has reached required subgrade elevation, notify COR who will make an inspection of conditions. Inform COR of unsuitable, unconsolidated subgrade soils.

If unsuitable bearing materials such as poorly compacted fill, existing foundations, rubble, debris, or organic deposits are encountered at required subgrade elevations, carry excavations deeper and replace excavated material with properly compacted Structural Fill as directed by COR.

Removal of unsuitable material and its replacement as directed will be paid for as extra work. Do not proceed with extra work unless authorized.

EXCAVATION FOR UTILITY TRENCHES

Trenches for underground utility systems shall be excavated to the required alignments and depths.

STABILITY OF EXCAVATIONS

Maintain sides and slopes of excavations in a safe condition until completion of backfilling. Shore and brace as required where sloping is not possible either because of space restrictions or stability of the materials excavated.

Take precautions to prevent slides or cave-ins when excavations are made in locations adjacent to backfilled excavations, and when sides of excavations are subjected to vibrations from traffic, machinery, or any other source.

Comply with the requirements of the Occupational Safety and Health Administration and with all other applicable codes and ordinances.

SHORING AND BRACING

All shoring and bracing must comply with the requirements of the Occupational Safety and Health Administration and with all other applicable codes and ordinances.

Carry down shoring and bracing as required as excavation progresses. Maintain shoring and bracing while excavations are open.

Provide and maintain shoring and bracing, such as sheet piling, uprights, stringers, and cross braces in good serviceable condition. Use timbers that are sound and free of large or loose knots.

Provide permanent steel sheet piling or pressure treated timber sheet piling wherever subsequent removal of sheet piling might permit lateral movement of soil under adjacent structures. Cut off tops as required and leave permanently in place.

DEWATERING

Perform earthwork in a manner to prevent surface water and ground water from flowing into excavations. Promptly remove water from excavations using pumps, sumps, and dewatering system components necessary to convey water away from excavations. If underground springs are encountered, notify COR before proceeding.

Convey water removed from excavations and rain water to collection or run-off areas. Provide and maintain temporary drainage ditches or other diversions outside excavation limits for each structure. Do not use foundation or utility trench excavations as temporary drainage ditches.

STOCKPILING

Stockpile excavated materials meeting requirements for fill and backfill where directed until required for the work. Place, grade, and shape stockpiles for proper drainage. Locate stockpiles a sufficient distance from edge of excavations, even though such excavations may be sheeted and braced, to prevent material from falling or sliding into excavations and to prevent cave-ins.

Locate stockpiles to eliminate migration of sediment into wetlands and surface waters. If stockpiles cannot be located to do this, silt fence shall be placed around the stockpiles to keep sediment on the site.

FINISH GRADING

Complete grading, trimming, and finishing of excavation bottom before constructing the subbase, base, or surface courses.

Make gradual adjustments in slopes to blend with existing landscape features, especially at the intersection of cuts and fills.

COLD WEATHER PROTECTION

Protect excavation bottoms against freezing when atmospheric temperature is less than 35 degrees Fahrenheit by covering with dry insulating materials of sufficient depth to prevent frost penetration.

DISPOSAL OF EXCESS AND WASTE MATERIALS

Remove excess excavated material, trash, debris, and other waste materials and legally dispose of them off of Fort McCoy.

Any excavated material that is infested with invasive seed and is not used on this site should not leave this site for use on another Fort McCoy project. This material shall be disposed of separately. Contact the Fort McCoy Wildlife Program (608-388-2308 or 608-388-5374) for disposal locations for this material. Sites with invasive species shall be identified by Fort McCoy Wildlife prior to construction and the Contractor will be notified.

SECTION 02317

BACKFILL/FILL MATERIAL

GENERAL

SCOPE

Install fill material as required for this project.

SUBMITTALS

PROTECTION

Protect existing improvements, utilities, trees and shrubs.

If the project site is known to have invasive plant species, equipment shall be washed before transporting it to a different site on Fort McCoy.

PRODUCTS

FILL MATERIALS, GENERAL

Fill materials shall be free of organic matter, debris, frozen soils, ice, and other objectionable materials.

Select existing material from required excavations may be used for fill or backfill if it meets the specified product requirements.

Material imported from a different location on Fort McCoy should be free of invasive plant species. These invasive species include but are not limited to:

Wild Parsnip Leafy Spurge Spotted Knapweed Garlic Mustard Buckthorn Reed Canary Grass Purple Loosestrife Contact Fort McCoy Wildlife Program (608-388-2308 or 608-388-5374) to inspect a borrow site prior to using the site for fill material.

Do not bring fill material into the project from outside sources without prior approval from the COR and from Fort McCoy Wildlife Program (608-388-2308 or 608-388-5374).

GRANULAR FILL

Select natural sand or a mixture of sand with gravel, crushed gravel, crushed stone, or other broken or fragmented material.

Aggregate shall pass a 1-1/2 inch sieve and not more than 35% shall be retained on a No. 10 sieve. A maximum 5% by weight shall pass a No. 200 sieve.

STRUCTURAL FILL

Select natural sand or a mixture of sand with gravel, crushed gravel, crushed stone, or other broken or fragmented material.

Aggregate shall pass a 1-1/2 inch sieve and not more than 35% shall be retained on a No. 10 sieve. Maximum 12% by weight shall pass a No. 200 sieve.

GRANULAR BEDDING AND BACKFILL

Select soils suitable for use as Granular Fill, except course aggregate shall pass a ¾ inch sieve.

BACKFILL

Previously excavated soils, free of aggregate larger than 3 inches, and suitable for intended purpose.

EXECUTION

PREPARATION

Remove all vegetation, rubbish, and other unsatisfactory materials within the area upon which fill is to be placed.

Lay out work to be performed in accordance with the project specifications and/or drawings.

EXAMINATION OF SUBGRADE

Examine subgrade prior to placement of fill or backfill. Do not place materials on frozen subgrade. Plow, strip, or break-up sloped surfaces steeper than 1 vertical to 4 horizontal so that material will bond with subgrade.

When subgrade has a density less than that specified for the particular area, break-up ground surface, pulverize, moisture-condition to optimum content, and compact top 12 inches to the density specified in PART 4 SCHEDULES.

FILLING AND BACKFILLING, GENERAL

Construct fills starting at the lowest point of the fill. Construct the fill in layers by spreading and leveling the material during placement. Spread individual layers evenly to uniform thickness throughout and approximately parallel with the finished grade for the full width of the fill, unless directed otherwise. Place materials in lift thicknesses as determined by PART 4 SCHEDULES. Compact and density test a complete lift prior to placing material for successive lifts.

Do not place fill or backfill until required excavation and subgrade preparation have been inspected and approved by the Inspector.

Adjacent to structures, place fill or backfill to prevent damage and to allow structures to assume loads gradually and uniformly, at approximately the same rate on all sides of the structure. Adjacent to earth-retaining structures, do not place fill or backfill until concrete has reached its specified 28-day compressive strength. Do not travel heavy equipment over cast-in-place concrete work until it has reached specified 28-day compressive, unless otherwise approved. If after 14 days of curing the specified 28-day compressive strength has been achieved, work may proceed.

Backfill all spaces excavated and not occupied by new structures to the specified section.

If there is water in the excavation, dewater the excavation, or, upon approval of the COR, perform backfilling so that the backfill material displaces the water and does not trap it within the fill.

Backfill excavations as promptly as work permits, but not until completion of the following:

Acceptance by the COR of construction below finish grade.

Removal of concrete formwork.

Removal of shoring and bracing and backfilling of voids with satisfactory materials. Cut off temporary sheet piling driven below bottom of structures and remove in manner to prevent settlement of the structure or utilities, or leave in place if required.

Removal of trash and debris.

Warning tape for Utility Trenches Install warning tape not more than 12 inches above the direct burial cable or pipe.

Tape shall be 4 inches wide.

The tape shall be manufactured with integral wires, foil backing, or other means to enable detection by a metal detector when the tape is buried up to three feet deep.

The tape shall be of a type specifically manufactured for marking and locating underground utilities.

The tape shall be of the correct color for the utility and shall bear a continuous printed inscription describing the specific utility.

Tracer wire Install tracer wire at all non conductive pipe.

Tape to pipe at 5’ intervals.

Wire shall be #14 magnetic detectable conductor with polyethylene insulation rated for direct burial.

CONTROL OF MOISTURE CONTENT

During placement and compaction, maintain moisture content of materials within optimum range.

Apply water to fill materials after placement as necessary. Obtain uniform moisture distribution by disking, plowing, or other approved mixing methods prior to the compaction of a layer.

If material is too wet when deposited on fill, remove or dry it to the required moisture content prior to compaction.

If top surface of a preceding layer of compacted fill becomes too dry to permit suitable bond, scarify and moisten it to the required moisture content prior to placement of the next layer of fill.

COMPACTION

Compact all fills using standard compaction methods unless the contract specifies special compaction.

Provide the required compaction for each layer before placing any material for a succeeding layer.

Compact each layer of soil material to not less than the percentage of maximum density specified in PART 4 SCHEDULES.

Provide compaction equipment required to obtain specified compaction. Compaction by travel of grading equipment is not considered adequate for uniform compaction. Small vibratory compactors are required wherever fill is placed adjacent to foundation walls, footings, and piers.

MAINTENANCE

Where completed compacted areas are disturbed by subsequent construction operations or adverse weather, scarify surface, re-shape, and compact to required density prior to further construction.

Where settling is measurable or observable at excavated areas during general project warranty period, remove surface (pavement, lawn, or other finish), add fill or backfill material, compact, and replace surface treatment. Restore appearance, quality, and condition of surface or finish to match adjacent work and eliminate evidence of restoration to greatest extent possible.

PART 4 SCHEDULES

4.01 COMPACTION SCHEDULE

(1) Place manually compacted materials in maximum 4 in. layers.

(2) Percent of maximum density determined in accordance with ASTM D1557 (Modified Proctor Test).

Systematically backfill to allow maximum time for natural settlement. Do not backfill over porous, wet, frozen or spongy subgrade surfaces.

Employ a placement method that does not damage the wiring in the trench.

Maintain optimum moisture content of backfill materials to attain required compaction density.

Remove surplus backfill materials from site to a designated disposal area.

Leave fill materials stockpile areas completely free of excess fill materials.

TOLERANCES

Top Surface of Backfilling: Plus or minus one inch from required elevations.

Contractor shall repair areas that settle more than 2” during the warranty period.

FIELD QUALITY CONTROL

Field inspection and testing will be performed by the Contractor.

Tests and analysis of fill material will not be necessary.

PROTECTION OF FINISHED WORK

Protect finished work until the start of the next stage of construction or until accepted by the COR.

Compact fills subjected to vehicular traffic.
