ARTICLE II: EXCAVATION, GRADING AND SITE WORK

Sec. 2.01. Standards.

The following excavation, grading and site work standards shall apply to all construction within the Village:

1. GENERAL

This section covers excavation, grading, and site work and shall include the necessary clearing, grubbing, and preparation of the site; removal and disposal of all debris; excavation and trenching as required; the handling, storage, transportation, and disposal of all excavated material; all necessary sheeting, shoring, and protection work; preparation of subgrades; pumping and dewatering as necessary or required; protection of adjacent property; backfilling; construction of fills and embankments; surfacing and grading; and other appurtenant work.

2. GENERAL REQUIREMENTS

A. All work shall be performed in a safe and proper manner with suitable precautions being taken against all hazards. Excavations shall provide adequate working space and clearances for the work to be performed therein and for installation and removal of concrete forms. In no case shall excavation faces be undercut for extended footings.

B. Subgrade surfaces shall be clean and free of loose material of any kind when concrete is placed thereon.

C. Except where exterior surfaces are specified to be damp proofed, monolithic concrete manholes and other concrete structures, or parts thereof, which do not have footings that extend beyond the outside face of exterior walls, may be placed directly against excavation faces without the use of outer forms, provided that such faces are stable and also provided that a layer of polyethylene film is placed between the earth and the concrete.

D. Excavations for manholes and similar structures constructed of masonry units shall have such horizontal dimensions that not less than six (6) inches clearance is provided for outside plastering.

E. Backfilling and construction of fills and embankments during freezing weather shall not be done except by permission of the Engineer. No backfill, fill, or embankment materials shall be installed on frozen surfaces, nor shall frozen materials, snow, or ice be placed in any backfill, fill, or embankment.

3. CODES AND STANDARDS

The Contractor shall comply with all codes, laws, ordinances, and regulations of governmental authorities having jurisdiction over this part of the Work.

4. SITE PREPARATION

All sites to be occupied by permanent construction or embankments shall be cleared of all logs, trees, roots, brush, tree trimmings, and other objectionable materials and debris. All stumps shall be grubbed. In addition, subgrades for fills and embankments shall be cleaned and stripped of all surface vegetation, sod, and organic topsoil. All waste materials shall be removed from the site and disposed of by and at the expense of the Contractor. Open burning will not be permitted.

5. EXAMINATION OF SITE AND RECORDS

A. The Contractor shall examine the site, the Drawings, and any records of existing subsurface soil explorations, including any addenda thereto. Subsurface soil exploration reports and records of test borings are made available for information only and are not guaranteed to represent all subsurface conditions that will be encountered. Other construction of which no records are available may be encountered. The Contractor shall formulate his own conclusions as to the extent of such construction and remove all material of any nature to the design subgrades indicated or hereinafter specified.

B. The Contractor shall remove all existing on-grade or below grade construction which may be encountered in areas to be occupied by the new structures. In areas of general grading and areas that are to be paved, he shall remove all obstructions that 20(2) may be encountered to a depth of at least twenty-four (24) inches below the design grades.

C. Existing road pavement to be replaced by new roads under this Contract shall be removed from the site and disposed of by the Contractor or used in earth fills and embankments as specified.

6. TOPSOIL

The Contractor shall strip all topsoil encountered over the entire developed portion of the site. Topsoil shall be stockpiled for use indicated, or directed, free of any admixture of subsoil, stones, clods of earth, plants, roots, sticks, or other matter not conducive to plant growth. After all work has been completed in each area, topsoil shall be placed and graded to the satisfaction of the Village.

7. PRESERVATION OF TREES

No trees shall be removed outside of excavated or filled areas, unless the Village authorizes their removal. Trees left standing shall be adequately protected from permanent damage by construction operations. Trimming of standing trees, where required, shall be as directed by the Village.

8. BLASTING

A. The Contractor shall comply with all laws, ordinances, applicable safety code requirements, and regulations relative to the handling, storage, and use of explosives and the protection of life and property. The Contractor shall be responsible for all damage caused by his blasting operations. Suitable methods shall be employed to confine all materials lifted by blasting within the limits of the excavation or trench.

B. All rock which cannot be handled and compacted as earth shall be kept separate from other excavated materials and shall not be mixed with backfill or embankment materials except as specified or directed.

C. The Contractor shall submit a proposed method of blasting, including location, size, and depth of drill holes; size, type and location of charges; detonation sequence; and time of blasting; to the Village for review at least one (1) month prior to the proposed time of blasting.

9. DEWATERING

A. The Contractor shall provide and maintain adequate dewatering equipment to remove and dispose of all surface and ground water entering excavations, trenches, or other parts of the Work. Each excavation shall be kept dry during subgrade preparation and continually thereafter until the structure to be built, or the pipe to be installed therein is completed, to the extent that no damage from hydrostatic pressure, flotation, or other cause will result.

B. All excavations for concrete structures or trenches which extend down to or below static ground water shall be dewatered by lowering and keeping the ground water level beneath such excavations twelve (12) inches or more below the bottom of the excavation.

C. Surface water shall be diverted or otherwise prevented from entering excavated areas or trenches to the greatest extent practicable without causing damage to adjacent property.

D. The Contractor will be held responsible for the condition of any pipe or conduit which he may use for drainage purposes, and all such pipes or conduits shall be left clean and free of sediment.

10. SHEETING AND SHORING

A. Except where banks are cut back on a stable slope, excavation for structures and trenches shall be properly and substantially sheeted, braced, and shored, as necessary, to prevent caving or sliding, to provide protection for workmen and the Work, and to provide protection for existing structures and facilities. Sheeting, bracing, and shoring shall be designed and built to withstand all loads that might be caused by earth movement or pressure, and shall be rigid, maintaining shape and position under all circumstances.

B. Trench sheeting shall not be pulled before backfilling unless the pipe strength is sufficient, in the opinion of the Village, to carry trench loads based on trench width to the back of sheeting, nor shall sheeting be pulled after backfilling. Where trench sheeting is left in place, such sheeting shall not be braced against the pipe, but shall be supported in a manner that will preclude 20(3) concentrated loads or horizontal thrusts on the pipe. Cross braces installed above the pipe to support sheeting may be removed after pipe embedment has been completed.

11. SUBGRADE STABILIZATION

A. Subgrades for concrete structures, roads and walks, and trench bottoms shall be firm, dense, and thoroughly compacted and consolidated; and shall be sufficiently stable to support construction equipment, to support concrete substructures during placement, and to remain firm and intact under the feet of the workmen.

B. Subgrades for concrete structures or trench bottoms which are otherwise solid, but which become mucky on top to construction operations, shall be reinforced with crushed rock or gravel.

C. The finished elevation of stabilized subgrades shall not be above subgrade elevations shown on the Drawings.

12. STRUCTURAL EXCAVATION

A. The method of excavation is at the Contractor's option. The Contractor shall excavate for all work to the lines and elevations as required on the Drawings, but shall not excavate below elevations shown on the Drawings without the approval of the Village.

B. All footing subgrades shall be approved by the Testing Laboratory before proceeding with the construction of piers, walls, and footings. Bottoms of all footings shall be founded on competent, undisturbed soil at elevations as indicated on the Drawings.

C. Subgrades of all footings shall be level and clean of all loose rock, dirt, and debris and free of standing water prior to acceptance of pouring concrete.

D. When suitable bearing soil is not encountered at the subgrade elevations indicated on the Drawings and the excavation is made to a greater depth, the footings and foundation walls shall be extended to the lower elevation or lean concrete fill shall be provided by the Subcontractor for this part of the Work without additional cost to the Owner.

E. In the event latent soil conditions are encountered at the subgrade elevations indicated on the Drawings as determined by the Village, the Village may direct the removal of the unsuitable soil and extension of the footings and foundation walls or the installation of lean concrete fill as the case may be. Payment for such authorized additional work shall be made in accordance with the terms set forth in the Contract Documents.

F. The Contractor shall perform all site grading indicated on the Drawings. Grading shall be controlled in the vicinity of excavated areas so that the surface of the ground will be properly sloped to prevent water from running into the excavated areas. Such areas shall be kept reasonably dry at all times. Accumulated water shall be removed by pumping.

13. ROADWAY EXCAVATION

Roadway excavation shall consist of excavation for the roadways, drives, and parking areas in conformity with lines, grades, cross sections, and dimensions shown on the Drawings and shall include the excavation of all unsuitable material from the subgrade. After shaping to line, grade, and cross section, the subgrade shall be rolled until compacted to a depth of at least eight (8) inches to ninety-five percent (95%) of maximum density at optimum moisture content as determined by ASTM D698. This operation shall include any reshaping and wetting required to obtain proper compaction. All soft or otherwise unsuitable material shall be removed and replaced with suitable material.

14. TRENCH EXCAVATION

A. Trenches shall be excavated so that pipes can be laid straight at uniform grade, without dips or humps, between the terminal elevations shown on the Drawings.

B. Where pipe grades or elevations are not definitely fixed by the Contract Drawings, trenches shall be excavated to a depth sufficient to provide a minimum depth of backfill cover over the top of 66 inches for water piping and 24 inches for gas piping.

C. Trenches shall be excavated to a width that will provide adequate working space and pipe clearances for proper pipe installation, jointing, and bedding. However, limiting trench widths below an elevation 6 inches above the top of installed pipe, 20(4) and minimum permissible clearances between the installed pipe and each trench wall, expressed in inches, shall be as follows:

PIPE MINIMUM MAXIMUM SIZE (in) TRENCH WIDTH (in) TRENCH WIDTH (in) 6 18 24 8 20 24 10 22 24 12 26 30 14 28 36 15 30 36 16 33 36 18 35 40 21 39 44 24 44 48 27 49 48 30 54 60

Stipulated minimum clearances are not minimum average clearances, but are minimum clear distances that will be required.

D. Where necessary to reduce earth load on trench banks to prevent sliding and caving, banks may be cut back on slopes that shall not extend lower than one foot above the top of the pipe.

E. Except where otherwise required, pipe trenches shall be excavated below the underside of the pipe to provide for the installation of granular bedding pipe foundation material.

F. Excavation for joints shall be only that required for properly making the particular type of joint. The Contractor shall not excavate below the depths indicated, and backfill for any over - depth not specifically authorized as hereinafter specified shall be at the expense of the Contractor.

G. Whenever rock is encountered, the Contractor shall excavate the trench bottom to a minimum over depth of four (4) inches below the required depth, backfill with gravel, and compact as specified hereinafter. Whenever wet or otherwise unstable soil that is incapable of supporting the pipe or conduit, as determined by the Village, is encountered in the bottom of the trench, he shall remove such soil to the depth authorized, backfill the trench, and compact as specified below, to the proper grade with gravel. Such excavation of unstable soil as authorized by the Owner shall be a subsidiary obligation to the installation of conduit systems.

H. Whenever pipe is located along or across an improved surface, the width of the trench shall be held as nearly as possible to the minimum width necessary to complete the work.

I. In some instances, trees, fire hydrants, sidewalks, and other obstructions may be encountered, the proximity of which may be a hindrance to open - cut excavation. In such cases, the Contractor shall excavate by means of short tunnels in order to protect such obstructions against damage. Such short tunnel work shall be considered incidental to the construction of the pipeline and shall not be grounds for extra payment or payment for tunnel work.

15. DETENTION BASIN EXCAVATION

A. Excavation shall be in conformity with lines, grades, cross sections, and dimensions shown on the Drawings. Topsoil shall be removed prior to grading and stored for usage later.

B. For dry-type detention basins, excavation shall be made four (4) to six (6) inches below the grades indicated on the drawings to allow for the placement of topsoil. This procedure shall also be followed for wet detention basins for those areas above the normal water level elevation.

C. If after excavation to the final grade it is found that unsuitable material exists, the side slopes of dry detention basins and the side slopes of all wetted areas of wet detention basins shall be lined with a minimum of six (6) inches and a maximum of nine inches (9) of clay soil. Additional excavation shall be made to allow proper placement of the clay soil to the line and grades indicated on the drawings. After shaping to line and grade, the clay soil shall be compacted to ninety-five percent (95%) of maximum density at optimum moisture content as determined by ASTM D698.

20(5)

16. EXCAVATION FOR APPURTENANCES

Excavation for manholes, catch basins, inlets, and similar structures shall be sufficient to leave at least twelve (12) inches in the clear between their outer surfaces and the embankment or timber which may be used to hold and protect the banks. Any over depth excavation below appurtenances that has not been directed shall be considered as unauthorized and shall be backfilled with concrete at the expense of the Contractor.

17. UNAUTHORIZED EXCAVATION

Except where otherwise authorized, shown, or specified, all material excavated below the bottom of concrete walls, footings, slabs, on grade and foundations shall be replaced, by and at the expense of the Contractor, with concrete placed at the same time and monolithic with the concrete above.

18. FILLS AND EMBANKMENTS

A. Suitable fill material shall be provided as necessary to construct fills and embankments to appropriate elevations so that finished contours indicated on the Drawings are obtained at final grading.

B. Material excavation at the site is generally considered usable for grading purposes, subject to the requirements set forth in this section of the specifications. Cuts and fills are not balanced. Additional fill required shall be provided at the expense of the Contractor. The Contractor shall remove excess excavated material from the site without additional cost to the Owner.

C. Existing pavement may be used in the construction of fills and embankments if the pavement is broken into pieces not greater than six (6) inches in their greatest dimension. Pavement shall not be used in the upper 18 inches of any fill or embankment. Existing pavement to be covered with two (2) feet or more of fill may be broken and left in place.

D. All materials placed in fills and embankments shall be free from rocks or stones larger than six (6) inches in their greatest dimension, sludge, brush, stumps, logs, roots, debris, and organic or other deleterious materials, and must be acceptable to the Village. No rocks or stones shall be placed in the upper eighteen (18) inches of any fill or embankment. Rocks or stones within the allowable size limit may be incorporated in the remainder of fills and embankments provided they are distributed so that they do not interfere with proper compaction.

E. After preparation of the fill or embankment site, the subgrade shall be leveled and rolled so surface materials of the subgrade will be as compact and well bonded with the first layer of the fill or embankment as specified for subsequent layers.

F. All fill and embankment materials shall be placed in approximately horizontal layers not to exceed eight (8) inches in uncompacted thickness. Material deposited in piles or windrows by excavating and hauling equipment shall be spread and leveled before compaction.

G. Each layer of material being compacted shall have the best practicable uniform moisture content to insure satisfactory compaction. The Contractor will be required to add water and harrow, disc, blade, or otherwise work the material in each layer to insure uniform moisture content and adequate compaction. Each layer shall be thoroughly compacted by rolling or other method acceptable to the Village to ninety-five percent (95%) of maximum density at optimum moisture content as determined by ASTM D698. If the material fails to meet the density specified, compaction methods shall be altered.

H. Wherever a trench passes through a fill or embankment, the fill or embankment material shall be placed and compacted to an elevation twelve (12) inches above the top of the pipe before the trench is excavated.

I. Fills and embankments that are placed over structures shall be placed and compacted by using methods that will not damage or overload the structure. Rubber tired equipment shall be used insofar as practicable. Individual items of equipment shall not have loaded weight in excess of 14,000 pounds and shall be operated so that no impact loads are imposed on the structures.

J. All tests to determine moisture and the compaction and density of materials used will be made by the Testing Laboratory, employed by the Contractor, at the expense of the Contractor, except as otherwise specified. The Contractor shall assist the Testing Laboratory in taking test samples and shall cooperate in the conducting of the tests, as he may be required without additional expense to the Owner.

K. All in - place field density tests that indicate additional compaction is necessary to meet the specified requirements shall be the financial obligation of the Contractor, and the costs of such tests will be deducted from payments to the Contractor. 20(6)

L. Two standard Proctor compaction tests (ASTM D698) shall be made on each type of fill material encountered. At least one (1) in-place field density shall be made for each 1,000 cubic yards of fill and embankment material placed.

M. Prior to placing any fill, the Contractor shall demonstrate to the satisfaction of the Testing Laboratory that the compaction method or methods, and the equipment to be used will provide the degree of compaction hereinafter specified.

N. The Contractor shall perform all items of excavation, and particularly fill, as early in the construction schedule as possible. The fill areas shall be allowed to settle or prove themselves during the period of building construction, and then be reshaped and regraded at the end of the construction schedule. Flooding, ponding, or jetting with water shall not be employed.

O. Minimum compaction densities for various fill areas shall be as follows (compaction densities indicated are expressed as percentages of maximum densities at optimum moisture in accordance with ASTM D698):

1.) Fill under lawn and planted areas, eighty-five percent (85%).

2.) Fill under surfaced areas, floors, areaways, curbs, parking areas, walls, terraces, steps, etc., ninety-five percent (95%).

3.) Top two (2) feet of fill under roadways, ninety-five percent (95%).

4.) Fills and backfills within four (4) feet of outside of walls, and fills not otherwise specified, ninety percent (90%).

P. After the installation of the foundation walls and removal of the forms, the excavation shall be cleaned of all trash and debris before application of damp proofing and placement of backfill. Symmetrical backfill loading shall be maintained and each layer compacted with mechanical tampers or other approved equipment. In placing backfill, special care shall be taken to prevent any wedge action, eccentric loading, or overloading of the structure by equipment used in compacting the backfill material and to prevent damaging the walls. Where subsoil drainage systems are required, backfill shall be placed so as to prevent any damage to the systems.

Q. Material shall be compacted when the moisture varies more than plus or minus 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. Compaction operations shall be suspended if necessary to accomplish this. Compaction operations shall be suspended when, in the Engineer's opinion, satisfactory results cannot be obtained because of rain or other unsatisfactory conditions.

19. CRUSHED ROCK OR GRAVEL FILLS

A. Crushed rock or gravel fills shall be placed on suitably prepared subgrades and compacted by vibration. Crushed rock or gravel shall be free from dust, clay, or trash and shall be graded 1-1/2 inch to No. 4 as defined in ASTM C33.

B. Where crushed rock or gravel fills are to be covered with concrete, the top surface shall be graded to the required subgrade and covered with polyethylene film.

20. INUNDATED SAND FILLS

A. Inundated sand fill may be used in lieu of crushed rock or gravel fill at locations where, in the opinion of the Village, inundation water will drain freely and without damaging adjacent property. Sand for inundated sand fills shall be clean with not more than twenty-five percent (25%) retained on a No. 4 sieve and not more than ten percent (10%) passing a No. 200 sieve. Inundated sand fills shall be placed on suitably prepared subgrades and sand shall be deposited in, or simultaneously with application of water so that the sand is kept inundated at all times. During placement, the sand shall be compacted to maximum density by using mechanical vibrating equipment.

B. Sand used shall be clean and washed. No inundated sand fill shall have a depth of less than four (4) inches.

21. TRENCH BACKFILL

A. All trench backfill above pipe bedding shall conform to the following requirements unless specifically noted to the contrary on the Contract Drawings. 20(7)

B. Compacted granular backfill of the gradation and type indicated on the Contract Drawings shall be required for the full depth of the trench above bedding in the following locations:

1.) Where beneath or within two (2) feet of pavements, surfacings, driveways, curbing, gutters, walks, or other surface construction or structures.

2.) Where the trench for one (1) pipe passes beneath the trench for another pipe, granular backfill for the lower trench shall be compacted to the level of the bottom of the upper trench.

C. The top twelve (12) inches of the trenches in streets, parking areas, driveways, or other paved areas shall be filled with approved road gravel or crushed stone as a temporary pavement, and shall be maintained level with adjoining pavement surfaces until the original type of pavement, or equal, is replaced.

D. In fills and embankments, compacted trench backfill shall be required.

E. Compacted backfill shall consist either of materials as specified on the Contract Drawings or, if not specified therein, shall consist of job excavated material, finely divided and free from debris, organic material, and stones larger than three (3) inches in greatest dimension. Masses of moist, stiff clay shall not be used. Job excavated materials shall be placed in uniform layers not exceeding six (6) inches in uncompacted thickness, and shall be carefully compacted to ninety-five percent (95%) of maximum density, at optimum moisture content as determined by ASTM D698, until there is a minimum cover of twelve (12) inches over the installed pipe. The additional backfill shall be placed in uniform eight (8) inch layers and also compacted to a density of ninety- five percent (95%). Any trench improperly filled, or where settlement occurs, shall be reopened to the depth required for proper compaction, then refilled and compacted, with the surface restored to required grade. This corrective work shall be performed as required at the Contractor's expense. Water settlement of earth backfill will not be permitted.

F. At the option of the Contractor, inundated sand may be installed in lieu of compacted backfill in any of the above locations where, in the opinion of the Village, use of water for this purpose would cause no damage to adjacent property or buried utilities.

G. Sand for inundated sand backfill shall be clean with not more than twenty-five percent (25%) retained on a No. 4 sieve and not more than seven percent (7%) passing a No. 200 sieve and shall have an effective size between 0.10 mm and 0.30 mm. Sand shall be deposited in, or placed simultaneously with application of water so that the sand is inundated during compaction. During placement, the sand shall be compacted by a mechanical probe type vibrator. Inundated sand shall be compacted to seventy percent (70%) relative density as determined by ASTM D2049.

H. Compaction of trench backfill above pipe bedding in locations other than those specified will not be required to the extent necessary to prevent future settlement. Non-compacted trench backfill shall be jetted to minimize future settlement unless directions to the contrary are issued in writing by the Engineer. Jetting shall be considered incidental to the Contract.

I. Uncompacted earth backfill material to be placed above beddings shall be free to brush, roots more than two (2) inches in diameter, debris, and junk, but may contain rubble and detritus from rock excavation, stones, and boulders, in certain portions of the trench depth.

J. Uncompacted backfill material above beddings may be placed by any method acceptable to the Village, which will not impose excessive concentrated or unbalanced loads, shock, or impact on, and which will not result in displacement of installed pipe.

K. Compact masses of stiff clay or other consolidated material more than one (1) cubic foot in volume shall not be permitted to fall more than five (5) feet into the trench unless cushioned by at least two (2) feet of loose backfill above pipe bedding.

L. No uncompacted trench backfill material containing rocks, or rock excavation detritus, shall be placed in the upper eighteen (18) inches of the trench except with specific permission of the Village, nor shall any stone larger than eight (8) inches in its greatest dimension be placed within three (3) feet of the top of pipe. Large stones may be placed in the remainder of the trench backfill only if well separated and so arranged that no interference with backfill settlement will result.

22. STRUCTURAL BACKFILL

A. After completion of structures and prior to backfilling, the Contractor shall remove all forms and clean the excavation of 20(8) trash and debris. Backfill around and outside of structures shall be deposited in layers not to exceed eight (8) inches in uncompacted thickness and mechanically compacted, using platform-type tampers, to at least ninety-five percent (95%) of maximum density at optimum moisture content as determined by ASTM D698. Compaction of structure backfill by rolling will be permitted provided the desired compaction is obtained and damage to the structure is prevented. Compaction of structure backfill by inundation with water will not be permitted.

B. Material for structure backfill shall be composed of earth only and shall contain no wood, grass, roots, broken concrete, stones, trash, or debris of any kind. No tamped, rolled, or otherwise mechanically compacted backfill shall be deposited or compacted in water.

C. All backfill material shall consist of loose, damp (not wet) earth having moisture content such that maximum density of the compacted soil will be obtained. Moisture content shall be distributed uniformly and water for correction of moisture content shall be added sufficiently in advance that proper moisture distribution and compaction will be obtained.

D. Particular care shall be taken to compact structure backfill which will be beneath pipes, drives, roads, parking areas, walks, curbs, gutters, or other surface construction or structures. Wherever a trench passes through structure backfill, the structure backfill shall be placed and compacted to final ground surface elevation for pipe supported on brackets, and to an elevation twelve (12) inches above the top of the pipe for all other pipe before the trench is excavated. Compacted areas, in each case, shall be adequate to support the item to be constructed or placed thereon.

23. EXCESS EXCAVATED MATERIALS

A. Insofar as needed, suitable excavated materials shall be used in fills and embankments shown on the Drawings. Excess excavated material which, in the Owner's opinion, is suitable for cover material shall be stockpiled for the Owner either on the site or as directed in the SPECIAL CONDITIONS.

B. All unused suitable excess excavated materials together with all excavated sludge, debris, junk, stones, logs, stumps, roots, and other unsuitable materials shall be removed from the site and disposed of by, and at the expense of, the Contractor. The unused suitable excavated material shall be disposed of, by the Contractor, legally and at no additional cost to the Owner.

24. FINAL GRADING

A. After other outside work has been finished, and backfilling and embankments completed and settled, all areas on the site of the Work which are to be graded shall be brought to grade at the indicated elevations, slopes, and contours. Use of graders or other power equipment will be permitted for final grading and dressing of slopes, provided the result is uniform and equivalent to hand work. All surfaces shall be graded to secure effective drainage. Unless otherwise shown, a slope of at least two percent (2%) shall be provided.

B. Grading and surfacing shall be completed to the satisfaction of the Village.

25. SETTLEMENT

A. The Contractor shall be responsible for all settlement of backfill, fills, and embankments that may occur within one (1) year after final completion of the Contract under which the Work was performed.

B. The Contractor shall make, or cause to be made, all repairs or replacements made necessary by settlement within thirty (30) days after notice from the Village or Owner.

26. SOIL BORINGS

Soil Borings, if available from owner, shall be included in Section 25.
