203Excavation and Embankment

203.01Description. This work consists of excavation and embankment required for

roadways, ditches, channel changes and borro w material, preparation of subgrades and foundations, construction of embankments and other utilization or disposal of materials excavated, and the compaction and dressing of excavated areas and embankments. This work shall also consist of any required site grading in accordance with the details in the plans and/or as directed by the Engineer. The work of excavatio n for structures is covered separately under Section 206 and not included under this section.

.1--Unclassified Excavation. Unclassified excavation will consist of all

excavation materials of whatever character encountered in the wo rk except for those classes of excavation for which separate pay items are provided.

.2--Rock Excavation. When shown as a pay item, rock excavation will consist of

material that cannot be excavated without blasting and shall also include large boulders and detached stones having volumes of one-half cubic yard or more. The use of the words "rock," "boulders," "stone," or synonyms of these words appearing elsewhere on the plans, soil profile or these specifications does not imply that these materials may be included under this classification unless so indicated in the contract proposal. The Contractor shall immediately notify the Engineer when rock excavation is encountered during the progress of the work so the necessary measurements may be made for determining the volume removed. 106 Section 203 Section 203

.3--Muck Excavation. Muck excavation will consist of the excavation, removal

and disposal of natural deposits of soils and organic matter in accordance with the provisions of Subsection 203.03.7. Muck excavation shall not be identified by visual means but will be sampled and tested, at a frequency determined by the Engineer, to verify its classification. Muck excavation is defined as a saturated soil having an organic content of at least six percent (6%) as determined by Mississippi Test Method MT-29, or AASHTO T 267. It is the intent that all areas of muck excavation will be located and defined during the design phase of a project. However, if additional areas of questionable material are found during construction, the material shall be tested to see if it is a saturated soil having an organic content of six percent (6%) or more be fore it is considered muck. If the material is defined as a muck, based on testing, the method of removal should not be an issue and the material should be paid for as 203-D, Muck Excavation. Excavated material not meeting the hereines tablished requirements for classification as muck excavation shall be used , measured and paid for under the pay item in which the material is being used. In extreme cases, in non-organic areas where all efforts to drain the area and/or dry the material have proved unsuccessful, the Project Engineer, in consultation with the District Materials Engineer and District Construction Engineer, shall make the determination as to whether the material will be classified as muck excavation or unclassified excavation. Removal of muck excavation shall be in accordance with the requirements of Subsection

104.05

.4--Borrow Excavation. Borrow excavation will consist of approved material

required for the construction of embankments or other portions of the work and shall be obtained from approved sources outside the right-of-way except as provided in Subsection 203.03.3. Unless otherwise provided in the contract, the Contractor shall make arrangements for obtaining borrow and pay all costs involved. Contractor- furnished borrow shall meet the requirements of Subsections 106.02.2 and 703.21.

.5--Channel Excavation. When shown as a pay item, channel excavation will

consist of excavation and disposal of all material from widening, deepening or straightening of an existing channel, or construction of a new channel. The Contractor shall furnish a disposal area unless otherw ise provided in the contract. Material designated as channel excavation and used in the roadbed or other required embankment construction will be measured for payment as channel excavation only.

.6--Excess Excavation. When shown as a pay item, excess excavation will

consist of excavation that cannot be satisfactorily used or disposed of within the right-of- way. Exclusive of muck excavation, excess excavation may include any type, kind, or class of excavation that the Engineer determines must be removed from the right-of-way. It will not include any excess caused by the Contractor importing too much excavation from sources outside the roadway structure; in such case, the excess excavation shall be removed from the right-of-way without cost to the State. Unless otherwise indicated in the contract, the Contractor shall provide a disposal area for 107 Section 203 Section 203 excess excavation. Removal of excess excavation shall be in accordance with the requirements of Subsection

.7--Surplus Excavation. When shown as a pay item, surplus excavation will

consist of excavation within the right-of-way that is in excess or unsuitable for embankments but can be satisfactorily used or disposed of within the right-of-way.

203.02Blank

203.03Construction Requirements

.1--General. Excavation and embankment operations may be started at the

location and in the sequence approved by the Engineer when:

Excavations and embankments shall be finished to reasonably smooth and uniform surfaces. No material shall be wasted without permission of the Engineer. Excavation operations shall be conducted in a manner that material outside the construction limits will not be unnecessarily disturbed. No excavation or embankment shall be placed while frozen or placed on frozen materials. Where plating with topsoil is contemplated, either in cut or fill sections, appropriate adjustment shall be made in the graded section during construction so that the finished section after plating will conform to the typical sections shown on the plans. Unless otherwise specified, rock larger than three inches shall be removed from the roadbed to a minimum depth of eight inches below subgrade and backfilled with material designated on the plans or approved by the En gineer. Care shall be taken that undrained pockets are not left in the surface of rock. Rock removed more than 12 inches below subgrade will not be measured for payment and backfilling in excess of 12 inches will be at the expense of the Contractor. Removal of boulders and subsequent backfilling are excluded from the 12-inch limitation. Borrow material should no t be placed until excavation from the roadway has been utilized as shown on the plans. Excess material determined to have been caused by the Contractor importing too much excavation from sources outside the roadway shall be removed from the right-of-way in accordance with Subsection 104 .05 unless permission is given by the Engineer that the material may be disposed of within the right-of-way. In either case, the volume of excess material will be measured by the method deemed most appropriate by the Engineer under the provisions of Subsection 109.01 and deducted from measured quantities. The Contractor shall not excavate beyond the dimensions and elevations established or approved, and no material shall be moved prior to the staking out and cross-sectioning of the site. 108 Section 203 Section 203 If borrow material is to be measured for payment in its original position (FM), the finished borrow areas shall be left in a condition suitable to accurately measure the material used. Additional requirements shall be those applicable conditions governing the use of local materials as set out in Section 106. Obliteration of old roadways shall include all operations necessary to incorporate the old roadway into the new roadway or into the surrounding right-of-way in a way that will provide a pleasing appearance from the new roadway. Unless other pay items are provided, roadway obliteration will be paid for as unclassified excavation. When excavating operations encounter the remains of prehistoric dwelling sites or other artifacts of historical or arch eological significance, the oper ations shall be temporarily discontinued. The Engineer will contact appropriate authorities to determine their significance and appropriate disposition. When directed by the Engineer, the Contractor shall excavate the site in a manner to preserve the artifacts encountered, or aid in the determination of significance and disposition, and when ordered, shall remove them for delivery to the custody of the proper State authorities. Such excavation and removal will be considered and paid for as Extra Work. If excavation to grade results in a foundation, subgrade, or slope of unsuitable soil, the Engineer may require the Contractor to remove unsuitable materials and backfill to the required grade with approved material. Slides or other soil failures shall be removed by the Contractor unless their removal is waived by the Engineer. The Contractor shall conduct operations in such a way that the E ngineer can take the necessary cross sections before backfill is placed. The Engineer may designate as unsuitable those soils that, at the proper moisture content, cannot be processed to the required density and stability. All unsuitable material shall be disposed of as specified or directed. When the Engineer orders or the contract requires excavation to be handled more than one time prior to final placement, such as topsoil to be stockpiled and reserved for later use, payment will be made at the contract unit price for the class excavation involved for each handling approved by the Engineer, or it will be paid as another item of work for the final handling when so specified. The topsoil shall be dressed vertically with a dozer or other tracked equipment.

.2--Topsoil. Where the salvaging and stockpiling of topsoil is specified, this

operation shall be completed before beginning excavation of the underlying material.

.3--Borrow Excavation from Within the Right-of-Way . When the contract

indicates borrow excavation to be paid for as final measure-embankment (FME), the plans may also identify certain estimated excavation volumes by the symbol ESFE (Estimated State Furnished Excavation). Suitable quantities of ESFE may be used by the Contractor without charge in the construction of embankments to be measured FME. Quantities of ESFE shown on the plans are for the Contractor's information only and may vary or may be varied by the Engineer. The change in quantity shall not be cause for additional compensation. 109 Section 203 Section 203 Excavation designated as ESFE is required to be performed and will not be measured in its original position. ESFE suitable for use in embankment or other features of the work shall be used and will be included in measured quantities of borrow excavation (FME). Any materials indicated as ESFE that are fo und to be unsuitable shall be removed and disposed of as provided elsewhere in the contract.

.4--Construction of Bridge Approaches . The construction of "spill through"

embankments and approaches shall be the responsibility of the grading Contractor. The existence of a separate contract awarded for bridge construction will not alter this

responsibility.

The grading Contractor shall construct the bridge approaches to subgrade elevation and

extending a minimum of 100 feet from each bridge end as soon as practicable. All bridge

end slopes shall be finished to the lines and grades specified except the allowable

tolerance for initial construction of bridge end slopes to be paved is plus six inches.

The bridge Contractor shall drive the piling through the fill, complete the end bents, end

spans, and slope paving as soon as practicable after the bridge end fills have been placed

in order that the grading may be completed by the grading Contractor. The bridge

Contractor is responsible for the final shaping of the "spillthrough" embankment for

placement of slope paving or riprap.

.5--Excavation Operations. Excavation operations shall be so conducted as to

minimize the loosening of materials outside the required slopes or below the indicated

grade. No payment will be made for the removal, disposal or replacement of material

determined to be loosened or undercut through carelessness or negligence on the part of

the Contractor. Neither will payment be made for excavation that is used for purposes

other than designated except as provided in Subsection 104.06.

When practicable, excavation and disposal of the material shall be conducted in such a

manner that the most suitable material will be placed in the top courses of embankments.

Also, adequate drainage that will conform to the finished drainage system shall be

maintained.

All earth cut slopes shall be dressed to smooth and uniform surfaces to conform to the

specified sections. The allowable horizontal tolerance at subgrade elevation will be five-

tenths of a foot. The allowable tolerance from staked cut slopes will be plus or minus

five tenths of a foot horizontally for each 10 feet of depth. Allowable vertical tolerances

at subgrade elevation shall be in accordance with the tolerances set out in Section 321.

Care shall be taken to avoid overshooting of material when blasting. All rock cut slopes

shall be left with a reasonably uniform surface, and all loose, shattered or overhanging

rock shall be removed.

.6--Muck Excavation. The depth and width of muck excavation will normally be

shown on the plans. The excavation and subsequent basement soil formation shall be

completed as soon as practicable in order to obtain maximum consolidation prior to final

shaping of the subgrade and subsequent construction of the pavement structure. When

directed by the Engineer, other unsatisfactory foundation material beneath or

immediately adjacent to the muck shall be removed and disposed of as muck excavation.

110

Section 203 Section 203

Excavation of muck shall proceed ahead of backfilling or embankment operations for the

full width and depth shown on the plans or as directed.

Placing of embankment material in the excavated area by backdumping may be permitted

when the Engineer determines this method of placement to be satisfactory. In this case,

placement shall immediately follow the muck removal, and where deemed desirable, the

fill shall be constructed forward in a wedge shape with as much of a surcharge above

grade as practicable to afford maximum displacement of the remaining muck. Pressure

developed on the advancing toe of the embankment by the displaced muck shall be

relieved by excavating and removing the muck. Otherwise, embankment construction

shall be performed in accordance with the provisions of Subsection 203.03.8.

The Contractor shall take necessary precautions to ensure that stream channels and

drainage ditches will not be filled by movement of muck. Displaced materials adjacent to

the roadway shall be leveled or disposed of as specified. In any case, the material shall

be left in such a manner that it will not present an unsatisfactory appearance, interfere

with essential drainage or prevent proper embankment formation.

.7--Disposal of Unsuitable, Surplus, Channel and Excess Excavation. All

material encountered in excavation within the right-of-way that is unsuitable for use in

the work shall be removed and disposed of as specified in the contract or as directed.

Unsuitable material shall be understood to be any material that, at the proper moisture

content, cannot be processed to the required density and stability.

The Contractor will be paid for unsuitable material ordered excavated and disposed of

and the required backfill material at the respective contract prices except when the

unsuitable material was placed under the contract.

Unless otherwise specified, the Contractor shall provide at no additional costs to the State

the location for the disposal of muck and excess excavation and shall furnish the

Engineer with two signed copies of the release as provided in Subsection 104.05.

Removal of muck and excess excavation shall be in accordance with the requirements of

Subsection 104.05.

Surplus excavation as defined in Subsection 203.01.7 shall be used for widening of

embankments, flattening slopes or at other locations within the right-of-way for the

purpose indicated. If there is more surplus excavation than can be effectively used within

the right-of-way, the Engineer may reclassify the excavation as excess excavation as

defined in Subsection 203.01.6 when the contract contains a bid item for excess

excavation or order its disposal as extra work.

Unless specified for use in embankments, channel excavation may be used to fill old

channels when so designated on the plans and to fill washes and gullies or wasted as

directed by the Engineer. It shall be spread and leveled or otherwise shaped to blend with

the adjacent terrain and shall not obstruct drainage, interfere with the property rights of

others or present an unsatisfactory appearance.

.8--Embankment Construction

.8.1--General. Embankment construction shall consist of constructing roadway

111

Section 203 Section 203

embankments, dikes, placing and compacting of approved material where unsuitable

material has been removed, backfilling of structures where not otherwise provided for

and placing and compacting embankment material in holes, pits or other depressions.

This work shall also consist of preparation of the areas upon which embankments are to

be constructed. Only approved materials shall be placed in embankments and backfills.

Unsuitable or perishable materials such as rubbish, sod, brush, roots, logs, stumps after

removal, heavy vegetation, sawdust, etc., shall not be incorporated in embankments.

Rocks, broken concrete, or other solid material shall not be placed in embankment areas

where piles are to be driven.

Special materials for inundated areas, filter beds, etc., or special backfill may be specified

elsewhere in the contract.

.8.2--Preparation of Embankment Areas. Preparation of embankment areas

shall be in accordance with one or a combination of the following procedures:

directed by the Engineer and compacted to the density for the design soil portion

of embankments. The material excavated from the undercut, if suitable, shall be

used in other portions of the work. The undercut at each grade point shall be

approximately three feet below subgrade. The undercut shall be extended a

sufficient distance into the cut to provide an undercut grade at the point of

intersection with the subgrade of not less than three feet below natural ground.

Approved undercut will be measured for payment as excavation.

less than three feet below subgrade, the old road shall be scarified as directed.

The scarified material shall be compacted to the density specified for the design

soil portion of the embankment prior to placing additional material.

unsuitable soil shall be removed from the surface upon which the embankment

is to be constructed when the height of the embankment to subgrade will be

three feet or less. The cleared surface shall be thoroughly mixed by plowing,

scarifying or disk-harrowing to a depth of at least six inches. The area shall then

be compacted to the density specified for the design soil portion of the

embankment.

The removed vegetation and unsuitable soil shall be disposed of as directed. No

measurement for payment will be made unless the Engineer requires that the

material be loaded and hauled for use or disposal in another area. In this case,

measurement for payment will be made as provided in Subsection 203.04 and

haul will be paid as provided in Section 205. No direct payment will be made for

the plowing, scarifying or disk-harrowing.

feet, all material determined by the Engineer to be unsuitable as a foundation of

the embankment shall be undercut and disposed of as directed. All sod on other

areas shall be thoroughly disk-harrowed before construction of the embankment.

Approved undercut will be measured for payment as excavation and haul will be

paid as provided for in Section 205. No direct payment will be made for the

112

Section 203 Section 203

disk-harrowing.

hillsides, the slopes that are steeper than 6:1 shall be continuously benched as

the new work is constructed on the slope. Benching shall be of sufficient depth

and width to permit operation of the construction equipment. Each horizontal

cut shall begin at the intersection of the original ground or slope and the vertical

side of the previous cut. Suitable material thus cut out shall be re-compacted

along with the new embankment material and will not be measured for payment.

.8.3--Embankment Formation. After the area has been prepared as specified, the

embankment shall be constructed in full-width layers parallel to the finished grade.

Except as herein provided, the non-compacted thickness of each layer shall not exceed

eight inches and shall be spread, shaped and compacted to the required density and

stability. The completed embankment shall conform to the line, grade, and cross-section.

The required stability in embankment construction shall be that which the Engineer

determines can be reasonably obtained at the proper moisture content for the material

being placed. Sponginess, shoving or other displacement under heavy equipment will be

considered prima facie evidence of the lack of stability.

Direct casting or similar methods will not be permitted unless authorized in writing by

the Engineer. When direct casting is authorized, all material shall be moved from the

point where it is deposited, spread and compacted in uniform layers as specified herein.

.8.4--Basement Soils. Reference is made to Figure 1 at the end of Subsection 101

regarding basement soils. In low, swampy ground that will not support the weight of

hauling equipment, the Engineer may permit the bottom portion of the embankment to be

built in a uniformly distributed layer of sufficient thickness to support the construction

equipment. However, this method will not be permitted in any portion of the

embankment within three feet of the subgrade.

Where the embankment material is from an inconsistent soil deposit, construction shall

be performed so as to eliminate pockets or strata of varying materials. Each layer shall

be disk-harrowed and heavily bladed for its full depth; or moved from its position of

deposit by appropriate equipment; or processed by other means to the extent necessary to

eliminate pockets or stratification of the embankment materials. The layer shall then be

shaped and compacted in accordance with these specifications.

Rock shall be distributed over the embankment area to avoid bridging, nests or pockets,

and all voids shall be completely filled with earth or stone fragments and compacted.

Where only occasional boulders are encountered, they shall be placed near the outer

slopes in lower portions of the embankment.

Where the excavated material consists predominately of rock fragments of sizes that

cannot be placed in layers of the thickness specified without crushing, pulverizing or

further breaking down of pieces resulting from excavation methods, the material may be

placed in layers not exceeding the thickness of the approximate average size of the rocks,

but in no case to exceed three feet. The balance of the embankment shall be composed of

suitable material placed in layers not exceeding eight inches in loose thickness and

113

Section 203 Section 203

compacted as specified.

.8.5--Design Soils. Reference is made to Figure 1 at the end of Subsection 101

regarding design soils. Each layer of the design soil shall be disk-harrowed and heavily

bladed for its full depth, or processed by other approved means to the extent necessary to

provide a layer of material reasonably uniform in character. Each layer shall then be

shaped and compacted in accordance with these specifications.

.8.6--Backfill and Embankment Formation Adjacent to Structures

Backfilling around structures shall not start until permission has been granted by the

Engineer as referenced in Subsection 601.03.6.3. After approval is given to proceed, the

work shall be performed under the supervision of the Engineer or the Engineer’s

designated representative.

Material used shall be suitable material obtained from structure excavation, roadway and

drainage excavation or other designated material. The material shall be approved before

placement and shall be the best available from the source. It shall preferably be sandy or

loamy non-plastic material and free from large lumps, clods, rock or other objectionable

matter. Adequate provision shall be made for thorough drainage of all backfilling.

The backfill material shall be deposited in uniform and parallel layers not to exceed eight

inches of loose material on each side of box bridges, culverts or other structures. Each

layer shall be processed by approved methods for its full depth and to the extent

necessary to provide a layer of material reasonably uniform in character and shall be so

placed and compacted that drainage of the layer will be away from both the longitudinal

and the transverse axes of the structure. In addition, the backfill for abutments, retaining

walls, wing walls or other structures or sections thereof shall be built in layers with each

layer being constructed for the full length of the unit and special precaution shall be taken

to prevent any wedging action against the structure.

The material for each layer shall be uniformly compacted with approved mechanical

equipment or self-powered mechanical tampers to not less than the density required in the

adjacent embankment. The work shall be conducted so as to form a berm of compacted

soil of sufficient width on each side of the structure. The berm at the top of the structure

shall be at least six feet in width. The slopes of the backfill shall not be steeper than 2:1

at any point. Unless otherwise specified, backfilling shall continue as applicable to the

level of the original ground or to an elevation at least one foot above the top of the

structure or to the top of the graded section when less than one foot of cover is provided.

The work shall be conducted in a manner that the Engineer can make the necessary tests

for compaction as the work progresses.

The Contractor shall repair, restore with new work or make good without extra

compensation all damage to the structure as a result of the backfilling operation.

Payment for this construction shall be included in the contract unit price for the material

with which backfill is made.

.8.7--Compaction of Embankments. All embankment material shall be at the

moisture content determined to be proper for the particular material being placed so that

the resulting work will be both dense and stable.

114

Section 203 Section 203

It shall be the Contractor's responsibility to maintain the proper moisture content during

compaction operations and the Engineer may require additional moisture or drying as

necessary without additional compensation.

The material shall be compacted until the required density, determined in accordance

with Subsections 700.03 and 700.04, has been attained and the embankment is stable.

Acceptance of compaction will be on a lot basis. A lot size will be based on the

Contractor's hourly production rate as set out in Department's SOP.

For basement and design soils, the required density shall be 95.0 percent and 98.0

percent, respectively. If a density test is within minus two percent (-2.0%), 93.0 to 95.0%

or 96.0 to 98.0%, of the required density, a verification test will be performed and the

average of the two tests will be the test value for the lot. The lot shall be rejected if this

test value does not meet the required density (95.0 or 98.0%). If the original test value

exceeds minus two percent (-2%) of the required density, no verification test will be

performed and the lot shall be rejected.

Acceptance of compaction for structural backfill will be considered a separate frame of

work. The backfill at each structure up to a depth of five feet will be considered a lot.

For long structures, the Engineer may specify that the backfill be divided into smaller

lots. Each lot will be divided into four approximately equal sublots with two density tests

taken at random on each side of the structure. The single test and the lot average shall

conform to the required densities set forth above for basement soils or design soils as

applicable.

The Contractor shall make allowance for shrinkage and compaction in the construction of

embankment.

.8.8--Tolerances. The tolerances shown below as allowable shall not prevent the

work from meeting the requirements of Subsection 105.03.

Allowable vertical tolerances for design soils at subgrade elevation shall be in accordance

with the tolerances set out in Section 321.

The allowable horizontal tolerance at subgrade elevation will be five-tenths of a foot.

The allowable tolerance from staked slopes on fills will be plus or minus five-tenths of a

foot horizontally for each 10 feet of fill height except where surplus excavation is

required or permitted by the Engineer for widening embankments or flattening slopes. In

these cases tolerances will be modified accordingly.

.9--Site Grading. Site grading shall consist of excavating or shaping foreslopes,

backslopes, or areas shown on the plans to the satisfaction of the Engineer. When site

grading is performed and the yield of material from shaping the designated area is in

excess of the material needed, such material will be removed and disposed of as directed

by the Engineer. Payment of removed material will be made at the contract price for the

class excavation involved.

Clearing and grubbing, if required, shall be included in the bid item for clearing and

grubbing. If no bid item for clearing and grubbing is included in the contract, it shall be

115

Section 203 Section 203

included in the contract unit price for site grading.

The equipment used to site grade shall be capable of grading the site to a uniform and

smooth surface as directed by the Engineer.

.10--Maintenance of Earthwork. The Contractor shall satisfactorily maintain all

portions of the work until release of maintenance by the Engineer as referenced in

Subsections 105.14, 105.15, 105.16 and 107.17. The Contractor shall replace, restore or

reconstruct without extra compensation all portions, including materials, determined by

the Engineer to have been displaced or damaged due to carelessness or negligence.

Carelessness or negligence may include, but not be limited to, improperly maintained;

inadequate drainage; failure to remove forms or obstructions; failure to properly

prosecute and complete work within the specified time; neglecting to establish erosion

control items in accordance with the provisions of Subsection 107.22 and Section 210 or

other avoidable causes for displacement or damages.

203.04Method of Measurement. Items of excavation listed in the proposal will be

measured as set forth herein, unless otherwise stipulated.

.1--Unclassified, Rock, Muck, Channel, Excess and Surplus Excavation

These items will be measured by the cubic yard final measure (FM) or loose vehicular

measure (LVM) in accordance with Subsection 109.01. The unit of measurement for

each item will be shown on the proposal bid sheets. Excavation identified as ESFE will

not be measured for payment as excavation except as provided herein.

Excavation identified as ESFE that is unsuitable for placement in the designated roadway

prism may be used to construct berms, flatten slopes, wasted on the right-of-way or

disposed of by the Contractor off the right-of-way as directed by the Engineer and will be

measured for payment under Pay Item No. 203-A, Unclassified Excavation. When the

contract does not include a bid price for unclassified excavation, the ESFE will be

measured for payment under Pay Item No. 203-EX, Borrow Excavation (ESFE) (FM)

(AH), per cubic yard at a unit price equal to 75 percent of the contract unit price for

contractor furnished borrow excavation.

.2--Borrow Excavation-State Furnished. Borrow excavation will be measured

in accordance with Subsection 109.01 by the cubic yard FM, FME or LVM. The unit of

measure will be shown on the proposal bid sheets. When measurement is by FME, it will

include excavation identified as ESFE which has been incorporated into the embankment.

.3--Borrow Excavation-Contractor Furnished. Contractor furnished borrow will

be measured in accordance with Subsection 109.01 by the cubic yard FME or LVM. The

unit of measure will be shown on the proposal bid sheets. When measurement is by

FME, it will include excavation identified as ESFE which has been incorporated into the

embankment.

Undercut required by the Engineer prior to placement of embankment material that is

suitable for placement in other furnished portions of the embankment will be measured

for payment as contractor borrow excavation.

Undercut that is unsuitable for placement in the designated roadway prism may be used

elsewhere and measured for payment as provided in Subsection 203.04.1 for unsuitable

116

Section 203 Section 203

material identified as ESFE.

.4--Haul. Haul of excavation, when authorized for payment, will be measured in

accordance with Subsection 205.04. Unless otherwise provided, haul will not be

measured for channel excavation, muck excavation or contractor furnished borrow

excavation. Nor will haul be measured for payment of the other excavation items when

the pay item description contains the symbol "AH" for absorbed haul.

.5--Site Grading. Site grading, complete and accepted, will be measured by the
