Section 106
Section 106. — ACCEPTANCE OF WORK
106.01 Conformity with Contract Requirements. Follow the requirements of FAR Clause 52.246-12
Inspection of Construction.
References to standard documents and test methods of AASHTO, ASTM, GSA, and other recognized
standard authorities refer to the documents and methods in effect on the date of the Invitation for Bids
(IFB) or Request for Proposal (RFP).
Use the FLH, Field Materials Manual (FMM), Appendix B: FLH Test Methods in effect on the date of the
IFB or RFP. Electronic copies of the FLH Test Methods and FHWA forms can be downloaded from:
Specification limits, tolerances, test results, and related calculations are according to ASTM E29, Absolute
Method.
Perform work to the lines, grades, cross-sections, dimensions, and processes or material requirements
shown in the contract.
Incorporate manufactured material into the work according to the manufacturer’s recommendations or to
these specifications, whichever is stricter.
When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, and pipe
conduits that are identified by gauge, density, or section dimensions) the identification will be considered
to be nominal masses or dimensions. Unless specific contract tolerances are noted, established
manufacturing tolerances will be accepted.
Plan dimensions and contract specification values are the values to be strived for and complied with as the
design values from which deviations are allowed. Perform work and provide material that is uniform in
character and reasonably close to the prescribed value or within the specified tolerance range. The purpose
of a tolerance range is to accommodate occasional minor variations from the median zone that are
unavoidable for practical reasons.
The Government may inspect, sample, or test work before final acceptance of the project. If the
Government tests work, copies of test reports are furnished to the Contractor upon request. Government
tests may or may not be performed at the work site.
If Government testing is performed on work, the result will be used for acceptance purposes under
Subsection 106.04.
Do not rely on the availability of Government test results for process control.
Acceptable work conforming to the contract will be paid for at the contract unit bid price. Four methods of
determining conformity and accepting work are described in Subsections 106.02 through 106.05. The
primary method of acceptance is specified in each Section of work, but work may be rejected if it is found
not to comply with the contract.
25
Section 106
For work that is evaluated and accepted under Subsection 106.05, if Contractor testing and inspection is
verified by the Government, the Contractor’s results may be used by the Government to evaluate work
for acceptance. Contractor data will be verified using the F- and t-test statistics in comparison to
Government test results at a significance level of 0.01. If the Contractor’s data is not verified and the CO
determines it to be appropriate, the Government will perform tests associated for that discrete portion of
work. In this situation, the Government test results will control in determining the acceptability and pay
factor of the work.
Remove and replace work that does not conform to the contract, or to prevailing industry standards where
no specific contract requirements are noted, at no cost to the Government.
As an alternative to removal and replacement, the Contractor may submit a written request to:
(a) Have the work accepted at a reduced price; or
(b) Perform corrective measures to bring the work into conformity.
Include supporting rationale and documentation in the request. Include references or data justifying the
proposal based on an evaluation of test results, effect on service life, value of material or work, quality,
aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming
work.
106.02 Visual Inspection. Acceptance is based on visual inspection of the work for compliance with the
contract and prevailing industry standards.
106.03 Certification. For material manufactured off-site, use a manufacturer with an ISO 9000
certification or an effective testing and inspection system. Require the manufacturer to clearly mark the
material or packaging with a unique product identification or specification standard to which it is
produced.
Other than references in or to the FAR or Federal Law, when these Standard Specifications or Special
Contract Requirements reference certifications, certificates or certified documents, equipment or
individuals; these references refer to documentation of non-regulatory, peripheral contract requirements
that are required to be validated by an individual or organization having unique knowledge or
qualifications to perform such validation.
Check certifications before incorporating the material into the work to ensure that the requirements of
the contract have been met. Mark the certifications with the following information:
Project number and name;
Pay item number and description;
Contractor’s signature; and
Date.
Material accepted by certification may be sampled and tested. If material is determined not to conform
with the contract, the material will be rejected whether in place or not.
26
Section 106
One of the following certifications may be required:
(a) Production certification. Material requiring a production certification is identified in the
Acceptance Subsection of each Section. Submit a production certification from the manufacturer for
each shipment of material. Include the following:
(1) Date and place of manufacture;
(2) Lot number or other means of cross-referencing to the manufacturer’s inspection and testing
system; and
(3) Substantiating evidence that the material conforms to the contract quality requirements as
required by FAR 46.105(a)(4), including the following:
(a) Test results on material from the same lot and documentation of the inspection and testing
system;
(b) A statement from the manufacturer that the material complies with the contract; and
(c) Manufacturer’s signature or other means of demonstrating accountability for the
certification.
(b) Commercial certification. Submit one commercial certification for similar material from the same
manufacturer.
A commercial certification is a manufacturer’s or Contractor's representation that the material
complies with the contract. The representation may be labels, catalog data, stamped specification
standards, or supplier's certifications indicating the material is produced to a commercial standard or
specification.
106.04 Measured or Tested Conformance. Perform necessary measurements and tests to ensure work
complies with the contract.
Use prevailing industry standards in the absence of contract requirements or tolerances.
Submit measurements, tests, and supporting data for acceptance.
106.05 Statistical Evaluation of Work and Determination of Pay Factor. Statistical evaluation of work
is a method of analyzing inspection or test results to determine conformity with the contract. The work will
be accepted as follows:
(a) General. For work evaluated based on statistical evaluation, both the Government and Contractor
assume some risk.
The Government's risk is the probability that work of a rejectable quality level is accepted. The
Contractor's risk is either the probability that work produced at an acceptable quality level (AQL) is
rejected (α) or the probability that the work produced at the AQL is accepted at less than the contract
unit bid price (α100).
27
Section 106
Acceptable quality level is the lowest percentage of work within the specification limits that is
considered acceptable for payment at contract unit bid price. There are two categories:
Category I is based on an AQL of 95 percent.
Category II is based on an AQL of 90 percent.
In both cases, the Contractor's risk (α100) is 5 percent and the risk of rejection (α) is significantly
lower.
As an incentive to produce uniform quality work and to offset the Contractor's risk, a final payment
greater than the contract unit bid price may be obtained under certain conditions.
The quality characteristics to be evaluated, sampling frequency, sampling location, test methods, and
category are listed in the Acceptance Subsection of each Section. The following applies:
(1) Lot size. A lot is a discrete quantity of work to which the statistical evaluation procedure is
applied. A lot normally represents the total quantity of work produced. More than one lot may
occur if changes in the target values, material sources, or job-mix formula are requested in
writing and approved.
(2) Sampling frequency. The frequency rate shown normally requires at least 5 samples. The
minimum required to perform a statistical evaluation is 3 samples. The maximum obtainable pay
factor with 3, 4, or 5 samples is 1.01. At least 8 samples are required to obtain a 1.05 pay factor.
If the sampling frequencies and quantity of work would otherwise result in fewer than 8 samples;
submit a written request to increase the sampling frequency to provide for at least 8 samples.
Submit the request to increase the sampling frequency at least
48 hours before beginning
production. An increase in the sampling frequency may result in a reduced pay factor.
(3) Sampling location. The exact location of sampling will be determined by the CO based on
random numbers.
(4) Specification limits. The specification limits for the quality characteristics are listed in the
contract for the work in question.
(b) Acceptance. The work in the lot will be paid for at a final pay factor when all inspections or test
results are completed and evaluated.
Before determining the final pay factor, the work may be incorporated into the project provided the
current pay factor does not fall below 0.90. If a lot is concluded with fewer than 3 samples, the
material will be evaluated under Subsection 106.04.
If the current pay factor of a lot falls below 0.90, end production. Production may resume after the
Contractor takes effective and acceptable actions to improve the quality of the production.
A lot containing an unsatisfactory percentage of non-specification material (less than 1.00 pay factor)
is accepted provided the lowest single pay factor has not fallen into the reject portion of Table 106-2.
A lot containing an unsatisfactory percentage of non-specification material with the lowest single pay
factor falling into the reject portion of Table 106-2 is rejected. Remove rejected material from the
work.
28
Section 106
When approved, it is permissible to voluntarily remove non-specification material and replace it with
new material to avoid or minimize a pay factor of less than 1.00. New material will be sampled, tested,
and evaluated according to this Subsection.
Any quantity of material may be rejected based on visual inspection or test results. Do not incorporate
rejected material in the work. The results of tests run on rejected material will be excluded from the lot.
(c) Statistical evaluation. The Variability-Unknown/Standard Deviation Method will be used to
determine the estimated percentage of the lot that is within specification limits.
The estimated percentage of work that is within the specification limits for each quality characteristic
will be determined as follows:
n
where: ∑ = summation of:
x = individual test value
n = total number of test values
(2) Calculate the standard deviations:
2
n
(
x
)
(
x
)2
s =
n
(
n
1)
where: ∑(x2) = summation of the squares of individual test values
(∑x)2 = summation of the individual test values squared
-
(3) Calculate the upper quality index (QU): QU = US
s
where: USL = upper specification limit
Note: The USL is equal to the contract specification limit or the target value plus the allowable
deviation.
(4) Calculate the lower quality index (QL): QL = xLSL
s
where: LSL = lower specification limit
Note: The LSL is equal to the contract specification limit or the target value minus the allowable
deviation.
(5) From Table 106-1, determine PU (the estimated percentage of work within the USL).
PU corresponds to a given QU. If a USL is not specified, PU is 100.
(6) From Table 106-1, determine PL (the estimated percentage of work within the lot within the
LSL). PL corresponds to a given QL. If an LSL is not specified, PL is 100.
(7) Calculate the total estimated percentage of work within the USL and LSL:
PU + PL - 100
(8) Repeat steps 1 through 7 for each quality characteristic listed for statistical evaluation.

33
Section 106
(d) Pay factor determination (value of the work). The pay factor for a lot will be determined as
follows:
(1) The pay factor for each quality characteristic will be determined from Table 106-2 using the
total number of test values and the total estimated percentage within the specification limits from
Subsection 106.05(c)(7).
(2) When all quality characteristics for a lot are Category I, the lot pay factor is based on the
lowest single pay factor for any Category I quality characteristic. The maximum obtainable pay
factor is 1.05.
(3) When quality characteristics for a lot are both Category I and II, the lot pay factor is based on
the following:
(a) When all Category II quality characteristics are 1.00, the lot payment is based on the
lowest single pay factor for all Category I characteristics. The maximum obtainable pay
factor is 1.05.
(b) When any Category II quality characteristic is less than 1.00, the lot payment is based on
the lowest single pay factor for any Category I or II quality characteristic.
(4) When all quality characteristics for a lot are Category II, the lot pay factor is based on the
lowest single pay factor for any Category II quality characteristic. The maximum obtainable pay
factor is 1.00.
(5) Adjusted payment for material in a lot will be made at a price determined by multiplying the
contract unit bid price by the lot pay factor as determined above, or as described in the Payment
Subsection of the Section ordering the work.
106.06 Inspection at the Plant. Work may be inspected at the point of production or fabrication.
Manufacturing plants may be inspected for compliance with specified manufacturing methods. Material
samples may be obtained for laboratory testing for compliance with quality requirements. Allow full entry
at all times to the parts of the plant producing the work.
106.07 Partial and Final Acceptance. Maintain the work during construction and until the project is
accepted. Repair damage caused by the Contractor before final acceptance of the entire project at no cost
to the Government. See FAR Clause 52.236-11 Use and Possession Prior to Completion.
(a) Partial acceptance. When a segment of the project is completed, a final inspection of that segment
may be requested. If the segment is complete and in compliance, it may be accepted. If accepted, the
CO may relieve the Contractor of further responsibility for maintaining accepted work.
When public traffic is accommodated through construction and begins using sections of roadway as
they are completed, continue maintenance of such sections until final acceptance.
34
Section 106
(b) Final acceptance. Notify the CO when the entire project is complete to schedule an inspection. If
work is determined to be complete, the inspection will constitute the final inspection. The Contractor
will be notified in writing of final acceptance as of the date of the final inspection. Final acceptance
relieves the Contractor of further responsibility for the maintenance of the project.
If the inspection discloses unsatisfactory work, the CO will provide to the Contractor a list of the work
that is incomplete or requires correction. Immediately complete or correct the work. Submit notification
when the work has been completed as provided above.
35

the CO and continue operations in other areas. The CO will inform the Contractor when operations may
resume at the discovery site.
When utilities are to be relocated or adjusted, the Government will notify utility owners affected by the
relocations or adjustments.
Before beginning work in an area, contact the local utility locating service to mark the utilities. Protect
utilities from construction operations. Cooperate with utility owners to expedite the relocation or
adjustment of their utilities to minimize interruption of service and duplication of work.
If utility services are interrupted as a result of damage by the construction, immediately notify the utility
owner, the CO, and other proper authorities. Cooperate with them until service is restored. Do not work
around fire hydrants until provisions for continued service are made and approved by the local fire

Section 108. — PROSECUTION AND PROGRESS
108.01 Commencement, Prosecution, and Completion of Work. Follow the requirements of FAR
Clause 52.211-10 Commencement, Prosecution, and Completion of Work.
A preconstruction conference will be held after the contract is awarded and before beginning work. Seven
days before the preconstruction conference, submit copies of the preliminary construction schedule
according to Section 155.
108.02 Subcontracting. Follow the requirements of FAR Clause
52.219-14 Limitations on
Subcontracting, FAR Clause
52.222-11 Subcontracts
(Labor Standards), and FAR Clause
52.236-1 Performance of Work by the Contractor.
Subcontracting does not relieve the Contractor of liability and responsibility under the contract and does
not create any contractual relation between subcontractors and the Government. The Contractor is liable
and responsible for actions or lack of action of subcontractors.
Within 14 days of subcontract award, submit an SF 1413, Statement and Acknowledgment with Part I
completed. Complete other forms that may be provided by the Government to show the work
subcontracted and the total dollar amount of the subcontract. For subcontracts involving on-site labor,
require the subcontractor to complete Part II of the SF 1413 and complete other forms that may be
provided by the Government. Submit a separate statement documenting the cumulative amount of on-site
subcontracts to date as a percentage of the original contract amount. Submit this information on
subcontracts at lower tiers.
In FAR Clause 52.219-8, Utilization of Small Business Concerns and FAR Clause 52.232-27 Prompt
Payment for Construction Contracts, the term "subcontracts" includes on-site and off-site work and supply
contracts.
For contracts in which FAR Clause 52.219-14 Limitations on Subcontracting applies, the percentage of
work performed by the Contractor will be computed as the cost of the contract work performed by the
Contractor’s employees, not including the cost of material, divided by the cost of all contract work, not
including the cost of material. For contracts on which FAR Clause 52.236-1 Performance of Work applies,
the percentage of work performed by the Contractor will be computed as the cost of the contract work
performed on-site by the Contractor’s employees divided by the total cost of the contract.
108.03 Determination and Extension of Contract Time. Follow the requirements of FAR Clause
52.211-10 Commencement, Prosecution, and Completion of Work.
(a) Definitions.
(1) Time Impact Analysis. The procedure by which the Contractor demonstrates the effect of
specific time impacts on the overall construction schedule. Time impacts may result in an
increase or decrease in contract time.
(2) Float. The amount of time between when an activity "can start" (the early start) and when an
activity "must start" (the late start).
(b) Time Impact Analysis. Comply with the applicable contract clauses when requesting a time
extension. Notify the CO in writing within 7 days after identifying a time impact.
41
Section 108
Submit a time impact analysis and revised construction schedule within 14 days after the end of the
time impact event for which notice has been given. Include the following:
(1) A title page or header block with:
(a) Contract number;

(d) Other Government caused delay.
(3) A copy of the most current approved schedule existing before the impact.
(4) A detailed narrative describing each impact event. Describe impacts to each affected activity
in the construction schedule. Include the following:
(a) Contract clauses under which the request is being made;
(b) Cause of the impact;
(c) Start date of the impact;
(d) Duration of the impact; and
(e) Methods to be employed to re-sequence or reschedule the work to mitigate the impact.
Discuss the feasibility of re-sequencing future work to mitigate delay. Re-sequencing or
rescheduling of work will be at no cost to the Government. Include corresponding rationale
and assumptions of measures which increase the cost of mitigating the impact.
(5) A revised construction schedule to show the impact of the activities identified, including
re-sequencing which would mitigate the delay.
(c) Time extensions. Only delays or modifications that affect critical activities or cause noncritical
activities to become critical will be considered for time extensions.
When a Critical Path Method schedule is used, no time extension will be made for delays or
modifications that use available float as shown in the most current approved schedule existing before
the impact.
No time extension will be made for a claim that states insufficient time was provided in the contract.
(d) Execution of the Time Impact Analysis. Incorporate accepted logic changes or time extensions
into the baseline schedule by the next monthly submittal.

Section 109. — MEASUREMENT AND PAYMENT
109.01 Measurement of Work. Take and record measurements and perform calculations to determine
pay quantities for invoicing for work performed. Take or convert measurements of work according to
U.S. Customary (Metric) measure.
Unless otherwise specified, measure when the work is in-place and complete according to the contract.
Measure the actual work performed, except do not measure work outside the design limits or other
adjusted or specified limits (staked limits). Measure structures to the lines according to the plans or to
approved lines adjusted to fit field conditions.
Take measurements as described in Subsection 109.02 unless otherwise modified by the Measurement
Subsection of the Section controlling the work being performed. Measurement of quantities for payment
for the individual pay items will be based on the contract price for each pay item according to Table
109-1.
Table 109-1
Decimal Accuracy of Quantities for Payment
Decimal Accuracy
Contract Price
of Quantities
for Payment
< $1.00
0 decimal
≥ $1.00 to < $100.00
1 decimal
≥ $100.00 to < $1000.00
2 decimals
≥ $1000.00
3 decimals
Decimal precision for measurement is one decimal beyond accuracy of quantities for payment.
Remeasure quantities if it has been determined that a portion of the work is acceptable, but has not been
completed to the lines, grades, and dimensions shown in the plans or established by the CO.
Submit measurement notes within 24 hours of completing work that is in-place and complete according to
the contract. For on-going work, submit measurement notes daily. When work is not complete, identify the
measurement as being an interim measurement. Submit the final measurement when the installation is
completed. Measurement notes form the basis of the Government’s receiving report; see Subsection
109.08(d). For lump sum pay items, submit documentation to support invoiced progress payment on a
monthly basis.
Use an acceptable format for measurement records. As a minimum, include the following information:
(a) Project number and name;
(b) Pay item number and description;
(c) Date the work was performed;
(d) Location of the work;
(e) Measured quantity;

defined as follows:
(a) Acre (Hectare). 43,560 square feet (10,000 square meters). Make longitudinal and transverse
measurements for area computations horizontally. Do not make deductions from the area computation
for individual fixtures having an area of 500 square feet (50 square meters) or less.
(b) Contract quantity. The quantity to be paid is the quantity listed in the bid schedule. The contract
quantity will be adjusted for authorized changes that affect the quantity or for errors made in
computing this quantity. If there is evidence that a quantity specified as a contract quantity is incorrect,
submit calculations, drawings, or other evidence indicating why the quantity is in error and request in
writing that the quantity be adjusted.
(c) Cubic yard (Cubic meter).
(1) Cubic yard (Cubic meter) in-place. Measure solid volumes by a method approved by the
CO or by the average end area method as follows:
(a) Take cross-sections of the original ground and use design or staked templates to
determine end areas. Do not measure work outside of the lines or slopes established by the
CO;
(b) If a portion of the work is acceptable, but is not completed to the established lines and
slopes; retake cross-sections or comparable measurements of that portion of the work. Use
the remeasurements to calculate new end areas; and
(c) Compute the quantity using the average end areas multiplied by the horizontal distance
along a centerline or reference line between the end areas. Deduct quantities outside the
designed or staked limits.
(2) Cubic yard (Cubic meter) in the hauling vehicle. Measure the cubic yard (cubic meter)
volume in the hauling vehicle using three-dimensional measurements at the point of delivery.
Use vehicles bearing a legible identification mark with the body shaped so the actual contents
may be readily and accurately determined. Before use, mutually agree in writing on the volume
of material to be hauled by each vehicle. Vehicles carrying less than the agreed volume may be
rejected or accepted at the reduced volume.
46
Section 109
Level selected loads. If leveling reveals the vehicle was hauling less than the approved volume,
reduce the quantity of all material received since the last leveled load by the same ratio as the
current leveled load volume is to the agreed volume. Payment will not be made for material in
excess of the agreed volume.
Material measured in the hauling vehicle may be weighed and converted to cubic yards (cubic
meters) for payment purposes if the conversion factors are mutually agreed to in writing.
(3) Cubic yard (Cubic meter) in the structure. Measure according to the lines of the structure
as shown in the plans, except as altered by the CO to fit field conditions. Make no deduction for
the volume occupied by reinforcing steel, anchors, weep holes, piling, or pipes less than 8 inches
(200 millimeters) in diameter.
(4) Cubic yard (Cubic meter) by metering. Use an approved metering system.
(d) Day. A calendar day beginning and ending at midnight. Round portions of a day up to the full day.

the volume to 60 °F (15 °C) using recognized standard correction factors.
(g) Hour. 60 minutes. Measure the actual number of hours ordered by the CO and performed by the
Contractor. Round portions of an hour up to the next half hour. Measure time in excess of 40 hours per
week at the same rate as the first 40 hours.
(h) Linear foot (Meter). As applicable, measure the work along its length from end-to-end; parallel to
the base or foundation; along the top; along the front face; or along the invert. Do not measure
overlaps.
(i) Lump sum. Do not measure directly. The bid amount is complete payment for all work described
in the contract and necessary to complete the work for that pay item. The quantity is designated as
"All". Estimated quantities of lump sum work shown in the contract are approximate.
(j) M-gallon. 1,000 gallons. Measure according to Subsection 109.02(f).
(k) Mile (Kilometer). 5,280 linear feet (1000 meters). Measure horizontally along the centerline of

109.03.
No adjustment in a contract price will be made for variations in quantity due to differences in the
specific gravity or moisture content.
Use net-certified scale masses or masses based on certified volumes in the case of rail shipments as a
basis of measurement subject to correction when asphalt material is lost from the car or the distributor,
wasted, or otherwise not incorporated in the work. When asphalt material is shipped by truck or
transport, net-certified masses, subject to correction for loss or foaming, may be used for computing
quantities.
When emulsified asphalt is converted from volume to mass, use a factor of 240 gallons per ton
(1000 liters per metric ton) regardless of temperature.
When asphalt binder for asphalt concrete pavement is stored in tanks devoted exclusively to the
project, base quantities on invoices. When asphalt binder for asphalt concrete pavement is not stored in
tanks devoted exclusively to the project or when the validity of the quantity requested for payment is in
question; base quantities on the asphalt content determined by testing.
(r) Week. A 7 day period beginning and ending at the same designated time. Measure portions of a
week by prorating based on the total days worked.
109.03 Weighing Procedures and Devices. Batch masses may be acceptable for determination of pay
quantities when an approved automatic weighing, cycling, and monitoring system is included as part of the
batching equipment.
When a weighing device is determined to indicate less than true mass; no additional payment will be made
for material previously weighed and recorded. When a weighing device is determined to indicate more
than true mass; material received after the last previously correct weighing accuracy test will be reduced
by the percentage of error in excess of 0.5 percent.
When material is proportioned or measured and paid for by mass, provide one of the following:
(a) Commercial weighing system. Use permanently-installed and certified commercial scales.
48
Section 109
(b) Invoices. If bulk material is shipped by truck or rail and is not passed through a mixing plant,
submit a supplier's invoice with net mass or volume converted to mass. Periodic check weighing may
be required.
(c) Project weighing system. Furnish, erect, and maintain acceptable automatic digital scales. Provide
scales that record mass at least to the nearest 100 pounds (50 kilograms). Maintain the scale accuracy
to within 0.5 percent of the correct mass throughout the range of use.

109.05 Scope of Payment. Payment for contract work is provided, either directly or indirectly, under the
pay items listed in the bid schedule.
(a) Direct payment. Payment is provided directly under a pay item listed in the bid schedule when one
of the following applies:
(1) The work is measured in the Measurement Subsection of the Section ordering the work and
the bid schedule contains a pay item for the work from the Section ordering the work.
(2) The Measurement Subsection of the Section ordering the work, references another Section
for measuring the work and the bid schedule contains a pay item for the work from the
referenced Section.
(b) Indirect payment. Work for which direct payment is not provided is a subsidiary obligation of the
Contractor. Payment for such work is indirectly included under other pay items listed in the bid
schedule. This includes instances when the Section ordering the work references another Section for
performing the work and the work is not referenced in the Measurement Subsection of the Section
ordering the work.
Compensation provided by the pay items included in the bid schedule is full payment for performing
contract work in a complete and acceptable manner. Risk, loss, damage, or expense arising out of the
nature or prosecution of the work is included in the compensation provided by the pay items.
50
Section 109
Work measured and paid for under one pay item will not be paid for under other pay items.
The quantities listed in the bid schedule are approximate unless designated as a contract quantity. Limit
pay quantities to the quantities staked, ordered, or otherwise authorized before performing the work.
Payment will be made for the actual quantities of work performed and accepted or material furnished
according to the contract. No payment will be made for work performed in excess of that staked, ordered,
or otherwise authorized.
109.06 Pricing of Adjustments. Determine costs according to FAR Part 31 Contract Cost Principles
and Procedures. Follow the requirements of FAR clauses providing for an equitable price adjustment.
If agreement on price and time cannot be reached, the CO may make a unilateral determination.

defective and the Contractor will be notified according to FAR Clause
52.232-27(a)(2).
Defective invoices will be returned to the Contractor within
7 days after receipt by the
Government’s designated billing office. Correct and resubmit returned invoices. If the defects are
minor, the Contractor may elect, in writing, to accept the quantities and contract prices shown on
the Government’s receiving report for payment.
(f) Partial payments. Progress payments may include partial payment for material to be
incorporated in the work according to FAR Clause 52.232-5(b)(2), provided the material meets the
requirements of the contract and is delivered on, or in the vicinity of, the project site or stored in
acceptable storage places.
Partial payment for material does not constitute acceptance of the material for use in completing
items of work. Partial payments will not be made for living or perishable material until incorporated
into the project.
Individual and cumulative partial payments for preparatory work and material will not exceed the
lesser of:
(1) 80 percent of the contract price for the pay item; or
(2) 100 percent of amount supported by copies of invoices submitted.
The quantity paid will not exceed the corresponding quantity estimated in the contract. The CO may
adjust partial payments as necessary to protect the Government.
(g) Retainage. Follow the requirements of FAR Clause 52.232-5 Payments under Fixed Price
Construction Contracts.

work. The CO may order the GPS localization calibration and associated 3D model to be broken into
two or more zones to maintain the localized relationship between control points and original ground.
(b) Centerline establishment. Establish or reestablish centerline at roadway design cross-section
locations and as necessary to construct the work. Reestablish the centerline when construction
survey and staking work does not meet the tolerances.
(c) Original ground topographic verification. Use an approved method to regenerate cross-section
data in areas where theoretical and actual ground elevations do not meet a tolerance of plus or minus
0.5 feet (150 millimeters). Retake cross-section to verify existing ground topography to mapping.
Submit cross-section or 3D data in electronic and printed format for approval. Reduce cross-sections
to horizontal and vertical distances from centerline.
Retake cross-section 10 feet (3 meters) beyond catch points to verify existing ground topography.
(d) Slope and references stakes. Perform the following:
(1) AMG method. After clearing operations are completed, set centerline reference stakes and
hubs on both sides of centerline at 100-foot (30-meter) intervals at the clearing limit locations.
Where clearing limits are greater than
10 feet
(3 meters) vertically,
25 feet
(8 meters)
horizontally, or both from subgrade hinge point; provide an additional reference stake and hub as
approved by the CO. Label each centerline reference stake with station, hub elevation, and offset
from centerline.
Construct a 1000-foot (300-meter) long test section using AMG on the project at an approved
location before beginning grading operations. Select a test location with superelevation and
curve widening transitions if applicable. Notify the CO 10 days before beginning the test section.
Demonstrate capability, knowledge, equipment, and experience to achieve work within
tolerances. Allow 14 days to evaluate the test section. Do not start full grading operations until
the test section is approved.
Provide as-built cross-sections at random locations specified by the CO not to exceed 500-foot
(150-meter) intervals. If as-built cross-sections do not meet the tolerances in Subsection
204.13(d); rework the section until the specified tolerances are achieved and provide additional
cross-sections as directed by the CO at no cost to the Government.
61
Section 152
(2) Conventional survey methods. Verify and set slope stakes on both sides of centerline at the
theoretical catch point. If the theoretical catch point is not within a tolerance of
0.5 feet
(150 millimeters), perform original ground topographic verification according to Subsection
152.05(c). Set the slope stake at the actual intersection of the design roadway slope with the
natural ground-line. Set reference stakes outside the clearing limits. Include reference points and
slope-stake information on the reference stakes.
Establish slope stakes in the field as the actual point of intersection of the design roadway slope
with the natural ground-line when theoretical catch point information is not available.
(e) Clearing and grubbing limits. Set clearing and grubbing limits on both sides of centerline based
on the actual slope-stake locations.
(f) Grade-finishing stakes.
(1) AMG method. Construct a 1000-foot (300-meter) long test section using AMG on the
project at an approved location before beginning grading operations. Select a test location with
superelevation and curve widening transitions if applicable. Notify the CO 10 days before
beginning the test section. Demonstrate the capability, knowledge, equipment, and experience to
achieve work within tolerances. Allow 14 days to evaluate the test section. Do not start full
grading operations until the test section is approved.
Verify the grade elevation and horizontal alignment of roadway grade-finishing operations. Use
conventional survey methods at random locations specified by the CO, not to exceed 500-foot
(150-meter) intervals. Submit 3D coordinates of grade-finishing quality control checks.
(2) Conventional survey methods. Set grade-finishing stakes for grade elevations and
horizontal alignment, on centerline and on each shoulder at design roadway cross-section
locations. Set stakes at the top of subgrade and the top of each aggregate course. Reset grade
finishing stakes as many times as necessary to construct the subgrade and each aggregate course.
During turnout or pullout construction, set stakes on the centerline, on each normal shoulder, and
on the shoulder of the turnout. In parking areas, set stakes at the center and along the edges of the
parking area. Set stakes in ditches to be paved.
