SECTION 103
SCOPE OF WORK
103.1 INTENT OF CONTRACT. The intent of the contract is to provide for performance and
completion of the work described. The Contractor shall furnish all labor, materials, equipment, tools,
transportation and supplies required to complete the Work in accordance with the plans, project
specifications and terms of the contract. When an item in the contract contains a choice to be made by the
Contractor, the Contractor shall indicate the choice to the Engineer in writing. When the project
specifications reference or require the use of "manufacturer's recommendations or specifications," the
Contractor shall provide the Engineer with a current copy of these recommendations or specifications.
103.2 ALTERATION OF THE CONTRACT. Without invalidating the Contract, City may, at any
time or from time to time, order addition, deletion, or revision of Work by a Change Order or a Work
Change Directive. Upon receipt of any such document, Contractor shall promptly proceed with the Work
involved which will be performed under the applicable conditions of the Contract Documents (except as
otherwise specifically provided). Pay Items affected by such additions, deletions, or revisions shall be
performed in accordance with the requirements of the Contract Documents, and payment will be made at
the same unit prices as other parts of the Work, except as provided in Section 105.
When the City orders deletion of Work because of untimely or unsatisfactory performance by the
Contractor, the City may perform the Work and back charge the actual cost of performing the Work.
The Contractor shall cooperate with the City or its contractors during performance of the Work.
City may order addition, deletion, or revision of Work and authorize adjustments to the Contract Amount
and/or Contract Time in a formal Change Order. Engineer may order addition, deletion, or revision of
Work, but may not authorize adjustments to the Contract Amount or Contract Time, in a Work Change
Directive. A Work Change Directive is evidence that the parties expect that the change ordered or
documented by a Work Change Directive will be incorporated in a subsequent Change Order following
negotiations by the parties as to its effect, if any, on the Contract Amount or Contract Time.
Engineer may authorize minor variations in the Work from the requirements of the Contract Documents
which do not involve an adjustment in the Contract or the Contract Time and are compatible with the
design concept of the completed Project as a functioning whole as indicated by the Contract Documents.
Engineer may order changes in details, including changes in materials, processes, and sequences.
These minor variations and changes in details may be accomplished by a Field Order and will be binding on
City and also on Contractor, who shall perform the Work involved promptly. If City or Contractor believes
that a Field Order justifies an adjustment in the Contract Amount or Contract Time, or both, and the
parties are unable to agree on entitlement to or on the amount or extent, if any, of any such adjustment, a
Claim may be made therefor as provided in Section 105.
The requirements of the Contract Documents may be supplemented, and minor variations and deviations
in the Work may be authorized, by one or more of the following ways:
a. Field Order
b. Engineer's approval of a Shop Drawing or Sample (subject to provisions of Section 104)
c. Engineer's written interpretation or clarification
Alterations to the contract as provided for by this section shall not invalidate the contract nor release the
surety, and the Contractor agrees to accept the Work as altered, as if it had been part of the original
contract. The Contractor shall notify the surety of any alterations to the contract. Alterations of the
103 - 1

3/18/2020
contract shall not involve work beyond the termini of the proposed work except as necessary to
satisfactorily complete the project. Approval of all plan changes is subject to the approval and concurrence
from the appropriate funding source. No plan change will be assumed to be approved until the signed and
approved plan change is returned to the originator.
103.3 MAINTENANCE OF TRAFFIC. Contractor shall furnish, erect, and maintain traffic control
in accordance with the plans and MUTCD. This includes furnishing, erecting, and maintaining barricades,
warning signs and delineators, and providing flaggers, pilot cars and other traffic control. The Contractor
shall keep the portion of the project being used by public traffic, whether through or local traffic, in such
condition that traffic (including mail delivery) will be adequately accommodated. The Contractor shall also
provide and maintain in a safe condition all temporary approaches or crossings, intersections with roads,
streets, businesses, parking lots, residences, garages and farms. Traffic control will be paid for at the unit
price and lump sum items included in the contract. Payment will include all labor, materials, equipment,
supplies, and incidentals required to complete the work per Section 1306. If no pay items for traffic control
exist, costs for traffic control will be included in other unit and lump sum pay items.
103.4 FINAL CLEANING UP. Before final completion, the right-of-way, borrow and local material
sources, and areas occupied by the Contractor in connection with the work shall be cleaned of rubbish,
excess materials, temporary structures, haul roads and equipment. All parts of the work, including property
adjacent to the right-of-way, which have been damaged or rendered unsightly during the work shall be left
in satisfactory condition and when required, the right-of-way shall be mowed in accordance with City
maintenance standards, all at no direct pay.
103.5 GUARANTEES. The Contractor guarantees, by signing the contract, mechanical and electrical
equipment, apparatus, materials and workmanship provided under the contract for a period of two years
after substantial completion on projects not involving federal funds and six months after final completion on
28 Federal-Aid Projects. Instruction sheets that are required to be furnished by the manufacturer for
materials, supplies, and operation shall be delivered by the Contractor to the Engineer prior to final
completion of the project, with the following written warranties and guarantees:
1. The manufacturer's standard warranty for each piece of mechanical and electrical equipment
or apparatus furnished under the contract.
2. The Contractor's guarantee that, during the guarantee period, necessary repair or
replacement of the warranted equipment or apparatus will be made by the Contractor at
no direct pay.
3. The Contractor's guarantee for satisfactory operation of the mechanical and electrical
systems furnished and constructed under the contract for the guarantee period.
4. The Contractor's guarantee per Specification Section 4700.
103.6 DIFFERING SITE CONDITIONS, SUSPENSIONS OF WORK, AND SIGNIFICANT
CHANGES IN THE CHARACTER OF THE WORK.
A. Differing Site Conditions:
1. During the progress of the work, if subsurface or latent physical conditions are
encountered at the site differing materially from those indicated in the contract or if
unknown physical conditions of an unusual nature, differing materially from those
ordinarily encountered and generally recognized as inherent in the work provided for
in the contract, are encountered at the site, the party discovering such conditions shall
promptly notify the other party in writing of the specific differing conditions before they
are disturbed and before the affected work is performed.
103 - 2

3/18/2020
2. Upon written notification, the Engineer will investigate the conditions and if he
determines that the conditions materially differ and cause an increase or decrease in
the cost or time required for the performance of any work under the contract, an
adjustment, excluding loss of anticipated profits, will be made and the contract modified
in writing accordingly. The Engineer will notify the Contractor of his determination
whether or not an adjustment of the contract is warranted.
3. No contract adjustment which results in a benefit to the Contractor will be allowed
unless the Contractor has provided the required written notice.
4. The presence of ground water does not constitute differing site conditions. The
Contractor should expect to encounter ground water during normal excavation
operations.
B. Suspensions of Work Ordered by the Engineer.
1. If the performance of all or any portion of the work is suspended or delayed by the
Engineer in writing for an unreasonable period of time (not originally anticipated,
customary or inherent to the construction industry) and the Contractor believes that
additional compensation and/or contract time is due as a result of such suspension or
delay, the Contractor shall submit to the Engineer in writing a request for adjustment
within 7 calendar days of receipt of the notice to resume work. The request shall set
forth the reasons and support for such adjustment.
2. Upon receipt, the Engineer will evaluate the Contractor's request. If the Engineer agrees
that the cost and/or time required for the performance of the contract has increased
as a result of such suspension and the suspension was caused by conditions beyond the
control of and not the fault of the Contractor, its suppliers, or subcontractors, and not
caused by weather, the Engineer will make an adjustment (excluding profit) and modify
the contract in writing accordingly. The Engineer will notify the Contractor of his
determination whether or not an adjustment of the contract is warranted.
3. No contract adjustment will be allowed unless the Contractor has submitted the
request for adjustment within the time prescribed.
4. No contract adjustment will be allowed under this clause to the extent that
performance would have been suspended or delayed by any other cause, or for which
an adjustment is provided for or excluded under any other term or condition of this
contract.
C. Significant Changes in the Character of Work.
1. The Engineer reserves the right to make, in writing, at any time during the work, such
changes in quantities and such alterations in the work as are necessary to satisfactorily
complete the project. Such changes in quantities and alterations shall not invalidatethe
contract nor release the surety, and the Contractor agrees to perform the work as
altered.
2. If the alterations or changes in quantities significantly change the character of the work
under the contract, whether or not changed by any such different quantities or
alterations, an adjustment, excluding loss of anticipated profits, will be made to the
contract. The basis for the adjustment shall be agreed upon prior to the performance
of the work. If a basis cannot be agreed upon, then an adjustment will be made either
for or against the Contractor in such amount as the Engineer may determine to be fair
and equitable.
103 - 3

3/18/2020
3. If the alterations or changes in quantities do not significantly change the character of
the work to be performed under the contract, the altered work will be paid for as
provided elsewhere in the contract.
4. The term "significant change" shall be construed to apply only to the following
circumstances:
a. When the character of the work as altered differs materially in kind or nature from
that involved or included in the original proposed construction or;
b. When a major item of work, as defined elsewhere in the contract, is increased, or
decreased, in excess of 25 percent of the contract quantity as awarded. Any
adjustment in unit price will be made on only that portion of the major item
exceeding the 25 percent increase, or, in the case of a decrease of the item by 25
percent or more, the remaining portion will be adjusted.
c. Where conflicts exist between these requirements and other sections of the
specifications, these requirements will govern.
103.7 REPORTS. The following reports of explorations and tests of subsurface conditions at or
adjacent to the site are available to the contractor for review.
a. Boring Logs completed by Dave Rambaran Geosciences, LLC for both Curtis Lane and Lakeshore
Drive and are included in the plan set on pages C4.9 - C4.10.
b. As-Built drawings for Lakeshore Drive are included in the plan set and can be found on page C4.8.
Contractor may utilize the technical data contained in boring logs, recorded measurements of subsurface
water levels, laboratory test results, and other factual, objective information regarding conditions at the Site
that are set forth in any geotechnical or environmental report prepared for the Project and made available
to Contractor, but such reports are not Contract Documents. , Contractor may not make any claim against
the City or the Engineer with respect to:
a. The completeness of such reports for the Contractor's purposes, including, but
not limited to, any aspects of the means, methods, techniques, sequences, and
procedures of construction to be employed by the Contractor, and safety
precautions and programs incident thereto; or
b. Other data, interpretations, opinions, and information contained in such reports;
or
c. Any Contractor interpretation of or conclusion drawn from any technical data or
any such other data, interpretations, opinions, or information.
