A. Intent of Certain Terms or Adjectives

1. Whenever in the Contract Documents the terms “as allows,” “as approved,” or terms of like effect or import are
used, or the adjectives “reasonable,” “suitable,” “acceptable,” “proper,” “satisfactory,” or adjectives of like effect
or import are used to describe an action or determination of ENGINEER as to the Work, it is intended that such
action or determination will be solely to evaluate, in general, the completed Work for compliance with the
requirements of and information in the Contract Documents and conformance with the design concept of the
completed Project as a functioning whole as shown or indicated in the Contract Documents (unless there is a
specific statement indicating otherwise). The use of any such term or adjective shall not be effective to assign to
ENGINEER any duty or authority to supervise or direct the performance of the Work or any duty or authority to
undertake responsibility contrary to the provisions of paragraph 9.10 or any other provision of the Contract
Documents.

B. Day

1. The work “day” shall constitute a calendar day of regular working hours except Saturdays, Sundays and any
legal holiday.

C. Defective

1. The word “defective,” when modifying the work “Work,” refers to Work that is unsatisfactory, faulty, or
deficient in that it does not conform to the Contract Documents or does not meet the requirements of any
inspection, reference standard, test, or approval referred to in the Contract Documents, or has been damaged prior
to ENGINEER’s recommendation of final payment (unless responsibility for the protection thereof has been
assumed by OWNER at Substantial Completion in accordance with paragraph 14.04 or 14.05).

D. Furnish, Install, Perform, Provide
1. The word “furnish,” when used in connection with services, materials, or equipment, shall mean to supply and

deliver said services, materials, or equipment to the Site (or some other specified location) ready for use or
installation and in usable or operable condition.

GC - 7 of 53

2. The word “install,” when used in connection with services, materials, or equipment, shall mean to furnish and
install said services, materials, or equipment complete and ready for intended use.

3. The words “perform” or ‘Provide,” when used in connection with services, materials, or equipment, shall mean
to furnish and install said services, materials, or equipment complete and ready for intended use.

4. When “furnish,” “install,” “perform,” or “provide” is not used in connection with services, materials, or
equipment in a context clearly requiring an obligation of CONTRACTOR, “provide” is implied.

E. Unless stated otherwise in the Contract Documents, words or phrases which have a well-known technical or
construction industry or trade meaning are used in the Contract Documents in accordance with such recognized
meaning.

CONTRACTOR shall have an additional ten days to make corrections and adjustments and to complete and resubmit
the schedules. No progress payment shall be made to CONTRACTOR until acceptable schedules are submitted to
ENGINEER.

1. The progress schedule will be acceptable to ENGINEER if it provides an orderly progression of the Work to
completion within any specified Milestones and the Contract Times. Such acceptance will not impose on
ENGINEER responsibility for the progress schedule, for sequencing, scheduling, or progress of the Work nor
interfere with or relieve CONTRACTOR from CONTRACTOR’s full responsibility therefore.

2. CONTRACTOR’s schedule of Shop Drawing and Sample submittals will be acceptable to ENGINEER if it
provides a workable arrangement for reviewing and processing the required submittals.

3. CONTRACTOR’s schedule of values will be acceptable to ENGINEER as to form and substance if it provides a
reasonable allocation of the Contract Price to component parts of the Work.

Date of the Agreement if there were no Bids), except as may be otherwise specifically stated in the Contract
Documents.

2. No provision of any such standard, specification, manual or code, or any instruction of a Supplier shall be
effective to change the duties or responsibilities of OWNER, CONTRACTOR, or ENGINEER, or any of their
subcontractors, consultants, agents, or employees from those set forth in the Contract Documents, nor shall any
such provision or instruction be effective to assign to OWNER, ENGINEER, or any of ENGINEER’s Consultants,
agents, or employees any duty or authority to supervise or direct the performance of the Work or any duty or
authority to undertake responsibility inconsistent with the provisions of the Contract Document.

3.03 Reporting and Resolving Discrepancies
A. Reporting Discrepancies

1. If, during the performance of the Work, CONTRACTOR discovers any conflict, error, ambiguity, or
discrepancy within the Contract Documents or between the Contract Documents and any provision of any Law or
Regulation applicable to the performance of the Work or of any standard, specification, manual or code, or of any
instruction of any Supplier, CONTRACTOR shall report it to ENGINEER in writing at once. CONTRACTOR

ENGINEER or ENGINEER’s Consultant, including electronic media editions. This prohibition will survive final
payment, completion, and acceptance of the Work, or termination or completion of the Contract. Nothing herein shall
preclude CONTRACTOR from retaining copies of the Contract Documents for record purposes.

ARTICLE 4 - AVAILABILITY OF LANDS; SUBSURFACE AND PHYSICAL CONDITIONS; REFERENCE
POINTS

4.01 Availability of Lands

A. OWNER shall furnish the Site. OWNER shall notify CONTRACTOR of any encumbrances or restrictions not of
general application but specifically related to use of the Site with which CONTRACTOR must comply in performing
the Work. OWNER will obtain in a timely manner and pay for easements for permanent structures or permanent
changes in existing facilities. If CONTRACTOR and OWNER are unable to agree on entitlement to or on the amount
or extent, if any, of any adjustment in the Contract Price or Contract Times, or both, as a result of any delay in
OWNER’s furnishing the Site, CONTRACTOR may make a Claim therefore as provided in paragraph 10.05.

B. Upon reasonable written request, OWNER shall furnish CONTRACTOR with a current statement of record legal
title and legal description of the lands upon which the Work is to be performed and OWNER’s interest therein as
necessary for giving notice of or filing a mechanic’s or construction lien against such lands in accordance with
applicable Laws and Regulations.

C. CONTRACTOR shall provide for all additional lands and access thereto that may be required for temporary
construction facilities or storage of materials and equipment.

protection or disposition of such property. CONTRACTOR shall furnish the ENGINEER with copies of such
notifications and with copies of any agreements between the CONTRACTOR and the property OWNER’s concerning
such protection or disposition.

E. CONTRACTOR shall take all necessary precautions for the protection of corporate or private property, such as
walls and foundations of buildings, vaults, underground structures of public utilities, underground drainage facilities,
overhead structures of public utilities, trees, shrubbery, crops, and fences contiguous to the Work, of which the
Contract does not provide for removal. CONTRACTOR shall protect and carefully preserve all official survey
monuments, property marks, section markers, and Geological Survey Monuments, or other similar monuments, until
OWNER, or authorized Surveyor or agent has witnessed or otherwise referenced their location or relocation.
CONTRACTOR shall notify the ENGINEER of the presence of any such survey or property monuments as soon as
they are discovered.

F. CONTRACTOR shall be responsible for the damage or destruction of property of any character resulting from
neglect, misconduct, or omission in its manner or method of execution or the non-execution of the work, or caused by
defective work or the use of unsatisfactory materials, and such responsibility shall not be released until the work shall
have been completed and accepted and the requirements of the Construction Specifications complied with.

G. Whenever public or private property is so damaged or destroyed, the CONTRACTOR shall at its own expense,
restore such property to a condition equal to that existing before such damage or injury was done by repairing,
rebuilding, or replacing it as may be directed, or the CONTRACTOR shall otherwise make good such damage or

necessary, and the cost thereof shall be deducted from any compensation due, or which may become due, the
CONTRACTOR under its Contract.

4.02 Subsurface and Physical Conditions
A. Reports and Drawings:

1. Those reports of explorations and tests of subsurface conditions at or contiguous to the Site that ENGINEER has
used in preparing the Contract Documents; and

2. Those drawings of physical conditions in or relating to existing surface or subsurface structures at or contiguous
to the Site (except Underground Facilities) that ENGINEER has used in preparing the Contract Documents.

B. Limited Reliance by CONTRACTOR on Technical Data Authorized:

CONTRACTOR may rely upon the general accuracy of the “technical data” contained in such reports and drawings,
but such reports and drawings are not Contract Documents. Such “technical data” is identified in the Supplementary
Conditions. Except for such reliance on such “technical data,” CONTRACTOR may not rely upon or make any Claim
against OWNER, ENGINEER, or any of ENGINEER’s Consultants with respect to:

1. The completeness of such reports and drawings for CONTRACTOR’s purposes, including, but not limited to,
any aspects of the means, methods, techniques, sequences, and procedures of construction to be employed by
CONTRACTOR, and safety precautions and programs incident thereto; or

2. Other data, interpretations, opinions, and information contained in such reports or shown or indicated in such
drawings; or

3. Any CONTRACTOR interpretation of or conclusion drawn from any “technical data” or any such other data,
interpretations, opinions, or information.

C. Potential for Hazardous Materials:

Work may include excavation through, and removal of, soils potentially containing undocumented asbestos-containing
or other hazardous materials. Should the CONTRACTOR, while performing work under this Contract, uncover
hazardous materials, as defined in federal, state and local regulations, he/she shall immediately notify the Engineer.
No further disturbance of the area shall occur until the Engineer has collected and analyzed a representative sample of

the suspected material. The area shall be cordoned off and covered with 6-mil polyethylene sheeting and await further
directions from the Engineer.

4.03 Differing Subsurface or Physical Conditions

A. Notice: If CONTRACTOR believes that any subsurface or physical conditions at or contiguous to the Site that is
uncovered or revealed either:

1. Is of such a nature as to establish that any “technical data” on which CONTRACTOR is entitled to rely as
provided in paragraph 4.02 is materially inaccurate; or

2. Is of such a nature as to require a change in the Contract Documents; or
3. Differs materially from that shown or indicated in the Contract Documents; or
4. Is of an unusual nature, and differs materially from conditions ordinarily encountered and generally recognized

as inherent in work of the character provided for in the Contract Documents; then CONTRACTOR shall, promptly
after becoming aware thereof and before further disturbing the subsurface or physical conditions or performing any

GC - 12 of 53

Work in connection therewith (except in an emergency as required by paragraph 6.16.A), notify OWNER and
ENGINEER in writing about such condition. CONTRACTOR shall not further disturb such condition or perform
any Work in connection therewith (except as aforesaid) until receipt of written order to do so.

B. ENGINEER’s Review: After receipt of written notice as required by paragraph 4.03.4, ENGINEER will
promptly review the pertinent condition, determine the necessity of OWNER’s obtaining additional exploration or tests
with respect thereto, and advise OWNER in writing (with a copy to CONTRACTOR) of ENGINEER’S findings and
conclusions.

C. Possible Price and Times Adjustments

1. The Contract Price or the Contract Times, or both, will be equitably adjusted to the extent that the existence of
such differing subsurface or physical condition causes an increase or decrease in CONTRACTOR’ cost of, or
time required for, performance of the Work; subject, however, to the following:

a. Such condition must meet any one or more of the categories described in paragraph 4.03.A; and

b. With respect to Work that is paid for on a Unit Price Basis, any adjustment in Contract Price will be
subject to the provisions of paragraphs 9.08 and 11.03.

2.CONTRACTOR shall not be entitled to any adjustment in the Contract Price or Contract Times if:

a. CONTRACTOR knew of the existence of such conditions at the ttme CONTRACTOR made a final
commitment to OWNER in respect of Contract Price and Contract Times by the submission of a Bid or
becoming bound under a negotiated contract; or

b. The existence of such condition could reasonably have been discovered or revealed as a result of any
examination, investigation, exploration, test, or study of the Site and Contiguous areas required by the Bidding
Requirements or Contract Documents to be conducted by or for CONTRACTOR prior to CONTRACTOR’s
making such final commitment; or

c. CONTRACTOR failed to give the written notice within the time and as required by paragraph 4.03.A.

3. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amount or extent, if any, of any
adjustment in the Contract Price or Contract Times, or both, a Claim may be made therefore as provided in
paragraph 10.05. However, OWNER, ENGINEER, and ENGINEER’s Consultants shall not be liable to
CONTRACTOR for any claims, costs, losses, or damages (including but not limited to all fees and charges of
engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs)
sustained by CONTRACTOR on or in connection with any other project or anticipated project.

4.04 Underground Facilities

A. Shown or Indicated: The information and data shown or indicated in the Contract Documents with respect to
existing Underground Facilities at or contiguous to the Site is based on information and data furnished to OWNER or
ENGINEER by the OWNER’s of such Underground Facilities, including OWNER, or by others. Unless it is otherwise
expressly provided in the Supplementary Conditions:

1, OWNER and ENGINEER shall not be responsible for the accuracy or completeness of any such information or
data; and

2. The cost of all of the following will be included in the Contract Price, and CONTRACTOR shall have full
responsibility for:

a. Reviewing and checking all such information and data,

GC - 13 of 53

b. Locating all Underground Facilities shown or indicated in the Contract Documents.

c. Coordination of the Work with the OWNER’s of such Underground Facilities, including OWNER, during
construction, and

d. The safety and protection of all such Underground Facilities and repairing any damage thereto resulting
from the Work.

B. Not Shown or Indicated

1. If an Underground Facility is uncovered or revealed at or contiguous to the Site which was not shown or
indicated, or not shown or indicated with reasonable accuracy in the Contract Documents, CONTRACTOR shall,
promptly after becoming aware thereof and before further disturbing conditions affected thereby or performing any
Work in connection therewith (except in an emergency as required by paragraph 6.16.A). identify the OWNER of
such Underground Facility and give written notice to that OWNER and to OWNER and ENGINEER. ENGINEER
will promptly review the Underground Facility and determine the extent, if any, to which a change is required in
the Contract Documents to reflect and document the consequences of the existence or location of the Underground
Facility. During such time, CONTRACTOR shall be responsible for the safety and protection of such
Underground Facility.

2. If ENGINEER concludes that a change in the Contract Documents is required, a Change Order will be issued to
reflect and document such consequences. An equitable adjustment shall be made in the Contract Price or Contract
Times, or both, to the extent that they are attributable to the existence or location of any Underground Facility that
was not shown or indicated or not shown or indicated with reasonable accuracy in the Contract Documents and that
CONTRACTOR did not know of and could not reasonably have been expected to be aware of or to have
anticipated. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amount or extent, if
any, of any such adjustment in Contract Price or Contract Times, OWNER or CONTRACTOR may make a Claim
therefore as provided in paragraph 10.05.

3. CONTRACTOR shall notify the following underground utility locating service at least three full working days
prior to beginning work: Dig Safe System, Inc. 1-800-344-7233.

A list of the major public utilities servicing the work area follows. The list indicates the name and telephone
number of the responsible authority of the various utilities which should be notified if conflicts or emergencies
arise during the progress of the work.

Electricity - Eversource 1-800-662-7764

4. At points where the CONTRACTOR’s operations are adjacent to public and private utilities, CONTRACTOR
shall not commence work until CONTRACTOR has made all arrangements necessary for the protection of utilities.
5. CONTRACTOR shall coordinate and cooperate with the OWNER’s of any underground or overhead utility
lines in their removal and rearrangement operations in order that these operations may progress in a reasonable
manner, that duplication of rearrangement work may be reduced to a minimum, and that services rendered by those
parties will not be unnecessarily interrupted.

4.05 Reference Points
A. OWNER shall provide engineering surveys to establish reference points for construction which in ENGINEER’s

judgment are necessary to enable CONTRACTOR to proceed with the Work. CONTRACTOR shall be responsible for
laying out the Work, shall protect and preserve the established reference points and property monuments, and shall

GC - 14 of 53

make no changes or relocations without the prior written approval of OWNER. CONTRACTOR shall report to
ENGINEER whenever any reference point or property monument is lost or destroyed or requires relocation because of
necessary changes in grades or locations, and shall be responsible for the accurate replacement or relocation of such
reference points or property monuments by professionally qualified personnel.

4.06 Hazardous Environmental Condition at Site

A. Reports and Drawings: Reference is made to the Supplementary Conditions for the identification of those reports
and drawings relating to a Hazardous Environmental Condition identified at the Site, if any, that have been utilized by
the ENGINEER in the preparation of the Contract Documents.

B. Limited Reliance by CONTRACTOR on Technical Data Authorized) |. CONTRACTOR may rely upon the general
accuracy of the “technical data” contained in such reports and drawings, but such reports and drawings are not Contract
Documents. Such “technical data” is identified in the Supplementary Conditions. Except for such reliance on such
“technical data,” CONTRACTOR may not rely upon or make any Claim against OWNER, ENGINEER or any of
ENGINEER’s Consultants with respect to:

1. The completeness of such reports and drawings for CONTRACTOR’s purposes, including, but not limited to,
any aspects of the means, methods, techniques, sequences and procedures of construction to be employed by
CONTRACTOR and safety precautions and programs incident thereto; or

2. Other data, interpretations, opinions and information contained in such reports or shown or indicated in such
drawings; or

3. Any CONTRACTOR interpretation of or conclusion drawn from any “technical data” or any such other data,
interpretations, opinions or information.

C. CONTRACTOR shall not be responsible for any Hazardous Environmental Condition uncovered or revealed at the
Site which was not shown or indicated in Drawings or Specifications or identified in the Contract Documents to be
within the scope of the Work. CONTRACTOR shall be responsible for a Hazardous Environmental Condition created
with any materials brought to the Site by CONTRACTOR, Subcontractors, Suppliers, or anyone else for whom
CONTRACTOR is responsible.

D. If CONTRACTOR encounters a Hazardous Environmental Condition or if CONTRACTOR or anyone for whom
CONTRACTOR is responsible creates a Hazardous Environmental Condition, CONTRACTOR shall immediately: (i)
secure or otherwise isolate such condition; (ii) stop all Work in connection with such condition and in any area affected
thereby (except in an emergency as required by paragraph 6.16); and (iii) notify OWNER and ENGINEER (and
promptly thereafter confirm such notice in writing). OWNER shall promptly consult with ENGINEER concerning the
necessity for OWNER to retain a qualified expert to evaluate such condition or take corrective action, if any.

E. CONTRACTOR shall not be required to resume Work in connection with such condition or in any affected area
until after OWNER has obtained any required permits related thereto and delivered to CONTRACTOR written notice:
(i) specifying that such condition and any affected area is or has been rendered safe for the resumption of Work; or (ii)
specifying any special conditions under which such Work may be resumed safely. If OWNER and CONTRACTOR
cannot agree as to entitlement to or on the amount or extent, if any, of any adjustment in Contract Price or Contract
Times, or both, as a result of such Work stoppage or such special conditions under which Work is agreed to be
resumed by CONTRACTOR, either party may make a Claim therefore as provided in paragraph 10.05.

F. If after receipt of such written a notice CONTRACTOR does not agree to resume such Work based on a reasonable
belief it is unsafe, or does not agree to resume such Work under such special conditions, then OWNER may order the
portion of the Work that is in the area affected by such condition to be deleted from the Work. If OWNER and
CONTRACTOR cannot agree as to entitlement to or on the amount or extent, if any, of an adjustment in Contract Price
or Contract Times as a result of deleting such portion of the Work, then either party may make a Claim therefore as
