2. Proposed adjustments in the progress schedule that will change the Contract Times (or Milestones) shall be
submitted in accordance with the requirements of Article 12. Such adjustments may only be made by a Change
Order or Written Amendment in accordance with Article 12.

6.05 Substitutes and “Or-Equals”

A. Whenever an item of material or equipment is specified or described in the Contract Documents by using the name
of a proprietary item or the name of a particular Supplier, the specification or description is intended to establish the
type, function, appearance, and quality required. Unless the specification or description contains or is followed by
words reading that no like, equivalent, or “or-equal” item or no substitution is permitted, other items of material or
equipment or material or equipment of other Suppliers may be submitted to ENGINEER for review under the
circumstances described below.

1. “Or-Equal” Items:

If in ENGINEER’S sole discretion an item of material or equipment proposed by CONTRACTOR is functionally equal
to that named and sufficiently similar so that no change in related Work will be required, it may be considered by
ENGINEER as an “or-equal” item, in which case review and approval of the proposed item may, in ENGINEER’s sole
discretion, be accomplished without compliance with some or all of the requirements for approval of proposed
substitute items. For the purposes of this paragraph 6.05.A.1, a proposed item of material or equipment will be
considered functionally equal to an item so named if:

a. In the exercise of reasonable judgment ENGINEER determines that: (i) it is at least equal in quality,

durability, appearance, strength, and design characteristics; (ii) it will reliably perform at least equally well the
function imposed by the design concept of the completed Project as a functioning whole, and;

GC-210f55

b. CONTRACTOR certifies that: (i) there is no increase in cost to the OWNER; and (ii) it will conform
substantially, even with deviations, to the detailed requirements of the item named in the Contract
Documents.

2. Substitute Items

a. If in ENGINEER’s sole discretion an item of material or equipment proposed by CONTRACTOR does not
qualify as an “or-equal” item under paragraph 6.05.A.1, it will be considered a proposed substitute item.

b. CONTRACTOR shall submit sufficient information as provided below to allow ENGINEER to determine that
the item of material or equipment proposed is essentially equivalent to that named and an acceptable
substitute therefore. Requests for review of proposed substitute items of material or equipment will not be
accepted by ENGINEER from anyone other than CONTRACTOR.

c. The procedure for review by ENGINEER will be as set forth in paragraph 6.05.A.2.d, as supplemented in
the General Requirements and as ENGINEER may decide is appropriate under the circumstances.

d. CONTRACTOR shall first make written application to ENGINEER for review of a proposed substitute item
of material or equipment that CONTRACTOR seeks to furnish or use. The application shall certify that the
proposed substitute item will perform adequately the functions and achieve the results called for by the
general design, be similar in substance to that specified, and be suited to the same use as that specified. The
application will state the extent, if any, to which the use of the proposed substitute item will prejudice
CONTRACTOR’s achievement of Substantial Completion on time, whether or not use of the proposed
substitute item in the Work will require a change in any of the Contract Documents (or in the provisions of any
other direct contract with OWNER for work on the Project) to adapt the design to the proposed substitute
item and whether or not incorporation or use of the proposed substitute item in connection with the Work is
subject to payment of any license fee or royalty. All variations of the proposed substitute item from that
specified will be identified in the application, and available ENGINEERing, sales, maintenance, repair, and
replacement services will be indicated. The application will also contain an itemized estimate of all costs or
credits that will result directly or indirectly from use of such substitute item, including costs of redesign and
claims of other contractors affected by any resulting change, all of which will be considered by ENGINEER in
evaluating the proposed substitute item. ENGINEER may require CONTRACTOR to furnish additional data
about the proposed substitute item.

B. Substitute Construction Methods or Procedures:: \f a specific means, method, technique, sequence, or procedure of
construction is shown or indicated in and expressly required by the Contract Documents, CONTRACTOR may furnish or
utilize a substitute means, method, technique, sequence, or procedure of construction approved by ENGINEER.
CONTRACTOR shall submit sufficient information to allow ENGINEER, in ENGINEER’s sole discretion, to determine that
the substitute proposed is equivalent to that expressly called for by the Contract Documents. The procedure for
review by ENGINEER will be similar to that provided in subparagraph 6.05.A.2.

C. ENGINEER’s Evaluation: ENGINEER will be allowed a reasonable time within which to evaluate each proposal or
submittal made pursuant to paragraphs 6.05.A and 6.05.B. ENGINEER will be the sole judge of acceptability. No “or-
equal” or substitute will be ordered, installed or utilized until ENGINEER’s review is complete, which will be evidenced
by either a Change Order for a substitute or an approved Shop drawing for an “or equal”. ENGINEER will advise
CONTRACTOR in writing of any negative determination.

D. Special Guarantee: OWNER may require CONTRACTOR to furnish at CONTRACTOR’s expense a special performance
guarantee or other surety with respect to any substitute.

GC -22 0f55

E. ENGINEER’s Cost Reimbursement: ENGINEER will record time required by ENGINEER and ENGINEER’s Consultants
in evaluating substitute proposed or submitted by CONTRACTOR pursuant to paragraphs 6.05.A.2 and 6.05.B and in
making changes in the Contract Documents (or in the provisions of any other direct contract with OWNER for work on
the Project) occasioned thereby. Whether or not ENGINEER approves a substitute item so proposed or submitted by
CONTRACTOR, CONTRACTOR shall reimburse OWNER for the charges of ENGINEER and ENGINEER’s Consultants for
evaluating each such proposed substitute.

F. CONTRACTOR’s Expense: CONTRACTOR shall provide all data in support of any proposed substitute or “or-equal” at
CONTRACTOR’s expense.

6.06 Concerning Subcontractors, Suppliers, and Others

A. CONTRACTOR shall not employ any Subcontractor, Supplier, or other individual or entity (including those
acceptable to OWNER as indicated in paragraph 6.06.B), whether initially or as a replacement, against whom OWNER
may have reasonable objection. CONTRACTOR shall not be required to employ any Subcontractor, Supplier, or other
individual or entity to furnish or perform any of the Work against wnom CONTRACTOR has reasonable objection.

B. If the Supplementary Conditions require the identity of certain Subcontractors, Suppliers, or other individuals or
entities to be submitted to OWNER in advance for acceptance by OWNER by a specified date prior to the Effective Date
of the Agreement, and if CONTRACTOR has submitted a list thereof in accordance with the Supplementary Conditions,
OWNER’s acceptance (either in writing or by failing to make written objection thereto by the date indicated for
acceptance or objection in the Bidding Documents or the Contract Documents) of any such Subcontractor, Supplier, or
other individual or entity so identified may be revoked on the basis of reasonable objection after due investigation.
CONTRACTOR shall submit an acceptable replacement for the rejected Subcontractor, Supplier, or other individual or
entity, and the Contract Price will be adjusted by the difference in the cost occasioned by such replacement, and an
appropriate Change Order will be issued or Written Amendment signed. No acceptance by OWNER of any such
Subcontractor, Supplier, or other individual or entity, whether initially or as a replacement, shall constitute a waiver of
any right of OWNER or ENGINEER to reject defective work.

C. CONTRACTOR shall be fully responsible to OWNER and ENGINEER for all acts and omissions of the Subcontractors,
Suppliers, and other individuals or entities performing or furnishing any of the Work just as CONTRACTOR is
responsible for CONTRACTOR’s own acts and omissions. Nothing in the Contract Documents shall create for the
benefit of any such Subcontractor, Supplier, or other individual or entity any contractual relationship between OWNER
or ENGINEER and any such Subcontractor, Supplier or other individual or entity, nor shall it create any obligation on
the part of OWNER or ENGINEER to pay or to see to the payment of any moneys due any such Subcontractor, Supplier,
or other individual or entity except as may otherwise be required by Laws and Regulations.

D. CONTRACTOR shall be solely responsible for scheduling and coordinating the Work of Subcontractors, Suppliers,
and other individuals or entities performing or furnishing any of the Work under a direct or indirect contract with
CONTRACTOR.

E. CONTRACTOR | shall require all Subcontractors, Suppliers, and such other individuals or entities performing or
furnishing any of the Work to communicate with ENGINEER through CONTRACTOR.

F. The divisions and sections of the Specifications and the identifications of any Drawings shall not control
CONTRACTOR in dividing the Work among Subcontractors or Suppliers or delineating the Work to be performed by any
specific trade.

G. All Work performed for CONTRACTOR by a Subcontractor or Supplier will be pursuant to an appropriate agreement
between CONTRACTOR and the Subcontractor or Supplier which specifically binds the Subcontractor or Supplier to the
applicable terms and conditions of the Contract Documents for the benefit of OWNER and ENGINEER. Whenever any
such agreement is with a Subcontractor or Supplier who is listed as an additional insured on the property insurance

GC - 23 0f55

provided in paragraph 5.06, the agreement between the CONTRACTOR and the Subcontractor or Supplier will contain
provisions whereby the Subcontractor or Supplier waives all rights against OWNER, CONTRACTOR, ENGINEER,
ENGINEER’s Consultants, and all other individuals or entities identified in the Supplementary Conditions to be listed as
insured or additional insured (and the officers, directors, partners, employees, agents, and other consultants and
subcontractors of each and any of them) for all losses and damages caused by, arising out of, relating to, or resulting
from any of the perils or causes of loss covered by such policies and any other property insurance applicable to the
Work. If the insurers on any such policies require separate waiver forms to be signed by any Subcontractor or Supplier,
CONTRACTOR will obtain the same.

6.07 Patent Fees and Royalties

A. CONTRACTOR shall pay all license fees and royalties and assume all costs incident to the use in the performance of
the Work or the incorporation in the Work of any invention, design, process, product, or device which is the subject of
patent rights or copyrights held by others. If a particular invention, design, process, product, or device is specified in
the Contract Documents for use in the performance of the Work and if to the actual knowledge of OWNER or
ENGINEER its use is subject to patent rights or copyrights calling for the payment of any license fee or royalty to others,
the existence of such rights shall be disclosed by OWNER in the Contract Documents. To the fullest extent permitted by
Laws and Regulations, CONTRACTOR shall indemnify and hold harmless OWNER, ENGINEER, ENGINEER’s Consultants,
and the officers, directors, partners, employees or agents, and other consultants of each and any of them from and
against all claims, costs, losses, and 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) arising out
of or relating to any infringement of patent rights or copyrights incident to the use in the performance of the Work or
resulting from the incorporation in the Work of any invention, design, process, product, or device not specified in the
Contract Documents.

6.08 Permits

A. Unless otherwise provided in the Supplementary Conditions, CONTRACTOR shall obtain and pay for all construction
permits and licenses. OWNER shall assist CONTRACTOR, when necessary, in obtaining such permits and licenses.
CONTRACTOR shall pay all governmental charges and inspection fees necessary for the prosecution of the Work which
are applicable at the time of opening of Bids, or, if there are no Bids, on the Effective date of the Agreement.
CONTRACTOR shall pay all charges of utility owners for connections to the Work, and OWNER shall pay all charges of
such utility Owner's for capital costs related thereto, such as plant investment fees.

6.09 Laws and Regulations

A. CONTRACTOR shall give all notices and comply with all Laws and Regulations applicable to the performance of the
Work. Except where otherwise expressly required by applicable Laws and Regulations, neither OWNER nor ENGINEER
shall be responsible for monitoring CONTRACTOR’s compliance with any Laws or Regulations.

B. If CONTRACTOR performs any Work knowing or having reason to know that it is contrary to Laws or Regulations,
CONTRACTOR shall bear all claims, costs, losses, and 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)
arising out of or relating to such Work; however, it shall not be CONTRACTOR’s primary responsibility to make certain
the Specifications and Drawings are in accordance with Laws and Regulations, but this shall not relieve CONTRACTOR
of CONTRACTOR’s obligations under paragraph 3.03.

C. Changes in Laws or Regulations not known at the time of opening of Bids (or, on the Effective Date of the
Agreement if there were no Bids) having an effect on the cost or time of performance of the Work may be the subject
of an adjustment in Contract Price or Contract Times. If OWNER and CONTRACTOR are unable to agree on entitlement
to or on the amount or extent, if any, of any such adjustment, a Claim may be made therefore as provided in
paragraph 10.05.

GC -24o0f55

D. CONTRACTOR shall comply with all local laws, ordinances, and statutes, all provisions of the Revised Statutes
Annotated, all provisions of the federal Davis-Bacon Act for projects with federal funding, and all regulations
promulgated under either statute. Copies of the "City of Nashua Prevailing Wage Rates for Public Works", as
determined by U.S. Department of Labor and "General Wage Determinations," as determined by the U.S. Department
of Labor, are available for inspection at the City of Nashua Division of Public Works, 9 Riverside Street, Nashua, New
Hampshire. If the provisions of the Davis-Bacon Act apply, all employees of the CONTRACTOR must be paid not less
than the wage which is the greater of the Federal wage determinations. The hourly and daily rate of wages to be paid
each class of mechanics and workers must be posted on the project site in a place generally visible to the employees.

E. If the Davis-Bacon Act applies, CONTRACTOR shall furnish to the OWNER within seven days after payment date of
the weekly payroll period, a statement of wages paid for each of the CONTRACTOR’s employees or a payroll report. If
the Davis-Bacon Act applies, CONTRACTOR shall furnish to the OWNER within seven days after payment date of the
weekly payroll period, a statement of wages paid for each of any subcontractor's employees or a payroll report for
each subcontractor. The statement or report must include the CONTRACTOR’s certification of compliance with the
requirements of the supplementary condition. CONTRACTOR agrees that failure to comply with the portion of this
supplementary condition requiring CONTRACTOR to furnish a certified statement of wages or payroll report will, in
addition to any other retention allowed under this contract or under state or federal law, allow the OWNER to
unilaterally, without notice to CONTRACTOR, retain an amount of up to 10% from each progress payment until the
OWNER determines CONTRACTOR has complied with the provisions of this supplementary condition.

F. If the Davis-Bacon Act applies to work to be performed under this contract, CONTRACTOR shall furnish to the
OWNER within seven days after payment date of the weekly payroll period, a statement of wages paid for each of
CONTRACTOR’s employees and for each of any subcontractor's employees or a payroll report from CONTRACTOR and
from each subcontractor. Each statement or report must include the certification by CONTRACTOR of compliance with
the provisions of the Davis-Bacon Act.

G. Workers’ Compensation Coverage.

229 Main Street

Nashua, NH 03060

2. CONTRACTOR agrees to maintain required workers’ compensation coverage throughout the entire term of the
contract. If CONTRACTOR does not maintain coverage throughout the entire term of the contract, CONTRACTOR
agrees that OWNER may, at any time the coverage is not maintained by CONTRACTOR, order the CONTRACTOR to
stop work, suspend the contract, or terminate the contract. For each six-month period this contract is in effect,
CONTRACTOR agrees, prior to the expiration of the six-month period, to provide another written request to its
insurer for the provision of a certificate and notice of lapse in or nonpayment of coverage. If CONTRACTOR does
not make the request or does not provide the certificate before the expiration of the six-month period,
CONTRACTOR agrees that OWNER may order the CONTRACTOR to stop work, suspend the contract, or terminate
the contract.

H. To be deemed a responsive bid, the list of subcontractor form must be submitted even if no subcontractors
are required to be listed. Submittal is as follows:
