INSURANCE
Review this section carefully with your insurance agent or broker prior to submitting a bid or
proposal. See Insurance Checklist (part of the Bid Forms) for specific coverage applicable to
this contract. The term "Contract" as used in this section shall mean the Agreement covering
the work that is entered into between the City of Johnson City, Tennessee and the Vendor.
1. General Insurance Requirements:
1.1 The Vendor shall not start work under this contract until the Vendor has obtained at its
own expense all of the insurance called for hereunder and such insurance has been approved
by the City; nor shall the Vendor allow any subcontractor to start work on any subcontract
until all insurance required of the subcontractor has been so obtained and approved by the
Vendor. Approval of insurance required of the Vendor will be granted only after submission
to the Director of Purchasing of original, signed Certificate(s) of Insurance, General Insurance
Appendix, and Insurance Checklist or, alternately, at the City's request, certified copies of the
required insurance policies.
1.2 No acceptance and/or approval of any insurance by the City shall be construed as
relieving or excusing the Vendor, or the surety, or its bond, from any liability or obligation
imposed upon either or both of them by the provisions of the Contract Documents.
1.3 The City of Johnson City (including its elected and appointed officials, agents, and
employees) is to be named as an additional insured under all coverage except
Worker's Compensation and Professional Liability and the Certificate of Insurance or
the certified policy, if requested, must so state. Coverage afforded under this paragraph
shall be primary as respects the City, its elected and appointed officials, agents and
employees. The following definition of the term "City" applies to all policies issued under the
contract:
"The City of Johnson City, Tennessee together with all of its various
departments, bureaus, and agencies, as well as any affiliated or subsidiary
board, committee, or authority, including but not limited to the City of Johnson
City, Dept. of Education (A.K.A "Johnson City Schools")."
1.4 The Vendor shall provide insurance as specified in the Insurance Checklist contained in
this document. In the event that Vendor obtains insurance coverage that is broader than the
minimum required by this Agreement, this Agreement shall be deemed to require the broader
coverage, including but not limited to any greater limits and any excess or umbrella
coverages.

1.5 The Vendor covenants to save, defend, hold harmless and indemnify the City of Johnson
City, Tennessee together with its various departments, elected or appointed officials,
employees, officers, counsel, agents, and any and all other persons or entities acting on
behalf of the same (collectively the City) from and against any and all claims of any sort based
upon any theory of liability whatsoever, for any and all harm, loss, damage, injury, cost
(including court cost and attorney fees) charges, or other liability of any nature whatsoever,
however caused, resulting from or arising out of or in any way connected with the Vendors
performance or non-performance of the terms of the contract documents or its obligations
under the contract based upon any theory of liability whatsoever, including claims brought by
third persons, and further covenants to discharge all of the aforesaid persons and entities and
forever hold them harmless from the same. The foregoing obligation to indemnify and defend
shall continue in full force and effect after the aforesaid Vendor completes all of the work
required under the contract, until such time as the applicable statutes of limitation or repose
have expired.
1.6 The Vendor shall be responsible for the work performed under the Contract Documents
and every part thereof, and for all materials, tools, equipment, appliances, and property of
any description used in connection with the work. The Vendor assumes all risks for direct
and indirect damage or injury to the property or persons used or employed on or in connection
with the work contracted for, and of all damage or injury to any person or property wherever
located, resulting from any action, omission, commission or operation under the Contract, or
in connection in any way whatsoever with the contracted work, until final acceptance of the
work by the City.
1.7 Insurance coverage required in these specifications shall be in force throughout the
Contract Term. If the Vendor fails to provide acceptable evidence of current insurance
within ten days of written notice at any time during the Contract Term, the City shall have
absolute right to terminate the Contract without any further obligation to the Vendor and the
Vendor shall be liable to the City for the entire additional cost of procuring performance by
another vendor and the cost of performing the incomplete portion of the Contract at time of
termination. Vendor is required to provide the City with notice of cancellation, non-renewal,
or material change in coverage at least thirty (30) days prior to cancellation, non-renewal, or
material change in coverage."
1.8 Contractual and other liability insurance provided under this Contract shall not contain a
supervision, inspection or engineering services exclusion that would preclude the City from
supervising or inspecting the project as to the end result. The Vendor shall assume all on-
the-job responsibilities as to the control of persons directly employed by it and of the
subcontractors and any persons employed by the subcontractor.
1.9 Nothing contained in the specifications shall be construed as creating any contractual
relationship between any subcontractor and the City. The Vendor shall be as fully responsible
to the City for acts and omissions of the subcontractor and of persons employed by them as
it is for acts and omissions of persons directly employed by the Vendor.
1.10 Precaution shall be exercised by the Vendor at all times for the protection of persons
(including employees) and property. All existing structures, utilities, roads, services, trees
and shrubbery shall be protected against damage or interruption of service at all times by the
Vendor and its subcontractors during the term of the Contract, and the Vendor shall be held
responsible for any damage to property occurring by reason of its operation on the property.

request for alternate coverage, the specified coverage will be required to be submitted. If the
City permits alternate coverage, an amendment to the Insurance Requirement will be
prepared and distributed prior to the time and date set for receipt of bids or proposals.
1.12 All required insurance coverage must be acquired from insurers authorized to do
business in the State of Tennessee, and acceptable to the City. The insurers must also have
policyholders' rating of "B++" or better, and a financial size of "Class V" or better in the latest
edition of Best's Insurance Reports, unless the City grants specific approval for an exception
in the same manner as described in 1.11 above.

the policy or policies in force during the term of this contract and
evidence the purchase of this extended reporting period endorsement
