I. General
The Town of Christiansburg ("Town") is seeking Expressions of Interest ("EOI") from qualified consulting
engineering firms to provide professional engineering term services for stormwater on-call services, consisting of
assigned tasks covering a broad range of stormwater planning, roadway design, traffic engineering,
survey/mapping/right-of-way, and grant and funding support services, including services from allied disciplines,
issued to the selected firm(s) by individual Task Order as needs arise. The full scope of services is described in
Section III of this RFP.
The Town intends to select one or more firms to provide these services using the Competitive Negotiation procedure
for professional services set forth in the Virginia Public Procurement Act ("VPPA"), Code of Virginia 2.2-4302.2,
and the architectural/professional engineering term contracting provisions of Code of Virginia 2.2-4303.1. The
resulting contract(s) will have a maximum total term of four (4) years, as described in Section IV of this RFP.
The Town reserves the right to accept or reject any or all EOIs received in response to this Request, to negotiate
with any qualified firm, and to modify, cancel, or reissue this Request for Proposals, in whole or in part, if the Town
determines it is in its best interest to do so. This Request does not commit the Town to reimburse any cost associated
with the preparation or submission of an EOI.
The Town reserves the right to alter the project delivery method or task assignment approach at any time during the
contract term. Any such change will be implemented through an additional Task Order or supplemental agreement,
with corresponding adjustments to scope and compensation, consistent with Section 5.5 (Contract modifications,
amendments, and change orders) of the Town of Christiansburg Procurement and Surplus Property Manual.
A firm submitting an EOI as a Prime Consultant shall not also serve as a subconsultant on any other team that
includes the same Prime Consultant's personnel or affiliated firms.

may not be exceeded:
* Initial Term. The initial contract term shall be one (1) year from the date of contract execution / Notice to
Proceed.
* Renewals. The contract may be renewed for up to three (3) additional one-year terms at the sole discretion
of the Town, for a maximum total contract term, including all renewals, of four (4) years.
* Annual Compensation Limit. The sum of all task orders / projects performed under the contract in any one-
year contract term shall not exceed $2,500,000.
* Per-Task Limit. The fee for any individual task order or project shall not exceed $500,000.
* No Carryover. Any unused portion of the annual compensation limit from one contract term shall not be

they are lower limits self-imposed by the Town of Christiansburg Procurement and Surplus Property Manual
