I. PURPOSE AND BACKGROUND
Imperial County Department of Public Works (ICDPW) is requesting proposals from qualified and
experienced professionals to provide on-call services. The selected firm(s) will assist the County with
various assignments for local, state, or federally funded projects. These services will be on an intermittent
basis.
The purpose of the Request for Proposals (RFP) is to provide ICDPW with the ability to obtain assistance
quickly during peak workload periods, staffing shortages, and when expedited/fast track support is needed
to satisfy the Department’s scheduling and needs. The County of Imperial will award multiple on-call
contracts to qualifying firms for Plan Checking Services. The term of the as needed, on call agreements
shall be for one (1) year, with the option to renew for up to (4) additional one-year terms. Unless otherwise
terminated by ICDPW, upon expiration of the initial year, the agreement shall automatically renew for
successive one (1) year terms for four (4) one year periods for a total of five (5) years.
Consultant hourly billing rates proposed at the time of award shall remain in effect for the initial one-year
term of the Agreement. Any proposed adjustment to hourly rates for subsequent renewal periods shall
require prior written approval from the Director of Public Works, or designee, before such rates may take
effect. Increased rates shall not be applied or invoiced without ICDPW approval, and any unauthorized rate
increase shall constitute a material breach of the Agreement and may be grounds for termination.
Each proposal will be scored in accordance with the Consultant’s qualifications and experience. The
aforementioned services will be conducted under a contract with the County of Imperial, hereinafter
referred to as "County" and the consultant entity, hereinafter referred to as "Consultant". The contract will
be regulated according to the provisions of all federal, state and local laws and ordinances that are
applicable. This includes compliance with prevailing wage rates and their payment in accordance with the
Davis Bacon Wage Determinations.
Note: The County enforces the American with Disabilities Act (ADA) using local, state and federal
guidelines and enforces the strictest of the ADA codes and regulations concerning existing and new facility
improvements.
Compensation for the as needed, on call, agreement shall be handled through task orders after consideration
of price quotes from consultants and will be financed through project specific sources.
The contract will be regulated according to the provisions of all federal, state and local laws and ordinances
that are applicable. This includes compliance with prevailing wage rates and their payment in accordance
with California Labor Code, Section 1774. All Service Providers and sub-consultant(s) shall pay all workers
not less than the general prevailing rate of per diem wages and the general prevailing rate for holiday and
overtime work as determined by the Director of the Department of Industrial Relations, State of California,
for the type of work performed and the locality in which the work is to be performed, pursuant to sections
1770 et seq. of the California Labor Code. Prevailing wage rates are available on the Internet at:
