OVERVIEW OF SELECTION PROCESS
* This is an On-Call agreement utilized for the performance of services for a number of projects under
task orders issued on an as-needed basis. The dollar value of each individual agreement cannot exceed
three million dollars ($2,000,000.00). There is no guarantee of actual agreement value.
* This is a single-phase solicitation process with the availability for discussions with up to four (4) of the
most highly qualified firms. Based upon the listed criteria and evaluation of each firm's submitted
proposal, the Selection Committee may decide if a small sample task and/or discussions will be held
with the most highly qualified consultants. If discussions are held, they will serve to clarify the technical
approach, qualifications, and capabilities provided in response to the RFP, after which the committee
will determine the ranking of the candidate firms.
* Selection Committee members will individually score each firm's submitted proposal which determines
individual ranking. DelDOT's ranking is the combined ranking of all Committee members. Firms, in
order of ranking, will have the opportunity to negotiate an agreement with DelDOT. If DelDOT cannot
reach agreement with the highest ranked firm(s), DelDOT terminates negotiations and begins
negotiations with the next highest ranked firm, and so on until an agreement is reached. DelDOT notifies
via email the awarded firm(s) of the opportunity to enter into an agreement with DelDOT. This
notification also includes information on the next steps for the agreement process.
* Selection Committee members may consider the Firm's prior or ongoing performance on Projects for
DelDOT in rating the Firm. The fact that a specific Selection Committee member or members have
experience with a Firm while other Selection Committee members do not, shall not be a reason to disqualify
any Selection Committee member or members. Selection Committee members may consider a Firm's
performance on currently assigned projects up to the closing date of the Selection Committee ranking
process.
* After the ranking process has been completed, applicable price information will be requested from the
successful candidate Firm(s), such as: salary rates for various classifications of personnel; and an
indirect cost derivation for the most current accounting period.
* Payroll burden and overhead will be computed on direct salary costs only (not including overtime) at
the consultant's audited rate, as per Federal Acquisition Regulations Part 31, and DelDOT policies.
Computer and CADD costs are not allowable as a direct cost to this project. Rate determination and
applicability are subject to audit by DelDOT. Additionally, candidates should be prepared for DelDOT
to work with your current accounting firm to provide information and backup documentation. Full and
immediate cooperation is required to avoid delays in execution of an agreement. Failure to cooperate
may result in breaking off of negotiations and moving to the next ranked firm.
* Selection Committee membership appointments are confidential. DelDOT's Professional Services
Procurement Manual may be viewed here.
