3.0 OBJECTIVE

ALCOSAN is requesting qualifications statements for On-Call Engineering Services to establish

a pool of qualified firms capable of supporting a variety of ongoing and future projects and

activities administered by the Division of Engineering and Construction both at the ALCOSAN

plant and in the ALCOSAN conveyance system, as described further below in “Scope of

Services”.

Those firms that participate in this Request for Qualification (RFQ) process will be referred to

as “Proposers.” “Proposer” and its Subconsultants shall be referred to collectively as the

“Team”. The successful Team(s) shall be referred to as the “Consultant”.

Please note that Proposers are not required to show expertise for every scope item listed in the
