  • ECS has developed the ECS Consultant Contract Manual to incorporate recent updates to state and federal regulations regarding the administration and management of professional services contracts, including recent changes from updates to 23 CFR Part 172.  Implementation of the new ECS Consultant Contract Manual is effective June 20, 2016 and replaces the utilization of the ECS Contract Award and Administration Manual.
  • In collaboration with ADOT BECO and to ensure continued compliance with 49 CFR Part 26, ECS has made revisions to the following * DBE forms:
    • Add/Remove Subconsultant Request Form (*used for non-DBE and DBE subconsultants)
    • DBE Intended Participation Affidavit (Formerly DBE Intended Participation Affidavit-Subconsultant)
    • DBE Intended Participation Affidavit - Summary (Formally DBE Intended Participation Affidavit- Consultant)
    • Certification of Good Faith Efforts
    • SOQ Proposer’s Solicitation List – Deleted; no longer in use

    Effective immediately, consultants and subconsultants shall utilize these new forms on all existing and new contract submittals. Submittals utilizing old forms/formats shall be returned to the consultant(s) and the subconsultant(s) to be revised and resubmitted . To access and view, please visit ECS General Forms and ECS DBE Program Forms. Also effective immediately, the SOQ Proposers Solicitation List no longer needs to be submitted with future SOQ Proposal(s) because a Bidders/Proposer's List must be completed and submitted online at AZ UTRACS prior to the submittal of the consultant’s initial cost proposal.
