Background:
The original Agreement for Professional Consulting Services was for the production of a
Conceptual Design Memorandum that evaluated alternatives for the proposed rehabilitation project. Contract Amendment No. 1 was for the detailed design and production of bid documents for the selected alternative (a new combined headworks facility). Contract Amendment No. 2 added the detailed design of odor control facilities to the project. The construction contract for this project was awarded to Crossland Heavy Contractors, Inc. at the October 3, 2017 BAMA meeting. This Agreement for Professional Consulting Services Contract Amendment No. 3 adds Assistance During Construction Services (to include preparation of conformed contract documents, review of contractor submittals and change proposals, construction observation, site visits, Operations and Maintenance Manual preparation, plant operations training, startup/acceptance testing, and record drawings) for the project which will begin soon. The Engineer’s work will be performed at the direction of the E&C Department staff on a cost-plus basis for labor and direct cost for reimbursable expenses. A fee of $370,928.00 has been negotiated with the Engineer for assistance during Construction Services.
Funding for this agreement amendment is available in existing Oklahoma Water Resources Board (OWRB) Loan No. FAP-16-001L and Oklahoma Water Resources Board (OWRB) Financial Assistance Program Loan No. FAP-17-0004-L.
