Explanation
1. Need. This legislation authorizes the Director of Public Utilities to modify the professional engineering services agreement with ARCADIS U.S., Inc. (formerly Malcolm Pirnie, Inc.) for the Southerly Wastewater Treatment Plant New Headworks project. The ARCADIS U.S., Inc. modification amount requested under this ordinance is $28,000.00. The total contract amount including this modification is $18,686,045.77. The proposed contract modification provides funding for detailed design services and services during construction now needed for the decommissioning of the existing headworks facilities. The potential need for this work was foreseen and so stated in the original contract's legislation, and is therefore a planned continuation of the services originally included within the existing contract's scope of service. It is not deemed either feasible or reasonable to suspend this work with the entity currently under contract and undertake continuation of these services with another provider or procurement process. The cost of the modification is a continuation of the vendor's current pricing structure, as verified by City staff.
