Title
Joint resolution authorizing Modification Number One for Professional Services Agreement Number 20146 with RHMG Engineers, Inc., Mundelein, Illinois, to provide preliminary and final engineering services for the Des Plaines River Water Reclamation Facility Bar Screen Replacement Project and final engineering services New Century Town Water Reclamation Facility Bar Screen Replacement Project.
Staff Summary
• The Des Plaines River (DPR) and New Century Town (NCT) Water Reclamation Facilities (WRF) utilize metal bar screens to capture and remove debris from the sewage flow prior to the treatment process. The bar screens at NCT have reached the end of their useful life and need to be replaced.
• A recent inspection at DPR revealed severe deterioration of one of the bar screens and the need for replacement. This project will include the replacement of two bar screens at NCT and one bar screen at DPR.
• In January 2021 Lake County Public Works authorized a contract with RHMG Engineers, Inc. for the preliminary engineering services for the NCT Bar Screen Replacement in the amount of $49,110 and a subsequent agreement for $4,950 for DPR Bar Screen Assessment. The initial agreement for preliminary engineering services was intended to be amended to include final engineering services which is consistent with the County’s experience in multi-phase professional contracts.
• This contract modification will provide preliminary and final engineering design services for DPR and final engineering design services for the NCT. The additional scope authorizes RHMG Engineers, Inc. to design and prepare final engineering plans and specifications for process mechanical, structural, electrical and control items and to assist in the bidding process.
• Contract Modification Number One increases the amount of Engineering Design Services contract by $200,428 from $54,060 to $254,488.
• In accordance with Article 8, Section 101 (1) of the Lake County Purchasing Ordinance it is hereby requested that the Purchasing Agent be authorized to enter into Contract Modification Number One.
