This is EXHIBIT A, consisting of 8 pages, referred to in and part of the Agreement between Owner and Engineer for Professional Services dated , Engineer's Services Article 1 of the Agreement is supplemented to include the following agreement of the parties. Engineer shall provide Basic and Additional Services as set forth below. PART 1 — BASIC SERVICES The South Bend WWTP has three dry -pit, centrifugal raw sewage pumps originally manufactured by Worthington Corporation. Two pumps are duty pumps and the third is a standby unit. Pump No. 1 is driven by a natural gas engine and Pump Nos. 2 and 3 are electric motor -driven. Each of the three pumps is required to pump a minimum of 50 MGD and pumps raw influent from the pump wet well to the primary influent channel. The City desires for all three pumps to provide a minimum of 55 MGD capacity. Pump Nos. 1 and 2 were installed in the 1950s while Pump No. 3 came later in the 1970s. Pump No. 2 was rebuilt in 2006, Pump No. 1 was rebuilt in 2009 and Pump No. 3 was rebuilt in 2010. Arcadis provided the engineering services to rebuild Pump No. 1 and No. 3; these pumps are successfully achieving greater than 55 MGD and the City desires similar upgrades to Pump No. 2. Pump No. 2 has a smaller impeller than Pump No. 1 and No. 3 and needs to be upgraded to meet future needs. Following its rebuild in 2006, Pump No. 2 initially pumped at least 50 MGD, but the performance has been declining. Over the last several years, Pump No. 2 has deteriorated such that its maximum capacity has dropped to 45 MGD. Further reduction in capacity may result in the plant not being able to meet its permitted peak capacity of 77 mgd if for any reason Pump No. 1 or No. 3 are taken out -of -service. The City's experience is that when pumps start declining in capacity, it declines quickly. Due to its declining capacity, Raw Pump No. 2 is in immediate need of rehabilitation and is the focus of this scope. Under this scope of services, Arcadis will design the rehabilitation of Raw Pump No. 2. Power Plant Services Corporation recently inspected Pump No. 2, and the inspection report has been submitted to South Bend and made available to Arcadis. Based on an initial review of the inspection report, it appears that the pump is in good condition and can be rebuilt to deliver at least 50 MGD in its current condition and be compatible with the electric motor. By upsizing the impeller, it is expected that Pump No. 2 will provide 55 MGD capacity. It is assumed that the pump's suction valve and discharge gate are operable and can be utilized to isolate the pump during rehabilitation as part of this project. Arcadis will prepare bidding documents for the Raw Pump No. 2 project and provide assistance during bidding. Additionally, Arcadis will provide engineering services during the construction phase of the project. The City will provide a City employee that will serve as the Resident Project Representative at the site to provide more extensive inspection of the Work. The scope of engineering services shall include the following: 1. Project Management. Provide project management including scope, budget and schedule control; coordination with Client; maintenance of project records; project setup, invoicing, and close-out.
