Exhibit A r CITY OF DECATUR DESIGN AND CONSTRUCITON ENGINEERING FOR THE STARR CREST PUMPING STATION IMPROVEMENTS SCOPE OF WORK The Starr Crest Pumping Station was built in 1965 to serve the Starr Crest Acres subdivision. The pumping station is owned by the City of Decatur and maintained under a contract by the Sanitary District of Decatur. The station is a Smith & Loveless package pumping station with a steel shell and 4" cast iron force main. The original ejector pumps were replaced in 1985 with submersible pumps. The station has a rated capacity of 85 gpm. The station discharges to a manhole at the north end of 31" Street and then flows to the Sanitary District of Decatur's Country Club Pumping Station. The pumping station and force main are 48 years old. The pumps are 28 years old. The Sanitary District has upgraded the power and control panel in recent years. The station is located in the backyard of a single family home. It is difficult to access and service. A service truck cannot reach the station. The control valves are located in the wet well and are inoperative. In fact the shut off valves, check valves and all the piping are located in the wet well. Although allowed in the 1960's, IEPA will not allow new pumping stations to have the control valves located in the wet well due to safety concerns. Operating records indicate the station does not have sufficient capacity for wet weather flow. Although the tributary sewers are strictly sanitary, there is believed to be a significant amount of infiltration and inflow. The City has investigated the sources of 1/1 and provided flow data to be used in determining the new pump station capacity. In preliminary meetings with the City Staff and SDD, it was decided by the City that the existing pumping station should be replaced with a new, custom built duplex submersible pumping station. It was also decided that the existing 4" cast iron force main should be replaced with a new 4" PVC force main and that it should discharge to the same manhole as the existing force main. Since these decisions have already been made,further investigation of the condition and operation of the existing pumping station and force main are outside the scope of this contract. In subsequent meetings with the City, it was determined that the new pumping station should be designed for the flows that are currently being experienced. BGM will perform the necessary field surveys to design an access drive to the pumping station, site the pumping station, design the new connecting sewer, and design the new pumping station and force main. BGM will size the pumping station based on flow data provided by the City; will work with the SDD to address operation and maintenance concerns; and will work with the Park District to minimize the impact on its property. BGM will meet with SDD Staff to review details of the improvements and how those improvements will affect their 0&M. BGM will review the site drawings with the Park District and incorporate its comments into the design. Construction plans and specifications necessary for Last Revised:05-15-2013 A-1
