Please refer to the attached scope of work taken from the Capital Improvement Projects Report which describes the project in detail and the costs associated with the design, inspection and construction Also attached are comments from Boyle Engineering relating to the reasonableness of the costs shown in the report Boyle s report was obtained during the budget review period as an outside engineering firm' s comments to the District s 1992-93 Capital Improvement Program Therefore, it is proposed to complete the design of the project at the following hourly rates not to exceed $9 000 Engineering $ 59 00/hr Draftsman 47 00/hr 3 man Survey Crew 170 00/hr 2 man Survey Crew 150 00/hr Please note that billing will be only for actual time worked Sinceperely l Ro in B Hamers RBH/jp/proposal cms Encl 4: Panted on Recycled Paper ' rt.s r COSTA MESA. t DISTRICT , ti DIRECTORS Costa Mesa Recycles James A.

Green, Secretary Nate Reade Dick Sherrick Project 1112100-133 Pump Station Maintenance The project entails repair or replacement of various items at various pumping stations including 1 Adams Pumping Station and 23rd Street Pumping Station replace existing pumps with Flygt pumps to achieve uniformity in type of pumps throughout District Existing pumps are ABS and have served their useful life and are hard to service Entails installing new guide rail system at both stations Adams station also needs new check valves 2 Elden Pumping Station excavate and repair by-pass valve that allows flows from Tustin Pumping Station to by-pass the Elden Station 3 Congress Pumping Station replace existing guide rail brackets with new stainless steel brackets 4 President Pump Station attempt to use pumps taken from abandoned station at South Coast Plaza at President Pump Station Minimal maintenance has always been done at President station since it is part of overall pump station abandonment project Installation may require some piping changes An estimate of the project costs is as follows Design $ 9 000 Construction 110 000 Inspection 9 000 Reserve or Contingency 22 000 TOTAL $ 150 000 — 9 — P.O.

Project 1112100 131 Televising Sewer Line Discussions with District staff indicated that this is a service type project not construction. Therefore, normal design, construction and inspection percentages do not apply The estimated televising costs represents approximately 75,000 LF of pipe to be televised at$0.35/LF based on discussions with District staff. Because of the nature of the project and that District staff is needed at all times for clearing ahead of the camera, coordination, and supervision of the work, the District Engineer costs will be higher percentage wise, versus a design project. It is suggested that for future similar projects the first three items above be included in the project description to more clearly define the scope of work. Proiect 1112100 132 Reconstructing Various Sewer Lines Estimated design/construction engineering costs as well as contingency costs appear to be reasonable; 16% and 16% of estimated construction respectively Project description should include estimated number of locations and/or length of pipe, and/or average cost per location. This would provide any reader of the CIP with additional information supporting the estimated construction cost. According to District staff the approximate cost for a typical repair would be in the$5,000 $6,000 range. Project 1112100 133 Pump Station Maintenance Project description adequately describes what is to be done. Estimated design/construction engineering costs as well as contingency costs appear to be reasonable, 16.4% &20% of estimated construction respectively It might be beneficial, for future similar projects, to provide estimated construction costs per individual location as part of the project description. Project 1112100 134 Victoria Street Widening/Other City Projects Project description adequately describes what is to be done and what the estimated costs are for
