Subject: Dexter and Fairgrounds Lift Station Final Design Services for Inline Overwatch System Dear Mr. Nguyen:
As discussed with you, LEE + RO is pleased to submit this proposal for preparing final design engineering services for two (2) lift stations: Dexter LS and Fairgrounds LS . The two designs will be based on the In -Line Overwatch System per the City’s request. The final design will expand on current preliminary research efforts and will consist of new 90% and 100% submittals. Both designs assume that the existing lift stations will be demolished, and the new upgraded lift stations will be constructed in their place.
Please note that based on our conversation with you, the Overwatch based system will not have 2 hours of physical storage for the wastewater. Instead, battery storage capacity to provide a minimum of two hours of pumping capacity will be provided during SCE power outage event.
The proposed tasks requested for authorization per each lift station include the following:
1. Project Management, Administration, and QAQC for the duration of the project.
2. Preparation of final design documents for two (2) separate lift stations. Final design will include calculations, hydraulic analyses, and vendor coordination for the desired Overwatch system.
3. Preparation of construction ready drawings for the alternatives identified including site, mechanical, and electrical layouts at the 90 and 100% submittal phases including associated technical specifications.
4. Preparation of preliminary engineering estimates of probable construction costs.
FEE
LEE + RO proposes a total not-to-exceed fee of $142,546. We have enclosed a fee breakdown for the proposed work as Exhibit A. Thank you for this, and every opportunity. If you have any questions, please feel free to contact me via email at [email protected] or (626) 667-5309. We are including the Opinion of Probably Construction Costs for both the stations based on the current design we have and the Overwatch system that will help you understand the cost savings that the City can realize using the Overwatch system.
Respectfully submitted,
