ws March 20, 2019 Mr. Rick DeGardner Public Works Director City of Lino Lakes 600 Town Center Parkway Lino Lakes, MN 55014 Re: Proposal for Design and Bidding Services Well No. 1 Rehabilitation Project City of Lino Lakes, MN Dear Mr. DeGardner: 0 We appreciate the opportunity to submit this letter proposal to the City of Lino Lakes to provide professional engineering services for the design and bidding of the proposed Well No. 1 Rehabilitation Project. The design team includes ten (10) team members consisting of a civil engineer, a structural engineer, an architect, process engineers, a mechanical engineer, an electrical engineer, and technicians that will provide civil, structural, architectural, process, mechanical, and electrical engineering services. Project Understanding Well No. 1 has been identified by Public Works staff as operating inefficiently, and in need of repair and equipment upgrades. A summary of the scope of improvements for Well No. 1 is described as follows: • Expand existing Pumphouse No. 1 with new chlorine, fluoride, and polyphosphate rooms. • Prepare CAD based drawings of the existing pumphouse building in addition to civil, structural, process, mechanical, and electrical drawings. • The mechanical system design for the pump room will consist of one -for -one replacement of existing HVAC systems. Air conditioning will be limited to the Pump Room. This air conditioning system will be determined after the electrical Toads are finalized. • The new building addition will be provided with mechanical systems as required to meet the space heating Toad and ventilation air change rate as determined after the space is fully developed. • Plumbing systems will generally will be limited to meet the needs of the new addition. • Fire protection system design for the chlorine room. • Development of standalone building HVAC controls systems including sequence of operations. Design HVAC temperature controls shall be "stand-alone" controls as opposed to a DDC BAS or a monitoring system. • The existing main switchgear and motor control center will be replaced. The new equipment will include a new motor control center with a 480vac, three phase, 200 amp main breaker, a standby circuit breaker mechanically interlocked with the main breaker and connected to an existing receptacle for a portable generator, a branch circuit breaker for well pump power, a motor starter and circuit breaker for the chlorine booster pump, and a stepdown transformer and lighting panel for general electrical circuits (lights, outlets, HVAC, etc.) A new 60hp VFD for the well pump will be installed adjacent to the motor control center.
