December 12, 2018 Kevin Hansen, PE City of Columbia Heights 637 38`' Avenue NE 2019 -2906 7533 Sunwood Drive NW Suite 206 Ramsey, MN 55303 -5119 Columbia Heights, MN 55421 RE: Proposal for Pump Station No. 3 (PS3) Upgrades Project - Conceptual Design Report Ph: (7631433 -2851 Fax: 1763) 427 -0833 Bolton- Menk.com Dear Mr. Hansen, Bolton & Menk, Inc. appreciates the opportunity to submit this proposal for providing conceptual design services for Pump Station No. 3 upgrades. SCOPE OF SERVICES The "Recommendations for Pump Station # 3" was provided to us by the City and outlines: a) Current Recommendations for the PS3 Upgrades Project, and b) Add Alternates to be evaluated separately in the report. Our scope of services is divided between these two categories, as outlined below. A. Conceptual Design & Cost Estimating Services: (for current Recommendations) We will review all the current recommendations and develop a conceptual design and an associated project cost estimate for the PS3 Upgrades Project. The recommendations will be separated into three categories for clarity: Electrical / Motors, Pumps, Valves, and Building. B. Cost Benefit Evaluation and Cost Estimatin Services; (for Add Alternates) Three Add Alternates are described below. We will perform the requested needs assessments, cost benefit evaluations, and cost estimating for each of these Add Alternates. 1. Keystone Retaining Wall — Perform a cost/benefit evaluation of: a. Repair or replace the wall, or b. Remove the wall and regrade the slope. 2. Standby Generator — Perform a cost/benefit evaluation of: a. Replace with a properly sized exterior unit, or b. Keep the existing generator in the building. 3. Heating System — Assess the appropriate changes, if any. As noted in your request for proposal, additional engineering services will be negotiated if any of these "Add Alternates" proceed to the conceptual design level. PROJECT TEAM APPROACH Columbia Heights and Bolton and Menk, Inc. can adopt a Project Team approach to cost effectively accomplish this work. Assumed contributions from the team members are outlined below: Ulan & Menk rs an equal Kevin Hansen, P.E. December 12, 2018 Page: 2 I. City Provided Data a) Pump Curves, b) As Built Drawings (as pdfs or CAD files), i. Electrical/Mechanical Sheets for PS3 ii. Process Plan View of PS3 iii. Site Plan and Section of Keystone Retaining Wall c) Xcel Energy contact information, and d) Description and SCADA output (tower levels, pump starts /stops, distribution system components, etc.) related to water hammer occurrences. II. Systems Integrator Services a) Provide contact information, b) Provide function description and or P &TD of changes, and a. Review said changes with City and Engineer via conference call c) Provide Cost estimate of collaboratively agreed upon changes. 1I1. Team Meeting— One Workgroup Meeting with all key members at the site. IV. Report Development— Assumes one meeting /call to review the draft report. SCHEDULE AND COMPENSATION We will begin work immediately after authorization, and will be complete by April 15, 2019. Compensation is proposed to be on an hourly basis, based on the actual hours worked. We propose to perform these services for the following not -to- exceed fees. Task Conceptual Design & Cost Estimating Services Cost Benefit Evaluation and Cost Estimating Services Total Not -to- Exceed Fee $12,800 $2,000 $14,800 Additional services will be invoiced based on actual hours spent at current billing rates. We look forward to continuing our work with the City of Columbia Heights. We are available to meet and discuss items related to this project at your convenience. Respectfully submitted, BOLTON & MENK, INC. Kevin P. Kielb, P.E. Principal Engineer ACCEPTED BY: City Manager ATTACHMENT Recommendations for Pump Station #3 Steve Nelson, P.E. Project Engineer DATE: 1- 11.1°4 Bolton & Menk is an equal oppartunrly employer. Recommendations for Pump Station # 3 4633 Ivanhoe Place 2019 Engineering Analysis / Report and Prelim Design. Electrical / Motors: • Replace 240 volt electrical service with 208 volt service. • Coordinate with Xcel Energy for new power supply. • Replace two standard drive 50 horsepower motors with VFD motors and controls. • Replace cabinets and electrical controls for pumps. • Relocate water pressure lines and pressure gauges so they are not in the electric control panel. • Replace /upgrade SCADA equipment. Coordinate design with Primex, our current SCADA vendor. • Improve interior lighting: replace all interior lighting with LED ceiling mounted lights. Add LED lights for control panel area. Pumps: • Replace or recondition 2 pumps. Pumps were installed in 2005. Valves: • Replace the two existing swing check valves. o Minimize water hammer and repeated failure alarms. • Replace three of four 12 inch gate valves. o Age -They were installed in 1965 and are difficult to turn. The 4th GV was replaced in 2007. Building: ■ Roof was replaced in 2018. • Provide a permanent dehumidification system. • Exterior Building — Report level only, determine need and cost for tuckpointing brick exterior, along with building envelope caulking. Add Alternates — (identify separately in proposal) 1 2. Keystone wall located on the northeast perimeter of the pump station is failing and needs to be replaced. Report level only, Provide cost /benefit evaluation and construction cost estimate of full replacement of the wall vs matching existing slope and fill. Evaluate minimum sizing for a standby generator. Provide cost /benefit evaluation and construction cost estimate to replace standby generator that is located inside the building with an exterior standby generator, including a sound deadening package appropriate for residential areas. • Reason 1. The current standby generator is very noisy. Disturbs the residents a block away. (ear plugs have to be worn in the building when the generator is running.) • Reason 2. The ventilators could be removed from the building and the building would be more energy efficient. • Reason 3. The current electrical control panel is in close to the proposed location for the outside generator. • Reason 4. The current generator could be auctioned. It is still in good condition. • Reason 5. Replacing the generator at same time as the electrical control panel makes sense from a construction standpoint. • Review heating needs for building. There are currently two gas heaters and two electric heaters in the building.
