The attached COR Infrastructure Design Services Proposal identifies the following not -to -exceed estimated costs. As noted on page 5, costs will be less if individual projects are combined and constructed as larger projects and not individually. • Design services costs for all identified improvements = $548,181 • Construction costs for identified 2023 improvements (not including streets and associated storm sewer, sidewalks, trails, sanitary sewer and watermain) = $5,874,000 On July 11 th when requesting City Council approval of plans and authorization to advertise bids, the engineer's estimate of construction costs for the major categories of construction related to The COR Mass Grading were presented as follows; • $5,741,620 for Grading • $1,499, 5 3 0 for Storm sewer • $112, 3 0 5 for Sanitary Sewer • $155,730 for Watermain • $7,509,185 Total Engineer's Estimated Costs The current engineer's estimate of construction costs for the major categories of construction related to The COR Mass Grading are as follows; • $ 6, 7 5 6,122 for Grading • $1,517,429 for Storm sewer • $131,130 for Sanitary Sewer • $166,860 for Watermain • $8,571,541 Total Engineer's Estimated Costs This latest estimate was prepared prior to issuing attached bid Addendum 1 which, among other things, extended the substantial completion date from October 30, 2023 to May 31, 2024. During the bidding process, contractors had called to express concerns related to the short schedule. After hearing these concerns, BMI and City staff met to discuss the project completion date. The City indicated that legislative action related to the funding source allowed for the completion date to be extended. The extended completion date is believed to be the primary factor in the lower bids received. Also, during the project design process, discussions with the City allowed the following additional items to be included in the project: • Approximately 35% more material to be excavated from the pond and placed on surrounding lots. • Installation of a trunk storm sewer system through this area of The COR. • Construction of sanitary sewer and watermain facilities along Zeolite Street and Ramsey Parkway. Construction -related services including preparing construction contract documents, attending the pre -construction conference, reviewing shop drawings and other construction related submittals, staking construction, assisting with construction administration, and observing construction activities as needed are not included in the above design services cost estimate. Attached is a separate construction services proposal submitted by BMI in the not -to -exceed amount of $222,187.00 to provide such services. As drafted, Resolution #23-176 authorizes and directs the City Administrator to accept the Construction Services Proposal submitted by Bolton and Menk, Inc. in the not -to -exceed amount of $222,187.00 for and on behalf of the City of Ramsey so a separate motion to accept this proposal is not required. Proposed COR infrastructure project funding sources include; . TIF 14 Bonds (street, sidewalk and trail costs) . Stormwater Funds (stormwater management costs) . Sanitary Sewer Funds (sanitary sewer costs) • Watermain Funds (watermain costs)
