CR 99-141 Approve Engineering Services Agreement Elmo Park Water Treatment Plant Renovation July29,1999 \ i Y 0 .. 1- c" o P K \ ~ Council Report 99-141 Approve Engineering Services Agreement Elmo Park Water Treatment Plant Renovation ProDosed Action. Staff recommends adoption of the following motion: Move that council authorize the City Manacer to enter into an acreeme"t with SEHRCM for the encineerinc services related to the renovation of the Elmo Park Water Treatment Plant. Overview. The Elmo Park Water Treatment Plant filters were installed in1967 and they are in need of renovation. The filter media is in need of replacement with new filter materials and the Wheeler Under Drain System is in need of renovation. Both of these systems have reached their normal life span limits. With the renovation work to these systems and the addition of an air wash and a backwash water recovery system the plant will serve the City of Hopkins for at least another 30+ years. PrimalV Issues to Consider. What is the estimated project cost? City cost? The estimated costs should be covered by the $395,000 that was entered into the Capital Improvement Plan. The cost of the engineering services is $60,437. Project schedule Complete design: September- October,1999 Award Project: November,1999 Construction: December-March, 2000 Engineering Selection Process and SEHRCM engineering fees Engineering proposals were solicited from three firms. We received proposals from all three fully qualified engineering firms: SEHRCM, TKDA & Associates and OSM & Associates. Staff selected SEHRCM based on their qualifications, and because RCM designed the plant originally and has been involved with numerous other up grades to the Water plant. SEHRCM fees total $60,437, including an estimated $ 25,237 for construction services. One other factor that was taken into consideration is the fact that their offices are about 10 minutes away which should help keep travel time costs down on inspection related visits to the site during construction of the project. All of the proposal costs were within 9% of each other. SUDDortinc Information SEHRCM Addendum to proposal . CIP Project Sheet "'serlCIII 10901 Red Circle Drive, Suite 200, P.O.

Lauseng Utility Superintendent City of Hopkins 11100 Excelsior Blvd. Hopkins, MN 55344 Dear Mike: Thank you for the opportunity to discuss the water treatment plant improvements project with you yesterday. The dialog was very helpful for us to understand your approach to the project more clearly. We have prepared the following comments and clarifications for your review. Scope & Fee Comparison Both SEH-RCM and TKDA have documented in their proposals how time has been budgeted for design and construction phase services. The design phase fees were similar, but a very different level of effort was proposed for construction phase services. Design Phase SEH-RCM has proposed a slightly lower fee than TKDA, and we are comfortable that we can provide a high quality set of bidding documents for this fee. Our efficiency likely comes from our past experience with tanks of similar style to the proposed tanle Our computer software that compares the cost of tank size and depth configurations apparently also reduced our proposed fee, and has a great potential to save overall project costs for the City. (See the item entitled: "Construction Cost Savings" in our letter at the front of our proposal.) Construction Phase SEH - RCM has proposed a higher fee than TKDA, but we also proposed 70 more staff hours during the construction of the proposed work. We proposed an "hourly not to exceed" fee during construction, since the actual time needed during construction is very uncertain. If a diligent and careful contractor wins the bid, much less time would be needed than if a careless or neglectful contractor wins the project. Short Elliott Hendrickson Inc.

Lauseng June 29, 1999 Page 2 The most significant difference between SEH.RCM and TKDA's proposal for construction phase services is in the time budgeted for shop drawing review. SEH. ReM appears to have placed a much greater emphasis on shop drawing review. While we expect that TKDA will provide this function as an assumed (though not budgeted for) task, we have a few reasons why we put a greater focus on this part of the construction phase services. First, anything done on paper is easier to change than work that has been built incorrectly. When facilities are constructed differently than the project design documents, based on an incorrect assumption of the contractor or other cause, the Owner is often stuck with the dilemma of lots of time spent fighting for changes, or accepting a deduct in the contract price and living with the problem for a long time. Contractors are almost always more willing to adjust items in the shop drawing phase. Second, competitive bidding climates tend to encourage lower quality shop drawings. When a General Contractor pushes suppliers and subcontractors to repeatedly lower their prices during and even after bidding, these sub's look for ways to cut costs. Recently we have seen this cost cutting appear in shop drawings that propose inferior quality items, neglect to provide all items specified, or tend to be vague and error- filled. We have worked diligently to protect our clients interests by requiring full conformance with contract documents during the shop drawing review phase. Sometimes this requires extra effort on first submittals and additional effort to review multiple re- submittals until the shop drawings meet the intent of the design. Proposed Adjustments With the overall fee differences in mind, we offer the following adjustments to our fee to show our good faith effort to meet the City's needs in a reasonable manner. 1. Adjust Shop Drawing Review Time. After our discussions, we looked closer at our estimated fee for shop drawing review. We believe that we can reduce the time required by 63 hours. This will reduce the fee by $5,540. With the remaining 96 hours budgeted, we can still provide a reasonably aggressive protection of your interests. 2. Average Quality Contractor. The quality of the successful low bid contractor is unknown. Because we have a history of not coming back to clients for additional fee, we added a 5 percent contingency into our estimated hourly fee for the construction phase. This allowed the flexibility of available time to deal with a poor contractor. Since the fee was proposed as "hourly not to exceed," a good contractor would require less time, and the City would not pay the extra 5 percent. Weare willing to delete this contingency with the assumption that we will be working with an average contractor. This will reduce the fee by $1,223 (after adjustment above). The resulting fees that we propose to use are as follows: Design Phase: Construction Phase $33,800 lump sum plus $1,400 estimated for expenses $24,537 hourly maximum plus $700 expenses Fee $35,200 Fee $25,237 Michael G. Lauseng June 29, 1999 Page 3 Conclusion We believe that we have offered the best qualified personnel to complete the treatment plant improvements desired by the City. Though our initial fee proposed was higher than those of the other firms that have submitted proposals, our scope was clearly more aggressive at protecting the City's interests during construction. We believe that the adjustments offered above bring our fees into a range closer to those of the other firms while still maintaining a moderately aggressive approach to protecting the City's interests. We appreciate the opportunity to discuss this project with you, and hope you give us the opportunity to serve as your engineer on this project. Sincerely, SEH.RCM ~v Dale A.
