City of Whitefish Department of Public Works 418 E. 2nd Street I PO Box 158 Whitefish, MT 59937 (406) 863-2460 I Fax (406) 863-2419 December 10, 2019 Mayor Muhlfeld and City Councilors City of Whitefish Whitefish, Montana Mayor Muhlfeld and Councilors Award of Wastewater Treatment Plant Construction Contract to Swank Enterprises Introduction/History The City was issued an Administrative Order of Consent (AOC) by the Montana Department of Environmental Quality (DEQ) on October 5, 2012. The AOC currently includes a Compliance Plan detailing the completion dates that must be met in order to bring the WWTP into compliance with updated requirements for removal of ammonia, nitrogen and phosphorous in the city’s updated wastewater discharge permit. As part of the AOC, the Whitefish City Council approved a Preliminary Engineering Report (PER) in 2016 recommending that a mechanical wastewater treatment facility be designed and constructed in the location of the city’s existing wastewater lagoons. Current Report The type of wastewater treatment plant selected for construction in the Whitefish wastewater system planning process is called a Sequencing Batch Reactor, or SBR. An SBR is a type of activated sludge plant where multiple unit processes are contained within the same concrete basin, saving space and cost. Generally, when selecting a SBR system, an engineer will bid the equipment initially and design the treatment plant around a specific type of equipment, allowing for a better and more cost-effective design. The equipment was bid in September 2018 and we received seven different bids from five vendors. Upon consideration of all the pertinent factors, the scoring of proposals was extremely close for two types of treatment processes - the Sanitaire SBR process and the Aqua-Aerobic AquaNereda (Nereda®) system. While the Nereda® equipment bid was greater than the others, the system requires much smaller basins, and a significant reduction in overall footprint. ---PAGE BREAK--- Re: Award of Wastewater Treatment Plant Construction December 10, 2019 Page I 2 of 3 Consequently, after factoring in concrete and foundation expense, the Nereda® system ultimately was the least expensive overall option. Additionally, the operating costs for the Nereda® system were projected to be much less than the Sanitaire system due to lower energy requirements. In more practical terms, this technology will allow us to build smaller basins which are less than ⅓ the size of more traditional SBR basins, allowing for construction savings, reduced energy consumption, and more effective use of the land at the treatment plant site. The much smaller footprint allowed moving the treatment plant outside of the existing treatment lagoon cells, resulting in further cost savings. The City ultimately decided on the Nereda® system and the equipment contract was awarded to Aqua-Aerobic on December 3, 2018. Once the equipment procurement process was complete, the City was able to proceed with the final design for the wastewater plant improvements. The goal was to complete the design and advertise the project for bids last summer, however, the complexity of the process and the fact that Whitefish is the first “greenfield” Nereda project in the U.S., required significant communication between our design engineers, and Aqua-Aerobics and developers of the proprietary technology – Royal in the Netherlands. Early in the design phase, it was determined that improvements were necessary for the effluent outfall and diffuser, sludge drying beds, and Administration Building so the overall project scope was adjusted to incorporate these needs. Ultimately, plans were completed in September and submitted to DEQ for approval. Final approval was received from DEQ on October 16, 2019. Financial Requirement Once the plans were approved by DEQ, the construction of the wastewater plant was advertised, and bids were opened on Tuesday November 19. A total of two bids were received ranging from $20,370,000 (Swank Enterprises) to $23,145,616 (Dick Anderson Construction). The engineer’s estimate was $16,683,973, meaning bids exceeded the estimate by 22% - 39%. The assessment of the bidding process indicates that several factors may have impacted the bid including limited number of bidders, other similarly-sized projects bidding at the same time, project complexity, use of proprietary technology, impact of the American Iron and Steel requirements, expensive dirt work and the involved control system. The low bidder, Swank Enterprises, spent a lot of time investigating the project and asking questions so we do believe that their bid is an accurate representation of the true cost of the project, in the current bidding climate. The Nereda® system was estimated to be $1.3 million less in capital costs when considering concrete and foundation cost differences. Upon receipt of the schedule of values from Swank, a calculation was performed to determine if the Nereda® system would provide this much savings. Net estimated capital cost savings resulting from choosing the Aqua technology over Sanitaire was estimated at $2.29M. Staff also worked with our engineers to determine whether there are elements of the project that could be eliminated or modified. While this “value engineering” exercise proved that the ---PAGE BREAK--- Re: Award of Wastewater Treatment Plant Construction December 10, 2019 Page I 3 of 3 system we design was extremely streamlined, we were able to identify approximately $475,000 in work that can be eliminated. Here is a brief description of those recommendations: 1. $334,461 - Omit all drying bed restoration The project included the restoration of the three biosolids drying beds at the plant. While this work needs to be completed, staff believes it can be done using city crews at a reduced cost. 2. $35,785 - Omit hauling and disposal of lagoon cell 3 sludge The contractor will move wet sludge to one of the existing drying beds for the city crew to remove at its convenience after significant dewatering has occurred. 3. $50,230 - Omit plant decommissioning Leave lagoon cells 1 and 2 as they are. Leave air piping to cell 2. Leave contents in flocculating clarifier. City would be responsible for pumping approximately 24MG of water to the drain to MLS or to the grit channel. 4. $54,733 - Provide continuous venting strips in lieu of specified vent/drain Liner system for biosolids basin would be modified to include fabric strips capable of minimizing gas accumulation beneath the liner. In total this exercise provided $475,209 in potential savings. An updated budget has been provided which incorporates these value engineering changes, final engineering fees, contingency, and tipping fees for landfill disposal of biosolids. Recommendation After continuous discussion between city staff, our engineers, Swank Enterprises, and Aqua Aerobic over the past month, the Public Works Department is confident that it is in the best interest of the city for Swank Enterprises to build the wastewater treatment plant. Swank is a reputable firm that has successfully completed countless projects throughout Montana. In addition, the plant that has been designed and bid is the most cost-effective solution to regain compliance with DEQ and will serve the city for decades to come. Based on these factors, it is the recommendation of the Public Works Department that Council award the Wastewater Treatment Plant Construction Project to Swank Enterprises in the amount of $20,370,000. As soon as the project is awarded, a change order will be executed reducing the contract price to approximately $19,895,000 based on final value engineering negotiations.
