Mr. Schwartz opined that, if the City chose to take that risk, it was somewhat reassuring that it do so with a company with the experience and reputation of 3M. Discussion ensued regarding the use of the 3M product in Europe, now approaching ten (10) years; adoption of these processes more quickly abroad with less finger-pointing than in the U.S.; warranty period for the products typically one (1)year, with the public works industry now moving toward a two (2) year warranty, with some recent specifications not calling for a warranty, but calling for a correction period that could go on forever if the contractor was found negligent. PWETC members concurred that staff review the specific warranty periods being offered by bidders on these products and processes. Member Stenlund, with concurrence by the Commission, requested that staff provide and maintain a research comparison contract table for all three (3) methods (CIPP, 3M product, open-cut)to track cost benefits and to determine whether the lining worked better in a 6" and/or 8" diameter pipe over time. Member Stenlund also requested that staff required that each bidder submit a discharge SWPPP to spell out in detail their site plan for operation of pit locations, rather than making assumptions on their intent. Ms. Giga advised that the City currently required outside plans, but may consider an addendum with those items of value mentioned by Member Stenlund and not currently included in the bid requests. At the request of Member Stenlund, Ms. Giga addressed the de-watering pits indicated for each process; chemical management clean-up costs; pipe flexibility before and after either type of lining; any cracking data available; whether the lining (e.g. MSDS on chemical-based products, and other variables. Member Stenlund expressed his significant interest in the 3M product, noting the interesting opportunities becoming available with these new technologies. While the 3M product could provide lining up to 36' without a pit, Ms. Giga noted that the City needed to replace some valves with the project anyway, and both processes allowed could line through the valve and bypass some old ones for cut- in and replacement in a better location. Member Gjerdingen arrived at this time, approximately 7:20 p.m. Recess Chair Vanderwall briefly recessed the meeting at approximately 7:21 p.m. and reconvened at approximately 7:25 p.m. 7.
