264 <br />Mr. Schwartz opined that, if the City chose to take that risk, it was somewhat <br />265 <br />reassuring that it do so with a company with the experience and reputation of 3M. <br />266 <br />methods (CIPP, 3M product, open -cut) to track cost benefits and to determine <br />267 <br />Discussion ensued regarding the use of the 3M product in Europe, now <br />268 <br />approaching ten (10) years; adoption of these processes more quickly abroad with <br />269 <br />less finger - pointing than in the U.S.; warranty period for the products typically <br />270 <br />one (1) year, with the public works industry now moving toward a two (2) year <br />271 <br />warranty, with some recent specifications not calling for a warranty, but calling <br />272 <br />for a correction period that could go on forever if the contractor was found <br />273 <br />negligent. <br />274 <br />currently included in the bid requests. <br />275 <br />PWETC members concurred that staff review the specific warranty periods being <br />276 <br />offered by bidders on these products and processes. <br />277 <br />278 <br />Member Stenlund, with concurrence by the Commission, requested that staff <br />279 <br />provide and maintain a research comparison contract table for all three (3) <br />280 <br />methods (CIPP, 3M product, open -cut) to track cost benefits and to determine <br />281 <br />whether the lining worked better in a 6" and /or 8" diameter pipe over time. <br />282 <br />Member Stenlund also requested that staff required that each bidder submit a <br />283 <br />discharge SWPPP to spell out in detail their site plan for operation of pit <br />284 <br />locations, rather than making assu tions on their intent. <br />285 <br />286 <br />Ms. Giga advised that the City currently required outside plans, but may consider <br />287 <br />an addendum with those items of value mentioned by Member Stenlund and not <br />288 <br />currently included in the bid requests. <br />289 <br />Page 7 of 13 <br />
