218 <br />would prove competitive versus open cut due to the interest expressed, <br />219 <br />particularly by 3M in getting their product tested in the market. <br />220 <br />twenty (20) years down the road. While currently not having much supporting <br />221 <br />Regarding the future of the next Rice Street reconstruction phase, Mr. Schwartz <br />222 <br />cautioned that there were still no guarantees for the project's timing; and based on <br />223 <br />a relatively deep water main section adjacent to wetlands between Transit and <br />224 <br />County Road C and other soil concerns, in addition to the challenges with County <br />225 <br />projects of late, staff was not recommending a delay. If the bids came in too high, <br />226 <br />Mr. Schwartz advised that staff would not recommend moving forward with <br />227 <br />them; however, he expressed his anticipation that t will be competitive or <br />228 <br />lower than open trenching. <br />229 <br />230 <br />At the request of Chair Vanderwall, Ms. Giga addressed the spray on methods and <br />231 <br />any impacts to potentially brittle cast iron pipes, advising that even if those pipes <br />232 <br />are classified as fully deteriorated, th 'ning product will make it structurally <br />233 <br />sound. <br />234 <br />235 <br />At the request of Chair Vanderwall, Mr. Schwartz advised that re were no <br />236 <br />concerns for potential da rs in the excavation and lining equipment . side the <br />237 <br />pipes other than those p nes originally installed for wells serve g the <br />238 <br />Reiling family properties. <br />239 <br />240 <br />At the request of Chair Vanderwall, staff confirmed that both processes required <br />241 <br />pre - cleaning of the pipes, and there was no cost reduction if less clean -out was <br />242 <br />needed. <br />243 <br />252 <br />253 <br />Member DeBenedet noted the lack of experience to -date for lining products, <br />254 <br />estimating the full impact and its useful life experience was an unknown until <br />255 <br />twenty (20) years down the road. While currently not having much supporting <br />256 <br />documentation on how effective the products would be or how well they would <br />257 <br />perform, Member DeBenedet opined that it was worth taking a risk; and if that <br />258 <br />risk proved to be successful, the money normally spent on digging and replacing <br />259 <br />pipes could be used elsewhere. While there was a potential that the products may <br />260 <br />prove a poor choice, Member DeBenedet noted that this would serve as a learning <br />261 <br />experience as well, similar to previous methods considered new and inventive in <br />262 <br />years past. <br />263 <br />Page 6 of 13 <br />
