Cleaning, Televising, and Other Rehabilitation Work for Storm and Sanitary Sewer Lines

Details are within the bid specification. Answers to Questions from Vendors: Since MS4 regulations do not allow water vacuumed from storm sewers to be decanted back into the storm sewer during cleaning, will the contractor be able to release filtered water removed during the pipe vacuuming process into a local sanitary sewer for both storm and sanitary work orders? Yes. Is it possible the storm sewer work would consist of outfall pipes that would require controls to prevent discharge while cleaning? No. Regarding Item # 9 Cementitious Manhole Rehabilitation, is there a minimum thickness requirement for the cementitious liner or is the thickness based solely on the manufacturer's recommendation? Manufacturer’s recommendation is acceptable. Regarding Item # 10 Manhole Chimney Seal, is there a maximum depth of each chimney that application will be required in? 2 feet is generally acceptable; however, we will consider the crew’s recommendation at the time of repair. Regarding Item #11 Epoxy Manhole Rehabilitation Alternate, is the contractor to assume direct application of the epoxy coating to the manhole walls or will the contractor need to resurface with cement to provide a profile prior to application of the epoxy? Only in areas deemed necessary by crew foreman, the contractor will need to resurface with cement. Regarding Item # 3 Protruding Pipe Lateral Removal, would the contractor be issued a work order to only cut a protruding tap or would that work be incidental to a cleaning and inspection scope that was issued? Basically, could the contractor be called out to cut just one tap as a standalone work order? This item would be associated with other work. You will not be required to cut one protruding pipe lateral at time. Business enterprises awarded an identical or substantially similar procurement contract within the past five years: None
