The Town of Bolton is seeking bids for the removal of a PVC culvert and the installation of an 8' foot wide by 5.5' deep box culvert with wing walls. The project includes a partially embedded precast box culvert, precast wingwalls, precast approach slabs, crash-compliant highway guard and associated transitions, roadway regrading and paving. The Town of Bolton Town Administrator / Board of Selectmen is the awarding authority. The existing outlet of West Pond on Long Hill Road consists of a single 40-foot long 24" diameter PVC pipe. The roadway pavement width is 18' to 24' wide. The crossing contains no subsurface utilities. Long Hill Road is functionally classified as a rural minor collector. Per email from Joseph Lynch "Clarification as to the number of sheets comprising the plan set of the bid documents. o The plan set contains 6 sheets; S-1, S-2, S-3, S-4, S-5, and S-6. o The notation made in the lower righthand corner on each sheet states "Sheet X of 7" is incorrect. There are not seven sheets." Per Scott Desrosiers " I will be providing a sheet pile cofferdam quote per the plan S-6 and boring on S-3. Based on the borings (type C), pond level, and a recent culvert replacement in Bolton, I will also be quoting a shoring box 38' x 35' x 10D (max dig depth) this provides 3'+,- clearance all around the culvert/ headwall construction. There will be 1 level of frame ( whaler), so clear opening will be 32" less that box dimensions. Box will include tight corners and be reasonably watertight. Overall disturbance to the roadway length will be 40' Allow 3-4 day to install and 2 days to remove. Price will include 1 months rental of equipment" Per Joe Lynch "Treatment of the shoulder restoration falls under...
