It appears from a field visit that the utility pole at approx station 111+60
(right) is within the structure excavation necessary for the planned
retaining wall.

Above utility pole does not seem to have a conflict with the necessary excavation for the planned retaining wall, given a possible implementation of a temporary retaining system. In accordance to section 10-1.16 "OBSTRUCTIONS" of the Special Provisions, Utility Company Work.  The work described in "Relocation Work" will be performed by the utility company after the associated site preparation work has been competed by the Contractor.  The work listed in "Work to be performed by the Utility Company" is the minimum anticipated work.  The actual work may vary from that listed.

Plan Sheet / Specification Reference=Item 30, Spec Prov. page 86, 5-1.21

Question= "prior to the migratory bird nesting season of 2/15 through 9/1 veg. mowing......shall be completed..."  This conflicts with other paragraphs allowing work if no birds are present.  Please explain.

Should the contractor discover any evidence of bird nesting, while performing work outside the restricted areas of work, during the nesting season, the contractor shall not disturb the nesting birds or nests, and shall immediately stop work and notify the Engineer.

Plan Sheet / Specification Reference=Plan Sheet U-1

Question=It appears that shoring will be likely for the R-1 Wall.  Does the state have  additional information re the depth of the sewer line, which looks to be in conflict with the shoring?

AS-BUILT plans are available and can be downloaded for printing from the link above at any local printing firm or on your own printing equipment, and they look best when open in "photo imaging":

Plan Sheet / Specification Reference

Question=The as build drawings, provided by the web site, for the sewer line
near rw-1 show two 4" force mains, one at 20' right center line and another
at 25'.  This is assuming the center line of 67 shown on the as built and
the contract plans are the same.

This may place the sewer line in the footing of the retaining wall or in the
structural section.  The as builts provided do not show the profile of these
lines.

The utility plan U-1 showes the conflidting sewer line to be a 200mm.  Who
is correct?

  • The two 4" force mains are on oposit side of the centerline of Rte 67. The 8" (200 MM) sewer line is on the same side as the retaining wall.
