and connect said service lines to the relocated main.
• Sanitary Sewer Service Reconnection Sheet—The ENGINEER will prepare
sanitary sewer service reconnection plan sheet for existing services affected by the
sewer line relocation
• Details Sheet—The ENGINEER will prepare standard and special detail sheets for
water line and sewer line installation or replacement that are not already included

reroute the existing private sanitary sewer service line due to the abandonment or
realignment of the existing public sanitary sewer lateral or main: The CITY shall
furnish the ENGINEER with a sample format of how the sewer service line
reroute/relocation should be designed and submitted for construction. Additional
survey is not included in this scope. If the service flow line information has not
been obtained during previously completed design survey, the ENGINEER shall
delay the design of the sewer service line until after a Quality Level A Subsurface
Utility Engineering (SUE investigation has been performed). The Level A SUE will
be performed; (1) by the CITY prior to bidding if the CITY determines that it is
needed for satisfactory completion of the design; or (2) by the Contractor after the
project has been bid, by means of a bid item to that effect. In all options, the
ENGINEER shall propose appropriate de-hole locations in the project and collect
flow line elevation and other applicable information of the sewer service line. The
ENGINEER shall use this information to provide the design for the sanitary sewer
service line to be rerouted or relocated.
ASSUMPTIONS

Design and can be reviewed informally outside the City's normally scheduled
review meetings.
