| Trunk Sewer Line Involves
Combination of Open Trench and Underground Drives |
PCL Civil Constructors Inc., San Diego, Calif., currently
is constructing approximately five miles of the Rose Canyon Trunk
Sewer in San Diego, Calif., under a $23.8 million contract with the
City of San Diego. The line is a combination of open-cut sections
and six underground drives. The underground drives, which account
for one-sixth of the total length, are required because in several
areas the line passes under Caltrans or railroad right-of-way property
where an open cut is not possible. In several other areas the
depth of the new sewer pipeline, as much as 45 feet, makes an open-cut
trench impractical, according to Rick Selensky, resident engineer
for the City of San Diego.
