Do you think that we need a set of the DART utility standard drawings
or
do you think that the written requirements explain it well enough?

Suzan,
Pay item #33 states that the contractor shall "fabricate, procure and
install 2 Utility Markers (one at each end) at each end of the
proposed
waterline as it crosses the DART ROW Each marker shall be 12x12
aluminum fastened to a metal post embedded in concrete The marker
shall meet both City and DART requirements
Section 6 9 'Utility Markers' of the DART standards outlines the
requirements.
6 9 UTILITY MARKERS Markers as shown in the utilities standard
drawings shall be used to indicate the location of below -grade
utilities
installations whether belonging to DART, private utilities companies,
or
local governments 6 9 1 Location Markers shall be placed at the
centerline of the facility being marked Lines beginning or ending
within the DART right -of -way shall be marked at their ends Lines
crossing DART right -of -way shall be marked at a point near the edge of
the subballast shoulder Track underdrains shall be marked at changes
in direction and at outflows Markers are not required for
underdrains
extending along bases or tops of retaining walls Markers, when
required, shall be placed on retaining walls in retained sections.
Where
a marker location, as prescribed above, results in a conflict with
other
underground facilities, the marker shall be placed away from the
trackbed at a point near the right -of -way line Utility markers are
not
required, however, for storm drains crossing under the DART trackway
when the storm drains can be readily located by trackside catch
basins,
manholes, or headwalls, or when the storm drains are so deep that they
will not be affected by trackway work. The section designer shall
indicate the location of utility markers on project plan drawings and
shall prepare a schedule of utility markers for facilities in their
Page 1
Suzan Taylor - Re 16-inch Line Page 21
project, defining the legend for each marker The schedule shall be
on
a project drawing 6 9.2 Description Utilities markers shall consist
of
a metal target plate mounted vertically on a formed metal post and
shall
be furnished and installed by the contractor The front face of the
target plate shall be marked as indicated on utilities standard
drawings, with the station number, a symbol identifying the type of
facility, and the utilities owner Markers located near the edge of
the
subballast shoulder shall be oriented so that the front face faces
away
from the tracks. Markers located away from the trackbed shall be
oriented so that the front face faces the tracks.
So the contractor is responsible for all materials, labor and
installation The city of Coppell standard water line utility sign
should be installed
I hope that this helps clarify this situation
Sincerely,

Doug
The water line utility markers that go on either side of the DART ROW
is the contractor supposed to supply those or are they something that
I
would need to ask the utilities department to supply Rick wants to
know what they are supposed to look like
Thanks
Suzan
