PROJECT:
Denton Tap Road; Coppell, Texas
W &A #:
94093
The method to restrain the 16" Water Line over the bridge crossing agreed with the City
is to install fabricated metal frames at each joint location excluding the two most outward
joints. A copy of the 8" wide metal bracket frame detail is attached. In the interest of
time since the line needs to be placed in service, the structural engineer coordinated
with a local fabricator to start manufacturing the frames. The frames are being
manufactured at American Steel and Aluminum in Grand Prairie. They should be
assembled by the end of the day. Contact Mr. Wayne Beason at (972) 264 -1533 to
coordinate picking up the frames. 314" stainless steel bolts will be needed to secure the
frame to the bridge deck. Please coordinate obtaining the stainless steel bolts. The
frame holes will be slotted somewhat to allow installation of the bolts. When the holes
are drilled in the deck for the bolts, it may necessary to increase the hole in the concrete
to also assist in giving room to align with the frame.
A copy of a plan showing the approximate locations for placing the metal frames is
attached. The frames need to be close to joint locations but need to be separated from
the frames. This will allow access to the frames for adjustments, maintenance or
disassemble if ever needed. The frames are 18" in width and the pipes have an O.D. of
17.4 ". The frames are sized to be placed by inserting them onto the pipe horizontally
then rotating the assembly vertically in line with the bolt holes. The frames will not
restrain the pipe from moving longitudinally, but will prevent lateral movement. The
pipes should be re- aligned and the frames placed in plan along the same centerline and
online with the pipe hanger centerline.
Please call me if you have any questions. Please coordinate with Garreth Campbell
regarding starting installation of the frames.
