1.Dimensions have been corrected. A revised sheet is being sent to Coppell including this and answers to items 2
& 3
2.Yes, the L bars are to be post-installed with epoxy adhesive.
3.This information has been added to Sheet 89 and would apply on the bridge deck also.

Subject: sandy lake rd questions
Delvin,
I have a couple questions coming from the plans.
1. Can you double check the dimensions in detail A, approach slab and abutment #1 on sheet 89. The numbers don’t all
add up.
2. On sheet 89 it calls for an L bar to connect the sidewalk to the deck. Due to the phased construction we are unable to
have that L bar sticking out of the deck. Because of the thickness of the slab and the panels we are left with a deck that
is only poured 4.5" thick. This does not allow us enough space to use a threaded coupling system. Do you have any
ideas as to a method that will work in this application. Could we epoxy a dowel bar after the deck is poured?
3. Is a detail needed for how the interior rail at the bike trail connects to the sidewalk. I think it will be similar to the
detail on sheet 86 but the sidewalk will be thinner.
Please clirify.
Thanks,
1
