I am the Engineer of Record for the Dollar General Store located Stone Quarry Road in
Parachute, Colorado. I have reviewed the Testing Lab Report and the progress photos of the
concrete footings of the retaining wall associated with this facility. (See attached.) Please note
that the concrete testing results are for 7 -day breaks only and 28 -day testing will be available
until April 25, 2019. It is my understanding that there are no other unresolved construction
issues associated with the wall. On this basis and with the exception of the concrete strength, it
is my understanding that the wall has been constructed in conformance with our original design
intent.
Once the 28 -day concrete compressive strength results are known and assuming the
compressive strength is at least 4,000 psi, the construction should be considered satisfactory.
Given that the 7 -day compressive strengths were over 3,700 psi, we anticipate that the 28 -day
strength will be in excess of that required. If you have any questions, please let me know.
Sincerely,
Brad Watson, P.E.
