Pier Elevations
Dear Mr. Davis:
As you requested, a field survey was conducted on October 26, 1995, to verify the top elevations of fifteen
random piers. The following are the results of the survey:
Pier Number J Plan Elevation (fi) Field Elevation (fi) J Difference In ElevatiOn (ft)
B-8 451.58 450.98 0.60
D-5 451.58 451.00 0.58
D-7 451.58 451.02 0.56
E-3 451.58 451.02 0.56
F-7 451.58 451.13 0.45
F-11 451.58 450.98 0.60
H-6 451.58 451.07 0.51
J-7 451.58 451.10 0.48
J-10 451.58 451.03 0.55
P-3 451.58 451.03 0.55
P-6 451.58 451.03 0.55
P-IO 451.58 451.01 0.57
R-7 451.58 451.01 0.57
S.5-6.5 451.58 451.12 0.46
T-9.5 451.58 451.05 0.53
As noted in our letter dated October 5, 1995, contractors typically leave the piers 5 to 6 inches shorter than the
plan elevation of the floor slab. The difference in elevation between the plan elevations (451.58 feet) and the
field elevations will be eliminated when the floor slab of the tank is poured and connected to the piers. The top of
the pier must be cleaned and free from all debris before the connection is made. Enclosed is a pier layout map
with the location of the piers that were surveyed. We are available to discuss this further at your convenience.
Sincerely,
Matt Hickey, ~
