The reactions for the new building do not change the recommendation used in the original report. The
existing foundation appears to be adequate to support the new steel building.
If you have any questions, or need additional clarifications please let me know.

Dear Mike.
As we discussed, you propose to remove a portion of the existing coal storage superstructure and install a new
steel building in its place using the existing building foundation. There appears to be no record drawings or
details of the existing building structural elements. In order to do a complete and detailed evaluation the
foundation elements would need to be expose and measured. There would also need to be a site subsurface
soils investigation to verify the allowable soil bearing pressure. The soils investigation could be done after the
footings were exposed.
The existing footings are assumed to be 20- 30 feet below the ground surface, and excavation to access them
for investigation would be difficult. It was agreed that an alternate method would be used for this evaluation.
This alternate method includes estimating the column base reaction for the existing superstructure and
comparing them with the column base reactions for the proposed new steel building. If the new steel building
reactions are equal to or less than the existing building reactions, it would be reasonable to assumed that the
existing foundation is adequate to support the new steel building. The existing coal storage structure has been
in place for many years with no signs of subsidence, deflections, or distress.
Using this alternate method, I have completed the evaluation of the existing coal storage building foundation
system relative to the installation of a new pre-engineered metal building. Using the existing steel frame
dimensions that you provided I estimated the vertical and horizontal reactions that would be applied to the
existing foundation. 1 then compared these reactions with the estimated column base reactions for the
proposed steel building provided by Sentential Building Systems.
1 have assumed that the new building will be anchored to the existing foundation at the same locations that
the existing building is attached. I have also assumed that the design Loads for snow, wind, and seismic will
be the same for both buildings. 1 included an estimated load for the coal conveyor that was originally a part
in the coal storage superstructure. It appears that the balance of the coal storage superstructure is basically
in its original condition except for the backfill in the coal chute area.
The results Indicate that the proposed steel building reactions are less than the existing building reactions by
about 20%. It appears that the existing foundation system will adequately support the proposed new building
structure.

Since the reactions for the new building are estimates, the final reactions should be reviewed to confirmed
once the final drawings are available.
If you need a more detailed analysis the existing building foundation will need to be exposed, measured, and
a site soils report obtained.
If you have any questions, or need additional clarifications please let me know.
Sincerely,
Stephen A. Kesler, P.F.
