Re: Construction Observation and Testing — Final Compliance Report
Anheuser Busch - South Entrance Sign
Installation of Two (2) Friction Piers for Entrance Sign
2351 Busch Drive
Fort Collins, Colorado
EEC Project No. 1134066
Mr. Schaffer and Wallisch:
As requested, Earth Engineering Consultants, LLC (EEC) personnel provided construction
observation and testing services for the referenced south entrance roadway improvement project
on the premises of the ABInBev (Anheuser-Busch) of Fort Collins Brewery property. The
services performed were provided on an essentially full-time basis and included observations of
the two (2) friction pier installed on February 24, 2014 for the overhead entrance sign and testing
of cast -in -place concrete for the referenced project. The results of the site observations and
testing services completed by EEC personnel during the referenced period are included with this
report.
On February 24, 2014, EEC personnel provided observation services for the two (2) 42-inch
diameter friction piers for south entrance roadway overhead sign. Those services were
essentially provided on a full-time basis and included observations of friction pier diameter (42-
inches), depth to installation, (approximately 15 to 15-1/2-feet below site grades), friction pier
length,(total pier length with portion raised above site grades equaled 16-feet), presence of
groundwater, (observed at an approximately depth of 11-feet below site grades), and
displacement/dewatering methods, (driller slurry methodology and use of a concrete pump truck
to displaced water at surface), reinforcing steel, and testing of cast -in -place concrete.

The reinforcement in general, consisted of 12 #1 0 vertical rebar with 11 #4 horizontal ties evenly
spaced. The top portion consisted of two (2) rows of cross -tie reinforcement, in general
accordance with detail B-B/9021 as presented on the structural drawings. The reinforcement and
installation of the anchor rods were in general accordance with the. details 3/9021, A-A/9021 and
B-B/9021 of the Revised Structural drawings prepared by CSD Project No. FCB-18-C-9021 Rev.
2 dated January 30/2014.
During the friction pier installation phase, EEC performed observations and testing services of
the cast -in -place concrete as indicated on the enclosed daily report, (Test No. 3). The concrete
testing was performed in general accordance with American Concrete Institute (ACI)
specifications. Field testing performed on the plastic concrete included slump, air content, unit
weight, and concrete temperature. The ambient air temperature at the time of placement was
also recorded. A minimum of 5 (4" x 8") concrete test cylinders were cast from representative
samples for laboratory curing and compressive strength testing. Results of the field and
laboratory compressive strength tests results performed are included herein.
We appreciate the opportunity to be of service to you on this project. If you have any questions
concerning this report, or if we can be of further service to you in any other way, please do not
hesitate to contact us.
Very truly yours,
