Subject: Observation of Pier Hole Drilling, Proposed Shop Building, 899 Gage Road,
Garfield County, Colorado
Dear Ms. Cotter:
As requested, a representative of H-P/Kumar observed the pier hole drilling at the subject site on
January 3 and 4, 2018. We previously conducted a subsoil study for design of foundations at the
site and presented our findings in a report dated January 26, 2017, Project No. 17-7-111.
The building has been designed to be supported on 23 12-inch diameter piers with a minimum
embedment length of 20 feet and minimum penetration into bedrock of 5 feet, as recommended.
Pier hole drilling observations are provided in the attached daily reports. Based on our
observations, the piers were installed generally as recommended and should perform as intended.
Concrete was placed in the pier holes the same day they were drilled.
If you have any questions or need further assistance, please call our office.
Sincerely,
H-P~KUMAR
