Project No. 16-7-485.01
Subject: Observation of Pier Drilling, Proposed Main Residence Decks and Porches, Big
Mountain Ranch, County Road 252, North of Rifle, Garfield County, Colorado
Dear Roger:
As requested, a representative of H-P/Kumar observed the pier drilling at the subject site on May
1 and 7, 2018 to evaluate the piers for foundation support. The findings of our observations are
presented in this report. The services are part of our agreement for construction observation and
testing for the project to Giard Homes dated December 5, 2017.
The piers for the house were previously drilled as reported in our summary letter dated February
19, 2018 under the above project number. Thirty additional piers were designed for support of
the residence decks and porches and are the subject of this summary report.
We previously conducted a preliminary subsoil study at the site and presented our findings in a
report dated November 7, 2016, Project No. 16-7-485, and provided design recommendations for
the drilled piers in a letter dated December 11, 2017, Project No. 16-7-485.01. The additional 30
design piers for the deck/porches designed by KRM Consultants consisted of twelve -inch
dimeter piers with four No. 5 reinforcement bars for each pier.
Our observations of the pier drilling for the 30 piers drilled as well as reinforcement placed in the
piers prior to concreting are provided on the attached construction activity and drilled pier
observation reports. The pier numbers on the observation reports refer to the pier locations

shown on the attached Figure 1. The piers were installed per our recommendations and per
KRM Consultant's design.
If you have any questions, please contact us.
