Attn: Mr. Rubin,
This letter summarizes the special inspection and materials testing services GROUND Engineering
Consultants, Inc. (GROUND) performed during construction of the Vail Marriott Chiller Room and Pumps
Project in Vail, Colorado. The special inspection and materials testing services were performed at times
scheduled by the Contractor and/or Subcontractors between August 26th, 2015 and September 9th, 2015.
During construction, structural steel welded and/or bolted connections were periodically observed during
construction by a certified welding inspector (CWI). Also, observations and testing were performed on the
expansion anchors, drilled and epoxied bolts and grout placement into existing CMU walls. The
observations and testing were completed at times scheduled by the Contractor or Subcontractor.
Based on the field observations to date, RFI’s received and/or project documentation received from the
design team, it is our opinion that the materials observed for the welded connections, anchor bolt
installation and CMU grout placements were in general accordance with project plans, specifications,
and/or applicable RFI’s.
The observations and materials testing as indicated above were performed periodically to provide data to
the Owner, Contractor and Subcontractors to assist them in evaluating the general compliance of the
materials and/or work with the contract documents at the times of our observation and testing. We did
not supervise, direct nor have any control over any of the Contractor’s or Subcontractor’s work. We were
not responsible for the Contractor’s or Subcontractor’s scheduling of our services, means, methods,
procedures, techniques, or sequences of construction, nor responsible for ensuring that any Contractor or
Subcontractor performed or completed the work in accordance with the contract documents or
construction industry standards.
If you have any questions concerning this letter, please contact our office.
Sincerely,
GROUND Engineering Consultants, Inc.

August 26, 2015
While on site, we observed Adams Construction placing grout into the cells of the existing east CMU wall for future placement of
epoxy anchor bolts to hold beam face plates. The cells grouted correspond to the north three bolts for each of the two face
plates. Six 8" CMU courses were grouted. Quikrete Non-Shrink General Purpose Grout was mixed at approximately 1 gallon of
distilled water per 50 lb. bag of grout mix. Four 3"x3"x6" grout samples were cast for compressive strength testing.
Chris with Adams Construction was notified of our observations.
