Greenhouse Addition to Vail Mountain School
Vail, Colorado
Project No. 14.142
Dear Mr. Goulding:
Cesare was on-site on June 9, 2014 to observe the excavation for the greenhouse addition at Vail
Mountain School. The soils observed at foundation elevation consisted of clayey sand with gravel
and cobbles up to 12 inches in length. The excavation was about 3 feet deep. A walk behind
sheep's foot compactor was used to compact the bottom of the excavation. Pumping of the
foundation soils was observed in one area. The soils were excavated an additional 6 inches in the
area of the footing location and replaced with drier soils from the on-site stockpile. When the
replaced soils were compacted, no pumping was observed. We used the on-site plans, 'VMS —
Greenhouse, 3000 Booth Creek Falls Road, Vail, CO 81657", dated May 14, 2014 by Pierce
Architects. The plans indicate an assumed bearing capacity of 1,000 pounds per square foot (psf)
for the soils at the footing elevation. In our opinion, the foundation soils observed on-site conform
to the geotechnical design assumptions in the plans.
Please contact us with any questions or comments regarding this information.
Sincerely,
CESARE
