At your request, Terracon Consultants, Inc. (Terracon) has completed revised engineering
design of the proposed Mechanically Stabilized Earth (MSE) retaining walls for the proposed
First Chair to be located in Vail, Colorado. Our design services have been completed subject to
the Terracon Supplement to Agreement, 65095812, dated August 26, 2010. Engineering plans
and calculations used in the design of the retaining wall are attached. Sheet RW -1 of the
project plans provides the Technical Scope of Work, along with material requirements and
specifications for construction of the retaining wall.
The engineering design has been completed on the basis of information provided to Terracon
as outlined in Section 1.03 of the Technical Scope of Work as shown on Sheet RW -1 of the
' project plans. The engineering design has been based on the following geotechnical
parameters:

With this submittal, our engineering design services for the project are complete. The Technical
Scope of Work also calls for certain testing, inspection and post design engineering services.
Terracon is available to discuss the scope of work that you may require of us for post design
services on this project.
The recommended Quality Assurance plan for the project, as outlined in the Uniform Building
Code, International Building Code and the Building Construction and Safety Code, NFPA 5000
is provided in Section 3.11 of the Technical Scope of Work on Sheet RW -1 of the project plans.
