(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: 1 1 C C 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.
