1.0 INTRODUCTION AND EXECUTIVE SUMMARY

We are pleased to introduce our firm, KHATRI International, Inc., to your organiza- tion. Khatri International, Inc. is a civil and structural engineering company based in Pasadena, California. Our project experience covers general building design, structural engineering, seismic design, structural tower design, civil engineering and infrastructure work including pipeline, reservoir design, flood control facilities, storm drain, water pump stations, and construction management aspects.

Over the past ten years we have developed a specialization in wind tower design and analysis with a particular emphasis on the design of wind tower foundations. We are well versed in all types of wind tower foundations, from spread footings to designs utilizing rock anchors. Our unique experience gives us the ability to value engineer the most cost effective foundation solution for an individual site, and then implement that solution through final design and construction.

We have worked on over 2000 MW of wind tower projects in the US and Canada and signed as Engineer of Record for the towers and foundation systems. We maintain PE licenses in 50 states.

CARL D. SCHRENK SOUTH COAST GEOTECHNICAL SERVICES

EDUCATION AND LICENSES State of California Certified Engineering Geologist, No. 900 State of California Registered Geologist, No.3101 State of Arizona Registered Geologist, No. 7156 State of Utah Professional Geologist, No. 7153623-2250 BS, Geology, University of Utah, Salt Lake City, Utah As Branch Manager and senior engineering geologist of (ESSW), Mr. Schrenk oversaw the operations of the San Juan Capistrano office. He is experienced in performing and coordinating geologic/geotechnical exploration field studies, evaluating and preparing samples for laboratory testing, analyses and report preparation, review and performing services during construction. He has over 38 years of professional experience in all phases of geotechnical engineering from project inception to construction. Mr. Schrenk was also responsible for new client development for the office SELECT PROJECT EXPERIENCE Marriott Hotel and Time Share, Park City, Utah Slope stability issues resulted in using rock bolts to anchor the highly fractured and clay filled adversely dipping limestone to competent rock. This entailed evaluating the rock bolt spacing, length and angle of drilling. Mr. Schrenk provided quality control services during rock bolt installation and evaluation of the extent of installation.

Leisure World, Vista/Oceanside, California Geologic and geotechnical field studies involving rock rippability studies to evaluate the rock hardness, provided geologic qualitative analysis on slope stability, alluvium removals, sub-drain design information, grading plan review, and review project quality control during grading.

City of Lake Elsinore, California Principal geologist in the preparation of a comprehensive geologic hazard study text and map for the City of Lake Elsinore. Included in the study was the identification of potential areas of liquefaction, rock fall hazards, debris flow, fault hazard issues and areas of high groundwater.

University of California at Irvine Responsible for the geotechnical exploration and preparation of a comprehensive geotechnical report for the multi-story physical science building and several other major buildings on campus.

3.0 EXPERIENCE AND PROJECTS

Figure 1: Khatri International Inc. has designed numerous wind tower foundations for projects across the country. Our designs utilize various foundation systems, including spread footings, and foundation anchor systems. The foundation shown here is a sppread footing for a 500 kW turbine installed at a manufacturing plant in Illinois in October of 2009. A rock anchor type foundation was considered for this project, but the spread footing was determined to be the most economical solution.

Figure 2: We have worked in the wind tower industry designing wind towers for 10 years. These projects involve large scale steel tubular tower struc- tures worth $100 million per project. Our team develops structural designs, cost estimates, and works directly with construction teams to assure these towers are built in accordance to design plans and specifications. Following is a list of wind farms projects we have been involved with: Altamont , Patrick and Henderson, Inc.: Performed structural and foundation design for 80 meter towers mounted with NEG MICON Turbines for a 110 MW wind farm. Argonne Mesa Wind Project, Patrick and Henderson, Inc.: Performed struc- tural and foundation design for 69 meter tower mounted with a MHS 1 MW Turbine.
