GENERAL BACKGROUND

Mr. Nickerson is President and Principal Geotechnical Engineer for RWG&A and, as such, is responsible for technical oversight and management of our geotechnical work. His substantial experience includes heavy civil construction projects for industrial and power generation facilities. Mr. Nickerson has also been the project geotechnical engineer for commercial, residential and municipal projects including low and high rise buildings, underground utilities, bridges and highways. He has also developed expertise in underpinning, construction dewateri­ng and temporary earth support.

Mr. Nickerson’s work experience includes a position in the engineering department of an electric utility company. He was the department’s geotechnical engineer and served as the project manager and technical coordinator on all sizes of projects at generating stations, transmission and distribution substations, and operations facilities. The company had fossil and hydro generating stations, as well as transmission and distribution systems. Mr. Nickerson received Electric Power Research Institute (EPRI) training on proprietary software for the analyses for high moment transmission tower foundations. While at the utility company, he served as project manager for hydrogeologic investigations at marine oil terminals and for the design and construction of an engineered wastewater disposal system at a fossil generating station.

Mr. Nickerson participated in preliminary engineering studies for a proposed fuel conversion to oil-emulsion which would have required scrubbers to reduce air-emissions and handling systems for limestone and gypsum. Mr. Nickerson was the utility company’s project coordinator for a Superfund site where he managed technical and administration efforts for the cleanup. He received a company award for his efforts, which resulted in $10’s of millions in cost savings.

Early in his career, Mr. Nickerson worked in the offshore oil industry. This work primarily involved geotechnical studies for design of production platform foundations. Foundations consisted of 4- to 6-foot diameter steel pipe piles. The governing design criteria was provided by the American Petroleum Institute (API).

His work experience includes, but is not limited to, the following:

        * Foundation Investigations Soil-Structure Interaction
        * Design and Construction of Piers Pile Analysis and Installation
        * Construction Dewatering Rock Slope Stabilization
        * Inspection and Remediation Evaluation of Embankment Dams Pressure Grouting
        * Rock/Concrete Dam Spillway Stabilization Vibration Analyses
        * Waterfront and Riverfront Developments Mat Foundation Design
