Experience - General

Self-employed engineer since 1978. Have worked in the planning, design and construction phases of a wide variety of projects. Examples include development of hydroelectric power plants, design of products made from renewable materials and permit coordinator for projects requiring federal licensing and state water quality and historic certification. Shorter term assignments have included structural analysis of steel and timber frames for bridges and buildings, lightweight design of wooden boat hulls and masts and design of concrete retaining walls.

Experience - Specific

Engineer of record for 8 hydroelectric projects, responsible for layout of plant and civil works and selection of hydraulic turbines and mechanical drive assemblies. Work included structural analysis of steel support frames and reinforced concrete design of building elements to national AISC and ACI code requirements. Did mechanical design of shafts and power transfer devices to ASME codes, in consideration of fatigue and other long life design standards. Selected bearings, gearboxes, sprockets, pulleys and belting to industry standards. Computed hydraulic capacities of penstocks, weirs, canals, tailraces and spillways.
On all projects, performed cash flow analysis that included revenue projections for differing turbine selection, annual operational costs, debt service and internal rates of return on equity.
Owners representative for FERC and state inspections.
Own and operate a 280 kW fully automated hydroelectric plant with automatic trash rack cleaner.

Designed and built computer control panels for automating operations at hydroelectric plants and industrial processing concerns. Components included Programmable Logic Controllers, analog input transducers, utility safety relays and numerous operator devices. All systems can be remotely sensed and dispatched. Wrote program instructions in ladder logic.

Supplier of PLC control panels for Hydro Turbine Systems Inc., the North and South American Representative of Ossberger Turbine.

Principal author of 6 successful FERC License applications.

Prepared plans and supervised subsequent construction for two privately owned dams. One utilized a timber frame spillway in an earth embankment dam, the other was a concrete gravity dam on bedrock foundation. Wrote emergency action plans.

Designed an energy absorbing packing material made from recycled newsprint which incorporated a thin shelled structural element with a high crushing strength. Was issued U.S. Patent No. 5,151,312. This new packaging medium seeks to replace styrofoam "packing peanuts".
