David has more than 26 years of broad practical experience in Electrical Engineering, and Project and Quality Assurance Management. Since 1998 he has been Vice President of Engineering for Timberline Engineering, Inc., with overall responsibility for project management and engineering production. Prior to that, he was a corporate Vice President and Manager of the Electrical/Mechanical Engineering Department for Leedshill-Herkenhoff, Inc., where he began his consulting engineering career in 1984. He has technical experience in all aspects of commercial, industrial, and utility-oriented electrical design. From his management and technical experiences he is capable of handling all phases of a project including project management, quality assurance management, field investigation, utility interface and coordination, development of design alternatives and life-cycle costs, schematic, preliminary, and final design, specification development, construction cost estimation, bid and field order review and negotiation, and construction management and observation.
Project Management Overview
David has managed all Timberline projects since 1998. Notable Supervisory Control and Data Acquisition (SCADA) projects include the $4.0 M County of Kauai, Hawaii Wastewater Management Division Island-Wide SCADA System, the $5.5M 86 RTU County of Kauai, Hawaii Department of Water SCADA System, $1.5M 38 RTU City of Milpitas, California Utility SCADA System, $2.5M 42 RTU Sweetwater Authority Water SCADA System Phase 1 and 2 projects in Chula Vista, California, and $1.2M 30 RTU Sangre de Cristo Water Company SCADA System Replacement (water system for the City of Santa Fe), Santa Fe, New Mexico. At Leedshill-Herkenhoff, Inc. David was Project Manager for three multi-million-dollar open-end contracts for the U.S. Department of Energy Los Alamos National Laboratory (LANL), U.S. Department of Energy Pantex Plant near Amarillo, Texas, and General Electric Aircraft Engine Plant in Albuquerque, New Mexico. For over five years David was responsible for the open-end design effort in Technical Area 54 (TA-54) at LANL. Under this assignment, he managed over 18 projects with total construction cost in excess of $20M. Particularly noteworthy was the TRU Waste Inspectable Storage Project for which LH developed construction documents for three closely related projects with a total construction cost in excess of $15M in less than six weeks. Prior to this assignment, he managed numerous multi-discipline projects under the Open-End Contract for General Plant Projects (1988-1991) with Mason and Hanger-Silas Mason Co., Inc. at the Pantex Plant. Under this contract David managed the design and construction services of approximately a dozen projects with a combined construction cost in excess of the $12M, including the $3.2M renovation of Pantex's sanitary sewer system. In addition, David managed a large study and design project to upgrade the emergency lighting and exit markings at the Pantex Plant, which involved 76 buildings at this highly secure site. Prior to this, David was Project Manager for several multi-discipline projects with construction costs totaling more than $8M during the modernization of the General Electric Aircraft Engine Plant in Albuquerque.
David's wide range of project experience enables him to offer electrical design expertise involving the following elements: primary voltage overhead and underground distribution systems; primary voltage switchgear including metal-clad and padmounted metering equipment and switchgear, step-down transformers, unit substations, and motor control equipment; building electrical systems including secondary power distribution, motor control, surge suppression and power conditioning systems, interior and exterior lighting, fire alarm systems, security alarm systems, public address, telephone and other communication related systems; Supervisory Control and Data Acquisition (SCADA) systems; instrumentation and control systems; lightning protection and ground counterpoise systems; prime power generation, cogeneration, and stand-by emergency generation and uninterupptible power supply systems; roadway and highmast area lighting systems; and airport airfield and security lighting. David has applied his technical expertise to the design of electrical systems associated with a wide variety of project types, including domestic and industrial water, wastewater, and stormwater utility systems including pump stations, wells, reservoirs, water treatment facilities, wastewater facilities and lift stations and stormwater lift stations; complex industrial building renovation projects; special electrical and control system projects; airports; and campus-type private electrical utility system projects.
