Infrastructure Development and Turbine Building
Aggressive development schedules which characterize many projects imply a degree of construction management know-how or alternatively, may say something about the state of the industry...
Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...
Fishery Issues Slow Boardman River Redevelopment
At issue was the requirement of the Michigan Department of Natural Resources (MDNR) and the U. S. Fish and Wildlife Service to require the establishment of fish ladders at the hydro sites....
Importance of Public Consultation
Early consultation with governmental resource agencies as well as private environmental groups can mean the difference between early resolution of conflicts between developers and environmentalists...
Planning for Small-Scale Hydroelectric Development: A State Response
A 'surplus' of power in the Pacific Northwest region of the country has brought with it a declining interest in the generation of new electrical energy supplies....
Small Hydro Advocacy
The state public utilities commissions wield enormous power over the destiny of small hydro projects; power extending over rates, contract terms and dispute resolution. Yet developers...
Coordinating Engineering and Environmental Activities in Hydropower Development
This paper reviews the role of hydropower project personnel, particularly the interaction between project management, engineering, and environmental sciences staff in project planning...
Fish Screens for Hydropower Developments
The paper reviews five screening systems that are now being used at hydropower developments. The screen types discussed have a demonstrated ability to meet agency fish screening criteria....
Salmon Restoration: Blessing, Bane or Boondoggle?
The 'strategic' plans for the Atlantic Salmon Restoration Program were examined to determine what the strategy of the U. S. Fish and Wildlife Service is for this...
Hydropower Contract Conditions for Civil Engineering Works
Norwegian types of contract documents for hydropower construction work - especially the underground parts - have long had the reputation of being flexible as opposed to the traditionally...
Design and Construction of Paute Project, Ecuador
The Paute Project is a key element in Ecuador's program for developing a modern electric power system. When fully developed, it will consist of three separate developments:...
Efficient Small Hydroelectric Plant Operation
This paper presents a review of operating and maintenance alternatives for small scale hydroelectric plants. The cost of operating a hydro project is largely determined by decisions made...
Seismic Isolation System for a Floating Dry Dock
The seismic isolation system consists of two dolphins, each a relatively large-diameter cantilevered steel pipe pile anchored in Franciscan rock, and buffered connections to the floating...
Steel Poles?Past, Present and Future
When using steel pole structures, construction possibilities are limitless. Of all the options available, tubular steel structures provide the most versatility for transmission line construction....
Lattice Tower Design Using Cold-Formed Shapes
The use of cold-formed shapes in lieu of hot-rolled angles may lead to major changes in the design of lattice transmission towers. The design procedure of the new shapes is more creative,...
Cold-Formed Angles for Transmission Towers
Cold-formed members enable the engineer to design transmission towers that may be more cost-effective than those built with hot-rolled angles. Members can be designed to closely fit the...
Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...
Bolted Connections for Steel Towers
Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1)...
Strain Gaging and Data Acquisition at the TLMRF
Strain gages are the major source of data for the TLMRF (Transmission Line Mechanical Research Facility) research program. Measurement of member loads and bending moments in lattice towers...
Special Pile Foundations for a Coastal Permafrost Site
The design of the plant's foundations had to address several challenging geotechnical conditions. These included (1) 'warm' (close to 32 degree F)...
