Automated Position and Control Systems Using Lasers and Electromagnetic Signals
Positioning is a crucial area in the successful integration of CAD data into the construction process. This paper looks at several areas of positioning using lasers and electromagnetic...
Discussion of the Use of Multi-Design Contracts
The paper begins by defining the multi-prime contract for design services, under which there is more than one contract between design professional and owner for a single project. It then...
Decision Support System for Achieving and Measuring Design Effectiveness
A microcomputer program is developed to serve as a decision system for improving design effectiveness. The program, called 'Design Effectiveness Evaluation and Implementation...
The Jet Set
The new maintenance hangar now nearing completion at Charlotte/Douglas International Airport has aluminum standing seam roofing. The unusual material was specified because every ounce...
Building Onto History
In a single design/build/renovation project, an Oklahoma City AE firm acquired new offices, provided new life for an abandoned historic church building and spearheaded redevelopment of...
The Great Quake: On Site Reports
Written within two weeks of the Oct. 17, 1989 California earthquake, these comments cannot be considered definitive. But they do stress two points: 1) Earthquake codes do work. Buildings...
Bells Under Bells
Chicago's newest office tower is supported on new bells that had to be constructed below existing belled caissons. Existing caisson foundations from a previous structure on...
Roller Compacted Concrete II
This volume includes the papers presented at the 1988 ASCE Specialty Conference on Roller Compacted Concrete. Included in the proceedings are experiences of roller compacted concrete dam...
Microcad: Pushing the Limits
Several engineering projects are covered which illustrate the increasingly complex design applications being accomplished with microcomputer based software. A dam, an apartment complex,...
Rehabilitation of Existing Hydro, Our Oldest Natural Resource
With renewed interest in hydro, many old sites are being rehabilitated to achieve maximum power output and higher efficiencies. Rehabilitated plants are now performing at optimal levels,...
The Uses of CADD in Hydropower Development
The hydropower community needs inexpensive methods to thoroughly and quickly analyze the siting of hydroelectric projects. Computer-aided design and drafting (CADD) and programs like HYSIZE...
Non-Federal Hydropower Development at Federal Facilities from the Project Developer's Perspective
The City of Santa Clara Electric Department has three small hydroelectric projects in various stages of development at federally-owned facilities. Although all three of the Federal Energy...
Development of Turbine Intake Downstream Migrant Diversion Screen
Prior to the spring of 1986 Public Utility District No. 2 of Grant County had developed a passive turbine intake screen design. A prototype of this design was placed in the emergency gate...
Protection of Juvenile Anadromous Fish
Protection of juvenile anadromous fish (salmon, steelhead, etc. ) during their seaward migration is a major concern in the Pacific Northwest. The existing screening structures at the head...
Hydrologic Studies for Dinkey Creek Hydro-Electric Project
The economic analysis and final design of the 120 MW hydro-electric development on Dinkey Creek, a tributary of the North Fork of the Kings River in the Central Valley of California, requires...
A Case for Selecting Only Deterministic Spillway Design Floods for High Hazard Dams
The Federal Energy Regulatory Commission has under license or exemption from licensing more than 2000 hydroelectric dams. The Office of Hydropower Licensing published, in September 1986,...
Cedar Falls Project-Rehabilitation with RCC
This paper presents an overview of the planning, design, and construction considerations used during the development of the 9. 1 m (30-foot-high) Cedar Falls Roller Compacted Concrete...
Performance of Draft Tubes for Small-Hydropower Turbines
Tests of several conical and elbow-type draft tubes were conducted with varying degrees of upstream swirl. This swirl was generated by variable-geometry vanes. Draft tube efficiencies...
Marginal Small Hydro Can be Made Viable
This paper presents the design and construction aspects of a 1,235 kW small hydro power development, comprising a new dam, gated spillway, intake canal, intake, penstock, tunnel, in-ground...
Improving Design of Small Hydro Plants
One objective of this paper is to show why certain features of many small hydro plants have given poor operational performance or experienced expensive maintenance problems. A second objective...
