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...
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....
Strength Data Base for LRFD of Transmission Lines
Reliability-Based Load and Resistance Factor Design (LRFD) has been proposed as a desirable alternative or a complement to the National Electrical Safety Code (NESC) for the structural...
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)...
35-Year-Old Foundations, Thule Air Base, Greenland
In February 1951 the secret project 'Blue Jay' to construct the base began. Timber piling were used in the foundations of boilers, generators, and other heavy...
The CBR Test Applied to Processed and Compacted Snow
The processes used during the past two decades to improve the snow bear a modest resemblance to conventional flexible pavement construction, thus the field CBR (California Bearing Ratio)...
Design and Monitoring of an Ice Drill Pad
An ice pad was sucessfully designed and built to provide a suitable foundation for an exploratory drill rig in the National Petroleum Reserve of Alaska in early 1985. Design considerations...
Design of Modular Structures for the Arctic
Sohio's efforts to continue the production and initial processing oil from Prudhoe Bay, Alaska requires additional production enhancement equipment on the Alaskan North Slope...
Snow Load Design for Colorado Mountains
During the past decade, Colorado mountain construction has experienced a period of rapid growth. New ski resorts and other business developments have resulted in many new facilities. For...
Anchorage Taps Eklutna Lake for New Water Supply
The 170 million Eklutna Water Project will furnish water to Anchorage, Alaska by the summer of 1988. The project consists of an 8,500-foot long diversion tunnel, 6 miles of 54 to 60-inch...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...
Waterfront Stabilization Project, Kaktovik, Alaska
This paper discusses an innovative 384-foot treated-timber cribwall design utilized to control rapidly accelerating thermal erosion and establish a roadway along the bluff on the Beaufort...
Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...
Proposed Operation of an Expert System for Analyzing Construction Project Risks
The principal problem for the construction project manager is selecting the most effective response when project progress deviates undesirably from targeted objectives. Optimally, the...
Optimal Design of Continuous Prestressed Concrete Girders
Design of continuous prestressed concrete girders with possibility of parabolically varying depth in each span is formulated in the form of a mathematical programming problem. The design...
Interactive Design of Reinforced Concrete Foundations
A new, highly graphical foundation design program, FOUNDATION-3D, provides the designer with a variety of easy to use foundation design tools in a flexible interactive environment. It...
Rebuilding Mexico City
After the September 19, 1985 earthquake in Mexico City, officials had to cope with a massive volunteer effort to inspect damaged and destroyed structures. Over a thousand engineers, contractors,...
Can Your Design Be Built?
A constructibility review takes place in the concept stage, preferably before the project design is completed. The reviewers usually are contractors or project engineers who have a great...
Spanning Urban Obstacles
Extension of Pittsburgh's Crosstown Expressway is a � mile portion of a massive $500 million urban highway now under construction. The extension is a complex of five roadways...
