Tunnel and Bridge Construction with Minimum Disturbance to Overhead Services
The rapid growth of pipe jacking over the last 20 years and the improvement and development of methods in terms of lengths of drive, size and ability to work in varying ground conditions...
Infrastructure Project Management and the Power of Implementation
The purpose of this paper is to bring renewed attention to project management concepts and public policy implementation issues as they apply to infrastructure development and renewal....
Micros Go Afield
Taking microcomputers into the field is boosting productivity at construction sites and other field offices. Four examples presented in this article include an owner calculating payments...
Quality Control: A Neglected Factor
Quality in construction is too important to leave to chance. A project quality control plan would begin by incorporating testing and inspecting requirements into the specifications. Engineers...
The Pursuit of Quality: QA/QC
Quality assurance and quality control programs are mandated for many federally-funded construction projects. The private sector is also increasingly requiring such programs. The terms...
Design of Strontia Springs Arch Dam
The development of the layout and the history of design of the 292 foot (89 m) high Strontia Springs Dam is presented. While a brief description of the general project layout and foundation...
Geotechnical Aspects of Strontia Springs Arch Dam
The bedrock at the Strontia Springs damsite consists of generally excellent quality granitic and metamorphic rock, except for a wide shear zone located beneath the dam in the lower valley...
Construction of Strontia Springs Dam
Strontia Springs Dam is a principal feature of the Foothills Project on the South Platte River, 25 miles southwest of Denver, Colorado. The dam provides for storage and diversion of water...
Concrete Quality Control and Quality Assurance on Strontia Springs Dam
An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed...
Molikpaq Deployment at Tarsuit P-45
An overview is provided of the engineering considerations and approach to deployment of the Molikpaq. Topics addressed include site investigation, foundation preparation, berm construction,...
Overview of Artificial Island Design and Construction in the Arctic
An overview is provided of the design and construction of artificial islands in the Arctic. Since the early seventies more than 20 islands have been constructed in the Alaskan and Canadian...
Geotechnical Features of Fur Seal Island Design
In summer 1983, Texaco made plans to construct an artificial island in Harrison Bay of the Beaufort Sea to serve as a platform for exploratory drilling. Fur Seal Island is to be located...
Arctic Island Construction
The history of island building in the Beaufort Sea of Canada and the United States is reviewed. Construction methods are discussed. These include hauling material from onshore in both...
Modular Construction Technology for Arctic Islands
In order to investigate the possibilities for application in the Arctic of new generation construction vessels, a conceptual design of a production island retained by crane-installed concrete...
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
The Estimation of Ice Loads From Caisson Deformations Gulf Canada Molikpaq
The Gulf Canada Resources Mobile Arctic Caisson 'Molikpaq' is a bottom founded steel exploration platform capable of year-round operation in the Beaufort Sea....
Dynamic Global Forces on an Offshore Structure from Multi-Year Ice Floe Impacts
Estimation of global ice forces from ice floe impact against artificial islands and offshore platforms is essential for platform design. The discrete element program, CICE, has been validated...
Spatial Analysis of Ice Charts
Spatial approaches to ice environment modeling can not only lead to better local hazard predictions but also produce regionalizations that are useful for construction, navigation, and...
Probabilistic Approaches to Arctic Offshore Engineering
The arctic offshore environment poses challenges in design, site construction, and operation that range from the problems associated with large ice forces, to those of short open-water...
