Utilization of Waste Materials in Civil Engineering Construction
Industrial growth has increased the volume of wastes generated from energy production, mining, industrial processes and civil works. For economic and related reasons, the use of waste...
Boston's City within a City
The Massachusetts Water Resource Authority's 11-year effort to clean up Boston Harbor is in full swing. The nerve center of the project is Deer Island, a 210 acre site that...
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
Instrumenting the `Y'
Segmental bridges are still relatively new to the U.S. and questions persist about their design and behavior. To expand the knowledge base, a number of laboratory and field studies have...
Norway's Olympic Cavern
A mountainous task had been undertaken by Norwegian firms in constructing the world's largest in-mountain colosseum for the 1994 Winter Olympic Games in Norway. The Norwegian...
Put to the Test
In the construction industry, the concept of life-cycle cost applies not only to the infrastructure itself, but to the materials that go in to building that infrastructure. To improve...
Settling Down Easy
In order to more fully participate in the international and Asian Pacific aviation network, it was decided to establish a highly efficient 24-hour a day operation at the New Kansai International...
Underground Research: Here and There
Geotechnical research in Europe, Japan and the U.S. were compared in a study funded by the National Science Foundation. Visits to research facilities and several surveys resulted in two...
Rethinking the Competitive Bid
Concern that the U.S. construction industry is losing its competitive edge is nothing new. Ironically, the problem is not so much rooted in foreign technical expertise as it is in our...
Dome Over Orlando
The article describes Orlando's new City Hall, a 267,000 sq ft nine-story reinforced concrete tower, clad in granite-aggregate precast concrete panels and topped by a 120...
School Is In Session
Cost overruns, project delays and the city bureaucracy have given school construction a bad reputation throughout the U.S., particularly in urban centers. But as other construction markets...
Sending Steel Down the River
Completed last October 1990, the Roosevelt Lake Bridge is now the longest two-lane, single span, steel-arch bridge in North America, spanning 1,080 ft. Also, the longest steel arch bridge...
The Effect of Loading Rate on the Bending Strength of Alluvium Reinforced Ice
Traditional building materials are often less than ideal for construction in remote Arctic locations. Their mechanical properties may be degraded in extreme cold, and costs associated...
Sludge Dewatering in Freezing Beds
This paper summarizes the results of laboratory and pilot scale studies on the development of the sludge freezing bed. Laboratory studies indicated that a freezing bed could dewater up...
Winter Sewer Construction in Campbell Lake
This paper discusses the winter construction for replacement of the Campbell Lake portion of the Campbell Creek C-5 Trunk (C-5 Trunk) located in Anchorage, Alaska (see Figure 1). A previous...
New Admixtures for Cold Weather Concreting
Chemicals were tested for their ability to promote strength gain in portland cement concrete at low temperature. The admixtures depressed the freezing point of the mix water and accelerated...
High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...
Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...
Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...
Environment One: A Master Plan Study for a New Scientific Research Station at the Geographic South Pole
The existing research station at the geographic South Pole is approaching the end of its useful life. This master plan study focuses on determining the technical and functional requirements...
