Site Investigations: A Guide (available in Geoenvironmental Special Issue only)
A geotechnical engineer looks at the evolution of reports on subsurface conditions, the most uncertain portion of construction. Most of the cost and risk of construction occurs beneath...
Nothing Wasted
Anoxic gas flotation (AGF), a patented system for anaerobic digestion of organic slurry waste, can recover as much as 85% of the phosphorus and 23% of the nitrogen in slurry waste, while...
Stretching a Landfill
Landfill expansions can pose engineering challenges, and the Tullytown, Pa., landfill gives an example of a horizontal expansion that added 121 acres of future disposal space. The side-by-side...
Preparing for Pier A
Earthquakes, oil wells, contamination and unstable soil were among the challenges engineers faced as they prepared a site at California's port of Long Beach for the Pier A...
Geotechnics of Industrial By-Products
Large volumes of industrial by-products are generated each year by U.S. industries, and most are landfilled as solid waste at considerable expense. However, many by-products have desirable...
Paper Mill Sludge Landfill Cover Construction
A considerable amount of experience has been acquired from a number of completed paper mill sludge landfill covers within the United States. This paper focuses on practical guidelines...
Recycled Materials for Embankment Construction
Obtaining good quality soils at reasonable costs for use in embankment construction is becoming difficult and hence, attention is directed towards finding alternative materials. On the...
The Safe Disposal of Fly Ash in Pavement or Earth Structures Not Requiring High Strength Materials
Highway agencies throughout the country face the challenge of safe disposal of various waste products in pavements and earth structures. Some of these waste products can be hazardous to...
Database on Beneficial Reuse of Foundry By-Products
This paper describes a database on beneficial reuse of foundry by-products that was assembled at the University of Wisconsin-Madison. The database was designed to identify (1) materials...
Quarry Conversion
All over the country, old landfills are filling rapidly, and potential new sites�and public support for them�are in short supply. Cities are faced with increasing solid waste disposal...
Higher Ground
Thirty floods over the course of a century, capped by three major floods in 1993, finally convinced residents of Pattonsburg, Mo., that it was time to move the entire town to higher ground....
Environmental Exposure
The increasing risk of environmental liability calls for engineers and contractors to include environmental risk management as part of a firm's business procedure, even if...
The Deep (Available in Geo-Environmental Special Issue only)
Despite a mere 1,500 ft separation, Baltimore's Oriole Park at Camden Yards and Ravens Stadium required vastly different deep foundation solutions. While Oriole Park is founded...
Crane Safety on Construction Sites
Net Gains
Project Web sites can be as simple as a repository for drawings and documents or complex enough to allow real-time dialogue between interested parties and project monitoring. One of GZA's...
Oil in the Soil
An oil well blowout in northern Italy contaminated about 1,500 ha of agricultural land primarily used to cultivate rice. The cleanup team decided to use bioremediation techniques because...
Brownfields by the Book
To spur the redevelopment of brownfield properties, many state legislatures have passed laws that allow developers to revitalize contaminated industrial sites without the high risks or...
Containing the Cold War's Hot Waste
A new method for the construction, verification, and maintenance of underground vaults isolates and contains radioactive burial sites without excavation or drilling in contaminated areas....
Dealing with DNAPLs
Trichloroethylene (TCE) in groundwater is one of the most prevalent contamination problems at hazardous waste sites; a problem that is substantially greater if the TCE is present as dense...
Building Between Buildings (Available in Structural Engineering Special Issue Only)
Construction of tall buildings in the centers of the world's large cities almost invariably involves working within severe site constraints. The constraints can involve all...
