Non-Destructive Excavating Around Pipelines and Challenging Conditions
Hydrovac technology provides engineers and contractors with a unique solution for non-destructive excavating around sensitive buried lines. As a non-mechanical excavating method, it is...

Fluid Flows and Reactive Chemical Transport in Variably Saturated Subsurface Media

Jet Grouting for Microtunneling and Shaft Construction in Highly Congested Utility Corridors

Probabilistic Simplified and Detailed Subsurface Drainage Water Quality Modeling of Nitrate Leaching
A transparent uncertainty structure is derived for simplified and detailed conceptual nitrate leaching as a result of a probabilistic modelling procedure. The uncertainty structure consists...

Rediscovering the Lost City
Since 1994, Kenneth R. Wright, P.E., of Wright Water Engineers, in Denver, has been studying evidence of civil engineering at the ruins of Machu Picchu—an ancient Inca city in the Andes...

Tied by Water
Water utilities in the Puget Sound region of Washington State face strict water quality standards and increasing water demands. Because of the Endangered Species Act, they are also under...

Team Development Through Feedback
Groups and teams need to be effective in whatever they're doing; they need to achieve their mission or purpose. Just as important, every team or group needs to be seen as...

Overcoming Separation in Time or Space
Groups such as project teams, practice networks, and marketing groups are becoming ever more dispersed and distributed. For example, on a current project for a major water utility, I'm...

Subsurface Information for Construction Contracts - Impacts on the Geoprofessional Community

Safety in a Designer's Hands
Although contractors face safety issues every day, engineers and architects have traditionally not addressed construction site safety in project designs. But there are design practices...

Beach Town Cleanup
The Avila Beach remediation project in California required the demolition of numerous structures and part of the beach in order to remove more than 200,000 cu yd (153,000 m³) of contaminated...

Subirrigation: Water Table Management
Water table management (subirrigation) is accomplished by controlling the water table, usually through a subsurface drainage system. The crop is subirrigated with water being furnished...

Pipe Up
The East Bay Municipal Utility District (EBMUD) provides potable water for approximately 1.2 million people in San Francisco's East Bay area and is constructing seismic upgrades...

Betting on the Baseline (Available in Geoenvironmental Special Issue only)
In construction contracts, new deductive differing site conditions (DSC) clauses provide for credits to owners when contractors encounter better-than-anticipated subsurface conditions....

Microtunneling under Honolulu
Highly congested urban utility corridors present some of the most difficult conditions for construction of new underground pipelines, especially when subsurface conditions are also very...
