Reducing Risk to Adjacent Properties from Underground Utility Construction

In populated areas, underground utilities are the lifeblood of the community. These utilities require periodic maintenance, expansions and replacement. Therefore, underground utility construction is common in cities, suburbs and rural villages alike. Most people notice underground utility construction because of the traffic problems they may cause. However, if you are familiar with geotechnical or geostructural […]

What’s Wrong with Your Monitoring Plan

Construction, particularly in the urban environment, often exposes nearby structures and facilities to hazards, some of which are difficult to predict precisely and manifest as the work progresses. Impacts of this nature are associated with excavations, tunneling and foundation construction methods, and often require monitoring of potentially impacted structures and facilities. A monitoring program may […]

Nonlinearity and the Foundation Engineer

One of the challenges of real-world engineering problems is the need to predict the behavior of a system which may be complex, dynamic, nonlinear and subject to uncertainty as to loading and response. Foundation problems are a good example of this. The behavior of a foundation is complex; it is a soil structure interaction problem […]

When to Use Soil-Structure Interaction for Excavation Support Design

When structural systems are used to retain in-situ soil during excavation, the resulting soil pressures are difficult to accurately predict. In addition to the uncertainty inherent to soil materials, and the inability to fully measure those properties, the pressures on an excavation support system or permanent foundation elements that similarly retain in-situ soil and any […]

Who is Scoping Your Geotechnical Services?

Most significant new constructions projects begin with a subsurface exploration. Part of the purpose of the subsurface exploration is to provide a basis for geotechnical engineering necessary to design the foundations, earthwork, pavement and utilities for the project. In addition, the subsurface exploration and geotechnical engineer’s interpretation of the conditions observed inform the construction contractor’s pricing and […]
