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 […]

Structural Implications of a Construction Shutdown

A construction project may be shut down for a variety of reasons, such as the loss of financing, stop-work orders, labor or supply disruptions or disasters. The duration of the shutdown can vary from days to years, depending on the circumstances. Some of the implications of a shutdown are obvious. There are considerations for security […]

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 […]

Site-Structural Engineering for the Urban Environment

Having projects in the urban environment representing a large proportion of my career experience, I am always a little surprised when I encounter design professionals and contractors who do not fully appreciate the challenges and constraints associated with building on urban sites. While a lot of design professionals, contractors and other stakeholders have urban project […]

Should You Have Your Geotechnical Report Peer Reviewed?

The foundation is one of the most critical components of any structure.  Poor foundation design and construction can impair the serviceability of the entire structure and put adjacent structures at risk for movement and damage. The concepts, design parameters and construction considerations for a structure’s foundation system are based on a geotechnical subsurface investigation and memorialized […]
