Answering the $64,000 Question: Geotechnical Risk in Design-Build Projects
Subsurface risk may well be the aspect of most construction projects that has the greatest potential impact on a project's success or failure. Even when a thorough geotechnical investigation is conducted...
The Rise of UAVs Signals a New Era in Geotechnics: Big Data in Geotechnics is Coming from Above
If you have been following the news, browsing the internet, or even gazing up in the sky, it is likely that you have seen an Unmanned Aerial Vehicle (UAV), also commonly known as Unmanned Aircraft System...
Post-Earthquake Reconnaissance Using Digital Imagery: A Bird's-Eye View
Over the last decade, remote sensing has played an increasing role in geotechnical earthquake reconnaissance through the use of satellite imagery, LIDAR, and unmanned aerial vehicles (UAVs). These techniques...
The 2010-2011 Canterbury, New Zealand, Earthquake Sequence: Impetus for Rethinking the Way We Evaluate and Mitigate Liquefaction
Liquefaction is a common cause of ground failure during earthquakes and is directly responsible for tremendous damage to infrastructure. Evidence of the impact of liquefaction includes failure of bridge...
Review of Climate Science for Engineering Practice
Weather and climate are a factor in civil engineering design and practice. Weather is defined as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure,...
