The development of roads and highways poses specific challenges for construction companies and for geotechnical engineering.
According to research by Mott MacDonald and Soil Mechanics, Ltd. in the UK, 75% of projects had cost overruns that were over 10% of the original contract price. They also found that geotechnical caused 50% of the total cost overruns. According to the same research, the most common geotechnical causes for cost overruns included seepage and groundwater, encountering materials different in classification from the predicted materials, and withdrawal and replacement of supplementary inappropriate materials.
Additionally, during the asset lifecycle, road failures can result from events like earthquakes, storms and floods, landslides, sinkholes, and extreme weather and temperatures.
This e-book looks at how Bentley geotechnical engineering applications apply to the geotechncial challenges for Roads and Highways.
