Heavy Civil Construction Case Studies

There are no perfect designers, no perfect contractors, and no flawless site conditions. Mistakes happen, and construction failures can stem from design issues, construction methods, or other factors. The consequences of such failures can result in rework, and affect a project in many ways. Knowing what worked and what did not work provides the insight needed to prevent failures.

Do you know how compaction work?

Did you know that poor compaction and inadequate moisture control in embankment fill can result in settlement issues, triggering rework and delays during construction?

Did you know that unanticipated high groundwater levels during foundation excavation may require installation of extensive dewatering systems and redesign of excavation support?

What measures can you come up with to make sure that your vetting process is robust enough and avoid selecting a subcontractor that, unbeknownst to you, will likely file for bankruptcy in the middle of the project, halting work and requiring a costly rebid process?

Did you know that non-uniform compaction and poor temperature control during asphalt overlay can result in premature rutting of the asphalt overlay?

The case studies presented here are short and focused case studies. They are presented to show what can go wrong on a construction project, and illustrate problem-solving. A lot can go wrong on a project. In the construction industry some mistakes or negligence can indeed have serious and even devastating consequences, including being fatal, costly, or career-ending.

These case studies can be reviewed by individuals or through group discussion. The goal is to get you thinking of 1) their root cause, 2) how they could have been avoided, and 3) the practices that should be in place to ensure they do not happen on your project.

Pick from the list of case studies and evaluate the issues.
