Augmented reality (AR) is a commonly used term when teams are looking to innovate workflows in the areas of construction, surveying, and utilities. It is important for these teams to understand how AR operates when planning to use this technology to assist with accomplishing everyday tasks. Trimble SiteVision is a user-friendly, AR system that can be used in various workflows to simplify data measurements and visualize models in the field. Wit...

Water system design and analysis can be costly, time consuming, and challenging for municipal agencies. The combination of CAD, GIS, simulation and analysis features needed to produce a useful model usually means bouncing between different technologies and platforms. Often, it's a marginal CAD-enabled platform that requires export to a GIS platform, or a limited bolt-on tool that is tied to a GIS platform, neither supporting the iterative need...

Many state and local public works agencies are planning to leverage the upcoming infrastructure package from Congress to tackle their growing list of infrastructure planning, maintenance, and rehabilitation needs. Planning for infrastructure development can be difficult when agencies are relying on single-purpose computer-aided design (CAD) systems that don't support a rapid, agile design workflows or today's remote collaboration needs. MicroS...

Main street, highway or freeway, designing, building, and maintaining roadways requires a team of skilled engineers. And with constant changes, tight deadlines, and budgets, the job isn't easy. Whether you're responsible for corridor, interchange, roundabout, sanitary or stormwater network design, or the design of subsurface utilities; Bentley's OpenRoads Designer is a versatile application with all the tools needed to deliver projects from st...

A historical timeline will be presented that describes the significant seepage-related failure case histories and how various technology developed for seepage analyses and evaluations, including potential failure modes. The history of seepage technology begins in the 1800's but accelerates in the early 1900's and through the late 1980's. Each critical milestone in the evolution of seepage technology will be identified along with key published...

The 1889 breach of the South Fork Dam, which caused the infamous “Johnstown Flood,” remains the deadliest dam failure in US history. The Commonwealth of Pennsylvania built the dam in the mid-1800s as part of a cross-state transportation network, and the dam’s design and construction met the contemporary standard of care. However, decades of neglect left the dam in disrepair until a group of Pittsburgh tycoons hastily rebuilt...
