North Dakota Wildlife Crossing Improves Highway Safety for Animals and People
To help reduce wildlife-vehicle collisions and protect North Dakota’s bighorn sheep population, a wildlife underpass was completed recently as part of a $38.5 million project along U.S. 85 that replaced the historic Long X Bridge over the Little Missouri River south of Watford City.

Increasing Profits and Winning More Work: GMF Industries’ Journey from Traditional to Model-Based Estimates
Estimating is inarguably one of the most-important and challenging aspects of any project, especially in today’s market in which the pressure is high to deliver competitive estimates in tight timeframes. At the same time, errors during takeoff, the volatility of material prices and complexities of predicting labor requirements increase the potential for risk. Traditional estimating processes, which have evolved from hand-written documents and spreadsheets to on-screen digitizing takeoff, can b...
A Rise in Urgency: Impacts of Rising Waters and Waves/Erosion on Great Lakes Infrastructure

The house literally rolled down the embankment to the rocks below as the shoreline on which it was built collapsed, sliding into Lake Michigan. The home was a complete loss, leaving the owner unsure if insurance will cover the costs. The h...
Mobile Technology Drives the Need to Change Heavy Civil Construction
SYNCHRO Field allows users to alert the team to an issue from the jobsite, automatically adding map coordinates and linking the project issue directly to the model view with a simple workflow. Heavy civil infrastructure projects are getting larger and more complex. As a result, more than 50 percent of projects fail to meet budget and schedule. Many factors drive such complexity, including the following: • No two projects are the same. Each project has its own set of circumstance...
Shoreline Stabilization: Teamwork and Technology Tackle a Growing Concern
