No More Waiting for Points: CECO Concrete Construction Saves Time and Money with Robotic Total Stations

CECO Concrete Construction has been in the concrete industry for over 100 years. Founded in 1912, the leading concrete subcontractor has 18 offices nationwide and has worked on all kinds of projects, from parking garages and high-rise hotels to hospitals and sports stadiums. Its most recent project is the new Minnesota Vikings stadium. With projects of this size and scope, time is money and the more control a subcontractor has over the total process and schedule, the better.  Continue reading…

How Mallory Collier Drives BIM at Brasfield & Gorrie

Mallory Collier, the lead virtual design coordinator for Brasfield & Gorrie’s Nashville operations, has a long history with building information modeling. Collier’s experience with BIM goes all the way back to college, where she was a member of the first BIM competition team at Auburn University. “I did my thesis on BIM,” said Collier. “We had to take a project through the process from inception to finish. The technology was still fairly new then, so I learned some in the classroom and the rest was self-taught in the field.” Continue reading…

When to Use a Scanning Total Station vs. a Dedicated Laser Scanner

When is it best to use a scanning total station versus a dedicated laser scanner?

It’s a question we’re increasingly being asked by professionals who want to improve accuracy and reduce rework on their construction projects. In both new construction and renovations, the rich, complete data captured with a laser scanner provides the required information with the accuracy needed for as-built documentation and construction planning. But what type of laser scanner is the best fit for your needs?

Two Hot Trends to Watch at World of Concrete 2015

Exciting things are happening in the concrete industry, driven by the emerging requirements of owners and general contractors to incorporate intelligent 3D model based design into layout and construction to reduce costly rework and keep projects on schedule. The World of Concrete show in Las Vegas next month – one of the top shows in the industry – is projected to be the largest in six years with 1,300 exhibitors and over 630,000+ square feet of exhibition space. In addition to all of the newest products and equipment, building information modeling (BIM) – incorporating intelligent 3D design models into construction and layout, and utilizing high definition scanning before and during construction to compare as-built to as-designed – is a hot trend in the concrete industry that will get a lot of attention this year.

A Simple Way to Monitor Structural Health in Supertalls and Superslims

“Supertalls,” the category of buildings over 984 feet tall, and “superslims,” a term being applied to supertall buildings with very small footprints, are becoming increasingly common in modern cityscapes. Surprisingly, however, structural health monitoring of the sort that is often deployed on bridges and dams is not a routine part of supertall asset management. Part of this is complacency; the Empire State Building, after all, was completed in 1931 and is still standing tall at 1,454 feet (including antenna). And in fact, skyscraper and supertall performance over time has been impressive. It appears that architects, structural engineers, and contractors really do know how to build tall buildings in ways that stand up to the forces of weather and time. But this very success could be creating new risk factors as the relatively sudden expansion of supertall and superslim construction puts pressure on architects to push the envelope of construction technology.
