BIM 101: The Basics of Back Checking for Quality Assurance

If you are already taking your layout points out of the office and into the field, that is a major accomplishment and one that positions you for success using BIM in the field. However, it’s always best to “measure twice and cut once,” as the adage goes, so now is the perfect time for some important quality assurance (QA) steps. Continue reading…

Boston BIMForum Highlights Easy BIM As-Builting Solutions

At the Spring BIMForum in Boston, facility managers, contractors, architects and other building information modeling (BIM) professionals will be able to see firsthand an easy way to capture interior as-built information. The first Rapid Fire Technology Demonstration on Wednesday, April 23, will feature Fahim Dangra, national BIM sales manager for Leica Geosystems, who will show how the inexpensive and easy-to-use Leica DISTO handheld laser measurement tools tie directly into Autodesk Revit to provide a “BIM on the Fly” solution for interior as-builting.

BIM 101: An Easy Handheld Solution for As-Builting into Revit

BIM 101 for as-builting with Revit

For companies that are just getting started in building information modeling (BIM), the variety of hardware and software that is used to connect the real world with the digital world can seem intimidating. However, BIM doesn’t have to be complex. Leica Geosystems’ BIM Business Manager Cathi Hayes demonstrates how the Leica DISTO D330i, an inexpensive and easy-to-use handheld laser measurement tool, ties directly into Autodesk Revit to provide a “BIM on the Fly” solution for as-builting. Watch the video to learn more.

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.

If your BIM data has already been prepped for field layout, you’re ready for the next step: taking it into the field. Armed with BIM layout points, plan underlays and reference models, you are now ready to shoot points on the jobsite that replicate the accuracy of BIM in the office. Continue reading…

BIM 101: How Total Station Layout Benefits Construction Contractors

Total stations enable contractors to measure angles and distances extremely accurately for laying out new construction and as-builting existing construction using discrete points. Available in both manual and robotic options, they use a solid well-proven technology that originated in distance measurement applications for the military. They have been used in surveying and engineering applications for many years. Now, these same instruments and technologies are being adapted for the construction industry. Continue reading…
