BIM 101: How to Prep Model Data for Field Layout

If your project is working with highly accurate models in the office, that’s a good start for BIM. In many cases, however, the model data isn’t being used directly in the field. At best, this information gap drives up project risks; at worst, it results in errors and delays that can derail the entire construction schedule and budget and potentially lead to litigation. Fortunately, these problems can be easily solved by enriching the model with construction layout points.

AU 2013 Highlights Considerable Growth Opportunities in BIM

If you didn’t register early for the numerous building information modeling (BIM) construction sessions at Autodesk University 2013, you were out of luck. It was a preliminary indicator of the prominence BIM in construction would play at this year’s educational software conference, which drew an estimated 9,000 attendees to Las Vegas—a 15 percent increase from 2012—and approximately 40,000-50,000 virtual attendees via the Web.

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…

BIM 101: Three Basic Tools for Digital Layout

Getting started with BIM and digital layout can seem like a monumental task if you don’t know where to start. The first step is understanding the “lay of the land” – what are the parts and pieces, and how do they fit into your business. From there, it is much easier to strategically choose a starting point that will yield the best return on the investment. Continue reading…

Digital Layout Saves Concrete Contractor $2,000 Per Week

Concrete construction footing crews typically lay out footings with tape measures and strings. Once this this process is completed, the layout begins. “It’s generally around this time when we’d find a mistake in excavation or some other problem,” says Craig Poortinga of Walrite LLC Colorado Foundation Contractors. “The guys would spend a good part of the day putting materials in the ground and the find out the footing wasn’t right so we wasted all that labor to get to that point. At $30 to $35 per hour pay plus insurance, etc., with a three- or four-person crew, it adds up quickly.” Continue reading…

How to Bridge the Gaps in BIM

For many construction contractors, building information modeling (BIM) is primarily an office tool that provides valuable insights before crews begin their work on the jobsite. From there, however, the model is often converted to a 2D drawing that is familiar but limited in the amount of data it can offer. Construction crews proceed the best they can with the information at hand, using plumb bobs and tape measures to complete the layout process. The real-time field data that is essential to a successful BIM process is lost through critical gaps that are generally accepted as the norm. Continue reading…

The ROI of Digital Layout

In early 2012, Frazier of Lancaster, Calif., became one of the first multistate concrete companies to adopt robotic total station technology for standard layout tasks

In early 2012, Frazier of Lancaster, Calif., became one of the first multistate concrete companies to adopt robotic total station technology for standard layout tasks. “It’s our policy to be progressive—we used laser screeds early on, for example,” explains Vice President of Concrete Mike Prascsak. “We make that part of our presentations and interviews when preparing bids. Now, when we explain that we’re using the same tools as surveyors to set out points, and that we can even reset lost points if needed, contractors are amazed.” Continue reading…

How to Make the Most of BIM in Construction

If your firm is using building information modeling (BIM), you already know the benefits it brings to the construction process and your clients’ management of their assets. But are you reaping the full advantages of BIM? Continue reading…
