How Backpack Mapping Transforms BIM Documentation


As every building construction professional knows, having accurate and timely documentation is key to ensuring that projects are completed on time and on budget. All too often, however, existing documentation is inaccurate, out of date or missing, and obtaining documentation during construction is time-consuming and complicated. This situation leads to guesswork and, ultimately, rework. Reality capture in the form of point clouds and imagery provides an attractive solution, but what’s the best way to capture reality indoors and out, as well as up and down stairs?

Video: Where BIM Is Taking Construction

Building information modeling (BIM) is having a substantial impact on the construction industry by improving accuracy and reducing risk. In this engaging panel discussion, we go behind the scenes with David Epps of Holder Construction, Russell Gibbs of Brasfield & Gorrie, and Chris Scanlon of DAVIS Construction to talk about some of the latest trends, including laser scanning, robotic total stations and multistations. Plus, Cathi Hayes of Leica Geosystems shares details about the latest innovation for data capture in building construction.

How Will SLAM Technology Revolutionize Building Construction?


SLAM stands for simultaneous localization and mapping. It was developed in the 1980s for robotics and has been used to guide self-driving cars and common household robotics such as the popular iRobot Roomba vacuum cleaner. Technically speaking, SLAM is a relative positioning concept based on sensor inputs such as photos or laser scans. It computationally creates a map of an unknown place while simultaneously tracking the location. The algorithms used depend on the sensor type, so different algorithms are used with photos than with laser scan data. So what does that have to do with building construction? Continue reading…

Basic MEP Field Tools for Enriching BIM Workflows

MEP layout

No matter where you are in your BIM adoption process – whether you are just getting started with digital layout or already using advanced 3D workflows on every jobsite – there are field tools that can enrich your workflows and help you improve your accuracy, efficiency and overall productivity. Most mechanical, electrical and plumbing contractors begin experimenting with BIM by using paper or CAD files for MEP digital layout. MEP layout requires accurate information throughout the entire process to avoid expensive rework, so having the ability to quickly and easily add construction layout points to your project is critical in the field, as well as in standalone CAD environments. Here are three common MEP workflow challenges and the basic field tools that can help you overcome them. 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

WOC promo_tcm45-615360

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.
