BIM and Blockchain

In 2008, a seemingly modest proposal was made to make secure electronic cash transactions directly between interested parties. Called Bitcoin, it is now a worldwide phenomenon with the potential to disrupt money as we know it. But what exactly is Bitcoin and why should we in the AEC technology industry care about it?

In this article, Jim Forester, a long-time AEC technology veteran and enthusiast, attempts to shed some light on the underlying concepts of Bitcoin technology, Blockchain, and how it is immediately applicable to many aspects of built environment projects as well as the BIM technologies used to realize them.


Perspectives on Historic BIM Developments in Italy


In this article, Stefano Della Torre, Director of the Department of Architecture, Built Environment and Construction Engineering at the Politecnico di Milano in Italy and a specialist in the field of restoration, shares his insights on the application of traditional BIM tools, which are primarily geared for new construction, to the historic preservation of our built cultural heritage.


In Defense of Traditional 3D Laser Scanning


With rapid developments in 3D scanning technology over the past thirty years, reality capture is now faster and easier than ever, taking form in high definition terrestrial systems, aerial photogrammetry systems, handheld infrared systems, and everything in between. In this article, Tucker Cedarleaf of Cedar+Mac, who has been working with laser scanning equipment and software for over 10 years, debunks the assumptions many users make that all reality capture is equal and that it’s as simple as taking photographs. He shows how and why traditional laser scanning tied to survey control is the only method of 3D capture that produces baseline data of the quality and reliability required for AEC industry use.


How Mead & Hunt Marshals Resources to Improve Project Delivery

In this Viewpoint article, Andy Knauf, Vice President of IT at Mead & Hunt, a top-ranked architecture and engineering firm, describes how his firm searched for and subsequently found and implemented an effective solution that would enable its multi-state workforce ¬– more than 525 employees in 30 active offices as well as numerous job site offices – around the US to share and access files and project information quickly and easily for improved project delivery.


Delivering on the Promise of BIM

This Viewpoint article highlights the challenge of the project information explosion caused by the adoption of building information modeling (BIM) in the AEC industry and the importance of managing all this project information systematically to render order from chaos. When properly implemented, BIM is delivering tangible benefits to all project stakeholders, but AEC firms also need to adopt adjunct systems to manage BIM inputs and outputs in a way that helps them deliver on the promise of BIM.
