Capture data is post-processed to stitch the multiple scans (sometimes more than 3,000) into one point cloud. The most exciting factors being: scan data is true, trusted, and can be immediately applied with the utmost confidence (Figure 2). A well-trained scan tech and one scanner can capture more information in one day than a team of engineers could possibly capture in months, maybe years. Why send a team of engineers to a project site to “measure up” the situation? This has been common practice for many years, yet, this typically results in missed information, inaccurate dimensions, and a costly return trip. 3D models can be constructed to represent a complete facility, with the ability to zoom in to specific areas and calculate minute dimensions, if desired. Some of the steps required and benefits provided by reality capture follow.Ģ. Once goals are understood, the 3D reality capture team can get to work. Secondly, site, demo, lifting, safety, laydown, installation, and operation planning can be easily visualized and simulated as long as the proper areas and equipment are captured. Capturing and delivering valuable data initially allows for the exploration of concepts, scope development, and thorough requests for quotation. Assessing project goals, determining which data points are most important, and prioritizing goals should be a part of this conversation. Making certain the 3D reality capture provider is thoroughly informed is the first step in project risk reduction.

What does the workflow look like? It all starts with a conversation.

By supporting solid modeling of the point cloud, simulations, clash detection, overlays, drawings, software training, and workflow implementation, the client is equipped to focus on the project at hand and not saddled with self-education. Today’s top 3D reality capture suppliers understand the need for post-capture technical support for their clients. A lack of support from the 3D reality capture service provider left many early attempts to be viewed as failures. Those who tried 3D reality capture in its early days often received a point-cloud deliverable, which was not easily applied to common design applications. 3D Reality CaptureģD reality capture has been around for decades, but it has not been widely adopted due to factors such as availability, cost, delivery timelines, and a lack of understanding of the dynamic impact it can have in all phases of a retrofit project. At project conclusion, the final as-built documentation should be captured in 3D, as its uses extend far beyond simple diagrams.

Every major retrofit project should start with reality capture and leverage trusted data through each stage of project execution. Modern equipment and advanced workflows have provided a means to create these virtual worlds in a cost-effective and timely manner. This world can be created with 3D reality capture and delivered in point-cloud, photo-realistic (Figure 1), or solid-model formats. Imagine a world without a need for 2D drawings, in which all needed information was available ahead of time, in an accurate and easy-to-use format. The compressor shown here is one example of what can be displayed on a computer or web-enabled mobile device. 3D reality capture can produce detailed and interactive views in point-cloud, photo-realistic, or solid-model formats. 2D drawings can be hard to locate, harder to decipher, many times are not up to date, and often lead to more confusion than clarity.ġ. Pictures are nice, but often do not provide the needed vantage point and are typically useless for measuring. Social distancing brings the challenge of sharing necessary project information with disparate groups across the globe in a simple format. Further complicating matters, some companies are reluctant to let employees travel at all, making site visits impossible. The ability to bring various subject matter experts, vendors, contractors, and safety specialists onsite during a project’s conceptual and planning phases has become difficult due to social-distancing requirements. “Normal” has vanished and may not return, at least not in the near term. Over the course of a few weeks, the normal project execution process has shifted, as many companies set new guidelines limiting interpersonal contact during the COVID-19 pandemic. 3D reality capture offers a better, more-useful tool for owners. Standard general arrangement drawings, and piping and instrumentation diagrams, serve a purpose, but they are not ideal records for as-built project documentation.
