Construction Engineering Requirements for Integrating Laser Scanning Technology and Building Information Modeling

Laser scanning for rapid spatial data acquisition is an established technology in the architecture, engineering, and construction (AEC) sector with a wide range of applications. An understanding of the wide variation of technical requirements and considerations associated with these applications is critical to decision making about laser-scanning implementation on projects. Furthermore, significant industry transformations in the use of building information modeling present extraordinary opportunities for AEC professionals to employ the use of laser scanning in the context of holistic, collaborative workflows grounded in three-dimensional model-based design. This report analyzes the construction engineering requirements of laser scanning technology for applications across all phases of the project life cycle and proposes a multidisciplinary framework to integrate applications of laser scanning technology with the fundamentals of three-dimensional model-based design.

CD-ROM multimedia. The step before virtual reality

Applications developed using key multimedia elements are finding their way into a number of training and information exchange environments including the laparoscopy training market. Emerging multimedia-based applications range from procedural information for patients to interactive CD-ROM-based applications used to train highly skilled surgeons. These products are designed with a high level of interactivity that allows the surgeon to plan a surgical procedure, review detailed patient information and then merge that information into the surgical planning process. Using this new technology, a surgeon now has the ability to review CD-ROM-based course materials and efficiently meet continuing education requirements. The factor found most limiting in the development of multimedia-based applications for laparoscopy training is generally not the technology, but the limits placed on the technology because of one's reluctance to think beyond what is accepted as the norm. Properly implemented, multimedia applications developed for laparoscopy training reduce the cost and time associated with learning new materials, assist a user in retaining more of the information reviewed, and in many cases make the learning experience much more enjoyable.     

The Soldier Fitness Tracker: Global delivery of Comprehensive Soldier Fitness.

Carefully implemented technology strategies are vital to the success of large-scale initiatives such as the U.S. Army's Comprehensive Soldier Fitness (CSF) program. Achieving the U.S. Army's vision for CSF required a robust information technology platform that was scaled to millions of users and that leveraged the Internet to enable global reach. The platform needed to be agile, provide powerful real-time reporting, and have the capacity to quickly transform to meet emerging requirements. Existing organizational applications, such as “Single Sign-On,” and authoritative data sources were exploited to the maximum extent possible. Development of the “Soldier Fitness Tracker” is the most recent, and possibly the best, demonstration of the potential benefits possible when existing organizational capabilities are married to new, innovative applications. Combining the capabilities of the extant applications with the newly developed applications expedited development, eliminated redundant data collection, resulted in the exceeding of program objectives, and produced a comfortable experience for the end user, all in less than six months. This is a model for future technology integration. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
