Redpoint Positioning Integrates Real-Time Location With Autodesk's BIM Applications

Redpoint Positioning Corp., a developer of a GPS-like indoor positioning solution for construction safety and efficiency applications, has announced a demonstration of its integration with Autodesk's Building Information Modeling (BIM) solution—the Autodesk Forge Platform—enabling context-aware documents while improving construction job site efficiency and safety. BIM is a 3D model-based process that architecture, engineering and construction professionals can use to more efficiently plan, design, construct and manage buildings and infrastructure.

Redpoint's system monitors the real-time activity of assets and personnel on job sites with 8-inch location accuracy, and makes that information available through the Autodesk Forge Platform. According to Redpoint, the company is an early adopter of the Autodesk Forge Platform, which consists of a set of Autodesk cloud services, application programming interfaces (APIs) and software-development kits (SDKs)s for developers to quickly create the data, apps, experiences and services that power the future of making things. Redpoint leverages Forge APIs to monitor and record live construction job site activities inside BIM 360.

Launched in 2015, the Redpoint Indoor GPS solution is designed to improve industrial worker efficiency and safety by generating real-time data regarding work crews, tools and asset locations across job sites. Suitable for areas in which Wi-Fi networks are not always available, and where highly granular location data is required, Redpoint's patent-pending solution includes SafetyNet, a battery-powered infrastructure, along with wireless asset tags and wearable worker safety badges. The firm is targeting general availability for the commercial version of its technology during the fall of 2016, and is now engaged in pilot projects with several leading general contractors nationwide, including Skanska USA (see Redpoint Positioning Launches High-Precision RTLS).

Redpoint has reported that its solution is designed to provide the accuracy of an ultra-wideband (UWB) system at a more affordable price compared with those of other high-precision real-time location system (RTLS) solutions. It uses DecaWave's DW1000 chips, which comply with the IEEE 802.15.4-2011 (UWB PHY) standard, and Redpoint has also developed and patented software solutions to provide, for instance, the MAC layer, TDOA schemes and positioning algorithms. Using the DW1000 chip in conjunction with Redpoint's own software and tag components enables 2-D location accuracy of 20 centimeters (7.9 inches) and 3-D location accuracy of 30 centimeters (11.8 inches), according to the company. Redpoint also incorporates Bluetooth and other wireless technologies into its RTLS solution. The battery-powered tags made with DW1000 chips can act as transceivers, the company explains, and can be set up to create a wireless sensor network (WSN) and RTLS solutions. The tags come with embedded positioning algorithms, while network anchors, also made with the same DecaWave chips, act as satellites that make the Redpoint solution operate like GPS.

"Autodesk cares deeply about the safety of construction workers on project sites, so we support a future that includes context-aware mobile applications and data with that priority in mind," said Jim Lynch, Autodesk's VP, in a statement. "We look forward to working with Redpoint to location-enable many of Autodesk's applications and documents through the Forge Platform extending the value of project data across the construction process."
