Trimble Connect is a project collaboration platform built for construction industry. Project stakeholders can easily share, comment on, and manage the project documents, photos, drawings, and 3D models through the cloud across the design, build, and operate phases of a project. This information can be seamlessly accessed across Desktop, Web, or Mobile environments depending on a stakeholder’s role or tasks. Trimble Connect Mobile App is simple to use and specifically designed for professionals working in remote or field environments such as the construction job site manufacturing facilities, or in project meetings or presentations. It is designed for one click access to the specific information needed to complete tasks that have been organized by the back office using Trimble Connect for Web or Desktop. Project information and files can be stored locally in the mobile application for offline use where internet access isn’t always accessible. Any new Tasks, called ToDos, can be created or modified while offline, then synchronized to the cloud once reconnected to the internet. One key differentiating feature within Trimble Connect Mobile App is its high-performance 3D model viewer. Large complex detailed construction models created by a variety of different Building Information Modeling (BIM) applications in multiple formats (IFC, SKP, RVT, DWG, etc.) can be quickly loaded, overlaid, and easily navigated through in a simple intuitive touch based interface.

Proceq GPR Subsurface: Powerful sensors with radar beams for subsurface mapping applications. Intelligent software at your fingertips. The mission behind Proceq GPR Subsurface is simple: Scan the underground to provide a clear 3D image of what lies beneath, to detect and map the findings effortlessly and reliably, and to collaborate anywhere, anytime, for utility strike prevention, as-built map verification, structural investigations and various geophysical applications. The revolutionary Proceq GS series is the world’s most advanced subsurface mapping system, equipped with Stepped-Frequency Continuous-Wave (SFCW) technology and precise GNSS positioning. The true-ultrawideband antenna system and Swiss-made, optimized electronics deliver unparalleled resolution and penetration depth - at the same time. The magic starts once you connect the GS9000 or GS8000 wireless to your iPad and fire up the Proceq GPR Subsurface app. The carefully designed user interface increases your productivity by making measurements and analysis simple and intuitive; for example, by switching between top and sectional views with a simple gesture. A rich feature set brings advanced workflows on-site, so that you can get more things done while in the field. See the heatmap of the subsurface form in front of your eyes at the specified depth range, annotate your findings with precise geolocation, tags, photos, voice memos and comments in the logbook. Access and share them with colleagues anywhere, anytime, and export your measurements in one click, in the form of rich reports, the most common CAD/GIS mapping formats, or raw data for further processing, all over the cloud. Detect utility lines and label them accordingly to produce as-built maps, or digitize any other findings on the ground. Get an instant understanding of what is below your feet with the revolutionary Free Path 3D real-time visualization, or superimpose your area scans onto the real world with Augmented Reality - unique features in the industry.
