SiteMap®, powered by GPRS, is a unique, shareable, multi-user collaboration tool that allows facility managers, project managers, architects, engineers, general contractors, and more to instantly see, share, and keep everyone on the same page on any jobsite in the U.S., from any desktop, laptop, or mobile device. This geospatial solution utilizes state-of-the-art GIS mapping, as well as industry-leading features that allow you to geolocate, tag, and share everything from underground utilities, pipelines, and storage tanks, through as-builts of existing buildings and infrastructure, to 3D BIM Models for prefabrication, design, and renovation purposes: all securely stored and cross-referenced by job and location within SiteMap®. The Digital Plan Room allows users to digitally file and cross-reference every drawing, as-built, map, utility locate, design, and specification for any facility or jobsite, or multiple sites across the U.S. There are multiple ways to access your jobs within the platform. You can directly access any job from the Jobs List to view and share. Jobs also populate the Map Viewer for quick reference and sharing. Click on a map pin for your job to see its thumbnail information. Click the thumbnail to share or view the job. From there you can choose among various menu features – from layers to features to groups – so that you can customize your view, or choose from the menu to be taken inside the Digital Plan Room for more information. Safety & Security are our #1 concern, so SiteMap® allows the subscriber to designate viewing access to only those they choose. Those permissions can be altered or revoked at any time by the subscriber, so you know your facility data is all in one place, secured by SiteMap® technology. Platform users and those they designate can view permissioned files in a secure and digitized manner by Visualizing The Built World™ to collaborate among teams and eliminate miscommunication, mistakes, cost overruns, delays, and injury. What can SiteMap® help you visualize?
