A BIM-Based Coordination Support System for Emergency Response

Department of Architectural Engineering, The Pennsylvania State University

Abstract: In fire emergencies, timely communication with on-site coordinators and accurate localization of first responders facilitates effective task assignment and resource allocation in harsh, low-visibility environments. Building information modeling (BIM) is widely accepted in the architecture, engineering, and construction industries as a central repository of building information. It could provide both the geometric building data and semantic information; however, the convenient linkage and integration with indoor location technologies for emergency purposes have not been addressed according to the authors’ knowledge.

A stand-alone BIM-based indoor location (BIMIL) framework and portal were designed and tested to enable the automatic extraction, transformation, and visualization of BIM-related data for public safety purposes in this study. Based on current information technology, this research reduces the gap in cross-application by supporting indoor location to overcome the primary shortcoming of existing indoor building models. Eliminating the need for specific software and skill in data processing, this portal will support on-site coordinators’ importation of BIM files, allowing them to convert those files into processed and visualized indoor information containing key yet simplified geometric building data and essential emergency-related information such as fire rating hours, egresses, and hazardous materials. Additionally, the indoor location data can be integrated into a generalized 3D building model to support decision-making activities and management tasks in the field.

The “Worldwide Swarthmore Radio Network” is Swarthmore College’s official campus radio station. It broadcasts out of the suburban Philadelphia borough of Swarthmore, Pennsylvania.

Prior to the 1970s, WSRN operated as a carrier signal broadcast to the campus of Swarthmore College only. The station went on the air with 10 watts on October 15, 1972. Following efforts by the Federal Communications Commission to encourage as many Class D stations as possible to increase power, a campaign was raised by the students of the college, and in the late 1970s, the FCC granted a license for a 110-watt, directional, transmission.

Programming has been eclectic from the 1970s on. Station programming is diverse; music spans “world,” hip hop, blues, folk, rock, pop, R & B, and classical. Talk and comedy programs comprise much of the weekend line-up. Notably “Funk” which ran from fall 2012 to spring 2014 Friday mornings from midnight to 2AM.

In 1986, the main on-air studio was completely refurbished, with a new control panel, turntables, microphones, and wiring installed. 1998 saw the rewiring and modernization of the production studio and the construction of an acoustically isolated sound studio connected to the production studio.

Students have always manned the soundboard, and so, during most summers, the station is dark. Following the COVID-19 pandemic, the radio station had periods of limited broadcasting. During the 2021-2022 academic year, a significant effort by students, faculty, staff, and community members was successfully carried out to get the station back up to an operational state. As of April 1, 2022, the station has resumed broadcasting.
