Building Information Modeling (BIM) and Safety: Automatic Safety Checking of Construction Models and Schedules
TL;DR: The developed automated safety checking platform informs construction engineers and managers by reporting, why, where, when, and what safety measures are needed for preventing fall-related accidents before construction starts, the safety area reviewed is fall protection.

The value of integrating Scan-to-BIM and Scan-vs-BIM techniques for construction monitoring using laser scanning and BIM: The case of cylindrical MEP components
TL;DR: The research presented in this paper combines the Hough transform and “Scan-vs-BIM” systems in a unified approach for more robust automated comparison of as-built and as-planned cylindrical MEP works, thereby providing the basis for automated earned value tracking, automated percent-built-as-planned measures, and assistance for the delivery of as -built BIM models from as-designed ones.

BIM-based fall hazard identification and prevention in construction safety planning
Sijie Zhang,Kristiina Sulankivi,Markku Kiviniemi,Ilkka Romo,Charles M. Eastman,Jochen Teizer +5 more
TL;DR: In this article, an automated rule-checking framework that integrates safety into BIM effectively and provides practitioners with a method for detecting and preventing fall-related hazards is presented. But only limited automation in modeling and planning safety processes has been exploited so far.

Real-time resource location data collection and visualization technology for construction safety and activity monitoring applications
Tao Cheng,Jochen Teizer +1 more
TL;DR: The results demonstrate that important construction information related to both safety and activity in field operations can be automatically monitored and visualized in real-time, thus offering benefits such as increased situational awareness to workers, equipment operators, or decision makers anywhere on a construction project or from a remote location.

DV Based Positioning in Ad Hoc Networks
Dragos Niculescu,Badri Nath +1 more
TL;DR: This work is proposing APS – a localized, distributed, hop by hop positioning algorithm, that works as an extension of both distance vector routing and GPS positioning in order to provide approximate position for all nodes in a network where only a limited fraction of nodes have self positioning capability.

PicoRadio supports ad hoc ultra-low power wireless networking
TL;DR: The authors present a configurable architecture that enables these opportunities to be efficiently realized in silicon and believe that this energy-conscious system design and implementation methodology will lead to radio nodes that are two orders of magnitude more efficient than existing solutions.
