TL;DR: In this paper, a building material selection model based on fuzzy extended analytical hierarchy process (FEAHP) techniques is proposed to provide solutions for two major issues: assessment based on sustainability principles, and the process of prioritizing and assigning weights to relevant assessment criteria.

TL;DR: A framework for a novel safety management and visualization system (SMVS) that integrates building information modeling, location tracking, augmented reality (AR), and game technologies is proposed that has a great potential to improve the identification of field safety risks, increase the risk recognition capacity of workers, and enhance the real-time communication between construction manager and workers.

TL;DR: In this paper, the authors developed an accurate, essentially fully automated method for construction progress measurement using a 4D BIM in concert with 3D data obtained by remote-sensing technology.

TL;DR: In this article, the authors provide a state-of-the-art review of mainstream studies undertaken between 2005 and 2011 within the normative built environment literature, finding that a total of 120 articles were published within this period.

TL;DR: A conceptual framework that integrates BIM with augmented reality (AR) so as to enable the physical context of each construction activity or task to be visualized in real-time is proposed.

TL;DR: Technology and algorithms that have the potential in aiding the automated assessment of construction site equipment operations and are able to identify and track equipment activity- and safety-related information automatically for job site performance and layout decision making are presented.

TL;DR: In this paper, the authors focus on individual BIM competencies, the building blocks of organizational capability, and introduce several taxonomies and conceptual models to clarify how individual competencies may be filtered, classified, and aggregated into a seed competency inventory.

TL;DR: In this paper, real-time location tracking and three-dimensional immersive data visualization technologies are used in existing construction worker education and training environments for steel-erection tasks performed by ironworkers in an indoor training center.

TL;DR: Preliminary results on detection of standing workers, excavators and dump trucks with an average accuracy of 98.83%, 82.10%, and 84.88% respectively indicate the applicability of the proposed method for automated activity analysis of workers and equipment from single video cameras.

TL;DR: It is concluded that while it is possible to adapt the model to extract quantities according to existing specifications for manual-based measurements, the adjustments are not without its implications in other model applications such as visualization or drawings.

TL;DR: In this paper, a multi-factor hierarchical fuzzy comprehensive evaluation model is established to facilitate the evaluation of satisfaction in both single stakeholder group and overall infrastructure and construction (MIC) project stakeholders.

TL;DR: The main objective in this study is to establish a framework for automating the generation of construction schedules by using data stored in BIM to create construction tasks, computes activity durations using available activity production rates, applies sequencing rules, and finally outputs a schedule.

TL;DR: In this paper, a multi-mode resource-constrained discrete time-cost-resource optimization (MRC-DTCRO) model is presented to select starting time and the execution mode of each activity satisfying all the project constraints.

TL;DR: In this paper, a mobile Radio Frequency Identification (RFID) portal for checking the compliance of personnel wearing Personal Protective Equipment (PPE) at construction sites has been proposed to improve the logistics of the existing compliance checking process and provide users with timely feedback.

TL;DR: In this article, the authors present a methodology to assist design decisions regarding the building envelope shape considering its implications on energy performance, which involves a flexible design system to generate alternative envelope shape designs, with integrated energy simulation, to calculate the energy demand of each design.

TL;DR: The research described in this paper provides a taxonomy for patterns of deviations and sources of errors and demonstrates that it is possible to identify the source, magnitude, and nature of errors by analyzing the deviation patterns.
