A navigation network is required for analysis in several activities during various phases of a building lifecycle, such as building accessibility analysis [22], building egress code compliance ([15], [11]), wayfinding [10], indoor positioning [18] and navigation guidance [18]. Various models for representing navigation networks have been proposed in literature [1], such as graph-based, set-based and hybrid models, but there is lack of a standard representation for exchanging navigation network information. We have identified the information requirements for representing navigation networks in AEC domain, such as spatial connectivity, network distance and network geometry, to name a few. The identified requirements have been mapped to existing navigation network representations, such as graph-based, set-based and hybrid models, to create a lightweight representation of navigation networks in the Construction Operations Building Information exchange (COBie) schema [4]. Our developed lightweight representation is based on a hybrid model and involves extending the COBie schema with 'Node', 'Edge' and 'Node-Tree' tables and utilizing the existing 'Coordinate' table in the COBie schema. We conclude this paper with a discussion on the implementation of the proposed representation of navigation networks in the COBie schema.

A reference model for BIM capability assessments Yilmaz, Gokcen; Akçamete Güngör, Aslı; DEMİRÖRS, ONUR (2019-05-01) Various BIM capability and maturity models have been developed to assist architecture, engineering, construction and facilities management (AEC/FM) organizations in measuring the performance of their BIM utilizations. Due to differences in applicability and focus of these models, they are able to meet the demands of different BIM users. In this study, eight BIM capability and maturity models identified in the literature are compared based on several different criteria. The results show that there is no holi...
Cognitive routing protocol for disaster-inspired Internet of Things Ai-Turjman, Fadi (Elsevier BV, 2019-03-01) In this paper, we propose a framework for data delivery in large-scale networks for disaster management, where numerous wireless sensors are distributed over city traffic-infrastructures, shopping-malls' parking areas, airports' facilities, etc. In general, our framework caters for energy-efficient applications in the Internet of Things (IoT) where data is propagated via relays from diverse sensor-nodes towards a gateway connected to a large-scale network such as the Internet. We consider the entire network...
A study on tall buildings and aerodynamic modifications against wind excitation Ilgın, H. Emre; Günel, Mehmet Halis; Department of Architecture (2006) The purpose of this thesis is to create basic design guidance for tall buildings and their aerodynamic modifications as a resource for architects, engineers, developers, and students. It aims to make a contribution to and strengthen particularly the architect̕s understanding of tall building design, that requires a high level of interdisciplinary approach, by providing a broad overview of the أtall buildingؤ with its general concepts; to demonstrate the importance of human element as a critical component in...
A genetic algorithm for resource leveling of construction projects Iranagh, Mahdi Abbasi; Sönmez, Rifat (2012-01-01) Critical path method (CPM) is commonly used in scheduling of construction projects. However, CPM only considers the precedence relations between the activities and does not consider resource optimization during scheduling of projects. Optimal allocation of resources can be achieved by resource levelling. Resource levelling is crucial for effective use of construction resources particularly to minimize the project costs. However, commercial scheduling software has very limited capabilities for solving the re...
Models for estimating construction duration: an application for selected buildings on the metu campus Odabaşı, Elvan; Elias Özkan, Soofia Tahira; Restoration in Department of Architecture (2009) The duration of construction of a project depends on many factors, such as: cost, location, site characteristics, procurement methods, area of construction, footprint of the building and its height, etc. It is very important to be able to predict these durations accurately in order to successfully complete a project on time. Various construction duration estimation tools have been developed to make accurate predictions, as “time is money.” The main objective of this study was to develop a model that can be ...
