Moving beyond the fourth dimension with an IFC-based single project database

4D CAD has been an active research area for many years. The first generation 4D toots simulated construction schedules and demonstrated the potential benefits in several case studies. Researchers tried to improve the functionality of the first generation 4D tools by adding annotations and highlighting the building elements that have problems. The future generation 4D tools are expected to include more than these. It has been envisioned that 4D models would he part of project databases in order to take decisions related with different project dimensions.


Incremental transformation of spatial intelligence from smart systems to sensorial infrastructures
Erişen, Serdar (Informa UK Limited, 2020-01-01)
In addition to the scalability of new computation technologies considering their potentials and limitations, recent applications of embedded computation ensure its possible uses in the scope of urban computing and policymaking strategies. This study examines methods of crowdsourcing with the aim of incremental transformation of the built environment through the experimental exploration of the traditional infrastructure of the Spice Bazaar in Istanbul using a bottom-up research approach. Thus, this study can...
Improving sub-contractor selection process in construction projects: Web-based sub-contractor evaluation system (WEBSES)
Arslan, Gokhan; Kivrak, Serkan; Birgönül, Mustafa Talat; Dikmen Toker, İrem (Elsevier BV, 2008-05-01)
One of the most important phases in the construction industry (CI) is the bidding process. During the bidding process, selecting the most appropriate sub-contractors (SCs) for the relevant sub-works is highly critical for the overall project performance. In order to select the most appropriate SCs for the project and prepare the most realistic and accurate bid proposal, general contractors (GCs) have to know all financial, technical and general information about these SCs. Within this context, GCs should co...
An evolutionary approach for 3D architectural space layout design exploration
Gürsel Dino, İpek (Elsevier BV, 2016-09-01)
This work introduces Evolutionary Architectural Space layout Explorer (EASE), a design tool that facilitates the optimization of 3D space layouts. EASE addresses architectural design exploration and the need to attend to many alternatives simultaneously in layout design. For this, we use evolutionary optimization to find a balance between divergent exploration and convergent exploitation. EASE comprises a novel sub-heuristic that constructs valid spatial layouts, a mathematical framework to quantify the sat...
Toward a Multidimensional Performance Measure for International Joint Ventures in Construction
Ozorhon, Beliz; Arditi, David; Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2011-06-01)
Measuring the performance of joint ventures has been an important research topic for a few decades. No consensus on an appropriate definition and measurement of performance of international joint ventures (IJVs) has yet emerged, and the validity of the underlying measures is still questionable. In this study, the construct validity of measures that define IJV performance in construction is evaluated using data obtained through a questionnaire survey. A second-order performance construct is proposed, which i...
A smart contract system for security of payment of construction contracts
Ahmadisheykhsarmast, Salar; Sönmez, Rifat (Elsevier BV, 2020-12-01)
© 2020 Elsevier B.V.Timely payment of project participants is crucial for successful completion of construction projects, however the construction industry worldwide suffers from poor payment practices. The existing research studied the reasons and the consequences of the payment problem, but very few studies proposed methods for eliminating the problem. In this paper a novel smart contract payment security system named SMTSEC is presented for eliminating or reducing payment issues in the construction secto...
