Change orders present one of the largest sources of cost growth on building construction projects and have negative impact on productivity, labor efficiency and building environment. Building Information Modeling (BIM) is proved a high technology that greatly benefits both design and construction, greatly promoting the design visualization and construction 4-D modeling. Driven by BIM, Integrated Project Delivery (IPD) emphasizes communication in the collaborative process by avoiding adversarial or counter-productive professional relationships to reduce waste and rework. If BIM&IPD can be properly applied in project, quite a lot change orders can be avoided and then project cost will be reduced. This paper investigates the impact of BIM&IPD on construction change orders using Bayesian Network method. Bayesian Network is a graphic model representing cause and effect relationship between change orders and BIM&IPD. In this paper, evidence reasoning and probabilistic inference analyses are conducted to indicate the causes in light of the results and forecast the results according to causes. From the analysis, Bayesian Network is proved a good tool for construction managers to make decisions.

As the intricacy of construction projects is amassed, prospects for tribulations are mounting, depicting negative impact on projects’ cost, time and excellence. Thus, eliciting claims that aredisruptive to projects, time consuming and exorbitant. BIM holds enormousprobable in prosperous claim management practices. The progression of BIM can enrich knowledge sharing for information of a building or facility. It forms a vitalbase for decision making throughout the life cycle phase from the conceptual design to demolition. BIM is also, a valuable multidisciplinary cohesive source of information technology that posts benefits and disputes in the construction industry. The main aspiration of this paper is to appraise how and to what magnitude BIM can help evading and plummeting claims in Jordan construction industry.The paper ran a literature review on recent research, industry reports, and other sources to seehow they identified claims, its classifications, benefits, impacts and challenges of BIM on construction projects.Also, the paper acknowledgedcontemporaneous challenges in the claims field and the construction industry as whole. The attained outcomes have shown that BIM overtakes traditional claim management practices in many aspects including recognizing and investigating claims, where the benefits are comprehended in time and cost savings, less change orders, less rework. Moreover, the information and knowledge management that BIM postulates can improve many aspects of claim management.

Variation order (VO) is one of the main issues faced by the construction industry in Jordan. Many researchers had investigated on the causes of VO and proposed procedures to minimize and control this issue; however, the VO is affecting the construction industry badly even at moment. Building Information Modeling (BIM) is a powerful management system that can make a significant difference in the project costs. However, BIM has not been examined as a tool to minimize the VO in Jordan. The main target of this study is to utilize BIM applications in reducing the effect of VO on the governmental projects in Jordan. In order to achieve this target, the researcher has designed a questionnaire to gather data related to VO causes and the BIM capability to solve this problem. The data collected from the questionnaires were analyzed statistically. The result from the analysis found that the consultant initiated the highest VO of 50% followed by the clients and the contractors of 20% and 10% unforeseen variation respectively. Moreover, it is found that BIM Design Applications, Facility Operations Simulation, Exploration Design Scenarios, BIM Design Detection and BIM Quantity Take-off and Cost Estimation were significantly capable of minimizing VO. The results show positive relationship with the application of BIM in minimizing VO in the construction industry in Jordan. © 2018. JASET, International Scholars and Researchers Association

Digitalization is considered a dynamic change process powered by the rapid development of innovative concepts (e.g., building information modeling) that brings substantial potential benefits to the construction industry. However, previous studies of the benefits of digitalization (BIM) were mainly based on laboratory data rather than actual practices, which compromised the reliability of the results for construction practitioners. This study investigated the impact of digitalization in EPC construction projects by integrating descriptive statistics and survey-based exploratory factor analysis (SEFA). After a detailed review of related studies and meetings with experts, ten main variables and 14 unified variables were identified. The data on these variables were collected by questionnaire surveys and the extraction of information from project documentation. A total of 62 participants from 33 EPC construction projects responded to the questionnaire survey. The SEFA results indicated that digitalization can improve both the cost and time performance, with greater potential for improvement in time performance for EPC projects. In a scenario with limited digitalization implementation, this research could motivate future researchers to develop more applied research and guidelines to achieve best practices in the domain of the digitalization of construction projects.

<p><strong>Abstract.</strong> The implementation of Building Information Modelling (BIM) in each project, which is planned, have a design and construction stages. In the construction stage the objects are modelled by architects, engineers, and surveyors. Modelling process allowed to construct a BIM, which replaces two-dimensional (2D) building information into a three-dimensional (3D). Noticed that 3D BIM created by surveyors is not the same as 3D BIM, which is created by architects. Therefore, the purpose of this study is to identify the differences of the created 2D draftings made by 3D models between surveyors and architect’s. The surveyors make their model by using Unnamed Aerial Vehicle (UAV) system: Airborne Drone Data and Data photogrammetric processing technology. The 3D models accuracy is assessed by UAV images processing. The 3D information should be used to calculate façade geometry, volume, distances, contours, which are in the shadowed side of the house, and create 2D façade draftings. Traditionally, architects used 2D building’s façade draftings for pre-design in Construction Projects (CP). 3D architectural model is created by using structural 2D draftings created with Autodesk software. The architectural 3D model is more convenient for the general design and the visual view, it is easily to evaluate the impact of the changes that will be made. The 3D architectural model helps to finish a project at a low cost and also to evaluate the effect of the changes made. The 3D model from surveys measurements shows real view of an object (with deformations), meanwhile the 3D model from architects is a corrected image. Discrepancies between surveyors and architect’s 2D models made by 3D virtual reality (VR) are analysed in this article.</p>

Design changes by owners are common to many construction projects and can cause severe delays if owners do not consider that a change in one part of the project may cause a series of changes in other parts of that project. The impact of a changed component on other unchanged components is known as the “change ripple effect”. To efficiently manage design changes, the ripple effect should be quantified and impact evaluated. This paper presents a building information modeling (BIM)-based quantification model to quantify the ripple effect of owner-requested design changes. The developed model calculates the impact of design changes and their ripple effect on a project’s total duration. After analyzing the ripple effect over time, the model updates the project schedule accordingly. To demonstrate its usefulness and illustrate its essential features, the model is applied to a case study.

Purpose Prompt and effective responses to incompatibilities between as-designed and as-built drawings prevent cost and time overruns and material waste. This paper aims to provide an efficient framework to handle mismatches between these two models with the least negative impact on the whole project. Design/methodology/approach First, 11 most frequent mismatches were identified through questionnaires. Also, the respondents were asked to determine the mismatches’ roots and solutions and the impact of applying solutions on the whole project. Afterward, the process to present the optimum solution to one of these mismatches was modeled. After running the application programming interface developed in Navisworks software, decision-makers access a form, showing mismatches, their causes and solutions, as well as the solutions’ effect. To finalize the optimal solution, a platform was provided on whether to accept the system solution or to propose an alternative. Findings To empirically validate the reliability of the proposed framework, two projects were investigated. Two different approaches to dealing with the same mismatch occurred in these projects were compared in terms of time, cost and material required. The results showed that addressing the mismatches through the proposed framework can efficiently enhance time, cost and material consumption, in comparison with the traditional approach. Originality/value There is currently no building information modeling-based holistic framework for managing mismatches between as-designed and as-built drawings. The results of this research can help contractors to make the best decision, saving project resources, when setting about a mismatch during construction.

The construction sector is notable for its interdisciplinary knowledge and complex interactions between different parties and the sector has been gradually adopting new methodologies to improve work and collaboration practices, such as the case of Building Information Modeling (BIM). A protocol for a systematic review is proposed to evaluate the effectiveness of virtual reality techniques in the Architectural, Engineering, Construction and Operations sector. The search will be carried out in the reference databases for the field. One of the main outcomes of this study is to assess the effectiveness of virtual reality tools implemented in construction projects at the same time it will try to estimate the cost of the equipment and the implementation of the intervention and if any other mentioned cost might be related to risk reduction or better performance. This protocol is registered in PROSPERO under the code of PROSPERO CRD42018085845.


The variants of the division of the life cycle of a construction object at the stages adopted in the territory of the Russian Federation, as well as in other countries are considered. Particular attention is paid to the exemplary work plan – "RIBA plan of work", used in England. A feature of this document is its applicability in the information modeling of construction projects (Building information Modeling – BIM). The article presents a structural and logical scheme of the life cycle of a building object and a list of works that are performed using information modeling technology at various stages of the life cycle of the building. The place of information models in the process of determining the service life of the building is shown. On the basis of the considered sources of information, promising directions for the development of the life cycle management system of the construction object (Life Cycle Management) and the development of the regulatory framework in order to improve the use of information modeling in construction are given.
