Barriers to integrating lean construction and integrated project delivery (IPD) on construction megaprojects towards the global integrated delivery (GID) in multinational organisations: lean IPD&GID transformative initiatives

PurposeThe architecture, engineering and construction (AEC) industry encounter substantial risks and challenges in its evolution towards sustainable development. International businesses, multinational AEC organisations, technical professionals, project and portfolio management organisations face global connectivity challenges between business units, especially during the outbreak of novel coronavirus pandemic, to manage construction megaprojects (CMPs). That raises the need to manage global connectivity as a main strategic goal of global organisations. This paper aims to investigate barriers to integrating lean construction (LC) practices and integrated project delivery (IPD) on CMPs towards the global integrated delivery (GID) transformative initiatives and develop future of work (FOW) global initiatives in contemporary multinational AEC organisations.Design/methodology/approachA two-stage quantitative and qualitative research approach is adopted. The qualitative research methodology consists of a literature review to appraise barriers to integrating LeanIPD&GID on CMPs. Barriers are arranged into six-factor clusters (FCs), with a conceptualisation of LeanIPD&GID, GID strategy placements and FOW global initiatives with multiple validations. This analysis also involved semi-structured interviews and focus group techniques. Stage two consisted of an empirical questionnaire survey that shaped the foundation of analysis and findings of 230 respondents from 23 countries with extensive cosmopolitan experience in the construction of megaprojects. The survey examined a set of 28 barriers to integrating LeanIPD&GID on CMPs resulting from a detailed analysis of extant literature after validation. Descriptive and inferential statistical tests were exploited for data analysis, percentage scoring analysis, principal component analysis (PCA) and eigenvalues were used to elaborate on clustered factors.FindingsThe research conceptualised LeanIPD&GID principles and proposed GID strategy placements for LeanIPD&GID transformative initiatives and FOW global initiatives. It concluded that the most significant barriers to integration of LeanIPD&GID on CMPs are “lack of mandatory building information modelling (BIM) and LC industry standards and regulations by governments”, “lack of involvement and support of governments”, “high costs of BIM software licenses”, “resistance of industry to change from traditional working practices” and “high initial investment in staff training costs of BIM”. PCA revealed the most significant FCs are “education and knowledge-related barriers”, “project objectives-related barriers” and “attitude-related barriers”. Awareness of BIM in the Middle East and North Africa (MENA) region is higher than LC and LC awareness is higher than IPD knowledge. Whilst BIM adoption in the MENA region is higher than LC; the second is still taking its first steps, whilst IPD has little implementation. LeanBIM is slightly integrated, whilst LeanIPD integration is almost not present.Originality/valueThe research findings, conclusion and recommendation and proposed GID strategy placements for LeanIPD&GID transformative initiatives to integrating LeanIPD&GID on CMPs. This will allow project key stakeholders to place emphasis on tackling LeanIPD&GID barriers identified in this research and commence GID strategies. The study has provided effective practical strategies for enhancing the integration of LeanIPD&GID transformative initiatives on CMPs.

Identification of Critical Success Factors (CSFs) of BIM Software Selection: A Combined Approach of FCM and Fuzzy DEMATEL

The architecture, engineering, and construction (AEC) industry has seen a significant rise in the adoption of Building Information Modeling (BIM) in the last few years. BIM software have launched with numerous robust capabilities and features to satisfy the ever-demanding needs of the AEC industry. Various factors are associated with the selection of BIM software depending on a company’s requirements and constraints. BIM software selection is a daunting process as most AEC industries are unaware of the factors to consider when making this important decision. This study focuses on identifying the critical success factors (CSFs) and their interrelationship for efficient BIM software selection. For this research, a questionnaire was developed and disseminated in two stages in India, the United States of America (U.S.A.), Germany, and the United Kingdom (U.K.). In the first stage, a total of twenty-six identified CSFs were analyzed with the factor comparison method (FCM) to identify the top fifteen CSFs. Subsequently, the identified top fifteen CSFs were further assessed by implementing Fuzzy DEMATEL to categorize them into cause-and-effect groups based on respective influence strength, depicted with a causal diagram. Out of fifteen CSFs, five and ten factors were grouped into the cause group and effect group for BIM software selection, respectively. The most important factors were identified as software functionality, BIM adoption strategies and processes, interoperability, staff competencies, BIM standards and regional regulations. The outcome of this research can help BIM user companies improve their BIM software selection framework and decision-making process during purchasing software.

Building Information Modeling for Bridges and Structures: Outcomes and Lessons Learned from the Steel Bridge Industry

The recent push to adopt building information modeling (BIM) for bridges and structures in the transportation industry has encountered major barriers owing to the lack of standardization. Unlike the building industry that has the National BIM Standard®–United States (NBIMS-US™) as a formal open platform standard and guide for the development of interoperable BIM software, the transportation industry does not currently have a similar open platform standard to enable the creation of interoperable BIM software to serve the needs of transportation stakeholders. The purpose of this paper is to present the findings of the research for one of the first use cases and development of data exchange requirements and model view definitions in adopting the open platform NBIMS-US applied to bridges and structures for the U.S. transportation industry. A subcommittee of the American Association of State Highway and Transportation Officials and the National Steel Bridge Alliance Steel Bridge Collaboration was formed to conduct a pilot study into the creation of information delivery manuals (IDMs) for steel bridges. This study served as pilot for the development of future IDMs in the transportation industry. As a result, the current IDM for Steel Bridge Detailing and Fabrication serves as the starting point of TPF-5(372) BIM for Bridges and Structures development of the Design to Fabrication model view definition. Finally, this study provided the outcomes and recommendations needed to expedite the development of IDMs for other use cases in the bridge and transportation industry.

Bridge Design and Analysis using BIM Software

In the Bridge project, design and analysis include two main components: preliminary design and detailed design, to integrate Building Information Modeling (BIM) in the design process of the Bridge. Firstly 3D modelling of the Bridge needs to be carried out, that means. It has transferred 2D drawing into 3D models. The BIM mainly focuses on modelling analysis, detection and feedback and design. Cantilever bridge construction is a step-by-step construction of a cantilever in segments and stitching them to segments previously casted by prestressing. When the cantilever segments are added to both sides of the pier, the bending moment in Bridge is negative & increases with the addition of each segment. While key blocks are added, the Bridge is converted from cantilever form to continuous form & the negative bending moment on the pier decreases. In this project, a bridge model of span 130 m has been designed and analysed in midas civil to observe the rate of change of Bending moment, reactions and deflections at different stages of construction in construction sequence and Service conditions.

Impact of Passive Energy Efficiency Measures on Cooling Energy Demand in an Architectural Campus Building in Karachi, Pakistan

Electric appliances for cooling and lighting are responsible for most of the increase in electricity consumption in Karachi, Pakistan. This study aims to investigate the impact of passive energy efficiency measures (PEEMs) on the potential reduction of indoor temperature and cooling energy demand of an architectural campus building (ACB) in Karachi, Pakistan. PEEMs focus on the building envelope’s design and construction, which is a key factor of influence on a building’s cooling energy demand. The existing architectural campus building was modeled using the building information modeling (BIM) software Autodesk Revit. Data related to the electricity consumption for cooling, building masses, occupancy conditions, utility bills, energy use intensity, as well as space types, were collected and analyzed to develop a virtual ACB model. The utility bill data were used to calibrate the DesignBuilder and EnergyPlus base case models of the existing ACB. The cooling energy demand was compared with different alternative building envelope compositions applied as PEEMs in the renovation of the existing exemplary ACB. Finally, cooling energy demand reduction potentials and the related potential electricity demand savings were determined. The quantification of the cooling energy demand facilitates the definition of the building’s electricity consumption benchmarks for cooling with specific technologies.

From the result analysis of the structure, an approach is provided to repair the Bridge using BIM. As per IRC: SP -40 (Guidelines for techniques for strengthening and rehabilitation of bridges). This paper is an attempt to build a model that could demonstrate the use of BIM for bridge rehabilitation.

The Use of BIM Technology in Analyzing Building Energy and EconomicFeasibility of Solar Panel

Buildings contribute more than 40% of world energy consumption, so it is feared that it will cause energy problems in thefuture, especially in the construction sector. One solution to reducing this problem is by analyzing energy use at the initialdesign stage and utilizing solar energy as one of the solar power plants (PLTS) in office buildings. To analyze the use ofenergy in buildings, Building Information Modeling (BIM) was used. The purpose of this research is to analyze the annualenergy level of office buildings in Palembang using BIM software, namely Autodesk Revit. The number of solar panels aswell as the amount of energy were also identified using web-based software (HelioScope) resulting the economic feasibilityas indicated by the installation of solar panels as a component of PV mini-grid. The results showed that the use of BIMtechnology in analyzing building energy can provide a detailed description of the building model at the design stage. Revitanalysis indicates that the building consumed electrical energy per year for about 3,647,713 kWh with a roof area of 1,657m2. In addition, based on the HelioScope analysis, the use of renewable energy from the installation of PLTS was 152,900kWh/year. Meanwhile, for economic feasibility analysis, the installation of PLTS in office buildings can provide a positive NetPresent Value (NPV), indicating a feasible project.

Building-Information-Modeling Based Approach to Simulate Strategic Location of Shelter in Place and Its Strengthening Method.

It is important to consider establishing a shelter in place (SIP) using existing facilities to prepare for unpredictable and no-notice disasters. In this study, we evaluate the building-information-modeling (BIM)-based approach to simulate the strategic location of SIP and its strengthening method. BIM software was used to model a light rail station and analyze the elements of the facility that can affect the evacuation time to reach the SIP. The purpose of this study was to understand the effects of structural standards on the design of SIPs using a direct simulation. The differences between domestic and overseas standards were analyzed. An analysis was carried out to evaluate whether national specifications are satisfactory. As the proposed evacuation method is based on a rational human behavior analysis through a direct simulation, it was going to be a safer and faster route of evacuation in the case of physical terror attack situations for existing infrastructure, Furthermore, the SIP design is considered where reinforcement of the SIP structure is necessary. Three types of reinforcing were considered. Here, the use of high-strength, high-ductility concrete proved to be an effective method to improve the impact resistance of reinforced concrete walls and recommended for strengthening reinforced concrete members.

A proposal of a 3D segmentation tool for HBIM management

There are several studies related to the cultural heritage digitization through HBIM (Heritage Building Information Modelling) techniques. Today, BIM (Building Information Modelling) software cannot represent old buildings with complex prominent and particularly detailed architecture perfectly, and multiple software are combined to obtain the buildings’ representation. In this paper, in order to find an alternative way of replicating the complex details present in antique buildings, a new methodology is presented. The methodology is based on a process of direct insertion of various 3D model parts (.obj), into a BIM environment. These 3D model elements, coming from the points cloud segmentation (from UAV and Laser Scanner), are transformed in intelligent objects and interconnected to form the smart model. The methodology allows to represent detail of the objects that make up an element of cultural heritage, although not standardizable in shape. Although this methodology allows to ensure a perfect reconstruction and digital preservation and to represent the different “defects” that represent and make unique a particular object of cultural heritage, it is not however fast compared with the traditional phases of point cloud tracing and more software are necessary for data processing. The proposed methodology was tested on two specific structures’ reconstruction in Reggio Calabria (South Italy): the Sant’Antonio Abate church and the Vitrioli’s portal.

The creation of 3D building models using laser-scanning data for BIM modelling

The digital 3D models of the buildings based on laser-scanning data become a vital source of data and information repository to the Architecture, Construction, Engineering and Facilities Management (AEC & FM) sectors. A major advantage of the points cloud data captured by laser-scanning technology is its ability to the representation of the details of the three-dimensional models to exemplify the as-is conditions of buildings. However, the creation process of 3D models from the dense coloured 3D points provided by laser scanners has a significant impact on the quality of that produced models including building edges, walls, doors and windows. In particular, much uncertainty still exists about the compatibilities between the points cloud data formats and software extensions for the creation of as-is Building Information Modelling (BIM) models of the buildings. This paper presents a new framework for the creation of a 3D building model by transferring laser-scanning data into BIM software, such as Autodesk Revit. In our framework, an adopted link between software extensions was established in creating an accurate 3D building model. This framework is a road map of the required steps for investing the points cloud data relevant to BIM modelling. The promising results of the new approach illustrate to extract the 3D models of the buildings can reduce time-consuming, cost and efforts in dealing with or transferring laser-scanning data into Autodesk Revit for BIM models.

The Revolution of Quantity Surveying Profession in Building Information Modelling (BIM) Era: The Malaysian Perspective

Building Information Modelling (BIM) has becoming the current trend in the construction industry where quantity surveying serves as important discipline. Undeniably, BIM adoption has brought many advantages due to automation of multidimensional model platform that helps Quantity Surveyors (QS) to reduce arithmetic errors and removes many tedious tasks in conventional approach such as tendering and the production of bills of quantities (BQ). BIM will soon replace the traditional measurement done by QS if the Standard Method of Measurements (SMM) could be integrated in BIM. As a result, it is concerning that unemployment of quantity surveyors might be an issue if there is no revolution or adaptation of quantity surveying practices with the blossoming of BIM implementation in Malaysia. Hence, this research is carried out to determine the new skills needed by a quantity surveyor in order to keep pace with the implementation of BIM in Malaysia. Qualitative research method is used in this study in which semi-structured interview was carried out with 20 experienced QS that applies BIM technology in their practices. Data abstracted from the transcript of interviews was then coded though NVivo 12 Pro and analyzed by using content analysis method. At the end of the study, the findings revealed that the QS must attain IT skills and BIM software knowledge to align with BIM drive. It is thus recommended that thorough provisions of integrating traditional methods of quantifying and costing building projects with cutting edge technologies must be included in BIM standard to ensure that BIM can be adopted at its best in the profession with increase performance.

Building Information Modeling approach to optimize energy efficiency in educational buildings

The high amount of energy consumption demanded by buildings entails the worsening of several environmental issues. Therefore, actions to make use of this resource more efficient become necessary. The most used methods of Building Energy Modeling (BEM) designated to assess the functionality of such actions are excessively complex and, in many cases, generate unreliable results. Thus, this work aims to elaborate an approach based on Building Information Modeling (BIM) to improve energy efficiency in buildings in a simplified and user-oriented manner. For this purpose, a case study was developed in which two classrooms of an educational building, located in the Amazon region – Brazil, were subjected to three-dimensional modeling and energy simulations in BIM software. In addition to evaluating the classrooms’ current performance regarding daylight, thermal conditions and energy consumption, such simulations intended to assess the implantation of two strategies that sought to reduce energy consumption and maintain thermal and visual comfort by taking advantage of daylight and natural ventilation. Besides of energy saving, such strategies were chosen as they promote Indoor Environmental Quality (IEQ) and help to mitigate the indoor transmission of infectious agents, which is fundamental due to the COVID-19 pandemic scenario, especially in educational environments. The results showed that the strategy based on daylight contribution generated energy savings of around 8% for one of the rooms, and 12% for the other, while the one that exploited the use of natural ventilation was able to reduce energy consumption by about 7% for one of the rooms, and 9% for the other. Therefore, this research presents an important contribution as it provides an intelligible workflow that makes the energy simulation process friendlier and more intuitive and that was able to generate plausible results using BIM-BEM interoperability.

Dynamic thermal simulation based on building information modeling: A review

With the emergence of the fourth industrial revolution and extensive promotion of information communication tools, it is on the construction industry to reconsider the current linear design approach and adopt more integrated design approaches that encompass dynamic thermal simulation. Building information modeling (BIM), without a doubt, is a technology, which proposes an integrated practice for building design. Design team using BIM cooperatively work on each activity loop during the design procedure and present a three-dimensional (3D) design model with all data from various disciplines attached at the final stage. The inclusion of a data-rich 3D shape into the design procedure marks the dynamic thermal simulation as a simple, accessible, and, more importantly, decisive stage. This article aims to draw the role of BIM in facilitating the inclusion of dynamic thermal simulation in building design procedures. BIM in this article is introduced as an effective remedy for dealing with the linear nature of conventional building design that is the major impediment to the inclusion of dynamic thermal simulations in the design efforts. This article goes through the conventional method's deficiencies and challenges with the BIM-based method to portray each approach's advantages and disadvantages. Renowned BIM software, interoperable simulation tools, and their distinguishing characteristics are introduced in summary to give a better insight into the application of BIM for dynamic thermal simulation purposes. Additionally, a literature survey on applying the introduced tools is conducted to derive the possible BIM-based mechanisms for thermal performance and comfort analysis. This article concludes that, regardless of interoperability issues, BIM by coordination of building data and information in a consistent framework significantly facilitates data collection procedure for conducting dynamic thermal simulations. In combination with data collection and interoperable simulation tools, BIM tools provide novel mechanisms for dynamic thermal performance and comfort analysis. Highlights Traditional and BIM-based building design procedures have been reviewed. The role of iterative simulation in BIM-based simulation has been elaborated. A BIM-based framework for building design has been provided. BIM-based approaches for thermal performance and comfort analysis have been reviewed.

Development of a Semiautomatic Parametric Method for Creation of an I-BIM Model of a Tunnel for Use in FEM Software

This paper focuses on the design phase of I-BIM tunnelling projects using Sequential Excavation Method (SEM), in Europe, commonly referred to as the New Austrian Tunnelling Method (NATM), and addresses the problem of coupling geotechnical conditions and tunnelling Building Information Model (BIM) for the preparation of the computational model suitable for the finite element analysis method (FEM). The review of the literature led to the conclusion that an automatic merging of the tunnel model and ground model for use in the FEM software is currently not reliable due to the number of differences between various types of models as they serve contrasting needs. Consequently, modelling becomes a manual task, which is very time-consuming and error prone. In this paper, we present the development of a framework for the semiautomatic transformation of the various tunnelling models and respective ground models into the model suitable for further analysis. We conclude that the import and translation of the geometry into the FEM software are most successful and accurate when the initial I- BIM (tunnel) model is prepared at a level of detail appropriate for a computational model. The result is the I-BIM model, fit for use in the FEM software which speeds up the modelling process and reduces errors. We have shown that it is possible to prepare the geometry of a tunnel in the BIM software, transfer it, and use it in the software for geotechnical analysis. This makes the preparation of the tunnel geometry for FEM analysis much easier and faster. Due to the fast preparation of the geometry of the new model, the approach presented in this research is useful in practice. The applicability of the framework and the framework workflow are both presented through a practical case study.

Building Information Modelling and Energy Simulation for Architecture Design

Over the years, building information modelling (BIM) has undergone a significant increase, both in terms of functions and use. This tool can almost completely manage the entire process of design, construction, and management of a building internally. However, it is not able to fully integrate the functions and especially the information needed to conduct a complex energy analysis. Indeed, even if the energy analysis has been integrated into the BIM environment, it still fails to make the most of all the potential offered by building information modelling. The main goals of this study are the analysis of the interaction between BIM and energy simulation, through a review of the main existing commercial tools (available and user-friendly), and the identification and the application of a methodology in a BIM environment by using Graphisoft’s BIM software Archicad and the plug-in for dynamic energy simulation EcoDesigner STAR. The application on a case study gave the possibility to explore the advantages and the limits of these commercial tools and, consequently, to provide some possible improvements. The results of the analysis, satisfactory from a quantitative and qualitative point of view, validated the methodology proposed in this study and highlighted some limitations of the tools used, in particular for the aspects concerning the personalization of heating systems.
