Published: February 2022

Abstract
The planned relocation of the Indonesian capital city to East Kalimantan can lead to an increase in fuel consumption in the area, and to meet all these needs, a pipeline is planned to be built, to transport oil from the Balikpapan BBM Terminal to Samarinda and Palaran. The pipeline system is used for fluid transfer processes that are prone to damage where there are several potential hazards to pipelines and high costs for construction and maintenance, so it takes a lot of consideration in choosing the path to be built and risk assessment of the selected path. This study aims to select an alternative oil distribution pipeline, then identify hazards, analyze frequency, consequences, then represent risks and analyze mitigation efforts in overcoming the damage to the oil distribution pipeline. On alternative pipeline selection, the Analytical Network Process method is used. Alternative 5 was chosen, with combines of segment 1A (onshore), toll segment, Palaran segment, and Samarinda C segment. Then, for risk assessment, Kent Muhlbauer’s model indexing method is used, and based on the results of risk representation by looking at the average relative risk score, which is 19 points when flowing gasoline, and 41 points when flowing gasoil, it is found that segments 3, 4, 2B, 1B, 1D, and 2A are the most vulnerable segments with a relative score below the average. After carrying out risk mitigation actions, it’s found that the segments that are in a vulnerable condition exceed the average value of the previous relative risk score.

Abstract
East Kalimantan will be designated as the Ibu Kota Negara (IKN) of Indonesia. Energy consumption is predicted to increase, but based on Badan Perencanaan Pembangunan Nasional (Bappenas), fuel consumption will slowly be converted to gas. Previously, the process of fulfilling fuel needs in East Kalimantan was fulfilled using tankers, but with the issue of IKN, the government will build oil pipe Balikpapan – Samarinda that distribute fuel from TBBM Tanjung Batu to TBBM Samarinda and TBBM Palaran This research is for determine which scenario are efficient to distribute the fuel using forecasting methods with trend analysis, exponential smoothing, and moving average, while Powersim Studio 8 software is used for system dynamics modelling. With the help of this application, 6 alternative scenarios are made based on the tank capacity of each TBBM to find out the least amount of pigging. From the simulation, it was found that the second alternative is the most efficient for the process of distributing fuel. Where the results of the simulation process obtained pigging of 58 times/year with the capacity of gasoil TBBM Palaran 10000 kl, gasoil TBBM Samarinda 12306 kl and the gasoline is 14562 kl.

Published: February 2022

Abstract
Bricklaying has been one of the determinant technologies of the construction industry for several thousand years. Even in our modern times, it is one of the most commonly used fields of building construction technologies. There are several reasons, like the lack of human resources on the construction markets or the increasing demands on both reasonably short construction time and high construction quality, the combination of which leads to consideration of applying innovative, automated technologies in more and more fields. With the spread of these advanced techniques, changes and further development on the construction site can be predicted. One of these developing fields will be presumably the field of small, solid construction units, the innovation of which would result in changes regarding the elements and the technology too. In our research, automated bricklaying construction situations are modeled by applying a robotic arm equipped with a linear rail. Some new features are analyzed at the work of using automated systems. Namely, different brick wall construction methods are tested, measured, and analyzed to find optimal solutions for the cases of various sets of influencing factors, like element placement or palette arrangement.
Tracking and Monitoring Technologies to Support Airport Construction Safety
Authors: Hubbard B J , Hubbard S M 
Published: February 2022

Abstract
This paper discusses how advanced tracking and monitoring technologies can be used to increase safety for construction activities at airports. Airport construction is a significant infrastructure sector and in 2020 the Airport Improvement Program funded $300 million for airport projects in the United States. This includes funding for pavement reconstruction, airfield upgrades to meet current standards (e.g., wider runways), the construction of new terminal facilities, and additional capacity (e.g., new runways). The airfield environment presents special hazards for constructors, including proximity to active aircraft operations, and the requirement to comply with many additional rules such as those required by Federal Aviation Administration (FAA) and the Transportation Security Agency (TSA); many of these rules are required to ensure safety and security. Airport construction activities require close oversight, additional inspections by airport operations personnel, and stringent rules regarding access and operation in different areas of the airfield. Access and operating requirements affect both construction workers and construction equipment, and there are often different rules for different areas at the airport. One of the most restricted areas on an airport is the runway. Access to the runway and the safety area around a runway requires explicit permission from Air Traffic Control (ATC). If a vehicle or pedestrian (or aircraft) crosses the boundary without permission, it is considered a runway incursion. A runway incursion could cause a major incident at the airport and could result in injuries and fatalities. Runway incursion events are recorded by the FAA and represent a serious safety violation for the airport. Runway incursions and the technology to prevent incursions are discussed as an example that illustrates the need for and benefits of accurate monitoring of construction equipment and personnel. Technologies that may be used to enhance tracking and support situational awareness are present to illustrate the possible ways that enhanced monitoring can be used at an airport. Solutions may include the use of advanced technologies such as real-time vehicle location sensors, which may be combined with robust electronic maps to enhance safety for construction equipment and personnel location in the airfield environment. A discussion of opportunities and challenges of these systems is detailed.
An artificial neural network analysis of the satisfaction of hospital building maintenance services
Authors: Olanrewaju AL , Tan W X 
Published: February 2022

Abstract
Modern hospital buildings are very large, complex, sophisticated, and costly structures. The productivity of the hospital building users is influenced by the building performance. Maintenance services are conducted on the buildings to ensure optimum building performance and users’ satisfaction. However, many instances, have been recorded dissatisfactions among the hospital building users with respect to the performance of the maintenance services. This research investigated the satisfaction of private hospital building users with respect to maintenance services through a survey questionnaire that included ten satisfaction of maintenance services. The data revealed that the users are most satisfied with the standard of workmanship, cleanliness of the maintained area, communication with users during maintenance works, and degree of politeness and kindness of the maintenance workers. Using the nine/ten as the independent variables, an artificial neural network model to predict the satisfaction of users with maintenance services was presented. The model revealed that cleanliness and tidiness of the maintained area and the quality of maintenance works are the main predictors of the total maintenance service delivery of the maintenance organisations.
Configuring BIM models to Support A Systems-Driven Visualization Approach: A Case Study
Authors: Ensafi M , Harode A , Thabet W 
Published: February 2022

Abstract
Models developed through design and construction are not intended to support facility management. They don’t generally have the life-cycle data and information required or they are not configured to support visualization of model graphics from a system’s perspective. Current implementations for BIM-FM focuses mainly on including facility life cycle data in BIM models to support space management or asset management. Models are not customized with necessary data and classification that allow for isolating and visualizing components of a specific building system (e.g. supply air). This is necessary in an emergency situation to allow facility staff to diagnose the problem associated with the system and its components, identify the problem and make necessary and informed actions. In this paper, we discuss requirements for preparing an as-built BIM model to be systems-centric using a case study approach of a two-story science building. A system classification hierarchy was developed to classify the systems and sub-systems of the building. Sixteen systems-centric properties were defined to search, filter, isolate, and display elements in a specific system or sub-system. The configured systems-centric model will allow facility managers understand the dependencies across different systems to accurately determine impacts across the facility and develop strategies to rapidly respond to any emergency. The case study analysed the mechanical and plumbing systems in the building. This paper will focus on results from the analysis of the mechanical system. An example of emergency scenario is discussed and presented.
Process modelling for managing digitalised information exchanges in construction inspections and quality checks

Published: February 2022

Abstract
Processes of the Architecture, Engineering and Construction (AEC) industry are known to be characterised by a high level of complexity in terms of activities and involved actors, which requires a consistent exchange of information through each phase of a project life cycle. A digital transition applied to information modelling and management may support the optimisation of such processes. To overcome the traditional paper-based and document-centric approach, the so-called Common Data Environment (CDE) has been introduced and its adoption through the project life cycle is now regulated by ISO 19650. A CDE is a platform, whose purpose is to collect, manage and disseminate sets of information through a managed, interoperable and collaborative process. The fullest adoption of CDEs requires a methodological change towards data-based information exchanges. As a preliminary step to such a goal, the formalisation of procedures by process mapping and modelling can allow a more coherent management of use cases and related information exchanges. With a focus on the construction stage, the formalisation of inspection procedures is proposed through the Business Process Model and Notation (BPMN 2.0) format. Quality checks are taken into account in relation to the supply and installation of an External Thermal Insulation Composite System (ETICS). Quality control inspections and related activities are analysed and discussed within the framework of public works. An open source BPMN modeller and its workflow engine have been adopted. The result is a process model that (1) represents the complexity of managing information exchanges in such a scenario; (2) can be used as a basis for the development of a CDE where all the information is shared and accessible to the various actors of the construction process; (3) automatically feed, as a future work, an inspection management support system.
Impact of Environmental Sustainability on the Market Value of Office Buildings
Authors: Kupec J , Eklová K , Prostejovská Z 
Published: February 2022

Abstract
The issue of environmental sustainability of buildings is relatively new in many areas and has not yet been sufficiently explored. One of the little-explored areas is the relationship between environmental sustainability and the properties’ market value. In practice, LEED or BREEAM sustainability certificates are often used to determine the degree of environmental sustainability. These certificates are well known to international investors and tenants in domestic markets. Sustainability has evolved into a competitive factor due to its positive economic, ecological and social impact. Certified buildings are preferred by major corporate tenants with an international field of activity who often have ethical rules for sustainable development. This increases the attractiveness of the building, which has a positive effect on its market value.

Authors: Arar A J , Poirier E 
Published: February 2022

Abstract
Questions around integration, innovation, and collaboration within project teams have been the focus of increasing research in recent years. This is in response to the notorious fragmentation and the inherent performance issues that face the construction industry. Among the solutions identified, new contractual approaches, namely, integrated project delivery (IPD), have been investigated to understand how they can help overcome the industry’s issues. This paper aims to contribute to the previous efforts that studied the research trends of the IPD from 2001 to 2016 by synthesizing the last four years from 2017 to 2020. This period accounts for more than 70% of research on IPD compared to the previous 16 years combined. A systematic literature review was conducted to understand the trends in IPD research over the last four years. The results allowed the research team to understand better where such research was being conducted, what type of projects were being studied, and most importantly, the topics being covered within this research and its results. This paper proposes an initial review that will be further developed in a full-length journal paper.

Authors: Tian Y , Minchin R E , Chung K , Woo J , Adriaens P 
Published: February 2022

Abstract
Infrastructure development is a key to supporting the economy and building social resilience. Unfortunately, existing infrastructure financing models struggle with multiple issues to close the widening financial gap and integrate environmental, social, and governance (ESG) factors to improve resilience and achieve sustainable growth. With the emergence of innovative technology, blockchain-enabled asset tokenization shows the potential to create a new economic model to integrate non-financial values, such as positive social and environmental impacts, into tradable cryptographic tokens. Tokenization offers opportunities to generate long-term positive social and environmental impacts, along with better financial returns, which further improves the profitability and bankability of infrastructure projects. SolarCoin, WePower Token, and ZiyenCoin are analyzed in this exploratory case study research to demonstrate how blockchain-enabled asset tokenization can be applied to infrastructure development. It is identified that tokenization promotes inclusiveness and sustainability through shareholder empowerment, incentive monetization, and finance optimization. Obstacles hindering the broader adoption of tokenization and policy implications are also discussed.
Greenhouse Gas Emissions of Global Construction Industries
Authors: Crawford Robert H. 
Published: February 2022

Abstract
The global construction industry is responsible for considerable effects on the environment and society. The construction and use of our built environment accounts for 39% of global greenhouse gas emissions. Population growth and rising standards of living are further exacerbating these problems. Understanding the contribution of construction industries and those activities responsible for the greatest share of greenhouse gas emissions is crucial in order to identify opportunities for emissions mitigation. This study uses multi-regional input-output analysis to analyse the embodied greenhouse gas emissions of global construction industries. A structural path analysis (SPA) was conducted for the construction sectors of 44 countries using top-down economic input-output data from EXIOBASE3. The findings were analysed to compare the embodied greenhouse gas emissions of each construction sector to ascertain their emissions intensity. The structural path analysis was used to disaggregate each sector into unique nodes or pathways, with each representing a single or group of activities and their associated emissions. This was used to identify critical hot spots of emissions within the various construction supply chains. The results show that there is wide discrepancy between the emissions intensity of the construction industry for the 44 countries, ranging from 0.165 kgCO2e/Euro to 2.05 kgCO2e/Euro. In addition, the most significant contributors to emissions for the most emissions intensive countries are the production of concrete and steel. This in-depth analysis of global construction industries using multi-regional input-output data provides critical information needed to identify opportunities for reducing global construction-related greenhouse gas emissions. This will help prioritise future emissions reduction efforts within the construction industry and target specific solutions to achieve the greatest improvements to the overall environmental performance of global construction industries.
Subcontractors’ Health and Safety Compliance on a Water Board’a Projects
Authors: Moshanyana L , Smallwood J 
Published: February 2022

Abstract
Compared to other industrial sectors, the construction industry is responsible for a disproportionate number of fatalities and injuries. Subcontracting constitutes a significant portion of all construction projects, and it is noted for its adverse H&S influence in the industry. Health and safety (H&S) risks related to subcontracting pose a significant business risk to principal contractors (PCs) who employ subcontractors (SCs). Some PCs report that their sites have been shut down because of poor H&S compliance by the SCs. This situation has a negative impact on time schedules, and the overall profitability of projects.
The study seeks to examine why construction SCs undertaking projects for a Water Board located in Johannesburg do not comply with H&S regulations. Quantitative methods were employed for the study. Literature was reviewed, followed by a questionnaire survey to obtain primary data. A total of 174 construction managers, supervisors, and H&S officers in the employ of PCs and SCs participated in the survey to gather data relative to SCs’ degree of compliance with H&S legislation, H&S regulations, and the Water Board’s H&S specifications.
The literature suggests that there is general H&S non-compliance on construction projects by SCs. The salient findings include: SCs on the Water Board’s projects do not comply with H&S legislation and regulations, and H&S specifications; SCs’ management is not trained in terms of H&S; PCs do not issue work stoppage orders relative to SCs’ unsafe acts / behaviour; SCs further subcontract; the contractual relationships between PCs and SCs are not clear due to unauthorised subcontracting, and H&S enforcement by PCs and the Department of Employment and Labour (DEL) is inadequate.
Recommendations include: PCs must ensure that H&S practices are implemented; PCs and the DEL must enforce H&S requirements, and a framework must be evolved for ensuring SCs’ H&S compliance on construction. must be evolved for ensuring SCs’ H&S compliance in construction.

Authors: Lepel A , Hajdu M 
Published: February 2022

Abstract
An influence line graphs for project planning show how the changes of a selected activity duration affect the project duration. The name comes from the structural analysis where influence lines show on the ordinates of a graph the variation of the magnitude of, e.g., the bending moment at a specific point as a unit load traverses across the structure. This paper examines the principles of project planning influence lines: it discusses how to depict the six criticality types of activities, and it also shows what kind of transitions are possible among the criticality types. The findings help the greater understanding of the effects of the activity duration changes on the project duration.
