This paper aims to identify the different system approach using Building Information Modelling (BIM) technology that is equipped with decision making processes. Maintenance planning and management are integral components of the construction sector, serving the broader purpose of post-construction activities and processes. However, as Precast Concrete (PC) construction projects increase in scale and complexity, the interconnections among these activities and processes become apparent, leading to planning and performance management challenges. These challenges specifically affect the monitoring of façade components for corrective and preventive maintenance actions.

The concept of maintenance planning for façades, along with the main features of information and communication technology tools and techniques using building information modeling technology, is grounded in the analysis of numerous literature reviews in PC building scenarios.

This research focuses on an integrated system designed to analyze information and support decision-making in maintenance planning for PC buildings. It is based on robust data collection regarding concrete façades' failures and causes. The system aims to provide appropriate planning decisions and minimize the risk of façade failures throughout the building's lifetime.

The study concludes that implementing a research framework to develop such a system can significantly enhance the effectiveness of maintenance planning for façade design, construction and maintenance operations.

The construction industry has actively attempted to tackle the low-productivity issues arising from inefficient construction planning. It is imperative to understand how construction practitioners perceive technology integration in construction planning in light of emerging technologies. This study intended to uncover unique experimental findings by integrating 4D-building information modelling (BIM) to virtual reality (VR) technology during construction planning among construction professionals at light steel framing (LSF) projects.

The building industry participants were invited to provide inputs on two different construction planning methods: conventional and innovative methods. The conventional method involved the participants using traditional platforms such as 2D computer-aided design (CAD) and physical visualisation of paper-based construction drawings for the LSF assembly process with a Gantt Chart tool to complete construction planning-related tasks for the targeted project. Comparatively, participants are required to perform the same tasks using more innovative platforms like 4D-BIM in a VR environment.

A Charrette Test Method was used to validate the findings, highlighting an improvement in usability (+10.3%), accuracy (+89.1%) and speed (+30%) using 4D BIM with VR compared to the conventional paper-based method. The findings are also validated by a paired t-test, which is supported by the rationality of the same findings. This study posits positive results for construction planning through the utilisation of modern practices and technologies. These findings are significant for the global construction industry facing low productivity issues, delays and certainty in terms of building delivery timelines due to poor construction planning.

This new blend of technologies—combining 4D BIM and VR in industrialised construction projects—potentially directs future initiatives to drive the efficiency of construction planning in the building lifecycle. The interactive BIM-based virtual environment would purposefully transform construction planning practices in order to deliver modern and more certain building construction methods with a focus on prefabrication processes.

The purpose of this paper is to highlight the regulatory barriers to achieving sustainable buildings in Kosovo. The present paper focuses on regulatory barriers viewed from the perspective of construction industry experts in achieving sustainable buildings.

The present study uses a qualitative research method and semi-structured interviews as a research instrument. The present study interviews around 20 experts in construction and property management, property development, spatial planning and energy management.

The study finds that Kosovo building laws and regulations provide for the materials assessment criteria, but the materials assessment criteria are only for mechanic strength. The study further finds that the sustainability concept is not included and incorporated in Kosovo's urban planning laws and regulations. The study also finds that despite specific clauses mentioning energy performance certificates in the Law on Energy Performance of Buildings in Kosovo, energy performance certificates appears to be not enforced and the nature of the barrier is more organizational rather than regulatory. Finally, the study finds that Kosovo laws are silent as far as green labeling of building materials is concerned.

The implication of the present finding is that policymakers in Kosovo not only should include clear sustainable materials assessment criteria in the law, but also enforce those criteria through testing and inspection mechanisms included in the law and implemented in practice through funding and organizational support. Nonetheless, policymakers in Kosovo should contemplate amending the urban planning laws in Kosovo and include both the term of sustainability at the planning level and conformity guidelines for sustainable design that can be done at the administrative directive level. Further, the clauses in the law do not suffice if the clauses are not accompanied by specific systemic and organizational support in the issuance of energy performance certificates. Policymakers in Kosovo should be proactive in designing clauses that specify green labeling standards for materials; however, these labeling standards should not adversely affect the cost of construction and reduce the demand for real estate.

The study is the first qualitative study about the perception of construction professionals in Kosovo, regarding the regulatory barriers of sustainable buildings in Kosovo.

The aim of the study is to provide a comprehensive understanding of interrelations of structural systems and main planning considerations in supertall buildings (≥300 m).

Data were collected from 140 contemporary supertall towers using the case study method to analyze structural systems in the light of the key design considerations to contribute to the creation of more viable supertall building projects.

Central core typology, outriggered frame system, composite material and tapered prismatic and free forms were the most preferred features in supertall building design. Shear walled frame and tube systems occurred mostly in the 300–400 m height range, while outriggered frame systems were in the range of 300–600 m in height. Asia, the Middle East and North America mainly preferred outriggered frame systems, followed by tube systems. Considering the building function and form, the most preferred structural system in each of these groups was outriggered frame system, while mixed-use function stood out in all structural systems except in shear walled frame system.

To date, there has been no comprehensive study in the literature of the interrelations of structural systems and important planning considerations in the design of contemporary supertall towers through a large set of study samples. This critical issue was multidimensionally explored in this paper in light of 140 detailed case studies of supertall buildings around the world.

Globally, several studies have shown that hospital building is charged with multiple inherent risks because a large number of users are vulnerable in tragic events. Thus, the need for the fire safety management plan (FSMP) has been proved as an instrument to mitigate fire and related risks in healthcare facilities. In Malaysia, FSMP regarding public healthcare building is yet to be explored in-depth. Therefore, this paper explores the information necessary to develop the FSMP framework for public hospital buildings.

The paper’s objectives were accomplished via a combination of five face-to-face interviews and observations of five selected public hospitals in Pulau Pinang, Malaysia. The five key participants were across the five public hospitals and collated data analysed through thematic analysis with the assistance of MAXQDA 2018.

Findings show that fire safety stakeholders practice system, fire safety action plan and fire risk management were the three main variables that promote fire safety programme and will improve FSMP for Malaysia’s public hospital buildings.

This paper’s data collection is limited to Penang, Malaysia, and a qualitative research approach was used, but this does not deteriorate the strength of the findings. Future studies are needed to consider validating findings from this paper via a quantitative approach.

The suggested framework can be employed by Malaysia’s public hospital authorities as a guideline to mitigate fire hazards in the country’s healthcare facilities.

This paper is encouraging hospital operators and other key stakeholders to improve on their FSMP for healthcare buildings across Malaysia as part of the study implications.

Unprecedented levels of investment in transit and transit-oriented development in Los Angeles County have not resulted in gains for transit-dependent populations or overall higher ridership for that matter. They have instead saddled them with inordinate cost burdens and displacement pressures. Yet racialised, low-income communities that rely on transit are far from passive victims. Rather, they are participating in advocacy campaigns that penetrate decision-making venues and procedures and co-create institutional practices, policy priorities, and public and private investments that serve their interests and build a Los Angeles that is more widely accessible and affordable. This chapter presents a case study of the Alliance for Community Transit-Los Angeles (ACT-LA), a regional coalition of over 40 community-based organisations at the helm of direct-action policy campaigns and participatory planning initiatives to advance transit justice and equitable transit-oriented communities (TOC). After examining ACT-LA's origins in the LA-based movement for community benefits agreements, the analysis focuses on how ACT-LA has combined political mobilisation for ballot-box measures with participatory policy-making and planning processes to advance just, equitable, sustainable transit systems, and TOC. The concluding discussion considers the implications of the ACT-LA case for reformulating participatory policy-making and planning around transportation and land use to further equity and climate goals.

Urban population growth has increased housing density, which has expanded the construction of low-cost low-rise residential in urban areas. Good building performance and effective low-cost low-rise residential quality lead to higher user satisfaction and improve building sustainability. This study aims to focus on the factors influencing the sustainability of low-cost low-rise residential in the West Malaysia urban area to assess resident satisfaction.

A mixed-mode approach with both qualitative and quantitative were used in this study. Semi-structured interviews were conducted with 12 stakeholders to identify the common factors influencing sustainability in low-cost low-rise residential. Subsequently, questionnaire surveys were formed and distributed among building users to determine the satisfaction level with low-cost low-rise residential building performance.

The finding demonstrates that accessibility is the key factor to achieving sustainability of low-cost low-rise residential. The finding also related to the factor that influences both stakeholders and building user satisfaction levels. This study also identifies key areas that require attention to improve user satisfaction with building sustainability and building performance of low-cost low-rise residential.

This study aims to determine stakeholder and building user satisfaction levels in relation to the sustainable building factor. A few indicators have been set up to identify the factors that most influence the sustainability and environment of low-cost low-rise residential buildings. Each subchapter has a few recommendations to improve the performance of low-cost low-rise residential. Each of the factors mentioned is related to social, economic and environmental sustainability. In addition, the study discovered a strong connection between low-cost low-rise residential performance and user satisfaction.

Inadequate strategic planning and maintenance budget may undermine the maintenance of the Higher Education Institution Building (HEIB). Studies have shown that a customised maintenance concept such as Soft System Methodology (SSM) can improve public building maintenance operations. There is a paucity of studies regarding public HEIB maintenance in Nigeria via an SSM approach. Therefore, the research investigated the state of public HEIB and developed a framework to improve public HEIB maintenance practices in Nigeria.

The research adopted SSM to understand Nigeria’s public HEIB maintenance practices. The SSM permitted a substitute approach to improve public HEIB maintenance practices via a developed framework. Data were collated via virtual interviews with experts, and findings were presented in line with the SSM seven steps.

Findings show that besides the shoddy state of public HEIB maintenance, there is no public digitalised HEIB framework to improve maintenance practices across Nigeria’s higher education institutions. The study developed a digitalised framework with the support of Computerised Maintenance Management System from the findings. It would reposition the public HEIB and stir up various agencies/departments/units managing maintenance for better service delivery via integrated delivery, practical, methodological and managerial aspects.

The research investigated Nigeria’s public HEIB maintenance practices via SSM to identify the required document and propose a feasible framework to improve Nigeria’s HEIB maintenance practices. Besides the developed conceptual framework, Nigeria’s HEIB maintenance practitioners and higher institution chief executives can use the recommended framework as guidelines to improve HEIB maintenance practices.

This paper aims to evaluate the level of compliance of fire safety with the legal requirements in Malaysia government hospital buildings by evaluating via fire risk management.

Five government hospitals were selected. These five hospitals were selected due to the location of Penang, which is one of the fast-growing states in Malaysia (Salleh, 2019; Ebekozien, 2019). This state is the second most densely populated state after Wilayah Persekutuan Kuala Lumpur, with an average distribution of 1,490 persons per square km. This higher population caused the higher demand on the health-care services by the public (DOSM, 2016). The observation and building audit processes are as described. Hundreds of photos were taken for qualitative analysis, and all fire safety elements were measured for the descriptive analysis for each hospital. The framework of audit elements is created based on the Life Safety Code: NFPA 101 (2018), UBBL 1984: Part VII (Fire Requirements) and Part VIIII (Fire Alarms, Fire Detection, Fire Extinguishment and Fire Fighting Access). The cross-sectional descriptive evaluation is conducted in the case studies building in accordance with Life Safety Code of NFPA, also known as NFPA 101. To conduct the study, the information needed to assess the fire safety status was extracted from the CFSES software based on the NFPA 101 standard and prepared and compiled by the researcher as a checklist. In the next stage, gathered information was analysed using Computerised Fire Safety Evaluation System (CFSES) software. This method was developed based on the NFPA 101 standard and evaluated the fire risk from four dimensions of containment, extinguishment, people movement and general safety. This software gives the risk assessment results in three areas of fire control, exits and general safety. To assess the fire risk of the commercial buildings after entering the background information (height, age, number of stories, etc.) in the software, the software first calculates the score that the building should obtain in the three aspects of fire control, exit routes and general safety (minimum score required).

The utmost zones in the case studies (44.3%) occupied by limited mobility are located at low-rise buildings or at the first floor to third floor of the hospital buildings. Hospitals managements lacked in creating the maximum exit route and egress the occupants to disclosed the building during evacuation, it correlates to the patients' mobility positions strategy to assign their categories that fell on effortless mobilisation. Surveyed hospitals were built with the non-combustible materials, even though four of the case studies were built before 1984. Hospitals were equipped with hazard separations and vertical smoke pores, and in most of the zones, sprinkler system is installed only in the corridors, equipped with communication system and system of communication with fire and relief organisations and has a fire detection and alarm system throughout the building. Results of fire risk assessment on four groups of elements were tested via CFSES revealed from 122 zones of surveyed hospitals; 102 or 84% of zones give the highest failed rate to comply the NFPA 101 requirements in terms of people movement in the building. The high-occupied Penang General Hospital contributed as the highest case study for not complying with the minimum requirements in all dimensions: people movement elements (41 zones), fire containment (31 zones), fire extinguisher (31 zones) and general safety (20). Fire extinguishment (62 zones) recorded the highest numbers of zones that complied with NFPA 101 (2013). The overall results of the fire risk assessment suggested that in terms of the fire control, egress and general safety aspects, the fire risk assessment score was unacceptable (failed) in all hospital buildings studied, and in the three areas mentioned, the general safety, egress/exit routes and fire control were in a worse status in terms of the score obtained in the software. None of the surveyed hospital received the minimum safety score in the three areas mentioned. The involvement of Emergency Response Team is crucial to overcome this egress or fire exit requirement and parameters.

Several limitations exist in this research that cannot be controlled. Firstly, the occupancy rates only determined during peak hour. Accessibility into hospital compound permitted only during daytime. Secondly, the fire safety audits and fire safety risk management in this research are not being conducted by a professional architect or engineer and as a result must be relied on the direct inspection checklist to create valid results. Thirdly, this research has some limitations which need to be noted but does not affect the robustness of the study’s findings. This study focuses only on five selected public hospitals in one state of the northern region of Malaysia and excluded data gathering from all other parts of Malaysia. The perception of hospital operators regarding fire safety issues from different state hospitals may allow comparisons.

The findings of this paper should make a key practical contribution to the body of knowledge. In practice, the proposed framework should expand the knowledge of public hospital fire safety management plan concerning the level of fire safety compliance with the requirements in government hospital buildings and develop a fire safety management plan framework for government hospital buildings.

This paper develops an early framework component related to the occupants’ safety which gives the basis for future research in hospital fire safety settings as it imparts early investigation into the consequence of investigating the phenomenon from the operators’ perspective as an attempt to improve public health-care fire safety performance in hospitals.

This paper has created a few measurement tools that can be applied among public hospital buildings stakeholders to perform the fire safety audit and risk management and rate the performance of Fire Safety Management in public hospitals.

Malaysia’s building regulation is mainly based on the Uniform Building By-Laws (UBBL) 1984 which provides guidelines on the procedures for building plans approval and other means of development control. However, the application of these by-laws varies between local authorities, as they are gazetted by different state governments. The formulation of UBBL 1984 which was originally formulated to address the need for a standardized set of building regulations for the country is now perceived as inconsistent and complex. Therefore, this research attempts to examine the discrepancies between state by-laws, particularly Federal Territory of Kuala Lumpur and national UBBL 1984.

Critical review of the content of the UBBL (Federal Territory of Kuala Lumpur) 1985 and national UBBL 1984 was carried out to pinpoint discrepancies between the two by-laws.

Differences between national UBBL and Kuala Lumpur By-laws fall into four main categories particularly terminology, prescriptive requirements, presence of terms and by-laws. Three editorial spelling and typing errors were also found in the national UBBL 1984. It is argued that the errors and differences lead to confusion and pose unnecessary regulatory burden to the construction industry which ultimately discourage people to disobey the rules. The identified discrepancies between these by-laws showed an urgent need to review the current building by-laws considering today’s technologies, norms and citizen needs.

To the best of the authors’ knowledge, this study is the first of many fruitful contributions that examine discrepancies between by-laws that govern building control matters in Malaysia. Although centred on legislation in Malaysia, the findings are relevant for governments around the world working towards improving public service delivery.
