The incidence of disability is increasing globally over the past decades. Despite the increased proportion of disabled individuals, established fire emergency evacuation procedures for disabled in high-rise buildings are lacking attention. Hence, this paper aims to focus on investigating fire emergency evacuation procedures for differently-abled people in high-rise buildings.

To address the gap, the case study strategy under the qualitative research approach was deployed by focussing 10 high-rise buildings. Data collected through semi-structured interviews and document reviews were analysed using content analysis.

The study findings revealed that even though a fire disaster is a major area to be considered, there is a noticeable gap in legal requirements related to differently-abled fire evacuation in Sri Lanka compared to the global context. Moreover, it was identified that importance given to differently enabled fire evacuations procedures varied based on the type of high-rise facilities in which hospitals and hotels provided more importance compared to office buildings, apartments and shopping complexes. Further, the study has highlighted the main gaps in the evacuation procedures and improvements required. Lack of imposed regulations for disabled evacuation was identified as a major barrier hindering the development of effective fire evacuation procedures for disabled, which creates a cascading effect. Further, the consideration given to legal, organisational, individual and technological factors would assist in straightening the identified issues.

This research provides a clear insight into the necessity of focussing at disabled individuals when developing fire emergency procedures. Most importantly, this study had exposed the current gaps in fire emergency evacuation procedures for the disabled community. Understanding these gaps is of high value for industry practitioners to ensure disabled safety during a fire emergency.

Implementing these strategies helps meet the region’s increasing water demands, advance sustainable water management, improve the standard of living for nearby communities and promote the socioeconomic development of desalination plants in Sri Lanka’s DZ.

Compared to low-rise and mid-rise buildings, commercial high-rise buildings have severe maintenance management deficiencies due to the complex nature of the structure and building services incorporated. Previous studies have shown that implementing lean in maintenance is a recognised prominent strategy to enhance maintenance performance. Thus, this study aims to investigate how lean maintenance can be applied to improve maintenance management in commercial high-rise buildings in Sri Lanka.

This study adopted a case study method. Three commercial high-rise buildings were selected to conduct the empirical study. An expert survey is also conducted to validate the findings.

The findings of the study revealed that out of the eight cardinal types of lean maintenance waste, six are rooted in the selected cases: (i) excessive preventive maintenance, (ii) waiting (maintenance resources, tools, procuring of additional supplies and documentation and permits), (iii) transportation due to centralised maintenance, (iv) poor inventory management, (v) poor information handling and (vi) poor utilisation of labour. Then the study revealed strategies to eradicate identified lean maintenance wastes.

The findings of this study can be used to guide maintenance practitioners in implementing lean maintenance in Sri Lankan commercial high-rise buildings. Furthermore, the proposed strategies can be directly applied to mitigate identified maintenance wastes.

This paper provides information on how high-rise commercial buildings in Sri Lanka can enhance their maintenance management by mitigating lean maintenance wastes.

The creation of occupant satisfaction can be reached through the involvement of building performance mandates (BPMs) while enhancing the functionality of buildings. BPMs comprise five mandates namely, spatial performance, thermal performance, indoor air quality performance, acoustic performance, and visual performance. BPMs have been recognized as a vital element when refurbishing post-fire apparel buildings. However, the evaluation of post-fire refurbishment projects is mainly focused on mechanical and physical properties while ignoring the BPMs. Further, there is insufficient literature on the BPMs in post-fire building refurbishment. Hence, the purpose of this research is to identify the importance of BPMs, and its challenges and propose strategies to enhance the building performance of post-fire refurbished apparel manufacturing buildings in Sri Lanka.

The study was conducted by involving a qualitative research approach. An extensive literature review and eighteen semi-structured interviews under three fire-affected apparel cases were involved as data collection methods and collected data were analyzed using content analysis.

Findings highlighted the procedure of post-fire refurbishment and the importance of BPMs for apparel buildings to enhance building performance in post-fire situations. The research identified 42 challenges encountered in maintaining BPMs of post-fire refurbished apparel buildings and provided 70 strategies to overcome the identified challenges.

This study offers a comprehensive analysis of challenges in maintaining BPMs and strategies to overcome the identified challenges which facilitate enhancing the performance of post-fire refurbished apparel buildings in Sri Lanka.

Project-based industries face major challenges in controlling project cost and completing within the budget. This is a critical issue as it often connects to the main objectives of any project. However, accurate estimation at the beginning of the project is difficult. Scholars argue that project complexity is a major contributor to cost estimation inaccuracies. Therefore, recognising the priorities of acknowledging complexity dimensions in cost estimation across similar industries is beneficial in identifying effective practices to reduce cost implications. Hence, the purpose of this paper is to identify the level of importance given to different complexity dimensions in cost estimation and to recognise best practices to improve cost estimation accuracy.

An online questionnaire survey was conducted among professionals including estimators, project managers, and quantity surveyors to rank the identified complexity dimensions based on their impacts in cost estimation accuracy. Besides, in-depth interviews were conducted among experts and practitioners from different industries, in order to extract effective practices to improve the cost estimation process of complex projects.

Study results show that risk, project and product size, and time frame are the high-impact complexity dimensions on cost estimation, which need more attention in reducing unforeseen cost implications. Moreover, study suggests that implementing a knowledge sharing system will be beneficial to acquire reliable and adequate information for cost estimation. Further, appropriate staffing, network enhancement, risk management, and circumspect estimation are some of the suggestions to improve cost estimation of complex projects.

The study finally provides suggestions to improve cost estimation in complex projects. Further, the results are expected to be beneficial to learn lessons from different industries and to exchange best practices.

Facilities management (FM) has become a revolutionary profession, which adds value to the built environment. Compared to other industries, the development of the FM industry is at a preliminary stage owing to poor adaptation of digitalisation. Although FM procurement process has improved over time, it is still complex, inefficient and challenging with the lack of digital innovations. Blockchain technology has emerged as a revolutionary digital technology under “Procurement 4.0”. The purpose of this paper is to develop a framework that enables the effective use of blockchain technology for FM procurement process.

Data collection using interviews was performed in two stages adopting a mono method qualitative methodological choice using case studies and survey strategies. Template analysis and content analysis techniques were used to analyse the collected data.

Through the findings, main steps in the current FM process were identified. It was revealed, manual procurement has issues related to, efficiency, data security, communication and transparency. Similarly, e-procurement systems also have issues related to data security, poor integration and transparency. FM industry has identified the requirement of transforming into an advanced digitalised technology-based procurement system. This study revealed, blockchain features to overcome these issues and the application of blockchain technology in different steps of the procurement process through the developed framework.

The developed framework offers a solution for the future technological transformation of FM procurement using blockchain technology.

In this present globalised era, outsourcing has become a very popular and much sought after procurement strategy for facilities management (FM). Generally, a sustainable procurement system should be capable enough to deliver the services free of disruptions. However, outsourcing can bring about changes in working patterns, organisational culture and management styles which can possibly disrupt the activities of an organisation. In order to avoid such disruptions, organisations need to adopt a measured approach towards this change. Accordingly, the purpose of this paper is to investigate the importance of change management to enable sustainable outsourcing of FM services.

Within commercial building context, the questions of “why change is not managed during outsourcing of FM services” and “how can it be managed” are investigated through case studies.

Organisations encountered various disagreements due to inadequate management of change during outsourcing. If the changes emanating from outsourcing are not managed satisfactorily, it would result in possible disruptions. However, to make changes happen successfully is one of the most challenging tasks faced by the leadership and corporate management of the organisations.

In order to facilitate the practitioners in the industry, this paper finally offers a framework for change management during outsourcing based on the findings.
