More so, the sentimental attachment of high-rise buildings to the culture, prestige, and wealth of a nation necessitates the need to preserve investment made on high-rise buildings via proper maintenance of their facilities
. Consequently, in order to guarantee the long-term viability of the investments made in these structures, it is necessary to safeguard them by maintaining the building fabrics, building systems, and building services, all of which will enable occupants to live comfortably
The term facility management is referred to as an integrated approach to operate, maintain, improve, and adapt the facility of an organization in a way to ensure an ambience that strongly supports the core business of the organization
[14]: the concepts of cost-effectiveness, productivity improvement, efficiency, and employee quality of life. Facility management processes, facility management functions, and facility management activities are common terms that are often used interchangeably when explaining facility management practice
[15]. Although these terms are synonymously used, there exists a defining line of differentiation amongst them
[16]. Facility management processes are considered to be a strategic way of harmonizing the organizational structure, work processes and the enabling physical environment that will mirror facility dimensions in the organization’s strategic plans
[17]. Using a ProFacil model, Ref.
[18] categorized facility management processes into five generic activities: these are operating facilities, providing new facilities, providing rebuilt facilities, providing maintained facilities, and performing disposal of facilities. Another study by
[19] identified six main facility processes, with twenty-seven subprocesses, of a typical office building, and these are identifying the facility; identifying the characteristics of tenants; developing a facility management plan; implementing operation and maintenance; collecting new information; and responding to and analyzing performance complementary actions.
Lastly, building facilities and auxiliary operations for the control and maintenance of property and equipment are the main focuses of facility management activities, which were coined to mean hard and soft services. These activities include work/systems control and optimization; procedures; scheduling; and routine, preventive, scheduled, and unscheduled tasks performed with the intention of preventing equipment failure or decline in order to increase efficiency, dependability, and safety
[1][21][22][23]. It is worth noting that facility management started as an offshoot of property management, and it was first provided in the United States of America and Europe four decades ago; meanwhile, the discipline gained prominence in Nigeria in 1997
[24]. It has since undergone evolution, ranging from being perceived as an overhead cost that needed to be kept to its barest minimum to a strategic business plan dimension
[17]. Meanwhile,
[23] stated that the evolution of facility management practice is centered around digitalization and sustainability. The study stated that the advances in information and communication technology aided the development of facility management when “office for the future” and paperless concepts were launched in the 1970s. The authors further stated that successive developments in office designs were results of the invention of globalized wireless communications that transformed the world into a “global village”. Ref.
[25] carried out a comparative study on the delivery of facility management services between publicly and privately owned high-rise residential buildings in Lagos. Residents of the selected high-rise buildings (Eko Court complex and Niger Towers) were sampled. The mean value expectations and the mean value of perceptions of the delivery of facility management services were measured using the Service Quality Measurement (SERQUAL) model. The study revealed the availability of all facilities needed for safe and comfortable occupation of residents in the high-rise buildings. It further stated that Eko Court outsourced its facility management services, while Niger Tower adopted a hybrid facility management strategy. It was found out that the residents of Niger Tower were more satisfied with the level of facility management service provided, although residents of both residential buildings were not highly satisfied with the facility management services provided by the building operators. It then concluded the residents’ perception and expectation of facility management services can be positively enhanced by giving close attention to improving dissatisfying factors. The study recommended improving the standardization of services, the customization of services, the creation of a feedback channel, and the adoption of appropriate service recovery techniques as means of improving facility management service quality. The focus of the study is on the satisfaction of facility management service delivery in high-rise buildings based on residents’ perception. However, their expectation and perception of what effective facility management service should be may not be accurate.
3. Facility Management Automation
Ref.
[4] stated that structures built in Nigeria decades ago are getting old, and technological evolution of facility management practice makes the use of automation in the management of buildings, most importantly high-rise buildings, a necessity
[26]. Furthermore, recent developments in the built environment have shown that the orientation of national economies, societies, and environments has undergone significant, long-term shifts
[27]. Several factors have contributed to the evolution of the built environment’s structure, practices, and overall functioning, including globalization, institutional and structural reforms, the liberalization of global financial markets, shifting economic policies, technological innovations and advancements, environmental sustainability, rapid urbanization, economic pressure, and the rise of emerging market economies
[28]. Nevertheless, these concerns will have a significant impact on how our society functions going forward and will guide our decisions about how to manage the built environment
[29].
The nature and purpose of building amenities are said to be constantly changing in response to technological advancements and the general digitization of our contemporary environment, as stated by references
[30][31]. The findings went on to say that these advances in technology have forced building operators to always come up with new approaches to managing and controlling facilities. Through the use of information technology, sometimes known as facility management automation, they are progressively aiming for more control over the resource utilization rates of their facilities for a more cost-effective, environmentally friendly, and optimized facility management experience.
Automation provides facility managers with the means and instruments to facilitate the administration of facilities, accelerates the execution of facility management tasks, and acts as a unifying element for people, places, and facilities
[22][32][33][34][35]. Three main topics have been covered in the discussion of automation’s roles in the service sector
[36][37]. These tasks include providing utility and support infrastructure for service innovations, as well as describing information communication and technology (ICT) as an enabler of service innovations. Automation has been shown to perform the aforementioned roles in facility management practice
[38][39]. It has been proven that the facility management sector is one of the services.
As an ICT enabler, different automating systems [data containers and workflow systems, such as building information modeling (BIM), computer maintenance and management systems (CMMS), computer-aided facility management (CAFM), and integrated work space management systems (IWMS)], digital twins (DT), and the Internet of Things (IoT) have been developed to enhance facility management practice
[33]). As a support infrastructure for a service innovation, facility management automation supplements facility management functions, while as a utility for service innovation, facility management automation has a positive impact on cost and time savings, minimizing errors, omissions, and rework
[40][41][42]. These automating tools help in error detection and maintenance and aid thermal comfort occupant monitoring and cost saving maintenance.
Ref.
[36] carried out a review of the literature on information technology in facility management. Data repository technology; BIM (interoperability software); Industry Foundation Class (IFC) workflow systems; CAFM (facility intelligence software); building maintenance system (BMS) sensor mobiles; augmented reality (AR); and field capture technology (drones) are the common automating systems used in facility management practice. It further stated that BIM is the most researched technology, while CAFM is the most used technology. The study lacks empirical data to support the author’s opinion. Ref.
[5] revealed in their findings that CAFM is the most popular and the most used automating system in the facility management of high-rise buildings in Lagos, Nigeria.
According to
[43], the digital twin, which is a more recent automating tool that integrates the physical product, virtual replica, and IoT, is a digital replica of a facility that shows its structure, accommodation details/spaces, flow of movements, and so on. The study stated that research on the use of DT in facility management can assist in assessing building performance through the real-time flow of data. A number of studies
[43][44][45][46][47] have discussed the importance of DT in facility management to include: maintenance error detection and predictions; enhancing thermal comfort and occupant monitoring; prediction and cost saving; sharing a more equal representation; building performance; and room experience. These studies were carried out in developed countries with innovative technologies and supportive systems. Also, discussion on the importance of automation in facility management has gained popularity in the developed world. However, majority of these studies have been generic; the study focuses on the relevance of automation in facility management of high-rise buildings in developing countries using a case study of Lagos, Nigeria.
