This paper critically analysed 195 articles with the objectives of providing a clear understanding of the current City Information Modelling (CIM) implementations, identifying the main challenges hampering the uptake of CIM and providing recommendations for the future development of CIM.

This paper adopts the PRISMA method in order to perform the systematic literature review.

The results identified nine domains of CIM implementation including (1) natural disaster management, (2) urban building energy modelling, (3) urban facility management, (4) urban infrastructure management, (5) land administration systems, (6) improvement of urban microclimates, (7) development of digital twin and smart cities, (8) improvement of social engagement and (9) urban landscaping design. Further, eight challenges were identified that hinder the widespread employment of CIM including (1) reluctance towards CIM application, (2) data quality, (3) computing resources and storage inefficiency, (4) data integration between BIM and GIS and interoperability, (5) establishing a standardised workflow for CIM implementation, (6) synergy between all parties involved, (7) cybersecurity and intellectual property and (8) data management.

This is the first paper of its kind that provides a holistic understanding of the current implementation of CIM. The outcomes will benefit multiple target groups. First, urban planners and designers will be supplied with a status-quo understanding of CIM implementations. Second, this research introduces possibilities of CIM deployment for the governance of cities; hence the outcomes can be useful for policymakers. Lastly, the scientific community can use the findings of this study as a reference point to gain a comprehensive understanding of the field and contribute to the future development of CIM.

The purpose of this research is to show that reliability analysis and its implementation will lead to an improved whole life performance of the building systems, and hence their life cycle costs (LCC).

This paper analyses reliability impacts on the whole life cycle of building systems, and reviews the up‐to‐date approaches adopted in UK construction, based on questionnaires designed to investigate the use of reliability within the industry.

Approaches to reliability design and maintainability design have been introduced from the operating environment level, system structural level and component level, and a scheduled maintenance logic tree is modified based on the model developed by Pride. Different stages of the whole life cycle of building services systems, reliability‐associated factors should be considered to ensure the system's whole life performance. It is suggested that data analysis should be applied in reliability design, maintainability design, and maintenance policy development.

The paper presents important factors in different stages of the whole life cycle of the systems, and reliability and maintainability design approaches which can be helpful for building services system designers. The survey from the questionnaires provides the designers with understanding of key impacting factors.

The purpose of this paper is to identify and assess the factors affecting building services’ coordination during the design development and review stages of building projects.

Literature review and interviews were conducted to identify the factors affecting building services’ coordination. In total, 36 factors were identified under six categories: planning phase of the project; design of mechanical, electrical and plumbing (MEP) systems; construction of MEP systems; operation and maintenance of MEP systems; owner; and design team and tools used. This formed the basis of a questionnaire survey designed utilizing a 5-point Likert scale of importance. The survey was assessed by practitioners in the Eastern province of Saudi Arabia.

The top five factors include the scale and complexity of the project, the level of experience of the design team, the quality of the preliminary/conceptual design of the building project, the clarity of the requirements and objectives provided by the owner, the allotted budget for the project and communication skills of the design team members. A high level of agreement between A/E professionals and contractors, and between contractors and facility managers was noted. The research provides the ranking of the identified factors for prioritization.

The paper provides stakeholders in the building services industry with the ranks of the factors that affect building services’ coordination.

The study provided a significant contribution to research and industry, especially in the regional context, where few studies have been conducted. The findings of the study will help in the reduction of construction wastes, delays and cost over-runs.
