- Description: Abstract: The quest for smart cities and development has been on the increase among infrastructural development stakeholders, including clients, government agencies responsible for the management of infrastructures, construction professionals, sponsors, and financiers of these projects. However, studies around the world have shown that less attention is being paid by these stakeholders to various indices and measures of smart cities. These measures and indices, known as drivers, are smart environment, smart economy, smart people, smart governance, smart mobility, and smart living. Using these drivers and their indicators, a multiple-choice questionnaire was designed in line with existing and relevant literature materials in the subject area. These questionnaires were administered on construction professionals with relevant and adequate knowledge of smart construction. Smart environment was found to be a major driver of a smart city while smart people, smart governance and smart living are also key to the achievement of the goals and objectives of the concept. The developed key smart city drivers are a workable, adaptable and efficient city design mechanism and it will be useful for city planners, statutory agencies as well other stakeholders in the development of smart cities.

- Description: Abstract: Communication management is viewed as an imperative factor associated with performance improvement in construction projects. In Eswatini, it is established that projects experience poor project delivery associated with poor communication management practices. This study seeks to elucidate communication management practices informed by local culture and relate it to project outcome. A questionnaire survey of practitioners registered with Eswatini construction industry council was adopted for the study. Data was collected from 66 respondents. Principal axis factoring established nine practices namely; information technology, communication technology, communication skills and competence, communication management plan, teamwork, clear channels within organisation’s structure, project brief requirement management, project brief risk requirement management and context of environment as being key factors to project positive outcome. Spearman’s rho established...

- Description: Abstract: The embracement of smart city approach as a sustainable system for the management and delivery of infrastructural developments has been on the increase, especially in developed and some developing countries. For this to be successful, cities in these countries, particularly in developing ones like South Africa, needs to be resilient because even though resilience can be achieved by making cities smart, smartness does not bring resilience by default. Thus, this study examines various factors influencing the ability of cities to develop resilience through smart city drivers. A survey of construction professionals involved in the design, planning, development and general management of cities and their infrastructure was carried out with the aid of a well-structured questionnaire. Factors influencing resilience were grouped into five divisions which are climate change, education, food security, public safety and threat to disease, in order of their importance. Findings revealed that the most important of these factors are the development of literacy and technical skills of citizens, regeneration of agricultural land and increased localised food production. The paper further examined the effects of these factors on six smart city drivers and found out that smart economy has the most influence on the resilience of a city. It was concluded that stakeholders concerned with the achievement of resilient smart city must

- Description: Abstract: Transportation infrastructure contributes to the development of an economy. However, the performance of such infrastructure is hampered if sustainability elements are not considered at the initiation/conception and operation stages of the projects. The study aimed to validate a structure of transportation project sustainability measures to evaluate projects and ensure continual delivery of intended benefits in the long run. Empirical data were collected using a field questionnaire survey developed from the literature review and a preliminary qualitative inquiry. A total of 132 built environment professionals were included based on purposeful and snowball sampling techniques. A model-generating confirmatory factor analysis was undertaken to validate underlying structures of sustainability measures established from a...
