“…The questionnaire contained three sections. Section one collated the demographic profile of respondents; section two gathered quantitative interval data on a 5-point Likert scale to measure the CSFs of cyber technology (Table 1), where 5 = extremely high, 4 = high, 3 = average, 2 = small, and 1 = no or very small, as frequently used in previous studies [43][44][45][46][47]; and section three gathered qualitative openended data on questions that sought further information on the essential CSFs identified. To ensure robust ethical compliance, all participants were assured that all data would be kept strictly confidential, no personal details would be divulged nor disseminated, and data collected would be retained on a secure server and destroyed upon completion of this investigation.…”

“…A convenience sampling technique was used in the research to ensure that there is an equal chance of every member being selected. Moreover, a methodological purpose analysis was used to determine the sample size [43,49]. The questionnaire was administered to 119 people using a postal survey and 98 completed questionnaires were retrieved, constituting an 82% response rate.…”

We sought to identify and examine the critical success factors (CSFs) necessary for incorporating cyber technology into residential building projects to augment operational performance and sustainability. An iterative two-stage approach was adopted to explore the phenomena under investigation. General CSFs for cyber technology were first identified from the extant literature, and subsequently explored using primary questionnaire survey data accrued from professionals within the Nigerian building industry. The survey results illustrated that the availability of sensors, good communication networks, mobile devices, and device layers and the creation of workable virtual modes are the main critical success factors for adopting cyber technology. Moreover, Gini’s mean difference measure of dispersion showed that the success factor in stationary cyber technology adoption is government support. The study’s findings guide building industry stakeholders to embrace cyber technology to improve cost and sustainability performance in the Nigerian building industry. Due to the originality of the findings of this study, a strong basis is provided for critically evaluating and analyzing the many vital aspects of cyber technology success.

“…A major cause of delayed payment can be attributed to the Client's poor financial management [32]. Funding infrastructure projects require sizable investments, and in the absence management and financial controls, moral adversities are likely to occur in the procurement of goods and services by public and private entities.…”

“…In Ghana, complicated contractual processes and the client's poor financial management are critical delayed payments causative factors [41]. The neighbouring region of Nigeria, Odenigbo et al [56] found that submission of claims with errors and slow variation approval processes occur frequently In Malaysia, numerous significant causes of delayed payments to contractors were identified and mirror issues occurring in T&T, such as the client's poor financial management, contractual disputes and cultural attitudes [32]. These similar causations experienced amongst all these countries all contributes to the deliberate withholding of payments to contractors.…”

The consideration of payments to contractors is not only a legal obligation but a necessity for assuring the continuity and completion of a construction project. However, consistent payments to facilitate project cash flows are uncommon in the construction industry. Within the context of a small island developing state, this paper aims to uncover leading risks factors the contributing to implications of delayed payments, on contractors’ cash flows and uncover any causalities and effects on relationships among these factors. A two-tiered quantitative approach was adopted. Firstly, a compiled list of delay factors was collated from the literature review. Semi-structured interviews were conducted with experienced construction professionals to determine the factors’ relevance and applicability in Trinidad and Tobago. A closed-ended survey questionnaire was subsequently developed and administered to primary construction stakeholders. Secondly, the responses obtained were collated, validated, and ranked using the relative importance index. A confirmatory factor analysis (CFA) was carried out using SPSS, and thereafter, SPSS Amos was used to determine the best-fit Structural Equation Model (SEM). The results strongly indicate that the issue of delayed payments is very prevalent within public sector projects. Unstable political climates and the delay in employers’ issuance of variation orders were found to be the main causes of delayed payments within the industry. Delays in sub-contractor and supplier payments as well as an increase in the contractor’s debt are the leading effects of delayed payments on the contractor’s cash flows. Based on these findings, a risk response framework was outlined to assist small to medium-contracting enterprises cope with payment delays, both locally and internationally. This research contributes to the advancement of construction management knowledge by informing construction professionals and policy makers of the implications of delaying approved payments, the consequential causes and effects, and a risk response technique to mitigate the negative effects on contractors’ cash flows.

Urban waste water management paradigm evolution: Decentralization, resource recovery, and water reclamation and reuse

The growing urban population, increasing income per capita, and significant rise in the number of people living in cities are all placing a strain on the nation's water supply and calling for innovative methods of urban water management. Water stress, excessive resource consumption, nutrient discharge into aquatic ecosystems, and financially unstable utilities are all consequences of the traditional linear “take, make, waste” approach to water management. Many strategies are required to achieve economic, environmental, and social sustainability. More closed‐loop urban wastewater and resource management systems can be developed and implemented with the help of a toolkit that includes stormwater management/rainwater harvesting, water conservation, water reclamation and reuse, energy management, nutrient recovery, and source separation. Water conservation, water reclamation, and wastewater reuse are becoming the norm in many water‐poor regions. This shift is hastened by decentralization, made possible by dispersed stormwater management/rainwater collection and innovative high‐performance treatment technologies. Similar changes are occurring in conventional methods of residual management due to the need for more energy recovery and nutrient recovery and reuse. Finding the most outstanding long‐term solutions requires an economic study done well. The practice of stove‐piping must be eradicated from urban wastewater and resource management. These novel techniques for managing urban wastewater and resources can produce more long‐term, financially stable, resource‐efficient, environmentally friendly, nutrient‐sensitive, and sanitary outcomes.
