Purpose Service quality is a major determinant of business performance. Empirical evidence from the literature indicates that, to attain a high level of customer satisfaction, a high standard of service quality should be provided by the service provider. This study aims to examine the relationship between the perceived service quality and the indicators of client satisfaction with particular reference to engineering consultancy services in building projects. Design/methodology/approach A survey research approach was adopted using a semi-structured questionnaire as an instrument of data collection. The questionnaire survey formed the basis for the descriptive and inferential (Pearson correlation and multiple regression) statistics that were used to evaluate the relationship between engineering consultants’ service quality and clients’ satisfaction indicators. Findings The study identified 10 key technical indicators and 10 key managerial indicators for measuring client satisfaction. Statistical analysis shows a positive significant relationship between the perceived service quality and all the indicators of client satisfaction. The positive correlation values show that as perceived service quality increases, both technical and management indicators of client satisfaction equally increase. Originality/value The results offer opportunity for professional service providers to continuously develop the technical and management indicators, embrace personnel training and key into continuous professional development for better service quality.

Purpose Clients in Nigeria have continuously questioned the quality of services being rendered by architectural firms in building projects. This study aims to investigate the areas of service responsible for determining client satisfaction. Design/methodology/approach The study uses questionnaire for data collection on perceived service quality and indicators of clients’ satisfaction. Findings The results of descriptive statistics suggest that efficient analysis and compliance with client brief along with buildability, flexibility and comprehensiveness of the design are the main technical determinants of clients’ satisfaction. Management measures for engendering clients’ satisfaction include team communication and collaboration as well as regular site visits when required. The study established a significant relationship between the perceived service quality and client satisfaction. At technical level, economical design and compliance with budget, buildability, optimal and error-free design and timely delivery have significant correlation with the perception of service quality, which could engender client satisfaction. At management level, collaboration and coordination, integrity and trust, regular site visits and project management knowledge and skills had significant relationships with perceived service quality. Originality/value To improve overall client satisfaction, architects are expected to focus on these factors in the process of service delivery. Architects’ expertise and skills can be further harnessed through continuous training and understanding of the project environment.

Despite global efforts at promoting environmental sustainability through development of Green Infrastructure (GI) facilities at urban centres; social menaces, depletion and wrong use of green spaces still persists in many developing nations. Indeed, attitude of residents towards the use of these facilities have not been commensurate to the reasons why the GI facilities were created. This study therefore examines the socio-demographic factors associated with visiting GI sites among residents of Lagos Metropolis, Nigeria. Multi-stage sampling technique was used to select 1560 participants in a questionnaire survey. Descriptive statistics was used to explore data distributions while Chi-square test was used to investigate residents’ socio-demographic characteristics associated with visit to green infrastructure sites in the study area. Participants were mostly men (58.6%) and younger than 50 years old (85.8%). Percentages of residents visiting GI facilities for either spiritual exercises (male=26.4%, female=23.8%) or joblessness (male=48.9%, female=52.1%) is higher than percentages of residents visiting GI facilities for recreation/relaxation (male=24.7%, female=24.1%) activities in Lagos Metropolis. The study suggests among others that, the Lagos State government should develop GI facilities to enhance more opportunity for job generation, while more public orientation on positive attitude toward use of GI facilities should be emphasized ABSTRACT Despite global efforts at promoting environmental sustainability through development of Green Infrastructure (GI) facilities at urban centres; social menaces, depletion and wrong use of green spaces still persists in many developing nations.
