Educational building performance evaluation practices and perceptions : a case of federal universities in South East NigeriaSource: Journal of Construction Project Management and Innovation 2, pp 314 –330 (2012)More Less
This paper assesses the level of awareness, perception and practice of Building Performance Evaluation (BPE) in the management of educational buildings. Hitherto performance evaluation of buildings has not received significant attention in Nigerian Universities. Universities procure buildings that neither respond to the demands of changing needs, nor fit for purpose. This study relies on current literature to explore how the constructs of BPE can be utilized to improve the design and management of educational buildings in the Nigerian university system. Data were generated using a convenient sample of construction professionals holding key positions in the physical planning and works departments of four Federal Universities in South East Nigeria. Data analyses were conducted using Excel and statistica; Version 9.0. The findings suggest that there appears to be an apparent lack of a systematic mechanism for measuring the success or performance of completed and occupied buildings in the universities. The absence of a performance evaluation database in the institutions explains this situation. The study reveals inadequate funding and lack of skilled personnel to conduct the performance evaluation of buildings. Consequently, the interaction between users and buildings did not add value to learning and working experiences. The paper concludes that a significant number of buildings in the case organisations were not fit for purpose. Furthermore, building performance indicators/measures identified as specific design objectives seem not have been explicitly expressed in most of the buildings investigated. The study emphasizes the need for designers and facilities managers to acquire skills on critical aspects of building performance evaluation as a means of meeting the increasing demand for higher quality in education. The exploratory nature of this research clarifies the problems that need to be addressed in future studies and so raised a number of theoretical and conceptual issues that must be explored in the performance evaluation of educational buildings.
Exploring key performance indicators for joint venture construction projects in Lagos State, NigeriaSource: Journal of Construction Project Management and Innovation 2, pp 331 –344 (2012)More Less
One acceptable way to extend company presence into a new market is through strategic alliances and joint ventures. These methods are being used with increasing frequency by engineering companies with mixed results. This research seeks to assess the key performance indicators for the performance of partners in joint ventures projects in Nigeria. Primary data were collected through the administration of questionnaire to partners and consultants who have engaged in joint venture construction project in partnership with the Lagos State Development and Property Corporation. The data obtained were analyzed using Mean Item Score, Wilcoxon-Mann-Whitney (U-test) test and Kruskal-Wallis (H-test) test and factor analysis. The study revealed that all the performance indicators identified were significant to joint venture construction projects with time performance, client satisfaction, cost performance and sharing resources ranked as the most important performance indicators for joint venture construction projects in Nigeria. A KMO value of 0.774 was gotten indicating the suitability of the data for factor analysis. The research would assist in deciding key performance indicators for joint venture construction projects for inclusion in the drafting of joint venture agreements. The three groupings from factor analysis and their relationship will help in developing a framework for joint venture construction projects. The factors extracted help to identify the high prioritized performance indicators which could be used as an assessment tool to evaluate the performance of partners and thus help to identify areas for improvement.

Lean construction, if adopted could prove to be highly rewarding to Ghanaian construction organizations, resulting in the reduction of waste and improvement in productivity. This paper presents results of a study to assess the perceptions of Ghanaian construction practitioners of the lean construction philosophy and to identify the level of knowledge in the construction industry. Structured questionnaire survey was conducted on technical managers of construction organizations and consultants to assess their perceptions of the lean construction philosophy and to identify the level of knowledge in the Ghanaian construction industry and measures to bridge the knowledge gap. A quantitative approach to data analysis was employed using mean scores of factors studied. There is the existence of a good level of awareness, but a low level of familiarity and application of lean construction among practitioners in the Ghanaian construction industry. Majority are considering the application of lean concepts in future. Lean principles are considered transferable to construction in Ghana and construction practitioners suggest that to deal with the knowledge gap, firms should change organizational culture that does not promote lean construction and the construction industry should organize workshops and conferences to increase the level of awareness and bridge the knowledge gap on lean construction in Ghana. The study should have covered all categories of contractors but due to lack of reliable information on small scale construction organizations, only large firms in the highest financial classes were covered. The findings from the study enable the Ghanaian construction industry to organize training workshops and conferences for key players in the industry to increase their level of awareness and to bridge the knowledge gap on lean construction. The findings of the study are of value to construction organizations seeking to improve productivity and work quality through the adoption of the lean construction approach.
Ghanaian construction professionals' perception on challenges to female retention in the construction industrySource: Journal of Construction Project Management and Innovation 2, pp 360 –376 (2012)More Less
The flow of knowledge from higher learning institutions into the construction industry is always disrupted when female graduates are not retained in the Ghanaian construction industry. This paper assesses challenges to female graduates' retention in the Ghanaian construction industry, and recommends measures to promote their retention and participation in infrastructure development. Questionnaires were administered through purposive sampling to 51 groups of male and female construction professionals in order to establish the gender differentiated perceptions on the challenges and measures to retain female construction graduates within the construction industry. Professionals from construction companies and consultancy firms were surveyed using self-administered questionnaires. Data was encoded into SPSS and analysed using both one sample t-test and Wilcoxon-Mann-Whitney two-sample rank-sum test. The survey instrument assessed the views of respondents on issues relating to the under-representation of women in the construction industry, challenges to their retention and measures to retain them in the construction industry. Professional men and women in the construction industry see better prospects in other industries, family commitments, long working hours and stressful work environment as some of the factors which push women away from the industry. Professional associations and regulatory bodies should use strategies such as mentoring, increase in role models, eliminating gender bias factors, giving career guidance, and increasing construction higher education to attract and retain professional women in the industry. The strategies suggested in this paper will help attract and retain female graduates in the Ghanaian construction industry to enable them effectively participate in infrastructure development. The barriers to female retention, the strong push factors identified and the measures suggested for female retention are of value to construction practitioners and learning institutions in Ghana and other African countries.

Sustainability of construction projects has become a major issue facing decision-makers, developers, city and urban planners as well as designers worldwide. Construction projects are characterised with the excessive use of natural resources and consumption of energy, which have a crucial impact on the environment and future generations. This called for the construction industry to adopt the Lean principles as an approach to achieve sustainability objectives. Due to its achievement, partnership between public and private sectors turned into a strategic option to promote sustainability of construction projects. The increasing recognition and apparent success of lean principles called for focusing on utilising the knowledge and skills of project participants to develop sustainable construction through enhancing values and eliminating wastes. This paper aims to investigate the role of public-private partnership (PPP) in applying Lean principles as an approach for sustainable development in construction. A research methodology is developed to accomplish four objectives. Firstly, literature review is used to build a comprehensive background about the research topic including partnership, sustainable development and lean principles. Secondly, case studies are presented to explain the role of partnership in delivering sustainable construction projects. Thirdly, developing a framework to facilitate the creation and implementation of partnership between public and private sector towards lean sustainable development in construction. Finally, summarising research conclusions and recommendations for governmental authorities, construction professionals and further research. Research findings showed that creating a partnership between the public and private sectors could play a significant role towards achieving sustainability in construction through lean principles application.

Variations in construction had been studied by a number of researchers in the light of its causes and effects on project delivery, thereby taking for granted the susceptibility of building elements to variation. Thus, this paper becomes imperative to fill the gap with a view to examining the proneness of building elements to variation and assessing the control measures of proneness of building elements to variation before and during construction process. Data were collected using structured questionnaires administered on construction professionals in Lagos metropolis. Systematic sampling technique was employed in the administration of the questionnaire to consulting firms, contracting firms and client organizations within the built environment in the study area. The data were analyzed using statistical methods of average, percentage, relative significant index (RSI) and Spearman rank-order correlation coefficient. The results of the analysis revealed that excavation and fillings, concrete work at substructure, block work at substructure, roof and wall finishes were ranked highest of the building elements that were highly susceptible to variation. While internal doors, disposal installation, water installation, ventilation system, windows and external doors respectively were less susceptible to variation during construction processes of educational building projects in Nigeria. The paper further identified involvement of professionals at initial stage of project, client's involvement at planning and design phase, clear and thorough project brief and thorough detailing of design respectively as control measures of proneness of building elements to variation. The study recommended that the identified building elements which have been known to have a high degree of susceptibility to variation are to be given utmost consideration during the design and construction process in order to minimize their effects and contributions to variation with overall aim to improving construction project delivery.

A field study of students' and teachers' thermal comfort in a school building (St. Andrews Junior High School) was carried out at Madina, Accra. The building was chosen due to the sustainable design principles (e.g. form, orientation and ventilation) employed in the design and construction of the school. The aim of the study was to investigate peoples' perception of comfort as well as examine the prevailing thermal conditions in the classrooms. Moreover, a comparative analysis of the results with the worldwide accepted ASHRAE recommendations was carried-out. The study employed the use of subjective assessments through questionnaires and physical measurements. The measured environmental parameters required the use of Hobo data sensors, these measured temperature and relative humidity values. The subjective responses concerned the occupantsâ?? judgement about their thermal environment. One significant conclusion drawn was that the classroom spaces on the ground floor experienced lower temperatures, whilst those on the first floor had a higher temperature (difference of 2°C). The first floor classrooms experienced higher thermal conditions as a result of the absence of a ceiling. In addition, though a large majority of the respondents accepted their overall thermal conditions, a number of them still voted below the standard set by ASHRAE of 80% positive votes by occupants for thermal comfort. The study also showed that respondents in tropical countries such as Ghana may have a higher heat tolerance, since most of the interviewees accepted the existing thermal conditions which exceeded the standard of between 26°C and 28°C (summer comfort range) by 1°C to 5°C.
State of public buildings in Ghana after the passage of the Persons with Disability Act (Act 715) : the case of tertiary institutionsSource: Journal of Construction Project Management and Innovation 2, pp 448 –463 (2012)More Less
Persons with disability Act (ACT 715) makes it mandatory to put up buildings that are disabled friendly but most designers and contractors in Ghana fail to factor the disabled people in the design and construction of infrastructure. In most cases where attention has been given, the provision of the person with disability has been misconstrued by some building industry players to mean provision of ramps to ground floors. After the passage of the persons with disability Act, in 2006, it has become necessary that all public buildings in Ghana have to be designed and built to incorporate the required features that will aid the disabled to have a comfortable access to all public places. This study is therefore carried out to investigate into the state of public buildings in Ghana after the passage of the persons with disability Act (ACT 715) with particular emphasis on public tertiary educational institution buildings in Ghana. To achieve the study objectives, the paper adopted research survey method which includes the use of questionnaire and interview conducted among Contractors and Clients representatives as well as officials from the Law Enforcing Agency who are directly involved in the construction of public buildings. The study considered four public tertiary institutions and the type of buildings considered under these institutions are lecture halls, studentsâ?? hostel, offices and residential flats for staff. The results showed that though the disability law has been passed, out of 31 buildings investigated, 9.68% of the buildings were fully factored with disability facilities, 67.74% partially factored and 22.58% not factored at all. The study concluded that law enforcing agency should ensure that construction professionals fully factor disabled people in their building designs and construction. Massive education should also be given to the general public and clients about the need to make buildings disabled friendly.

This paper has investigated the environmental challenges faced by Peri urban settlements in the Lagos Megacity. An intense study of the Isheri, Ibafo and Sagamu Interchange areas along the Lagos Ibadan Expressway axis was done. Socio economic characteristics, housing and environmental conditions as well as rural urban linkages were done to determine the flow of interaction between the settlements and the Lagos Metropolis. Data collection was by the administration of structured questionnaires on household heads of which 46 were sampled in Isheri, 113 in Ibafo and 191 in Sagamu Interchange areas respectively. Survey was by systematic random sampling. The study revealed a high level of interaction between the settlements and the Lagos Megacity as over 60% of respondents in the study area commute daily to work in Lagos. The study also revealed that land value, rental value in these peri-urban settlements had increase since 2005 when the highest rate of population influx was observed. Furthermore, environmental challenges especially poor infrastructure and security concerns had exacerbated. The paper concluded by suggesting strategies for mitigating these challenges and they include the introduction of participatory planning mechanisms as well as the enforcement of development control
