Different indices are encountered in the building industry for use by built environment professionals, such as input-price indices, output-price indices and seller's-price indices. Currently there is only one tender-price index (or output-price index) that is published on a regular basis in South Africa, through the University of Stellenbosch Bureau of Economic Research (BER) building cost index. This article is based on information gathered from two questionnaire surveys conducted among quantity surveyors in South Africa regarding their perception of tender-price indices (TPI) in South Africa. The research findings indicate that a TPI is an important tool for use by quantity surveying practices. One of the problems related to the accuracy of the BER index is the lack of information provided by quantity surveying practices. A suggested remedy for this problem can be the involvement of the ASAQS. There may be room for a new, alternative TPI, based on recent information, in the South African building industry.

While rapidity in service activities have strengthened the role of urban areas as engines of economic growth, high population density and increased industrialization, has brought needless social and environmental complaints in cities. This phenomenon necessitates a change in societal attitude in favor of the creation of responsible living conditions, which demands requisite skills and knowledge that would shape the cities. Thus, this paper explores the adequacy of current urban engineering education in terms of the knowledge, skills and competencies required to plan and develop future cities. The paper examines how "wicked problems" that marginalize effective sustainable city planning can be addressed through astute understanding of social and environmental challenges, urban governance systems and stakeholder involvement. Based on current education system, initial findings suggest that competencies in urban planning will not necessarily enable students to address challenges related to the development of smart and sustainable cities. Rather, engineering, science and social knowledge, which would engender the ability to predict future social dynamics, should enable graduates to become active drivers of sustainable and livable cities.
Significant waste factors influencing delivery cost performance of design and build low-cost housing projects in Imo State NigeriaSource: Journal of Construction Project Management and Innovation 5, pp 1152 –1175 (2015)More Less
Effective performances particularly on low-cost housing projects has been a major problem in many developing countries. In Nigeria, public sector clients have adopted the design and build (DB) procurement strategy as one of the strategies to deliver Low-cost housing (LcH) projects following potential benefits to facilitate improved performances particularly as it pertains to project cost. Yet, many design and build low-cost housing (DBLcH) projects are not delivered within expected target cost performances resulting from the influences of waste factors amongst several others identified. This paper aim to identify the waste factors that significantly influence poor cost performances of DBLcH projects based on the investigation of the LcH sector in Imo State Nigeria. A mixed method design, using literature review and survey questionnaire, was adopted in this study, to identify and validate contextual waste factors influencing DBLcH project cost performances. Findings revealed the significant waste factors influencing poor cost performances of DBLcH projects. This study's findings is expected to increase the awareness of the project team on the significant waste factors that will need to be mitigated towards improving the cost performances of DBLcH projects in Imo State Nigeria.
An empirical assessment of ineffective communication inherent in the attributes of mass housing projectsSource: Journal of Construction Project Management and Innovation 5, pp 1176 –1195 (2015)More Less
Mass housing projects (MHPs) continue to experience significant communication difficulties among the project teams in their delivery which is largely perceived to be due to the influence of its unique characteristics. However, what is less known is the extent and nature of the communication problems caused by the unique features of MHPs. Through a structured questionnaire survey, empirical data were drawn from mass housing project team leaders of real estate organizations who have been actively involved in the execution of mass housing projects in Ghana. The crux of the survey was to identify the communication ineffectiveness among the project team that are inherent in the unique features of MHPs. Through the use of factors analysis as the analytical approach, three underlying clusters named in order of their significance as component 1: Access to information challenges, component 2: Challenges in flow of information and component 3: Import of information challenges were identified as the main communication ineffectiveness inherent in the unique features of MHPs experienced among the project team. These findings provide the necessary foundation towards planning and formulating communication strategies as well as developing behavioural skills needed to engender communication effectiveness in mass housing delivery. The findings 'misunderstanding' and lack of defined roles' emerging as communication ineffectiveness peculiar to MHPs also reinforce the uniqueness of mass housing projects compared to traditional construction building projects and thus useful for practitioners to gain insight into the project attributes and management intuition on MHPs.
Eliminating enforced idleness of resources and job waiting time in time-constrained construction activities using waiting line theoryAuthor Oluseye OlugboyegaSource: Journal of Construction Project Management and Innovation 5, pp 1196 –1210 (2015)More Less
Waiting of labour on construction site is a waste of energy and has been described as a shortcoming and production waste that can affect work performance and profitability of contractors. Labours are expected to be flowing through the construction site and not to be stationary; but when activities are not well-designed, their capacities are withheld and are forced to be idle. Also, conventional job-design techniques focus on planning of operations and required operatives without considering the elimination of waste related to operatives. Hence, this study explored the application of waiting line theory to eliminating the cost of waiting time of resources using the construction of a hypothetical upper floor slab. The practical application of waiting line theory was demonstrated and conclusions were drawn from the findings of the study. The findings revealed that waiting line theory can be applied in the design of time-constrained construction activities so as to eliminate enforced idleness on construction sites through reduction in the waiting time of resources.

Quantity surveying profession has changed over time to adapt to the changing and increasing requirements of project owners. In the year 2007 to 2011, the construction industry experienced economic downturn causing uncertainty in the profession. This study examined the developmental trend of the quantity surveying profession in the construction industry to determine its future. The independent variable was the current level of satisfaction of quantity surveyors while the dependent variable was the future growth of the profession. The working hypothesis was that the profession would experience future growth. A survey questionnaire via Qualtrics online survey software was administered to quantity surveyors to determine their opinion of the profession. Data collected were analyzed using SAS v9.4 statistical analysis software. The results showed a greater level of satisfaction of quantity surveyors with the current developments in the profession. Further, the current level of satisfaction with the profession strongly correlated with the chances of growth of the profession, implying a greater likelihood of future growth in the roles of quantity surveyors in the next 10-15 years. Areas such as information technology and sustainable construction would favor the growth. Thus, the hypothesis was supported. Another finding was that females tended to be fewer in the profession. Thus, it was recommended that further research be conducted focusing on gender equality and propose ways to encourage women to join the quantity surveying profession. Overall, the study concluded that quantity surveyors should improve and diversify their roles more to provide greater value to project owners as the profession seemed promising.

In South Africa, construction projects still experience non-conformance to quality requirements as well as cost and schedule overruns to the detriment of clients. For project success to be attained, conformance to these parameters is the minimum expectation in the face of other considerations related to client satisfaction. Thus, through the use of existing literature, and a field study conducted among site management employees working for general contractors (GCs) in the Eastern Cape province of South Africa, the management of quality on construction sites was examined. The study that was descriptive in nature shows that lack of skilled general workers and artisans contribute to poor quality control and management processes; while defects and rework form the main reason for project quality deviations on the sampled sites. The quality deviations in turn influence the level of cost and time overrun experienced on construction projects. The study corroborates the literature reviewed in that there is an interrelationship between cost, quality, and time in South African construction. For example, when the quality of work is below the required threshold, it leads to cost and time overruns due to rework that requires extra effort and expense. The value of this explorative study is that both site management and workers should be hands-on in terms of managing quality on project sites as failure to do so could have a domino effect relative to other project considerations.

A survey was conducted among cyclists in the city of Calgary, Canada, to identify the characteristics of winter cyclists in a metropolitan area with a very cold climate, and to investigate what variables are most likely to affect their cycling behavior. The findings of the survey reveal that even very low temperatures do not appear to be a major concern for most participants. Instead, the majority of cyclists mentioned road surface conditions, rather than the weather itself, to be the major deterrent to winter cycling. In order to analyze the direct and indirect relationships between the different variables affecting winter cycling, a multi-layered model was developed. The model distinguishes between the cyclists' inherent characteristics, cycling behavior variables and motivating factors that could both affect cycling behavior and be affected by inherent characteristics. Since the cyclists' inherent characteristics, such as age and gender, cannot be changed, identifying and addressing the cyclists' motivating factors could be a key to influencing cycling behavior.
Using system dynamics modelling principles to resolve problems of rework in construction projects in NigeriaSource: Journal of Construction Project Management and Innovation 5, pp 1266 –1295 (2015)More Less
Rework in construction projects has brought in two major challenges: cost overruns and delay. In this regards a study was conducted by considering various construction projects in the South West part of Nigeria to understand the causes of rework and the interventions to mitigate it. Survey research methodologies followed by the conceptual system dynamics (SD) modelling were used in the analysis. This study identified the sources of rework in construction projects from the design related, the client related and the contractor related issues and attempted to derive policy/strategic interventions to limit or eliminate rework on construction projects and its delivery by using conceptual SD models based on the influence of the variables on rework. The findings include that inappropriate scheduling for time pressure or delay at the planning stage, lack of adherence to the specifications, and non-availability of skilled human resource are the major causes of rework. However, rework in construction projects would be reduced or eliminated through policy interventions, such as, achieving client satisfaction with scheduling for time pressure or delay at the planning stage, adherence to specifications ensuring quality of work resulting in client satisfaction, and the availability of skilled manpower ensuring quality management.
Managing construction stakeholders for effective project delivery : a case of consultant quantity surveyorsSource: Journal of Construction Project Management and Innovation 5, pp 1296 –1309 (2015)More Less
Meeting stakeholders' needs and satisfaction is a primary project success factor in addition to cost, time and quality. Though studies have suggested stakeholders' dissatisfaction with project success, however, there is lack of studies on quantity surveyors' role and management in developing countries in achieving project success. This paper explored and evaluated quantity surveyor's consultant's management approach as part of a broader study aimed at 'Developing sustainable stakeholder management framework for construction projects in Ghana'. Firstly, literature on construction stakeholder management from journals and published dissertations were reviewed. Whilst, GETFund tertiary education projects in Ghana were used as case study for the research. Data was analysed using the stakeholder circle, salience and matrix approaches suggested by scholars and used in similar researches to identify and evaluate key stakeholders role and management. The study confirmed the identification and role of Quantity Surveyors as key stakeholders,though not managed as such by project managers. Project failures was also establish the an effect of stakeholder management absence and recommends the education, consideration of stakeholder management by project managers, keeping Quantity Surveyors well informed, monitored and actively involved in the project planning.
