Contributors to schedule delays in public construction projects in Saudi Arabia : owners' perspectiveAuthor Ibrahim MahamidSource: Journal of Construction Project Management and Innovation 3, pp 608 –619 (2013)More Less
This study aims at identifying the contributors to delays in public construction projects in Saudi Arabia from owners' viewpoint. To do so, 22 public owners of construction projects completed a structured questionnaire survey. 35 factors were identified through literature review. The results indicated that the top delay contributors are: bid award for lowest price, poor site management, poor communication and coordination between construction parties, payments delay, poor labor productivity, and rework. These findings can support the Government in improving the regulations to meet the construction market needs, owners in planning and designing and evaluating policy, contractors and managers in planning and taking external and internal risks when costing and scheduling contracts, consultants in applying comprehensive contract information, and workers in conducting their day-to-day activities. Results will fill an important research and practice gap and help in improving time performance in public construction projects in Saudi Arabia and other developing countries.
Determining the effectiveness of concurrent engineering through the analytical hierarchy processing of project success criteriaSource: Journal of Construction Project Management and Innovation 3, pp 620 –639 (2013)More Less
The emergence of Concurrent Engineering (CE) as the Project Procurement method of choice for effective integration and coordination into construction has been gaining grounds. However, this is based mainly on empirical data that were derived majorly from the implementation of CE within the manufacturing environment. Thus the theoretical foundations of CE has been more empirical that statistical. Although science is driven by data, strong theoretical foundations must exist in order to explain that data. This work seeks to confirm statistically, the prominence of concurrent engineering as the method which offers the most scope for effective attainment of construction objectives of Cost, Time, Quality and Clients Satisfaction. Using the Analytical Hierarchy Process (AHP) model, these project success criteria were used as the primary criteria, along with its sub-criteria, to calculate the Eigen-vectors, in order to synthesize a pair-wise comparison matrix of the criteria. Thus the priority weight vectors were obtained and used for the ranking of the four principal construction delivery methods: Traditional method, the Design and Build method, the Programme management method and the Concurrent Engineering method. The results of the data computations gave a ranking of the four (4) principal project delivery methods of; Traditional sequential delivery, Programme management, Design and build and CE, with the values 0.0001, 0.1027, 0.2062 and 0.6910 respectively. CE ranked highest in its effectiveness in attaining construction goals. The work thus confirm statistically, the prominence of concurrent engineering as the method which offers the most scope for effective attainment of construction objectives of Cost, Time, Quality and Clients Satisfaction.

The study assessed the level of compliance of construction professionals to ethical practices in the Nigerian construction industry. The study area was Lagos State and the target respondents were the registered professionals including architects, quantity surveyors, builders and engineers. A total of one hundred and seventy (170) questionnaire were randomly administered on the professionals and one hundred and thirty eight (138) were retrieved representing 81.18% response rate. Findings revealed that professionals displayed high level of compliance to clients service delivery with Mean Item Score (MIS) ranged 3.22 to 3.79, educational and professional qualification MIS ranged 3.18 to 3.71 and standards of practice MIS ranged 3.16 to 3.63. The overall rating revealed that professionals have highest level of compliance to standards of practice with 54.76%, while the least ranked ethical standards was fair compensation with 49.31%. ANOVA test established a statistical significant difference among the professionals view about compliance of the professionals to clients service delivery (F value=2.447, P value=0.020) and professional development (F value=3.774, P value = 0.001). The overall level of compliance of construction professionals to ethical standards was 52.37%. The study concluded that professionals have average level of compliance to the ethical standards. The study therefore recommended that professionals should continue to uphold good ethical conducts, for better project performance and delivery in the Nigerian construction industry.

Knowledge management is a developing area in the construction industry that can contribute immensely to the success of any organisation. This research work therefore examined the areas of the construction industry that will improve as a result of the contributions of knowledge management. Data for the analysis were collected through questionnaires administered on construction professionals using convenient sampling method. The data were analyzed using percentiles and mean item score. The study revealed that the knowledge management adoption is being hindered the most in Nigeria by funding as there is no adequate fund to carry it out in construction organizations. Assessment of the level of sharing knowledge among construction professionals showed that Architects ranked first in sharing knowledge with other construction professionals while top managers, Quantity surveyors, Estate Surveyors, and Civil Engineers followed respectively. In conclusion, it was observed that colleague's experience was ranked first among the sources of knowledge available to construction professionals in Nigeria as most construction professionals in Nigeria don't read much and are not exposed to other methods of acquiring knowledge within the organisation, and fund is the highest ranked problem hindering the adoption of knowledge management among Construction Professionals. It was then recommended that Civil Engineers, Builders, Middle managers, Lower managers and Technicians should improve in the level at which they transfer and share knowledge with other construction professionals and that the Federal Government of Nigeria should inject more fund to the construction industry of the country as this is a very productive sector of the economy.
Towards a systemic construction industry development : a research agenda for a fragmented industry in AfricaAuthor Williams Gyadu-AsieduSource: Journal of Construction Project Management and Innovation 3, pp 680 –696 (2013)More Less
In spite of the several attempts by African countries to address their infrastructure needs, and despite the enormous investments injected into infrastructural development, much has not been achieved. The central problem is that researches and development issues in the industry have not taken into consideration its fragmented nature and how this impacts on the efforts being put in place. Relying on the survey of literature review, this paper proposes a research agenda for the construction industries in Africa and other developing countries in which a concerted effort based on systemic approach should be used to address the problem. It is conceived that the research and development objective of the industry in Africa could be better achieved if it is considered as a system of fragmented components. This will provide a framework in which the General Systems Theory which will enable the application of laws and theories from other disciplines in the industry's research and hence its development. The expected results is that improvements and developments programmes shall be focused on individual component parts whose interactions, if properly managed, will result in the development of the whole. In the process better and realistic results of infrastructural developmental agenda will be achieved.
