Improvement of performance has become ever more critical to construction project success and has been subject to a considerable amount of research and attention over the past two decades. In this regard, the Saudi Ministry of Interior (SMoI) has adopted a new approach - Standard Design Model (SDM) - for the development of its construction programme to successfully manage its complex project portfolio and improve project performance. The SMoI-SDM approach is based on the standardisation of design, material specifications, contract documents and processes. It is anticipated that many lessons will be learnt due to the re-use of SDMs for future projects as well as sharing learning between on-going projects, thus leading to continuous project performance improvement. The aim of this research is to develop a framework for improving the performance of SDMs in SMoI projects. A qualitative case study approach was adopted to provide an in-depth insight into the current performance of SDM projects and identify critical success factors (CSFs) affecting the process of improvement of SDMs project performance. Four case studies were selected involving two on-going and two completed projects. Three key themes were identified from the case studies analysis; these are: adaptability of SDMs to context; contract management; and construction management. Consequently, a framework was developed to improve SDM projects performance as well as the expected performance improvement curve that results from the cumulative learning and experience. The framework validation was conducted through a workshop involving the same stakeholders who participated in the case studies, in which the feedback on possible improvements to the framework was obtained. The framework demonstrated its practicality, clarity and appropriateness for use across the SDM projects.Significantly, this research has the potential to direct standardisation of design and process in construction projects in particular in the public sector and could help achieve a sustained project performance improvement in the Saudi construction industry.

The primary goal of this research is to provide quantitative information used for the implementation of project management attributes. Nineteen project management attributes and five project performance outcomes were investigated to examine their relationships. A series of statistical analyses were conducted to quantify the relationships between the implementation levels of the attributes and the probabilities for better project performance. The analyses utilized data from 212 projects collected by the Construction Industry Institute (CII) Benchmarking and Metric database from 2007 through 2010. The results showed that the beneficial effects of project management attributes varied depending on the implementation levels of project management attributes, the performance outcome type, and whether the project was conducted by the owner or contractor organization. Quantified analysis results were provided by this research. Project management attributes were identified as critical if they were found to be significantly related to a particular performance outcome. Minimum implementation levels were provided for these critical attributes, as were results covering the combined effects of the critical attributes on performance outcomes. Based on the analysis results, the research generated specific and quantitative information used in implementing project management attributes for better performance. This information will help practitioners achieve improved project performance in the most effective and efficient way, and thus it is the practical contribution of this research. From an academic point of view, this study designed a data analysis process by a series of statistical analysis methods which makes it possible to examine the relationships between project management attributes and various project performance outcomes in a quantitative manner. / text
