| Summary: | This study evaluates the influence of project plans on the outcome of design-build
projects. The purpose is to ascertain whether the level of use of project plans can be utilised
to improve the outcome of projects procured by the design-build method. To achieve this
purpose, a field survey of 42 projects procured by the design-build method and selected by
stratified random sampling was conducted. Data were collected with the aid of structured
questionnaires and analysed using percentage, mean and the Spearman correlation test.
The results of the study indicate that the level of use of project plans has significant influence
on some parameters of the design-build projects' outcome. The results also indicate that the
inception, design, tendering and construction plans are not prepared in many of the projects
sampled. The study concludes that the level of use of project plans can be used to reduce
the high time and cost overruns recorded in design-build projects and that there is room for
stakeholders to increase the level of use of project plans in design-build projects. The study
suggests that stakeholders should ensure that the required project plans are prepared when
projects are procured by design-build.
