There were numerous complaints regarding the quality of building projects performed by the Department of Building and Engineering Services (DBES) in Botswana. This empirical study has two objectives: first, to evaluate participants in DBES projects by using 16 identified factors in the project design phase that may influence the quality of building projects; second, to explore the inter-relationships between the 16 factors in the project design phase and the five measures of which the design phase takes cognisance. The study applied a quantitative research methodology. A total of 115 survey questionnaires were distributed to collect data. A descriptive and a multivariate analysis was performed.


In Botswana was daar verskeie klagtes ontvang aangaande die kwaliteit van bouprojekte soos uitgevoer deur die Departement van Bou- en Ingenieursdienste (DBES) in Botswana. Twee doelwitte is vir hierdie studie gestel: Eerstens om deelnemers in DBES projekte te evalueer aan die hand van 16 geïdentifiseerde faktore ten opsigte van die kwaliteit van bouprojekte tydens die ontwerpfase van hierdie projekte; en tweedens om die verwantskap te ondersoek tussen die 16 faktore in die ontwerpfase van bouprojekte en die vyf maatstawwe wat tydens die ontwerpfase in aanmerking geneem word. 'n Kwantitatiewe navorsingsmetodiek is tydens hierdie studie gebruik, waar 'n totaal van 115 vraelyste uitgestuur is. 'n Beskrywende en meerveranderlike analise is uitgevoer.
