    An evaluation of the available methods of selecting a contractor, in order to satisfy the client's objectives, with a view to offering a systematic approach to which method should be adopted
    (1986) Stevenson, Colin; Butt, P E
    Although the client's objectives of balancing cost, time and performance have not changed, the complexity of the design and construction of modern buildings today requires a thorough understanding of the factors affecting these objectives if they are to be accomplished. This study therefore begins by analysing the client's objectives to establish the factors affecting each objective and to determine the inter-relationship and possible conflict between these factors. The principal types of contracts and methods of selecting a contractor are then identified. The methods of selecting a contractor are then evaluated according to these factors and their effects on the client's objectives are established. This evaluation is then used as the basis for recommending a procedure to choose which method should be used to select a contractor, in order to accomplish the client's objectives, under differing circumstances.

    A review of construction work sampling methods and an investigation into their use in South Africa
    (1987) Hund, Peter J; Poole, C W
    Work sampling had its origin in industrial engineering; however, its use in construction has increased greatly during the 1970's and 1980's. Research would suggest that most of the innovation in this field is taking place in the United States. The basic methods of Work Sampling have been developed to suit the peculiarities of the construction site as opposed to the production line or factory where it was first used. The objectives of this report are as follows: 1. To review the existing methods of Construction Work Sampling as well as discuss further aspects and problems which should be considered when undertaking a Work Sampling study. 2. To compare Construction Work Sampling with other methods of measuring productivity. 3. To evaluate by means of a case study the ease of applicability of the sampling methods to a South African construction site, and at the same time to identify differences between the description of the methods in theory and their use in practice. 4. To establish by means of a questionnaire the extent to which Construction Work Sampling methods are already in use in South Africa as well as other related information. Information for this report was obtained from journals, manuals, text books, interviews, and the case study and questionnaires mentioned.
