    The calculation of acceleration costs on construction projects
    (University of the Free State, 2009) Maritz, Tinus; Schutte, Andries
    English: A lack of understanding often exists between contractors, client organisations and consultants as to what may, and what may not, be included in acceleration claims on construction projects. The aim of this article is to create a better understanding of the complexity of acceleration claims. It should also lead to new insights into claim procedures and the substantiation of acceleration costs. The impacts and delays which may result in acceleration claims on a project were analysed as they form the basis for establishing liability in terms of a particular contract. Matters of principle that are applicable to acceleration claims, regardless of the form of contract recommended for use in the South African construction industry, were also examined. The findings indicate that there are significant differences on a number of aspects regarding the calculation of acceleration costs on construction projects between contractors, consultants and employers/developers. The majority of the respondents, however, were of the opinion that of the various methods used for calculating acceleration costs, the time impact analysis is most frequently applied, but that the modified total cost approach is the method most suitable on projects where there is a significant increase in the scope of work, something that occurs regularly on construction projects.

    Client attitude to health and safety – a report on contractor’s perceptions
    (University of the Free State, 2009) Musonda, Innocent; Haupt, Theo; Smallwood, John
    English: The purpose of this article is to present findings of a preliminary survey on contractors’ perceptions of clients’ attitude relative to health and safety (H&S) implementation in the construction industry of Botswana and Southern Africa. A questionnaire survey was conducted on construction projects to establish clients’ attitude towards H&S. Interviews were also held with contractors’ representatives on selected construction sites in and around Gaborone, Botswana. Findings from the survey include: clients do not perceive H&S to be very important on construction projects; the majority of clients do not address H&S adequately in contract documentation, and H&S is rarely a major item on the agenda of progress meetings. Findings also included that clients are not fully committed to H&S implementation. The client sets the tone for H&S culture. Client attitude is therefore very important for H&S performance improvement as all stakeholders are compelled to act in line with the client’s values. Various researchers have recognised the importance of the client to H&S performance improvement. The extent to which clients are involved in H&S implementation has, however, not been researched extensively, especially in Southern Africa. This article therefore provides an insight into the clients’ attitude towards H&S and explains the reason for the current state of H&S in Botswana’s construction industry.

    Managing risks associated with the JBCC (principal building agreement) from the South African contractor’s perspective
    (University of the Free State, 2009) Othman, Ayman; Harinarain, Nishani
    English: Construction is a complex and risky business. It is a time-consuming process involving a multitude of organisations with different objectives and skills. In addition, increasing client expectations coupled with the technological development of materials and equipment made the construction industry subject to more risks than any other industry. Contracts are essential tools for organising the relationship between involved parties and managing associated risk. For years the South African construction industry had a very poor reputation in managing construction risks. In order to improve the image of the South African construction industry and to assist contractors to develop their proper risk management strategy, this article aims to manage the risks associated with the Joint Building Contracts Committees (JBCC) Principal Building Agreement (PBA). A research methodology, consisting of literature review, questionnaires and interviews, is designed to achieve four objectives. First, to review the topics of contacts and risks in construction projects and the JBCC (PBA). Secondly, to develop an innovative framework to enable contractors to identify, quantify and classify risks associated with the JBCC (PBA). Thirdly, to evaluate the developed framework from industry’s feedback in order to improve its performance. Finally, to create a correlation matrix of contractor’s risk sources.
