INFORMATION TECHNOLOGY IN THE CONSTRUCTION INDUSTRY

MILIEU OF THE PROBLEM

Construction is one of the largest industries in the world and one of the most disjointed as well. One of the reasons why the industry is so fragmented is that the construction industry involves parties from myriad professions. Different types of information are exchanged between the various parties for the purpose of communicating design, construction and contractual matters. Individual firms have developed their own means of classifying and disseminating procurement and cost information to facilitate the process. However, as there is no standardised system of classifying and sharing of such information, data is lost along the way. Proper planning to eliminate conflict, duplication and omission in the distribution of procurement and cost information is lacking, and this can be ascribed to the fact that modern information technology has not fully penetrated the industry. Many professionals and contractors still use old-fashioned paper-based methods of exchanging information, making communication slow and inefficient. Advanced and cost-efficient communication technology, based on a nationally accepted and internationally compatible standard, should assist in making the construction industry a more powerful and streamlined machine. This will allow professionals and contractors to collaborate more effectively with partners, staff, building owners, manufacturers, designers, etc on both the local and international levels.

TERMS AND DEFINITIONS

Bills of Quantities: A document drawn up by a quantity surveyor, usually in a standard format, for purposes of tendering, payment and final account. It comprises a descriptive list of all the items of work required to construct a particular building or buildings and descriptions of the materials, workmanship and other matters, such as the nature of the building site, conditions under which the construction work has to be performed, etc. These items are measured from the drawings issued by the architect or engineer(s) and from information supplied in specifications that have been prepared by the architect, engineer(s) and other specialists appointed on the project.

RESEARCH OBJECTIVES

The primary objective of this research study is to improve the effectiveness of producing quality and up-to-date procurement documentation for the construction industry, and to cause the achievement thereof in the shortest possible time. This research study will endeavour to illustrate the point that what is currently on offer in the RSA with regard to the procurement process falls far short of the local construction industry‘s requirements. Possible actions to be undertaken by the local construction industry to overcome these shortcomings will be investigated, with particular emphasis on establishing national standards for classification and specification systems that are modern, internationally compatible and suitable to accommodate present and future needs.

Interviews
At the initial stage of the research process (after the preliminary literature review), it was decided that it would be beneficial to investigate the development of classification systems for construction information elsewhere in the world, as very little development on this issue had taken place in the RSA.
