A framework for planning and analyzing contractual practices in underground construction - The basis for a contractual database

摘要

The paper reviews some of the key problems encountered in endeavouring to develop a model for fair contractual practices in underground construction. Over the last 30 years members of the ITA WG 3 - contractual practices have developed a series of proposals for good practice with individual supporting position papers on each subject handled. As a result of the review it became apparent that it would be necessary to provide a framework which could visualize the relationships between parties, their responsibilities, rights and obligations. This was principally due to the wide variety of different contractual practices that are employed world wide and the new forms of contract that have been employed over recent years. The paper demonstrates the relationship between the framework and the individual proposals which can be used for illustrating all forms of contract both past and present, as well as demonstrating the areas of concern for future research and development. An attempt has been made to present the information in a modern user friendly colour coded format, in response to the key questions: where?, who?, what?, when?, if?, how?, how much?, whether?, why?, etc. and a decimal system which lends itself for establishing a relational database that can be easily adapted for use on the internet.
