Abstract: It has been claimed that civil engineering construction has done more for the preservation of human life than has all of medical practice. Provision of effective sewerage system perhaps is the single largest development in modern world, where metropolitan cities such as London, New York and Hong Kong can be built without the spread of disease. In order to maintain an effective & efficient drainage network system with daily upgrades to suit the modern development, an integrated interoperable update record system for both design and maintenance will be necessary. However, practical situation may be different in some areas of the world. For example in Hong Kong, the drainage records may not be completed in one way or the other because of historical reasons. The exact location of an existing manhole/pipeline of the network system is not correlated to the existing records after years of development. Hence the design and maintenance of an integrated drainage network system will become important. Also, the management of a sewerage information system both on site and in record becomes an important factor in civil engineering design and construction. Well with the advance of modern technology such as the use of computers for aided design, stored records, and real time response to large data operations, the situation has been improved but not to the desire level. The recent popularity of internet application of personal computers has in fact led to an ideal solution GIS is characterised by spatial analysis, scientific investigation, resource management, development planning and cartographic mapping. These are certainly the potential main streams of GIS which means easier integration of information with other existing systems. It translates into higher levels of productivity and better service via different software and hardware such as the development of this Sewerage Information System using Autodesk MapGuide for supporting excavation permit application. All these higher levels functions and services rely on the accuracy of successful transformation of raw data through different methods of analysis. This is the main reason why management problems in civil engineering construction are considered in this GIS application as engineers are also practitioners. The theme of this research will focus on the evaluation and performance of GIS application for drainage/sewerage information system on the web site. These shall include the evaluation of database linking mechanism, spatial data input or conversion method, programming techniques, and server file format. It then proceeds to create a prototype GIS on a web server with a browser, test the performance of the prototype and discuss the methods of improving the performance through this GIS implementation. It is therefore hoped that through the research of this topic, an integrated, interoperable drainage/sewerage information system with total solution can be achieved. The combination of innovative internet, intranet, mobile, and wireless technologies will provide a seamless integrated design. Documentation tasks with large data sets, multiple maps, and resulting multiple users collaboration in real time might be achieved, regardless of whether this is the client, the customers or the extended design team, anywhere on the earth. Although this small scale application of GIS approach is somewhat like the DOS is to Windows in size, the use of GIS application in Sewerage Information System is certainly a new challenge towards engineering management, hopefully this can create a new era for engineering design and quality management.
