QUALITY CONTROL IN CONSTRUCTION USING NON-DESTRUCTIVE TECHNOLOGY

The strength of the given concrete depends on its age and the temperature at which it is cured. Maturity method uses this well-known fact to estimate the concrete strength in its early age. Maturity is defined as the integral of time and temperature of concrete above the datum temperature. A common means of strength prediction is the maturity method. This method uses an empirical base to relate the time-temperature profile of a particular mix design to its strength at early-ages. As there is need for in-situ monitoring of structural strength, this technique helps to measure the strength at the place of construction, thereby ensuring quality control at sites. In the present article this method is discussed with its theoretical background and its application.

PLANNING FOR ITERATIVE DESIGN PROJECTS USING DSM@IITM
J. UMA MAHESWARI
DR. KOSHY VARGHESE
Design is a process of information exchange between various domains and is usually iterative in nature. In a network representation, the iterative relationships are modelled as cyclic dependencies between activities. Conventional planning tools such as CPM (Critical Path Method)/PERT (Program Evaluation and Review Technique) cannot model these cyclic dependencies. Advanced graph based tools which can model cycles/loops too have practical limitations. Researchers have identified DSM (Design/Dependency Structure Matrix) this potential tool for planning design iterations. Using this matrix representation, information dependencies can be organized and analyzed in a structured manner to identify and evaluate sequences for execution. The available DSM software for construction has focused mainly on the planning aspects. Hence, the objective of this paper is to develop new DSM software for project planning and scheduling. This paper illustrates the features of the software tool DSM@IITM, with an example, and also discusses the shortcomings and future directions of the tool.

QUALITY MANAGEMENT SYSTEM FOR PROPERTY DEVELOPERS
NINAD SHAH
MANISH DAVE
This paper is directed towards preparing guidelines to help property developer organizations develop a Quality Management System (QMS). Following a literature review, primary data includes six case studies. A questionnaire is used as the research tool. Based on inferences obtained from data analysis and ISO 9001:2000 clauses, various elements of QMS are developed for an assumed organization structure. The organization structure is for a small organization which generally exists in a developer’s firm. This QMS can be adopted by organizations after making case specific changes i.e. expanding as per specific functions and prevalent practices. The guidelines, give business specific applications of all the ISO 9001: 2000 clauses, in addition to their more general applications. The intent is to give a ‘ready reference’ developer organizations that are in the process of developing a Quality Managment System (QMS) or those that would like to develop one in the future.
