ENABLING STRUCTURES FOR CONSTRUCTION OF UNDERGROUND METRO CORRIDOR IN SOFT STRATA - A Case Of DMRC, New Delhi
DEBASIS SARKAR & DR. M. NAGESH
The construction of an underground corridor for metro rail needs well-designed earth retaining and supporting systems especially for cut and cover construction during excavation activities. The temporary supporting systems are designed as per the strata in which the corridor is executed. Generally, if the strata is of pure soil with minute quantities of weathered rock, then the temporary supporting systems consist of soldier piles, king piles, sheet piles, secant piles, timber lagging, steel struts and diaphragm walls. For a rocky strata, the excavated rock surfaces are stabilized by shotcreting & rock bolting. Rock anchors can be used as substitute to struts at the junction of soil & rock. All these supporting systems are removed at various stages of construction of the permanent civil structure as per the construction sequences. This paper has been dealt as a case study of Delhi Metro Corridor MC1B executed by IMCC JV.

POWER OF TRENCHLESS TECHNOLOGY IN MODERN ERA
SACHIN JAIN
In the modern era due to urbanization our need of telecommunication, power, water, sewage and transport are much higher than olden days. Thus to adopt traditional methods to do “dig-lay-cover” or “open trench” techniques in congested areas in city one would have to remove trees, and even some structures which come in the way. Also there is traffic congestion while work is in progress causing inconvenience to public. It could also harm the environment due to pollution of air and dust. Hence we need a new form of technology to solve these problems and will do the work with the least pollution to the environment, this is trench less technology.

PROSPECTS OF REPLACEMENT AND REUSE OF TIMBER IN CONSTRUCTION INDUSTRY
AR. SATYAKI SARKAR
In maintaining ecological balance and environmental stability, forests play a vital role. Infact, timber is an excellent natural composite material, which has been used by mankind since early ages for house building, agricultural implements, fuel, furniture etc. But with the decreasing forest cover of the country, the country's premier Government Construction Agency, CPWD has banned the use of wood in its construction projects way back in April 1993. The replacement and reuse of recovered solid wood since then has hogged the limelight. While the timber industry has been using wood residues from primary wood processing mills for decades, use of secondary species of timber along with the replacement and reuse of wood has become one of prime importance and has provided a much needed variety in terms of application to the construction industry.

A CRITICAL REVIEW OF MARKETING STRATEGIES AND PRACTICES OF CONTRACTING ORGANIZATIONS IN TURKISH AND NORTHERN CYPRUS CONSTRUCTION MARKETS
MEHMEDALI EGEMEN and DR. ABDULREZAK N. MOHAMED
Although marketing has been very commonly used in other industrial sectors for a long time, the ‘unique’ construction sector has not been applying marketing principles widely. This paper made a detailed critical review of the marketing strategies and practices of the contracting organizations by presenting survey findings of 80 contractor firms in Turkish and Northern Cyprus construction markets. The findings revealed that construction marketing is still in its early stages and there is still a long way to go. It is obvious from the results that marketing is still essentially understood as a sales function and any marketing activities, which are undertaken occurs mostly on an intuitive basis. Even the firms which accept the importance of marketing concept try to do marketing without assigning extra resources or budget for it, which is definitely limiting the amount of benefit the firms could have gotten from their marketing applications. The findings also reveal that larger sized companies are involved in marketing action more often than smaller sized ones. Moreover, it was concluded that a combination of the relationship marketing with the traditional marketing mix will give the best results for contracting organizations in construction markets. Although marketing planning and strategy formulation stages are assigned relatively high importance by the firms, it is found that the basis of these strategies are not defined properly due to lack of systematic approaches in marketing research. Although marketing is a dynamic process, which needs regular evaluation and updates, it seems that the contractor firms are not involved in a systematic and periodical evaluation of their strategies. Although the findings of this study are based on input from Turkish and Northern Cyprus construction markets only, we believe that the overall approach, framework and the findings this study are of good value to the organizations contracting in other construction markets throughout the world as well.
