The objective of management system for storm water is essentially to safeguard health, safety and property of the citizens/ residents and to reduce inconvenience to them by having an integrated approach for developing and maintaining a system for storm water runoff which will provide better quality of life for the society. The effect of urban development has increased flood frequencies in areas due to imperviousness. In storm water management system, urban runoff estimation plays important role in the design of storm water drainage system. Hence considerable emphasis should be given to the accuracy of urban runoff quantification for developing efficient drainage systems. Mumbai city experienced the unpredicted rainfall of 944.2 mm in 24 hours on 26th July 2005. Extensive floods were experienced in low lying areas such as Milan subway. The area selected for the case study was Milan subway at western suburb of Mumbai which is the chronic flooding spot for so many years. Due to the flooding problem, it is very inconvenient to the vehicular traffic as well as to the pedestrians. The existing drainage system is inadequate to mitigate the flooding problem at Milan subway. This paper aims to design the management system for storm water at Milan subway in such way that the floods are avoided. This paper presents detailed hydrologic analysis carried out to study the flooding situation at Milan subway under various rainfall intensities. The drainage system options are suggested so that floods are avoided and water is conserved and thus the need of urban community against the safety of property and health of humans, animals from floods, flowing streams can be achieved.

A COMPARATIVE STUDY OF LEED-NC, U. S AND LEED-NC, INDIA FOR GREEN BUILDING APPROVAL
J.E.M. Macwan, Rajiv Bhatt and Darshana Bhatt
LEED INDIA for New Constructions, version 1 rating system is a voluntary, consensus-based standard for developing high performance and sustainable building, which is implemented in our country for the approval of Green building by Indian Green Building Council. In this paper, an attempt has been made to compare it with LEEDNC, version 2.2 used currently by United States for the certification of Green buildings in U.S. In the end, few recommendations are given for further improvement and a scope is identified for the researchers to go for further refinement of the existing LEED-NC INDIA to propagate and make the green building movement more market driven.

GROWTH STRATEGIES : A NEED FOR CONSTRUCTION FIRMS IN INDIA
SANJAY BHATTACHARYA, K.C. IYER AND DR. K. MOMAYA
Attitude of an individual is formed out of feelings and perceptions. The feelings are revealed in terms of the importance one attaches to various components or attributes of the object. The perceptions are expressed by way of the level-of-satisfaction one derives from the same. Most of the studies referred have covered three alternatives, viz auto, public transport and car pool. No attempts have been made to study a situation similar to Indian cities where a large number of modes compete to share travel trips. The rank ordering of various attributes according to importance can give only broad indications for planners to decide what aspects need more attention than others to improve transport systems. Such studies call for finer divisions and definitions of various modal attributes for eliciting opinion. Time and cost involved in obtaining such information in a heterogeneous community using household survey techniques would be too high. In a situation, where the choice alternatives are 5 to 6 as in Indian conditions, the segmentation technique becomes difficult to operate calling for large computational work. Development of multiple Linear Regression (MLR) or Multi-Nominal Logit model using attitude scores as variables along with other variables may give better results and this can be used to forecast choice of commuters in multimodal environment.

THE DEVELOPMENT OF RESOURCE-DRIVEN SCHEDULING MODEL FOR MASS HOUSING CONSTRUCTION PROJECTS
A. CINDRELA DEVI AND K. ANANTHANARAYANAN
Resource continuity is the key issue for Mass housing construction projects, which is repetitive in nature. Resources are therefore being deployed repeatedly for the similar or identical tasks in these projects. In order to eradicate delays in mobilizing resources, an efficient resource schedule is required. Traditional scheduling tools like Critical Path Method (CPM), Programme Evaluation and Review Technique (PERT) are less effective in scheduling repetitive construction projects, as they consider availability of resources are unlimited. The main challenge in preparing construction schedule for repetitive projects is synchronizing the precedence logic and the allocation of resources as per requirements for all the activities. Consequently, activity scheduling and resource planning are prepared in parallel and this will facilitate in eliminating delays and idle resources across the projects thereby, controls the chain-reaction management (ripple effects). Nevertheless, almost all the repetitive scheduling methods developed so far have been giving focus on continuous repetitive projects, whereas in the present study, the emphasis is on discrete (non-linear) repetitive projects. This report presents a model that uses genetic algorithms to optimally assign resources to repetitive activities, which aimed to minimize the total project cost & duration, idle cost & time and to maximize resource utilization. In the present study, an attempt is made to generate a resource-driven construction schedule automatically, with which resources can optimally be allocated to the activities. This schedule can be very useful in improving productivity and saving construction time and cost and also in decision-making. The model has been validated through a case study to check the efficiency and effectiveness of the resource-driven construction schedule.
ANALYSIS OF DEMOGRAPHIC PROFILE AND PREFERENCES OF PUNE’S PROPERTY BUYERS – A SUPPLY SIDE PERSPECTIVE OF PROPERTY DEVELOPMENT FIRMS
DR. MONA N. SHAH
The housing and commercial property market in Pune has been growing consistently over the last decade. The property development firms would be naturally inclined to serve the potential market better. Therefore, firms adopt marketing strategies at the functional and operational level in order to attract customers to their projects. Marketing strategies begin with an understanding of customer needs and wants, segmenting, targetting and positioning, and formulate suitable market offering. A supply side analysis is done following the data collected from 121 marketing executives of real estate development firms in Pune to find out the marketing strategies adopted by the firms. Results were analysed to understand buyer preferences and related market offerings from the developers. Further correlation analysis using SPSS was carried out, to find out which amenities according to the executives were most desired by the buyers and included in the projects by the real estate developers.
