FACTOR ANALYSIS ON THE COMMUNICATION PERFORMANCE BETWEEN PROJECT PARTICIPANTS AT THE CONSTRUCTION STAGE
Y. LIU
L. Y. SHEN
Effective communication between project participants is important to success of construction projects which involve multi-organizational team who need large amounts of information from others. Twenty-five critical success factors influencing communication effectiveness between project participants were identified from literature review. A numerical assessment of these factors is developed and validated by conducting a questionnaire survey in Hong Kong, China. It was found that the top ranked significant factors affecting communication effectiveness between construction participants include: design and construction method complexity, schedule for communication and information distribution, time constraints for design and construction, the number of subcontracting companies, and the project manager’s capacity etc. Based on a factor analysis, these factors were grouped into six main categories, namely, social coordination and mechanism; technical coordination and construction management; information management regime; clear communication system; project characteristics and environment; and organisation structure. A conceptual model is proposed based on these four categories towards effective communication between project participants. The model provides a development framework for communication management strategies in construction projects.
IMPERATIVE OF ATTITUDE ON CHOICE OF MULTI-MODAL TRANSPORT IN DELHI
INDRASEN SINGH
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 levelof- 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.

PARTICIPATORY AND PARTNERSHIP MODELS FOR DEVELOPMENT AND MANAGEMENT OF URBAN INFRASTRUCTURE IN INDIA
RANNDIL SHER JATINDER SINGH
With the process of urbanization and globalization, infrastructure is recognized to be one of the vital components that contribute to the economic development and environmental sustainability. In India lately perceived the urgency of development and management of infrastructure. However, increasing that impediments in infrastructure are emerging as a major hindrance to economic growth. This requires two kinds of approaches i.e. involving public in development works and sharing development and management work with the private sector. The present paper highlights Participatory and Partnership models and their role in managing the urban infrastructure. This paper lays an emphasis in perception models already adopted in Indian context and the changes required for the positive role of these models in the urban management process

ENERGY MANAGEMENT FOR INFRASTRUCTURE
PRAMOD DESHPANDE
The infrastructure development is growing at the rate of 15% and above. The prime requirement for the growth is uninterrupted quality power. The major constraint is the secure electrical power supply. With new electricity generation regulations the infrastructure establishments are allowed to generate electrical power. The cost competitive power generation and utilization is a must for sustainability of the project and to maintain the environment. In order to optimize the energy requirement the most sustainable technology is that of Trigeneration. Trigeneration is an energy generation principle in which the electrical power - heating -cooling requirements are satisfied by a single source. This will maximize the efficiency of thermal and electrical systems and reduce environmental pollution.

APPLYING LEAN PRINCIPLES TO CONSTRUCTION PROJECTS

This paper presents some of the issues in the application of the principles of Lean production in a Construction context. While some aspects of production are common to a construction situation, Lean principles are not directly applicable to the construction context. While a Lean perspective can help in smooth workflow, other management practices, such as weekly planning, flexibility, decentralization and cooperation must be in place before we apply Lean principles for value addition and client satisfaction.
