Criteria For Selection Of Design And Build Procurement Method
Alaeddin Ghadamsi and Nuhu Braimah
One of the causes of poor project performance (PP) is the use of inappropriate procurement method (PM). Whilst employing an appropriate method is considered to result in project success, limited research has so far been conducted to empirically explore this relationship. Although, a lot of studies have been done with a view to develop models/tools for aiding the selection process, there is much less research on the influence of procurement methods on project performance. This paper presents a conceptual framework to demonstrate the existence of this influence. The framework is developed based on an extensive review of literature. The review was carried out to determine the main criteria for selecting Design and Build procurement method (DB) and project performance measurements. Thirteen (13) DB procurement selection criteria commonly cited in the literature were identified. A review of how each of these criteria suits the use of DB method was also carried out. The latter part of review was to facilitate ranking of each of the criteria on a rating scale for purposes of predicting the actual level of influence a particular procurement method exerts on performance of a project. Besides offering a deeper understanding of PM relationships with PP, the proposed conceptual framework forms a basis for the development of the quantitative model at subsequent stages of the on-going study.

Achieving Academic Excellence Through Project Risk And Complexity Management
Debasis Sarkar and H.B. Raghavendra
Project risk management is an integral facet of project management. Complex infrastructure projects are subject to risks and uncertainties through all stages of the project i.e. from feasibility, development to execution and operation. These risks and uncertainties would reduce the probability of successful completion of the project within stipulated time and cost frame. Academic institutions face the present day challenges of recession, inflation and constricted job market. Achieving academic excellence and becoming a “world class institution” is a real challenge for the Indian universities. Further, in an academic institution with a focus on energy and infrastructure, the courses and programmes offered under the domain of “energy” may not synergize with the courses floated under the domain of “general engineering” or “liberal studies”. Due to the stand alone nature of these domains, the institute faces various risks and challenges in achieving academic excellence in all programmes and courses floated under “non-energy” domains. This paper is an attempt to identify the major risks, uncertainties and complexities of an educational organization focussed on “energy infrastructure” based on different programmes floated by its constituent schools. An analytical approach for analysis of the risks is carried out, based on which, a risk and complexity management model would be proposed. The proposed model would be a combination of project risk management and programme risk management. As risk is a function of likelihood and impact, the likelihood or probability of occurrence values of the identified risks were obtained through a questionnaire survey and the respondents were faculty members and students of the academic organization under study. Generally, the mean of the responses is considered for the study and the tool applied for analysis is Expected Value Method (EVM) for Project Risk Analysis (PRA). Risk severities obtained from the analysis enabled to classify the risks into “low”, “medium”, “high”, “very high” and “critical” zones. A risk map was developed which was linked to the probable solutions of reducing the severities of the identified risks. The risk response planning and mitigation measures acted as a risk mitigation tool. The proposed methodology would strengthen the link between the strategic planning and implementation, so that the project outcomes are predictable, reliable and consistent and can correlate with organizational success. It would also identify the best practices which support the implementation of academic organizational strategy through successful programmes. Methodologies to generate more synergy between the standalone programmes of different constituent schools would also be suggested.
Liquidity And Profitability Analysis In Selected Oil And Gas Refineries In India
P. Hanumantha Rao
Indian economy has remained stable and strong during last one decade or so when most of the emerging economies in the world have witnessed a downward trend. One of the main reasons for this could be the industrial sector of India which has played a very significant role in realizing the higher economic growth in the country. The oil and gas refinery sector, being one of the eight core industries in India, plays a major role in influencing decision making for all the other important segments of the economy. In this context, it becomes very relevant to look into the fundamentals of some selected oil and gas refineries in India over a period of last five years. This paper attempts to study the liquidity and profitability position of four such companies, namely Indian Oil Corporation, Oil and Natural Gas Corporation, Hindustan Petroleum Corporation and Bharat Petroleum Corporation Ltd for last five years from 2010-11 to 2014-15. The key variables considered for this study include current ratio, quick ratio, return on equity, return on capital employed and return on assets.

Bus Rapid Transit System For Indore City
Kundan Meshram and Dilip Singh Yadav
Bus Rapid Transit System (BRTS) is a bus based good quality, high capacity rapid transit system that delivers fast, comfortable and cost effective urban mobility. In a BRTS, vehicles travel in exclusive lanes, thus avoiding congestion, accident, air and noise pollution. There is a provision of segregated right-of-way infrastructure, rapid and frequent bus operations, easy boarding and alighting facilities for the passengers and excellence in marketing and customer service. BRTS is a safe and cost effective transit option for urban cities. The present work describes a case study of BRTS for Indore city. BRTS started from Niranjanpur to Rajeev Gandhi Square located on Agra-Bombay road (A. B. road) in Indore. The length of the corridor is 11.57 km with 22 bus stops and 4 BRTS Interchange Stations are identified along the corridor. The corridor is divided into three stretches viz. stretch 1 from Niranjanpur to LIG Square, Stretch 2 from LIG to Holkar College and Stretch 3 from Holkar to Rajiv Gandhi square. The study also calculate number of buses required for present traffic load and with increase traffic from 10% to 40% on feeder roads.

Use Of Crushed Sand As An Alternative Construction Material To River Sand - A Review
A. L. Agarwal and B. L. Rajput
The demand of the natural river sand has increased manifold for the production of concrete which is an extremely versatile construction material used in all types of construction. The river sand is a product of natural weathering of rocks during the flow of a river over a period of many years and is mined from the river beds. River sand is becoming a scarce natural resource.The use of river sand is being constrained by various environmental laws, zoning regulations, increased cost due to nonavailability and environmental concern. This review paper summarizes various studies undertaken on use of crushed sand as an alternative construction material to river sand as a partial or the full replacement. It was observed from the previous experimental studies that the addition of crushed sand as replacement to natural river sand may improve strength and durability of the concrete.
