This study is carried out with an objective to specifically identify the critical delay factors in the commissioning of metro rail projects in India. Methodology: A questionnaire survey was conducted to identify the major causes of delay from the opinion of clients, contractors and consultants. Calculation of Relative Importance Index (RII) for the shortlisted factors yielded the ranking. The ranking by various categories of respondents was analysed using Spearman’s rank coefficient. Main Findings:The study concluded in identification of 10 most critical delay-factors from a list of 49 shortlisted factors spread across 7 categories. The identified factors included: (1) Delay in land acquisition and site handover to contractor, (2) Shifting of utilities and contingency works, (3) Scope change, (4)Delay in payments, (5) Effects of unforeseen subsurface and ch...

The indicators, factors and attributes considered for evaluation are not consistent and are broadly based on knowledge base of the author. The purpose of this research is to identify building performance attributes based on user requirement. Design/methodology/approach With ISO 6241-1984(E) as a basis for universal acceptance, user requirements have been listed and based on these user requirements, related building performance attributes have been identified. End-user satisfaction is of primary importance to gauge performance of a facility. A quantified approach in evaluation of performance of a facility will enable a facility manager to assess the efficacy of the present policies pertaining to operation and maintenance of the facility. It will also provide valuable inputs to policy makers in initiating measures toward the goal of achieving desired user sati...

The average tensile strength of which vary from 620 to 1030 MPA as compared to the tensile strength of conventional Fe-500 bars which is in the range of 500 MPA. As in the case of normal Fe-500 bars, the main issue was of rusting hence to overcome this high chromium content is mixed for making the MMFX bars. The chloride content is also taken four times higher in case of MMFX bars than the normal carbon steel bars. An attempt has been made to check the savings in quantity of steel by providing reinforcement with higher capacity as compared to Fe-500. At the same time, a cost model is also tried to work out to check its overall feasibility as per Indian condition. The findings of this report will benefit the cost consultants as well as researchers who have keen interest to implement and encourage the us...

Design/methodology/approach User requirements in a building were listed from ISO 6241-1984 (E). Seven building performance attributes were identified through literature review and linked with the user requirements. Three more attributes not directly related to building performance but that could influence user satisfaction were also identified. The attributes were grouped into physical, environmental and external factors to suit the intervention strategies proposed to be implemented by maintenance agencies to enhance user satisfaction. The need for amplifying the attributes for better comprehension by occupants was felt; hence, characteristics of each of these attributes were listed based on literature survey and review. In total, 42 such sub attributes were identified to amplify ten ...

The Indian construction industry is one of the major stimulants of the economic and social growth of the nation. However, the sector is confronted by numerous issues, thereby reducing its efficacy and unhindered growth prospects. The purpose of this paper is to extract various industry impediments and suggest a prioritized listing of challenges faced by the industry using the Grand Challenges Approach (GCA). Design/methodology/approach – Motivated by the GCA this study uses the Delphi process for consensus building in the expert panel, comprising of 39 professionals from across various industry stakeholders. A qualitative round was first used to acquire views on the challenges. Consequently two quantitative Delphi rounds were conducted to extract Top-10 Challenges for the industry based on two aspects – priority and impact. A wider industry survey was also carried out, which served as an unscientific validation of the Delphi Study. Findings – Grand Challenges facing the Indian construction sector were identified. Addressing these challenges at the national level has the potential of transforming the industry to highly efficient, quality cantered and bullish industry capable of delivering successfully. Originality/value – The GCA, used extensively by the health sector internationally, is used for the Indian construction industry in a novel way to set an agenda for enhancing its operational efficiency.
