    Demand shortfall in infrastructure construction projects: case of rail projects in India
    (2017) Kumar, MY; Kumar, PV
    This paper presents the case of shortfalls from the forecasted demand in feasibility studies of infrastructure construction projects (ICP). The demand forecast is generally required during the project formulation stage. An accurate or ‘close to reality’ demand forecast is significant for the success of any ICP. The paper highlights the role of the utilization of a project on the financial and economic sustainability of ICP. It also identifies the components of a project affected by the change or shortfall in demand. An evaluation of a feasibility study is done keeping the focus on demand and its consequences on expected financial and economic benefits of the project. A metro rail project is selected as a case study for the comparison of forecasted demand with the actual demand after commissioning of the project. The outcome of the exercise revealed substantial variations in demand. The case is then analysed for the extent of variation in the forecasted and actual benefit streams related to the financial and economic performance of the case example. The methodology is applied to a set of similar projects for analysing the universality of the phenomenon. The results prove that ICPs often face a demand shortfall and this has far reaching implications in terms of cost of underutilization. Finally the paper comments on the critical role of demand forecasting in meeting the objectives and success of ICP.

    Investigating the impact of non-load bearing (nlb) walls on the built-up area and dead load in multi-storeyed residential buildings
    (2019) Abhijit, R; Kumar, PV; Samarawickrama, S
    The Indian housing sector is transforming rapidly. Over the last decade, change is noticeable because we transformed from multifamily independent houses to multi-storeyed dwelling units. There are several reasons behind this transformation, like change in culture, work styles, lifestyles, etc. but the most significant is space availability. A typical multi-storey house has a floor plate, which has multiple Dwelling Units (DU’s). The same configuration of the floor plate is repeated over the floors above it. The structure type is commonly an R.C.C framed in which the walls are Non-Load Bearing functioning merely as partitioning member. The thickness of these Non-Load Bearing partition walls contributes significantly in reduction of Net-Useable area of dwelling unit. It also contributes in the overall dead load of the structure. Thus, this research aims to analyze the configuration of dwelling units (DU’s) of different sizes ranging from 1 Bhk to 4 Bhk spread across different regions in India on the above two parameters. The architectural layout of these DUs has been analyzed in relation to useable and non-useable areas, whose proportion is usually referred to as "Loading”. The study revealed that the a) Internal Layout Design, and b) Partitioning Walls are the two main factors responsible for “Loading”. The outcome of this study will provide a baseline to support efficient space planning and decision-making for the designers and developers thus helps them to manage residential spaces more efficiently
