BIM Based Inventory Management in Construction of Residential Highrise Building in India

Abstract

According to a study, construction materials account for more than 65 percent of a project's entire cost. Material Planning efficiency is critical to completing a project on scheduled time and on budget. This research paper focuses primarily on inventory control and materials planning using BIM process as this are the important pillars of material management. The S-curve analysis is used to determine how much the estimated materials cost differs from the market materials cost. Engineers and contractors are interviewed to determine the main reasons for this. Inventory management techniques such as ABC classification and economic order quantity (EOQ) analysis are performed. In most cases, S-curve analysis shows that actual material costs are greater than estimated material costs. BIM-based ABC and EOQ analyses are used to continuously maintain sufficient inventory, protect inventory materials from damage, reduce inventory costs, solve inventory problems, and maintain optimal inventory levels. A sensitivity check is applied to the results of the EOQ analysis. “The use of ABC classification and EOQ analysis can help to alleviate the stock-out of A class and B class materials that occur on building sites. Following the implementation of these easy inventory control strategies, the total inventory expenditure is reduced”.
