Potential Application of BIM in Cost-Benefit Analysis of Demolition Waste Management

Bandar Lampung City is part of the major city of Lampung province. The problem that arises in Bandar Lampung City is solid waste management. The amount of solid waste in Bandar Lampung City reaches 1000 tons/day. One of the district of Bandar Lampung named Kedamaian district still uses the old method (collecting-transport-throw) in solid waste management, which causes the load of waste to accumulate in the landfill. The constraints encountered this time are the absence of sorting locations and limited land. Kedamaian district needs to develop waste treatment facilities, an approach based on Cost Benefit Analysis (CBA). The results show from the analysis that BCR in the scenario A <1 is 0.85 with NPV - Rp. 72.968.828. the activity in the existing conditions can still be carried out, but the waste reduction has not been maximized to the TPS (Container). Scenario B, NPV is Rp. 95.319.338 and BCR is 1.13, which value of BCR is >1. This indicates that a waste processing facility in the Kedamaian District is suitable to operate with TPS-3R. The results of scenario B are obtained by increasing the effectiveness of processing facilities to 100% by 2025. In 2025, with the implementation of the TPS-3R obtained, BCR is 1.20 with NPV is Rp. 218.447.621.

Waste Handling

Marine activities are environmentally sensitive, and this paper outlines waste management for a ship conversion company. Minimizing waste, reuse, recycling, and landfill are options in a hierarchy. Production process and waste handling were improved using industrial engineering and other techniques. A cost/benefit analysis showed ISO 140 as a potential source of competitive advantage as well as ensuring compliance with legislation.

PurposeConstruction and demolition waste (CDW) continuously causes environmental and social problems. These formidable challenges lead to sustainable issues and are an increasingly urgent issue worldwide. Prior studies have neglected to link the triple bottom line (TBL) to a reliable estimation or empirical model for estimating CDW production performance and lack empirical sensitivity analysis in profit maximization. This study proposes an attribute analysis to build a cost–benefit analysis (CBA) to obtain profit maximization.Design/methodology/approachThis study uses fuzzy set theory to develop a cost and benefit analysis (CBA) model to assess the sensitivity analysis in terms of its performance on addressing the environmental, economic and social aspects. The model is used to weigh the sum of benefits such as financial gain and total costs of actions taken to mitigate the negative impacts.FindingsBased on the sensitivity analysis conducted, the environmental, economic and social mean scales were significantly changed, i.e. increased, and profits increased drastically. The results provide an insight into environmental legislation compliance, environmental investment and environmental impact as the cause attributes for the CDW recycling profit increase. The results prove that sensitivity analysis is viable to infer that a sustainable production performance can achieve more revenue and profit through an adequate selection of attributes regarding the TBL aspects to address the firm's uncertainty problem in multiple criteria analysis.Originality/valueThis study builds a CBA model to maximize profits for recycled CDW material by linking of environmental, economic and societal aspects for recycled CDW assessments. It considers a sustainability structure with criteria based on TBL aspects to assess production performance to realize the Sustainable Development Goals and presents fuzzy set theory and sensitivity analysis to solve the uncertainty problem in the construction industry.
