Building information (BIM) is becoming a better-known collaboration process in our construction industry. BIM is a systematic process that amalgamates all the other geometric computer-generated models, or data that creates simulations that can be used for the project manager, owners, facility manager or other parties to look after the project and deliver the project more efficiently. The implementation of BIM in India is still at a nascent stage due to a lack of knowledge of the advantages of BIM. Moreover, there have been only a few case studies conducted in India about BIM; therefore, the principal agenda of this study is to enlighten the readers about the benefits accrued if BIM is applied, in the residential project, before the construction. Hence, the authors had taken a residential project located in Gujarat, India, for a case study. The 3D and 4D models of the project were generated; 8 errors were identified that could have been detected before construction if BIM had been applied. The cost needed to make a BIM model was ₹ 171,050. Whereas, the amount that could have been saved if BIM was implemented beforehand was discovered as ₹ 246,773. Consequently, the benefits to cost ratio for two weeks in delay was determined as 1.44. It can be as the benefit of BIM for construction.

Recent technological improvements have made substantial changes in construction industry. In specific, some technical applications, such as Building Information Modeling (BIM), open up many possibilities. Some studies have articulated the use of BIM and its advantages in construction, but most of them are theoretical, not practical. This study is to provide an insight to obstacles in BIM research. By investigating a real project that could utilize BIM in planning and construction phases, the authors try to investigate a possible outline of advantages in BIM implementation. The study area was set to a railway construction site in South Korea. The site covers multiple railway tracks, stations, telecommunication facilities, infrastructure facilities, railway structures, and so on. In the site, the authors have identified 12 errors in 7 projects that could be prevented if BIM was utilized before the construction. The total upfront costs required to provide a BIM for the seven projects was $116,348. On the other hand, the total costs required to fix the errors in the seven projects was $166,486. This can be regarded as the benefit of using BIM, because if BIM was implemented then the associated errors could easily be replaced. Therefore, the benefit–cost ratio can be estimated as 1.32 for one-month delay and 1.36 for a three-month delay.

The economic assessment of transportation projects is evolving from a reliance on user benefits (travel time, cost, or safety) to encompass a wider spectrum of potential benefits, fostered by advances in economics and recognition that different project modes deliver different portfolios of benefits. Sponsors develop projects to address specific problems in their communities. This progression in how investments are evaluated opens the door for projects whose outcomes span a variety of benefit categories rather than concentrating on traditional user benefits and permits an improved intermodal comparison of candidate investments. Transit and intercity rail projects are particular beneficiaries of the broader project assessment approach. This paper presents a case study of how a comprehensive approach to project assessment was applied to the Northern Lights Express project that would reintroduce passenger rail service between the cities of Minneapolis and Duluth, Minnesota, the state's largest economies. Owned and operated by BNSF Railway, Amtrak's service in the corridor ended in 1985. Six stations are planned: Target Field in Minneapolis; stations in Coon Rapids, Cambridge, and Hinckley, Minnesota; a station in Superior, Wisconsin; and Union Depot in Duluth. The goal for the analysis was threefold: ( a) to confirm that the investment would yield a positive return; ( b) to communicate with partners, stakeholders, and the public about the project's expected outcomes; and ( c) to contribute to the selection of an alternative. The benefit–cost ratio was estimated for eight alternatives that varied by physical alignment and service plan.

The present study for performance evaluation newly developed varieties of CIM –Kranti and other varieties of menthol mint cultivation has been carried out at farmers’ field of central Uttar Pradesh. Mints are commonly used as the source of fragrance, flavor and pharmaceuticals industry. During the study period 2017-18, 100 farmers cultivating CIM-Kranti and other varieties have been selected from the region of central Uttar Pradesh. The primary data were collected from the selected farmer’s field on profitability comparison between CIM-Kranti and other varieties under cultivation. The highest area and production has been observed during 2012 and 2013. Simple statistical tools and techniques have been used for data analysis of the cost of cultivation and profitability. It has been observed during the study that CIM-Kranti gives higher returns (.98491/- ha/year) over other varieties (.70977/-ha/year). However, the input cost of CIM-Kranti is higher than other varieties of the crop but the net return of CIM-Kranti was more profitable than other varieties. The benefit cost ratio has been observed 1.45 and 1.74 of other varieties and CIM-Kranti respectively. The new variety “CIM-Kranti” of menthol mint is cold and frost tolerant and has the potential to produce 10-15% more oil i.e. 145-160 kg/ha in summer season as compared to all other popular commercial cultivars of menthol mint.It is suggested from the study that maximum profit is generated through CIM-Kranti cultivation followed by other varieties crop.

Ghana has had a long-standing problem of illegal gold mining that has led to the destruction of the environment. The government of Ghana is taking steps to not only curb illegal mining but also to restore destroyed lands that resulted from illegal mining. The government intends to spend financially in the area of ecological restoration to returned disturbed lands to their natural states possible, but the question remains whether restoring those disturbed lands will be beneficial to the country. The study was undertaken in Bekwai Municipal Area in the Ashanti region of Ghana where most locals are farmers. The research studies whether the benefits of ecological restoration outweigh the cost of ecological restoration? The research deployed a quantitative data collection. The data collected was analyzed using benefit-Cost ratio. The result shows that the benefit of ecological restoration outweighs the cost incurred as dependent on the land use as a carbon sequestration project. In conclusion, investment in ecological restoration is a step in the right direction for a country endowed with gold resources. This will spur growth and at the same time improve and protect the country’s natural resources and environment.

Study Case

Background: The Building Information Modelling (BIM) methodology has been acquiring, worldwide, a growing acceptance in all sectors of the Construction industry, and the study intends to contribute to its implementation within the structural design. The fundamental concept of BIM is based on the generation of a centralized virtual model with all information concerning different specialties. This is supported in efficient interoperability, but within the structural design, this aspect is difficult to achieve completely, as currently, the interoperability of this system is still inefficient. Introduction: This study intends to analyze the degree of interoperability verified in the development of all the processes (modelling, transposition, structural analyses and reinforcement detailing) involved in a structural design using BIM tools. Methods: A structural project concerning a study case was performed in order to identify benefits and limitations, based on the consistency analysis of the transposed data between systems, Revit and Robot, in all steps required in a BIM process. This text describes the stages of modelling, checking the suitability of the analytical model, its transference to the analysis tool in order to proceed with the structural calculations and detailing drawings and, finally, the transfer of drawings to the main BIM model. Results: The limitations verified in the last stage were partially surpassed with complementary work enabling the automatic transfer of drawings and quantities of materials. In addition, the study explores new capacities of BIM, namely, the extraction of information allowing the presentation of specific drawings and maps of the geometry of the reinforcement rods. Conclusion: This study identifies a working strategy that leads to an appropriate use of BIM software contributing to the optimization of labor in a structural office.

Transportation research projects are a vital element for transportation agencies to accumulate new technology and knowledge to improve the efficiency and safety of transportation infrastructure. The purpose of this paper is to develop benefit cost analysis (BCA) tools to assist transportation agencies in evaluating transportation research projects. The BCA tools provide analysis methods for estimating the benefits for changes in the level of service (LOS) of a roadway, reductions in the vehicle travel time, changes in vehicle operating costs and reductions in the number of crashes. Three case studies were investigated to illustrate the usage of the BCA tools. The first case study evaluated the effectiveness of variable speed limit systems implemented along I-80 in southern Wyoming. The BCA tools estimated a benefit cost ratio of 6.64 indicating that the implementation of the project was economically justifiable. The second case study was a recent study investigating and developing mitigation strategies for the effects of truck traffic along the I-80 in southern Wyoming resulting in a benefit cost ratio of a 9.23 indicating that the project had the potential to be economically viable upon implementation. The final case study evaluated the effect of wildlife overpass and underpass crossings on the migrations of pronghorn and mule deer. The benefit cost ratio for the research project was 0.42 indicating that the project was not economically beneficial after the first year of implementation. The case studies indicated that the BCA tools are a beneficial tool for quantifying the economic benefits of a transportation research project.

A survey study was conducted to study the benefit-cost analysis of apiculture enterprise in Jutpani VDC, Chitwan district. Data were collected by interviewing randomly selected 18 beekeepers for sample survey. Benefit : Cost (BC) ratio of apiculture was computed by including and excluding the revenue obtained from colony selling. Only 61.11% of beekeepers sold bee colonies for earning income. The study revealed that BC ratios of apiculture were 2.41 and 1.58 in the case of inclusion and exclusion of the income received from the colony selling, respectively. It showed that apiculture industry was running in profit in both cases. In the former case, the BC ratio ranged from 0.97 to 6.22 and about 88.88% beekeepers were in profit. The BC ratio in the later case ranged from 0.43 to 3.41 and about 77.77% beekeepers were in profit. The number of colonies ranged from 2 to 54 with an average of 21.33 colonies per bee farm. In the former case, average annual income was Rs. 70758.33 (US$ 969.29 approximately) per farm and Rs. 49588.31 (US$ 679.29 approximately) in the later case. Likewise, the average income per colony per annum was Rs. 3317.31 (US$ 45.44) and Rs. 1777.65 (US$ 24.35 approximately) in the former and later case, respectively.

This study was conducted in 2020 to determine the profitability and productivity of organic turmeric production in the Surkhet district of Mid-western Nepal. Face-to-face interviews were conducted with 60 farmers and two focus group discussions were held in four different communities. Turmeric is commonly utilized among Nepalese households in the preparation of curries and is considered one of Nepal’s top five major spice crops. Despite being one of the top five-spice crops, Nepal’s dependency on imported turmeric has been growing every year to meet domestic demand due to the gradual decline in domestic production. The simple descriptive and statistical tools including the Cobb-Douglas production function and benefit-cost analysis were used to analyze the result. The benefit-cost ratio was found to be 1.20, indicating that organic turmeric production was a low profitability sub-sector with a productivity of only 9.06 metric tons per hectare. The Cobb- Douglas production function showed that the cost on seed had a non-significant effect on gross returns and other costs like human labour cost, organic manure cost, ploughing cost, and other costs (agriculture equipment, thread, sack/doko, and rhizome treatment) were found statistically significant. Return to scale was calculated using the Cobb- Douglas production function and it was found to be 0.363, indicating that a 10% increase in the cost of production increases the rate of return by 3.63%, which is a diminishing rate of return. As a result, replacing human labour with agricultural machinery, lowering seed costs, and ensuring appropriate market prices are required to boost the productivity and profitability of organic turmeric production in the research area.
