Workplace fatalities and injuries have significantly reduced since 1970 after implementation of OSHA (Occupational Safety and Health Administration) regulations. However, ergonomic injuries caused by ergonomic risk factors such as awkward or sustained posture, forceful exertion or stain, contract pressure, exposure to vibration, extreme heat or cold environment have major impact on the productivity and safety on the highway construction sites. The paper focuses on identifying the existing safety practices that aid to prevent ergonomic injuries at the highway construction sites. A comprehensive review of literature reveals that majority of work place injuries and fatality victims are from private employment whereas a very few injuries coming from the state or local government employees from contractors. The primary data was collected using questionnaire survey, interview and observations and the spreadsheet was used to analyse the collected data about the causes of workplace injuries and possible measures. The survey results reveal that the most of the injuries such as musculoskeletal disorders, strain and accidents transpired due to the collision with equipment and vehicle!s related incidents. Dump truck, tippers, motor graders and cars cause the frequently reported workplace injuries. The paper concludes that use of Personal Protective Equipment (PPE), compliance to safety regulations, improving traffic control system and changing the culture of employers and employees are possible safety practices need to be adopted to mitigate the ergonomic workplace injuries in the highway construction projects particularly in the developing and least developed countries.","PeriodicalId":306432,"journal":{"name":"Journal of Advanced College of Engineering and Management","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124513357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper outlines the common observed damage patterns of different types of buildings in Kathmandu valley induced by the earthquake and their constructional deficiencies..We visited Department Of Urban Development and Building Construction (DUDBC) of Nepal Government, and Nepal Society for Earthquake Technology (NSET) and got various information regarding structural damages caused by Gorkha earthquake. After acquiring knowledge on this topic through internet and from NSET and DUDBC, the structural failure analysis of buildings affected during the earthquake in Kathmandu Valley was done by photo observation. Both unreinforced masonry buildings and reinforced masonry structures suffered low to heavy destruction. The construction and structural deficiencies were identified to be the major cause of failure, however local soil amplification, foundation problems, liquefaction associated damages and local settlement related damages were also significantly observed during this earthquake and reported in the paper. The Gorkha earthquake sequences delivered unprecedented opportunity to augment the understanding on seismic performance of the buildings. This paper is also motivated to point out the faintness in the past to current constructional practice of buildings, provide preventive measure and convey awareness to stake holders for future safer building construction practice.","PeriodicalId":306432,"journal":{"name":"Journal of Advanced College of Engineering and Management","volume":"428 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134069107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the purpose of study Reshunga municipality was taken, situated in Gulmi district of Nepal occupying an area of 82.74 sq.km. For collection of data, 368 houses were surveyed and the locals were interviewed on their annual consumption. The total energy consumption was 214.8 TJ where 78.25% was supplied by wood. LPG shared 16.14% of demand. Cooking (58%) and water boiling (26%) were the most demanding task. Most of the houses were equipped with ICS, with share 55% of energy demand in cooking. Four different scenario were studied viz. BAU, DSM, BSP and SDG. In, BAU scenario, the energy consumption will reach 245.3 TJ. In DSM scenario and BSP scenario the final energy demand will reduce to 230.7 TJ and 216.2 TJ. In SDG scenario, energy demand is reduced by 23.14%. The share of LPG increases to 22.36 % and electricity demand becomes more than doubles from reaching 10.64% in SDG. From year 2017-2030, there will be total accumulative increase of electricity requirement by 47.4 TJ, whereas total cumulative decrease of 433.5 TJ equivalents can be resulted in consumption of wood in SDG scenario. Cost-Benefit analysis study revealed that DSM will require an investment of 43.03K US$ for demand technologies and will reduce emission by 8.69 tCO2e. DSM will be cheapest in terms of cost per GHG reduction. SDG will cost 645.46K US$ and results in reduction of GHG by 47.79K tCO2e.","PeriodicalId":306432,"journal":{"name":"Journal of Advanced College of Engineering and Management","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125312290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inherent variability of parameters make the problem probabilistic rather than a deterministic one. This research deals with evaluation of stability of slopes with the calculation of the factor of safety of Dasdhunga soil slope along Narayangarh- Mugling road section under different rainfall conditions through the use of coupled finite element and limit equilibrium method in GeoStudio and the determination of probability of failure by sliding, modeled as infinite slopes by using Monte Carlo simulation in R-Studio. Mean, standard deviation, minimum and maximum values of the parameters like- friction angle, cohesion and unit weight were computed from eight samples of the slope. The pore water pressure developed and its corresponding statistical data for different rainfall conditions were computed from FEM based SEEP/W simulation. The above parameters are assumed to follow truncated normal probability distribution function and the geometric parameters like height and slope angle are regarded as constant parameters. It was observed that the safety factors for theslopeis low in high intensity-low duration rainfalls and the probability of failure is high. The tendency to fail increases as the return period of rainfall increases and viceversa. Sensitivity analysis performed in both deterministic and probabilistic methods showed that friction angle is the most sensitive.","PeriodicalId":306432,"journal":{"name":"Journal of Advanced College of Engineering and Management","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116689683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
