To study the inefficiencies in contract management practice in SNRTP rural road projects, the checklist was prepared and data regarding the contract management were obtained with the project stakeholders. The data were collected using questionnaires, analysed using SPSS software, MS Excel and presented using the graph, table, and charts.The findings of the study showed that there are significant inefficiencies in contract management practice in the SNRTP project. It has been found that the majority of the respondents i.e. 79 percent of the experts interviewed opined that there are inefficiencies in the contract management practices in the rural road under SNRTP sub-projects, and only 21 percent think that the process is efficient from questionnaire survey. This has been statistically verified through descriptive statistics. The reason behind the inefficiencies in Contract Management Practice is mainly due to a lack of qualifications, knowledge, skills & experience of the contract management team, lack of cooperation & proper communication between project team member, lack of monitoring & evaluation in time, lack of timely meetings, slow decisions making, and improper planning & poor site management during the construction work. To overcome those inefficiencies some suggestions have been recommended as appointing the team member with proper qualifications, knowledge, skills & experience in the contract management. Proper communication & cooperation between team member, frequent inspection, monitoring and evaluation, completion of work within intended completion time, proper record keeping & timely issue management, and timely decision making from all stakeholders as required in construction work during the project implementation phase.","PeriodicalId":402805,"journal":{"name":"Journal of Advanced Research in Civil and Environmental Engineering","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125241035","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 Bayer process is most commonly adopted to extract alumina from the ore bauxite. Globally, nearly 3 billion tons of Aluminium Refinery Residue (ARR) is stored. The storage of untreated Aluminium refinery residue consumes more open land for storage. The present article discusses the material properties like grain size analysis, consistency limits, specific gravity, maximum dry density, optimum moisture content, unconfined compression strength test, and durability properties of stabilized Aluminium refineries residue with ground granulated blast furnace slag (25%), a combination of alkaline solution at 5% Na2O, Silica modulus and its probable application as road construction material. Results have shown an increase in UCS (average 381%) values of the stabilized ARR at 0,7 and 28 days of curing compared with same day cured sample and Problems associated with the earthen road construction material is the reduced strength and weathering due to exposure to harmful climatic conditions. So the prominence has been given to the durability of the stabilized Aluminium Refinery Residue (ARR) by considering the effect of Wetting and Drying (W and D) cycles on its weight loss which is within the limits as specified by codes.","PeriodicalId":402805,"journal":{"name":"Journal of Advanced Research in Civil and Environmental Engineering","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131517894","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 study aim was to assess key performance indicators for health building construction, its ranking, the most important affecting factor for each KPI, and how to improving KPIs in a health building construction in Nepal. The data were collected from project stakeholders through a questionnaire survey. The project stakeholders were the contractors and health building section personnel of DUDBC. Data were summarized, analyzed, and presented in tables using Microsoft Excel. The study found that the stakeholders working in health building construction projects thought quality factor as the most important KPI with the first rank. The cost factor and time factor are correspondingly second and third-ranked, whereas, client satisfaction is the least important KPI. The study also showed the Relative Importance Index (RII) for the various factors affecting each KPI in the health building construction. For KPI-cost most important affecting factor is price escalation. For KPI-time it is the approved project schedule. The possible ways to improve the KPIs in health building construction are listed as conducting regular management meeting, implementing the provisions of the contract agreement, establishment of the proper communication system, timely monitoring of the progress, establishment of quality assurance and control system, adaptation of the cost and schedule control system, ensure the proper health and safety provisions to the workers, an early warning system for changes, regular updates of the work plan and program, regular training on project management, proper site management, proper management of manpower involved in the construction and better inventory management of contractors.","PeriodicalId":402805,"journal":{"name":"Journal of Advanced Research in Civil and Environmental Engineering","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134018151","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}

In response to this pandemic, Nepal Government announced a country-wide lockdown from 24th March 2020 and ended on 21st July 2020. Coronavirus pandemic is an unprecedented event affecting almost every aspect of the construction sector in Nepal. Hence, this study was carried out to assess the impact of COVID-19 lockdown on Nepal’s construction sector based on selected construction projects. For this purpose, a case study of five ongoing construction projects was taken into account and questionnaires were distributed to responsible officials (client, consultant and contractor) of those projects. This study intended to find out the impact of COVID-19 lockdown on supply-demand trend analysis, cost and time of construction projects. Besides, this study also intends to find the contractual issues and claims associated with COVID-19 lockdown. The study reveals that COVID-19 caused serious disruption to the supply chain. Subsequently, project cost and time increases due to uncertainty regarding the availability of subcontractors/ suppliers/labour. The impact of COVID-19 lockdown however varies with the nature, scale and size of the project. Besides, the study also implies that contractual disputes are likely to increase due to lockdown. Each contract and its conditions have to be carefully analyzed to determine a party’s specific entitlement. There is uncertainty as to when the situation becomes normal and construction work can be carried out with optimum efficiency.","PeriodicalId":402805,"journal":{"name":"Journal of Advanced Research in Civil and Environmental Engineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115877327","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 overall objective of this research is to analyze the risk management practice in an urban road construction project with a case of Shiddharthanagar Municipality, Rupandehi, Nepal from contractor’s and client’s perspective. This research is based on a scheduled questionnaire survey to collect the primary data using convenient sampling of the partially or fully completed project. Contractors are quite aware of risk management and the percentage of awareness is even higher among the clients. The feedback from a similar project was used as the main method to identify the potential risk of the project from both contractor’s and client’s perspective. Direct judgment method is used maximum to the analyzed risk of the project from the contractor’s perspective as well as scenario analysis from the client’s perspective. Monitor the risk and prepare a contingency plan is used mostly for risk response of the project from both contractor’s and client’s perspective. An alternative plan, subjective judgment, close supervision, increment of resources and change in construction methods were applied as a preventive and remedial strategy. Risk should be managed by the one who is capable of managing the particular risk by managing contractual obligation with proper contract administration practices for ensuring the project objectives. There should be a risk register at the site and a frequent meeting should be conducted to identify the risks. These identified risks should be documented properly to ensure expertise for future projects.","PeriodicalId":402805,"journal":{"name":"Journal of Advanced Research in Civil and Environmental Engineering","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133058789","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}

Many nations are observing an expeditious growth in the field of construction necessitating the utilization of natural reserves for the expansion of infrastructure. This expansion is giving a warning to available reserves of nature. The natural ingredients, fine aggregates and coarse aggregate constitute more than 70% volume of the concrete. The availability of these resources is decreasing at a very high pace. In fact due to the severe problem with the availability of natural sand, the construction industry is faced with the pressing need to consider available options to lessen the reliance on natural aggregates. Copper slag being a waste material, can be used as an option for fine aggregates. The substitution of fine aggregate from nature with waste materials from industries such as copper slag offers economic and technical dominance, which are of pronounced significance in the present scenario. This study is, based on the critical review of the development of High Performance Concrete (HPC) by replacing fine aggregate with copper slag by observing various other researches and reviews. The key intent of this paper is to closely look at the copper slag utility as an unconventional material to be used as a substitute of fine aggregate and its effect on mechanical and durability parameters of HPC.","PeriodicalId":402805,"journal":{"name":"Journal of Advanced Research in Civil and Environmental Engineering","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129791839","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}
