This is with a view to ascertaining the possibility of using the referenced banana leaf ash (BLA) content to stabilise the soils, for road construction purpose. To achieve the aim of this study, two soil samples were collected from two identified borrow pits (one sample from each borrow pit – referred to as Sample A and Sample B respectively) in Ile-Ife, southwestern Nigeria. Using standard procedure, preliminary and geotechnical tests were conducted on the soil samples in their natural states. BLA was then prepared and introduced to the soils at varying proportions of 2 %, 4 % and 6 % by weight of dry soil. The Atterberg limits and California bearing ratio (CBR) were subsequently determined for the treated soils. For the natural soils, results showed that: the plasticity index values for Sample A and Sample B were 22.91 % and 26.60 % respectively; the specific gravity values were 2.71 and 2.75 respectively; the optimum moisture content (OMC) and maximum dry density (MDD) for Sample A were 26.50 % and 1.325 Mg/m3 respectively, while for Sample B the values were 19.80 % and 1.643 Mg/m3 respectively; and the CBR values were 6.85 % and 11.36 %, respectively. With the addition of BLA: plasticity index generally reduced with the lowest values (4.89 % and 6.24 % for sample A and Sample B respectively) at 6 % BLA content; the CBR steadily increased until optimum values (10.23 % and 22.73 % for Sample A and Sample B respectively) were obtained at 4 % BLA content. The study concluded that: BLA could be used to improve the properties of lateritic soils for road construction purpose; and the particle size of BLA used does not diminish the quality of BLA as a soil-stabilising agent.","PeriodicalId":360552,"journal":{"name":"International Journal of Civil Engineering, Construction and Estate Management","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134234104","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}

Taxation of instruments is the process of imposing a tax on instruments such as mortgages, deeds, and other documents. Taxation is typically done by the local or state government to generate revenue. It is important to note that taxation may vary by state or jurisdiction. This paper however examined land-based taxation practice for instrument registration on Anambra State. Findings indicated among others that that the land-based taxes levied for instrument registration were direct tax, capital gains tax and stamp duty. The study found out that the law provided that the basis of assessment on capital gains tax, is 10% of chargeable gains and the methods of assessment OGT Discount Method, Indexation Method and Other Method (where OGT Discount Method Indexation Method are not suitable). It noted that land and landed property is an undisputable as well as important base for mobilizing revenue to meeting the needs of the locals which Anambra State Government keyed into for revenue generation.","PeriodicalId":360552,"journal":{"name":"International Journal of Civil Engineering, Construction and Estate Management","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133830597","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}

To achieve the aim of this study, soil samples were collected from selected 20 construction sites in the study area. Using standard procedures, preliminary and geotechnical tests such as natural moisture content, particle size analysis, specific gravity, Atterberg limits, compaction and triaxial tests were conducted on the soil samples. Subsequently, Terzaghi’s bearing capacity equations were employed, alongside already determined shear strength parameters, to estimate the bearing capacity of different footing geometry (circular, square and strip footing). Results showed that majority of the soil samples are well-graded and could also be classified as A-2-4. Results of triaxial tests also showed that the soils are all c-ϕ soils. For each of the soil samples, square footing had the highest bearing capacity while strip footing had the lowest. It was also concluded that the tested soils are all excellent to good foundation materials.","PeriodicalId":360552,"journal":{"name":"International Journal of Civil Engineering, Construction and Estate Management","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124817263","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}

However, the construction of the MOX Fuel Fabrication Facility has proven to be a more complex endeavor than many of the project planners had initially anticipated. To date, the project has yet to be completed, and in February 2019, the National Nuclear Security Administration issued a contract termination notice for the project. Currently, the United States Department of Energy is looking into what it refers to as the dilute and dispose approach to dealing with the nation’s aging stockpile of weapons-grade nuclear material. The present research aims to explore solutions for overcoming the failures that occurred during the planning and construction phases of the MOX Fuel Fabrication Facility. The paper proposes that the adoption of Integrated Project Delivery (IPD) and Public-Private Partnership (PPP) might provide solutions for such cases. This study is supported by a review of relevant literature examining the effects of implementing both IPD and PPP.

Social media is Internet-based software and interfaces that allow individuals to interact with one another, exchange details about their lives such as biographical data, professional information, personal photos and up-to the minute thoughts. Just as the conventional traditional media like newspaper, radio and television are used to communicate development issues, social media has also become a tool for development communication. This study investigated role of social media in enhancing the development of road infrastructure in South East Nigeria. The study employed critical literature review method. It was anchored on Development Media Theory. Two research questions guided the investigation. Findings show that social media reportage makes the government aware of the state of roads in South East Nigeria, this makes the government to intervene in the repair of bad roads in South East Nigeria. The paper recommends that users of social media should intensify reports on the state of bad roads in South East Nigeria in order to draw more government attention; social media users should balance their reports of bad roads and good roads to encourage the government to do more.","PeriodicalId":360552,"journal":{"name":"International Journal of Civil Engineering, Construction and Estate Management","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114580858","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}

Modal choice behaviour especially in developing cities with less developed transportation infrastructure have been impacted in an unprecedented manner. This paper aims to assess the impacts of covid-19 on modal choice behaviour of commuters in metropolitan Lagos. The comparison was made with the modal choice behaviour of commuters in the metropolis before the pandemic period. To harness the data for impacts during the pandemic, a total of 1,256 commuters’ opinion were sample through structured questionnaires administered mainly by electronic/internet media. It was observed that while the frequencies of modal choices such as private vehicle and walking increased during the pandemic, the frequencies of other modes such as taxi, Keke (tricycles), Danfo (commercial busses0 and BRT (LAGBUS) decreased. Also, the commuting cost of Keke, Danfo and BRT increased significantly. Travel time for BRT and walking mode also increased. In addition to these, about 43% of respondents are of the opinion that shortage/lack of transportation was the most severe impact of the pandemic. This is caused by the limited choices in transportation that exist in the State. It is therefore recommended that there should be a well-balanced transportation system with sustainable alternatives in Lagos metropolis, made available for commuters and at an affordable cost.","PeriodicalId":360552,"journal":{"name":"International Journal of Civil Engineering, Construction and Estate Management","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114782103","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 research adopted the Urbanized Indigenous Peoples Settlements. These constitutes 14% of the 773 indigenous Settlements that were inexistence at the promulgation of Abuja as the Nigerian New Federal Capital Territory in 1976. In the second stage of data collection,10% of the houses was selected by simple random sampling technique to give a total of 1349 Households. The results of the study revealed that adult constituted lowest proportion (3.4%) of residents in the Indigenous Peoples Settlements. Analysis of Variance(ANOVA) confirmed that, there were significant differences in the age distribution of residents (F=4.11, p= 0.005). The results also inferred, that a trifling 1.0% of the residents in the study area were high income earners, while 99.0% were low and middle income earners. Housing habitability attributes were subjected to factor analysis to evaluate the factors of housing habitability conditions in the study area. Thus, it was discovered that there existed negative correlation between privacy(va), proxemics and security(vb);(-5108,0.0011). The research also opined that abundant, affordable and reliable energy supply(vh) had positive correlation in all Indigenous Settlements (ve,0.6120,0.0001). Furthermore, the study identified social, location, structural and neighborhood attributes as factors that influenced housing habitability in the Indigenous people residents Settlements. In general, the Study concluded that lack of houses with building codes compliance, absence of building with certified designs and absence of fire safety measures was the highest factor (mean=3.32, standard deviation = 0.334) that influence housing habitability conditions. While the next ranked factor of housing habitability (mean=3.12, standard deviation=0.232) was the lack of access road to most Indigenous Settlements.","PeriodicalId":360552,"journal":{"name":"International Journal of Civil Engineering, Construction and Estate Management","volume":"301 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131144031","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}
