Authors:Haruna Baba Bwala, James Bako Kaltho, Jacob Omega Kalat Pages: 1 - 18 Abstract: The imperative of Cultural values on the location decision of home businesses cannot be overemphasized in Nigerian society. Hence, this study sought after the cultural values that influence the location decision of home-based enterprises in Bauchi town neighborhoods. An explorative and questionnaire survey were used to obtain the data. Descriptive and inferential statistics were used to analyze the data. The finding revealed that, Bartlett's test of sphericity at .001 significant level by χ² (153) = 247.128, indicated p < .05, affirms correlation existed between the factored cultural variables. The component analysis reveals that religion culture is one of the major influential factors of location decision in the study area at Kaiser-Meyer-Olkin (KMO) .05 significance level, its value is .740 which is greater than KMO .335. This affirms that a major factor of the location decision of home-based enterprises in the study area is the cultural region belief. Thus this study recommended that people's religion values should be factored in, in formulating physical planning policy regulation to guide the development of the informal sector of an urban economy especially home-based enterprises (HBEs).

Authors:Muyiwa Odele, Nasiru Medugu Idris, Ayo Babalola , M. Modibbo Pages: 19 - 38 Abstract: The fishing and farming are the mainstays of the people of the Niger-delta livelihoods and activities. Unfortunately, these livelihoods have been impacted by the activities of climate change. This study seeks to examine the impact of climate change on farmers and fishermen as well as adaptation strategies in Bayelsa State, Nigeria. The study employed a cross sectional household survey to interview a total of 200 farmers and 200 fishermen from twelve communities in three Local Government Areas of Bayelsa State. A checklist was used to guide the semi-structured interview. Findings of the study showed that 92.75% of the participants had good perception of climate change and its impact on farming and fishing activities in the area. Also, decreased quantity and quality of crop yield with mean values of 3.75 was the most devastating effect of climate change according to the farmers while decreasing fish resources and increasing distance to fishing ground with increasing mean values of 3.72 was the most devastating impact of climate change on fishermen. The most favoured on-farm adaptation strategy by farmers was changing of planting time (92.5%) and livelihood diversification for off-farm livelihood diversification (95%) while fishers also preferred to diversify their livelihood sources to non-fishery activities (93.5%). Both farming and fishing livelihood were found to be moderately vulnerable to climate change impact with overall livelihood vulnerability index of 0.392 and 0.390 as well as -0.086 and -0.089 for the approach index respectively. From this study it is evident that farmers and fishers observed elements of climate change in the study area and refers to the change in climate currently experienced as, “bad” compared to what was experienced in the past. It is recommended that the farming communities should assess their vulnerabilities due to climate change particularly as it affects post-harvest so as to engage relevant authorities to help initiate adaptive capacity. Secondly, the fishing communities should be assisted and provided with the needed support by way of fishing boats and technical skills needed to be effective water navigators.

Authors:Abdurrahman Aliyu Jalam, Auwalu Sani Shehu, Adamu Ibrahim Tafida, Muhammad Ahmad Ibrahim Pages: 39 - 56 Abstract: Bill of quantity remained the major document that offers early cost estimates of construction projects especially in traditional form of contract. It is known for the role of ensuring the achievement of cost, time, and quality performances of construction projects. However, BOQs nowadays were found to encompass errors which if not addressed may affect its sustainability. This research evaluates the causes of errors in BOQs for public building projects in Northeast Nigeria. Quantitative research design was employed where in-depth literature reviews were conducted and questionnaires were used for data collection. One hundred and forty structured questionnaires were administered to quantity surveyors. However, one hundred and twelve were returned and one hundred and five were validly used in the analysis. The relative severity index R.S.I evaluation of the data revealed that; Little/No knowledge of using computer software, Poor communication between quantity surveyor and the client, Inconsistent decision making by the client, Negligence of duties by QSs, and Incorrect dimensions in drawings were the five most severe causes of errors in BOQs. Moreover, the mean relative severity index was found to have influence of 66%. Quantity Surveyors should improve their computer literacy through attending workshops and trainings. Proper line of communications among project stakeholders should be established. Employers should inherit the culture of consistent decision making to avoid mixing up of actions. Finally, all team members involved in the production of BOQs should be up to their responsibilities and improve their services and quality of delivering responsibilities.

Tokan Pages: 57 - 69 Abstract: This study looked into the use of graphite as a material for making crucibles using the clay slip casting process. The investigation included determining the chemical compositions of graphite samples sourced from Sama Borkono in the Warji local government area of Bauchi State, processing the graphite into crucibles using the slip casting technique, and determining the physical properties of the crucible using ASTM standard methods such as shrinkage, porosity, refractoriness, shock resistance, and heat conductivity. The graphite sample's chemical analysis revealed that the beneficiated graphite has a sufficient amount of carbon content (80 to 85 percent) for crucible manufacturing. The percentage shrinkage of the samples ranged from 2% to 7%, according to the shrinkage tests performed on them. Thermal shock testing revealed that all of the samples could tolerate rapid temperature changes when subjected to various temperatures. The samples' refractoriness test revealed that all of the samples can tolerate temperatures of more than 12000 °C. According to the conductivity test, sample B had a decent heat conductance of 1.49 W/mK. Following the tests, sample "B" was discovered to meet all of the requirements for graphite crucible manufacture (high refractoriness, high conductivity, good thermal shock resistance, low shrinkage, and low porosity). A brass crucible was melted to a temperature of 9270C to test the crucible. According to the findings of the study, non-ferrous metals with melting temperatures below 12000C can be melted in the crucible made from sample B. PubDate: 2023-03-17 Issue No:Vol. 15, No. 2 (2023)
Authors:Muhammad Sani Abubakar, Muhammad Magaji Ibrahim, Jibril Abubakar Babayo Pages: 70 - 85 Abstract: Urban sprawl is a result of population growth and human activities such as industrialization and rural-to-urban migration that alter local and regional land use and land cover (LULC) patterns. The purpose of this article is to deduce and forecast the urban sprawl scenario in Gombe metropolis using Landsat satellite data. The collected data was geospatially analyzed to generate landuse and landcover maps, which were then used to forecast future LULC using a CA-Markov model. The results indicate that Gombe metropolis covered 13.812 km2 in 2000 and expanded rapidly to 44.105 km2 between 2000 and 2020. Furthermore, the results indicated that the metropolis would continue to sprawl at a rate of 3.48% per year, resulting in 77.623 km2 of urban land use in 2030. Finally, it is recommended that the government encourage more urban studies that take socioeconomic factors into account in order to ensure proper future planning, growth, and development of the Gombe metropolis.

Authors:Kehinde Alabukun Oyewole, Olusegun Peter Akinpelu, Akinbowale Olukunle Akinola Pages: 86 - 99 Abstract: This paper assessed correlates of motorcycle patronage in Abeokuta Metropolis, Ogun State, Nigeria. Primary data were used for the study. Eight (8) tarmacs were systematically selected for survey in the study area. Using accidental sampling technique, all the patrons willing and ready to fill the questionnaire between the hour of 7a.m and 7pm were sampled. This gave total of 219 patrons as sample size. Data were analysed using Cross-tabulation, frequency distribution, percentage, ANOVA and Relative Importance Index (RII). The study shows that there is a statistically significant difference at p < 0.05 of all the socioeconomic attributes analysed except gender. Results of trip purpose revealed that 42.0% of patrons use motorcycle mostly for trip to work. Trip to leisure was the least (4.6%). The level of patronage varied significantly among the sampled tarmacs with computed ANOVA results of F = 8.489 and p < 0.05. Significant factors influencing motorcycle patronage as perceived by the patrons were ability to evade traffic (MPFI=3.93), bad road (MPFI=3.74), door to door services (MPFI=3.73) and availability and accessibility (MPFI=3.41). It can therefore be established that a long as the identified factors exist, motorcycle would continue to enjoy high patronage as a means of public transport.

Authors:Mohammed Adamu Dogon-yaro, Sulaiman Ibrahim Musa, Kabiru Shehu, Alhaji Hussaini Pages: 100 - 129 Abstract: Flooding is an inevitable worldwide natural phenomenon occurring from time to time, especially in flood prone localities, which can directly harms animals, destroy the environment they live and wreak havoc on humanity. This study has presented a state of the art approach for determining drainage network patterns and causes of floods issues in the study area. The study made use of Shuttle Radar Topographic Mission (SRTM) and Satellite imagery datasets. These images were used to produce the drainage network patterns map, base map, overlaid map of the drainage network patterns and base maps as well as to extract terrain parameters of the study area. Three (3) simple methods of soil types test were used to ascertain soil types of the study area, namely; the squeeze, ribbon and Jar test methods. Therefore, the research findings have provide snapshots spatial relationships between the drainage network patterns and existing features in the study area. The study has also reveals major causes of flooding in the study area, namely; drainage network patterns, terrain parameters, soil types, and human activities such as deforestation, mining, constructions among others. The slope analysis has reveals that most parts of the study area, which is about 184.5ha (72.361%) of the total land-cover are characterized by a flat terrain. An analysis of the results of soil types tests reveal that most parts of the study area, which is about 239.85ha (94.069%) of the total landcover (254.97ha) are mainly made up of loamy soils, which has very low rate of water absorption. Hence, the surface runoff water finds it difficult to infiltrate into the soil, and thus often floods over most parts of the study area. It important to note that the results of this study can serve as a model through which the excess surface runoff water can be properly drained into channels leading into nearby streams or ponds, which can further be harnessed for purposes such as irrigation, ranching among others.

Authors:Mudashir Gafar Olaiya Pages: 130 - 148 Abstract: The concept that architecture is not market driven profession, as stated in the Architect's Code of Conduct on the advertisement and marketing of professional services, is a misconception in today's reality. Given how competitive the design and construction sectors are, planning and implementing strategic marketing in an architectural business is becoming increasingly unavoidable. The use of social media marketing (SMM) as an entrepreneurial marketing technique has increased in recent years, resulting in multitudinous economic benefits for both customers/clients and firms. Despite this situation, there is competitive economic pressure on organizations' survival, and there is little research on the impact of social media marketing on architectural firms' entrepreneurial orientation and economic sustainability. However, the study aimed to close a research gap in Nigeria's competitive economic environment. The study employed a quantitative research approach and structural equation modelling (SEM) used for the inference analysis which focused causal relationship between the variables. The data was collected from the architects in Nigeria's registered architectural firms through a purposive sample technique and a structured questionnaire. The research findings confirmed that social media marketing predict the entrepreneurial orientation and economic sustainability of architectural businesses in Nigeria. The outcome of this research influence educational curriculum development and the realignment of the professional code of conduct on advertising and marketing to reflect contemporary practice.

Authors:O. J. Oladiran, A. A. Soyingbe Pages: 149 - 166 Abstract: The minimization effectiveness of any framework can be determined by subjecting it to objective assessment on real-life projects before it can be engaged as a reliable tool for practitioners. This study is an objective validation of a framework for materials waste minimizations (FMWM) on construction sites. The specific objectives are to: refine the structure of the FMWM; assess the FMWM; evaluate its effectiveness; and determine implementation strategies of the FMWM. Cross-sectional survey and pure experimental research designs were used among professionals and construction projects in Lagos State. Data were collected using focus group discussions, interviews and site evaluation; and analyzed with descriptive and inferential statistical tools. The findings reveal that the FMWM is appropriate for material waste minimization with the overall effectiveness of 4.09%, which could be enhanced when the FMWM is used at all stages of construction projects. It implies that construction material waste can be reduced when the FMWM is adequately engaged. It is recommended that professionals should adopt the FMWM for site operations on their projects. This can be done by head offices mandating site teams to apply the FMWM on sites and requesting its inclusion on site reports. PubDate: 2023-03-17 Issue No:Vol. 15, No. 2 (2023)
