Role of Simulation in Post Occupancy Evaluation of Hospital Ward Building in Nigeria; State of the Art
Usman, Abdullahi Muhammad1; David Ileza Adamu2
Department of Architecture, Ahmadu Bello University
The occupancy evaluation proposed in this study evaluates space by predicting user behaviour in the space based on the spatial characteristics that have an effect on human behaviour. For this, the main factors that have an influence on user behaviour among the physical factors are defined and implemented in a virtual space. This study examined spatial evaluation methods and a simulation implementation plan based on three factors: “User,” “3D Space,” and “Action.” However, it addressed the theoretical aspects only, which concluded that spatial evaluation can be performed through simulation. Conducting POE has the potential to reveal problems that are not known by the stakeholders involved due to liability and credibility issues. However, POE should be integrated with quality inspections and defect management that occur during the building’s lifetime. Based on this process, an evaluator is able to predict user behavior and evaluate the space. The preliminary conclusion is that if spatial evaluation simulation is conducted based on the theoretical research proposed in this study, effective results could be obtained.

In modeling the impact of volatile organic compound emitted from oil spillage interacting with environmental variable here called air temperature on the eco-system, the method of ODE45 runge-kutta numerical simulation scheme using MATLAB SOFTWARE was used to investigate their qualitative behavior for a period of 360 experimental time in days at an interval of t=0:29:348 in days and observed that the numerical simulation shows that on the base day of the experimental time the two variables maintain their initial conditions and sudden changes down the trend as the volatile organic compound emitted from oil spillage increases monotonically from a value of 12748 in volume on the 29th day to a saturating value of 13699 in volume on the 348th day whereas the air-temperature decreases monotonically from a value of 11.44oC on the 29th day to a negligible saturating value of 0.0083oC on the 348th day. This observation is consistent using the idea of the mathematical formulation for interacting environmental variables of the lotka-volterra ordinarily differential equation. The full novel results that we have obtained have not been seen elsewhere: these have been presented and discussed in this study.

Assessment of Construction Sites Sustainable Waste Management Strategies in Abuja
Mahmud, I.; and Adamu, A. D.
Department of Quantity Surveying, School of Environmental Technology, Federal University of Technology, Minna, Nigeria
Waste management and sustainability are two fundamental underlying ideas that the construction industry must recognise and execute. Nevertheless, doing so may be difficult and time-consuming. To this end, the aim of this study is to assess sustainable waste management strategies adopted at construction sites in Abuja with the view to enhancing material waste sustainability practises adopted by construction firms on construction sites. The study adopted a quantitative research approach with the use of a structured questionnaire, administered to 155 respondents. Of the 155 questionnaire copies administered, 150 copies were returned and used for data analysis, giving a response rate of 97%. The analysis of the data was carried out with the use of percentage, mean item score (MIS), and factor analysis. The study identified six (6) factors affecting the management of material waste on construction sites, of which financial factors (MIS = 4.08) are the most significant factors. Material costs and energy costs were the most important social sustainability factors (MS = 3.80 and 3.80) respectively. Re-imagine and re-design were identified as the most significant strategies (MS = 4.50). The recycling strategy was identified as the most effective strategy (MS = 4.70). The KMO value is 0.655, and the Bartlett’s test of sphericity is significant (p < 0.05). However, it is, therefore, that the adoption of a sustainable building construction waste management process will minimise, reuse, and recycle construction waste to the greatest extent possible to alleviate the construction waste issue in Abuja and Nigeria at large. The major recommendation from the study was that for waste management to be sustainable in the Nigerian construction sector, an upgrade in either the approach or method of application is required.

Department of Geography, Federal University of Technology, Minna
Charcoal production for rural and urban energy consumption is a main driver of forest degradation in the study area and Nigeria at large. The magnitude and relevance of this forest degradation process is likely to increase unless important shifts are made in energy consumption patterns. These highlights the relevance of studying charcoal production as a separate process, therefore this study assessed the impact of charcoal production on forest degradation in Mokwa Local Government Area, Niger State, Nigeria. This study employed both primary and secondary data sources. The primary data sources include questionnaire administration, oral interview and field survey. The secondary data sources used include journals, textbooks, newspapers, unpublished and published theses and the internet. This study revealed that high prices of alternate energy sources for cooking ranked the highest causes of charcoal production with 48.2% respondents, poverty ranked second cause with 31.2% respondents, population growth ranked third with 13.8% and urbanization ranked the least with 6.8% respondents. This revealed that high prices of alternate energy sources for cooking was the major cause of charcoal production in the area as kerosene and gas where very expensive for average household head in the study area. The study also showed that respondents prefer to use trees like Butyrosopermum paradoxium, Dialium guineense, Terminalia glaucencens, Acacia species, no preference and Khaya ivorensis. Other species used in the study area in little quantity include Vitellaria paradoxa, Anogeissus leiocarpus, Bridelia ferruginea, Terminalia spp, and Pericopsis laxiflora. This is because of the unique features of these trees to produce good quality charcoal. The study listed the impacts of deforestation to included loss of livestock pastures (22%), soil erosion (14%), loss of biodiversity (8%), loss of wild food/fruits (4%), loss of medicinal plants (4%), and flash floods (12%). In conclusion, this activity (production of charcoal) will continue to take alarming directions due to the rising demand of charcoal for domestic uses in urban areas of the State and Nigeria as a whole. Therefore, the degraded land could be used to plant fast-growing species for charcoal production to minimize the impact of charcoal production on natural forest.

The study assessed the building maintenance practises employed in universities in Benue State with the view of suggesting measures for effective maintenance management practises in these institutions. Data was collected from 185 members of the sampled institution’s staff and students, with an 89% response rate. A purposive sampling technique was adopted for the study. The analysis of the data was carried out with the use of percentage, mean item score, and Spearman rank correlation. The study identified the current maintenance practises in Benue state’s public universities and renovations were agreed to be the most adopted form of maintenance practise with a (MS = 3.82). The study identified the most significant factor influencing the decision to carry out maintenance work on buildings in Benue State Universities as faulty design (MS = 3.29). The result of the Spearman rank correlation analysis is presented as positive and slightly strong (0.485). The correlation was therefore found to be significant at a 1% (0.01) level of significance (p = 0.00). It can therefore be concluded that a lack of maintenance culture on the part of both governments, maintenance managers, and building users’ maintenance in the study area results in the deferred maintenance of academic buildings in public universities in Benue State. The major recommendations from the study were that the school’s management should employ qualified maintenance personnel to be in charge of maintenance-related issues and that both the management and users should be sensitised to the proper use of public facilities.

Currently, the organisational culture (OC) is treated as the key driver in making decisions in organisations and as a critical determiner of their effectiveness. Due to the lack of studies in OC assessment in Nigeria and particularly in Quantity Surveying firms (QSFs), this study aimed to assess the dominant OC type based on the Competing Values Framework (CVF). A quantitative research approach was selected. The study’s target population was 40, which represents all registered quantity surveying firms practising in Kaduna State. A survey approach and a purposive sampling method were used to collect the data; while the sample size was 28. Organizational Culture Assessment Instrument (OCAI) was adopted to diagnose the organisational culture of QSFs in Kaduna state. The study results were plotted on a graph using the Radar Chart. The perceived current and preferred dominant OC types were assessed, and actions were proposed. The results established that the perceived current dominant OC of the QSFs was ADHOCRACY culture, while the preferred dominant OC was MARKET culture. This article concludes by providing an understanding of the perceived current and preferred dominant OC types for QSFs in Kaduna state. This contributes to the body of knowledge with the areas of OC type and dimensions to be addressed for Quantity surveyors, Academia, and other stakeholders to improve their firm’s productivity and cost-effectiveness.

Eco-Resort: Towards Promoting Yoruba Architectural Characteristic in Offa, Kwara State
Adeniran, T. A.* and Eze, J. C.
Department of Architecture, Federal University of Technology, Minna, Niger state, Nigeria
Ecotourism has become one of the fastest growing sectors of the tourism industry, growing annually at 10-50% worldwide. Nigeria is endowed with several resources and cultural heritage of international importance which can serve for sustainable tourism development. Without cultural heritage, there would not be any eco-tourism. A survey carried out in some rural communities revealed that Yoruba architectural characteristics are deeply-rooted in historical/cultural heritage but suffers either partial or total neglect. This has affected the tourism value of the country. This paper seeks to examine Yoruba architectural characteristic with a view to promote cultural symbolism in tourism buildings in Offa, Kwara State. A descriptive survey method was adopted for the research and a structured observation schedule with selected variables focusing on Yoruba Architectural element/identities was utilized. Data obtained were documented and analysed using Microsoft excel package, 2016. Data presented for this study shows different Yoruba architectural elements adopted in various Yoruba monumental buildings examined. Findings from the study reveal that most architectural elements have significant values that can be exhibited as a tourism product but are either abandoned or acculturated due to poor values for traditional architecture. The study recommends that professionals in the built-environment from time-to-time adopt Yoruba Architectural styles, elements and characters to promote cultural values and also serves as a great source of eco-tourism product for the country.

To develop a practical developmental blueprint which African cities can adapt to transform themselves into prosperous, vibrant and resilient cities. This paper adopts a qualitative research approach by conducting focus group interviews with three experienced civil servants in order to develop a workable blueprint that can guide African city leaders to improve the lives of their citizens. This paper suggests that combining public sector entrepreneurship and civil service reform is a viable strategy to transform African cities. However, two important prerequisites must be in place for success to be attained: Leaders with the political will and moral courage to truly serve their people. African cities must become proactive and rely on the resources, human and otherwise, that they possess to make themselves more liveable, prosperous and resilient; the current popular strategy of relying on foreign assistance exclusively as the way to success is foolhardy and naïve. The road to prosperous, vibrant and resilient African cities is a long and painful one, but one which we must take for Africa to truly achieve its potential. African leaders and its people must be willing to take this hard road of insistence on excellence, meritocracy and vibrant public entrepreneurship and civil service reform for things to getter better.

The study investigated the economic policies of the Nigeria’s government and their impacts on land resources development. The objectives are to examine the basic land resources in Nigeria; review various government economic policies on land resources in Nigeria; and investigate the impacts of government economic policies on land resources development in Nigeria. The study adopted quantitative approach. Primary data were collected using structured questionnaire from management staffs of Ministry of Commerce and Industry from three southwestern states namely: Ogun, Lagos and Oyo. These states are known for the dynamism of land activities traceable to land development which make them suitable as a test bed. There are 7 departments in the ministry, out of which 5 departments are used, which are suitable and useful to the study. These are; Planning, Research & statistics, Investment, Geological science (staff in charge of mining), Administration & supply and Industrial promotion. 2 senior cadre officers in each of the 5 departments were administered questionnaire to and interviewed respectively making a total of 10 management staff from each study areas (Oyo, Ogun and Lagos states). Data measured on the nominal scale were analyzed using descriptive statistics such as frequency distribution and percentages. The levels of importance of identified factors were determined by the magnitude of their frequency counts with the greatest frequency representing the most important factor. Findings revealed that, in Nigeria there is policy inconsistence and policy reversals which have negative effects on the economy. In conclusion, the study identified that workable and stable policies as practiced in the advanced world and made agriculture played important role in their economy in terms of revenue generation can also be applicable in Nigeria.

The activities of construction workers results to accident happening more frequently at construction sites since building construction activities and trades are embodiments of health and safety risks and hazards. The aim of the study is to analyse the risk level of work items in building construction projects. Purposive sampling technique was adopted for data collection. The mean score method was used to analyse the most risky work items in building construction projects, result revealed that lift installation, electrical work, roof work, and steel structure, with mean scores of 4.03, 4.00, 3.95, and 3.80, respectively were the riskiest work items. The risk prioritization number were used to analyse safety risk assessment, result revealed that roof work, steel installation, reinforced concrete and cladding had similar top three critical hazards, fall from high level, struck by falling object and building structure collapse. It was concluded that work-related risk are strongly associated with construction trades, implying that construction safety risk management requires multiple management approaches. It was recommended that different approaches should be applied in the management of construction safety risks across building trades. The study will improve construction safety professionals’ knowledge and awareness on safety risks and will enhance quality and reliability of risk assessment.

Health sector service in Nigeria is by far one of the most important part of complex economic service sector. Preliminary investigation revealed that, there are challenges with the distribution of healthcare facilities in Mubi North Local Government Area. From the 212 sample population, information revealed that Healthcare facilities are often located a distance apart from the people they are meant to serve. Hence, people have to travel long distance to access healthcare Infrastructure. Must of the health centre experience absence or inadequacy necessary facilities like beds, doctors, nurse/health personnel, laboratories among others. Essential services like electricity, water supply, ICT among other are also insufficient in some of the healthcare centers as presented on the analyzed tables in the work. Physical planning principles are not considered paramount in the distribution of the facilities. Hence, care should be taken to ensure that, they are evenly distributed geographically so as to address distribution issue. The range concept has been chosen which specified that the maximum walking distance to health facility should be 800m as specified by Obateru, (2004). Hence, to address Healthcare distribution problems in the study area, Healthcare distribution plan is also prepared, (see proposed plan for health care distribution appendix ii) in addition to recommendation outlined to improve healthcare service in Mubi North LGA.

The operation of industries in the built environment requires collaborative effects of various actors. Investment in this sector of the economy is usually capital intensive and entails concerted efforts of the professionals in order to achieve the successes of construction projects and the desire of the project owner. The early realization of the need for information and knowledge sharing among professionals in the built environment through collaborative effort of professionals is a basic driver and a vital rudiment for assured quality product delivery, cost effectiveness, adherence to ethical standard and nation building. There are cases of increasing trend of building collapse and building project abandonments across states in Nigeria which findings of various earlier studies and reports of committees have attributed to factors as the use of substandard building materials, the none involvement of professionals among others. The aim of this study is therefore to examine the prospect of professional collaborations in the built environment and the challenges of the collaboration with the view to determine its effects on nation building. The objectives are among others the identification of the various professionals in the built environment that need to collaborate to achieve the common project goal of the investor/developer, empirical assessment of the challenges and prospect of professional collaboration in the industry. Structure questionnaires was designed and administered on eighty interdisciplinary professionals on ten project sites across Kogi state, Nigeria. Relative Importance Index (RII) was employed to rank the variables considered as a challenge to collaborative efforts in the industry. The study found that suspicion and the lack of support (distrust), divergent opinion/share goals, problem of mutual coordination and monitoring, model and reward problem are some of the challenges. The study therefore recommended the need for mechanism that could help to solve the identified challenges in interdisciplinary collaborative practices implementation due to its potential for building project performance enhancement and assured standard and timely project delivery.

This paper evaluated and discussed the spatio-temporal trends and patterns of urban expansion in Kaduna metropolis from 1998 to 2013 and suggested physical planning solutions for improvement. The remote sensing, GIS and spatial metrics techniques was applied to evaluate spatial-temporal urban growth trends and patterns to provide information on the extent and rate of urban growth. The spatial metrics was computed based on the remote sensing image classification results to quantify the trends and patterns of growth. The integration of both techniques provided better understanding of urban growth processes and patterns. The results of the findings revealed that the spatial development change in Kaduna metropolis is drastically at a rise from 1998, 2003, 2008, and 2013. Water bodies experience insignificant increase from 1.52161%, 1.38209%, 1.65265%, and 4.23816% respectively as a result of development encroaching wetland within the year under review (1998, 2003, 2008, and 2013). The built up area on the other hand increased significantly from 3.57834% to 16.57835%. There was a tremendous decrease on non- built up area causing disparity as a result of rapid urbanization and other influencing activities in the study area. Non -built up area decreased from 94.90004% in 1998, 88.46415 % in 2003, 85.89385% in 2008, and 79.18350% in 2013 respectively. It was concluded that there is a rapid rise in growth and development in Kaduna Metropolis. Based on the results of the findings of the study it was recommended that the state government should muster the land supply monitoring for the dynamic aspects of urban growth by estimating the current and future supply of developable land to determine which lands are potentially developable according to physical constraints, governmental policies so that the location of current infrastructure could be made.

The construction industry is an essential tributary of the global economy and an important resource in the overall product of the local economies. In December 2019, the construction industry was exposed to a shock beyond the local level as a result of COVID-19, which was classified by the World Health Organization as a global pandemic after its rapid and sudden spread in multiple countries. The nature of the effects of COVID-19 on the construction industry varied according to the diversity of its projects. The pandemic raised many challenges at the level of the workforce, low or halting productivity, production time and costs, as well as disputes in contractual formulas for construction projects. But some of the effects were more severe and caused consequences for all stakeholders in the construction sector. Researchers and those interested in the construction industry have dealt with the repercussions of COVID-19, but most of the publications focused on studying the impact of the pandemic on the local construction industry, so this paper attempts to shed light on the most prominent effects of COVID-19 on the construction industry around the world, and which were repeated with high frequency in previous studies and reports by following the methodology of review, analysis and selection, and then suggesting optimal coping strategies to reduce the damages of these effects.

The aim of this research was to investigate the returns characteristics and the inflation hedging potentials of residential property investment in Abuja between 2012 and 2022. In order to achieve the stated aim, the objectives included: to investigate the average rental and average capital values as well as returns of residential property in the study area from 2012 to 2021; to ascertain the trend of inflation in the study area from 2012 to 2021 and to analyse the inflation-hedging potentials of the investment in the study area. This research work adopted the cross-sectional survey type of design. Primary data used for this study was obtained through questionnaire survey. The data collected was used to calculate the returns. Descriptive statistics was used to analyse the data while the Holding Period Returns formula was employed to determine the returns of the properties. The study revealed that there was a consistent increase in the rate of returns of residential properties in the study area from year to year except a sudden decline in 2019 and 2020. The study also found out that throughout the study period, the actual inflation had been in the double-digit range with the exception of 2013, 2014 and 2015. The study also found out that the returns in the study area indicated a perverse hedge against inflation. This implies that the returns from residential property investment in Phase 2 of the Federal Capital Territory, Abuja, does not have the ability to hedge against inflation. Based on the research findings, it was recommended and concluded that further research be carried out to ascertain the relationship between returns and other components of inflation. The investment information provided in this study has significant implications for both local and foreign investors desiring to invest in the Nigerian property market, with particular reference to residential property market in Abuja.
