PROBLEMS ASSOCIATED WITH THE MANAGEMENT OF AIRPORT FACILITIES: THE CASE STUDY OF MURITALA MUHAMMED AIRPORT, LAGOS, NIGERIA
Department of Estate Management, Federal University of Technology, Akure.
Airports are very essential to air transportation and play critical role in connecting people and goods between locations as no two locations can effectively relate without adequate transportation. The airport is thus described as a “business card”, a major point of attraction and an indicator of the level of infrastructural growth and management of a country. In line with the foregoing, the study assessed the problems associated with the management of airport facilities using Muritala Muhammed Airport, Lagos as a case study. The target population for the study are the facility managers/concessioners engaged in the airport for the management of the various services in the airport. Data was collected through the administration of structured questionnaires and analysed using descriptive statistics, weighted mean score and factor analysis. The study noted that the mode of facility management practice is directly related to the nature of ownership and operation of the airport which indicated the use of concessioning combined with public management practice. The services mostly provided in the airport includes information management; building and property management; civil services; procurements and logistics management; technical services, infrastructure, commercial and space management. The results of the factor analysis show that the problems associated with the management of airport facilities were suppressed into four (4) components with a cumulative percentage of 78.972. It must be stated without doubt that the problems associated with the management of airport facilities must be critically looked into towards ensuring adequate performance, increase passenger satisfaction and provide an environment for safe, secure and economically viable air transportation.

Commercial lands in most Nigerian urban centres have sprawled and converted adjoining residential land uses in a manner in which residential properties are significantly affected by such changes. This led to inadequacy of parking lot, rising residential rental value, abuse of land, traffic congestion in the residential areas and degradation of urban quality. This paper therefore, aim to analyses the urban land use change trends; specifically adjoining residential lots taken up by commercial uses; with a view to consider it effect on formal housing delivery in Bida town, Nigeria. This research work focus on the fringe of the central business districts, like Gbagbara avenue, Esso high way, Estu Masaba road and round-about spot across Bida cinema down town of the metropolis, where it has been observed of steady conversion in residential land use to various uses, commercial uses in particular. In the recent time, there are noticeable increasing economic activities along the intra-city roads in Bida due to failure of the multi-nucleated central business districts to contain the increasing demand for commercial premises such as: office space, shopping plaza and car parking space; thus firms eventually have the incentive to move into the residential areas. This trend is supported by classical urban economic theories which confirm that as economic activities grows over time; other areas closest to the central districts would tend to absorb the emerging business activities. The sources of data for the study were primary source via interview and administration of sets of questionnaires; also publications, journals and internets form the secondary source. Simple random sampling was adopted in order to analyse the extent at which residential land use converted for commercial uses in the selected residential neighbourhoods of the town. The study indicate that profit maximisation arising from the increasing demand for commercial premises, physical obsolete nature of residential properties, are contributing factors that give rise to sudden land use changes from residential to commercial in Bida urban. The findings also indicate that the manner of urban land use change is completely out of the scope established by land use regulations. The study concludes that with high pressure on commercial properties in the metropolis, the residential property market is adversely affected which caused a turn-around on commercial properties development thereby reducing the housing stocks, rising residential properties rental values, physical development challenges, land uses control challenges and abuse of land. The paper recommends that the land use policies be revived and introduction of a data base of real estate transactions.

This work on impact of slums development on environment in Masaka, Karu L.G.A., of Nasarawa State, Nigeria. The objectives were to identify the indices of slums in Masaka; determine the causes of slums development, examine the effects of slums environment on people; examine factor leading to slums development and to identify the problems militating against control of slums in Masaka area. To obtain adequate data, both primary and secondary sources of data were employed. As to the method of data collection, field observations, questionnaire and interview methods were used. The results revealed that slums in the study area have certain feature which include high rate of rural – urban migration, poorly designed houses, poor drainage and sewage disposal system, resulting in unskilled, unemployed and low income earners ( men & women). There is need for the government to control the sale and resale of land and enforce compliance with building specification (code) by town planning authority. Slums can be improved by providing good roads, drainages and sewage disposal system and through the provision of basic amenities such as water, electricity and access roads.

Department of Architecture, Faculty of Environmental Sciences, University of Jos, Jos
This paper is aimed at addressing the car park shortage problem of the Central Business District, CBD, of Jos, the Plateau State capital, Nigeria, West Africa. The car park dilemma has become a blot in the landscape of the city centre as a result of its gross inadequacy. A study of the city centre’s car park problem revealed a continuing, incremental trend whose magnitude cannot be easily quantified. The purpose of this paper is to put forward a plausible, sustainable solution which would address the parking problem such that it is contained as the need arises irrespective of the developmental stride of the city centre. This was achieved by undertaking a field investigation and an Outline Architectural Design proposal of a prototype car park facility in the form of add – on – module to address the exigencies of sustainability and adaptability. The proposal also sought to address the address the unpredictable but surely increasing future car park needs. Through this means emerged a blueprint for means of addressing the present car park problems and also the future requirements within the framework of socio – economic, environmental and sustainability needs.

One of the major environmental problems associated with the physical environment in Kebbi State is desertification. However, the rural nature of the State suggests that a large population depend on the natural environment for their livelihood. The control of these basic needs from forests has made the strict enforcement of exploitation regulations very difficult. To investigate these problems, mixed approach having both qualitative and quantitative data from questionnaire, in-depth interview (IDI), focused group discussion (FGD) and Normalized Differential Vegetation Index (NDVI). The study used the systematic sampling method to select communities for the in-depth interview (IDI) and focused group discussion (FGD). In the case of selection of people for IDIs and FGD, the study selected participants using purposive sampling method in view of the fact that respondents are strictly stakeholders in forest management. Questionnaire was administered at Ministries, LGCs and Zonal Forestry Offices. Purposive sampling method was also used for the selection of forests for satellite images for 1990, 2005 and 2015 using Normalized Differential Vegetation Index (NDVI). Data was analysed using descriptive statistics. The qualitative data obtained from FGD and IDI were processed by the use of content analyses. However, the study also analysed the FGD and IDI data using quantitative method to compliment the content analysis. Results show that the State is badly deforested hence leading to some recommendations such as ensuring that, all forest resources are taken into account and considered valuable worthy of protection and preservation. Also review all forest policies and management systems already implemented.

The study uses remote sensing and Global Information System (GIS) tools and techniques to examine the trend and rate of change in Land Use and Land Cover both spatially and temporally in Minna and environs in Niger State of Nigeria. Satellite Imageries were obtained from Land Sat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) covering three epochs, 1990, 2001 and 2018. Four major classes were categorized to include Vegetation, Bare soil, Built up areas and Water body. ArcGis 10.1 software was used in analyzing the rate of change in a GIS environment. The result shows that at 1990, vegetation constitute 48.84% of the land cover followed by Bare soil,43.86%, built up areas was 5.15 % while water body was 2.15% . The 2001 image shows that vegetation, water body and built up areas all increased to 54.85%, 2.85% and 8.39% respectively while bare soil reduced to 33.91% in 2001. The result shows a change in 2018 with vegetation dwindling to 29.85% from 54.85%, water body also reduced to 1.85% while bare soil and build up areas increased from 33.91% and 8.39% in 2001 to 50.06% and 18.24% respectively. The study concluded by recommending government to strengthen the capacity of urban development boards to ensure compliance to building design that will protect green areas, increase public awareness on the need to switch over to sustainable cooking fuels aside fuel wood and to encourage agricultural mechanization to increase food supply without depleting forest resources.

Problems associated with water quality in the study area are commonly attributed to nutrient, chemical and pathogen loadings into Suleja Dam as a result of point source and non-point source activities. Therefore, it was imperative to evaluate the effects of agricultural activities on water quality in Suleja dam, Niger State, Nigeria. The materials and methods utilised for this study were water samples, field observations, photographs and questionnaire administration. Data were analysed using statistical techniques such as the mean, frequency percentage and Analysis of Variance. The result revealed that the nitrate for the study area during the rainy season were very high above the permitted level (50mg/l) except sample X3 (23.8mg/l). The finding shows that fluoride was present in all sample points and two samples (X5 and X6) exceeded the acceptable limit of 1.5mg/l. The highest E.Coli value was located in sample point Y4 with value of 74cfu in dry season and the least was located in sample point X6 with value of 5cfu in rainy season. The result also revealed that there were presents of bacteria (Coliform and E.Coli) in all the sample points during the wet season which was as a result of human and animal faeces contamination. Incidence of health challenges in Suleja Metropolis showed cholera, diarrhea and typhoid are on the increase and this is attributed to poor drinking water quality from Suleja dam that has E.Coli of 74cfu which is greater than the accepted level. Year 2015 has the highest Diarrhea occurrence in the study area with 1,283 occurrence, 2014 has the highest Cholera occurrence with 198 and 2018 has the highest Typhoid occurrence with 273 in the study area. As revealed in the study, awareness against the high usage of fertilizer and pesticide around the dam ranked the highest with 173 (53.9%) respondents, disallowing the dumping of fish and poultry waste water in the dam ranked second with 69 (21.5%) respondents and the least was the enforcement on the Reduction of fertilizer usage around the dam with 39 (12.1%) respondents. This implies that were good preventive measures against the effect of agricultural activities on water quality in the study area. In conclusion, agricultural activities has both direct and indirect effects on the quality of Suleja dam and is among the leading causes of water quality degradation, mainly as a result of the excessive use of agrochemicals. Its therefore recommended that the conditions of Suleja dam can fluctuate periodically, so water quality of this dam must be measured regularly to observe trends.

The paper assesse the quality of sandcrete hollow blocks in some selected Local Government Area, (Igabi, Kaduna North, and Kaduna South) in Kaduna Metropolis. This is with the view of producing quality sandcrete hollow blocks in the Metropolis. Experimental research design was adopted for the study. Twelve (12) sandcrete hollow blocks industries were used for the study using purposive sampling method for the selection. Samples of sand and sandcrete hollow blocks 450mmx150mmx225mm (6”) were obtained for laboratory tests on specific gravity and compressive strength analysis. Results obtained were compared with the standard set by the Nigeria Industrial Standard. The specific gravity of sand 2.5–2.7and 28 days compressive strength of the 150mm sandcrete hollow blocks recorded average strength ranging from 1.84 N/mm2 – 1.95 N/mm2. The compressive strength of the sandcrete hollow blocks was less than 2.0N/mm2 in eleven (11) sandcrete hollow blocks industries and one (1) satisfied the NIS specification. The findings revealed among others that the mix ratio used by the sandcrete hollow blocks industries result to low quality blocks. The study therefore, recommended that the importance of adhering to standard specifications should be emphasized and sticks penalties to melt out to erring producers by the Nigeria Industrial Standard Organization.

Geographical information system (GIS) is the technology that deals with the acquisition, storage, processing, presentation and dissemination of spatial information. It is an energetic and multipurpose technology that can be incorporated in managing both spatial and attribute data in text and graphic form thereby making it most apt for land administration purposes. This paper examines the effectiveness of geographical information system on land administration in Kaduna State. It maintains that the adoption of Geographical information system (GIS) technology in land administration will facilitate timely title registration, provide tenure security, ease land application processes and information sharing, facilitate land transactions, reduce corruption associated with land dealings, create efficient land markets and serve as a decision support system to government at all levels in formulating policies relating to land. The paper therefore advocates for the immediate computerization of all land records using Geographical information system (GIS) technology as imperative for efficient and effective urban land administration.

ACHIEVING ZERO ELECTRIC LIGHTING DURING THE DAY IN BUILDINGS IN NIGERIA
Department of Architectural Technology, CES, Hussaini Adamu Federal Polytechnic, Kazaure, Jigawa State, Nigeria.
In Nigeria, like in many parts of Africa, the electric power sector has been bedeviled with many stubborn problems that have seemingly refused to be solved resulting in power outages thereby plunging building occupants into darkness and robbing them of the opportunity to carry out legitimate and profitable power related activities. The problems in the power sector are obvious yet some designers and developers have continued to design and produce building outcomes that rely heavily on electric power to light building interiors despite the abundant sunlight that nature has blessed the country with. It is disturbing to note that in a bright sun-bashing afternoon some activities in buildings such as reading, writing, cooking, washing etc. could not take place effectively without turning on the electric lights. This paper seeks to create awareness and alert designers, developers and building owners that interior space could be lit naturally which offers, on a platter of gold, zero running cost. To do this, the phenomenological approach for evaluating problem based learning using case study and observation tools were used. Three buildings A, B and C (one-bedroom and two three-bedroom bungalows respectively) were selected. The selection was based on the fact that they are among the commonly found residential buildings in our ever growing towns and cities across Nigeria. The day lighting conditions in all the interior spaces were observed, floor areas were measured and the occupants were asked if each space was bright enough for human activities intended in such spaces. Data were collected and presented. After simple mathematical computations, the results show that in Buildings A and C the percentages of floor areas with good day lighting were 49.72 and 65.36 respectively. While in Building B, all interior spaces were adjudged to be adequately lit naturally.

BIM proves to be beneficial to building clients and facility managers in terms of increasing building performance, automatic corrections when changes are made to the design, earlier collaboration of multiple design disciplines, automatic extraction of cost estimates during the design stage, discovering design errors and omissions before start of construction and so on. This research was aimed at identifying the imperatives of BIM adoption in the Nigerian Construction Industry and also pin point the most beneficial stage if BIM is embraced in the construction processes so that effort can be concentrated there when adopting the technology in the Industry. A quantitative approach was undertaken for this purpose, from the survey conducted using a semi structured questionnaires the study was able to identified twenty four (24) benefits of BIM within the Industry and with the help of thematic analysis approach they were later categorized into four (4) primary constructs. Thus; are Pre Design Stage Benefit (PDSB), Design Stage Benefit (DSB), Construction Stage Benefit (CSB) and Post Construction Stage Benefit (PCSB). From the analysis, It was observed that Design Stage Benefit (DSB) was ranked highest with 4.35 mean score as it tends toward high and extremely high. This emanated from the respondents’ view as a result of the BIM to allow for earlier collaboration of all design disciplines to make inputs in one another’s work which subsequently helps minimize errors and omissions. Similarly BIM enables consistency of all working drawings to the design intent and allows for automatic corrections when changes are made in the design process and provides opportunities to review alternative options.

Industrial activities is crucial to man’s existences for the provision of basic needs of man i.e. food, shelter and clothing but the strategic location of industries away from human habitation is also as important as the existence of industries. The industries and it activities in complementary with its locations, generate hazard to humans, the properties in line with value or values within the neighbourhood in aspect of polluting of environment. In Nigeria, government (Federal/ A state) policies to this effect have seemed perfect but there is still the lingering problem of pollution from industries affecting daily existence of humans and reduction in ;property value due to non – adherence to such policies as in the case study area of Lagos state, specifically Ogba area. A sample survey of 80 respondents/stakeholders was taken and using descriptive tools it revealed at a glance that there is significant impact of the pollution of the industries in Ogba on property value and lives of the residents in the neighbourhood. There should be a regulation that focus on pollution of these industries with their residential neighbourhood in the state by ensuring cleaner production and environmental impact analysis if relocation is not an option.
