ABSTRACT
The study accesses the spatial distribution pattern of boreholes in Damaturu metropolis. The research aim at providing information that will serve as a guide for boreholes distribution planning to the policy makers of Damaturu metropolis. The geometrical data of sixty eight (68) boreholes were generated using hand held GPS receivers, and the attribute data were generated through office records, site inspection and oral interview. The geometrical data, attribute data, and satellite imagery of the study area were used as input data in ArcGIS software. Digital map and spatial distribution pattern of the facilities were produced. The attribute data were linked to spatial data to enable the researcher examine the spatial distribution of the boreholes which in turn revealed their spatial pattern. Queries were conducted to ascertain the pump capacity yield, status, year of establishment (construction), etc. The creation of zones of interest also known as Buffering was carried out to determine the boreholes distribution patterns that are within 500m and 1000m radius from each other, and nearest neighbor index (Rn) was computed. The result showed the distribution pattern is clustered, which concentrated at core indigenous area of the town. It is clear that the policy implementation in the study area is not properly guided by GIS technique; hence there is need for more efficient distribution of boreholes in the non indigenous area of Damaturu town.

ABSTRACT
Urban spatial development with reference to urban residential and recreational planning including development have hugely been class – related in outlook since the beginning of colonial era even after independence. It is true to mention that in many cities of Nigeria, Owerri of Imo State inclusive in the South-Eastern part of Nigeria, the issue of urban development planning and policies have simply been skewed in favour of upper-political and middle class. The above have given birth to the division of the city into different Nuclei and suburbs, the better of which have been developed into Government Residential Area for the bourgeoisie, super rich and government functionaries. There are equally other high class areas which have been developed for the members of the middle class of the society majority made up of the elite class members, the technocrats and the industrialists. There are also some other areas or sections of the city ear-marked for members of the lower class, members of the poor, most of these structures are shantified and poorly built and this have given them the hew of shims or shanty – foron. Some of these shanty towns can be found in uratta, Amakohia, Ogbaku, Umuguma, Okuku areas among others. As a result of this arrangement, there have been exclusions and urban marginalization of these areas in terms of access to the best of social amenities and infrastructural facilities. This usually affects urban social relations and security. So, in this study we shall examine the case of class similarities of urban spatial development and use in Owerri and the different implications it shows for social relations with a view to abridging the gap.

Abstract:
The predominant and frequent abandonment of a construction project is disturbing that it makes several negative impacts to project construction sector, the owners, the built environment and the economy in general. The motivation behind this paper is to review some related literature and find out the different circumstances/causes/reasons and the resultant effects of abandoning construction projects in Nigeria and its consequences in the Nigerian economy with a view to propose a framework for addressing the problem. This paper used an intensive review of related literatures to ascertain the circumstances/causes and effects of construction project abandonment. Forty five relevant articles were identified and fifteen articles were randomly selected, the sampled articles were reviewed and the following were identified as some of the causes of construction project abandonment in Nigeria; inadequate project planning, insufficient fund by both the client and the contractor, inflation, bankruptcy of contractors, variation of project scope, political factor, demise of client, incompetent project administrator, wrong estimate, inadequate cost management, faulty design and delayed payment. The resultant effects include; disappointment of the populace/clients, low living standard, wastage of assets, decreased in employment opportunities, reduction in tempo of development activities, reduction in income reverting to government, difficulty in securing foreign credits facilities. Therefore, government, clients, contractors and consultants/professional were identified to have a significant contribution towards construction projects abandonment in Nigeria. This is because all have in one way or the other not been able to perform their roles effectively and efficiently. Consequently, if this is supposed to be corrected all should adhere strictly to their roles and responsibilities; so that the country (Nigeria) could have a construction projects abandonment free cities.

Abstract
Information and Communication Technology covers any product that will electronically store, retrieve, manipulate, transmit or receive information. Construction projects comprise different stakeholders; clients, consultants, contractors, local authority; residents; workers and suppliers, all with divergent interests in the project which demands heavy exchange of data and information. Thus, the construction industry is one of the most information-intensive industries, and requires close coordination of a large number of specialized interdependent organizations / individuals to achieve cost, time and quality goals of a project. The industry is characterized by inaccurate and untimely communications that often result in costly delays. This research focuses on studying the Use of mobile computing and wireless communication to manage construction site information in Nigerian. A well-structured questionnaire was developed and targeted top management professionals that are involved in construction site activities. A total of 130 questionnaires were distributed between 5 construction companies. The respondents had on site experience and consisted of Site managers, Engineers, Project managers, Architects, Contractors and other construction personnel. Out of the 130 questionnaires distributed, 63 were returned. However, only 45 were valid for data collection, this shows a return rate of 19%. The data received was then analyzed. It was found that Mobile computing usage can reduce travel costs and heavy reliance on meetings before a project progresses. A higher speed of data reception is more guaranteed than the traditional method of information sharing. Also, it improves productivity and collaboration between the project team.

ABSTRACT
Water is essential to life; no living thing can survive without water. Water can occur underground or at the surface. This study is aimed at identifying various problems associated with groundwater exploration and exploitation in Asaba and its environs, Delta State through field work and desktop research. Seven (7) boreholes and well log data were collected from Delta State Urban Water Board and were carefully studied and analyzed. The study revealed that presence of Electromagnetic materials, rugged topography, clustered settlement pattern and cost of survey are the major problems associated with groundwater exploration. The presence of carbonaceous materials (lignite), contact of cyclic repetition of clay and sand, sharp contact or change between compacted and permeable sand formation have been identified as the major causes of lost circulation within the study area. Other problems associated with exploitation of groundwater include pipe sticking, well failure and submersible pump failure. Hence, the study thereby proffers remediation techniques to tackle groundwater exploration and exploitation problems within the study area.

ABSTRACT
The conventional role of the Estate Surveyors & Valuers as provided in the Estate Surveyors & Valuers Registration Act otherwise referred to as Decree No. 24 of 1975 (Cap III laws of Federation of Nigeria in 1990) is familiar to most of us. The Estate Surveyors & Valuers often list his expertise to include valuation of properties, plant and machinery, project and facility management, feasibility studies, estate agency, rating, property development, etc. “Convention” cannot continue to be the norm in an ever changing, globalizing and competitive world. Human quest for survival, improvement, relevance, innovation, competitiveness, etc. make it imperative that once in a while the Estate surveyors & Valuers, like other professional, revisit his/her “Conventional” role and explore ways of reviewing, redefining reassessing and refocusing those roles. This paper examines the role of the Estate Surveyors & Valuers with particular emphasis on housing delivery through the means of public private partnership using Ilorin, Kwara state as a case study. The paper also explains the need for housing and reveals the housing deficit and its causes in Nigeria. It also examines what is expected of Estate Surveyors and Valuers in Public Private Partnership arrangement for housing provision. It comes to the conclusion that the Estate Surveyors & Valuers must “go beyond borders” in the coming years to contribute meaningfully to the ever basic need for housing. The paper also suggests ways by which this can be achieved.

ABSTRACT
Erosion has been identified as the direct cause of environmental deterioration and poverty in many parts of the world. As urban planners who oversee distribution of land among competing uses to attain maximum practicable degree of economy and convenience, the concern is to ensure sustainability of life through effective management and utilization of land, considering it a scarce resource for sustainable development. Questionnaires were administered in the areas affected to source for data. Observation was also employed to measure the length and width of gullies in the areas. Data was presented in tabular for and maps to show the level magnitude of erosion. It was finally concluded that erosion in Gulak is severe and if the community and the government delay action there may be issues of landslides, building collapse and erosion of arable lands. Thus the study after reviewing methods use in controlling erosion, namely; Natural course, radial pattern and the traditional type of drains, and also identifies three different hierarchy of drainages i.e. services mains, secondary mains and primary mains. The study finally recommends, that the natural course methods is most recommended for the study areas as water does not forgets its course/path. Also there is need for awareness amongst the public so that they may be away of attitudes and uses that affects the environment negatively. Finally institutional framework should be put in place for the implementation of the recommendations.
