Department of Surveying and Geo-Informatics, Federal Polytechnic, Bauchi, Bauchi State
This paper is aimed at mapping flood vulnerable area of part of Rafin Zurfi and Gwallameji for effective disaster management using geospatial application. Lack of awareness on the danger of flooding leads to erection of building at the banks of the river and improper waste disposal by the people which are one of cause of flood within the study area. Therefore this paper highlighted some of the causes, types, effects and control measures of flooding. Satellite imagery of the study area was downloaded, Georeferrenced and digitized. The spatial data was acquired using total station and the average heights of water using a meter road. The volumes of the water for the period of three months were determined, and the acquired field data were processed, analyzed, queried and the streem was buffered using the proximity analysis tool in ArcGIS 9.2 version. A digital map showing the buildings that were prone to flooding was produced. It is recommended that authority concerned should initiate public awareness to that occupant of such buildings on the dangers causes, effect of flooding.

A STUDY OF THE QUALITY OF PROPERTY VALUATION REPORT IN KADUNA METROPOLIS
Estate Management And Valuation Department, Nuhu Bamalli Polytecnic, Zaria
The study examines clients’ perception of the quality of valuation reports in kaduna metropolis with a view to examining their satisfaction level and thus improving on the quality of the valuers’ reports. The survey method employ the use of self administered questionnaire coupled with interview to obtain the relevant data. A total of 15 Banks and 20 estate surveying and valuation firms were studied. Data collected were analyzed using tables and relative importance index. The result of the examination of 18 valuers’ reports in comparison with the standard expected shows that valuers’ reports were meeting the standard. The result also showed 53.3% of the banks are at least satisfied with overall contents of their valuation reports. However the examination of clients’ needs revealed that they would prefer to see more details on the reports. The result shows that “clients demands more information on the larger property market and valuation calculation to convince them on how the valuers arrived at the value; a portion stating the complexity of the market and the position of the property in the market; more emphases on the analytical aspects of the valuation and the estate surveyors and valuers should state how certain they are about the valuation figures”. The study concluded that there should be greater understanding between the clients and estate surveyors with respect to the needs of the clients in the area of valuation reports as well as greater understanding of the limitation of the value figure.

An institutional planning or campus master planning is a recent phenomenon in Nigeria when compared with other urban and regional planning designs. In Nigerian institutions of learning, the challenges of circulation, provision of recreational facilities, working and studying facilities for effective Research, teaching and learning have become prominent. These challenges lead to weak attainment of vision and mission, community services and deployment of technology. This paper intends to educate audience on the goals/factors of Institutional Master Planning (IMP), concepts and missing link in sustainable physical development of Tertiary education in Nigeria. The paper review revealed that, IMP in Nigeria tertiary education could not achieve sustainable learning environment due to missing links among which include; poor financing, weak legal backing and political will for implementation, poor coordination and lack of understanding by the institutions administrators. Another missing link is domination of IMP committees by bureaucrats rather than professional experts in decision making, design and implementation. The paper recommends that IMP decision makers in Tertiary Institutions should be reformed to consist of professional experts in the field to proffer workable strategies (financing, designs, legal and implementation) to achieve the goal of successful tertiary education in Nigeria.

Professional practices play significant economic and social roles in Nigeria. However, their performance of these roles is often constrained by succession difficulties resulting from inadequate attention to succession planning. This study investigated barriers to succession planning in family businesses in professional practice in Nigeria through in-depth interviews of firm founders. The objective was to ascertain the factors which constrain the firms from engaging in succession planning. Findings indicate that the barriers to succession planning operate at the levels of the founder, the potential successors, and the firm. They include founders’ ignorance and unwillingness for succession planning, unavailability of a potential successor, and the prevalence of sole-proprietor firms. Further, customs and traditions influence succession planning but their role as a constraint is not definitive. The most significant barriers are those relating to the potential successors and the firm founder. Thus, notwithstanding barriers, firms will still engage in succession planning if there is a willing successor, the founder is desires succession and is willing to plan for it.

*Civil Engineering Department, College of Science and Engineering, Landmark University, Omu-Aran, Kwara State.
Concrete is regarded as the most widely used constriction material available nowadays because it can be prepared from locally available material , and also because of its flexibility in handing and placing .despite all its advantages, when it come to attaining the desired strength, it is the most unpredictable material encountered ever. Extensive research work and experiences. Gained over the years have shown that quality and durability of concrete depend mostly on the properties of its constituents, and at the same time, mix design, method of preparation, placement, curing condition, etc. This study examines the production of lightweight concrete by using plastic water as coarse aggregates, and also analyzed the effect of replacing material aggregate with plastic aggregate on the workability and compressive strength of structural lightweight concrete with ordinary Portland cement (OPC). The study also examines a new potential technique to produce structural .lightweight concrete, and to encourage the constitution industry to make it as a new approach for future use in budding and construction sectors.

A good combination of transport mode is vital in any community is that need an efficient transport system. A community, irrespective of its socio-economic status, should have substitute within the public system of transportation available to everyone and “Door-to-Door” inclusive. In most developing countries, two and three wheeled vehicles are part of the essential mode of transportation. The case is not different in Nigeria and Kaduna state in particular. The three wheeled vehicles population popularly called the “Keke” NAPEP which has come to replace the popular Okada needs to be properly organised. This paper examined the scenario of local transport development with regards to the operation of the three wheeled vehicles as public transport system mode in Narayi community. The three wheeled vehicle is classified as a motor vehicle composed of a motorcycle fitted with a single wheel sidecar or with a two-wheel cab, operated as a public transport for a fee. Studies elsewhere has shown that the presence of various three wheeled vehicles has enhanced public transport in many cities of the World but the problem lies with inadequacy of national or local policy defining the creation of routes, its operation and physical design and usage. The sample size used for the users is 375 and 50 for the operators. Systematic sampling technique was used so that after every 40th house hold, a household was administered a questionnaire and for the vehicle operators, accidental sampling technique was utilized. The result shows that though the modes are a welcome development by users. The area is faced with lack of good alternative roads and negative attitude of operators. The principles of collective efficiency, the clustering of all the stakeholders become imperative for support for the achievement of common goal such as creation of routes, designated areas of operation and parking for the three wheeled vehicles operators.

Data acquisition is fundamental to digital mapping. They exist in several topographic data collection techniques such as; Ground Survey, Photogrammetric, Graphic Digitizing, Remote Sensing, and Intergrated Approach. In this research, Ground Survey method of data acquisition was adopted. The research site is located in Damaturu, the Yobe state capital. It has an area of about 15.823 hectares with a perimeter of 1,603.93 meters. Five property beacons were used for the execution of this research. Kern DKM2A theodelite and its accessories were used for perimeter traversing (14 stations), while detailing and spot heighten were carried out using Leica TCR403 Total station instrument (2,726 points were observed) in coordinate mode. The traverse was computed using scientific calculator and the data from the total station instrument was downloaded using construction data manager software. The linear and angular misclosure were found to be 1/9,000 and -57” respectively. All the observations were within the allowable limit of third order job. Traverse computation program was developed and run using Star*NET Software. The computed coordinates of the corner points were compared with the coordinates obtained by the total station instruments. The data were analyzed. The final plan was produced using AutoCAD software at a scale of 1:2,500 and 1:1000. The availability of digital survey equipment has no doubt; improve the production efficiency of surveyors.
