ABSTRACT

Delay is one of the biggest problems often experienced on construction project sites. Delays can instigates negative effects such as increased costs, loss of productivity and revenue many lawsuits between owners and contractors and contract termination. The aim of this paper is to investigate the causes and effects of delay on building construction project delivery time. Random sampling technique was used in this study. Population sample of 120 was used in this work. A total sample of sixty-five (65) was deployed. A structured questionnaire in Likert scale was used in data collection. There are many factors impact building project that are delayed negatively, however in some of identified factors includes: time overrun, cost overrun, arbitration, wastage and under- utilization of man-power and resources, abandonment of building project, litigation, loss of interest by stakeholders, blacklisting by authorities and decline in reputation. The factors that causes delay of building project would be observed to prevent the aforementioned impact the delay may cause on building projects.

ABSTRACT

The aim of this paper is to identify the existing gullies in Anambra State, examine the causes and effects of gully erosion in the study area and proffer solutions. To achieve the above objectives, both primary and secondary sources of data were collected using questionnaires, online and desk searches respectively. Data analyses were done using statistical and descriptive techniques. The study also identified major causes of gully erosion in the State as high rainfall and lack of good drainage system, while the major effect was observed as Loss of farmland/ Reduction in soil nutrient and agricultural productivity. Various measures proffered to control the menace of gully erosion in the study area include: preparation of geo-referenced survey template for baseline information, with all the existing gullies inclusive, sensitization and awareness campaign on the serious need for massive afforestation, and the Establishment of local works committee/task force to monitor the movement of storm water. This paper also recommends that government should ensure that ecological funds are properly used for ecological purpose

ABSTRACT

The paper addresses the problems of unemployment among architects in Nigeria. Accordingly, emphasis is placed on why Nigerian architects are unemployed and how to make them employable. A well- structured questionnaire which data were analyzed using the mean value and simple percentage were used find out the causes of unemployment among Nigerian Architects. This paper reveals that unemployment among architects in Nigeria is caused by employers’ preferences and Government policies and its poor implementation. The paper therefore recommends proper implementation of Government policies, entrepreneurial skills among architects and proper monitoring of personnel used on sites as ways of reducing unemployment among architectural personnel.

ABSTRACT

 Substantial amount of failures recorded in the Construction industry in Nigeria were as a result of the corruption within the professionals and stakeholders of the construction industry. This warranted an attempt to evaluate the effects of corruption on construction industry in the south western part of Nigeria consisting of the following states: Oyo, Ogun and Lagos. Though corruption seems to be part of Nigerians daily activities especially in public offices and professionals both in the construction industry and other sectors of national development. This study appraises the previous studies relating to construction industry and cases of corruption and determines the causes of corruption in the construction industry of Nigeria to be poverty, excessive love for money (greed), Politics in the award of contract (godfatherism), professional indiscipline, profit maximization by Contractors, quackery, fall-out of endemic societal corruption and favouritism. Most of  Nigerian leaders that were supported to champion national development are corrupt as shown in The Fifty well completed questionnaire retrieved from the respondents, and formed the data that were analyzed by the Relative Importance Index (R.I.I). In addition, the paper outlines the major ways through which corruption mostly takes place in the construction industry. These are bribe by a bidder to obtain planning permit or license, bribe to rig the outcome of a tender, bribe to acquire land, bribe to compromise quality of the project, bribe to delay the project for personal gains etc. Consequently, the paper suggests that to reduce the incidence of corruption in the Nigeria construction industry, the causes as outlined above have to be dealt with decisively by government, contractor, individuals connected with contract awards and by construction professionals, and professional bodies (APBN) like QSRBN, CORBON, ARCON, COREN etc., by sanitizing their members on the need to avoid corruption during professional practices and encourage laws to be enforced on erring members.

 ABSTRACT

The maintenance of building which has been relegated to the background is an essential tool to be considered both during and after construction. This study therefore involves identifying, analyzing, as well as proffering solution to the problems of dilapidation in buildings. Building professionals such as the Architects and the builders should be fully involved from design to the completion stage of the project to provide professional advice and to check contractors and defaulters. A good maintenance policy should be put in place so as to prolong the life span of the buildings. Building maintenance is a subject that has to be considered seriously if building is to live up to its expected life span. Field survey and interview was conducted. Based on this the maintenance of buildings was observed as the major problem were design resolution. Lack of funds, response time to maintain and usage were highlighted.

ABSTRACT

The Geological and Geotechnical assessment of selected gully sites in Lainde-Fulani and environs is presented. Field geological study of the area revealed that the area is underlain by Basement Complex rocks. The soils of the area are products of in situ weathering of the underlying basement rocks.  Results of sieve analyses show that the soils at the gully sites have sorting values ranging between 0.42 and 2.3, coefficient of uniformity values ranging between 3.0 and10 , and coefficient of curvature values ranging between 0.2 and 1.3. These indicate that the soils are poorly to well sorted and well to poorly graded. The plasticity indices values ranges between 11.0 and 29 with a mean value of about 20 indicating moderate plasticity with slight dry strength and easily friable. Values of maximum dry density ranges between 1.83g/cm³ and 2.09g/cm³ at optimum moisture contents of between 7.4% and 11.3% revealing that the soils are generally loose. The hydraulic conductivity and transmissivity values as determined from statistical grain-size method ranges between 3.8×10^-4 cm/s to 6.4×10²cm/s and 3.8×10^-2cm²/sto 9.6×10⁴cm² respectively. These indicate moderate seepage fluxes and adverse pore pressures and are thus erodible. From the results of the study, recommendations for erosion control such as; afforestation, construction of drainages, grouting and concrete rip-raps were suggested.
