Offshore structures, which are placed in the ocean for the exploration and production of resourcesunderneath the ocean floor, are at the mercy of the environment they are subject to by nature. Theseconditions that the structures may face are the ocean waves, wind, tidal, swell and current.Earthquakes and Tsunami waves may also occur in the water in certain parts of the world. For thesurvival of these structures, the effects of the enviro...
The research paper showed that the major causes of boat and ferry accidents in Nigeria include human factor errors, natural factors, and technical factors. The safety of life and navigation at sea are important to coastal, flag states and the entire international shipping community in sustaining the growth of global sea trade. National governments and indeed the Federal government of Nigeria have committed substantial resources and efforts on programmes aimed at redu...
ABSTRACT Building Information Modelling (BIM) represents the formation of digital models for use during the planning, design, construction and operation stages of a facility’s life. Its productivity and economic benefits to the global building industry are widely acknowledged and increasingly well understood. BIM continues to dominate processes across the built environment, as it offers extensive opportunities to drive a more effective and efficient built environment. Yet, despite the obvio...
In this study of designing a wind turbine using wind energy potential, a case of FUTA. Weibull distribution function method was adopt with the help of probability density function and cumulative density function analysis, the wind speed characteristics and energy potential of the study area was investigated using hourly wind speed data that span between 1 and 12 months (1year) and measured at a height of 10 m. Hellmann power law was used to derive the wind characteristics of the study area to...

The project aimed at producing structural design of eight storey hostel. The research was achieved based on the objectives of; developing structural layout from the architectural drawings; analyzing and designing the structural elements with some degree of economic consideration and producing the structura...
Seaport play a very important role in world trade. Efficient ports are known to be the key source of rising integration of global economy. In this paper we shall consider these institutional aspects of improving seaport performance under three convenient headings: 1. Operation. 2. Maintenance. 3. Safety.
This project proposes the use of a propellers to power a lightweight vehicle as a non-conventional means of transportation within the school environment. Propellers work based on the generation of thrust sufficient enough to move a mass (in this case, a lightweight, three-wheeled vehicle) to which it is connected. The propeller powered vehicle makes use of this thrust generated as the basic source of power needed for acceleration. Although there already exist various works on the development ...
ABSTRACT The construction industry is known to be highly fragmented in that it requires the inputs of numerous parties to deliver a project. The fragmentation of the construction process necessitates effective integration of the numerous parties and the major tool for achieving this integration is effective communication. This study investigates the communication tools used in project delivery, key indicators of team integration in construction proje...
Background of the Study: Every construction company all over the world expects not only to break even in every project undertaken, but to also make a reasonable level of profit that will satisfy the owners of the company. This is only possible if the activities involved in undertaking any particular project are optimized, viz-á-viz the factors of time, cost and quality are successfully brought into optimal play, which defines the success of the project. But until construction project...
ABSTRACT The study focused on maintenance management practice in public and private properties, (a case study of selected public and private housing estates) in Lagos state, Nigeria. To achieve this, case study of 10 selected housing estates were carried out by means of structured questionnaires. A total number of 200 questionnaires were administered to the selected estates and 141 were returned and used for the analysis, and this gave a response rate of 70.5%. Th...
The aim of this research is to conduct a comparative study of passenger satisfaction and service quality in Nigeria among the considered airlines (Virgin Atlantic, British airways and Med-view airline) on Lagos to London route/flights. The research was based on assessing the level of passenger satisfaction on the airline service quality attributes/dimensions. The study shows and ranked Virgin Atlantics services first, British airways services second and Med-view airline services third. ...
The aim of the study is to access the economic implication of absence of National carrier in the Nigeria aviation industry. The airline industry is the key drive of the travel and tourism industry and also a major contributor to many countries‟ overall economy through international tourist arrivals and departures. The study estimate the amount of revenue Nigeria is losing to capital flights for not having a viable national carrier over the past ten years that is from 2007 to 2016.Th...
CHAPTER ONE INTRODUCTION 1.1 Background Of The StudyPassengers leaving on a trip normally want to spend as little time as possible in theterminal. They want to have baggage carts readily available, a fast check-in, and little timewaiting before and quick boarding prior to a timely departure. Passengers do not appreciate longline-ups, repetitive security checks, crowded departure areas, line-ups for boarding and a delayeddeparture. The rise in terrorist activity requires more stringe...
Abstract The research was conducted on investigation into papercrete brick, as an alternative to paper waste management in Abubakar Tafawa Balewa University Bauchi. The demand of paper consumption represents a permanent issue in day to day activities which if a holistic approach is not taken to manage it waste effect, there won't be any sustainability achievement. A laboratory approach was employed ranging from soaking, mixing, casting and curing, finally physical and mechanical propertie...
Most cities in Africa characteristically experience peak time traffic due to the commuter lifestyles of urban area residents. Therefore, in the morning roads leading to the central business district of most towns experience congestion while those leading out tend to have free flows. Traditional methods of solving this congestion problem such as additional roadway capacity have proved to be ineffective and overly expensive. Therefore, Solution of this kind of traffic congestion problem calls f...
