Ramat Park is one of the popular Parks in Benin City which is in form of a roundabout connecting traffic from Benin City to the North and Central part of the state including Delta state. In most cases, especially on market days, there is a gridlock within the park which necessitates the uncontrolled honking of horns and emission of other vehicular noise in a bid to checkmate reckless driving. Traffic noise was measured within a period of one month using digital noise meter at 10m away from the source of the noise and about 1.2m above ground level. Two traffic models (Rahul Singh Equation and Calixto Model) were used to calculate the vehicular noise level and the values obtained correlated well with the observed values. The plots of the measured and computed noise levels gave Root Mean Squares (RMS) of 0.776 and 0.839respectively.This indicates that the pattern of the scattered plot is narrow and there is a strong relationship between both computed and measured noise. It was therefore concluded that indiscriminate and reckless activities of drivers (especially commercial bus drivers) were responsible for the noise emission while enforcement of traffic laws in the state and relocation of the motor park close to the square were recommended control measures for noise reduction.

The complex environment of the Sun-Earth, which resulted in the spatial and temporal variations of the ionosphere leads to different kinds of effects on human technologies. Man's continuous increasing utilization of space technologies in addressing it's immediate and future needs demand quality research of the space environments, to understand the physics of the interaction of the environment with systems (both space and earth bound), and to develop methods of mitigating the environmental effects. This is one of the reasons Center of Atmospheric Research

Engineering, procurement and Construction (EPC) projects in the oil and gas sector of Nigeria are under-researched. This leaves investors with little or no guide on the cost-overrun risks of oil and gas depot projects. Using the qualitative case study research technique, this study investigated cost overrun in the civil works of a petroleum products depot project in Lagos, Nigeria. The objectives were to ascertain the reasons for cost overrun and the areas of substantial cost overrun in the project. It was found that except for the cost of construction of “gantry” which was under-measured as a result of use of a wrong method of costing, the rest of the major facilities experienced cost overrun with a cumulative difference of 106%. It was also discovered that the cost overruns mainly originated from design and construction activities. The study recommends the timely engagement of consultants to review the conceptual designs of contractors and monitor the activities of EPC contractors for oil and gas depot projects on behalf of clients. Such consultants should not, however, have powers to control the contractors. As much as possible, parties to EPC contracts should use standard conditions of contract that will better reflect their intentions rather than contrive bespoke conditions.

In engineering projects involving the construction of aboveground storage tank big enough to retain and/or accommodate large quantities of petroleum products such as crude oil and condensate, mathematical reduction of obtained field data using condition equation method is always appropriate for an onward monitoring of those structures. This paper demonstrates how condition equation method can be used to adjust geodetic surveying measurements in relation to aboveground storage tank. Accuracy is in the order of σ a = 5.66e-4 and σ b = 1.113e-3 while σ smax and σ smin are 0.0522 and -0.0511 respectively. The results obtained revealed that the method can be satisfactorily implemented for aboveground circular reservoir storage tank structural modelling and monitoring for a similar scenario.

Deformation monitoring is the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of stresses induced by applied loads. Deformation monitoring is a major component of logging measured values that may be used for further computation, deformation analysis, predictive maintenance and alarming. The main purpose of structural deformation monitoring scheme and analysis is to detect any significant movements of the structure. An effective approach is to model the structure by using well-chosen discrete points located on the surface of the structure which, when situated correctly, accurately depict the characteristics of the structure. The problem of Engineering Geodesy is the formulation of the Mathematical model that will reveal the characteristic of the structure being monitored. In this paper, the mathematical model that reveals the changes in shape of a circular reservoir structure is formulated and applied numerically. A numerical solution was carried out using the Mathematical model formulated.
