The impact on highway construction from highway trust fund leakages

The diminishing financial resources and the growing demand for participation remain the biggest threat to higher education in Ghana. Cognizant of these quagmires and realizing the impact of higher education on national development, the National Union of Ghanaian Students proposed and the government established a special education trust fund called the Ghana Education Trust Fund bill (GETFund) in 2000. Despite these challenges, the GETFund is making significant contributions toward higher education development in Ghana in infrastructure, student development, faculty research, and staff support.

Main Factor

Construction dust falls to the snow cover and the surface of the glacier to form a fouling layer to absorb more solar radiation and reduce the intensity of surface albedo, thereby accelerating the melting of the glacier, which is the main factor affecting the glacial environment in the Highway construction. This article adopts the combination method of wind tunnel experiment and numerical simulation was used to calculate the impact range of construction dust. The results show that with increasing of particle size, the diffusion range of dust decreased while the settlement speed increased. High dust concentration area (> 4mg / m3) is generally distributed within 1000m around the construction site. The specific extension direction is directly related to the local terrain and wind direction, and the height direction is generally not more than 300m. According to the above simulation results, for preventing and reducing the impact of highway construction on the glacial environment, the requirements of route selection and construction dust control measures was put forward, which played an important role and significance in guiding the highway design and construction and reducing the impact of highway construction on the glacial environment.

The Impact

ABSTRACT The Oil Spill Liability Trust Fund (OSLTF) was forged in the legislative cauldron of the aftermath of the Exxon Valdez casualty. However, its genesis really began with Congressional consideration and debate concerning whether to adopt an international liability and compensation regime or improve the unilateral system unique to the United States. The Oil Pollution Act of 1990 significantly expanded the scope of the unique U.S. mechanism, while at the same time it urged the Administration to continue to examine the possibilities of becoming party to an international regime. Ten years after the Exxon Valdez casualty provides a convenient and appropriate time frame for reflection on how well the public has been served by the establishment and implementation of the regime of which the OSLTF is a major element. The impact on various publics served and stakeholders impacted will be analyzed and evaluated. While there are clearly differences in scope, application, and funding mechanisms between the U.S. and international regime, there are substantial similarities in terms of process, administration, areas of concern and interest.

The Impact

The literature mentions multiple factors that can affect the accuracy of estimating the project duration in highway construction, such as weather, location, and soil conditions. However, there are other factors that have not been explored, yet they can have significant impact on the accuracy of the project time estimate. Recently, TxDOT raised a concern regarding the importance of the proper estimating of the lead/lag times in project schedules. These lead/lag times are often determined based on the engineer’s experience. However, inaccurate estimates of the lead/lag time can result in unrealistic project durations. In order to investigate this claim, the study utilizes four time sensitivity measures (TSM), namely the Criticality Index (CI), Significance Index (SI), Cruciality Index (CRI), and the Schedule Sensitivity Index (SSI) to statistically analyze and draw conclusions regarding the impact of the lead/lag time estimates on the total duration in highway projects. An Excel-based scheduling software was developed with Monte Carlo simulation capabilities to calculate these TSM. The results from this paper show that the variability of some lead/lag times can significantly impact the accuracy of the estimated total project duration. It was concluded that the current practices used for estimating the lead/lag times are insufficient. As such, it is recommended to utilize more robust methods, such as the time sensitivity measures, to accurately estimate the lead/lad times in the projects scheduled.
