Abstract:

Conceptual cost estimates play a crucial role on initial project decisions although scope is not finalized and very limited design information is available during early project stages. At these stages, cost estimates are needed by the owner, contractor, designer or the lending organization for several purposes including<br>determination of feasibility of a project, financial evaluation of a number of alternative projects or establishment of an initial budget. Conceptual cost estimates are not expected to be precise, since project scope is not finalized and very limited design information is av

Abstract:

Currently, many railway systems need to be upgraded to meet the demand for rapidly increasing railway capability, environmental concerns and customer satisfaction, while there is a lack of the right models and tools required to support the early decision making stage of railway renewal projects. In this thesis, a new railway selection upgrade process is proposed, which aims to support early stage decision-making in railway renewal projects by finding the most appropriate solutions to take forward for more detailed consideration. The railway selection upgrade process consists of modelling, simu

Abstract:

The main objective of this work is to develop models using multivariable regression and artificial neural network approaches for cost estimation of the construction costs of trackworks of light rail transit and metro projects at the early stages of the construction process in Turkey. These two approaches were applied to a data set of 16 projects by using seventeen parameters available at the early design phase. According to the results of each method, regression analysis estimated the cost of testing samples with an error of 2.32%. On the other hand, artificial neural network estimated the co

Abstract:

The infrastructure sector is essential for the social development in relation to for example urbanisation, but the infrastructure sector also has a negative impact on the environment. Infrastructure projects are part of the UN SDG and is an important factor regarding sustainable development. It is therefore important to make sure the development of infrastructure projects are sustainable in all phases. This can, among other things, be achieved through a sustainable project management. However, there is no clear systematic frameworkfor how sustainability can be implemented in the project manage

Population displacement has long been a controversial companion of development. The central tension has been between the position challenging the kind of development that removes people from their homes, livelihoods and communities, and a managerial position that the impoverishment risks of displacement can be mitigated through an effective intervention. Whereas recent research has been devoted to unpacking a rather unsuccessful performance of involuntary resettlement as a mitigation measure, this study aims to question the assumption of mitigation itself by expanding the concept of developmen

Este trabalho descreve um dormente monobloco de concreto protendido, o qual foi projetado para atender as características de uma via ferroviária brasileira. O dormente apresentou comportamento e resistência semelhantes aos dormentes de concreto comumente fabricados em vários países. A fim de verificar e aprovar o projeto, o dormente foi submetido a ensaios estáticos e dinâmicos, segundo as especificações da norma americana AREMA. Verificado e aprovado o projeto, dezoito dormentes foram fabricados sem e com fibras de aço, no teor de 60 kg/'M POT.3' (aproximadamente 0,75 % por volume). Ensaios e

碩士<br>國立中央大學<br>土木工程研究所<br>100<br>Several railway track elevation projects have been completed in Taiwan since 1989. These projects are highly beneficial because they reduce traffic congestion caused by the barriers of rail tracks. The railway track elevation projects of Taoyuan section has been planned and designed to improve the traffic in Taoyuan County; however, the impact of the railway track elevation project in terms of emissions is still unclear. Moreover, the traffic improvement following the railway track elevation project often leads to significant changes in land development and tr

Because of the annual budget limitation, the central government is unable to perform all the projects simultaneously in short term. In the year of 2004,the anterior prime minister, You Si-Kun, emphasized that a project must be implemented according to the priority ranking of government’s planning and approved i

Since the temporary railway construction is a temporary facility, how to evaluate and consider its planning and design before construction and to solve the problems it is going to encounter during construction will have great influence on its construction time and cost. This research first has studied the completed temporary railway construction projects to understand the factors affecting the construction time and cost from the planning

This scheme is to utilize the financial benefit, generated by land development at neighborhood of the infrastructure projects, on to enhance the financial viability of the projects. An elevated railway project at Yuan-Li is used as an example for constructing a model for financial analysis with value added by cross projects. Two major improvements are considered in the model, which is the value added by cross projects and the manager

In addition, this plan is also intended to merge all road signage by constructing new roads under the newly built elevated railway. Based on the environmental point of view, railway infrastructure improvement may be able to reduce the congestion and also emission for the whole Taoyuan County area. But the construction of new roads under it may result conversely for the area neighboring

Since that time, the country has been pursuing an independent policy that promotes democracy and open market economy. However, there are two contrasting features while doing so. On one hand, Mongolia is considered to be a rich country in mineral resource, but the ordinary Mongolian citizen cannot get benefit from its resource.
