Abstract: One of the most important functions of project management is the monitoring and control of the project process. To perform it, Earned Value Analysis (EVA) in project management is a well-known management system to be applicable. This analysis is a very significant technique to measure and control the performance and progress of a project and is used in various sectors. It allows the calculation of cost and timing variances and performance indices and predicts project cost and project duration estimation. In addition, the usage of the correlation between the schedule performance index and cost performance index and the meaning of indices such as budgeted cost of work scheduled, budget cost of work performed, and the actual cost of work performed is illustrated in detail to analyze the performance of EVM application in the project management. Thereby, in this study, some of the work items of a sample project using Microsoft Office Excel were evaluated according to the Earned Value Analysis and the result implies that the analysis helped the project perform better through the cost and schedule indices.

Abstract: Definitions of beauty and space are as diverse as defined by the disciplines in which it plays a fundamental role; from science and philosophy to art and architecture, each field’s definition for the perception of the beauty of space is often simplified or reduced. This consequently denies us access new spaces whose definitions and perspectives, strategies and impacts on human perception of beauty of space are rarely considered in any cohesive manner. The debate, “Perception of beauty in Architecture and human perception of space”. The research tries to reflect upon new understanding to the meaning of beauty in architecture and thus access new definitions and understanding to the beauty perspectives, strategies and processes of perception beauty in architecture. Some works of architecture have remarkable aesthetic value. According to certain philosophers, part of this value derives from the appearance of such constructions to fulfill the function for which they were built. The research digs through the dilemma of form follows function and argues that one way of understanding the connection between function and aesthetic value resides in the concept of functional and beauty together not the idea of function vs. beauty; the paper attempts to offer a better way of understanding it.

Abstract: BIM is regarded as a new problem-solving method in the field of architecture construction. With the continuous development and progress of BIM, it also has a series of impacts on the field of project cost. In this paper, through literature research, expert interviews, questionnaires, data analysis, and other ways, the current front-line AEC (architecture, Engineering & Construction) practitioners were investigated. This paper investigates the understanding of BIM in the field of construction cost and the current development obstacles and makes a cross-analysis of the development obstacles of various industries. It is found that technology is the most important obstacle in technology, economy, society and other factors, and how to solve the problem of model standardization and accuracy is the most important part. In the cross research of technical problems and professions, we found that there are many deficiencies in the modeling function of current BIM software, and there are also some problems in the transformation of two-dimensional and three-dimensional data, which are considered as obstacles of the whole industry. The research results of this paper can be used as a practical reference for future research, trying to provide technical and management solutions for the implementation and development of BIM in the construction cost of our country.

Abstract: With the development of urban construction, it is inevitable that new or expanded highways cross or parallel with existing buried pipelines. The impact vibration caused by the construction of perforated pile foundation of highway bridge is bound to have adverse effects on the safe operation of adjacent buried pipelines. Based on the micro seismic monitoring technique, the characteristics of pile foundation construction vibration is researched. A series of sensors are placed on the surface and adjacent pipelines to collect micro seismic events of impact hammer on different hoisting height and different excavation depth of pile foundation construction. Thus, the wave characteristics, spectrum characteristics and energy attenuation law of microseismic signal are analyzed, and the influencing factors of construction vibration are studied. It is found that the peak value of acceleration vibration in the vertical direction is the largest, followed by the peak value of radial acceleration vibration, the vibration energy decays in power relation with the propagation distance, and with the increase of the pile hole depth, the vibration velocity of the same horizontal distance decreases gradually. The attenuation is related to the geological condition of a certain pile hole depth. The research results have some guiding significance for the vibration control of pile foundation construction.
