Increasing Demand

In the current era of accelerating pace of urbanization, people are also in increasing demand for high-rise buildings. Because of its high height, multiple floors and large load bearing, there is a big security risk for high-rise buildings. Therefore, it is very important to control the technical points of high-rise building construction and strengthen its quality control. Therefore, this paperfirst analyzes the construction techniques of high-rise buildings, and then discusses the quality control strategies of high-rise buildings in order to provide some reference for improving the construction quality of high-rise buildings in our country.

<p><strong>Abstract.</strong> The article focuses on the analysis of the construction technique of the star vault designed by the famous Bohemian architect from the Baroque period, Jan Blažej Santini-Aichel. The vault covers St. Bernard’s Chapel in the Plasy Monastery and represents a masterpiece in Santini’s late career. The authors try to understand its construction technology with the help of modern surveying methods. The shape of the vault structure is complex, therefore a detailed geometrical survey of both intrados and extrados was performed. The data collected in situ, photogrammetric blocks, were used as a basis for the modeling of the vault shape. An accurate 3D model and HBIM of the structure were generated, using a novel Scan-to-BIM process based on the integrated use of a different Grade of Generation and primitive extraction to support the modeling. This survey is part of a program to implement a vault database addressed to detect permanencies and mutations in the construction techniques across Europe, that gives back unexpected, and mostly unknown, richness of vault construction patterns.</p>

Take over-wet soil as research object, this paper presents the results of field test to verify the effect and feasibility of ash mixing method, one improvement technique for over-wet soil, on improving the performance of over-wet fill in construction site. This paper also studies the construction technology of utilization of over-wet fill in moist and rainy areas; determines construction parameters; summarizes construction techniques, methods and standards of quality control preliminary. The results show: ash mixing method can effectively improve the performance of over-wet fill; note that additives and over-wet fill should be fully stirred; this approach also works well for managing viscous silty sand.

Architectural decoration decoration materials are used by people or decorations, the building and space for all kinds of surface treatment, the use of in order to improve the building comfort.In architectural decoration, engineering quality is directly related to the credibility of enterprises and the effect of the project, and use function. In this paper, from the architectural decoration construction technology management and quality control two aspects to discuss. First of all analyzes the optimization measures of architectural decoration construction technology management, the second for the quality control of several factors is analyzed and summarized.

Setting the late poured band is to solve different settlement between high-rise buildings and to settle the reinforced concrete body temperature--contraction stress. In addition, it effectively avoids the harmful cracks caused by the reinforced concrete body. So it is vital to set the late poured band and organize the correct construction. This paper aims at elaborating types of post pouring belt, construction preparation, construction technique, quality and so on.

According to Chinese traditional classification, large-sized jackets weight over 10,000 tons and stand in over 100-meter water. Large-sized jackets are different from the normal in construction tonnage, structural dimension and quality control requirements as well as construction difficulty. More complicated construction technology and programme, higher grade of materials, stricter control requirements on node weld and higher risks all need matched stricter, more meticulous and more comprehensive management in planning and scheduling. Combined with construction of LW3-1 deep-water jacket, this paper describes the planning, tracking progress, process control and optimization.

Economic Developments

High-type roads in Tanzania have been predominantly of asphaltic concrete construction. This ever enlarging and ageing asphaltic road network represents increasing resource requirements on the road agency in the form of maintenance. Limited resources coupled with the ever sky-rocketing costs of petroleum products and the competing demands of social economic developments, presupposes the need to look for alternative road construction technology that is more cost-effective and resource optimising. Experience gained from developed and some developing countries where concrete pavements have been widely used suggests the potential of this type of pavement in many developingcountries. This paper discusses the technical aspects of design and construction- and maintenance-related aspects of concrete pavements. The discussion extends further to highlight issues pertaining to the performance of concrete pavements and strategies for promoting the use of concrete pavements in Tanzania. Conclusions and recommendationsare made with suggestions on how to start implementing the proposed strategies.

Major Disadvantage

Increased structural weight has always been a major disadvantage and probably the main objection to using concrete hulls. Postwar development in materials and construction techniques has led to claims that it is now possible to achieve structural weights equalling or closely approaching those of equivalent steel hulls. After reviewing the postwar material and construction technique developments, this paper compares the structural weight of existing and equivalent steel and concrete barge and pontoon hull designs. It is found that increased structural weight is a dual factor advantageous in some applications but disadvantageous in others, and that despite the postwar developments concrete barges and pontoons are still heavier than equivalent steel hulls.
