The article presents the questions of reviewing models and mechanisms of public administration in the procurement of goods, works and services in the field of construction. A comparative analysis of the types of public procurement mechanisms in construction, based on a set of features, has shown the superiority of a centralized type of mechanism that facilitates the introduction of efficient and flexible procurement methods, for example, the conclusion of framework agreements. The author’s vision of the mechanism of state building purchases, in the form of a conceptual model and system differences, is proposed. It is determined that a decentralized model of public procurement management involves the independent implementation by purchasers of procurement, that is, allows each customer to procure goods, works and services in the field of construction. The centralized model of public administration is characterized by the implementation of public procurement in order to provide the general needs of a single body on public procurement, that is, customers commission the implementation of public procurement on their behalf, a centralized body. According to the combined model of management, public procurement in the construction industry takes place under contracts implemented under the centralized model, and the direct ordering and receipt of goods, works, or services takes place according to the rules of a decentralized model. It is noted that according to the system-wide understanding of the mechanism of public administration in the procurement of goods, works and services in the field of construction, it represents a set of specialized management technologies (methods, techniques and tools) that ensure the organization of the process of public procurement of construction products by authorized agents. The direction of this process is determined by the need to implement the principles of vali- dity and innovation, fair choice of the best bidding, prevention of corruption and ensuring the high efficiency of the implementation of public public procurement.

In order to improve the durability of the asphalt pavement on a cement concrete bridge, this study investigated the effect of the modulus of the asphalt mixture at the bottom layer on the mechanical response of bridge pavement, along with a type of emerging bridge pavement structure. In addition, the design method and pavement performance of a high-modulus asphalt mixture were investigated using laboratory and field tests, and the life expectancy of the deck pavement structure was predicted based on the rutting deformation. The results showed that the application of a high-modulus asphalt mixture as the bottom asphalt layer decreased the stress level of the pavement structure. The new high-modulus asphalt mixture displayed excellent comprehensive performance, i.e., the dynamic stability reached 9632 times/mm and the fatigue life reached 1.65 million cycles. Based on the rutting depth prediction, using high-modulus mixtures for the bridge pavement prolonged the service life from the original 5 years to 10 years, which significantly enhanced the durability of the pavement structure. These research results could be of potential interest for practical applications in the construction industry.

For a competitive low pressure axial fan design low noise emission is as important as high efficiency. In this paper a new design method for low pressure fans with a small hub to tip ratio including blade sweep is introduced and discussed based on experimental investigations. Basis is an empirical axial and tangential velocity distribution at the rotor outlet combined with a distinctive sweep angle distribution along the stacking line. Several fans were designed, built and tested in order to analyze the aerodynamic as well as the aeroacoustic behavior. For the aerodynamic performance particular attention was paid to compensate the influence of reduced pressure rise and efficiency due to increasing blade sweep. This was achieved by a method of increasing the blade chord depending on the local sweep angle which is based on single airfoil data. The tested fans without this compensation revealed a significant noise reduction effect of up to approx. 6 dB(A) for a tip sweep angle of 64° which was accompanied by an unsatisfactory effect of reduced overall aerodynamic performance. The second group of fans did not only confirm the method of the aerodynamic compensation by a nearly unchanged pressure rise and efficiency characteristic but also revealed an increased aeroacoustic benefit of in average 9.5 dB(A) compared to the unswept version. Beside the overall characteristics the individual differences between the designs are also discussed using results of wall pressure measurements which show some significant changes of the blade tip flow structure.

The pop-up architecture (or landscape architecture) becomes popular nowadays. Some highlights include annual architecture program such as the Serpentine Gallery Pavilion at Hyde Park, London; MPavilion in Melbourne; MoMA PS1 and Heart Sculpture in New York. Many of these pop-up architectural works have been designed by world renowned architects, such as Zaha Hadid, Rem Koolhaas, Hezorg and de Meuron, Jean Nouvel, Toyo Ito, SANAA, Shigeru Ban, BIG, etc. And many of these designs reflect innovative thinking that changes the professional world of architectural design. But above all, these pop-up architectures were created in responsive manner to the urban community and the community controversially has good response to this type of architecture. In the other words, pop-up architecture is the way the architects touch the heartbeat of the cities, make them livable for all. Ho Chi Minh City has its own types of pop-up landscape architecture, whereas this paper intends to explore in two case studies: Nguyen Hue Floral Boulevard and Nguyen Van Binh Book Street. Nguyen Hue Floral Street is celebrating now its twelfth birthday in the city. Nguyen Van Binh Book Street has just passed its first anniversary in 2017. Both cases live its own story behind the scene about how livable a city could be through place-making by architecture and landscape design. Throughout these cases, we would like to find out how this type of pop-up landscape architecture being realized and become popular in Ho Chi Minh City, and how it is devoted to a livable city for all.

<p>Urban Ensembles explores the way in which landscape and architecture can be employed together within the design of a steep, urban site. Lyttelton is a small port town on the border of Christchurch, settled in the foothills of a harbour formed by a major volcanic eruption. This rugged setting, with steeply sloping urban terrain, presents an interesting challenge when designing an urban development. The site was badly damaged in a series of earthquakes in 2010-2011, and many of the town’s oldest buildings, heritage structures dating back to the colonial settlement era, were destroyed. This has left a void in the heart of Lyttelton, and caused the loss of much of the tourism business that the town relies upon for its income. This thesis takes a methodological approach to the design of landscape architecture on such a challenging site. A range of techniques are explored, drawing from both landscape and architecture to explore the roles that each discipline plays in the design of urban spaces. The frequent imbalance between disciplines is addressed both through the literature review and design method, as this landscape architecture thesis draws on architectural design as a tool for generating spaces which fall somewhere in between the two ideals of interior and exterior. The final design proposal is an alternative rebuild plan for the central business area to the south of London St, and also addresses the relationships between that site and the surrounding context, both urban and environmental. The aim of this design is to create a series of interconnected spaces which have a strong relationship to the surrounding harbour setting, and also to facilitate development of the pedestrian spaces throughout the block and encouraging the development of activity at the street level, through the interface between buildings and landscape.</p>
