Adaptation of the graphic program for constructing of a specific class of technical means, being the specialty of the design and construction office, is the basic challenge of the market economy. This office that prepares the offer and then the competitive construction of the technical means in the shortest possible time as a result obtains the order. This effect is enabled by graphic software applications.

This article describes some of the safety considerations for the design and construction of micro/nano facilities and applicable building code provisions. The two key elements required for safe operation in micro and nanotechnology facilities are: (1) engineered features incorporated into building construction, and (2) administrative features that deal with how people work within the facility.

The article deals with some interesting engineering solutions implemented in the process of installation of arch span structures of the channel part of the bridge crossing the Volga river in Nizhny Novgorod, due to the design features of the arch span structures and local conditions: technology of assembling arches on the coastal slipway; construction of the slipway for Assembly and tightening of the arch trusses of the arch; technology lateral shifting of the arches on the piers on carriage; design piers of the carriages and pusher device; technology of loading and transportation of arches on floating supports; design of floating supports, their adjustment, strengthening of used barges; snap-in for positioning floating supports; erection strengthening arched spans with temporary stands and pendants; technology of lifting and installation of arches in the design position; used equipment and floating means; a way of immersing the tubular piles piers and methods to confirm their load-carrying ability; necessary coordination with regulatory organizations. The engineering novelty of the above technical solutions in the method of installation of arched superstructures with flexible tightening and cable-stayed suspensions – a design that was not initially adapted to surfacing installation. The author presents drawings and photographs of the most typical auxiliary structures and technological processes that took place during the construction of arch span structures of the bridge. This material can serve as an analogue in the design and construction of such out-of-class bridges across large navigable rivers.

The Design and construction of metal bridges is the most reasonable from the structural and technological point of view, as well as from the standpoint of the implementation of non-standard engineering and spatial solutions. The weak point most often in this case is the efficiency of construction. To improve economic efficiency, it is recommended to use metal structures, the most loaded elements of the beams in which should be made of high-strength steels, and all other conventional rolled steel. Spans of a continuous plate should be designed in such a way that the spans moments are equal. The authors propose to assign the values of spans in accordance with their effective ratio and design the span structure of the three types of standard blocks.

High-rise buildings are unique construction objects, in the design and construction of which special rules and regulations apply. The purpose of the work is, through an analysis of the literature and technical documentation, to present the main features of the construction of high-rise buildings. Based on the results of the study, differences in the concept of "high-rise building" in different countries were identified, specific problems encountered in high-rise construction were described, and design features of high-rise buildings were described. Special attention is paid to additional difficulties arising in the construction of high-rise buildings, due to the specificity of loads, construction technology, operation of high-rise buildings, and other reasons.

The hotel industry is beginning to implement green design and construction practices, saving energy, water, and resources and thus helping to preserve the environment. In addition, green building practices also can provide healthy and comfortable indoor environments to hotel occupants including guests and employees. However, there is the potential for conflict between green building practices and hotel guests' satisfaction and comfort, as the conservation of resources could detract from the quality of a guest's visitor experience. This study adopted a case study approach to identify and analyze green design and construction practices that create a green and luxurious environment without damaging the hotels' financial position. An in-depth literature review was conducted to identify green design and construction practices, design features of premium hotels, and major design conflicts between the twin goals of green building and a luxurious hotel environment. Two LEED platinum hotels (the Proximity Hotel and the Bardessono Hotel, both in the United States) were selected and data collected on their green design and construction practices, luxurious design features, and operation and maintenance practices from multiple sources, including the owner, designer, contractor, engineer, and LEED consultant. From the perspective of the entire lifecycle of the building, this data was analyzed to identify green design and construction practices that not only provide a green, luxurious environment but also enhance the hotels' financial strength.
