The paper presents the results of research in the field of the use of innovative technologies in the design of buildings. The modern technologies of information modeling, in particular, BIM, which makes it possible to represent the building not only in three-dimensional space, but also allows designing it in the dynamic system « design - construction – operation » are considered. The experience of using BIM technologies is based on identifying errors at the initial design stage and the possibility of their elimination at the same stage. The development of mechanisms for detecting design errors and defects formed the basis of the task set in the work. A model for signaling about the detection of defects has been developed, and the problem of stochastic modeling of the qualitative parameters of the designed object has been solved.

In the past two decades, building information modeling (BIM) has been widely adopted by architectural, engineering, and construction firms. Its technology is based on the integration and coordination of different disciplines and professions. It involves creating three-dimensional models containing data that can be organized and manipulated to serve design, construction, and operational phases. This raises the debate over how the existence of a platform that enables urban planners and decision makers of different disciplines is so crucial. Several research studies have recently been done to integrate BIM with geographic information systems (GIS) for numerous purposes, as illustrated by several case studies. This chapter comparatively analyzes different cases, given general acknowledgment of each. Problems and potentials of the existence of such integration will be defined, in order to estimate the need for such a platform. Finally, a model of integration between different disciplines was illustrated as a motivation for further studies in the future concerning this topic.

In the context of the Brazilian electrical sector, there are no references regarding the application of BIM (Building Information Modeling) and GIS (Geographic Information System) in construction and maintenance of Electric Power Substations projects. Thus, this work proposes the integration of these technologies, since preview experiences in other engineering fields have shown promising advances that could be useful for the management and maintenance of the electrical power market. By associating these technologies, an accurate mapping of the information related to the assets, arrangements, cabling, bus, electrical components, etc, is obtained. Moreover, for this integration works, it is required to design a three-dimensional geometric database of the electric power substation active com-ponents. Inserting one of the database models into a particular point of the project shall bring constructive, operational, and maintenance information. Thus, by combining BIM and GIS in the modeled families, it is possible to obtain more consistent information during the construction phase. This will provide advantages in decision making, providing resources within the corporate communication, and a better understanding of the environment related to an electrical energy substation. Additionally, the location conditions and the surroundings of the substation would be more precise and pertinent, since the components of the substation will become Geo-referenced. The association between these two platforms allows a more intuitive overview of the project, making them adherent to the planning, design, construction, operation, preventive, and corrective maintenance. So, when applying these tools together the company will obtain results almost immediately since all managing features will be accessed through only one integrated information database. This proposal presents the first results of the integration of BIM and GIS, in the context of a Brazilian electric company - Furnas S/A. Results of the implementation of the solution in the context of Substations of the Company are discussed and show the availability of reducing construction costs, alteration planning, logistics, on-demand of the necessary maintenance, prevention of possible accidents, and possibility of updating information in real-time.

AbstractIn the past, knowledge in the fields of Architecture, Engineering and Construction (AEC) industries mainly come from experiences and are documented in hard copies or specific electronic databases. In order to make use of this knowledge, a lot of studies have focused on retrieving and storing this knowledge in a systematic and accessible way. The Building Information Modeling (BIM) technology proves to be a valuable media in extracting data because it provides physical and functional digital models for all the facilities within the life-cycle of the project. Therefore, the combination of the knowledge science with BIM shows great potential in constructing the knowledge map in the field of the AEC industry. Based on literature reviews, this article summarizes the latest achievements in the fields of knowledge science and BIM, in the aspects of (1) knowledge description, (2) knowledge discovery, (3) knowledge storage and management, (4) knowledge inference and (5) knowledge application, to show the state-of-arts and suggests the future directions in the application of knowledge science and BIM technology in the fields of AEC industries. The review indicates that BIM is capable of providing information for knowledge extraction and discovery, by adopting semantic network, knowledge graph and some other related methods. It also illustrates that the knowledge is helpful in the design, construction, operation and maintenance periods of the AEC industry, but now it is only at the beginning stage.

The Spanish construction industry has been subject to EU Directive 2014/24/UE. This directive allows member states to encourage, specify and even require the use of Building Information Modeling (BIM) in construction projects financed by EU public funds as of 2016. The QBIMInvest Project (supported by the Universidad Europea de Madrid) has conducted a survey, which is the subject of this article, on the implementation of Building Information Modeling in the Spanish AEC industry. This research uses 548 responses from a sample of Spanish AEC professionals to demonstrate that currently BIM tools are only being used in the design stage of residential buildings. There are few cases of them being applied in the construction, operation and maintenance stages or in other project types. On the other hand, professionals think that they will need at least 3 to 5 years to finish implementing BIM in projects.ResumenLa directiva UE 2014/24 invita a los Estados miembros a que fomenten, especifiquen y requieran el uso de Building Information Modeling (BIM) en los proyectos de construcción financiados con fondos públicos de la UE a partir de 2016.

<div> <div> <div> <p>“Peptoids” was proposed, over decades ago, as a term describing analogs of peptides that exhibit better physicochemical and pharmacokinetic properties than peptides. Oligo-(N-substituted glycines) (oligo-NSG) was previously proposed as a peptoid due to its high proteolytic resistance and membrane permeability. However, oligo-NSG is conformationally flexible and is difficult to achieve a defined shape in water. This conformational flexibility is severely limiting biological application of oligo-NSG. Here, we propose oligo-(N-substituted alanines) (oligo-NSA) as a new peptoid that forms a defined shape in water. A synthetic method established in this study enabled the first isolation and conformational study of optically pure oligo-NSA. Computational simulations, crystallographic studies and spectroscopic analysis demonstrated the well-defined extended shape of oligo-NSA realized by backbone steric effects. The new class of peptoid achieves the constrained conformation without any assistance of N-substituents and serves as an ideal scaffold for displaying functional groups in well-defined three-dimensional space, which leads to effective biomolecular recognition. </p> </div> </div> </div>
