BIM management

In addition to the work directly related to the design, there are many tasks for organizing the BIM process: deploying a common data environment, writing regulations.

Also, the work of a BIM manager includes training employees and assistance in conducting a pilot project: developing a library of families, setting up a template, etc. And assembly and coordination of summary models in Navisworks, Solibri allows for intelligent checks.⠀

An important point is the automation of routine processes using macros, for example, filling in parameters, compiling complex specifications, balancing elements of engineering systems.⠀

Below are elements from the work of our BIM managers.

  • Shared Common Data Environment (CDE), Deploying a shared data environment on a customer’s server for collaboration in a Revit environment. Providing access to Revit-Server for all project participants.
  • Shared Common Data Environment on BIM360 cloud service
  • Writing regulations for working in the CDE, creating and describing the folder structure, assigning access rights to folders and files
  • Writing documents regulating the implementation of a BIM project, training employees to write and compile such documents. Conducting an audit of the company, identifying the general principles of project management, information exchange within the company, determining organizational roles and functions, project departments and groups. Based on the audit, a detailed BIM Execution Plan (BEP) is drawn up, on the basis of which the project will be carried out. This document sets out the rules for the common data environment; access rights; rules for naming project files; basic requirements for the content of the information model, the structure of its division; model coordination requirements; interaction of project participants; ways of issuing tasks; procedure for issuing documentation; naming rules for information model content; level of detail requirements.
  • Training of company employees in the basics of designing in Revit, Navisworks software. Full consulting of employees throughout the tight project, by recording training videos on issues of interest, conducting consultations
  • Assistance in conducting a pilot project. Assistance in developing families and customizing families for a company template, developing a library of families
  • Training employees to create families of varying complexity: parameterization, nested families, use of selection tables, etc.
  • Pilot project coordination. Assembly of summary models in Navisworks, Solibri. Creation of reports on intersections in the form of tables, viewpoints. Unloading collisions through BCF Manager with the ability to further work with the report directly in Revit.
  • Conducting smart checks in Solibri, unloading volumes from the summary model.
  • Automate routine tasks with Dynamo and macros for Revit.

Example 1: ISO HVAC specification. The macro transfers parameters from elements of different categories to general parameters, whereby a multi-category specification is created. It is possible to refine the Autodesk macro for any purpose of the customer, as well as for any template and for any Shared Parameter Files.

Example 2. Preparing a model for examination. The script fills in the parameters necessary for the examination in all elements of the model according to the specified algorithms.

Example 3. Automatic filling of flow rates in air distributors from the table of air exchanges. The script determines in which room the diffuser is located, the number of supply and exhaust diffusers, takes the air exchange value from the table and distributes it to all diffusers in the given room.

BIM modeling

The functionality of revit allows you to create models of architectural, structural and MEP sections. It is possible both to develop a project from scratch (including joint several sections) and to raise models according to existing 2d documentation. ⠀
BIM models form the basis of document management, coordination and modeling throughout the life cycle of a project.⠀


To create projects, families are used – blocks, parametric 3d models. Creating their base is an important stage of development. The main feature of the families is the change of geometric information and other parameters depending on the standard sizes, formulas or selection tables. All this allows us to get the “block” we need and automatically enter information about it in the statements. ⠀

Конкурс “Ресурс переферии”

Competitive design area: part of the residential area of the Krasnogvardeisky district of St. Petersburg and the adjacent coastal area of the Okhta River.

The total area of the design area is about 602 hectares.

The purpose of the competition is to receive proposals for improving the quality of the environment in residential areas built according to standard projects in the Soviet period using the natural, historical, cultural, social and territorial resources of the territory.

The participants will have to create a concept of a system of public spaces, a communication framework that combines intra-microdistrict residential spaces with objects of attraction for pedestrian and bicycle routes, including landscaping, lighting, proposals for the placement and design of temporary structures and small architectural forms.

The competition program includes the results of a sociological survey of residents of the area, conducted jointly with the Quality of Life Laboratory of the Institute of Design and Urbanism of ITMO University.

In this competition, we considered the creation of a concept of public space in the Zhernovka estate and within the selected microdistrict, based on information about the movements and preferences of residents, plans for the improvement of the area, and requirements for connecting districts with each other.

We have developed a concept for the renovation of existing facilities on the projected site for the use of active population groups, as well as the Manor was not fundamentally affected, but its surroundings were made in the style corresponding to this object. On the site there are power transmission lines for various types of activities in the immediate vicinity of them, which is not allowed according to SanPiN standards, therefore this part of the site was given over to parking spaces for vehicles. The goal of the project is not just to connect individual sections within the boundaries of the design, but to create a diverse center of attraction, which includes sports, cultural, and leisure functions.

The project of public space in the area of the Zhernovka estate consists of several zones, the closest to the estate corresponds to the style, to the south of the estate there are Soviet-era industrial facilities located in the protected area of the estate. The project describes the reformation of industrial buildings in order to create a multifunctional art complex, including areas for activities, recreation and placement of public art.

The art complex is followed by a sports area that meets public needs. It includes areas for skateboarding, ball games and an area for strength training and crossfit.

The zones are united by an alley separated from it by a cycle path and a multi-level embankment designed from environmentally friendly materials designed throughout the public space. The project of the embankment reveals the potential of the landscape and fits into the project of strengthening and beautification of the Okhta coast.

In the presence of large territories, the complex can become a place of attraction not only for the adjacent residential areas, but also to attract certain groups of the population throughout the city. Also, within the framework of the design, there is a robin park with an established image, for this reason it is not affected in terms of large-scale changes, but is supplemented by bicycle and pedestrian paths to create a single walking frame in which the robin will play the role of a walking and leisure space. Also adjacent to the design site is Sosnovka Park, which, in turn, is also in demand. In order to connect the system of separate spaces for the attraction of the population, an alley along the project of Entuziastov and Kosygin is proposed in the project. It will become both a link for the parks and an efficient way to move different populations.

According to the intra-quarter: it is proposed to develop the sports part in the improvement of the area. At the moment, educational institutions with private territory are predominant. all newly designed sites are proposed to be built inside the block on free plots as an interconnected group of objects, possibly giving the adjacent part of the transport routes for a pedestrian zone with the possibility of special vehicles. Large areas of the territory along the perimeter of the quarter should be adapted for parking lots.

In the considered quarter, as in many quarters of the site, there are green areas with undeveloped paths and sites, in the project we combined them with a single concept, forming pedestrian and bicycle alleys within the area and connecting sites for different purposes with each other. The creation of intra-quarter bike paths allows you to get out alleys-bicycle paths that connect the areas with each other and with large public spaces.

With a staged organization of work, the first stage should be to build large connecting routes, later moving on to smaller routes and public spaces.

Engineers VS covid-19

At the first stage of the team competition in the “Design and Modeling” direction, the participants had to develop a BIM model of the SPbPU research building in the Autodesk Revit system.

In the second stage, participants used CFD modeling in the Autodesk CFD system to re-arrange the classroom or office space to reduce the risk of infection spreading among students, students and employees.

In connection with recent events in the world, the issue of protecting people from various infectious diseases is particularly acute. There is a need to design new buildings and modernize existing ones with a new approach. The main objective of our work is to simulate the air flow in an existing room in such a way as to minimize the risk of infection spreading. It is also necessary to complete this task by spending the minimum possible amount of money. To find the optimal solution, the following goals were set:

Initially, we must understand what criteria can be used to analyze the premises in terms of protection against the spread of viral diseases. According to the recommendations of the World Health Organization, people should stay at least a meter apart in public places. Rospotrebnadzor imposes even more stringent conditions for people to stay indoors: it is necessary to maintain a distance of 1.5 meters. Thus, the first requirement for the investigated premises is the distance between employees. This is where the direct documented instructions about the layout end. To determine the second criterion, we turned to the studies of doctors of viral infections. Sources of infection can be transmitted by airborne droplets. And an infection like coronavirus is heavier than air, therefore, you need to block the direct path between people in the room. Based on a software package that can simulate the movement of air flows from supply ventilation to exhaust, we have formed the second criterion. Its essence lies in the arrangement of workplaces in such a way that the trajectory of air movement does not cross 2 people at once. By fulfilling this requirement, we will ensure that a person does not infect colleagues.

Original model

With the initial arrangement of furniture in a given room, a distance of 1.5 meters between employees was observed. The result of the calculations, in which the sets of particle traces correspond to the places of placement of people (agents # 1-10), indicate that the initial placement of people in a given room is not safe in the presence of the possibility of spreading infection.

In 8 out of 10 cases, air flows have a trajectory passing through several agents at once, which is unacceptable in terms of the generated requirements and safety criteria.

Protective screens and ventilation

The result of the calculations, in which the sets of particle traces correspond to the places of placement of people (agents # 1-10), shows the effectiveness of installing protective screens and two vents, as well as partial rearrangement. The idea of this option is the symmetry of the arrangement of ventilation and holes along the axis of the cabinets

In all ten sets of traces, the airflow passing through any agent did not fall with its trajectory to the locations of other agents. Thus, the likelihood of spreading infection is reduced to a minimum. The distance between people meets the requirements of Rospotrebnadzor and is at least 1.5 meters. The absence of intersection of the air flow trajectories of several agents at once is given in Table 3 below.

Stage 3

In the final part of the competition, it was necessary to simulate the movement of people in various scenarios using the AnyLogic simulation system and propose solutions to improve the level of security. Participants offered their solutions based on the recommendations of Rospotrebnadzor, WHO and the results of their own research

In 2020, the COVID-19 pandemic hit, leaving a mark on every area of ​​people’s lives. Education was no exception: schoolchildren stopped attending schools because of the likelihood of getting sick. In the near future, educational institutions will reopen, which means that it is necessary to develop models of people’s behavior in the current conditions. And do it in such a way as to exclude or at least minimize the likelihood of the spread of infection. The main task of our work is to conduct simulation modeling in the AnyLogic software system. The purpose of this simulation is to generate solutions to reduce the concentration of people in the areas under consideration in order to increase the organization’s resilience to the spread of COVID-19. We have received 4 scenarios for the development of events, for which it is necessary to build a simulation model: entrance, recess, canteen and evacuation. To solve the problem, you must perform the following steps:

  • recreate the model in the AnyLogic program according to all the conditions specified in the terms of reference;
  • assess the level of concentration of people in the areas under consideration;
  • in the presence of an increased concentration of people, develop security measures to achieve the norm;

School entrance

The number of students arriving cannot be distributed without the formation of long lines and crowds. Moreover, any targeted measures also failed to bring results. Therefore, it was decided to delimit the arrival of students in half with a shift by an hour. Our next step was to simulate the arrival of the 1st shift of students. The longest place to stay at the entrance is the wardrobe. According to the terms of reference, students must be in the cloakroom for 5 minutes. Therefore, to optimize the influx of students, 75 people were allocated who arrive at the cloakroom in the first place. It is assumed that these are students of the 11th grade.

After 3 minutes 20 seconds, the rest of the students begin to arrive at a rate of 13.5 students per minute. Measures were also introduced to delimit the flow in the school yard to minimize contact between students. To prevent people from crowding in front of the cloakroom, a waiting area was introduced in which students stay when the cloakroom is full

Summing up, we can conclude that the best option would be to divide the students into 2 shifts with an hour difference in arrival time. This measure will minimize the risk of infection transmission. If you try to organize the entrance of all students within one hour, then the risk of getting infected increases several times. The optimal number of arriving people is 700.

Change at school

The next step was to introduce restrictions and conditions into the plan according to the scenario. This explanatory note was made for the task “Change”. The following actions are envisaged to reduce the concentration of people:

  • flow demarcation
  • creation of waiting areas
  • shift in schedule
  • delimitation of exit time from classes

The next point in working out the task is to set the conditions prescribed in the terms of reference and run the model. Students must exit the classrooms within the first 3 minutes and head to the waiting area before the next lesson. The total change time is 15 minutes. In the last 3 minutes, students must proceed to their classrooms. The following are drawings of the simulation area:

We see that there is a huge excess of the permissible concentration of people in the corridors. Also, the allotted time is not enough for people to have a good rest and move to the right office.

Summing up, we can conclude that this option of moving students around the classroom puts them at risk of getting infected. The essence of the problem lies in the movement of people between floors, sometimes it is necessary to pass more than 2 spans. To optimize the work of the school, it is necessary to reduce the vertical movement of schoolchildren to a minimum, and, if possible, conduct all classes for grade 1 on one, maximum two floors. Thus, using simulation modeling in the AnyLogic software system, it was possible to identify the impossibility of solving the problem of reducing the concentration of people in the areas under consideration in order to increase the organization’s resilience to the spread of COVID-19
