The Irina Viner-Usmanova Rhythmic Gymnastics Center in Luzhniki won the BIM project. Sports facilities”of the first All-Russian competition of BIM technologies. Work on the project began in the first half of 2016, today the building frame has been erected, finishing work should start in the spring of 2018 - the speed of design and implementation is largely due to the fact that the authors used the OPEN BIM approach based on the use of open IFC file formats, which allows specialists working in various software systems to successfully and efficiently interact at all stages of modeling.
The sports complex is being built on the site of the famous clothing market in the northeastern part of the Luzhniki Stadium, includes an arena for competitions, training halls, a medical center, a hotel, administration offices, as well as office and utility rooms - all of this is collected under one roof in the volume of a simple parallelepiped, whose laconic form made it possible to optimally place all the necessary functions in a fairly compact area. However, the simplicity of stereometry is not readable by the eye, in any case, it is not read immediately - all attention is drawn by the roof covering it with a wave. Starting its run in the west, it topples over with a vertical wall in the east. The metallic coating of the surface with flakes, shimmering in the sun, enhances the dynamic effect.
The acceleration of the wave begins above the training halls, and its highest crest corresponds to the main arena with stands for 1250 seats, the heart of the building - here the main competitions and training sessions take place. The hall is 18 meters high "above the carpet", which is optimal for rhythmic gymnastics, and can be transformed for concerts and other public events.
The public areas are located in the southeastern part of the center: the main entrance and press entrance with a high lobby atrium, foyer and cloakroom are located here. The northern one is given to athletes: it has a separate entrance and a medical center and a hotel for 150 people are located on five floors. Functional zoning is emphasized by glazing: starting from the transparent from the southeastern facade, it “condenses”, the rhythm of the pylons becomes more frequent, then, in the northern part, to move to the minimum glazing on the facade of the hotel.
The project of the building, the undulating roof of which resembles a fluttering gymnastic ribbon and therefore perfectly suits its purpose, becoming, in fact, a giant volumetric symbol of the gymnastic center, was developed by the architects of TPO "Pride".
From sketch to project
According to the architects, the expressive image associated with the rapid movement emerged immediately. But it's one thing to outline an image with a stroke of a pen, and quite another to bring an idea associated with a bold curvilinear shape to implementation, and in a fairly short time.
TPO Pride has been working with ARCHICAD since the company was founded - it was decided to stop at this program, since it was developed as a specialized professional tool for the work of architects. The choice did not disappoint: the developers are constantly improving the tool, greatly simplifying work processes, adapting it to the actual needs of designers. The architects of TPO "Pride" consider the possibility of teamwork to be especially important - there are 65 employees in the bureau, and ARCHICAD Teamwork helps to coordinate their teamwork. So the question of what software the project will be executed on was not: the search for an idea and its discussion with the customer was accompanied by the creation of a sketch model in ARCHICAD, although the visualization of individual elements for the presentation was performed in 3ds Max.
Three-dimensional models created in ARCHICAD starting from the concept stage allowed choosing acceptable options for architectural solutions. In particular, the authors have developed several options for roof-bearing structures: from wooden rafters to metal frames. The latter was chosen to satisfy both aesthetic and economic requirements. The developed concept of TPO "Pride" was presented to the customer in a mobile application
BIMx® GRAPHISOFT.
Using BIMx® He significantly helped in making a decision on the project - his CEO Elena Myznikova is sure: “At the final presentation of the concept, we provided the customer with the opportunity not only to see the future building from the outside and inside, but also to“walk”through it using the application loaded on the customer's tablets. Consider in detail the facades, the interconnection of the premises, analyze the materials. Thanks to the carefully designed model and its presentation, the customer believed that everything that was drawn will be built. One of the great benefits of the BIMx app® - it does not seriously load "hardware" and can be downloaded to any smartphone and tablet. The application became a serious help in communicating with the customer and later, in the work on the stage "P", especially since it allows simultaneous navigation through 2D documentation and 3D models of buildings."
OPEN BIM
The architects of TPO Pride believe that Building Information Modeling (BIM) technologies should be actively used in modern design and construction, and have been working with BIM design technologies for four years. However, it was in the project of the Irina Viner Center that they first decided to apply the OPEN BIM approach to organize joint work with related specialists working with other software.
According to Nikolay Gordyushin, the author and the chief executive officer of the project, the decision was logical: “When the work began, receiving drawings from subcontractors, we realized that they also work with BIM solutions. Then we decided to try "assembling" a full-fledged model using the open IFC format. For the architect, from whom everything begins and on which everything ends, on which, in fact, the whole project rests, OPEN BIM is the ability to quickly respond to changes in the project proposed by specialists from other fields, and for sub-designers - the opportunity to work in those programs to which they are accustomed and which correspond to the requirements of the profession."
As you know, the most difficult thing in a job is to start it. So in the case of the design of the Center for Rhythmic Gymnastics, most of the time was spent on debugging the system of collaboration.
At the beginning of the work, the architects of TPO "Pride" created a BIM model of the future object in ARCHICAD, then the data of the base model, filtered depending on the needs of subcontractors, was transmitted to them in an open IFC format; and in the same format, the base model, enriched with the developments of subcontractors, was returned back to the bureau for incorporation into the base model. The used IFC protocol saves not only the entire geometric description in 3D, but also its location and relationships, as well as all the properties, or parameters, of each object, so that it can act as a universal tool for saving and transferring information from different programs for BIM design. At the stage of creating a basic model, which will then have to be worked by outside specialists, it is important to correctly classify all objects and understand that the traditional model with which architects work may not be enough, the authors clarify.
In neutral territory
Engineering sections were developed using Revit design software with plug-ins that allow you to calculate specifications. The architects of TPO "Pride" have successfully coped with the functions of BIM managers, collecting all the information into a model and passing it further along the chain.
One of the main participants in the “assembly” process, the chief architect of the bureau Vitaly Krestyanchik, positively assesses the possibilities of the OPEN BIM approach: “We got a lot of positive results from the experience gained. Despite the fact that the process of debugging the data transfer took quite a long time, as a result, we gained much more time due to the fact that thanks to the OPEN BIM approach we were able to instantly track inconsistencies in the project - the so-called collisions - and quickly make changes during work. Initially, it was necessary to understand what data is needed for each of the sections for the work of subcontractors - and this is perhaps one of the longest processes."
The BIM model in 3D immediately proved the correctness of the decision - in the very first model with the engineering part of the project, the collision check on the engineering networks revealed about 1800 inconsistencies. Of course, traditional 2D drawings also involve finding errors, but this takes more time and is not always possible to identify them completely. And, although the errors were insignificant: somewhere the wall was not moved or the marks were not observed - in the future, multiplying in progression, they could lead to unforeseen consequences. When designing the Gymnastics Center, the search for errors was carried out in a semi-automatic mode, based on a careful examination of the model to identify unnecessary intersections.
In the new version of ARCHICAD 21, developed by GRAPHISOFT, the search and detection of collisions has been improved - it allows you to instantly search for inconsistencies between two groups of user-defined elements, signaling problems and pointing out "sore spots".
According to the architects of TPO "Pride", one of the main guarantees of successful design is early agreements between designers and architects on working conditions, the creation of rules for joint work, since it takes time to link complex BIM models.
The convenience of open design can be assessed, in particular, by the following example: the designers of the Kazan Giproniiaviaprom company, who worked with different sections of the structure, monolithic reinforced concrete load-bearing structures were developed in Revit, and the metal structures of the floors - in Tekla, interacting with each other - within the same company - through BIM-model, created in ARCHICAD by architects TPO "Pride". As in the case of utility networks, the IFC format became the assembling point: with its help, the exchange between software platforms and sections of the project was carried out.
Architectural flight
The most expressive element of the building, the roof, has become one of the most difficult for architectural design. According to the plan, the visual effect of the iridescent scales of the wave was to be formed by aluminum cassettes of decorative cladding, fixed on a folded base.
Therefore, in addition to the search for the geometry of the expressive silhouette of the wave, commensurate with the volume of the building and its surroundings, it was necessary to find the appropriate materials that would meet the assigned tasks: they would bend at the right angle and would tightly join each other, since the gutters run along the roof. And also a manufacturer who could fulfill them. Another parameter was the repeatability, that is, the typification of various elements: trusses, cassettes, folds, since the variety of modules significantly affects the economics of the project.
The Rhinoceros / Grasshopper program was used to create a parametric model of the roof structure that allows for quick selection according to the specified characteristics. The newly developed dynamic link to ARCHICAD through the Grasshopper-ARCHICAD Live Connection add-on made it possible to make full-fledged BIM elements for use in the architect's familiar environment, the resulting three-dimensional figures modeled in this program. Bidirectional data exchange between ARCHICAD and Rhino / Grasshopper made it possible to transfer complex building geometry into a format familiar to architects and perform the most complex calculations.
The future of information modeling
In the design process, the use of BIM technologies made it possible to reduce the time of work and avoid costly alterations at the construction site, OPEN BIM helped to optimize the interaction between subcontractors and the management of the project as a whole.
Even today, during construction, additional information is added to the BIM model, adjusting materials and elements related to finishing work. The BIM model will be in demand after the completion of all work. For example, it can be provided to the building maintenance service, thus facilitating its work with communications.
According to the architects of TPO Pride, the development of the OPEN BIM approach and the use of the IFC format should go hand in hand with the introduction of a unified BIM design standard at the state level, which would regulate the exchange of information between various platforms and companies in the design, construction and operation of buildings - and prepare all participants for the introduction in 2019 of the use of BIM technologies as a prerequisite for objects of state order. ***
