The site of the mixed use complex is located in the Northern administrative district of Moscow in the Begovaya region, on the territory of the Second Watch Factory “Slava”. The terrain of the 1st Yamskogo Polya street is flat, going upwards to the existing development, the drop is about 3.5 m. Building’s target use – a mixed use complex with apartments, shops, cafes, offices, consumer services, underground parking. The complex consists of 6 apartment sections: 4 sections are connected in a complex U-shaped form with a variable number of floors (8-10-8-15 floors), 2 separate sections 16 and 17 floors high with an underground parking.

INFORMATION MODELLING TECHNOLOGY APPLICATION

Information modeling technology (BIM) was used for documentation development from the Concept stage to the Working Documentation stage.

- architectural and structural solutions, MEP – Autodesk Revit; 
- GC, pumping station – Autodesk Civil 3d;
- Model verification and coordination – Autodesk Navisworks, BIMCollab Zoom. 

The modeling and coordination process was conducted according to the Customer's information requirements (EIR). To coordinate the technology of unique elements modeling and requirements deviations registration, a project implementation plan (BEP) was formed and approved with the Customer.

Documentation for the sections was issued from information models. 

A classifier of constrcution elements was used to automatically extract the work volume list from information models. Each element of the model was assigned with a code corresponding to work. Based on the structured elements, the Quantification book was automatically filled in, which was later used for the General Contractor's tender.

IMPLEMENTED ADVANTAGES OF SINGLE  INFORMATION MODEL

Top-quality work of a big team on a large project could only happen with application of a single data source for the whole project. All project participants always saw only up-to-date information due to shared data environment (SOD). These processes took place though BIM360: transfer of models from the contractor, coordination of models by the customer, as well as exchange of information and comments between all project participants. 

Preparation of a large number of models for the Customer was carried out by using an internal plug-in that batch uploaded models to RVT, NWC and IFC formats. Based on the modulling results, a video visualization was created to analyze the final product. 

The models were checked on a weekly basis. The verification was carried out in two stages: automatic and manual. Automatic verification uploads reports on internal requirements compliance and Customer information requirements, manual verification is necessary to make a decision: whether the model meets the Customer information requirements.

INTRODUCTION OF OWN DEVELOPMENTS

An internal plug-in was used to work with openings, it covered all the needs of the designers. The plug-in includes the following functionality: - openings placement. A module for openings placement, which allows to place an opening with a specified gap, based on the choice of an engineering system and design. - exchange of openings. A module for transferring openings to adjacent sections using the HUB model. - communication and matching of openings. A module with correspondence about each opening and indication of its status.

BIM-MODELS BREAKDOWN LEVEL 

Due to the high level of models breakdown during Architectural solutions development, starting from the Design documentation stage, the physical decoration of premises was modeled in all rooms, which allowed to obtain accurate amounts of finishing materials. The process of finishing creation took place through an internal plug-in, which allowed to create the finishing depending on base material, type of structure and certain room. In addition to the finishing creation, the plug-in allows to create a list of interior finishin and explication of floors according to GOST. In the modeling process, special families of furniture, plumbing fixtures and electrical equipment were used, which included service areas. These families participated in collision checks to check the layouts ergonomics.

Помимо выгрузки помещений и зон формат IFC использовался для объединения импостов и панелей в единый витраж. Для корректного экспорта формировались два файла с настройками:

LOSS FACTOR - percentage of unused areas from the total building (floor) area  - was monitored online throughout the entire design process. To determine this indicator, the following zones were modeled: General, Used, Shafts, Public areas, Technical premises, etc. Further, these zones were exported as 3D objects using the IFC format and were used to calculate the object technical and economic indices. 

In addition to unloading rooms and zones, the IFC format was used to combine imposts and panels into a single stained glass window. Two files with settings were generated for correct export: 

1-File with mapping of parameters to the Customer's tab;
2-File that specifies the mapping of Revit categories and IFC categories;

The features of Structural solutions development include application of Revit analytical model, which had a connection with calculation complex. 

During the Engineering Networks development, starting from the Design documentation stage, all networks were separated without spatial collisions. To test the solutions of engineering networks distribution in the parking, special families of parking spaces with service areas were used, as well as drive-through and loading zones were modeled separately. Network engineers could not locate their networks in the dimensions of those zones.

Since the facility has a lot of engineering systems, the Appereance Profiler function was used for internal meetings and meetings with the Customer, which allowed to create color differentiation of elements depending on the system.
