Stages of implementation of information modeling technology in the design organization

The development of modern information technologies leads not only to an increase in the computing power of modern computers and the improvement of the capabilities of specialized software in the field of construction design, but also the need to develop approaches for the implementation of the proposed technologies at the stage of construction design.


Introduction
When developing a plan for a step-by-step plan for the implementation of information technology design, first of all, it is necessary to take into account the goals of implementing BIM in the organization, which will allow it to adequately assess the need to switch to design using BIM technology. Such a transition is justified if the customer needs an information model or the BIM format is specified in the design specification.
At present, many engineering firms have faced the fact that in the specifications in addition to the usual composition of design and working documents indicate the need for a BIM-model, so the transition to information modeling is becoming a critical aspect of ensuring competitiveness in the current market design and construction.
At the next stage, in addition to providing the design process with modern hardware and software, there is a need to understand how to create a digital model of a building, you need to know how to implement this new technology, taking into account the specifics of designing objects saturated with engineering equipment and systems. For example, in the case of designing curved designs in industrial and civil buildings, as a rule it expensive items, the cost of failure in the design of which is very high, three-dimensional the display BIM allows you to simulate different options coupling elements of designs with engineering systems. Visualization of three-dimensional model allows you to make these systems viable, that is, to design them in a way, to avoid possible collisions between structures and utilities in the construction and subsequent operation of the facilities.
An important task at the planning stage of BIM implementation is the need to implement joint work between sections of the project. This is one of the most difficult tasks in the implementation of BIM, since it is not easy to establish the exchange of data and combine them into a single whole, however, new technologies for converting and exchanging data make it possible to optimize this process and minimize the number of common design errors -the same intersections of communication with the supporting frame and between itself, identifying and eliminating them at the design stage. In addition, it becomes possible to automate the calculation of the volume of materials. After the implementation of the model any object it is possible to calculate the volume area, the number of structures in the project and so on all the parameters, which may be necessary, which is an invaluable aid to the designer of the automatic compilation of estimates and statements.
Thus, the formation of the plan and the gradual introduction of information technology BIM design is becoming one of the main objectives of the project organization.
In the presented work, an attempt is made to form an approximate structure of a BIM implementation plan.

It should be noted that the implementation and implementation of the plan should be carried out by specialists with the necessary experience and qualifications.

References to regulatory documents
The development plan for the implementation of BIM should be based on the used AIs are following s standard s and guidelines governing information modeling:

Basic terms and definitions
• 2D -Object Model: Displays the geometry and position of objects on the plane (X and Y coordinates).
• 3D -a three-dimensional model of the object, created using the appropriate software products. • 4D -model includes previous models, as well as a construction and installation process control system that allows you to control the construction process of an object, for example, the process of work in accordance with the network schedule, and also allows you to make operational changes to it if necessary. • 5D -model -in addition to the 4D model, it allows you to manage the cost of construction and installation work, components and materials, thereby preventing unjustified overspending of financial and material resources during the construction of an object.
• 6D -concept for monitoring energy consumption throughout the construction and life cycle of a building to take optimal measures to reduce the building's energy consumption.
• 7D -ensures effective property management, including security monitoring, current and planned repairs and reconstruction.
• BIM-building information model: a digital representation of the physical and functional properties of a construction object, at all stages of its life -design, construction, operation, renovation and liquidation, serving as a source of collective knowledge for various specialists in the field of design, operation, modernization and etc.. • Building Information Modeling -the process of collectively creating and managing information about a building object, which forms the basis for decision-making throughout its life cycle.
• BIM project or information modeling project is a construction project developed using BIM technologies.
• Collision detection -the process of detecting design errors, according to standardized or other parameters, for example, permissible distances between elements, geometric intersections, logical relationships between elements, and so on. • Exchange of information -structured collection and reporting of information that meets the format requirements and the level of confidence per m of pre-defined stages of the project.
• IFC is a universal format for standard data exchange between BIM applications.

Step-by-step BIM design technology implementation plan STEP 1. Transition from computer-aided design to BIM information design. (Laying the groundwork for BIM adoption.)

Customer's enterprise audit
At the first stage, the audit of the enterprise: • Conducting interviews with managers to determine the goals and objectives of implementing BIM technology (in person or remotely).
• Interviews with key professionals to understand existing design and collaboration technologies and identify their strengths and weaknesses (in person or remotely).
• Collecting information about the characteristics of the work and the maturity of BIMtechnologies in the client's company.
• Analysis: the format of interaction between departments, standards for the design of materials for project documentation, the specifics of designed objects, sources of information for the BIM model. • Object selection for the pilot project of the most typical 's customer objects.
• Preparation of detail of description I services for the implementation of BIM technologies, including 3D, 4D, 5D, 6D and 7D.
The detailed terms of reference gives the contractor and the customer the same understanding of the scope of work that is intended for the implementation of the implementation project.
Based on the results of the audit, the terms of reference for the implementation and transition to BIM technology are developed and approved.
