In this article, we will provide a brief overview of the presentation by Violetta Volk, BIM manager at Severin saudi arabia phone number Development, at the BIM breakfast event, during which she spoke in detail about the list of data required to maintain a construction model, as well as the process of its creation using the company's projects as an example.
Severin Development is often involved in construction projects as a technical customer, and the topic of construction models is directly related to this role.
"At the beginning of the project, the main participants are the customer and the designer, and contractual obligations are formed between them. Only after this does the technical customer step in, and we can no longer influence the initial data that the general designer will transfer to us. And these initial data, specifically BIM models and the requirements that are specified at the stage of concluding the contract, are very important to us for creating construction models," this is how Violetta Volk described the problem that the company is facing.
In the list of data required to create a construction model, the expert highlighted a project model in an editable format, such as RVT or IFC. The availability of data allows solving many problems, such as uploading and processing work volumes and closing acts in the form of KS-2 at the end of the month.
The BIM manager also noted that the schedule of works and the contract estimate are important for maintaining the construction model, which allows you to link elements to the schedule, specify their cost and check compliance with design solutions. This helps to predict delays from the schedule.
The process of creating a construction model
At Severin Development this process is structured as follows.
The design model is taken as a basis, which is loaded into the main solution for information modeling (note: Revit). Then the elements are copied into the construction model, and after that the elements are fixed and the model is cut into sections. Why is the original design model not used? Because the model is constantly edited and updated, and if you take it as a basis for creating a construction model, the information and geometry of the elements will become irrelevant.
Once the model has been cut into sections, it is transferred to BIM model checking software (note: Navisworks), where construction control engineers fill in all the necessary information in the consolidated model regarding the construction stage: data on the element’s execution on site, acceptance dates, type of work and a link to the comment.
