BIM Cases (ENG)

How we prevented the loss of information when transferring model in Revit between multydisciplinary engineers?

What was the problem?
When designing various objects in BIM, there is a need to arrange the joint work of specialists, who develop adjacent design disciplines, and obtain assignments from them. Along with this, there is a necessity in a coordination model for the Chief Project Engineer and the Customer, where all disciplines to be developed are summarised.

It is important for the specialists to work with the relevant information and data, moreover, an exchange process should be quick and convenient.  Therefore, a standard data exchange method using Revit functionality "eTransmit" wasn’t suitable for this purpose, as the working model needed closing before each operation.

In addition, the risk that other specialists could damage the working model should have been excluded. To reach this, it was necessary to prevent the specialists from interacting with the models they haven’t developed.

What was the solution?
Thus, a decision to create Share Model plugin was made.
This plugin creates a model for transferring an assignment in the corresponding area, so that other designers can use it for work. Hence, no one can do harm to the working model of the designer. 
The working model doesn’t need to be closed before the transferring the task model. When the model is created, synchronisation is carried out and the central file is revised.

Additional features have been added to optimise and audit the created model:

  • Sorting elements into correct worksets
  • Creation of an NWS file for automatic updating the project coordination model
  • Deletion Manager for selected sheets, views and lists. 
  •  Model cleaning

What was the solution result?
Thus, having developed Share Model plugin, we managed to improve the quality and frequency of the assignment transfer, increase the speed of work and exclude the risks of work with irrelevant information. 

The solution has made it possible to arrange the joint work and common data environment in accordance with standard ISO 19650.

Пример экономии времени и средств на реальном проекте:

Группа компаний ENECA разрабатывала 4 раздела жилого комплекса из 8 секций высотой 44 этажа и паркинга. 
Суммарно было 32 модели которые разрабатывали около 20 проектировщиков, а процесс передачи модели задания происходил дважды в неделю. Длительность проекта составляла 9 месяцев (36 недель).

В связи с большим размером рабочей модели, а также большим количеством ссылок на модели смежных специалистов, ручной процесс передачи занимал около 10 минут.

Учитывая, что при каждой передачи модели с помощью плагина экономится около 35% времени в сравнении с ручным способом, то мы можем посчитать сэкономленный бюджет проекта за счет автоматизации:

Обычная передача модели:
32(модели) * 2(передачи в неделю) * 0,167ч. (10 минут) * 36 (недель) * 100 евро / час = 38476,8 евро за весь проект

Передача модели плагином:
32(модели) * 2(передачи в неделю) * 0,167ч. (10 минут) * 36 (недель) * 100 евро / час *0,65% (35% экономит плагин) = 25009,92 евро

Сэкономленный бюджет: 
38476,8 - 25009,92 = 13466,88 евро
