BIM Engineer


Ana Maria Walter de Rossi is a Civil Engineer and Bachelor of Science in BIM expert in managing and controlling works on site, specially infrastructure projects in Latin America and Europe with 30 years of experience. Currently, as BIM Technician in the company Hanley Pepper, she is developing 3D structural models using the BIM methodology.

When I finish my degree many years ago, CAD didn´t exist and digitalization, specially in the AEC sector, was in the firstly stages. The upskilling is the key of the professional development, so I had to acquire new knowledge in order to use new software.

At the moment, I am producing 3D models but, I am also interested on 5D BIM, because as civil Engineer I was responsible to produce QTO and BOQ. As part of my degree I undertook a research about the barriers to the 5D BIM adoption and the existing procedures to export the QTO from a 3D model to costing programs.

Some interested conclusions could be get from the research. There are still many barrier to 5D BIM adoption, such as: Lack of digital skills, Lack of knowledge of the operation of the BIM methodology, Fear of the unknown and to assume new roles, Lack of QS expert knowledge in the BIM/5D BIM. The existing process to export the QTO still required manual interventions for an efficient automated process, but we are on the way. I would like to give updated information about the 5D BIM and encourage people to apply this methodology.

 What to expect during the event

The fact that the BIM methodology is becoming widespread among designers and builders in Ireland, many contractors and QSs find it difficult to implement 5D BIM for QTO and costing.
There are multiple reasons and issues for the 5D BIM adoption, most of which could be addressed through education and training of the company’s staff. Additionally, QSs must be able to understand how 3D models works, to acquire new digital skills and collaborative practices.
The findings presented herein that the current processes to export QTO improve the productivity but still require considerable manual intervention and digital knowledge, which constitutes a barrier for the adoption of 5D BIM.
Finally, the data analysed in my research are promising and suggest that professionals of the AECO sector, understand that the BIM methodology represents a significant technological change that is transforming the way of producing and sharing information.

Key Learning Objectives

- Point out the main barriers and difficulties in implementing 5D BIM.
- Give recommendations that will enable contractors to fully use BIM for more effective 5D costing.
- To identify how QTO, and BoQ processes could be assisted by the implementation of 5D BIM.
- Point out the current procedures to export QTO from 3 D models to costing software.
