About Sebastian

I am a BIM Specialist and Structural & MEP BIM Modeler, with over 4 years of experience in complex infrastructure and building projects (airports, public and industrial facilities). I combine technical rigor in modeling and data normalization with the ability to lead and coordinate BIM teams, taking responsibility for deliverables, deadlines, and quality.

I specialize in developing BIM models LOD 200–500, preparing construction documentation, extracting and controlling quantities with PRESTO, interdisciplinary coordination, and detecting and resolving clashes using Navisworks, as well as advanced Revit modeling for structural and MEP disciplines. I work in collaborative BEP / CDE environments under ISO 19650, focusing on data governance and quality.

I have a strong focus on BIM automation and productivity, by developing scripts with Dynamo to standardize processes, reduce time, and minimize errors. I prepare models for interoperability with analysis and operation systems such as Power BI, SCADA, IoT, ERP, and CMMS, supporting Digital Engineering, Digital Twin, and BIM-to-AIM strategies.

I have experience in BIM technical direction, defining roles and workflows, supervising teams, and technical mentoring. I am characterized by my ability to communicate technical decisions to non-technical profiles and align discipline, planning, and budget objectives.

My professional approach is oriented towards reducing on-site risks, improving productivity, and optimizing OPEX, facilitating predictive maintenance and asset management with structured data for operation.

I am open to freelance collaborations and consulting in Digital Engineering, on national and international projects.

Highlighted projects include photovoltaic farms (up to 79.6 MW), international airports, and major public infrastructures in Colombia and Peru.
