About Yullian Andrés

I am a professional specialized in modeling and developing civil engineering and architecture projects, with experience in infrastructure layout and design using ISTRAM ISPOL, surface and corridor modeling in Civil 3D, BIM modeling in Revit, and architectural visualization through 3D renders.

My work approach combines technical precision, geometric analysis, and high-quality visual representation. I like to understand the project needs from the beginning to develop efficient solutions, optimizing time, resources, and reducing possible interferences during the design and execution phase.

As a layout designer, I have experience in developing alignments, gradients, longitudinal profiles, cross-sections, quantity take-offs, and digital terrain models for road, urban development, earthmoving, and linear infrastructure projects. My mastery of ISTRAM ISPOL and Civil 3D allows me to transform topographic information into precise and functional models for decision-making.

In the BIM area, I develop architectural and engineering models in Revit, generating technical documentation, construction drawings, measurements, and interdisciplinary coordination. This allows my clients to have organized, up-to-date information ready for execution.

Additionally, I create 3D models and renders for architectural projects, generating visual images and presentations that help communicate ideas, validate designs, and facilitate project marketing.

My main value contribution consists of integrating topography, engineering, BIM, and 3D visualization into a single workflow, allowing my clients to obtain complete, accurate, and visually attractive solutions. I work in an organized, results-oriented manner with special attention to detail, ensuring quality deliveries and compliance with deadlines.
