Structural check of a lightweight tubular roof over a fish tank.

Client: Salmones Austral, Caliboro hatchery
Region: Biobío
Year: 2026
Services: Structural engineering · LIDAR scanning, point clouds and BIM
Sector: Aquaculture and hatcheries

Isometric IFC model of the roof structure over a circular tank

Challenge

Design a lightweight roof for a circular tank using commercially available tubular sections.

Solution

Starting from the roof IFC model, we checked the members with a finite element model (deflections, vibration modes and member forces) and issued the drawings for review.

Tools

IFC, finite element model, NCh 433, AISC 360.
