Dome of the Capitol

San Juan, Puerto Rico · Phase 1: 2001 · Phase 2: 2024

Historic dome and cornice of the Capitol Building in Puerto Rico
Problem

A terra-cotta cornice at the base of the dome required reinforcement and stabilization without adding heavy, visually intrusive intervention.

CINTEC solution

A custom anchoring solution was developed for the historic terracotta substrate and installed with careful detailing to maintain the architectural character.

Technical notes

The project is a strong example of low-impact intervention on a culturally sensitive building envelope, with careful substrate and geometry assessment. See the project PDF for the detailed case history.

Result

The dome and its cornice were conserved while preserving the historic fabric and long-term structural reliability.
