Structural and Seismic Review
Starting in 2003, the national building authorities require that building projects must be independently peer reviewed, from a structural perspective. Before construction can commence, the project drawings (architectural and structural) and specifications must be submitted for approval to the building department of the municipality where the site is located. Failure to comply with this requirement can result in sanctions imposed by the judiciary system.
These code provisions and seismic design requirements have proven beneficial to the built environment in Chile, and Rojas et al.  state: “The relatively good reported performance of modern structures in Chile can be attributed to the building codes and standards adopted by the country and the level of expertise of the design professionals." Several buildings with favorable post-quake performance are described in Table 4.
