ISCDF reviews new and existing public and private buildings and gives technical opinions regarding their structural safety and whether developments are in line with the law. We also financially support research institutions and projects that disseminate knowledge about building safety and the management of Mexico City’s Seismic Alert. Violations in administrative requirements and structural security standards are not unusual. These violations often come from errors, oversights, misinterpretations of the code and, in some cases, negligence by developers that want to cut costs. ISCDF is aware that many companies are responsible and pay for an exhaustive numeric and technical revision of their project. But we have also noticed several projects being built that do not comply with the code to various extents. Ideally, all new projects should be revised in-depth but sometimes investors fail to comply in an effort to maximize their profits.
