Design, review, supervision and retrofit of structures under the NSR-10.

DDES stays with the structure through every stage, in Barranquilla and the rest of Colombia: it designs it under the NSR-10 (Colombia's seismic-resistant building code), reviews other firms' designs, supervises construction and provides construction oversight (interventoría). When DDES designs a project, the independent design review is done by another firm, as Law 1796 requires.
