IF this means quake proof and cyclone proof buildings, allow me to inform you that there are plenty of Dominican engineers and architects that build to international specifications.
Look at the houses in Barranca in La Romana for example. They are designed to hold up under a CAT 3 hurricane.
However, as to quake resistant buildings, I think you should locate engineer Orlando Franco (use google) and ask him. Most private constructions are fairly quake resistant. The only real failures during the 2003 quake that was 6.5 on the Richter Scale were public schools built under government contracts, where workmanship and materials are notoriously poorly supervised, plus one building that was privately built by a "maestro constructor" ...
