It will be interesting to see who throws who under the bus. if the owner can prove he followed best practises for building construction and maintenance while operating in compliance with government requirements, that could put the government on the hook for negligence.
The issue has never been the construction. That building has existed at least since the 1970’s and has withstand many things that have affected that area of the capital including hurricanes and earthquakes.* The fact that building was built when most construction workers were Dominicans is a sign it isn’t new.
The biggest things that point its original design getting compromised was the fire of a couple of years ago and, presumably, the redesign where many columns were eliminated. Once things like the fire happened, what the building was designed to withstand when it was built becomes irrelevant.
There is also the maintenance issue, though that goes had in had with the impacts of the fire and the presumably modification.
*Albeit they tend to be “lite” in SD. That’s one of the reasons the Colonial Zone still conserves most of the main buildings that we’re built in the 1500’s unlike other Dominican towns founded in that century. At one point La Vega was as opulent as SD and had many stone buildings, but the original LV was destroyed by an earthquake -a not so “lite” one and some of the ruins of the original LV still exist- while Colonial SD still exist. Basically, the same story repeats itself with Santiago, Azua, Puerto Plata and a few others though most towns were completely of wood. For example, Santiago also had many stone buildings in colonial times and now not one of the older ones are actually colonial. In fact, the only colonial thing in Santiago is street grid layout in the “center of the center” including the shape of all the parks such as Duarte (though in colonial times they were not parks as now, rather a square with no distinction with the streets and absolutely nothing in them, not even trees.)
