A building in danger of ruin is any construction or installation of any type, the total or partial collapse of which could jeopardize the safety of its occupants, its operators, and that of passers-by for neighboring buildings, even non-adjoining ones. .
The National Agency for Urban Renewal and Rehabilitation of Buildings Threatening Ruin is working on the condition of buildings threatening ruin in Casablanca and Marrakech. More than 16,000 constructions are affected in the two cities, respectively in the districts of Casablanca-Anfa, El Fida-Mers Sultan, Méchouar Kasbah and Sidi Youssef Ben Ali.
Buildings threatening ruin in Casablanca and Marrakech under the microscope of the Ministry of National Territorial Planning, Town Planning, Housing and City Policy. Indeed, the National Agency for Urban Renewal and Rehabilitation of Buildings Threatening Ruin is looking at the state of its constructions in the prefecture of districts of Casablanca-Anfa, Al Fida-Mers Sultan. In Marrakech, the districts concerned are located in the Méchouar Kasbah and Sidi Youssef Ben Ali districts. Thus, 5,000 buildings in Casablanca-Anfa are targeted. As for the Al Fida-Mers Sultan prefecture, the number of buildings concerned amounts to 8,000 buildings.
“The objective is to establish precise and exhaustive quantitative and qualitative data relating to the state of the built stock at the level of said sectors, through the carrying out of a technical diagnosis for the buildings concerned in order to define the necessary interventions allowing the cessation of the danger they represent, the collection of multi-sectoral data (socio-economic, land, architectural, etc.) relating thereto, as well as the integration of the buildings listed in a geographic information system (GIS), and the identification of priority actions to be carried out”, underlines the National Agency for urban renewal and the rehabilitation of buildings threatening ruin. On the side of the ocher city, the aim is to carry out a technical assessment for 3,000 buildings threatening ruin in the targeted districts.
Overall, three classifications are taken into account for the buildings concerned.
The first category (B1) targets buildings to be completely demolished. “Buildings which fall into this category are those which reveal structural disorders detrimental to the overall stability of the building and constituting a risk for users and whose conservation actions (reinforcement, partial demolition, etc.) are very costly or incompatible with the nature and/or heritage value of the building,” indicates the same source. The second category concerns buildings to be partially demolished (B2). These buildings can be preserved with partial demolition possibly combined with reconstruction or consolidation work. In this sense, the parts to be demolished include entire levels deemed to be precariously unstable or too degraded. They also include corners of the building presenting a risk for the occupants or for the neighborhood (balconies, parapet, guardrail, stairwell cover).
The third category (B3) covers buildings which do not concern the other two categories and whose conservation is necessary (heritage, historical building) or whose conservation is technically and economically interesting through structural reinforcement (vertical structure, horizontal structure , underpinning). It should be remembered that under the terms of Law 94-12, a building threatening ruin is any construction or installation of any type whatsoever, the total or partial collapse of which could jeopardize the safety of its occupants, its operators, to that of passers-by for neighboring buildings, even not contiguous.
According to the same law, it also concerns any construction or installation that no longer meets the necessary guarantees of solidity, due to the dilapidation of one of its main interior or exterior components or due to its construction on land exposed to risks. .
