State of play on the use of building construction standards in Congo-Brazzaville
This work aims to assess the existence and use of local standards in the field of building construction in Congo-Brazzaville. Surveys were carried out among construction companies, design offices and construction control firms operating in the construction industry. The results show that, overall, design offices, control or engineering consulting firms have more knowledge about the existence of construction standards, unlike construction companies. Indeed, it appears from this study that the probability of knowing of the existence of Congolese standards in construction control firms and construction companies is very low compared to engineering firms. The evidence provided by our sample also shows that structures involved in technical studies and real estate expertise are less aware of the existence of Congolese standards. Also, we note that the rate of knowledge about the existence of Congolese standards is more recorded at the level of structures that use foreign standards (16.90% against 9.09%), than those that do not use them. These structures also have knowledge of the effects (negative or positive) on the use of these foreign standards on construction (22.22% versus 3.57%) in Congo. Construction professionals must take into account certain technical specificities related to natural and social phenomena in the implementation of their construction projects in order to avoid early depreciation of the works carried out.
