Construction is one of the sectors that makes a significant contribution to economic development, but at the same time a sector that is extremely sensitive to crises and market disturbances. In the Republic of Croatia, the construction sector accounts for about 5% of the total Croatian GDP.

Three brands with which it operates were selected for the analysis, Rigips for dry construction, ISOVER for insulation solutions and Weber for facade solutions.

The analysis showed that the Saint-Gobain company, as an example of all three brands, implements effective procurement management and continuously strives to improve business processes.
