Optimization of Land Property Area for Construction Investments in the Aspect of CE - Circular Economy for Civil Engineering

Circular Economy (CE) is receiving increasing attention worldwide and is increasingly seen as a major policy agenda item and a testing challenge, for the construction sector. New construction investment management models in the CE trend is analyzed by new designs building constructions with new output data for constructions with the use of new building materials containing a part of the recycling materials. This research paper aims to determine the enablers of a CE for sustainable development in designing and making upgrade of engineering solutions that include current projects for the protection of our planet from the thermal effect. Construction is a resource-intensive industry where a circular economy (CE) is essential to minimize global impacts and conserve natural resources. Research into the use of retaining walls and the use of recycled materials allows for the continuous development of the field of retaining structures. The article presents a method for optimizing the development area in mountainous areas by leveling the terrain and using a slab-angular retaining wall. The main topic of the article is land leveling, designing a retaining wall and presenting the use of recycled raw materials. The publication presents patterns and methods for designing a reinforced concrete slab-angular structure in accordance with EC7, as well as the possibilities of using recycled materials.
