Appropriate waste management at construction sites is one of the major challenges general contractors have to face. Subcontractors are also responsible for waste generated by them and their proper storage, disposal and final management. Waste management of a project is regulated by Waste Management Plan contained in BIOZ Plan. If hazardous waste is present, the contractor shall define that in the Safe Work Performance Instruction before starting the works and react in case of environmental emergencies and incidents.
The most commonly generated waste types are: dirt and rubble, rocks and waste from renovation and removal of constructions and road infrastructure. Many of those are reused in construction works, e.g., earthworks and finishing works. Appropriate waste management at construction sites and monitoring of potential harmful remains are coordinated on an ongoing basis, in laboratories located near the performed investments.
The process of construction is long and complicated and different type of waste is generated at each stage. For instance, during the initial stage of building deconstruction works, brick and concrete rubble is generated, in case of roads it is bitumen or old foundation material, while railway contracts involve track ballast.
As it was already mentioned, some waste can be reused. Removed dirt is a valuable material and is often used for finishing works. Removal of trees and bushes is reduced to a minimum, while the timber acquired during the process is managed by the investor. Bushes or branches may be used as biomass fuel or gardening material after chipping.
Detailed information on the amount of waste is provided in the tables at the end of the report.
 Due to their enormous volumes, soil and dirt are presented separately in data tables.
