The more parties that are involved in contracts, the more time-consuming and costly the contract documentation and orchestration of the stakeholders becomes. Additionally, in the course of construction, the involved parties modify contracts quite often, for example by extending the contract or splitting it into smaller more complex contract landscapes. Mutual agreements might lead to changes of existing parts of the contract itself. Another key driver is regulatory changes that need to be implemented and require adaptation of existing contracts, as a handover using the existing agreements might be contra legem.
