Interfaces in Construction Processes serves as a practical aid for construction professionals on-site, helping them to quickly find balanced solutions to problems. The perspective is thematically focused on specific concrete issues. The authors avoid detached theoretical discussions and instead approach the problems through case studies. This highlights different viewpoints and approaches, as two authors (Braun, Nemuth) are experienced construction practitioners, while one author (Haentjens) is a construction lawyer. This provides the reader and user with an understanding that actions on the construction site not only involve the technical resolution of a (potential) conflict but can simultaneously lead to new (legal) issues. Content includes: Identifying one's own starting point and that of the contracting partner.
