In Germany, approximately 30,000 public contracting authorities issue more than one million contracts for construction, service, and supply services each year, totaling around 250 billion euros. The authors introduce the fundamentals of procurement law and its practical application, covering everything from the announcement to the bidding phase and the award of contracts, as well as potential legal protection. With numerous practical examples, they illustrate the rules companies must follow to successfully apply for public contracts. The second edition particularly takes into account the changes in the Procurement and Contract Regulations for Construction Services (VOB/A). Although the work is filled with paragraphs, it is written in an understandable manner and provides many useful insights for business practice. A true guide for successful action.
