The contract start date is February 5, 2027. The contract end date is July 13, 2027. The total duration of the contract is approximately 5 months and 8 days.

Key milestones mentioned are Quality Gate (QG) phases:

• QG 1 takes place at the beginning of the service. For construction work (AN Bau), this is before the physical construction begins. For equipment technology (AN Ausrüstungstechnik), this occurs after contract signing, focusing on contract takeover, completeness of basics, and start of service.
• QG 2 occurs during the service delivery, ideally at the midpoint of the contract duration. For contracts longer than one year, multiple QG 2s are planned, with the possibility of up to two additional QG 2s per year. An extra QG 2 is also conducted if there is a change in the project leader responsible for the contract.
• QG 3 is held at the completion of the service, after the contractually agreed acceptance of the overall service and before the final invoice is submitted.

Detailed timelines for specific construction measures within this period include preliminary work, main work, and follow-up work for different locations like Gleis 303 Bft Dortmunderfeld, Gleise 304 u. 305 Bft Dortmunderfeld, Weichen 503 u. 515 Bf Do-Lütgendortmund Gbf, Weichen 504, 505, 513 u. 514 Bf Do-Lütgendortmund Gbf, Weichen 601 u. 602 sowie Gleis 602 Abzw Do-Lütgendortmund Gbf Flm, and Gleis 613, 614 u.
