Summary

The tender concerns the renewal of public space in Gasthuiswijk–Haagweg Zuid, phase 4, in Leiden.

The estimated value of both phases is approximately EUR 5,000,000 excluding VAT, comprising a building-team budget of EUR 150,000 and an execution budget of EUR 4,850,000. The restricted procedure will select five candidates for the award phase. Participation requests must be submitted by 29 September 2026 at 10:00.

The contractor must also meet the specified insurance, experience, certification and documentation requirements.
