The project will be implemented in two lots:
Lot 1 – Roof Waterproofing Works: Includes the complete replacement of the roof waterproofing systems for both Buildings No. 1 and No. 3, including removal of the existing system, surface preparation, and installation of a new waterproofing membrane to ensure long-term protection against water ingress.
