The project aims to enhance the property through targeted painting, roofing maintenance, window treatments, and safety installations while ensuring strict compliance with occupational health, safety, and quality standards.

• Applying torch-on waterproofing to the roof, inclusive of UV protection.
• Supplying and installing window blinds across specified rooms.
• Providing Class B and C 9KG fire extinguishers and installing safety signage.

All activities are to be conducted on-site, with access granted only upon prior coordination with institute maintenance personnel. Temporary works require prior approval, and all materials must meet current SANS standards, municipal by-laws, and manufacturer specifications.
