Update on Renovation Works in the Leonardo Building

[Infopoint]

Dear ICTP Community,

Please be advised that major renovation and modernization works are 
actively progressing inside the Leonardo Building. These projects aim to 
deliver upgraded, more functional facilities while significantly 
improving energy efficiency and building safety.

Below is an overview of the ongoing and upcoming works, along with 
expected impacts on daily operations:

1. Library Area
Status: Internal demolition is concluding, and the installation of new 
electrical and HVAC systems is underway.

Staircase Access: Civil works will take place around the staircase to 
brick up the current escape door and open the new main entrance to the 
Library. The staircase will remain open and accessible during these works.

Passage near LB-115: Work will begin in front of office LB-115 to 
construct a new technical space and a dedicated locker area. This zone 
will be securely partitioned, and corridor access to the stairs will 
remain open.

2. Office LB-115 Temporary Closure
WORK SCOPE: Demolition and reconstruction of the dividing wall between 
office LB-115 and the Library.

IMPACT: Office LB-115 will be unavailable for approximately one week 
during August.

3. Second Floor Restroom Closures
WORK SCOPE: Removal of asbestos materials in the restrooms adjacent to 
the Oppenheimer Room, required to connect the main air ducts between the 
Library and the roof. Includes the removal of asbestos by a specialist 
company in strict compliance with safety requirements.

IMPACT: Starting at the end of August, all restrooms in this area will 
be completely closed for a period of several weeks. The exact reopening 
date depends on statutory inspections and clearances from local 
regulatory authorities.

4. Windows & Exterior Façade Renovation
Scaffolding Setup: Starting August 18, scaffolding will be erected on 
the west corner of the building, spanning from the ground level to the roof.

Accessibility: The Dirac stairs, the terrace, and all other passage 
routes will remain open and fully secured for safe pedestrian traffic 
throughout this phase.

Window Replacement: High-efficiency, safety-upgraded windows will be 
installed in the original sea-side wing. The initial phase covers the 
Library windows and second-floor rooms (Oppenheimer Room, LB-232, 
LB-233, and LB-236).

Façade Repair: Repairs to the concrete elements of the exterior façade 
will take place concurrently to secure the structure and prevent falling 
debris.

5. Roof Works
Timeline: Starting in September.

WORK SCOPE: Construction of a dedicated rooftop technical zone to 
accommodate the new Air Handling Units (AHUs) serving the renovated Library.

6. Outages of the air-conditioning system during the August and/or September

WORK SCOPE: System integration and connections will require temporary 
outages of the air-conditioning system in specific areas.

IMPACT: Works are scheduled to begin during the last week of August, 
provided weather conditions permit (i.e., temperatures are not 
excessively high). Noise and dust in the area.

What to Expect & Safety Precautions
We are fully aware that these activities will generate significant noise 
and dust in certain areas of the building. We ask for your patience and 
understanding as we work through these necessary phases to deliver a 
modernized, comfortable, and energy-efficient building.

Please pay close attention to safety signage and temporary barriers.

Do not enter clearly marked work zones.

Thank you for your cooperation and support.
