Pushkin Square
Foundation Works Near Cultural Heritage
The brief
Foundation pit reinforcement at Gudiashvili St. 1, directly adjacent to the Shalva Amiranashvili House of Georgian Art Museum — a state-protected cultural heritage monument. Commissioned by Tbilisi City, the project required absolute precision: any structural vibration could irreparably damage both the 19th-century building and its irreplaceable collection.
The challenge
The construction site shares a property boundary with a heritage-listed museum housing the national art collection. Georgian law prohibited any construction technique capable of transmitting vibration to the adjacent structure. Conventional percussion or vibratory pile driving were simply not an option. ERTI needed a solution that was both technically sound and legally compliant with heritage protection regulations.
Our approach
ERTI deployed a Giken Silent Piler — the only certified zero-vibration sheet piling technology available globally. The press-in method works by gripping previously installed piles and using their reaction force to press the next pile into the ground, generating zero dynamic impact. Throughout the entire works, the Shalva Amiranashvili Museum remained open and completely undisturbed.
