It is the retrofit of a 3-storey reinforced conrete building in Athens, and involves the construction of large external and internal steel braces and new RC walls, whilst individual existing members were strengthened with RFP materials or steel plates. A large part of the project was the strengthening of the 1,000m2 slab below the ground floor, which was severely damaged (vertical defromations up to 6cm!) due to large vertical loads and poor design. The strengthening of the slab was carried out with a combination of shotcrete below, and FRP laminates above.

The project had a budget of more than 500,000.00€ and was completed in just 45 days in July and August of 2018.
