The Infinity is a luxury residential complex and has four buildings, 8-stories, 10-stories, 37-stories and the other 42-stories, which house 654 residential units. At 1.4 million square feet, this landmark high-rise project kept our inspectors busy. ISI provided full-time inspections and materials testing for the basement excavation, underpinning, reinforced concrete, post-tensioned slabs, structural steel welding, anchor proof load testing, and fire-proofing. The five-level deep excavation was in bay mud and consisted of a shotcreted soil nail wall system and reinforced concrete slabs and columns. The superstructure was reinforced concrete, post-tensioned decks, with a core wall system in each building which serve as shear walls.
