Luxury Condos Near Completion

In News - Projects by adminLeave a Comment

ISI has been providing construction and testing for the $620M Lumina at 201 Folsom Street. The Lumina is a luxury condominium development that consists of four buildings–two towers of 37-stories and 42-stories and two mid-rise plaza buildings of 8 stories each–for a total of 656 residential units. ISI provided full-time inspections and materials testing for the underpinning, reinforced concrete, post-tensioned slabs, structural steel welding, anchor proof load testing, and fire-proofing. The three-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 provide shear.

The ISI team uses iPads and a proprietary cloud-based management system, GreenBox, to speed reporting and help keep the project on schedule
