3i Construction self-performs most, if not all, of their interior finishes where skilled tradesmen are directly employed for the rough carpentry, doors, frames, hardware, drywall, acoustical ceiling, and painting systems of the project. Some of 3i’s accomplishments include properties generally known for their high-end interior finishes. Some of these clients include Dallas Museum of Art, Hotel Inter-Continental, Gold’s Gym, Gateway Church, Bank One, Summit Dental Lab, Smoothie Factory, and a myriad of restaurants.
