What Interior Construction Group does

Interior Construction Group (ICG) is a Chicago-based interior general contractor delivering commercial buildouts and renovations under a four-phase service model: pre-construction, construction, project administration, and post-construction. Project scope ranges from 3,000 sq. ft. to 170,000+ sq. ft., and the firm holds LEED-accredited delivery credentials and has been a U.S. Green Building Council member since 2005. The client base spans financial services (JPMorganChase, Capital Group, BlackRock, Madison Dearborn), professional services (Boston Consulting Group, Katten Muchin), consumer brands (NIKE), telecom (AT&T, Motorola Solutions), and hospitality (Marriott), with several anchor relationships extending 20+ years.

ICG's revenue model is project-based fixed-fee construction services sold to enterprise corporate clients, supplemented by long-tail repeat engagements with select anchor accounts. The firm positions on green-certified delivery, relationship-driven account management, and the ability to execute large-floor-plate buildouts for institutional occupiers. In April 2024 ICG was acquired by Bulley & Andrews, a larger Chicago-based general contractor, and now operates as B&A | ICG.

Post-acquisition, ICG is investing in geographic expansion. In April 2026 the firm appointed Sujey Subramanian, formerly Deputy CIO at PAG, as Head of Asia-Pacific Corporate, establishing its first senior position outside the United States. The hire points to an APAC delivery capability targeted at U.S. asset owners and institutional investors with cross-border real estate programs, with PAG as a likely anchor relationship. No AI/ML, software, or proprietary technology components are disclosed in the operating model.
