The firm has also extended into healthcare, industrial, library, sports stadium, and mission-critical construction, and has participated in joint ventures on marquee municipal projects such as the Columbia Metropolitan Convention Center (with MB Kahn) and Segra Park (with the Columbia Convention and Entertainment Bureau).

Operationally, CDI runs a sales-led, enterprise-field GTM focused on direct engagement with decision-makers at school districts, municipalities, colleges, and religious organizations, supported by a corporate website and LinkedIn/Facebook presence. Project sizes range from approximately $1 million to multi-million-dollar programs, with revenue generated on a project-by-project, quote-based basis through fixed-price contracts and GMP arrangements. The company is headquartered at 6417 Fairfield Road, Columbia, SC, with a workforce of 11–50 employees, and is led by founder/CEO Nathaniel Spells, Sr. alongside second-generation VP of Operations Nathaniel Spells, Jr. No funding rounds, M&A activity, or AI/technology platform disclosures are present in the source material, and revenue is not publicly reported.
