What SDC does
Southern Development & Construction, Inc. (SDC) is a privately held heavy civil construction firm founded in 1994 and headquartered in Oviedo, Florida. The company provides three integrated service lines — underground utility installation, site development, and heavy civil contracting — for residential developers, commercial builders, and municipal governments, with an operational footprint concentrated in Central Florida. SDC's customer roster spans national homebuilders (Lennar, Toll Brothers, Mattamy Homes, D.R. Horton, M/I Homes, K. Hovnanian), major entertainment operators (Walt Disney World, Universal Studios Orlando), and municipal entities (City of Orlando, Orange County, City of Kissimmee, Seminole County, Osceola County).
SDC operates a fleet of more than 400 pieces of heavy and specialized equipment, including GPS-guided earthmoving machinery with grade control technology and an in-house service and repair facility. Project execution is supported by AutoCAD, AGTEK Earthwork Analysis, HCSS Estimating, Primavera P6, and MS Project, alongside an internal IT team that develops customized asset tracking, data capture, and reporting tools. The company maintains a $250M+ aggregate surety line with National Surety at an A+ rating, alongside established banking credit facilities, supporting participation in large-scale public works and design-build projects.
Revenue is generated through project-based contracts — competitive bidding on public works and negotiated or design-build arrangements with private developers — structured as lump-sum or unit-price agreements. Pricing is fully customized per project scope and not publicly disclosed. GTM is sales-led and relationship-based, with a dedicated Business Development & Communications function, sustained client engagement with repeat enterprise customers, and project galleries and quarterly newsletters used for pipeline development and brand reinforcement.
