Self-perform Advantage Costello Construction self-performs about 30% of work, including site and concrete, which can translate into reliable schedule adherence, cost control, and potential collaboration on prefabrication or specialized trades with partners to expand self-perform capabilities.

Public Private Access Active in both public and private sectors along the Baltimore/Washington corridor indicates a diversified project funnel and opportunities to cross-sell services such as design-build and sustainable construction to universities, government facilities, and corporate campuses.

Sustainable Focus Explicit emphasis on sustainable construction presents a selling point for energy-efficient upgrades, LEED or green building certifications, and long-term operational cost reductions for clients pursuing modern corporate offices and urban infrastructure.

Asset Ownership Ownership of heavy equipment and a track record of completing projects on time and within budget positions Costello to propose competitive schedules and potentially offer bundled equipment or accelerated procurement services to clients.

Past Growth Signals Notable investment in a 10-story hotel asset in 2017 suggests capacity for complex, multi-story commercial projects and the potential to target hospitality, mixed-use, and larger-scale developments with similar risk profiles.
