Atlantic self-performed over 70% of all work with in-house crews, managing 12 specialty subcontractors and performing 100% of project supervision, safety, and quality control. Detailed phasing and traffic control plans preserved parking capacity, ADA access, and pedestrian safety, with many operations performed at night or off-hours to avoid disruption. Despite a 32% increase in contract value, Atlantic delivered all three garages one month ahead of schedule, with zero recordable safety incidents and full compliance with WMATA and federal labor standards.
