Comer Construction began work on the Sinai Emergency Department expansion in July 2022, handling utilities, grading, curb and gutter work, sidewalks, and paving. DPR Construction serves as the project’s general contractor.

The $50 million expansion is designed to improve patient experience, and will ultimately double the capacity of the emergency department, expand the trauma center, and provide space for larger patient rooms.  


This job requires intense scheduling and coordination of accessibility for the hospital’s emergency room. The magnitude of the project’s scope and integrations with vital operating services require completion in phases.
