Union Hospital commenced construction in 1992. Topped out in 1993 and officially opened in 1994, the hospital project broke another record in construction time. It is the first private hospital opened since 1971 and the first full-service private hospital in East New Territories.

Building of this premier medical institution had taken into account specific requirements in quality of materials, construction craftsmanship, and the demand for capacity to accommodate medical equipment and tools. This has enriched E Man's portfolio of construction capabilities nicely and is an endorsement of E Man's excellence in project management.
