G. Greene Construction recently completed renovations to over 18,500 S/F in the Main South Building at Children's Hospital Boston. The space was retrofitted to house a new inpatient unit. Not knowing what the exact needs of the inpatient space would be, the decision was made for the floor to be fit-out as a 'flexible' critical care unit. The 22-bed unit was designed to meet the needs of an intensive care unit, intermediate care program, step-down care or acute care if needed. Each room includes significant space so parents can stay overnight or longer with their children. In addition, state-of-the-art medical equipment booms were installed for patient care in order to give the rooms more flexibility. G. Greene finished the project in just over six months meeting an extremely aggressive schedule.
