The scope of work included extensive renovations to an existing corporate air facility located at Westchester County Airport, in Harrison, NY, as well as the construction of a new 15,000 square foot addition. The addition included a new building entrance, reception area and lounges, executive offices, and conference facilities, a new elevator, and emergency generator. All of this work was completed while this busy corporate air facility was in full operation. This required close coordination with owner and airport authorities to avoid any disruption of the facility.
