Financial concerns again forced him to revise his plans; the final design called for poured concrete walls, up to thick, faced with granite blocks. This Stony Creek granite came from the Beattie Quarry in Branford, Connecticut. The concrete mass was the largest poured to that time. Norwegian immigrant civil engineer Joachim Goschen Giæver designed the structural framework for the Statue of Liberty. His work involved design computations, detailed fabrication and construction drawings, and oversight of construction. In completing his engineering for the statue's frame, Giæver worked from drawings and sketches produced
Conservation-restoration of the Statue of Liberty agreed to a working relationship with the Committee. In June 1981, the Committee was incorporated as a non-profit foundation licensed by the state of New York to raise funds for the restoration effort.

The French consultants visited Liberty Island in May, June, October and December 1981, before presenting a preliminary white paper to the National Park Service on
