One book
that has good measured drawings is "Contemporary Classics -- Furniture of the Masters" by Charles D Gandy, FASID and Susan Zimmerman-Stidham (Whitney Library of Design, 1981). The views are without dimensions but the text gives overall measurements of the pieces. The Barcelona chair and ottoman are incuded.
Is this what you want?
Use the link and click on the "dimensions" tab to the right of the chair.
