Thanks for posting the drawings... I see that pages 22 and 59 are for the basement. Looks like it was designed for 122 parking spots and it extended over the whole footprint of the building and the patio area to the south of the building right up to the pool.
Looks like plans are for both south and north buildings. Or they mixed pages up when the scanned it in. These plans were no doubt, paper in 1981.
