In Dallas, Texas I visited a nice car park concept, where the frame structure was a precast columns and beams used in combination with post-tensioning slabs.
The contractor of the site was a very effective one, preparing a new parking garage for the visitors of the Dallas Arboretum.
What was nice from my point of view was the effective and efficient use of column shoes and bolts, and also hidden corbels - Peikko´s PC Corbel.
The speed of the construction site was really good - the job had merely started in May when I was there and somewhere in August the cars would already flow in filled with tourists visiting the arboretum.
Precast can be fast !
