Steel pilings and under-structure with the trestle mats as a deck above for Crawler Cranes and utility trucks to have access. Notice there is no daps or notches in the ends of the mats, they have an internal lifting plate for rigging purposes. This means the trestle floor (deck) will have no holes.
