Answer: A. Concreting of roof slabs
Explanation
Roof slabs must be fully concreted before subsequent structural layers or finishes can be placed. Concreting provides the structural deck required to support masonry parapet walls above. Logical construction sequencing dictates that structural framing precedes finishing and masonry work. Building construction follows strict chronological sequences from foundation to roof completion. Roof slab construction involves formwork erection, reinforcement placement, and concrete pouring. Parapet walls are masonry barriers constructed along the outer edges of roof terraces.
Civil engineers schedule roof concreting carefully to ensure proper curing before wall loading. Proper sequencing prevents rework and protects workers during multi-story building construction. Construction managers coordinate structural and finishing trades based on logical dependencies. Option B represents a terrace finishing layer that must follow structural slab completion. Option C occurs before concreting takes place to support the wet concrete mixture. Option D describes parapet wall construction which requires a completed roof slab base.
