In terms of installation ease, which type of deck is preferred to reduce dead load?

The preference for a grid deck in terms of installation ease and reducing dead load is based on its structural design. Grid decks typically utilize a framework of beams and open spaces, which allows for significant weight savings compared to solid slab alternatives. They are designed to provide the necessary strength while minimizing material use, which results in a lighter overall deck.

The installation process for grid decks can be more straightforward due to their modular nature. Components can often be pre-fabricated and then assembled on-site, reducing time and labor. This ease of installation, combined with the reduction in dead load compared to heavier concrete options, makes grid decks an advantageous choice in situations where weight is a concern.

In contrast, other types of decks like concrete, reinforced, and composite decks often involve heavier materials, leading to increased dead loads and potentially more complex installation processes. Solid concrete decks, for example, are heavy and may require more robust support structures, while reinforced decks often demand additional materials to achieve the necessary strength. Composite decks, while efficient, can also add significant weight compared to a grid configuration, as they typically combine different materials that may not reduce the dead load as effectively.
