  • CONSIDERATION OF PRECAST LID SHOP DWGS

    The purpose of LID panel:

    LID panels are most commonly used for covering up the openings on building roof areas and also some inner part of the building where the precast slab is required. It can be seen in locations like lifts, stairs, water tanks, etc.

    Manufacturing consideration of LID panels:

    • Viewing direction of the lid panel is either plan view or view from below. Depending on consideration of manufacturing difficulties and near face finish and different profile requirements, it may change as vice-versa.
    • If lifting eye/ hook is projecting outside of lid means, we have to view the face with lifting eye as near face for manufacturing purposes. (Refer lifting hook/eye elevation view)
    • In lift lid, lifting hook/ lifting eye needs to be provided if it needs to be cast in the lid. Lifting hook detail normally given in lift drawing. (Refer lifting hook/eye placement plan view)
    • We can provide face lifters and either top or side lifters used for erection, lifting off table and transportation purposes.
    • Face lifters were used for installation of the lid on site. Whether its need to be near face or Far face is decided by viewing direction.
    • Bottom connection of lid most likely by grout tube to its lower panel or In-situ.

  • Why Bubble Deck?

    Bubble Deck – What’s so good about it?

    1. It’s fast, really fast.

    If you can build something quicker, than translates into making money quicker. There’s a premium on speed.

    1. Less manpower

    Less manpower on site. That means less potential problems to deal with. Which eventually translates into money. Generally speaking, the problems and costs associated with a project are proportional to the number of people involved in it.

    1. Structural Benefits

    Bubble deck slabs, because they are filled with air, are significantly lighter. Also you can have wider spans – without as much column support. This is very desirable from an architect’s point of view.

    1. Cost of manufacturing

    The BubbleDeckGroup tout it as being cheaper to manufacture. Personally, I’m sceptical of this claim. I think it’s the same, if not more.

    1. Environmentally Friendly?

    They also say it’s more environmentally friendly. It probably is relative to other solutions, but I don’t think it’s actually helping the environment. It’s sort of like the marketing on a cigarette packet saying that it’s “healthier” than other cigarettes. It is probably healthier, but cigarettes as a whole, generally speaking are not healthy. 

    What are the costs?

    Everything has to be designed correctly and properly early on. This is not necessarily a bad thing. It forces designers to plan and think things out, before the actual construction. But if the design team does a bad job, you can be sure that the entire project is going to be delayed, and is going to be monumentally expensive.
