    Kagi summary:

    Kagi summary:

    This video discusses the use of lightweight fills in heavy civil construction, such as embankments and retaining walls. These lightweight fills can be made from wood fibers, shredded tires, expanded shale and clay aggregates, foamed glass aggregate, cellular concrete, and expanded polystyrene foam. These materials are used to reduce the loading on soft soils below roadways and protect underground utilities from damage, as well as reduce the lateral pressure of retaining walls. The use of lightweight fills can significantly reduce the size of piles, use a more-commonly available grade of steel, and simplify the tie-back system, saving money on construction projects. An example of this is the Port Canaveral expansion project, which saved $3 million dollars by using lightweight fill. Additionally, EPS foam is a popular choice for lightweight fills, but it has some downsides, such as its susceptibility to fuel spills and its thermal disconnect from the pavement.

      Whoa, Kagi can summarize videos? I wonder how it manages that? Unfortunately there doesn't seem to be anything about how it works on their summarizer page. :(

        I'm guessing it downloads the transcript somehow, if there is one.

          Hmm. It reads the closed captioning somehow, maybe? Seems like that is available via the API.
