As variant

let
    Source = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
    words = {"plant", "materials", "subcontract", "labour" },
    adjustCost = Table.AddColumn(
        Source,
        "new cost",
        each
            if List.ContainsAny( Text.Split([description], " "), words )
            then [cost]
            else [cost]*1.03,
    type number )
