Crafting materials used for these items are obtained from the Construction Factory:

  • Timber drops when making Parquet
  • Sand drops when making Concrete Compound
  • Wire drops when making Cables
  • Sheet of Metal drops when making Roofing

Important! Note that Planks, Bricks and Reinforcements are both produced at Cargo Port and used in its other crafting recipes. So if your quests, for example, need both Planks and Wooden Beams, don't be surprised that one Plank will disappear for every Wooden Beam made.
