I'm going to build a sign on my land that is approximately 30m x 12m and 3m above the ground.I want to design and construct it myself, so please look at my plans and tell me what I need to improve/fill in the blanks.16m I-beam (x12) (12m high sign + 3m above ground + 1m below ground to footings)Corrugated sheets for panel face30m steel pipe (x12) (to run horizontally to connect the corrugated sheets, and then I-beams connect to steel pipes)Footings (spread footings)excavate 1m for the footings using excavatorcompact soil using vibrating plate compactorpour concrete for footing?how do I make the footing and attach the I-beams?place sign structure with a crane truckThanks, and if I successfully make it I'll send some money to whoever helped me the most in a few months.
How many verticle I beams are you using? The foundation needs to go below the frost line. The strength depend on exact conditions of soil etc. However 1 meter does not seem deep enough for that size sign. But it depends on the spacing of the I beams. Also depends on where the sign is and what damage it may cause if it blows over.
