Having New Garage built
I am having a new garage constructed on my property. Around here they are all tin sided and roof buildings. I have a choice of wood frame or 2x3" metal frame. It will have 2-9ft roll up doors. I plan to put it beside my shop which was built on cement block piers. Beside the shop is part of the concrete slab and part of the asphalt driveway.
It would sit 1/2 on each. They plan on bolting the bottom of the frame to the concrete and asphalt. Pressure treated wood or the metal.
A friend said I should dig up enough of the asphalt and make a footing because the asphalt will move.
The garage will be 20x25 with only the concrete and asphalt for a floor. I was just going to have a carport put up but the garage was not that much more and the cars would be completely enclosed.
The only thing of note is we do have high winds occasionally because I live on a bluff, although the shop which is built of wood with tin sides and top has held up fine with winds of 75mph. Although it has a lot of weight inside. The garage will have the shop 5ft on the left, a wood garage 15ft behind it and a house about 50ft to the right. So its pretty protected from the wind. Only the front will be venerable to direct winds but there is woods across the street, but will only be a shell.
Do you think I need to make the footings for the asphalt or will it be ok just bolted to the asphalt?
