Follow the measurements on the approved plan for your carport. Use the nail gun to attach the first hurdle to the sleeper. The height of the carport slab should be the same as the pavers, so make sure that the posts sit a little bit higher than the slab.
You need to take two measurements off your wall, from your approved plan, to make sure the string line runs parallel to your home. After marking the first measurement, use the hammer to drive in a piece of timber that you can tie the string line around. Measure the same distance out from your wall and hammer in a nail. Run the string line beyond the required length of the carport but don't tie it off.
Use two pieces of wood as a base and a piece of timber to measure the correct height for the carport. Mark this off with a pencil against the fence. Use the nail gun to secure a piece on the fence to mark the correct height.
To make sure the carport is square, measure the distance, so that it's parallel to the paving. Mark that distance and hammer in a nail. Run and tie off the string line.
Measure the distance between the string lines at each end to make sure that they're square.
Once the string lines are square, repeat the process to run two more parallel string lines.Use fluorescent spray paint to mark any possible trip hazards, like the string lines.
