Sweet Tea amounts for construction crew?

[HBMTN]

I have been catering for 3 years and rarely do people want me to do drinks. I have booked a catering for a construction crew lunch for 225 people which I am guessing mostly men. Can someone give me an idea of the ball park on amounts of sweet tea and ice I should need for this meal?

I figure 20 oz/person on drinks but I don't know on the amount of ice.

figure 1 liter per guy of tea if its going to be a hot day thats 4 cups of tea
ice -6 cubes per guy.
