Rough framing is the basic need of any construction. Things you will need for the purpose are measuring tape, framing square, measuring square, chalk line, hammer, nails and saw.
A blueprint is a must before you even start. It is one important thing that many contractors face problems with. A good blueprint made by a person with a degree makes your job a lot more organized than you would have thought. Joist layout is the next step where you should consider the walls above to stay stud over the joist or roof rafter over stud so as to transfer the maximum possible load onto concrete support. You should know the general marks of framing ‘X’s and ‘O’s, where X denotes where a full stud goes and O where a cut stud goes.
Now after sheeting is done on the sub-floors, snap all the wall lines to decide where to layout your top and bottom plates.
