Over the last 2 days we have been focusing on form work. To start with we went out the back of the Tafe where there is plenty of room and set up a boundary with a string line and used a fence as the second boundary. After that we decided which plan we were going to follow and put a stake in the ground a few metres from each boundary. We made that the back corner of the house. From that we came forward the overall distance of the house and came in the same distance from the boundary and put a stake. Once we had the 2 stakes it got tricky because the fence at the back wasn't straight so we had to get the 2 overall lengths and use pythagoras to find exactly where the other back corner would sit after that the last point was easy.
Once we had all four points we came back of each stake and put pegs in the ground for hurdles but before we put the cross pieces on we went 170mm up on the hieghest point and then used the level to get them all the same. As soon as the hurdles were up we went about marking exactly where the ouside walls would sit. At first i found it really easy but when we came back and made sure every thing was right we came into problems. We started changing things and in the end it turned out we were changing the wrong things but as soon as the back wall was squared up using pythagoras and everything was adjusted again it all worked out good.
Once the outside walls were done we started putting in more hurdles for the other walls and before long the outline was all stringed out. I felt that i was really switched on during this step but i dont think it would of made a difference if we didn't have pythagoras. i learned that pythagoras is the most accurate way to make a right angle and the bigger the triangle the more accurate still.
