Study Notes
Building Lines
- Building lines represent the sides of a building, passing through the center of foundation posts
- Final layout is on batter board
- Builder must decide which lines to use.
Procedure for Foundation Lines
- Step 1: Transfer oriented line to batter boards using plumb bob, marking corresponding point
- Step 2: Locate center of foundation on opposite batter boards. Mark these points.
- Step 3: Stretch string #1 across marked points on batter boards; fix it and do not move during process.
- Step 4: Tie cord on string #1 to indicate original corner (A). Align this cord with corner stake using plumb bob.
- Step 5: Measure side along line 1 from corner A. Mark the new corner.
- Step 6: Stretch line #2 perpendicular to line #1, through the cord at corner A. Mark this line on batter boards.
- Step 7: Measure length of the building side along line 2, starting from corner A. Mark new corner (C).
- Step 8: From corner C, mark line #3 perpendicular to line #2.
- Step 9: Measure the length of the side along line 3, from corner C. Mark new corner (D).
- Step 10: Stretch line #4 across the opposite corner (B), parallel to line #1.
- Step 11: Check if the corners from the above lines form a square.
- After Steps above: Check if entire building is square using diagonal method if four sides are completely laid out.
