1. 1 Presentation 8: LOCATING A BUILDING ON A LOT

2. 2 Plot Plan Plot plan information typically includes: –Lot boundary lines. –Building position relative to boundary lines. Building setback dimensions –Elevations of building and reference points. –Existing and future site conditions.

3. 3 Setback Setback is the distance a building is positioned from the boundary lines.

4. 4 Setback House Driveway 30′  0″ 36′  0″ 40′  0″ 60′  0″ N 30′ from south boundary 40′ from west boundary House is 36′ × 60′

5. 5 Corner Stakes House Driveway 30′  0″ 36′  0″ 40′  0″ 60′  0″ N Corner stakes must be located.

6. 6 Corner Stakes House Driveway 30′  0″ 36′  0″ 40′  0″ 60′  0″ N Label them … #1#2 #3#4

7. 7 Procedure For Stake Layout Establish front building line (BL). Locate stakes #1 and #2 along front BL. Calculate diagonal using Pythagorean Theorem. Locate stake #3 using two tape measures. Locate stake #4 using two tape measures. Recheck the layout.

8. 8 Front Building Line (BL)‏ N Measure front setback distance twice and set temporary stakes with a string. 30′  0″

9. 9 Stake # 1 N Locate stake #1 by measuring from the side property line. 40′  0″ 30′  0″

10. 10 Stake # 2 N Locate stake #2 by measuring along BL the length of the building. 40′  0″ 30′  0″ 60′  0″

11. 11 Calculations Diagonal calculation from the Pythagorean Theorem. Building is 36′ × 60′ C 2 = A 2 + B 2 C 2 = 36 2 + 60 2 C 2 = 1296 + 3600 C 2 = 4896 C = 69.97142274′

12. 12 Calculations C = 69.97142274′ = 69 + 0.97142274′ 0.97142274 × 12 = 11.65707286″ 11.65707286″ = 11 + 0.65707286″ 0.65707286″ × 16 = 10.5 1316572 sixteenths C = 69 11 / 16 ″ 11 10.5 69′ 

13. 13 Stake # 3 N Locate stake #3 by simultaneously measuring the width and the diagonal. 69′  11 11 /16 ″ 36′  0″

14. 14 Stake # 4 N Locate stake #4 by simultaneously measuring the width and the length. 60′  0″ 36′  0″

15. 15 Final Stage N Recheck calculation and all measurements.

16. 16 Conclusion N Laying out building stakes is straightforward. 60′  0″ 36′  0″ 69′  11 11 /16 ″ 36′  0″ 40′  0″ 60′  0″ 30′  0″ C 2 = A 2 + B 2 C = 69′  11 11 / 16 ″
