| PART 3 | EXECUTION |
| 3.1 | EXAMINATION |
| A. | Verify Trench Excavation is ready to receive work, and dimensions, and elevations are as indicated. |
| B. | Commencing installation means acceptance by Contractor of existing conditions. |
| 3.2 | PREPARATION |
| A. | Excavation, Section 31 23 16. Hand trim to required elevations. Correct over excavations. |
| B. | Remove stones or other hard matter that could damage pipe embedment or impede backfilling or compaction. |

| C. | The minimum distance between taps is 24 inches, with a 5 degree stagger. Do not make service taps within 24 inches of the end of pipe. Install taps at 60 degress from vertical, or as authorized by COR. |
| D. | Service saddles are required on all taps except, 3/4 inch or 1" taps to new ductile iron pipe |
| E. | Grease all exposed bolts and nuts then apply polyethylene sheet and tape wrap. |
| 3.8 | INSTALLATION – WATER MAIN LOOP (SYPHON) |
