What would you use a laser for in a collections construction?

• A. Setting proper grade
• B. Measuring distance
• C. Cutting steel
• D. Aligning manhole lids

Answer: (A)

Setting proper grade is essential in a collections project because gravity drives wastewater to flow downhill, so the pipe slope must be precise. A laser level creates a consistent reference line or plane along the trench, allowing you to transfer elevations from a control point to the pipe invert at various locations. By using a grade rod or laser receiver, you can adjust trench depth and pipe elevations to hit the target slope, ensuring the entire run maintains the correct incline and that manholes line up at the designed elevations. While lasers can measure distance or assist with alignment in other tasks, the primary use here is establishing and maintaining the correct grade for proper gravity flow.
