You are finishing a landscape area around a newly constructed building. The design calls for a 2% slope away from the building for drainage. What is the most effective method to ensure this specific slope is achieved consistently across the area?

Question: You are finishing a landscape area around a newly constructed building. The design calls for a 2% slope away from the building for drainage. What is the most effective method to ensure this specific slope is achieved consistently across the area?

Answer options: ✅ Establish a reference elevation point and use a transit or laser level to check points at measured distances

• Visually estimate the slope by eye from various vantage points
• Use the excavator's boom length as a consistent reference for angle of attack
• Rely on the natural contours of the existing ground

Correct answer: Establish a reference elevation point and use a transit or laser level to check points at measured distances

Explanation: Establishing a reference elevation point and using a transit or laser level to check grade at measured distances is the most reliable method for achieving a precise and consistent slope across a finishing area for proper drainage. Visual estimation and relying on boom angle or natural contours are not accurate enough for specific slope requirements.
