Introduction to Taping

Summary

This UCLA instructional video covers the process of measuring horizontal distances using taping techniques. It details the necessary equipment, including steel tape, a tape clamp handle, plumb bobs, a force gauge, and a hand level. The video explains how to mark points, maintain proper tape tension, ensure levelness, and account for any slope. It also introduces 'brake chaining' for measuring distances longer than the steel tape. Clear step-by-step instructions are provided to ensure accurate measurements. The video encourages viewers to participate in UCLA surveying workdays to learn more.

Takeaways

• 📏 The video explains how to measure horizontal distances using steel tape in surveying.
• 🛠 Essential equipment includes steel tape, a tape clamp handle, two plum bobs, a force gauge, pins, and a hand level.
• 🎯 Start by unwinding the steel tape from the starting point to the end point, securing it with the tape clamp handle.
• 🔩 Ensure 10 to 15 lbs of tension at both ends using a force gauge for accurate measurements.
• 📍 Use a plum bob to check that the tape is directly over the starting and end points.
• 🔧 A hand level is used to ensure the tape remains level, particularly important for longer distances.
• 👥 For long distances, one person may need to hold the tape in the middle to prevent drooping.
• 📝 Record measurements by noting the whole foot at the starting point and adding inches and fractions from the end point.
• ⛓ For distances longer than the tape length (100 feet), break the measurement into segments and apply the same process.
• 📐 On sloped areas, position the tape at the highest point and use the plum bob and hand level to ensure level measurements.

Q & A

What equipment is required for measuring horizontal distances with taping?

The equipment needed includes steel tape, a tape clamp handle, two plum bobs, a force gauge, pins to mark points, a hand level, and a surveyor.

What is the first step in the taping process?

The first step is to unwind the steel tape from the starting point until the end of the tape reaches the end point.

How do you ensure the correct tension while taping?

Use a force gauge to pull with 10 to 15 pounds of tension at both ends of the tape.

What is the purpose of using a plum bob in the taping process?

The plum bob ensures that the steel tape is directly over the measurement point to maintain accuracy.

How do you ensure the steel tape is level during the measurement?

Use a hand level to check that the tape is level, especially if the distance is long, which can cause the tape to droop.

What should you record as the actual measurement?

Record the number at the starting point, which gives the measurement to the nearest whole foot. Then, note down the inches and fractions of an inch from the end point for the complete measurement.

What is 'brake chaining' in the context of measuring distances?

Brake chaining is the process of dividing the distance into segments of 100 feet or less when the total distance is longer than the length of the steel tape.

How is the measurement performed on sloped terrain?

Place one end of the steel tape at the highest point, then use the hand level and plum bob at the other end to ensure the tape remains level.

What is the purpose of the pins in the taping process?

Pins are used to mark the points where measurements start and end, and also temporary points in case of brake chaining.

Where can someone learn more about taping and other surveying techniques?

You can learn more about taping and other surveying techniques by attending UCLA surveying workdays.
