Which statement about measurement of sewer pipe for payment is not true according to CALTRANS specifications?

• A. Pipe bends are measured along the outside edge of the bend
• B. Pipe lengths are measured along the centerline
• C. Fittings are paid for as installed
• D. Joints are measured by the number of straight runs

Answer: (A)

CALTRANS measurement for sewer pipe payment uses the centerline of the pipe as the basis for length. Bend lengths are measured along the centerline, not along an outside edge. The idea of measuring bends from the outside edge would distort quantity because the outside edge length varies with pipe diameter, while the centerline arc remains the consistent reference. Centerline measurement keeps payments uniform across pipe sizes and matches how the rest of the pipe is quantified. The other statements align with CALTRANS practice: lengths are measured along the centerline, fittings are paid as installed, and joints are counted by the number of straight runs.
