About this file
This file contains Federal Lands Highway (FLH) Standard specifications for concrete headwalls and related structures used in culvert installations. The document provides detailed engineering standards, construction drawings, and material quantity tables for various culvert configurations.
The specifications cover concrete headwalls for single and double pipe culverts ranging from 48 inches to 180 inches in diameter, with provisions for square, skewed (15°, 30°, 45°), and sloped configurations. Standards 601-1 and M601-1 address basic headwall design with dimensions, reinforcing steel requirements, and concrete quantities. Standards 601-2 and M601-2 provide slope paving specifications for headwall installations. Standards 601-3 and M601-3 detail wingwall construction for concrete headwalls with multiple skew angle options. Standards 601-4 and M601-4 cover small pipe culvert headwalls for circular and elliptical pipes ranging from 6 inches to 68 inches. Standards 601-5 through 601-8 (and their metric equivalents M601-5 through M601-8) address single normal, single skew, multiple normal, and multiple skew configurations for larger diameter pipes (42 inches to 84 inches, or metric equivalents 1050 to 2100 millimeters). All specifications include detailed tables of quantities for concrete (measured in cubic yards or cubic meters) and reinforcing steel (measured in pounds or kilograms), anchor bolt specifications, chamfering requirements, and foundation preparation guidance. The standards are approved for use on Federal Lands Highway projects under FP-24 and FP-14 project categories, with specifications effective as of February 2024.

For installations with more than two pipe culverts, increase the dimension "L" and all quantities shown for double pipe installation by adding a length equal to dimension "B" and the incremental change in quantities for each additional pipe culvert.
For skews other than those shown, multiply quantities and dimensions "A", "B" & "L" for square headwalls by secant of the skew angle.
Final quantities will be determined by using the tables on this standard.
Do not order materials until the length, skew angle, and slope bevel in the field have been approved.

in quantities for each additional pipe culvert.
For skews other than those shown, multiply quantities and dimensions "A", "B" & "L" for square headwalls by secant of the skew angle.
For the skew angle shown, the dimension "S" and the quantities for slope paving are computed for a 1V:1.5H sideslope. To compute dimension "S" and slope paving quantities for a
1V:2H slope multiply the values for that particular skew by 1.24, and for a 1V:2.5H slope multiply by 1.49.
Final quantities will be determined by using the tables on this drawing.
Do not order materials until the length, skew angle, and slope bevel in the field have been approved.

in quantities for each additional pipe culvert.
For skews other than those shown, multiply quantities and dimensions "A", "B" & "L" for square headwalls by secant of the skew angle.
For the skew angle shown, the dimension "S" and the quantities for slope paving are computed for a 1V:1.5H sideslope. To compute dimension "S" and slope paving quantities for a
1V:2H slope multiply the values for that particular skew by 1.24, and for a 1V:2.5H slope multiply by 1.49.
Final quantities will be determined by using the tables on this drawing.
Do not order materials until the length, skew angle, and slope bevel in the field have been approved.
