What are Missouri Temporary Concrete F-Shape Barrier Specifications?

Tips & Advice

The Missouri Highway and Transportation Commission outlines specifications regarding the proper dimensions for concrete F-shape barriers, including general notes, plan view details, elevation details, section details and connection details.

Missouri Temporary Concrete F-Shape Barrier General Notes

The Missouri Highway and Transportation Commission’s general instructions are as follows:

  1. All reinforcing should meet the requirements of CRSI except where shown on the plans.

  2. Reinforcing steel clearance to the edge of concrete should be 1-3/4” unless otherwise shown on the plans.

  3. At no time should the barriers be lifted or moved by use of the loop bars.

  4. Furnished sections should comply with dimensions shown, as approved by the engineer.

Missouri Temporary Concrete F-Shape Barrier Specifications

F-shape barriers in Missouri should conform to the following dimensions and include the following features, according to the Missouri Highway and Transportation Commission’s specifications.

Elevation View

The length of each barrier should measure 12’-6”. There should be two lifting slots on each barrier, spaced 2’-0” apart from each other. Each lifting slot should measure 1’-6” long and 3” high.

There should be three loop bars protruding from each side of the barrier; there should be 3-3/8” (plus or minus 1/8”) when measured from the face of the barrier to the outside edge of the loop bars.
Loop bars on the left side of each barrier should be spaced horizontally as follows, from the ground line to the top of the barrier:

  • Distance between the ground and the bottom loop bar = 4-1/2”

  • Distance between the bottom and middle loop bar = 3”

  • Distance between the middle and upper loop bar = 1’-5”

  • Distance between the upper loop bar and the top of the barrier = 7-1/2”

These measurements should be inverted for loop bars on the right side of each barrier.

Optionally, include 4” diameter, 11 gauge steel round mechanical tubing sleeve holes. If included, these holes should be spaced 2’-0” from each side of the barrier.

Running vertically through the barrier are #4 A bars; these should be spaced as follows, from left to right, starting at the left edge of the barrier and ending at the right edge of the barrier: 2”, 9”, 8-3/4”, 1’-3-1/4”, 1’-9-1/4”, 6”, 8-1/2”, 6”, 1’-9-1/4”, 1’-3-1/4”, 8-1/2”, 8-3/4”, 9”, 2”.

Plan View

According to the plan view, each barrier should include the following bars: #6 E BAR, #5 C BAR, #4 D BAR and #4 A Bar.
Barriers should be 1’-10-1/2” wide.

Missouri Temporary Concrete F-Shape Barrier Section Details

F-shape barrier sections in Missouri should conform to the following dimensions and include the following features, according to the Missouri Highway and Transportation Commission specifications.

Section A-A

Section A-A outlines stirrup placement with bar reinforcement. Each barrier should include a ¾” radius edger with a 1” clearance. Similarly, there should be a 2” clearance between the top of the stirrup and the top of the barrier.

Section B-B

Section B-B shows the plan for an optional V-notch. According to this view, each barrier should include a ¾” chamfer and measure 8” wide at the top of the barrier and 1’-10-1/2” wide at the bottom of the barrier. Barriers should measure 2’-8” tall.

Section C-C

Section C-C details a void area for lifting, and a radius edger to prevent spalling.

Missouri Temporary Concrete F-Shape Barrier Connection Details

Connection Rod A36
Connection rods measure 2’-4” in length. They include a top plate that is 2-1/2” wide, located 2-1/2” from the top of the rod. Each rod is 1-1/4” in diameter, with a 5/8” diameter hole for a retainer bolt at the bottom. A bottom washer is optional. Retainer bolt and nuts are ½” in diameter and 6” long.
