Designer’s Notes:
1. The length of need point for the C-A-T system is at post # 4 while the length of need for the FLEAT-MT
is at post # 3. This point is shown for all three systems and only for informational purposes. To simplify
the determination of plan quantities, all calculations shall be based on values for the Brakemaster.
2. The length of need point (LON) for the Brakemaster is at mid-length; therefore, after calculating the
-4"
required LON for the barrier, deduct 16' [4978.5 mm] (plus the length of any required transition) from
the required barrier LON to determine where to actually end the barrier.
October 2006 B-12
Appendix B
Roadway Sample Plan Notes
Length of Need (LON) Deductions for Transitions
In order to simplify the calculation of plan quantities, the following length of need deductions
for transitions are based on the transition designs for the Brakemaster. The Brakemaster is
always shorter than the corresponding transitions for the C-A-T, or the FLEAT-MT.
Transition LON Deduction
W-beam Transition to Median Barrier Guardrail 0
W-beam Transition to Vertical Concrete for Median Application -7½" [4763 mm]
15'
-3"
3. The 6' [1905 mm] section directly behind the Type 1-98 shall be parallel to the centerline of the unit.
A maximum flare of 3 degrees (20:1) is permissible. A cross slope of no more than 8 % (5 degrees) is
recommended. (These criteria are based upon recommendations for the Brakemaster.)
4. Pre-approved shop drawings are reviewed and kept on file by the Office of Roadway Engineering
Services. Click on the Roadside Safety Devices icon on the Office of Roadway Engineering Services web
page at: http://www.dot.state.oh.us/roadwayengineering/ for the current Dwg/Rev. and ODOT Approval
dates.
5. Bidirectional should be specified for locations where traffic is expected to be in opposing directions on
either side of the barrier. Unidirectional shall be specified when traffic is expected to move in the same
direction on both sides of the barrier.
6. A 10-foot [3-meter] Minimum Lateral Clearance, measured from the face of the rail, must be provided
on each side of unit.
7. All curbs and islands should be removed for optimum impact performance.
8. The C-A-T, Brakemaster and FLEAT-MT are gating systems.

Roadway Sample Plan Notes
WHEN BI-DIRECTIONAL DESIGNS ARE SPECIFIED, THE CONTRACTOR SHALL SUPPLY
APPROPRIATE TRANSITIONS.
PAYMENT FOR THE ABOVE WORK SHALL BE MADE AT THE UNIT PRICE BID FOR ITEM 606,
IMPACT ATTENUATOR, TYPE 2-98 [(SPEED (IN MPH), HAZARD WIDTH (IN INCHES)),
(UNIDIRECTIONAL OR BIDIRECTIONAL)], EACH, AND SHALL INCLUDE ALL LABOR, TOOLS,
EQUIPMENT AND MATERIALS NECESSARY TO CONSTRUCT A COMPLETE AND FUNCTIONAL
IMPACT ATTENUATOR SYSTEM, INCLUDING ALL RELATED BACKUPS/BACKSTOPS,
TRANSITIONS, HARDWARE AND GRADING, NOT SEPARATELY SPECIFIED, AS REQUIRED BY THE
MANUFACTURER.
Designer Notes:
1. This note should be used for the protection of Type 5 Barrier Design Guardrail, concrete median barrier
and other fixed objects.
2) The payment item will list the required speed (in mph) for the attenuator and the width (in inches) of the
hazard to be protected. The designer must take care in using this and similar notes, realizing they are
generic notes covering specific products. Not all possible nuances of the products can be detailed.
Because of the wide variety of product configurations, the designer needs to consider the available
footprint of the impact attenuator for the speed and hazard width. On some occasions, for a specific
speed and width, only one company’s product will fit in the space available. In such cases, the designer
should specify only the appropriate product. However, on other occasions either the speed or width of the
product desired is only available from one manufacturer. In those cases, the designer could specify a
slightly higher speed or width so that the contractor has the option of choosing equal products from either
manufacturer.
3. The length of need point is at the nose of the system; therefore, the entire length of the unit can be
deducted from the calculated length of need for the barrier. Both products are non-gating systems.
4. Either system comes with units with either parallel sides or flared sides for the protection of wider
hazards. The designer must specify TL-3 configurations (tested at 62.1 mph [100 kph] or higher) for
installations on the NHS.
5. Pre-approved shop drawings are reviewed and kept on file by the Office of Roadway Engineering
Services. Contact the Office of Roadway Engineering Services for the current Dwg/Rev. and ODOT
Approval dates. The TAU-II application drawings in the previous table are limited to expected typical
configurations. The contractor is expected to obtain the specific drawing from the manufacturer, if the
TAU-II is the chosen product.
)
6. If cross slopes are steeper than 8% (12:1) or if the cross slope varies by more than 2% (1° over the
length of the unit, a leveling pad may be used.
7. The QuadGuard rear fender panels slide 30" [762 mm] rearward upon impact, so ensure the specified
width is adequate.
8. The TAU-II uses several types of backstops and is selected per application. Backstops can either be
attached directly to a barrier wall or a suitable structure (PCB Backstop on PCB or Flush Mounted for
connections a reinforced vertical wall (as shown on SCD RM-4.6)). Or it can be installed in a stand-alone
system (Wide Flange or Compact backstops).

Appendix B
Roadway Sample Plan Notes
9. Bidirectional should be specified for locations where traffic is expected to be in opposing directions on
either side of the barrier. Unidirectional shall be specified when traffic is expected to move in the same
direction on both sides of the barrier.
10. A wheel deflector assembly is required for all QuadGuard installations that are replacing GREAT or
sandwich systems that were installed with a concrete backup. They are also required at new installations
where the chamfered corners, as detailed on the pre-approved shop drawing for the QuadGuard System
with Concrete Backup (Dwg. No. QSCBCVR-U), have not been provided on the concrete backup.
These assemblies are not included in the cost of the QuadGuard and should be itemized separately as
Item 606 QuadGuard Wheel Deflector Assembly, Each.
11. A separate backup is not needed for a QuadGuard attached to a concrete median barrier end that is
shaped as detailed on Standard Construction Drawing RM-4.6. The designer should detail the ends of the
barrier per SCD RM-4.6 and include these details in the plans. Specify ITEM 606, IMPACT
ATTENUATOR, TYPE 2-98 [(SPEED, WIDTH), (UNIDIRECTIONAL OR BIDIRECTIONAL)], AS PER
PLAN using the above note minus the reference to backups in the “Payment” paragraph. Add the
following sentence: “The QuadGuard shall be attached directly to the concrete median barrier and detailed
in the plans, without the use of a separate backup.”
12. Each of the Type 2-98 products have a wide variety of related units (families), typically covering
various design speeds (number of bays) and protected widths. The designer should also identify on the
project plans for each unit specified on the plan any "optional" items needed to construct a complete
device. They include:
- The design speed and hazard width the product for which the product is providing protection.
- Available foot print area for the product. Each of the products are of different lengths, and at certain
speeds and widths, a one or more product may not fit the space (i.e. gore nose) to still obtain required
lateral clearance from the traveled way. If this area is identified on the plans, for each occurrence, it
then is up to the contractor to select a product that is rated for the location, and still fit into the site.
- Foundation type (asphalt, concrete, bridge deck)
- Transition type (concrete barrier or guardrail), and
- Backup support. A standard concrete backup is detailed on SCD RM-4.6. Otherwise,
s
specify an independent stand-alone anchorage like the product' own concrete backup, or
its tension strut backup.

Notes:
1) Test Level 3+ refers to the fact that some units have been tested or are accepted for test conditions
that exceed normal Test Level 3. Additional testing included a 2000 kg. vehicle impacting at zero degrees
at 70 mph.
2) The width of the WideTRACC-L and -R can be increased by adding approved wing extension on one
side. The extensions will add 28 inches of length and 3-7/16 inches of width for each section.
3) The width of the WideTRACC-B can be increased by adding approved wing extension on both sides.
The extensions will add 28 inches of length and 6-7/8 inches of width for each section.
4) Flared units are flared on one side only. For example, looking from the front of the unit, a
WideTRACC-L will have parallel sides for the first couple of bays, but after that the left side will be flared
to accommodate a wider hazard. The right side of a WideTRACC-L will have a straight side.
