conduits, etc., shall be coated with a cold galvanized paint containing at
least 95 percent zinc by weight.
3.2.7 Other Requirements
Install the system in accordance with the standards for safety included in

3.2.8 Incidental Infrastructure
**************************************************************************
NOTE: Provide drawing showing all contract
requirements for incidental infrastructure, e.g.,
shoulders, curbing, shoulder to curb transitions,
guardrail, and other passive barriers. Passive
barriers must transition towards active barriers in
accordance with Standard Drawing C9.02. Gaps and
offsets between active and passive barriers must
prevent a threat vehicle from traveling between
barriers. Active vehicle barriers must be installed
in a curbed section. If no curbing exists, a
shoulder to curb transition of 10:1 must be
introduced prior to and after the active vehicle
barrier. All appurtenances must have lateral offset
no less than 600 mm (2 feet) as noted on Standard
Drawing C9.02 except in the absence of curbing or
where speeds exceed 64 km/h (40 mph), in which case
offsets and clearances must be compliant with AASHTO
RSDG-4. All passive barriers not identified as
crashworthy per NCHRP 350 and AASHTO RSDG-4 must be
located outside of the clear zone as defined by
AASHTO RSDG-4.

Provide all incidental construction as shown on the Drawings. Incidental
construction shall be designed and constructed in accordance with
local/state DOT requirements,
AASHTO GDHS-5
,
AASHTO RSDG-4

the installed complete system has been calibrated, tested, and is ready to
begin performance verification testing. The report shall also include
certifications from the Technical Specialists of the Active Vehicle
Barrier, Traffic Controller Unit, and CCTV equipment/subsystems that the
