wheel wells and undercarriages of the design
vehicles stated in the performance criteria
and to employ proven devices to regulate the
truck speed of the design vehicles. The system
has met the performance criteria when there

If the paved exit has any mud or debris on it,
it may be determined by the owner, owners representative
and peer bidders that the system has not met
the performance criteria.
4.2. The manufacturer
is solely responsible for the equipment performance.
Should the equipment not perform as expected,
including slowing the truck travel down to a
necessary speed determined by the manufacturer,
the manufacturer shall modify, add and/or alter
the equipment supplied at his/her own expense
until the system operation has met the performance
criteria. The owner will be in a position to
judge whether the altercations will improve
the system's performance and can at any time
halt the further changes of the manufacturer.
Should the performance criteria not be met after
the approved changes, the supplier shall remove
the system at no cost to the owner, and pay
for interim street sweeping contract deemed
fair by the owner/buyer. Additionally, the manufacturer
must compensate the owner/buyer for any and
all cost attributed to failed system's performance
as deemed a loss by the owner, and shall pay
the owner the cost to install another Undercarriage
& Tire Wash system selected by the owner/buyer.

recent standards of manufacturing detailed by
the following standards organizations, AWS –
AGA- ASTM –ASSHTO –ANSI- NEMA -UL
13.3. The
owner/ buyer requires that the provided system
successfully remove all amounts of mud and debris
from the truck tires within the confines of
the wash system. No mud or debris shall be left
on the vehicles tires once it emerges from the
wash. If there is loosened wet mud on the vehicles
undercarriages and vehicles tires after the

that the manufacturer employ a reputable independent
testing agency( local to the site) to concur
with the manufacturers claims and to provide
reports of the systems’ quality once it
is running.
The test that is required by
the owner if the owner requests it, is,
That no visible mud, dried
or wet, be present on the exit apron of the
tire wash system.
That no visible mud ,wet or
dried, be visible on the exit haul road after
the wash system of up to 1/4 mile after the
wash systems exit.
That no visible mud be found
on the truck tires or the undercarriage of the
trucks after the wash system.
Any mud or debris found on
this haul road after the wash shall be removed
prior to it becoming fugitive dust emissions.
A performance bond shall be
submitted with the bid in the amount of the
submitted bid.
