SITE PREPARATION – ALL FOUNDATION TYPES
• Assist the customer in selecting a site which
allows easy access to and from the scale,
ensuring enough area for straight and level
approaches, and to meet all State and Local
Weights and Measures Regulations.
─
The site needs good drainage away from the
scale, elevated enough so the surrounding
areas drain away from the scale site.
─
Obtain all the necessary permits and licenses
prior to beginning construction.
Scale Positioning
• Position the scale so that vehicles can approach and exit the scale easily and
straight.
─
Smooth and level approaches are required at each end of the platform to
reduce loading shock, and to facilitate testing of the scale.
─
Approaches must conform to the requirements of the law in the state in which
the scale is being installed.
─
In the absence of such laws, the approaches must conform to Paragraph
UR.2.6 of the
National Institute of Standards and Technology Handbook
44 , which states that the first 10 feet must be level and on the same plane as
the scale platform.
• The platform should be visible from the instrument location.
• Surface water must drain easily, and not collect, under the scale.
• The substructure must have a minimum bearing pressure of 3000 PSF, or as
specified on the Fairbanks Certified Prints .
