Staging area with bridge laid
out and ready to go
Once the team begins to move their equipment and materials into the staging
area, the judges can start checking the members for compliance with the rules
using the judging checklist obtained from the bridge Marshal. The judging
checklist is to be printed from the scoring
Also ensure that all competitors are wearing the required safety equipment
correctly. See rule 10.2.4 for details.
Note: Everything that goes into the staging area is subject to the rules
whether it is used in the bridge or not. Any noncompliant item will be
Competitors are responsible to make sure that members, fasteners, tools,
piers, and other items are placed as specified in the rules.
Competitors are encouraged to be efficient in laying out their items so as to
not inhibit the flow of the competition.
After all the judging checklists has been completed and all items
checked, the team captain is to sign the bottom of the preconstruction
checklist. The team captain's signature indicates that they understand
and accept any penalties that have been levied. The team captain should be
given time to check the rules and make any appeals necessary to the head
judge before signing the form.
There are several common violations that seem to with disappointing
frequency. Some are design issues, others are either fabrication or
erection issues. The following sections are intended to warn bridge
designers and to alert the judges.
Rule 18.104.22.168: Member size
for larger views
It would appear that the majority of
violations to this rule result from designers pushing the specified limits. The
judges will try to orient that member in the most advantageous position
to get it in the box, but if it doesn't fit EASILY into the box a
penalty is imposed. It would be wise to allow a little "wiggle room".
Rules 8.2.3, 8.2.4, and 8.2.5: Bolt, Nut, and Hole
Bolts and Loose Nuts must not be modified in any way (they may be painted) from their purchased condition. Bolts may not be ground to a point on their ends. Nuts may be welded to members. Holes must meet certain requirements specified in the rules.
Rule 10.2.3: Tool Size
A tool must not weigh more than 15 pounds.
Rule 10.6.2: Items Layout
Read this section carefully! There are a number
of specific requirements about where particular types of items can be
Watch for how competitors layout their items in the
staging yard. Certain items are to be in designated locations in the staging
yard and nuts and bolts may be in contact with each other, however every
member, tool, loose nut and bolt must be in contact with the
ground. In the provided
image, some of the nuts and bolts are not in contact with the ground and
hence are illegal. This must be fixed before timed construction.
