Full-Size Projects

Req 9 — Choose Your Big Build

9.
Working in a group, (or individually with the help of your counselor) build a full size pioneering structure, using one of the following designs in the Pioneering merit badge pamphlet:Carefully plan the project, assembling and organizing all the materials, referring to the points under Safe Pioneering, and complying with the height restrictions in the Guide to Safe Scouting.

You must choose exactly one option for this final requirement. This is the capstone build of the badge, so your job is not just to pick the most impressive-looking structure. Pick the one your team can plan, anchor, and build safely with the time, space, materials, and skill level you actually have.

Your Options

How to Choose

Choosing the right project

Match the build to your team and site
  • Time available: A service gadget or simpler bridge may fit a short camp window better than a more ambitious tower.
  • Materials on hand: Count the number and length of usable spars before choosing a design.
  • Ground conditions: Soft, rocky, or uneven ground can change which anchors and structures are realistic.
  • Skill level of your crew: If your team is still learning clean lashings, pick a design you can build well instead of one you can barely finish.
  • What you want to learn: Bridges teach load paths, towers teach bracing and height discipline, and kitchens teach useful camp design.
