To qualify for the Master Builder - Structures certificate: You must construct twelve scale structures: At least six different types of structures must be represented in the total.
The intent of this requirement is show that you can model a variety of types of structures, not just several variations of the same type. For example: a wood frame station and a brick station would be different types, but a wood frame station from Kansas and wood frame station from California would probably not, unless you could show that there was a substantial difference in the construction. When in doubt, why try and split hairs? Instead, try your hand at building something completely different. You might learn some new modeling skills in the process, and who knows? You could even have fun doing it!
One of the six types must be a bridge or trestle.
Before you panic with visions of elaborate wooden trestles dancing in your head, stop for a moment and consider just how many different types of bridges and trestles there on or around a railroad. Remember, your bridge doesn 't have to span the Grand Canyon; a short span over a creek or dirt road may be enough. The point is to demonstrate that you know how to build a bridge that is appropriate and will support the load that it has to carry. If there is no place on your layout for the tracks to cross a bridge, how about a bridge that carries something else? You could replace a grade crossing with a bridge that carries the road up and over the tracks (as many prototype railroads have been doing in recent years), or build a foot bridge like the ones over many rail yards Finally, remember that you can even build the bridge as a separate model - it doesn 't have to go on your layout.
At least six of the models must be scratch built. The following parts are specifically excluded from the scratch built requirement (although you may scratch build them for additional points): Light bulbs & electronics; paint, decals, figures; and basic shapes of wood, plastic, metal, etc.
Something that you should remember if the idea of "scratch building" intimidates you: There is very little difference between scratch building and building most craftsman kits. The big difference is that in a kit the manufacturer has assembled the materials that you will need, for you. Only the construction needs to be done from scratch. If you take someone else’s plans and instructions (even those from a kit) and go to the hobby shop and buy the materials yourself and assemble them, that qualifies as scratch building. On the other hand, if you do develop your own plans, make sure that you tell judges that, as it will earn you extra points.
The remaining six, if not scratch built, must be super-detailed with scratch built or commercial parts (for extra points).
There are all sorts of ways to super detail structures. Look closely at what you are trying to model, and see the little details: signs, ladders, electrical fixtures, window details, roof details, etc. For buildings, including an interior (and a way to see it) is definitely recommended, with as much of it as possible scratch built for extra points. Including some sort of "scene within a scene" is a good way to catch the judges' eye. Adding detail to your structures will not only meet this part of the requirements, but will also add to your score, and to the overall appeal of your model.
One way to save money and increase your scratch building score is to buy only one of a particular detail part, and use it as a model to make the rest yourself. This means build the others yourself from scratch, NOT to use the commercial part as a master to make a mold to cast copies of it.
You must earn a score of at least 87-1/2 points on six of the twelve models in either an NMRA sponsored contest or in AP Merit Award judging.
Note that only six of the twelve must earn 87-1/2 points. The others don't even have to be judged! They do all have to be described on the Statement of Qualification (see below).
You must submit a Statement of Qualification (SOQ - available on the web and from the Regional AP Manager) which includes the following:
