Progressive Model Design will estimate every job separately, and many factors affect the total. Our labor rate is actually quite low when you consider the artistic talent you are paying for. Unfortunately, most of our modeling tasks take time (sometimes a great deal of it), and although we have applied as much automation to the process as we can, there is no way to really speed up the detailing process.
Consider a simple commercial building kit made of injection molded styrene….
Every structure kit will be painstakingly prepared by hand--trimming and sanding all pieces where necessary. The pieces are then washed to remove molding films and then airbrushed with at least 2 coats of model paint. After the color coat has dried, contrasting color coats may need to be applied. Windows, doors, fascia and trim often need to be hand-painted by brush. The walls will be fixtured so they remain square and then glued together. Glazing will be applied to the windows. Light blocks will have to be added to the interior if individual rooms are to be illuminated. Lamps will need to be installed and wired. Finally, after all construction is complete, details and signage are added to the structure and mortar detail applied to the brick. One or more final passes with the airbrush, dry-brushing with highlight colors and application of powdered chalks add the weathering necessary for a truly Proto-Realistic™ building. And then… we still need to install it and blend it into the existing scenery base. We're good, but this is no half-hour job.
Or how about a commercially available, out-of the-box tree by Woodland Scenics. Sorry, we don't use them. We do use Woodland Scenics products. But every tree is hand selected and the branches adjusted for variety. We then remove portions of the factory foliage to give them a more 'open' look. Highlights are applied using ground foam and paint to vary the uniform appearance. The base is trimmed square and a hole to receive a mounting pin is drilled in the trunk. The pin is glued in place and the trunk is sprayed with a flat finish to knock off the shine. Quite a bit of time, when you consider the hundreds or perhaps thousands of trees that go onto a layout. And this is only our B grade of construction I am describing!
The following numbers are just approximate and assume a 'very average' layout with about 10 - 15% trackage and yards, 15 - 20% structures and the balance just general, simple scenery.
Prices start at about $70 - $95 per square foot for a B Level HO or O scale layout. This would include basic benchwork, roadbed and track. N scale layouts are about 50%--75% higher on a square foot basis. A or AA level quality will add 15% and 35% respectively.
The basic scenery portion of a layout (rolling hills or flat areas with grasses, dirt and gravel coverage) will add from $25 - $50 per square foot over the base price depending upon the amount of contouring. Extensive rock outcroppings or cliffs/canyons will be $55 - $100 per square foot or more additional depending on the extent of vertical coverage and level of detailing. Streams, rivers and lakes will add $35 - $90 per square foot over the base price depending upon the level of detail. Urban areas with their high concentration of structures, roads, streets, figures and details will add $55 - $120 or more per square foot to the base price depending upon the structure types and density. Hand-painted figures alone (which cost $3.00 - $5.00 apiece), of which there may easily be a dozen or more per square foot) make up a substantial part of the urban scene. The cost of the structures themselves is additional (see below).
Cost of structure construction depends a great deal on the brand of kit and detail level desired. For basic B level construction, and as a VERY rough estimate, you can use 6-8 times the retail price of the kit. For example: a Design Preservation Models kit selling for $14.95 in Walther's catalog would cost you $10.47 for the kit, and about $65.00 - $85.00 in labor to paint, assemble and detail. Another $35.00--$45.00 will be needed to place the structure and blend scenery around it. Level A construction may be about 30% - 50% higher and AA will be at least 50% - 75% higher. Scratch-built Level AA structures will be quoted individually so that you can see our breakdown estimate of time and materials. Bear in mind, that each kit will be estimated separately, and factors such as size, fit, quality, type of construction, number of colors, trim, windows and doors and level of weathering will all figure in the final price. Generally, small, highly detailed buildings are disproportionately more expensive. Densely packed, urban scenes with multiple, small Level AA detailed structures can easily surpass $500 per square foot. Fortunately, most layouts incorporate only small sections that require this level of labor and detail and the average cost for the whole layout is substantially less.
Based on our prior projects, and when everything is added up, an average B level layout may cost between $225.00 - $275.00 per square foot. 'A' level will likely be between $250.00 - $300.00 per square foot and our 'AA' level can run as high as $350.00--$400.00 per square foot. But remember, PMD does not quote by the square foot. EVERY project is estimated individually and we will do our very best to stay within your budget.
