In the areas where most of our projects are located, the city planning/engineering departments want a Site Photometric plan included with the submittal drawings, as part of their review for issuing a building permit. In the past we have hired an electrical consultant to generate that plan, and they usually send us back a PDF sheet with our title block, the site plan, and some site light fixture cut sheets.

The site plan they send us is more likely a CAD export, and then there's a grid of numbers and points across the whole site, representing footcandle levels on a 2-foot or 5-foot grid. I'm assuming this is some sort of AutoCAD plugin, using photometric data from the light fixture manufacturers.

Is there a way for us to make use of manufacturer light fixtures with IES data, and generate the photometric plan ourselves? It seems like these plans for city submittals are usually just a formality. I don't think they look at them real closely. So it would help our bottom line if we could generate such a plan ourselves instead of having to farm it out.
