GPD doesn't do the actual construction. The jobs are bid out and area GCs and subcontractors are hired for the construction phase. GPD does the site design and engineering as well as project management up through the permitting phase. Pretty much everything up to the point where dirt starts to move.fwiw the contractor mentioned in the Sep2018 Oneonta Planning Board minutes was GPD Engineering.

of course that doesnt mean they couldnt sub out portions of the project to other contractors, although my googling for "mcm wireless" entities suggests expertise installing drive-tru related gear. But again, many "mcm" search hits and that could be a completely spurious association with the mcm mentioned in earlier posts.
