How the work is coordinated

Permits cover both the factory package and the site work through the local building department. Denver-metro work is permitted locally. Colorado has no statewide general-contractor license. Cities and counties license general contractors. DORA licenses electrical and plumbing (and similar regulated trades), not general contractors. Autotelic is a municipally licensed Denver general contractor that coordinates licensed specialty trades. Denver building permits run through Community Planning and Development (CPD). Costs are project-specific; no dollar figures.
