Many architectural and engineering departments miss a prime opportunity to utilize CAD by not developing coordination drawings; drawings which are created to prevent costly construction overruns due to clashes in the architectural structure and the equipment layout.
Computer-aided drafters skilled in superimposing or overlaying architectural floor plan with structural, HVAC, MEP building services design and layout plans can determine if an interference exists that would cause field construction re-work.
Before a project enters the construction phase, coordination drawings should be examined for the following:
1.physical conflicts in equipment floor space layouts
2.proper code clearances, especial concerning high voltage equipment
3.correct vertical elevations for routing of duct work and piping
