Any new construction project, home addition or major remodelling project will require technical drawings for a few reasons. Firstly, to pull any type of construction permit from the municipality, a technical drawing that conforms to todays norms is a must. Also the technical drawing is what will allow the contractor to properly price the project when you are in the estimation phase. Last, the plans are used to communicate exactly what type of work needs to be done for all the contractors that are involved. It is clear to see how vital proper plans are when it comes to a construction project.
