How Precious Are Your DWG’s?

Have you ever thought about how precious are your DWG’s in construction? 

What are DWG’s

A DWG file is a drawing created and used by AutoCAD.

Basically it is a file with the .DWG file extension. This denotes it is an AutoCAD file. It stores metadata and 2D or 3D vector image drawings that can be used with CAD programs

This file format is compatible with lots of 3D drawing and CAD programs, which makes it easy to transfer drawings between programs.

Who uses DWG files.

They are often considered the industry standard for technical drawings and blueprints.

Originally named as an abbreviation for the word drawing, it’s a file that contains two and three-dimensional vector graphics. Typically, drafters, architects and engineers use DWG files to develop design sketches.

Our Experience

We have got into a spat with an architect recently because we asked him to issue a dwg file to the Underfloor Heating Contractor.

The architect’s response to the client was:

It is not our policy to provide dwg drawings because:

1. 1. 1. These are accurate only at the design stage and show the intent of what is required.
      2. Buildings change as they are built, if subcontractors use information that may not be correct then this will cause problems later on for you and accountability is unclear.
      3. DWG files can be amended and changes cannot be tracked.  There is therefore an added liability for us that may not be covered under our PII.
      4. It is not normal and has never been normal practice across the industry to issue dwg files to contractors.
      5. They [The Contractor] want the information as it makes their life easier but it increases risk for you [The client]…..this is not in your best interest.

This was the first time that we have come across this response and we were surprised by it.  Have we been lucky to date or is this level of reluctance unusual?

I’d love to hear your views.

Why are we concerned about this?
