I have to disagree with you, ColCol.
A design is very similar to a software license. Most designers I know retain copyright to their designs. You can restrict copyright to a single use or you can issue a site license.
To answer markac’s questions:
1) A reasonable re-use fee is whatever you can negotiate with your client. The ½ and 1/3 fee would be a good starting point.
2) The re-use fee would be to cover the liability.
3) If you are just negotiating the initial contract simply state clearly what the fees are for re-use of the designs and that you are retaining copyright of the original design.
4) The safeguards are more difficult. Do not let the originals (electronic or paper copies) our of your office. Sign using a coloured pen. Blue works because it’s difficult to photocopy. A disclaimer above the stamp stating that the original is signed in blue and that only the original is a valid representation of the design can be used. You can include a text box in AutoCAD, shrunk to microscopic size that states your copyright. (Put the same text full size as a separate layer with the statement that turning off this layer and using the drawing is an acceptance of the copyright and an agreement to only use the drawing in accordance with the license granted.) This would only be useful in proving that someone used your electronic copies of your documents without your permission. Keep an eye on the client, is he advertising for bids for similar work? If so then take out a set of plans ( either directly or through a friendly contractor) and compare this to your original work. It really comes down to a matter of trust. If you don’t trust your client not to steal from you then you may want to pass on this commission in the first place.
5) Other concerns Where are all these buildings going to be built? Do you have licenses (both professional and business) in all places? How are you going to inspect your designs? Do local codes and practices make the cookie cutter design approach invalid? Is your firm big enough to cover all this work? (it could be geographically diverse)
