Is there any way to be compensated for extra construction costs which were no fault of our own but which were necessitated by conditions that neither the architect nor we could foresee?
Undoubtedly it depends upon the terms of your contract and on the extent to which you can successfully negotiate the reasonableness of your claim. You will be interested to know that there is now a new edition of an American Institute of Architects document that suggests new rules on this and many other contractual matters. It is called General Conditions of the Contract for Construction, Thirteenth Edition, AM Document A201, 1976 Edition. A review appears on page 227. In general it sets forth contract conditions that are much more favorable to contractors than have been common in the past. Every contractor would do well to obtain a copy and study it.
