DEFINITION OF SUBSTANTIAL COMPLETION - The Date of Substantial Completion is 
the date certified by the Architect when construction is sufficiently complete, 
in accordance with the requirements of the Contract, so the Owner can occupy or 
utilize the Project for the use for which it is intended, as expressed in the 
Contract. Unless otherwise provided in the Contract, the Date of Substantial 
Completion is the date on which the Project warranty commences.

WORK REMAINING TO BE COMPLETED - A list of items to be completed (the 
'punchlist') is attached hereto. Owner and Design/Builder acknowledge that 
this Work is incomplete and that Design/Builder will diligently work to 
complete it as soon as possible. The failure to include any uncompleted items 
or defective Work on the attached punchlist shall in no way alter the 
responsibility of the Design/Builder to complete all Work in accordance with 
the requirements of the Contract.

OWNER RESPONSIBILITIES - Unless provided otherwise in the Contract, the Owner 
will assume responsibility for the following items as of the Date of 
Substantial Completion:

     1.   All property and casualty insurance for the Project.
     2.   Security for the Project.
     3.   All permanent utilities (electricity, gas, water, sewer,
          telephone, etc.)
     4.   Operation and maintenance of the Project.
