When acquiring leasehold interests in buildings to be constructed for Federal Government use, Executive agencies must—
    
    
        
        (a) 
         Establish detailed building specifications before agreeing to a contract that will result in the construction of a building;
     
    
        
        (b) 
         Use competitive procedures;
     
    
        
        (c) 
         Inspect every building during construction to ensure that the building complies with the Government's specifications;
     
    
        
        (d) 
         Evaluate every building after completion of construction to determine that the building complies with the Government's specifications; and
     
    
        
        (e) 
         Ensure that any contract that will result in the construction of a building contains provisions permitting the Government to reduce the rent during any period when the building does not comply with the Government's specifications.
