(ii) The department shall: (1) within thirty days of the filing of such order prepare a scope of work necessary to correct the violations and repair the related underlying conditions as are specified in such order; (2) cause repair work to be commenced and expeditiously completed unless there are circumstances beyond the control of the department such as: the inability to obtain access to the building or any part thereof necessary for the making of such repairs in which case the repairs related to the portion of the building to which access could not be obtained may be delayed until access is obtained; or the inability to obtain necessary legal approvals, materials or labor; or there is ongoing litigation with respect to the building that prevents such work from being performed by the department; or the owner undertakes the repair work in a manner that is satisfactory to the department; or commencement or completion of the work is not practicable because a vacate or similar order has been issued by the department or any city agency and/or the cost of performing work necessary for restoring the building pursuant to the order is economically infeasible; and (3) monitor repair work as it is performed in accordance with subdivision m of this section. For the purposes of this subdivision, "economically infeasible" shall mean a determination by the department that the cost of repairing a particular building exceeds the anticipated market value of such building after all repairs have been completed. However, any determination by the department that, for the purposes of this subdivision, repairs to a particular building would be economically infeasible for the department to undertake, shall not take into consideration the owner's conduct with respect to the building.
