The temporary electric service attached to the existing house will be removed by the College prior to demolition. 3. The construction fencing around the perimeter of the house- how close can we put this fence to the property on the left? Will it be required to have fabric installed? Locate construction fencing minimum ten feet from existing structures to remain. Chain link fencing shall be in accordance with CWM Special Provisions listed in Appendix Y of the Project Manual. 4. The shrubs to the left of the house, can these be removed (and not replaced) so the machinery can use this area to set up?
