A new distribution warehouse is being constructed for Builder’s Warehouse.  The site is next to the Gautrain Railway.  One of the Gautrain trains derailed in a freak accident and caused damage to the works.  The Contractor had to repair the damage to the works which caused a delay of 2 (two) weeks in the completion of the works.  This had a severe effect on the programme and of reaching practical completion at the due date. 
 
You are the appointed Contractor.  Explain and motivate whether you would have a claim for the revision of the date for practical completion in terms of the JBCC PBA 6.2.
