SAPMT has reviewed the subject submittal dated October 22, 2014 and has no objection with the following comments:
1.	Water curing has to continue until 70% of the specified compressive strength is reached, but not less than 7 days.
2.	While it is preferred that precast panels are transported after the required strength is verified by tests, nevertheless, based on the above, transporting the precast elements after curing is acceptable after 7 days, as confirmed by subcontractor calculations that panels can support lifting and transportation loads plus any other loads as per the PCI handbook and also as concurred by the project designer.
3.	It is advisable to conduct a few closely monitored trials and observe for any cracks, spalls or deformities before adopting the practice.
4.	It is Contractor’s responsibility to remove any panels which do not meet applicable standard requirements or aesthetics necessary for the wall, and replace with new ones, if and when rejected by Saudi Aramco.
5.	IC shall ensure that no scope change or cost/ schedule implication arises from this letter.
Should you have any questions, please contact Sohail Moughal, Project Engineer at 012 422-4570.
