CA shall solicit participation of the appropriate parties and ensure that the tasks are being executed and responsibilities are being met. 2. CA shall report progress of the Cx to the Owner and CM/GC. 3. A/E shall notify CA of all design review or other key meetings relative to the CA's scope of work at least two weeks in advance. B. Sampling 1. The CA develops a sampling strategy, agreed upon by the Cx Team, when multiple identical pieces of non-life-safety or non-critical equipment may be functionally tested. 2. 20% Sampling — 10% Failure Rule will be utilized: a) Randomly test 20% of identical equipment. The first 20% tested, constitute the first sample. b) If 10% of units in the first sample fail, test another 20% of the group. c) If 10% of units in the second sample fail, test all remaining units in group. d) If at any point, frequent failures are occurring, and testing is becoming more troubleshooting than verification, the CA may stop the testing and require the contractor to perform and document a checkout of the remaining units, prior to continuing with testing of the remaining units. C. Communication Protocols Relating to Cx 1. Correspondence shall generally be routed directly between corresponding companies with copies going to all parties of the Cx Team. The primary exception to this is when it relates to a work directive. 2. No communication from the CA shall be interpreted as a work directive.
