Response #2:
1) Attention is directed to the Geotechnical Design Report in the Information Handout suggesting that the settlement period should be 6 months. The settlement period is dependent on the settlement rate, which is not to exceed 1 year, see sheet 32 of 169 of the plans. If settlement is reached prior to this time, and authorized by the Engineer, the settlement period may end sooner.

2) During the settlement period, when no work is to be done, working days will not be charged. Attention is directed to the Geotechnical Design Report in the Information Handout, Construction Considerations #12, "During the settlement period, large equipment and/or heavy loads shall not be stored on the embankment, which could cause differential settlement."
