1 7/15/2015 Is there a project labor agreement? No. Davis Bacon Act wage determinations. 7/23/2015

2 7/15/2015 The NPS has a unilateral right to add options, wouldn’t that stretch the schedule?

When the base phase 2A is awarded, the NPS will elect to exercise the 2A options at that time. There are four options under this phase. The NPS may elect between zero to four of these options for this fiscal year 2015 award. The construction time period for the 2A base and any elected 2A options is 365 days.

During this 365 day construction period, NPS may elect to exercise the option of 2B base and any of the seven 2B options. If this option is exercised, the contract will be extended an additional 365 days from the contract completion date of phase 2A and 2A options.

Please Note: any 2A options not elected in fiscal year 2015, may be exercised in fiscal 2016.
