<strong>Analysis</strong><br />
Even though the contractor has provided an<br />
updated schedule estimate, it appears that it<br />
is unachievable. The independent<br />
calculation by the customer results in an<br />
estimated duration <strong>of</strong> just under 34 months,<br />
compared to the contractor’s estimate <strong>of</strong> 25<br />
months.<br />
