9. You are the PM for a high profile, construction project for a new hotel complex in Doha, Qatar. A budget of $475m was agreed at the outset and staged payments set for $75m at the start, $150 at month 3, $225m in month 4 and $25m in month 7 of an 8 month duration. It is now month 7 and an important stakeholder has just submitted a change request which, when you do an initial evaluation, you realize will mean a required scope increase and resultant budget increase of $92m, further resulting in a delayed completion of 3 months. All sellers are in full swing with their production plans and are happy that the project is coming to an end. There have been many challenges during the past 4 months and all of the teams have rallied together in overcoming them. What is the next action you should take?

  1. Hi, please have a check on item no. 12. If we will use this formula “Power gain (dB) = 10×log (RF output power / RF input power)” then the output will be 10dB. Thank you.
