Schedule Narrative
General Assumption/Basis
Jakarta and Seoul Engineering workhours is based on 5-day week , 10-
hour day
Site workhours is based on 6-day week, 10-hour day
Non-effective days is based Indonesian National Calendars for days
classified as national holidays
Efficiency during fasting month of Ramadhan is taken as 60% of normal
efficiency
Indonesian “normal” weather pattern is considered with month of
September to February is considered as rainy season where efficiency is
taken as 85% of normal efficiency

Schedule Narrative
Construction Assumption/Basis
Subcontracting definition from Subcontracting Plan
Schedule basis derived from “Manual” Construction Level-2 schedule
developed by Construction Department
Further detailing and sequencing, including area classification definition,
is executed by Construction Department
Manhours is estimated from tender BQ estimates using in-house
Mhr/BQ unit rate
First review of schedule forecast is expected to be conducted in Q2 2012
where more accurate BQ is available (later update of baseline changes
will only be done if there is significant changes in scope/BQs/outsideimpacts which is to be agreed with COMPANY)
S-curve and Histogram is based on P6

Schedule Narrative
Commissioning Assumption/Basis
Split of work between Construction and Commissioning as per Exhibit-C,
Appendix J
Samsung Completion Management System (CMS) will be used to
administer system completion activity which will monitor progressed
based on count only
Commissioning item weighting is based on manhours
S-curve and Histogram are based on P6
