Al MarafiqProject Location Map
Marafiq IWPP Jubail
One special project is the
Marafiq IWPP project in
Jubail. Marafiq had
developed its coveted IWPP
project in Jubail Industrial
City on a build, own, operate
and transfer (BOT) basis of
apower generation facility
(2,745 MW) and water
desalination (800,000 cubic
meters per day).
This project is the biggest
project of its kind in the
world, fully constructed and
commissioned and is already
servicing the needs of both
the Jubail Industrial City and
the Eastern Province of Saudi
Arabia as a whole.

12. Define the problem
Time delay between the first and second layer concrete
pouring was more than five hours (concrete pour started at 11:30
and the second layer was not poured until 17:30) which should not
exceed above 60-90 min depending on the ambient temperature.
Concrete was found hard in the first layer due to the time delay as it
already started curing.

14. An undesirable discontinuity between layers of concrete that
occurs when one layer of concrete is allowed to harden before the
rest of the concrete is poured in what is meant to be a single, solid
massThe discontinuity occurs between the layers due to the inability
of the freshly poured, wet concrete to intermix with and bind
properly to the hardened concrete. Such a discontinuity is often the
result of logistical issues such as a contractor’s work schedule or an
unexpected material shortage.

17. Ultrasonic Pulse Velocity test requirements by client / consultant
This test is done to assess the quality of concrete by ultrasonic
pulse velocity method by measuring the time of travel of an
ultrasonic pulse passing through the concrete being tested.
Comparatively higher velocity is obtained when concrete quality is
good in terms of density, uniformity, homogeneity etc.

1.Will this completely resolve the problem?
2.Will this only satisfy part of the problem?
3.Will this have little or no impact on the problem?
4.Do we have the authority to implement?
5.Do we have the necessary resources?
6.How long will it take to implement?
Problem Solving (Case Study ) Engr. Khaled M. Al Kolfat4110/15/2014

42. Don't consider any alternative as "perfect solution."
If there were, there probably wouldn't be a problem in the first place
Consider your intuition
or inner feelings in deciding on a course of action
Return to your trusted outsider
Is there something you missed?
Does he/she see a problem with your solution?
Compromise
Consider compromise when you have a full grasp of the problem, and
your alternatives. Competing solutions may yield a hybrid solution.
