Project Management in the Oil and Gas Industry

1.3.7 Execution 
Phase
Now everything is ready for this stage, and this stage involves both qual-
ity assurance and quality control, especially in the reinforced concrete 
works and in the concrete itself composed of many materials such as 
cement, sand and coarse aggregate, water, and additives in addition to 
steel bars. Therefore, it is essential to control the quality of each element 
separately, as well as the whole mixture. In addition to that, the qual-
ity control should follow restrictions during the preparation of wooden 
form, the preparation and installation of steel bars, and pouring and 
curing concrete.
It is clear here that the contractor should have a strong, capable organi-
zation, capable of good quality control, and documents that define the time 
and date in which the work was carried out and who received the materi-
als. At the same time, it’s important to determine the number of samples of 
concrete and define the exact time, date, and result of each test.

How to Manage Oil and Gas Projects 21
Often, during execution some changes occur in the construction draw-
ings of the project as a result of the presence of some of the problems at the 
site during the construction or the presence of some ideas and suggestions 
that can reduce the time of the project.
However, it is important that the change of work be done through docu-
ments in order to manage the changes and build them into the drawings.
The supervisors and the owner must have their special organization. 
The owner organization in most cases has two scenarios:
• The owner will establish an internal team from the organiza-
tion to manage the project; or
• The owner chooses a consultant office to manage the super-
vision on site.
In most cases the design office will do the supervision.
The construction phase shows the contractors the capabilities for local 
and international competition. If, and only if, the concept of quality assur-
ance of the contractor project team is very clear and has experience in a 
comprehensive quality system because the aim of all the competitors on 
the international scene, since the period is working through an integrated 
system, is to confirm the quality of the work and quality control in all stages 
of execution in order to achieve full customer satisfaction.
