
The aim of this series of presentation is to give guidelines for the effective supervision of
a pipeline construction Project.

We will try to convey DESFA’ s experience in such projects both as Owner and as direct
labor supervisor on its own projects.

With the start of the Construction phase of a Project, just after the Contractor
nomination, the definition of a Supervision Body is mandatory by Law.

Supervisors are placed permanently on site to implement and execute the
Project effectively and in line with the requirements of the Construction
Contract, the Legislation and the Good Engineering practice.
3

Supervision provide Confirmation to the Owner that the Works are progressing
correctly and is responsible for making recommendation to the Owner for the
take-over of the Works.

Supervisors have the responsibility to reject any aspect of the Works which are
affected by a deviation / non Conformance.

The choice of Supervision Body can be done either by direct assignment of an
expert brand or by tender procedure.

For both uses the activities, obligations and responsibilities of the Supervision
shall be defined analytically. Here after we’ l proceed on a description of this
“SCOPE OF SERVICES”.

The SUPERVISING ENGINEER shall:

Review and comment the CONTRACTOR’s breakdown of the Works. The breakdown will be
used for the CONTRACTOR’s quality plans, for progress reporting and for recording completed
elements of the Works. Confirm that the scope of work is fully covered.

Review the technical adequacy of the CONTRACTOR’s plans, procedures and method
statements. Check that the scope of the Works is covered and the requirements of the Technical
Data of the CONTRACT are incorporated. Such plans shall include quality plans and safety
plans. Check that the CONTRACTOR’s proposed list of (future) plans and procedures is
adequate.
5

Check that adequate plans, procedures and method statements exist prior to activities
performance and check that such plans and procedures are followed on a daily basis. Produce
supervision plans and reporting to match CONTRACTOR’s activities.
