Construction

The guidelines for screening the general mechanical contractor and
other associated subcontractors are similar to those for selecting an
engineering contractor. The scope and complexity of the work will
largely dictate the choice of the general contractor. Aside from avail-
ability and quality of skilled crafts, the contractor's safety record and
the dedication of the front-line supervisor to the worker's safety should
be an important factor in choosing a contractor.
Early selection of the general contractor is critical. The general
contractor should be brought in at 30% to 40% engineering completion
to review the drawings and interface with the engineering contractor.
Additionally, early constructibility meetings among the refiner, engineer-
ing contractor, and general mechanical contractor will prove valuable
in avoiding delays and reworks.

Pre-commissioning and Start-up

A successful start-up requires having in place a comprehensive plan
that addresses all aspects of commissioning activities. Elements of such
a plan include:
* Preparation of the operating manual and procedures to reflect
changes associated with the revamp
* Preparation of training manuals for the operator and support groups
« Preparation of a field checklist to inspect critical items prior to
start-up
* Development of a QA/QC certification system to assure that the
installation has complied with the agreed standards and specifications

Post-project Review

Shortly after the start-up and before the general contractor leaves
the site, a meeting should be held among key members of the project
execution team to obtain and document everyone's feedback on what
went right, what went wrong, and what could have been done better.
