Timing/documentation: The evaluations will take place at two points in time: at the
end of the FEL, to ensure the completeness and the quality of the design; and at the
end of the project after start-up and the capacity run. A final evaluation report must
be prepared for all involved disciplines.

Summary
The opportunities for the process industry are to improve the quality and efficiency
of process plants and the design process

. The design process need to be based on a well developed work process, which
is based on feed forward actions with limited feed back (reviews) adjustments
and includes front end loading (a completed process design package) before
detailed engineering starts. Such an approach allows concurrent engineering
with considerable time and efficiency savings and with as target no rework.

The quality of the process plant is achieved by application of value improvement
practices (VIPs) during the work process.

. The VIPs described shortly and considered crucial for a quality design are;
technology selection, waste minimization, process simplification, process/
energy optimization, design to capacity, maintenance, value engineering and
construction.
. The VIPs have to be applied during the design process, an overall time line
was presented for implementation during design and engineering.

Appendix 10.1
Step Description of Preliminary Plot Plan and Lay-out (Example)

Description: The development of a preliminary plot plan and lay-out and a con-
densed form of the three- dimensional model with the major equipment and civil
provisions. Provisions for future expansions supported by the business should be
included.

Input:
Process information
. Index flowsheets, process flowsheets, equipment list, major equipment
descriptions and dimensions, significant elevations.
. Logistic information as: (un)loading and storage requirements.
. Site and block drawings with neighbouring activities as; outside the fence
activities, other plants, OSBL emergency and utility provisions, soil character-
istics, loading facilities.
