Detailed Engineering

In the detailed engineering stage, the mechanical design of various
components is finalized so that the equipment can be procured from
the qualified vendors and the field contractor can install it. In preparing
construction-issue drawings, the designer should pay special attention
to avoiding field interference and allowing sufficient clearance for
safety, operability, and maintainability.
To ensure project-related safety, health, and environmental issues
have been identified and resolved, the refiner should have in effect
a process safety program that confirms the project complies with
OSHA requirements.
Procurement of materials in a timely fashion is a necessary part of
detailed engineering. Successful procurement requires:
• Early involvement of the procurement team
» Identification of long-lead and critical items
• Identification of "approved" vendors
• Identification of appropriate specification standards
• Competitive bid evaluation based on quality, availability, and price
• Establishment of a quality control program to cover fabrication
inspection
« Establishment of an expediting system to avoid unnecessary delays

Pre-construction

Activities performed in the pre-construction or pre-turnaround
stage are essential to the success of the project. Some of the key
activities are:

• Finalizing the project strategy plan
• Determining required staffing
• Identifying lay-down needs and securing specific areas
• Performing the detailed constructibility study
• Identifying additional resources, such as special equipment or
special skills
