Mechanical Completion, Hook-Up & Commissioning - Get it done right first time

Every day there are electrical failures of plant, for various reasons. In some cases, the failure could have been avoided; in other cases, it could not be avoided. When a failure occurs, it can result in loss of service, equipment damage or even harm to personnel.  On the assumption that the engineering design is correct, we must strive to ensure the installation, hook up and commissioning are also done correctly. In many cases, extensive equipment damage can result if installation and commissioning are done incorrectly. This adds to a greater repair time and longer loss of service.

Basic Roadmap to Commissioning

1. Develop a Commissioning Plan including a PERT diagram (sequence plan). 
2. Develop a Systemization Procedure
3. Develop and populate the Mechanical Completions and Commissioning Database with System and Subsystem data and respective Inspection and Test Record (ITR) Identifiers.
4. Systemize main electrical drawings, such as one line diagrams
5. Develop / review / revise Mechanical Completion Check Sheets and Inspection and Test Records (ITRs)
6. Develop System and Subsystem folders according to the systemization principles.
7. Host MC and Commissioning meetings to communicate the process to all stakeholders.
8. Develop and maintain Punch Lists, comprising A, B and C punch items.
9. Assemble Mechanical Completion dossiers and MC Acceptance Certificates
10. Assemble Commissioning Completion dossiers and Commissioning Acceptance Certificates
11. Manage the Client Sign off of Final Acceptance Certificates.

​Mechanical Completion refers to the installation and hookup. These tasks are often done by different groups.

Mechanical Completion

We monitor, verify and support:

• Equipment and bulk materials have been installed according to the approved drawings and meet the specifications
• Oversee the work performed by inspectors, to confirm Mechanical Completion Check Sheets are completed correctly
• Review of Punch Lists to verify status of A/B and C punch items are accurate and complete
• Assist in the management of Punch List Register to close all punch items before next phase.
• Support / witness special tests before dressing out cables and hookup

Hook-Up

We monitor, verify and support:

• All hookup work is performed correctly
• All inspections and tests are completed and satisfactory (see above)
• Ensure that the work is ready for the next phase of commissioning

Commissioning

We monitor, verify and support:

• ​Planning of test schedule identifying key activities for temporary equipment and personnel
• Preparation of system for commissioning and management of all notifications including customer/surveyor.
• Logistic support towards and installation of, all temporary equipment required to support commissioning of the system.
• Bringing up systems in a safe and coordinated manner
• Ensuring all documentation is available to record the process and to sign off.
