The importance of Mechanical Completion and Turnover Packages.
We are all familiar with Project Management as the overall umbrella for Engineering Management, Procurement Management, and Construction Management, to achieve a well-orchestrated project. But along the line, there are always challenges that are not obvious from the onset, and consequently slip through the safety net, resulting in some level of under-performance.
Today, I want to focus on “Mechanical Completion & Turnover”. At some point in construction, it will be necessary to turnover that work to the client and to receive the client’s acceptance. This is a key task, since if there are problems later on, it would be likely be more difficult to address the issue. Take structural foundations for example. How would it be possible to address any remedial work or inspections of foundations if they are buried? Yes, we have all the required quality forms signed off, but has that phase been signed off by the responsible person? If not, then there may be room for conflict.
The solution, is to prepare Mechanical Completion (MC) Package (or Dossier), with all the necessary forms and drawings, that will allow a systematic turnover of the project work.
1. Documentation for a MC Package:The MC package shall consist of:
Defining the boundary limits for medium size projects is generally approached at a discipline level, and a further breakdown at system and perhaps sub-system level, such that the defined boundary is autonomous and can be handled as a manageable work pack.
Examples of electrical sub-systems might be:
Two diagrams belonging to a package of drawings are shown below for example. The layout diagram indicates the physical boundary limits of equipment within the E-House / packaged sub station, while the other one diagram provides the functional boundary limits. Each subsystem is then assigned a turnover number.
In my next post, I will discuss how engineering workflow methods that support Mechanical Completion.

1. Documentation for a MC Package:The MC package shall consist of:
- A Mechanical Completion Certificate (MCC)
- The Check Records (CR)
- A Punch List Register (PLR)
- A MC Status Index (MCSI)
- Carry Over Work Register (COWR)
- Mechanical
- Electrical
- Instrument/Telecommunication
- Piping
- HVAC
- Safety
- Mechanical completion of non-operational systems
- Structural
- Surface protection, Insulation and Fire proofing
- Architectural
Defining the boundary limits for medium size projects is generally approached at a discipline level, and a further breakdown at system and perhaps sub-system level, such that the defined boundary is autonomous and can be handled as a manageable work pack.
Examples of electrical sub-systems might be:
- Power Distribution Transformer, with associated cables and control equipment
- Main switchboard bus system, with associated cables and control equipment
- Individual feeders to (for example) VFD, motor and associated cables and control equipment.
