has been carried out. The MC certificates shall be used per MC
package.
Mechanical Completion
Check Record (MCCR)

Mechanical Completion (MC) The checking and testing of equipment and construction to confirm
that the installation is in accordance with drawings and
specifications and ready for commissioning in a safe manner and in
compliance with project requirements.

Commissioning & Commissioning
Mechanical Completion (CMS)
Mechanical Completion is an integral process of management verification of approved design
installation. It represents the interface between construction and commissioning group activities and
includes all interface checks between all systems and subsystems whether modular or plant wide.
Mechanical Completion verification confirms that construction and installation of equipment, piping,
instrumentation, cabling, electrical, telecoms and mechanical components are physically complete
and all inspections, testing and documentation requirements have been completed.
Preservation
Preservation covers the method of protection and preventative maintenance carried out on equipment
and systems before and after they are taken into use. The process begins with the application of
preservatives and protection fittings by suppliers/vendors, prior to delivery permitting the
equipment/system to arrive at GPS fabrication yard undamaged.
Pre-Commissioning
Pre-Commissioning (PC) is the stage that involves the verification of functional operability of
elements within the system, by subjecting them to a set of simulated operational conditions, to
achieve a state of readiness for commissioning. Pre-commissioning requires energisation of
equipment and the introduction of the Permit to Work / LOTO systems.

2. Some examples include the running and entire testing of the power generation systems, testing of
emergency shutdown and control systems and dynamic trials on oil and gas export systems prior to
load out to minimize the offshore or site scope.
Commissioning
GPS’s commissioning capability consists of checking and testing all functions according to their
design parameters in conditions as close as possible to the design conditions, and in bringing them to
the status “Ready for Start-Up / Operations Readiness”.
Start-Up & Commissioning
Late facility design details, accelerated construction schedules, just-
in-time manufacturing of equipment and managed low-levels of
materials inventory at the distributor are the New Normal. As such,
improper attention to systems completion, systems turnover, pre-
commissioning, commissioning and start-up can lead a project further
toward failed economics.
Useful Definitions:
System – A section of the facility or process which is mechanically
continuous, but which can be isolated from other sections of the plant
or process in a way which allows independent turnover, inspection or
confirmation of process function.
Pre-Commissioning – Checking for design conformance, piping
mechanical completion, electrical code compliance and instrumentation installation and process tubing
adequacy. Pre-Commissioning includes equipment run-in, PLC and DCS action checks, and a rotation
check of process equipment which can be isolated from the overall process. Pre-Commissioning
activities overlap with construction activities. The two are isolated from one-another by system
boundaries and a robust system package turnover protocol. LOTO compliance, always a must, takes on
even greater meaning as electrical equipment and circuits become energized and equipment rotation
inspections commence.
Commissioning – The phase of a project where actual process fluids are introduced to process
equipment. Commissioning includes multiple function and process performance checks but precedes
actual Start-Up.
Start-Up – When stable process conditions are established and intentional product making or
manufacturing for sale commences.
As one of the last contractors to have access to the work, Ardent
inherits the lost schedule float of all construction predecessors in the
form of construction acceleration. To help manage ourselves toward
timely and efficient completion we have developed a number of

3. proprietary databases and work-order progress management tools. These tools blend well with systems
turnover and follow on well into systems pre-commissioning and start-up.
Pre-Commissioning starts when facility systems achieve Mechanical Completion. In today's fast track
world of building while some detailed designs are still in review, the Pre-Commissioning efforts must be
tasked and managed in conjunction with the project's integrated Critical Path schedule. Construction is
often progressed by area, and by the time erection progress exceeds 70% and/or I&E progress exceeds
50%, it is time to begin turning over systems from construction to the Pre-Commissioning team. Ardent's
system turnover database and protocol helps to define,punchlist and manage inspection and pre-
commissioning efforts. Our experienced instrument technicians and field process techs can inspect,
track and assure systems completion progress is monitored, measured, achieved and reported.
Commissioning and Start-up are a key part of project execution and are the natural outflow of quality
systems completion, turnover and pre-commissioning. Introducing and stabilizing process fluids and
conditions and commencing product export are WHY facilities get built. Ardent's Pre-Commissioning,
Commissioning and Start-up Techs can help lead the way to the ultimate finish line, successful project
completion.
5 MECHANICAL COMPLETION
5.1 Introduction
This chapter forms the basis for the execution and documentation of mechanical completion
activities.
Mechanical completion takes place through all phases of a project, up to the commissioning phase.
• Mechanical completion encompasses all disciplines.
• The detailed responsibilities are described in the contract.
• Executor of MC activities is responsible for establishing and compiling the MC dossiers and
report status into PCS.
5.2 Documentation for a MC Package
The MC package shall consist of an MCC, an MCSI, MCCRs and a PLR printout as described
below.
A Mechanical Completion Certificate (MCC) is a form completed by the Executor after all MC is
carried out. The MCC is the cover sheet for each MC package. An MC package shall when signed,
be ready for handover to commissioning.
The Check Records (MCCR) are the forms on which the Executors record the results of all
checks, inspections and tests carried out for each individual item.
A Punch List (PL) shall be prepared by the Executor along with the package a PL shall be included to
document incomplete work.
A Mechanical Completion Status Index (MCSI) listing the status of all MCCRs for the MC
package shall be included.
5.3 Handover at Mechanical completion
Handover from Mechanical completion to commissioning shall be at commissioning package level,

4. documented by the ready for commissioning certificate (RFCC).
5.4 Carry Over Work Register (COWR)
The COWR lists all punch items that the Project accepts as cannot be completed during present
phase. The register is used for the release of the work from the Executor and will as such be an input
to the scheduling and planning of outstanding work to be performed during later phases.
The COWR Item number and cross reference to the Punch list/MCCR shall be given. COWR work
shall be marked up on drawings or sketches and be included in the records.
Material Status List (MSL) and marked up drawings/instruction shall contain sufficient information
for job setting in a later phase.
