Testing and Commissioning

Testing and Commissioning is a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria. It is an all-inclusive process consisting:
Successful commissioning of a project results in ‘critical systems’ resilience, maximum energy efficiency, indoor environmental quality, extended systems life and reduced operation and maintenance costs. Commissioning ensures a new facility begins its life cycle at optimal productivity with all systems operating as intended.
The program shall be submitted to the Project Manager and Engineering Team Clerk of Works for review.

Testing & Commissioning Processes

Commissioning Process: a quality focused process for enhancing the delivery of a project. The process focuses upon verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner’s Project Requirements.

With the increasing complexity of modern buildings, and particularly the integration of lighting and other controls, commissioning is becoming even more important and valuable. Commissioning is an added cost to the initial project. Commissioning reduces the initial occupancy costs and disruptions as well as reducing ongoing utility costs. For some clients, minimizing occupant dissatisfaction can be more valuable than accountable financial savings, so the cost is secondary. Unfortunately, the initial cost and ongoing costs are separately accounted for in many organizations and it can be difficult to convince the client of the value of commissioning. The financial benefits are well documented in *The Cost-Effectiveness of Commercial-Buildings Commissioning,* a cost-effectiveness study of over 200 commercial buildings, by the Lawrence Berkeley National Laboratory. They found the savings often paid for the commissioning in the first year.

Manufacturers update their software to deal with errors and also to make significant performance changes. Some designers require that the installer installs any software updates as they become available during the warranty period. This is good in that the client has the latest version, but it can have some unexpected consequences. On one project the load shedding software was changed, so the update did not run the load shedding correctly. The installer and client did not realize the change until the next electrical bill was more than double what it would have been if the load shedding had continued. In another case, the historical data collection software was changed and the history became inaccessible. Be careful, a good working system is not necessarily better having updated software installed.

Many specifications include a provision that the manufacturer continue to have replacement components available for five years from completion. This warranty requirement does not necessarily include the replacement, only that they are available. Since there is no financial provision in the contract for this requirement, it is difficult to enforce unless the contract is covered by a performance bond. A performance bond is issued by an insurance company, typically, to guarantee the completion of a project but it may also be required to cover the extended warranty period.

Process commissioning can begin after precommissioning tests are complete and all identified issues are corrected. Plant equipment is placed into normal operation during this phase.

Process commissioning should not commence until the final checklist is reviewed and verified. This list will include:

Testing and commissioning is to be carried out on installations to ensure that they are safe and meet the design requirements. The witnessing of tests on and off site shall be defined by: Design specifications – Mechanical and Electrical. Requirements of the validation process. The test data are provided as records for future maintenance and service work

The stages are presented in the normal flow in which they are executed; however, many separate activities across all aspects runs concurrently. Some of them are: factory acceptance testing and modular construction, check construction and quality of build, tracking progress and system status, cleaning procedures and drying, pre-commissioning procedures, vessel check sheets, and instrument loop, electrical, and control system testing. The first stage—factory acceptance testing—the final check performed on vessels and major equipment prior to delivery to the job site. Here the emphasis for the commissioning team is not on the design and fabrication of the unit, but more on its cleanliness, the test installation of major components, and suitability of the equipment to travel. Sending commissioning team personnel to factory acceptance tests can fall foul of project budgets, but this strategy must be challenged by the commissioning manager. checking construction and quality of build, , as construction activities commence, start to be installed and major piping runs established, it is advisable for the commissioning team to start making regular site visits to closely monitor and follow the build progress. It is always easier, quicker, and cheaper to correct any installation issues at early stage rather than rectifying it later.

The testing is normally undertaken to prove the quality and workmanship of the installation. Such work is undertaken before a certificate is issued to ‘enliven’ (i.e. to make live) services whether electrically or otherwise.

Upon completion of the commissioning, performance testing can begin. Some may not distinguish between commissioning and performance testing. However, for programming purposes it is worth distinguishing between commissioning plant as individual systems and undertaking tests of all plant systems together, known as performance testing, (and including environmental testing).
Sometimes this performance testing is undertaken once the client has occupied the facility, e.g. for the first year because systems are dependent upon different weather conditions. In such cases, arrangements for contractor access after handover to fine-tune the services in response to changing demands must be made.

However, for some facilities it may be necessary to simulate the various conditions expected to prove that the plant systems and controls operate prior to handover, e.g. computer rooms

TESTING AND COMMISSIONING

Commissioning is a quality-oriented program that applies in-depth building and engineering knowledge to minimize risk and ensure efficient operation of building throughout its lifecycle.

Commissioning is the most critical aspect of the development cycle as it ensures that a building is handed over to operate safely, efficiently, and in accordance with how the owner intended. Susnomics follows CIBSE and ASHRAE standards for commissioning and our team of experienced engineers & commissioning managers provide assurance to clients that their building will operate as they intended.

Susnomics Cx services include:

New Building Commissioning: For New building commissioning we ensure quality design, construction and also verify design goals for the building are accomplished.

Retro-Commissioning: Existing Building Commissioning: The Existing Building Commissioning assists the building systems perform interactively to meet the Current Facility Requirements and provides the tools to support the continuous improvement of system performance.

Green Building Commissioning: Fundamental and Enhanced LEED Commissioning & commissioning for other Green Building rating systems (ESTIDAMA, BREEAM etc.). We also work in concert with Measurement & Verification, suggest the strategies to monitor the energy consumptions and savings.

The Commissioning Process

The Commissioning Process includes specific tasks to be conducted during each phase in order to verify that design, construction, and training meet the Owner’s Project Requirements.

Design Phase

1. Document building owner’s project requirements and design intent

2. Prepare detailed commissioning plan and responsibilities

3. Review all service-related documents and drawings.

Construction Phase

1.  Prepare required test forms, scheduling forms, and process management forms

2. Regular Monitoring and reporting on the process

3. Assist with installation verification

Performance Testing

1. Monitor all contractors’ testing work

2. Verify contractors’ performance testing

3. Conduct independent third-party performance testing to verify that building systems provide design intent performance

As built Documentation and Training

1. Review O&M manuals

2. Prepare systems operating manual

3. Review as-built documentation

4. Coordinate contractor training

5. Conduct systems operations training
