The systematic process of managing the total performance requirements of a building from design through construction and into handover is at the core of our Commissioning management offering.

From our experience, we know that every construction project is unique with its own precise structures and challenges that must be taken into consideration and, in cases, overcome. We also know there are always unpredicted matters that arise, despite the best planning efforts, particularly during the testing and commissioning phases. Our highly experienced team has worked on commissioning projects around the world and have been successful in solving client’s challenges. What differentiates us in the field of commissioning management in the UK is our collaborative, hands-on, expert-led approach to troubleshooting.

Third-Party Commissioning

AESG specialises in third- party commissioning. When conducted at the start of the project, commissioning is able to considerably lower construction schedules by maximising the constructability of designs and minimisation of punch list items.

Our commissioning engineering team in the UK offer independent commissioning agent services that aim at ensuring during development of a new building, the systems within the building meet the functional requirements of the project in the most cost-effective means throughout the project life cycle. Having successfully worked on numerous projects internationally, AESG have experience in conducting independent commissioning authority services in line with international sustainability and engineering standards. AESG have been able to find major areas for substantial capital and operational cost savings for clients across all the commissioning projects thus far. We work to the highest international standards for building commissioning and follow the guidelines and procedures as per CSA, BCA and ASHRAE.

Handover and Soft-Landing Advisory

Many shortfalls in high-profile, sustainably designed buildings globally have been identified by The Building Services Research and Information Association (BSRIA).

Shortfalls such as excessive energy use and occupant discomfort, which was attributed to a variety of causes, including the following:

  • Users unable to understand how to operate systems that are over-complex
  • The basis of the design from the design team not fully understood by the Contractors
  • Systems not being commissioned properly
  • Information not being passed on or understood correctly due to changes in personnel during the design / construction process
  • Tenants who are not aware of the design basis are making changes to the systems
  • Without the relevant building/ system changes required, changes in occupancy are being made

It was therefore suggested that a ‘soft landings’ approach must be implemented, consisting of the design and construction team involvement, along with the client or end user continuing their involvement for a period of 12–24 months after handover, to make certain that the building operation is in line with the design or that, if required, modifications can be made.

In order to empower the building owner or operator to maintain and update documents as required, there is a contractual requirement to hand over documents that relate to all the materials and equipment that have been installed within a building. This includes Operating and Maintenance Manuals and as-built drawings. These records have usually been given as hard copies, and often are seen to have many deficiencies. Cloud-based software systems can now be used in order to host details and track the submission and approval system and is transparent information-sharing platform for all involved parties.

AESG are involved from the concept design stage to the handover and beyond to facilitate “soft landings”. This allows full control over correct documentation of design, installation and handed over, so that issues are overcome before reaching the commissioning stage and the client receives the correct information on handover.

Building Performance Evaluation

A Building Performance Evaluation (BPE) can be conducted on both newly completed and existing developments, consisting of a whole building assessment to understand the performance gap between the design aspirations and the actual operating performance of a building.

This evaluation considers varied aspects of the asset, covering energy efficiency, occupant health and wellbeing, maintenance, safety and public liability. The results that come from the BPE facilitate review and update of building management policies and procedures, as well as potential retrofit measures, that result in improved performance, increased occupant satisfaction and lower operational costs.

A Post-Occupancy Evaluation (POE) is carried out at the start of any BPE in order to fully assess the existing condition and performance of a building. An evaluation of occupant behavioural patterns, such as hours of occupancy, as well as gaining feedback from the occupants themselves to bring to attention any recurring issues.
