Air Handling Units

Fläkt Woods believe it is providing a unique solution to reducing site logistics costs, by suspending AHU’s above their final position early in the building project.
In what is believed to be a world first, Fläkt Woods has suspended its huge EU AHU units in situ for the duration of the construction project, on a scheme currently being built in South Korea.
When left to the last stages in the construction process, large air handling units often require a great deal of planning to install and interface with other services.
The new complex is known as Samsung Seocho Town, and is located in the centre of newly developed business area of southern Seoul. The hi-tech project will incorporate financial trading areas, insurance and accounting floors, and will become a global centre for Samsung’s financial related business, operating 24hours a day with multinational banks, insurances and funds.
  
The AHUs are lowered into their final position.
Fläkt Woods’ services contract is split in three phases. The first phase, which is approaching €2 million, is for the supply of 75 EU units.
Normally, air handling units are delivered quite late in the construction project. That requires careful planning to get all of the plant room equipment into the correct position in the right order and ensuring smooth interface with other HVAC services.
For the Samsung Seocho Town project, however, the units were delivered early in the project and were suspended above their intended position. At an appropriate time, when plantroom preparation work has been completed the units are simply lowered into position. This method simplifies the logistical planning and significantly reduces site management costs (initial calculations estimate savings of 10%+) as well as guaranteeing 100% quality control, as well as less service engineers and equipment needed for installation.
Protecting the AHU’s needed some careful planning as South Korea is susceptible to heavy rain and typhoons. The team had to analyze the structural integrity of the steel framed building to see if it could withstand the weight during construction, as well as designing protective envelopes to surround the AHU’s.
None of this could have been possible without an extremely close working relationship with Samsung, as MG Choi-project manager for Fläkt Wood’s explained “We have a long standing association with Samsung, and the when we put the idea to suspend the AHU’s we knew it would appeal to them as they are an extremely progressive company. They realized the significant cost and time savings of working this way, and we had to prove to them that it could work.”
