Case Study - Office Block at 20 Farringdon Road, London, EC1M

20 Farringdon Road

In 2015 we were contacted by Flatt Consulting, who requested a survey and detailed report illustrating the present condition of the Air Handling Units at above site. Based on the nature and complexity of the job we proposed that the units were to be overhauled instead of replacing them with new. To replace all 7 units would have cost approximately £375,000 including site work. The project featured internal and external units.

Our Proposed Solution and Benefits

Following on from our inspection, we offered the following:

We have refurbished the units and carried out the above work during nights (out of hours) for less than a quarter of the price of the proposed new units.
