QUALITY WORKMANSHIP THROUGHOUT A vibrant destination, ideal for families and professionals, Al Khail Gate offers affordable living right in the heart of Dubai. It is a large development, comprising 5664 residential apartments, dictating that when BTU meters had to be retrofitted in all 33 buildings of phase 2, ista Middle East was the contractor of choice. The BTU meter installation work was divided into three schedules: Core cutting works, partial removal of ceilings and BTU meter installation, completed with gypsum ceiling closing and painting works. Each schedule required arranging appointments with tenants in order to obtain access to apartments to carry out the installation works. In the majority of buildings, the chilled water risers are routed through the apartments/units as vertical risers. According to Empower’s guidelines, all meters had to be installed in the corridor areas. It was therefore required to re-route the CHW piping to install the BTU meters in the corridor by bringing the CHW branch pipe from the vertical risers (inside apartment) to the corridor area and to re-connect to the existing fan coil units in each apartment. To achieve this, core-cutting works were carried out to cut holes through concrete walls and the chilled water pipes were taken outside to the corridor area in order

to install BTU meters in the common area. It was a big task to complete the coring works in each apartment with minimum disturbance to tenants, always ensuring no damage to nearby wall paintings and third-party utility services. Because of other services obstructing the work, such as fresh air ducts, ista had to temporarily remove the existing ducts and modify the chilled water lines, before reinstating them to their original position. Once the meter installation was complete, proper insulation was carried out on all the altered portions of the chilled water pipes. With these modifications on existing pipelines, potential air traps, unwanted particles inside pipes and the loss of chemicals had to be considered. As a result, the whole system was flushed completely to remove all unwanted particles and then refilled with the correct amount of chemicals. Chilled water samples were collected and sent to third-party laboratories to verify the chilled water is within operational standards. After the work had been completed, tenants confirmed that they now had better control of their energy bill, paying only for the energy they are using. This allows them to not only save money, but also become more energy aware and help the environment.
