Promenada Shopping Centre in Novi Sad
Promenada is a shopping centre in Novi Sad, Serbia. ADD Projekt worked on its low- and medium-voltage electrical installations: the part of the building services that brings power into the building and distributes it to the loads.
For electrical work, shopping centres are harder than most buildings. Many tenants and shared areas rely on one power supply, and the work has to be coordinated with other contractors on site.
Two roles on one building
As the responsible contractor (odgovorni izvođač radova) for the low- and medium-voltage installations, ADD Projekt answered for carrying out the works in line with the construction design (PZI), regulations and good engineering practice. Under Serbian practice this role is held by a licensed engineer appointed by the contractor. The same engineer keeps the site diary and the construction log and prepares the installations for the technical acceptance inspection.
ADD Projekt also carried out technical supervision on the building, which Serbian regulations call professional supervision (stručni nadzor). The supervisor checks that the works follow the design and the contract, monitors the quality of materials and equipment, and takes part in the technical acceptance of the building.
How LV and MV installation work in a shopping centre usually runs
The order and scope depend on the design and on the construction schedule of the whole building. Work of this kind typically goes through these stages:
- Reviewing the construction design and aligning the schedule with other contractors
- Procuring and checking equipment and materials before installation
- Laying cables and installing switchboards and medium-voltage equipment
- Connecting the low-voltage distribution to the building supply
- Required checks and commissioning of the installations
- Documentation for technical acceptance, including changes for the as-built design (PIO)
Who needs a responsible contractor or supervisor for electrical work
Developers of shopping centres, office and mixed-use buildings, hotels and other buildings with low- and medium-voltage distribution need a licensed responsible contractor or technical supervision that follows the works through to technical acceptance.
ADD Projekt's engineers hold design and contractor licences for low- and medium-voltage power installations and telecommunications networks. The team has more than twenty years of experience.
