About us - PM Group
Design co-ordination played an important role in the successful completion of the building permit design and detailed design for the Toms Group state-of- the-art confectionery facility in Poland.
This type of complex, process driven design project required significant design co-ordination especially between the various engineering disciplines and the process and utility contractors. PM Group developed and managed the 3D BIM model in Revit for all disciplines, the specialist contractors and equipment vendors to input/access through the design process.
The building permit design was prepared in accordance with the Polish Codes by licensed designers, and was comprised of the following disciplines:
The main building structure was prefabricated. The foundations were cast -in situ and the prefabricated steel trusses brought to site.
The main building consists of:
The HVAC system provides the production and office areas with treated air via dedicated supply and exhaust units. The process equipment generates large internal heat gains. The volume of air moving through the various process areas exceeds 340 000 m3/h. The heating system is generated from the Central Utilities Building. External chillers provide the chilled water to the requirements of the various HVAC systems. There is also a 5,000 sq m chilled warehouse, for storing finished product at 15°C. A central Building Management System (BMS) controls the entire plant.
Ensuring continuity of supply
During finalisation of the purchase contract there was no power available within a radius of 4 km. A new power line needed to be constructed and a new 5MW power station now supplies the site from the city. The main incoming electrical switchgear is housed in the Central Utilities Building (CUB) from where it is stepped down to working voltages and distributed around the site.
Electrical installation included:
A standby generator guarantees supply to the fire protection system and to the semi-finished warehouse. This is critical to maintain product temperatures at 15°C for up to 24 hours in the event of an interruption to the mains power supply.
Utility generation is housed in a standalone CUB, connected via a pipe bridge to the production building. Three different hot water systems (80, 55 and 40°C) are required for the process. Process wastewater and domestic sewage feed to the waste water treatment plant.
Fire hydrants are located around the periphery of the site and sprinklers installed in the raw material warehouse.
