Johnston Sweeper

JPG were appointed as consulting civil and structural engineer by Johnston Sweeper, who manufacture road sweepers for the domestic and export market, for their new assembly plant .

The proposal was to construct two large buildings, namely Building 9 and Building 10, to enhance their existing manufacturing facilities.

Phase 1 of the development was to construct Building 9 comprising of 5,000m2 manufacturing space capable of accommodating six overhead cranes and jib cranes mounted anywhere on the production floor along the assembly lines. Within the building there would also be 1,999m2 of office space spread over two floors and an undercroft for 76 car parking spaces.

The structural arrangement was carefully co-ordinated with the client’s parking requirements to provide the maximum number of spaces. Balancing the impact of the cost of the superstructure against the maximisation of the spaces was crucial to the viability of the project. The introduction of a one-way system for the movement of the vehicles with one-way entry and exit helped to achieve this. Three sides of the car park are open to the elements allowing natural ventilation to take place
