Below is a small selection of the many civil and structural projects previously undertaken by Carlisle & Associates.
STRUCTURES
ALPLA LANSERIA PLANT
Client: Griffin Holdings
Completed: 2024
Alpla, an international leader in plastic packaging and recycling solutions, required the development of a new state-of-the-art manufacturing facility and warehouse in Johannesburg. Carlisle & Associates Consulting Engineers were appointed to undertake the structural engineering design for the project.
The initial phase, completed in 2022, comprised approximately 36,000 m² under roof. A subsequent expansion in 2024 added a further 10,000 m², resulting in a substantial and highly impressive industrial facility.
Key components: Structural steel roof, reinforced concrete columns and slabs, tilt-up panels, piled and pad footing foundations, solar panels on roof.
ALPLA BALLITO RECYCLING PLANT
Client: ALPLA
Completed: 2025
Alpla opened a PET recycling plant in Ballito in 2025. Carlisle & Associates were appointed to undertake the civil and structural engineering design for the project.
Approximately R1 billion was invested in the facility, which comprises 12,000 m² under roof space and extensive outdoor storage areas. The project included unique Geotechnical challenges, which will be highlighted in the ‘Civils’ section below.
Key components: Structural steel roof, reinforced concrete columns and slabs, tilt-up panels, piled foundations, solar panels on roof.
MANDALAY RESIDENTIAL COMPLEX
Client: Summercon
Completed: 2025
Mandalay is a housing estate situated in Beverley and is typical of the many residential estates that we have designed for this client and many others. Carlisle & Associates provided the civil and structural engineering services.
Key components: Raft foundations, masonry building frame, precast floor slabs, timber roofing, stormwater management.
AMPLATS MINE
Client: Savannah Metallurgical Systems
Completed: 2018
Carlisle & Associates were responsible for the design of a thickener bridge and rake arms for a mine in Limpopo, South Africa. We have been involved in the design of many auxiliary structures for mines within the country, Africa and Russia.
Key components: Structural steel bridge and rake arms

CIVILS
ALPLA BALLITO RECYCLING PLANT
Client: Alpla
Completed: 2024
The subsurface soils in the location of this coastal site were such that a layer of weathered sandstone restricted the downward drainage of water within the alluvium layer above, creating a ‘water-bed’ effect. These conditions affected the bearing capacity, foundation stiffness and settlement performance which are critical factors in foundation design. Carlisle & Associates worked with Kaytech to improve the founding conditions and thereby ensure a robust and reliable design.
Key components: Excess pore pressure, water-bed, localised perched water tables
