17 July 2024:<\/em><\/strong> Why Design for Disassembly?<\/p>\n

The design of a structure to facilitate future changes and dismantlement (in part or whole) for recovery of systems, components, and materials, thus ensuring the structure can be recycled as efficiently as possible at the end of its lifespan.<\/p>\n

In what is thought to be a first in South Africa, Peikko SA has turned precast concrete construction techniques on its head by providing an innovative design for an air plant for the mining project, that combines the advantages of concrete construction with the ability for the concrete elements to be dismantled and reused at a different location on demand.<\/p>\n

\u201cWe were approached by Genet Mineral Processing (Pty) Ltd., the Witbank-based customer who designs, fabricates and erects mineral processing, crushing and screening plants and related equipment for the mining industry, to submit a design for an air handling plant,\u201d states Winston Visser, Project Engineer at Peikko SA.<\/p>\n

\u201cUpon receiving the customer design brief we reviewed further and proposed a sub-frame and superstructure for the air plant; in a precast concrete frame with Peikko bolted connections for easy assembly with the added advantage of dismantlability. This design approach and proposal were value-engineered by the customer engineering team against existing design proposals and other possible design solutions including:<\/p>\n

Structural steel frame (including surface treatment) \u2013 this proposal proved not satisfactory responsive to dynamic loading \/ vibration and overall, more expensive; and<\/p>\n

Cast in-situ on-site option \u2013 this proposal proved to be time-consuming, subjected to high-level health and safety requirements and also more expensive.<\/p>\n

The Peikko SA design proposal was reviewed by third-party independent structural consulting engineers and approved as suitable for this specific project application.\u201d<\/p>\n

\u201cSustainable construction can be divided into two timeframes. In the short term, it\u2019s crucial to minimize emissions related to materials and actual construction, which have an immediate impact. In the long term, the reusability of materials is significant. In this project, we have considered both perspectives as effectively as possible\u201d, states Daniel Petrov, Managing Director at Peikko SA.<\/p>\n

Peikko Approach to Sustainability<\/strong><\/p>\n

\"\"<\/a><\/p>\n

\u201cThe Peikko approach for the customer project specific project application has many advantages for the mining sector,\u201d advised Visser:<\/p>\n

Bolted connections enable dismantlability.<\/strong><\/p>\n

Bolted connections are key to dismantling. The load-bearing precast concrete elements were connected by bolts instead of welding. A bolted connection can be easily opened and closed as long as it remains accessible. \u201cOnce the connection is secured by threads, it can be opened because the grout outside the structural element (e.g. column, beam, etc.) can be lightly chipped away from the connection steel surface, revealing the threaded joint. The structure remains intact and can be easily reassembled\u201d explains Daniel Petrov, Managing Director at Peikko SA.<\/p>\n

\"\"<\/a><\/p>\n

Time and Cost Efficiency<\/strong> – Bolted connections with special built-in components such as anchor bolts, column shoes, beam shoes and hidden corbels (specified and used on this project) were developed by Peikko more than 30 years ago to produce engineered and cost-effective, bending-resistant connections between precast concrete elements. These bolted connections have many competitive advantages, including fast execution, high accuracy due to the lowest tolerances, high fire resistance and high quality<\/p>\n

Air Handling Plant Mock-Up, June 2024<\/strong><\/p>\n

Low-emission materials in focus<\/p>\n

Peikko\u2019s greener option, bolted connections, was a natural choice for the sustainable construction of the mock-up unit given of all the air handling plants scheduled to be constructed in 2024 and beyond.\u00a0 The carbon footprint is 50% less compared to conventional connections allowing for a high environmental rating regardless of this specific or other project applications. Renewable energy was used for the manufacture of Peikko products used for this and other projects. The estimated life span for these mining structures is approximately 20 years. After their required service life, these structures can be dismantled, relocated and reassembled to wherever needed, eliminating unnecessary structure manufacture and thus contributing to CO2 emissions reduction and increasing the environmental sustainability of the structure\u201d says Winston Visser.<\/p>\n
