Project Overview

The Mpumalanga International Fresh Produce Market is perfectly located within the luscious Lowveld as
catalyst to stimulate growth in the agricultural sector, create a significant number of job opportunities,
create scope for the establishment of downstream business and act as an important tool to fight food
insecurity.
The design of this modern facility addresses the needs of the modern food industry and is designed to
operate more effectively and efficiently than existing, traditional fresh produce markets. The entire
project consists of 17 buildings; each playing an integral part of the market operations. In order to achieve
the design requirements, improvements were made to the physical infrastructure layout, the building
structures and in turn affecting the operations and management of this ‘market of the future’.

Project Details
From the very outset it was realised that to manufacture a roof of this size with the Main Structural members being 3,6m toblerone trusses of welded construction and then deliver them to Nelspruit was going to be an extremely expensive transport exercise and would not make economic sense and thus the decision to make the entire structure piece smal
The required climatic conditions within the completed building envelope dictated the roofing system to be used comprising a two layer sandwich configuration of 0,47 Widedek ceiling sheets , a 135mm Starlite Insulation blanket and 0,53 SAFLOK external weather sheeting. The roof is split into three equal segments for sheeting separated by gutters
The main challenge on this Project was the shear size of the roof structure and it’s structural framing system requiring a major consideration of how to transport it to the site 330 km’s away from the fabrication shop. This was overcome by detailing it as piece small allowing the transport loads to be maximised which then added further challenges as to how to fabricate it like a meccano set while ensuring all the pieces went together seamlessly. These challenges were overcome by careful consideration of the jigging systems that would be used for the fabrication of the components and then trial assembling the major structural components and interfaces between them.
Benefits of Steel in this Application

Structural Steel is the only construction material that could have been used to achieve such large scale open spaces under roof that were integral to the Architects vision for this development.
8 No internal columns for a 30,000m2 roof coverage is unprecedented.

With its high strength to weight characteristics and the ability to assemble such light weight elements of steel in a structural configuration that would enable such large span structures to be designed, makes it the ideal material.

The use of tubular sections further enhances the visual appeal of the roof structure let alone them being the most structurally competent sections.
