Novel pre-cast concrete systems are helping municipalities accelerate the delivery of sports complexes to rural areas of the province.
Since 2015, municipalities in Limpopo have prioritised the delivery of these essential services by overhauling existing and developing new infrastructure.
This strategy is in line with those of the Departments of Education and Sport, as well as Arts and Culture, which is attending to a dire shortage of sport programmes in Limpopo, especially in outlying areas.
Up to 15% of the Municipal Infrastructure Grant has been set aside to develop the necessary infrastructure and support programmes, and Corestruc is playing an important role in helping these municipalities deliver on their mandate.
Using the company’s pre-cast concrete systems, these municipalities are adopting a similar approach to those deployed in the construction of the large stadia for the Soccer World Cup that was hosted in South Africa in 2010.
The use of modular pre-cast concrete items, such as raking beams and seating, played a critical role in helping professional teams accelerate their construction programmes and complete these complex projects under very onerous deadlines.
Manufactured off-site under controlled conditions, Corestruc’s quality pre-cast concrete items are transported to site where they are then lifted and placed into position.
These items can be modified to build grand stands of varying designs and sizes, such as those in the Mopani District Municipality.
Corestruc has already successfully completed two such projects for the Greater Tubatse Municipality, and has just completed its largest stadium for this client body that will be able to seat as many as 5 000 people when it is completed.
“This is the largest such project that we have been involved in to date,” enthuses Corestruc’s Russell Hobbs. “The system comprises just fewer than 700 pre-cast concrete elements and is 126 m in length and 13 m in height at the back rafters.”
Hobbs and other members of Corestruc’s teams have been working alongside the main contractor, PNG Civils, on this project.
These builds are also providing ample work for emerging contractors in line with government’s transformation objectives. This contractor is tasked with completing all brick work associated with the stadium and fitting-out the rooms beneath the structure, over-and-above all the civil-engineering activities relating to the sports facility.
The podiums are the most complex aspect of the construction, and Corestruc’s solution ensures that these structures are completed early, significantly reducing risk of late delivery of the infrastructure.
Hobbs says that Corestruc has maintained impressive production rates on all of its stadium projects – just one of the main reasons for the company’s ongoing growth in this market.
“We have been able to install these structures in as little as eight days, considering that there is no need to erect and dismantle scaffolding and co-ordinate the logistics of incoming construction materials,” he says.
“This has played a major role in opening an entire new market for Corestruc in the province, while convincing municipalities and their professional teams of the many benefits of using our modular systems.”
While speed of the build is a major boon, project teams also benefit from a safer site, considering that Corestruc’s systems restrict the number of people working at heights to its small team of expert installation experts.
These crews comprise seven people, including a foreman and mobile crane operator. They arrive on site after the earthworks and site terracing have been completed by the main contractor to commence casting the bases and installing the connection bolts.
The sites differ in complexity, and Hobbs says one of the challenges on this project were the sunken bases, relying heavily on Corestruc’s expert surveying team to ensure the accurate alignment and placement of the columns.
The heavy back columns were lifted and placed using a 160 ton mobile crane, the largest unit in Corestruc’s large fleet of lifting gear.
Assembly then forged ahead with the placement of the raking beams and seating benches, which receive a grout infill, before the side panels are installed.
A structural steel bracing reinforces the already robust structure comprising concrete elements that are no less than 60 MPa, contributing towards a more robust final product.
This prolongs the overall lifecycle of the structure, while the use of standardised items from the company’s state-of-the-art batching plant reduces the cost of the build.
Hobbs is looking forward to the completion of the sports complex, and yet another successful related project by the Corestruc team!
