MacEdwards House Extension

Finding himself pressed for time, Dr S. Albanis from AIS-CE Consulting Engineers, the Engineer of Project Mc Edward’s-House Extension in Midrand Kyalami, evaluated alternative options for a flooring system, i.e. reinforced / prestressed / prefabricated or in-situ concrete.

The main requirements he considered to tackle the looming December crunch in the construction industry, where

  • Structural performance to meet the load criteria
  • Speed of construction / erection
  • Avoid “hidden” later unavoidable time-consuming activities such as screed, structural topping, ceiling, etc.
  • Aesthetics of the final product

At a meeting with Aura Entle, the Deep Flute Floor System was presented to the Engineer.

Aura Entle was delighted upon the announcement by Dr. S. Albanis that the Deep Flute Floor System was selected amongst all other candidate alternatives as it was satisfying the stringent criteria for the assessment.

The Deep Flute Floor System is a floor system characterized by its steel permanent formwork. The steel acts alone to carry the construction loads – without any support within its span.The steel formwork also serves as the mould giving the concrete the shape required of it to act as part of the Engineered floor system.

Significantly less concrete is required in the Deep Flute Floor System – than traditional floor systems -thanks to the steel. As a result, a Deep Flute floor is much lighter than other floors. The Engineer was well pleased with the system as it meant he would not have to redesign his existing walls and foundations to carry additional loads from the slab.

The Deep Flute Floor System does not require the use of any cranes in order to be deployed, and even then the team at Aura Entle was confident that they would deliver the completed 100 square meter floor in under three and a half days of site work.

The folds of steel on the underside of the floor create spacious cavities where services can be placed. The cavities are intentionally kept clear of concrete thus making the services carried out asaccessible for future maintenance and upgrades. Yet another benefit to the Client. The electrician and plumber made use of these spaces to neatly hide away their wires and pipes in the floor.

Finally, armed with the knowledge that the Deep Flute Floor System would not require any props, the Project Engineer saw an opportunity to realize more savings in time, hassle and money. This he would accomplish by taking full advantage of the space available to him on the ground floor – the space that would be free of props. The preparations of the ground slab were run simultaneously with those of the 1st floor slab with the aim of pouring both slabs at the same time. The Engineer’s plan was carried out successfully.

The advantages of the steel formwork floor solution stretched beyond the construction phase. Even though it rained, the kitchen, on top of which was a freshly poured slab, was used by the family on the very day of the pour.

The project represented everything Aura Entle aimed to achieve – delivery on time, within budget and ultimately to see convenience passed down to the Client

Makro Riversands

What is the purpose of the structure/ project?

The structure serves as a retail centre.

What was the brief to the architect?

To maximize space utilization and minimize construction time.

Give a brief description of the structural framing. What type of sections were used (e.g. hollow, cellular, I beams etc) and why?

The main roof structure consists of girders and castellated rafters. Castellated beams were used for aesthetics and to reduce the overall weight of the sections along the span. Also to increase the spanning capabilities.CHS were used in the barrel vaults as an architectural feature.

Were there any challenges in the fabrication of the project from the engineer’s design – if yes, please tell? Tell more about fabrication and erection process if it was complex, difficult, innovative etc.

The fabrication of the barrel vault needed to be completed to a tight tolerance in order to ensure correct fitment of barrel vault sky –lights.

It was complex due to the fast-track nature of the project. Whereby close coordination was required between the civil contractor, steel contractor, building contractor, sheeting contractor, fire services, mechanical services in order for the works to be completed in the required sequence within the building footprint.

What is special/ unusual/ innovative/ aesthetic about the steelwork/cladding in this project?

The structural steel barrel vault arches on Makro structures have become a nationwide symbol of the Makro brand.

How did the project team work together (e.g contractor involved early, challenges/ ease of communication etc.)

MPW detailing office worked in close communication with the engineering and architecture team in order to ensure discrepancies were picked up within the detailing phase, to allow for adjustments to be made prior to fabrication. This resulted in a structural system which very closely resembled a Mecano set. Therefore it allowed us to reduce erection time on site. All contractors on site worked in close unison moving from section to section ensuring all the requirements were met timeously.

Loftus Park

Loftus Versfeld and its surroundings are set to get a massive economic and aesthetic upgrade with the construction of a Rl.2 billion shopping and office precinct. The project, which will consist of shops, restaurants, an office park, a hotel, a gym and a sports museum. This futuristic and environmentally friendly project will be positioned at the corner of Park and Kirkness streets and will be bordered by Pretoria High School for Girls and Loftus Versfeld Stadium. The development will occupy the entire tennis court and the open field parking on the north side of the stadium. The buildings are all green star rated. The old Northern Transvaal Tennis Union heritage building (the old Sin Bin) will also be restored and will find a place within the precinct. It’s the Heritage Building of the Northern Transvaal Tennis Union. It was their old clubhouse and they have relocated to Groenkloof, they will be restoring the building and will make commercial use of the building.

Several tenants had already been signed to rent space in this comprehensive development which would include premium grade commercial office space, hand-picked shops with novel retail outlets, a state-of-the-art gym, restaurants, an open-air piazza, a sports medical center, a sports exhibition center and a four-star hotel.

Delport announced that the mixed-use development will host the first Radisson RED hotel in South Africa. The world’s first Radisson RED Hotel opened in Brussels, Belgium only last month.

“Loftus Park is proud to welcome this new concept as part of the project’s first phase,” he said.

Radisson RED is a new lifestyle select brand inspired by the ageless millennial mindset and has a forward-thinking design.

Situated on the northern side of Loftus Versveld, Loftus Park would be built in three phases and could also see the northern facade of the iconic rugby stadium being refurbished to fit in with the look and feel of the new development.

“Service upgrade initiatives for Loftus Park include the upgrading of traffic intersections, reducing traffic bottlenecks in Park and Kirkness streets with additional lanes, new traffic signals, traffic calming measures, street lights and pavements aimed at improving the flow of motorised and pedestrian traffic in the precinct as far afield as Magnolia Dell,” Delport said.

Hino Westmead

What is the purpose of the structure/ project?
To carry out alterations & additions to an existing facility for Hino trucks

Was the project envisaged in steel from the start? If not – why was it built in steel in the end? The existing steel structure did not change. Only sheeting was carried out.

How did the project team work together (e.g contractor involved early, challenges/ ease of communication etc.) The client was going to carry out roof sheeting direct which ultimately would have created split responsibility in the construction. The main contractor requested for the roof sheeting to be done through the main contract to prevent split responsibility and potential program issues.

Gibela Train Station Cladding

Gibela Rail Transport Consortium is a new empowered South African rail company tasked with the revitalisation of rail transport in South African metro areas. The purpose of the Gibela Train Station project was to create a train manufacturing facility in Nigel, Gauteng.

A number of processes needed to be housed within the facility and the design team was tasked with creating a series of specialised warehouses that were not only functional and could accommodate all of the production processes, but were also aesthetically pleasing. Steel was chosen from the outset because it would enable a streamlined construction process that would meet the client’s budget restrictions.

The structural framing at the Gibela Train Station consists of I-beam sections from the columns. The entrance building has cellular beams while some of the warehousing buildings had lattice columns that were also made up of I-beams. The structure also included a cantilever canopy of 1.25 metres.

Over 300 tonnes of cladding was supplied for the 55000 m2 area that needed to be clad. Global Roofing Solutions’ Klip-Tite was specified for the project, which involved large spans and large sheeting. The sheeting was rolled on site and the product enabled the design team to achieve the desired results. A Safflok 700 0.55m profile was used for the roof and a 0.55 trim flute cladding was used for the vertical sections.

Many of the project team members were located at the engineering consultancy, which helped to facilitate collaboration and information sharing. Instead of the project team meeting on a weekly basis, the close proximity of many of the team members created a positive dynamic and contributed to the success of the project. The Gibela Train Station was delivered on time and within budget.

Empowered Spaces

The new building for High Definition Interiors is located on 22 Holt Street Sandton. The brief to the architect was to create an A-grade office building that would maximise the views over the Johannesburg skyline (particularly the Randburg area) and maximise the bulk provided by the site.

The building was envisaged in steel from the start and the entire building was clad with steel, giving it an industrial look and feel. Global Roofing Solutions supplied over 8 tons of Brownbuilt 406 to clad the 1170m2 area. The architect chose this cladding solution as it provided the right warehouse feel, but also offered a sleek and clean aesthetic.

The cladding of the High Definition Interiors building is different to many other office buildings as this type of sheeting is typically associated with a warehouse. The architects are pleased with the result as it gives a new and different appeal to the office.

The building has an internal skin of brick to meet the thermal requirements for an office building, with the steel structure being fixed to the structural columns. The structural framing consists of I-beams and C sections.

The side cladding and aluminium cappings are supported on a light weight structural frame made up of cold formed lipped channels, and the roof sheeting is supported on a series of mild steel rafter beams and trusses in order to create a column-free double volume space on the first floor office level. These steel sections were chosen for their light weight structural efficiency in reducing the overall steel tonnage and hence project costs.

In addition to supporting the side cladding and roof sheeting, the structural framing system of the building needed to be concealed and designed around the double volume flush glazed curtain wall on the western side, and the large raking flush glazed corner window on the eastern side. The same principle applied to the sub-frame supports for the composite aluminium capping features that framed the corners of the building. This involved intricate detailing of the structural steel and close coordination with the Engineer, Steel Detailer and Architect.

The project team had a good and collaborative dynamic which contributed to the success of the project.
