Wilcox Road

Purpose of the structure/project?

The structure is a large span logistics warehouse in Prospecton, near the Durban Port.

What was the brief to the architect?

Maximise the land for a user friendly logistics warehouse.

Was the project envisaged in steel from the start? If not – why was it built in the end?

Yes. The structure was lifted by 5m (during fabrication) due to tenant requirements. This was done with concrete columns and some revisions in shop to the steelwork.

Give a brief description of the structural framing. What type of sections were used and why?

Castellated columns, lattice girders, angles, tubes, and 450MPa purlin sections.

Give a brief description of the cladding process (complexity, difficulty, innovation)

The greatest difficulty in the cladding was in the sheet length due to the Kliptite concealed fix used. In high winds and due to the roof height and location winds were often an issue and congestion on site only allowed for site rolling in specific areas, requiring additional labour to move sheets on site and up on the roof

Were there any challenges in the fabrication from the engineer’s design. Tell more about fabrication and erection process if difficult, complex, innovative

No.

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

No. However the Kliptite sheet offered an excellent solution to the client, design, and architectural requirements.

How did the project team work together (contractor involved early, challenges, ease of communication)

Excellent. An outstanding facility completed to the design specification, and forming an integral part of the port and Prospecton sector.

Tons of structural steel used 420 tonnes

Videojet Paarl

What is the purpose of the structure/ project?
We were briefed to design the new VideoJet Paarl office and workshop, which is to set the tone for the future of this subdivision of the HG Molenaar brand. The location set at Driebergen Lane,Dal Josafat, on the street face of an existing factory setup, and needed to integrate itself with the existing building. HG Molenaar are pioneers in food process machines, and have the ability to manufacture any high end steel features – this project, would thus, as a showcase for their ability, in a new area of construction, be a sample for their existing and prospective clients, to assert instant respect, trust and faith, in HG Molenaar, to deliver what they promise.

The building is used as an office space, reception and workshop for the VideoJet brand, its MD, support staff and sales components.

What was the brief to the architect?
Iconic building that can be manufactured by HG Molenaar – ie use a lot of steel

Was the project envisaged in steel from the start? If not – why was it built in steel in the end?
Yes it was simpler to connect to the existing steel structure, the client could make the structure, and it would be faster.

Give a brief description of the structural framing. What type of sections were used (e.g. hollow, cellular, I beams etc) and why?
IPE 200 – Mainly – this section is considered for its aesthetic appeal as its structural strength – client wants to add on third floor at some stage
305x165x40 I Sections – All Beams
406x140x46 I Section – for its Cantilever
101.6×4.0 CHS Struts on Custom plates – with custom turned steel connections
25 Dia Solid rounds to Hang the bridge and floors
Y10 and Y12 Structural Steel to concrete reinforcement
Façade Lazercut screens by client hung on Steel angles – Sheets are 3000x1500x2mm Mild Steel

Give a brief description of the cladding process (complexity, difficulty, innovation etc)
Complexity – this was simple, we cut a few sample panels to see how we would fix, and whether the apertures were working – also checked the robust nature against potential theft and vandalism. The answer was simple – the design was very difficult to pin down with many stakeholders and opinions.
Innovation – simply used available technology – screens assist in controlling light and vandalism to glass facade

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.
At some stage there was a small 2-3cm discrepancy in height – the entire structure was jacked up and the error rectified with spacers.

What is special/ unusual/ innovative/ aesthetic about the steelwork/cladding in this project?
All steel was worked and machined on site. The client’s involvement assisted greatly with the process. It was also 3-dimensionally pinpointed prior to construction – so the fixing and bolting was a precise mathematic.

How did the project team work together (e.g contractor involved early, challenges/ ease of communication etc.)
Entire building was documented up front – no variations, no site supervision, no changes – smooth simple exact.

Victor Daitz Mathematics Centre

The King Edward VII Mathematics Centre is located at King Edward VII School in Johannesburg. The project is a classroom facility with a hockey pavilion comprising both an upper viewing deck with kitchenette  facility and lower area of team ablution/change facilities, as well as a larger ablution facility for scholar use.

The brief to the architect was to propose a scheme as a fund raising platform from Old Boy donors. Two donors, Victor Daitz Trust and Edgar Droste Trust (both deceased Old Boys) stepped up to assist.

The project was to comprise initially 4 x mathematics classrooms and ablution facilities. This later expanded to incorporate a hockey pavilion and ablution facilities. The idea was to maximise the  small  space adjacent other classroom wings and minimise the number of peripatetic teachers.

From the outset, the project was envisaged as a combination of steel, concrete, brick and aluminium. The sunscreen roof was envisaged as a steel filigree screen with cutout patterns and as one of two elements which could give the project life, the aluminium balustrade being the other. The elements of geometry and mathematics are used here as an inspiration for the creation of their forms.

The steel elements of the project vary from Universal Columns to square hollow sections which are used as a giant order to the upper canopy roof to maximize the verticality as an offset to the flat canopy. The rafter and rear screen elements are IPE members and C-channels. The steel sheet canopy is suspended.

From an engineering perspective the challenges to the canopy roof were in the methodology in which the sheeting is suspended from its structure, as an inverted solution. The sheeting is read as a hovering plane that floats above the parapet walling at the building edge. The large over-sailing cantilever sheet at its point hangs off an extended beam and the framed system of beams and rafters. The cantilever similarly covers the passage way, whilst the hockey pavilion sheeting extends the roofline to match. The screen is grounded on double length columns which bypass the building and soar vertically straight to the canopy.

The challenges of fabrication were in the amount of steel sheet that was to be removed in the patterning. Too much cut out created a bend in the sheet, and as such the pattern had to be manually adjusted in order that it read as random, natural and poetic. Most of the panels therefore had individual patterning and as such this required close monitoring on the cutting and installation process.

The resulting aesthetic is a sensitive approach to mathematics and geometry which creates patterns in light and shade which varies constantly throughout the day and night. A visual delight juxtaposed to previous hard insensitive buildings.

The project team worked tightly together from project concept to project fruition. Both the  main  contractor and steel sub-contractor took the project on board as it was felt that it would be a challenge and something out of the ordinary for them to realize. The project team rose to the challenge and the process was fun.

We would like to think the results speak for themselves.

V&A Grain Silo Complex façade

What is the purpose of the structure/ project?

 The V&A Grain Silo was built in the 1920s to store grain for export out of South Africa. This industrial heritage complex was rejuvenated as the central feature of the world class green Silo District development. Heatherwick Studio was engaged to conceptualise the redevelopment that is now occupied by The Zeitz Museum of Contemporary African Art (MOCAA) and The Silo Hotel.

The most noticeable and significant aspect of the use of steelwork on the project are the 82 pillow windows on the building. These are installed to the rooms and restaurant of The Silo Hotel and on the top floor of the Zeitz MOCAA. The windows on the restaurant level of the hotel are 3.8m wide x 5m high and the windows to the hotel rooms are 3.5m wide and range in height 5m – 3.8m.

On the top floor of the Zeitz MOCAA the windows are 4.9m wide x 5m high and include corner windows consisting of two halves, 3.4m wide x 5m high, which are bolted together and sealed on site. Other significant use of steelwork in the façade packages include:

Zig-zag windows: Folded glass windows built into the silo walls at the museum ground floor, supported by steel flat plate structure.

Trafficable skylights: 12 trafficable glass panels supported by steel structure to the top of the silos over the museum atrium

Skylight: Glass skylight between the  silo building and elevator building supported by steel structure

What was the brief to the architect?

 Heatherwick Studio’s brief was to give new life to the redundant industrial building, repurposing it into something new for the waterfront. Following the studio’s suggestion of installing convex windows into the upper storeys of the building to transform it into a glowing beacon for the waterfront and afar, Arup further developed the concept of the pillowed windows.

Was the project envisaged in steel from the start? If not – why was it built in steel in the end?

For the pillow windows alternatives to steel were explored, such as aluminium. Steel was selected because of:

The capacity of local industry to carry out this work to the required tolerances

Robustness of steel welding, which is not subject to reduced strength in the heat affected zone as is the case with aluminium.

Cost effective for the complex geometry.

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

The pillow windows are fabricated from flat steel plates 50 x 16 that are welded to one another to form the bulging geometry of the pillow and welded to the 160 x 80  rectangular hollow section (RHS) forming the perimeter frame. The choice of flat bars / plate was to minimise the appearance of the framing from inside and maximise the views through the window. The frames are positioned at each facet between the glass panels, with the depth of the plate orientated toward the room and roughly perpendicular to the bulging geometry. Aluminium glazing profiles where mechanically fixed to tapped holes on the outer edge of the flat bars / plates. The flat bars act as domed arching structure for wind loads carrying axial loads and bending moments. The perimeter RHS provided additional width for the perimeter weather proofing and structural strength for transferring the framing wind loads to the four steel brackets used for fixing the window to the concrete structure. The perimeter frame also included a temporary hoisting bracket bolted to the frame during hoisting.

The window includes double glazed triangular panes, structural silicone bonded to the aluminium glazing profile  on the outside face of the steel frames. These window panels were installed in the factory and the windows were transported and installed fully glazed and sealed.

Were there any challenges in the fabrication of the project from the engineer’s design – if yes, please tell?

Achieving the pillow window geometry was the most significant challenge. The steelwork geometry was defined in detail by Heatherwick Studio and Arup using parametric 3D modelling techniques. This allowed the fabrication aspects, such as orientation of framing and alignment of framing at joints mitre lines to be established in a 3d model developed by Arup, while allowing the geometric parameters, such as the geometry of the bulge, framing positions and window size to be fully defined by Heatherwick Studio.

The parametric model was used to generate a 3D model of each of the five window frames, that included the required member size and orientation that was provided to Mazor, the steelwork fabricator, to produce their steelwork shop drawings.

Building this complex geometry was a challenge that was tackled by Mazor through production of steel jigs to define the geometry of each of the window frames. The steel members were assembled into the jig and tack welded into place, removed from the jig and then the welding completed. Careful planning was required in fabrication of the jig and planning of the welding to ensure that all welds could be accessed and welded after the framing was tack welded together. To achieve the neat appearance at the joints welding splatter at these positions was ground smooth and the joints body filled to achieve a high level of quality at these nodes. Mazor had a specialist team responsible only on dressing and shaping each of these nodes on all the windows.

Transporting and installing was another challenge as the pillows were made and glazed as one assembly in a factory (up to 5074mm x 5022mm in size) and transported to site complete. Careful handling was required to ensure that the glass was not damaged in the process. With the window fitting tightly between the concrete beams and columns and inside of the concrete, façade installation was challenging. To reduce the risks it was desirable that the position of the windows during hoisting was similar to installation position of the window and that the hoisting cables did not clash with the concrete structure. To achieve this the design incorporated a temporary lifting bracket, bolted to the perimeter frame,  that aligned  the centre of gravity of the glazed window with the lifting cables, which also positioned the cables outside the concrete face.

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

The use of parametric 3D modelling techniques that respected the detail fabrication considerations for the steelwork assembly and also enabled the architect to shape the desired geometry.

Complex geometry achieved with steelwork fabrication.

Quality of finishing achieved particularly at the nodes as a result of the 3D modelling considerations and the finish quality achieved by the contractor.

Rejuvenating the Grain Silo in such an architecturally astonishing manner has created a unique centrepiece for the Silo District.

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

Close collaboration with the architect was necessary to realise technically challenging design intent in a pragmatic and buildable manner. Key to this collaboration was combining Arup’s deep design knowledge with market leading parametric capability to create a model that allowed the architects to drive the aesthetic resolution within a technically feasible framework.

Understanding the geometry to high level of detail before tendering ensured that the desired outcome. Communicating the design intent to the contractor and reviewing the contractor’s 3D shop drawing model shortened the shop drawing review phase and allowed for comparison of the design intent model and shop drawings model a 3D virtual environment rather than on 2D drawings, lessening the possibility of errors.

Tradeport City Deep

What is the purpose of the structure/project?

The main purpose of the structures is to serve as a warehouse facility.

What was the brief to the architect?

The warehouse to be designed with large internal column spacing, creating a versatile open storage area and dedicated racking layout with minimal loss of space due to column interference.  The warehouse spanned over a total of 30,000 m2 in total comprising of three storage segments inside with a 12m clear eave height

 Was the project envisaged in steel from the start? If not – why was it built in steel in the end?

Yes, a combination of a face brick plinth wall with cladding onto a steel structure above plinth wall with roof structure and canopies. A Structural steel truss system comprising of large span girder trusses and secondary lattice trusses was chosen to provide the required clear span attributes.

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

A combination of hot-rolled H-, I- and Angle Iron sections were used in parallel with cold rolled lipped channels.

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 uniformity in structural shape and sections selected for the design made the fabrication process easy where the erection process could be streamlined.

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

 The use of Tekla Structures as primary draughting tool facilitated in the communication between design, Engineer, Structural Steel Detailer, and Contractor. Quick response, effective communication, and the ease of understanding the structural scope, that combined with professional team meetings and inspections.

Tons of structural steel used 720 Tons

Stortemelk Hydropower

Architect’s Motivation
Situated in the rolling foothills of the Drakensberg Mountains, along the banks of the Ash River, the Stortemelk Hydroelectric Plant attempts to celebrate the importance the plant holds in producing clean, responsible electricity in South Africa.

Comprised of a number of building skins, the design approach intended to create different experiences of the plant from the exterior, & from within the interior. Clad in Corten Steel & Polycarbonate sheeting, the architecture is intended to be of its landscape, while still allowing for good light quality to penetrate into the plant interior. Articulating the façade with slotted window openings allowed for the perception that the electrical production of the plant is spilling out into the surrounding environment, creating a beacon in the landscape.

On approach to the site, the Corten Sheeting reaches up into the skyline, announcing the building & adjacent river from a distance. The lightness of the steel construction is then contrasted by the far more stereotomic design of the rest of the plant, which protrudes from the river bank as a plinth.

The challenge in the project was to create spaces for production, with minimal human interaction. Working hand-in-hand with an exceptional client made the realization of this celebration of production possible, creating architecture with respect for the responsible electrical generation the client creates.

Client motivation:
Our company carries a certain ethos that is core to every enterprise we undertake, namely the responsible production of energy in a South African context.

Our brief for the Ash River site was to create a housing for a hydro-electric plant that blended seamlessly with the surrounding landscape while also celebrating the responsible production of electricity. Many of our hydroelectric sites have been in operation for decades, which therefore require an approach that does not become a burden on the landscape or surrounding community.

The response to this brief from the architect achieved every aspect that we required, succeeding in both blending into the landscape, while also celebrating the plant’s functions. Beyond this, the design managed to create a spectacular light quality in the work areas of the plant through the use of polycarbonate sheeting.

The plant stands as the perfect mediation between the production of electricity from the river, & a well-considered addition to the Golden Gate landscape. In its entirety we believe this piece of production architecture fits wholly within our ethos of responsible creation, standing as a testament to what can be achieved without negatively affecting our unique countryside.

Silo 3 and 4

No. 3 Silo consists of three independent apartment towers containing 79 high end apartments over 11 floors. The three towers are connected by two steel framed lift and stair cores enclosed in expanded aluminium mesh, providing spectacular views of the harbour and V+A precinct.

Silo 4 essentially forms the base for the apartment towers and contains an upmarket gym facility over two floors. A double volume pool pavilion faces onto Silo Square, with panoramic views of the new Zeitz MOCAA Gallery, Silo Hotel and surrounding Silo District public spaces.

Expressed materiality and appropriate detailing were considerations equally as important as resolving the functional and programmatic requirements of the brief.

The character of the building was developed as an interpretation of the inherent “gees, (or ‘spirit’), of the precinct as part of a working harbour. In response to the surrounding built environment, the team explored further the themes of ‘fit for purpose, working harbour elements’, and in its making exploited the possibilities of composite structures – concrete and steel working together – in order to maximise the clear floor to ceiling dimensions of the apartments. Concrete up or downstand beams were entirely avoided in order to maximise the views out all of the Apartments, bearing in mind the overall height restrictions imposed by the Planning regulations and consents achieved. Furthermore, in order to construct the expansive floor plates, without resorting to more concrete columns and beams, steel framing ‘tied back’ to the central shear concrete cores, is used to assist in accommodating the floor plate cantilever. This ‘additional steel’, has been consciously ‘picked out’ in colours referencing the cranes and other elements of working machinery in the surrounding dock yards.

The cast-in load bearing steel frames primarily consist of 50mm diameter solid carbon steel bars, adjustable custom reverse thread couplers, welded up 230×90 PFC frames, 203x203x46 H columns and intricate welded end plate connections. Solid bars were chosen for the high tension capacity with minimal lengthening when fully loaded and the custom couplers were chosen to allow for tolerance and future adjustability. The Virgin Active steel roof structure is made up of PFC girders and trusses with solid round bar cross bracing. The exposed round bar cross bracing aesthetic was followed through on the external steel stairs, steel lift shaft structures and the external walkway bridge.  

The installation and sequencing of the load bearing steel frames were by far the greatest steel related challenges faced on site. These frames were designed to work compositely with the concrete structure resulting overall in a more slender structure. These frames were installed concurrently with the concrete structure which impacted on sequencing of slab construction, post-tensioning and temporary backpropping. The interface between concrete and steel required works to be highly accurate to achieve the desired aesthetic of exposed steel and raw concrete as well as work compositely as intended. Communication and co-ordination between the architects, structural engineer, main contractor and steel sub-contractor early on in the project was instrumental in achieving this.

The steel components used throughout the building are integral to the building’s structural integrity. This is expressed through the bold use of colour, further highlighting the key ‘elements’ in the structural assembly. Yellow is used on the façade steel elements that support the cantilevering balcony concrete slabs, while red highlights the two circulation cores connecting the three towers.

Cladding materials, including Rheinzink and perforated metal panels were also selected to respond to the harbour industrial shed aesthetic.

The collaboration of consultants, contractors, sub-contractors, specialist advisors and client was integral to the successful completion of No.s 3&4 Silo.

Revit was used as a production tool by all consultants (as was required by the client), and allowed the sharing of a central digital model across all disciplines.
