Botswana Lodge

What is the purpose of the structure/ project?

Main lodge and 5 sleeper units in private game lodge in Botswana

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

LSF for walls, Tubular steel and LSF for the roofs as they were all curved

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

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

Excellent relationship that has resulted in additional lodges in same reserve being done in LSF with same Architect

Tons of LSF used 36 Tons
Span of trusses and Kg/m2 (if applicable) Curved hot rolled beams with Light Steel infill.

Bosch Warehouse

Bosch is a prominent supplier of home appliances in South Africa. The company required a new factory and warehouse facility and appointed Empowered Spaces to design a facility that would ‘wow’ their staff and guests. The brief to the architect for the new facility, which is located in Witfontein opposite the Serengeti Golf Estate, was to design a factory and warehouse that ties in with the company’s corporate standards.

The warehouse was envisaged as a steel structure clad in sheeting from the start as this is renowned as the most efficient and cost-effective way to construct a warehouse. The structural framing consists of grinder trusses and a steel column structure which is supported by precast concrete columns.

What makes the new Bosch warehouse and factory unique is the use of corrugated iron sheeting, as this isn’t often specified for large warehouse structures. 125 tons of cladding was supplied to cover the 20 574m2 of warehouse area. Global Roofing Solutions’ Klip-Tite was the chosen steel sheeting for the project.

To speed up the construction process on site, the project team was appointed far in advance. This enabled the design team to issue the contractor with appropriate information ahead of schedule, which led to quick and efficient construction on site. The result is world-class warehouse that fits with the Bosch’s corporate brand and profile.

BMW Paint Shop re-roof

What is the purpose of the structure/ project?

Refurbishment of current paint shop.

What was the brief to the architect?

Remove leaking paint shop roof and replace with a thermally efficient built up roof system.

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

Innovation, twin skin built up metal roof system with uncompressed insulation, to correctly and   accurately provide the desired R value.

Difficulty short duration on project, over Christmas period in JHB’s rainy season, no extension of times were allowed, so continuous project acceleration was required.

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

Double skin, and larger than normal flashings. Over 75 penetrations in the roof with no back flashings.

Ashgate

The development comprises of three separate warehouse structures for the storage and distribution of chemicals, ancillary structures for staff and maintenance, hardstands and drainage required within the Umbogwintwini Industrial Complex on a brown field site.

Warehouses B&C were constructed with concrete columns up to 2.4 m height due to the rigidity offered and for the greater resistance to folk-lift impact and to lift the steelwork out of the flooding zone of any chemical spills. The warehouses have internal racking to store mainly non-flammable liquid chemicals in containers.  Warehouse C required particular attention to be paid to the horizonal deflection of the structure due to 13m high racking being placed next to the walls and the use of Very Narrow Aisle (VNAs) forklifts for the placing and removal of the containers.  The two warehouses are connected by a steel canopy spanning over the road and loading area.

Warehouse A is designed to store the flammable bulk chemicals in the facility, the warehouse was designed using precast columns and tilt-up walls to the underside of the steel roof sheeting, the steel roof is designed as non-continuous over the whole warehouse and instead is designed per compartment within the warehouse for safety in case of fire to prevent spread of the fire or fumes, progressive collapse and to limit the damage done in case of an explosion or fire.  The connection of the steelwork to the precast concrete elements required some unusual connection solutions for the purlins which are chemically anchored to the top of the wall.  An inverted plated U-bracket with fin plates and a slotted hole was designed to fit over the wall panels after the panel had been lifted into place and required input from the steel contractor and precast contractor to find a solution that would minimise drilling at height and time on site.

33 Baker Street

What is the purpose of the structure/project?

 To upgrade a very old building, to accommodate multiple tenants of which the main tenant is Standard Bank.

What was the brief to the Architect? 

To convert the existing building into a contemporary design with a status commensurate with the expectations of Sasol Pension Fund and Standard Bank as a tenant.

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

The curtain wall application to an existing concrete structure demanded a steel frame to achieve a modulated façade.

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

 Mostly I-Beams with angular trusses was used to hold the roof.

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

In view of the fluctuating conditions inherent to the existing concrete structure, it was required that steel substructures be designed which would have sufficient adaptability to address the different conditions whilst being able to achieve a modulated curtain wall design.

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.

Baker Street at its core was an upgrade of a current concrete building that was to be equipped with new structural steel to accommodate impressive looking glass and facades with paneling on the exterior. Essentially the overall appearance of the building was to be modified. The problem was getting accurate and existing concrete dimensions from site to work with the new Engineering/Architectural changes.

The Engineering drawings which was received had rugged ideas of what was required, in terms of the structural steel and, for a job like this, accurate measurements were of utmost importance.

In the end consultation and coordination between the Architects, Engineers, Glass-and Curved Façade team members, and Sheeting members had to work inwards from the outer most edges of the sheeting and glasswork.

However, the information provided by SVA, with regards to where everything had to be, completed, and getting the required support structures in design form, from the Engineers, allowed the Structural Steel Detailers to reconstruct what was needed from the ground up. The required structural steel did fit in, although tightly in places, but worked. Coordination on this level made everybody sure that everything would accurately fit in the end, especially using the exact three-dimensional (3D) Tekla models as well as proper DWG drawings, where everyone was able to double-check everything on their end. What followed from the new type of coordination with the Structural Steel Detailers leading the way was:  Problems being sorted out quickly in meetings, with nothing left unanswered where after it was checked and updated after meetings between all parties.

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

The steel frame principle allowed sufficient flexibility to achieve a curtain wall cladding accentuated with aluminum solid elements as well as utilizing the steelwork at roof level to support a balcony structure. The essential idea was to achieve a simplicity of structures that could be erected within a limited time.

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

The design demanded a meticulous coordination of the Engineer’ requirements, the curtain wall shop drawings and the detailing of the solid aluminum elements during the pre-contract documentation stage and on-site construction. The coordination of the various disciplines, as well as management of the process on-site, proved to be efficient.
