Award Criteria

  1. Architectural Excellence
    Transnet, a large state owned S.African rail, port and pipeline company,seconded Stefanutti Stocks, a large Construction group operating in diverse Civil sectors, to provide temporary offices (Max 5 years) to Durban Harbour, Africa's busiest Port. Flat pack units were best design choice, based on their uniformity and flexibility for modular structures to create the operational space required in bespoke office layouts. Flat Packs can withstand level 1 hurricane in terms of wind loadings and are found to satisfy the structural requirements for multi-storey public occupancy certification in the S.African National Building stds, codes and regulations. Ideally suited to a marine environment, flat packs offer the durability and longevity in the harsh marine environment. Externally, the facility blends with its 110 000 sqft operational area, and creates a diverse and refreshing perspective, providing a safe and comfortable working environment.
  2. Technical Innovation & Sustainability
    Due to the high levels of Health and Safety required when performing construction tasks in a port, and the associated document submissions and on site delays, the majority of construction and fitment was done in the yard, and complete fitted units were transported to site. This required each unit to be numbered in the sequence that it was to be placed, which provided a seamless stacking of units in just 19 days. From a technical innovation & sustainability point, these units can be easily dismantled and removed to another location – without any serious fuss, as they are bolted together. Bolting of units together reduced the need for hot work permits on site, and once all fasteners were in place this produces a very rigid and sturdy structure to inhabit. It becomes an arranged ‘Lego set’ once all the pieces have been planned – and does not leave an ugly footprint of unusable rubble and remains when decommissioned at the end of its 5 Year life span.
  3. Cost Effectiveness
    Of primary cost concern was the high level of Health and Safety required for construction in a port environment. Such Health and Safety restrictions can debilitate a workforce and cause unforeseen and untold delays in the construction process, escalating costs out of economic proportion. With a fleet of crane trucks for modular unit movement, we were able to utilize in house cranes trucks to position the units, greatly reducing costs by increasing utilization. All units, both upper and lower floors were placed in just 19 days. In comparison to brick and mortar this would be an estimated 66% saving in time and 28% in material. A further saving in the project plan was the earlier assembly of the various unit conversions, whether for office /ablutions /kitchen, etc. all pre-equipped with necessary plumbing, electrics, insulation, floor & wall finishes & a/c units. The use of powder coated wall panels and aluminium trim finishing’s further reduce the maintenance of the structure.
