Project Overview

The brief was for an Office development of a 10,000m² P-Grade office space in Centurion, South Africa, designed for the South African Civil Aviation Authority (SACAA). The building needed to combine green technologies, modern design, and aviation-inspired aesthetics to meet the functional needs of SACAA while maintaining high environmental and operational standards. The facility required to achieve a minimum of a three-star Green Building Council South Africa (GBCSA) rating for water, energy, and waste management, and will accommodate 350 covered and open parking bays. The roof design will feature around 30% concrete roof and 70% sheeted roofing. The CAA steel roof structural consists of two wings symmetrically mirrored about a central roof structure.

Each wing has two levels that not only close the top of the new concrete office structure, but also curve down the sides, wrapping the concrete structure. In plan, the higher portion of these wings forms a trapezoidal footprint with th

Project Details
The apex and eave of the wings are curved. The main supports along these curves are trusses. The truss chords had to be fabricated as facets to form these curves. Each faceted chord element was designed according to the load in the chord to ensure costs remained as low as possible without sacrificing structural stability. The corners at the gable e
The biggest challenge was the shape and geometric requirements. 3D elements were broken down into simplified 2D elements to understand all the requirements of each element and the space it occupied. This gave a clear directive on how each element should be placed and designed for the global 3D space frame to perform as expected.
Benefits of Steel in this Application

The versatility of steelwork is illustrated in this project. The many facets of rolled steel make this project architecturally pleasing to the eye.
