Lancaster Plus Bridge across the River Lee, Cork, Ireland: 2005 - 2006 Client: Niall Fitzsimons & Co. Scope of Services: The bridge provides access to a new hotel and residential development in Cork. For environmental reasons, river piers were not permissible; the bridge had to comprise a single span of 24m. Due to hydraulic freeboard requirements and the levels of the existing approach roads, a simply supported span was not feasible. The design put forward by EXSTRADO to meet these design constraints comprised a simply supported drop-in span of 15m length supported on large abutment cantilevers, which in turn are supported on a set of 900mm diameter tension and compression piles. Due to the fact that large hogging moments could now be developed at the abutments, the central drop in span could be made slender. It comprises precast concrete rectangular beams, curved in elevation, acting compositely with an in-situ concrete deck slab. The abutment cantilevers, with a mass of 62t, are in reinforced concrete, and are connected to the tension piles by means of diameter 50mm Macalloy bars prestressed to full working load. The design not only complied with all environmental, hydraulic and aesthetic requirements, but also has the added benefit that all construction works could take place from the riverbanks, with no disturbance to the river channel. The completed structure is clad in cut limestone, to yield the required architectural finish.

South African Jewish Museum, Cape Town, South Africa: 1999-2001

Client: Kaplan Trust Scope of Services: Design of the reinforced concrete structure supported on Franki Piles. Most notably, conceptual and detail design of the ø 8,60 m, 5,55m high helical staircase, which completes 1

1/4 revolutions whilst being supported only at its ends. The staircase is the central

architectural feature of the museum. The detailing of the support sections presented a particular challenge, due to the high vertical and torsional shear stresses prevalent there, as well as large bi-axial moments. The section varies in depth from 650mm at its supports, to 350mm at the midspan sections. The cross section is trapezoidal, in order to maintain the position of its centroid as close as possible to the axis of the staircase. Design to SABS 0160, South African equivalent to BS8110.

3.4 SPECIALISED STRUCTURES Southern African Large Telescope (SALT), Sutherland, South Africa: 2000-2003 Client: SALT Foundation Scope of Services: Project Management, structural design and specifications for the Southern African Large Telescope facility at Sutherland in South Africa. The telescope will be one of the largest in the world, with a hexagonal mirror of some 11.5 m in width. In addition to the design of all reinforced concrete and structural steel elements of the facility, a complete spectral analysis of the CCAS (Centre of Curvature Alignment Sensor) Tower was carried out to accurately predict the effects of structural excitation due to vortex shedding around the tower, in order to ensure that associated harmonic displacements remained within specified limits so that the operation of the highly sensitive optical equipment housed in the tower would not be impaired. The entire project, currently under construction, has a capital value of R245 million and will be commissioned during 2004. Design to SABS 0160, South African equivalent to BS8110.
