While heritage restoration is a challenging sector, NCS has demonstrated their expertise and capabilities in assisting in the transformation of the Prince Henry Hospital into upmarket Apartments, whilst retaining significant elements of it heritage.
NCS were engaged by Ganellen to submit solutions for concrete rehabilitation that would increase the structural integrity and of the building with the focus on returning the structure to its original service life. NCS completed repairing concrete spalling within building columns, soffits and lentils. Additional coverage was also required to structural and reinforcing internal concrete floors.
Many factors were taken into consideration when selecting the restoration systems including heritage guidelines, limited space, project timeline and age of the buildings. Part of this consideration involved, core samples being taken and analysed. We worked closely with Consulting Engineers to ensure all measures were taken to understand the condition of the concrete materials and formulate the Design and Construct methodology. This resulted in a variety of solutions that exceeded Engineer specifications and met the client’s needs in extending the Service Life of the building.
To ensure the historic brick work was preserved Helifix-Helibeams were installed in the bottom two courses of façade brickwork to increase the strength of the structure and to support brickwork whilst works were undertaken. Ultra-High Pressure Hydrodemolition was undertaken to remove all concrete in the areas identified as needing repair or replacement.
Due to spalling, and the requirement for steel protection and reinstatement in parts of the structure, NCS repaired columns and soffits back to their original contour through the application of Xypex Megamix II and Xypex Concentrate. This system was approved due to its waterproofing and chloride resistance ability through crystalline technology and Xypex Megamix II’s capability of attaining high compressive strength in a short period of time.
“NCS have proven themselves to be a professional and competent Contractor across all facets of their business operations. They have successfully delivered on their Design and Construct solution that has allowed the conversion of a heritage building into modern apartments. This was a very complex project, and NCS ensured they delivered on time and within budget. NCS had an impeccable safety record onsite, performing within the top 5% of Contractors consistently through the contract. Furthermore in the Construction Industry, it is important to deliver on commitments. NCS have done this and more”. (Tim Sachs, Ganellen Project Manager)
