Restoration Works to Existing Heritage Conservation Building at Upper East Coast Road, Singapore
In view of the rising development needs and maintaining the history and character of the places, conservation and restoration of Singapore’s built heritage has become significant when continuing to grow as a city of distinction. Regulated by the Urban Redevelopment Authority (URA) of Singapore, a strict set of guidelines are in place for a building which has been demarked for conservation when undergoing restoration or upgrading works to preserve the architectural features. Often, this poses a challenge for the engineers who need to ensure the structural safety of the heritage building constructed decades ago without adopting a formal building code, by complying with the modern building design codes. The paper focuses on the complex and innovative engineering approach adopted to upgrade a conserved building built in the 1950s to be able to withstand the increased design loads. The structural analysis of the single-storey building revealed that the existing reinforced concrete (RC) slabs, beams, columns and pad footings had insufficient capacities to meet the new demand due to the low concrete grade, corrosion of the existing reinforcing steel which resulted in spalling concrete and severe steel sectional losses. A hybrid method including RC jacketing, Tyfo® Fibrwrap® Systems proprietary Fibre Reinforced Polymer (FRP) Composite Systems and Tyfo® Corrosion Inhibitor Systems (CIS) were adopted to successfully restore and conserve the building as per the stipulated requirements.
