JTK Consult (JTK) was engaged by the Public Works Department (PWD) Malaysia to carry out a comprehensive investigation of the Hospital Sultanah Aminah (HSA) in Johor Bahru. The hospital constructed in 1941, was showing some deterioration, and there were no available historical records (eg. no project specifications, structural and architectural drawings, etc). The building was to have its structural integrity restored whilst maintaining its historical architectural features. The structure is a six storey reinforced concrete frame with a brickwork facade and reinforced concrete piled foundation. The investigation was completed in 1989. This was followed by a remedial repair contract which started in 1992.
The investigation stage work included material condition survey, structural assessment, reproduction of architectural and structural drawings, materials durability assessment, repair assessment to meet the intended service life, contractor tender pre-qualification, tender documentation, tender assessment, and consultancy supervision of the repair works. The consultancy work involved a technology transfer of expertise to the PWD so they could build an in-house expertise for appraisal of reinforced concrete structures.
The investigation and assessment confirmed the structural integrity of the hospital had not been severely impaired during its 50 year life. Some repair works were required to restore the structural adequacy and provide protection against material durability deterioration in future. JTK supervised the repair works over the period 1991-1994 to implement the course of action agreed with PWD, Ministry of Health and HSA while the hospital was fully functional.
