Corporate Social Investment Concor optimised the socio-economic impact of the Compensation Fund House refurbishment project by prioritising local procurement and community upliftment, while aligning its corporate social investment (CSI) efforts with the client’s objectives. A key project target was to source at least 30% of the total project value - across subcontracting, supply and labour - from businesses and individuals within the local ward. Achieving this required a coordinated process of SME screening, selection and incubation, carried out in collaboration with the ward councillor, the Public Steering Committee (PSC), and the client-appointed Community Participation Consultant (CPC).

the staircase to the required width, this project revealed a further complication: the existing concrete cover - the depth of concrete over the rebar - was below the minimum required by modern codes. To resolve this, Concor applied several remedial strategies. These included increasing the concrete cover by thickening the new concrete layer or using specialised chemical treatments such as waterproofing agents and rust inhibitors to protect the exposed rebar. Structural elements such as concrete columns were also carefully tested. While these were expected to meet a strength of around 25 MPa, some were found to register as low as 5 MPa. In addition, scanning of concrete slabs revealed significant inconsistencies in rebar spacing.
