A secure, reliable and traceable supply chain.

CARES has been active in Singapore construction sector for the past decade and has achieved SAC accreditation to reinforcing steel products according to SS560:2016 since 2018. More than 75% of reinforcing steels imported by Singapore were produced from CARES approved manufacturers around the world.

CARES is delighted to announce the launch of its new service in Singapore – Certification for Specialist Builders (In-Situ Post Tensioning Works) and Factory Production Control Certification of Alternative Structural Steel to BC1.

The development of the CARES certification scheme for the supply and installation of Post-Tensioning (PT) systems in the UK and its acceptance by the UK PT industry played a key part in the Highways Agency lifting its moratorium on grouted post-tensioned bridges in September 1996.

As part of our global commitment to improving end-user confidence in the supply and installation of Post-Tensioning systems for concrete structures, CARES have been proud to work with the BCA to launch a product certification scheme for Specialist Builders (In-Situ Post Tensioning Works) in Singapore.

In developing the scheme BCA, supported by CARES have engaged with the main stakeholders which include the current BCA licenced PT Specialist Builders.

The Specialist Builders In-Situ Post-Tensioning Works is based on the demonstration of the continuing operation of the quality management system consistent with ISO 9001 together with the requirements of Requirements for Certification of Specialist Builders (RCSB) issued by BCA.

The scheme also requires that the PT kit and associated materials supplied for used in the PT installation are subject to Factory Production Control certification and tested in accordance with internationally recognised standards as appropriate. The installation scheme and these material controls ensure product traceability at all times, providing confidence to project owners.

CARES also launch the certification scheme in Singapore for Factory Production Control Certification of Alternative Structural Steel to BC1 (Design Guide on use of Alternative Structural Steel to BS5950 & Eurocode 3).

There are a number of documents that deal with various aspects of post-tensioning of flat slabs, however none comprehensively deals with the technical aspects of post-tensioning in building construction. Consequently, CARES has produced a model specification as a guide to specification writers, which take account of regional specifications and state building control requirements.

Under the provisions of this design guide (BC1), alternative steel materials not manufactured to British Standards may be allowed in structural design based on BS 5950 and SS EN 1993. To be consistent, this design guide outlines the material performance requirements and quality assurance requirements to be imposed on all steel materials, including those manufactured to British Standards, intended for use in accordance with BS 5950 and SS EN 1993, in the context of Singapore.

Training requirements

CARES Registration Scheme for Competent Post-Tensioning Personnel’ is a key part of the CARES SPT01 Scheme. CARES requires PT companies to provide the training for PT supervisors and operatives and assess the effectiveness of the training. Once personnel have reached a satisfactory level, evidence of achievement is to be sent to CARES which then issues identity cards which must be worn on site. PT ID cards are issued to approved Firms for their PT personnel. Approved Firms should apply to CARES' office for the cards by submitting the application form (available from CARES office) together with a photo and PT training record for the personnel required.

Review of supervisor competence is a key component during the regular PT site audits.

Quality (ISO 9001), Environmental (ISO 14001) and Occupational Health & Safety (ISO45001) Management Systems Certification

ISO 9001, ISO 14001 and ISO 45001 are all based on Annex SL (ISO high level structure) overarching by a common framework to all management systems which consistently aligns different management system standards, meanwhile additional discipline-specific requirements are applicable to each relevant management system standard under the top-level structure and apply common language across all standards. With these new standards in place, organizations will find it easier to incorporate their management systems into the core business processes and get more involvement from senior management.
