Temporary Works Management Temporary Works management depends on a clear definition of authority, competence, and communication flow. 6.1 TW approval No Temporary Works shall be installed, erected, or put into use until all required approvals have been formally obtained from the relevant authorities. This includes submission and acceptance of design calculations, d rawings, method statements, and any supporting documentation necessary to demonstrate compliance with applicable standards and project requirements. 6.2 Compliance • All Temporary Works shall comply with applicable laws and regulations of the Saudi Arabia, as well as recognized engineering standards and best practices. Abyatona shall ensure that the design, execution, and maintenance of Temporary Works meet statutory requirements and reflect sound engineering judgment to safeguard safety, quality, and structura l integrity. • All risks associated with Temporary Works shall be identified, assessed, and included within the overall project risk assessment and risk management process. Abyatona shall ensure that appropriate mitigation measures are implemented, regularl y reviewed, and updated throughout the duration of the Works to maintain safety, compliance, and control of identified risks. • All Temporary Works method statements shall be prepared, reviewed, and implemented in full compliance with the approved Project H SE Plan. The Contractor shall ensure that such method statements incorporate all relevant health, safety, and environmental controls, and are aligned with the procedures, standards, and requirements set out in the HSE Plan prior to execution of any Tempora ry Works. 6.3 Cost & Variation • All costs associated with Temporary Works shall be deemed included in the Contract Price, unless otherwise expressly provided for through a formally issued Variation in accordance Page 7 of 23 with the Contract provisions. This includes, but is not limited to, costs related to design, materials, installation, maintenance, and removal of such works. • Any changes to, or redesign of, the Temporary Works shall not, in themselves, constitute grounds for a Variation. Entitlement to a Variation shall arise only where such changes are expressly instructed or approved in accordance with the Contract provisions. All roles defined below align with BS 59 75 Clause 6, ISO 45001 Clause 5, and the ERC Construction Safety Manual (ERCSM 3.4.2).
