Phase A, known as the Preparatory Works phase, involved various tasks to lay the groundwork for the project’s implementation. Detailed design preparation, including the FIDIC Pink Book Tender and Tender Evaluation, was carried out for the flushing and CCTV-inspection of a 60 km sewer network. Additionally, a comprehensive Sewer Inspection Report was prepared, outlining recommendations for rehabilitation. Assistance was provided to the relevant authority, PEA, in the tendering and contracting processes. The supervision of works was conducted over a period of 10 months, ensuring compliance with project specifications. Furthermore, the management and monitoring of environmental and social issues, as well as occupational health and safety measures, were implemented during this phase.

Phase B, known as the Implementation Works phase, focused on the execution of the project. Detailed design, including hydraulic analysis, the FIDIC Pink Book Tender, and Tender Evaluation, were carried out for three Works Contracts, covering a total length of 24 km. The preparation of an Environmental and Social Impact Assessment (ESIA) was also undertaken. Support was provided in obtaining construction permits and licenses, while assistance was extended to PEA during the tendering and contracting stages. The supervision of works continued for 18 months and is currently ongoing. Throughout this phase, the management and monitoring of environmental and social issues, as well as occupational health and safety measures, remained a priority. Furthermore, assistance was provided during the Defects Notification Periods, which spanned 12 months, ensuring any issues or concerns were addressed promptly.
