Sea Water Reverse Osmosis Desalination Plant Phase I (Acciona) with daily capacity of 210,000 m3 and Phase II Joint Venture (Acciona & RTCC) with daily capacity of 630,000 m3 per day. (Al-Khobar).

MAIN FUNCTIONS AND RESPONSIBILITIES:
– Proficient in preparing detailed Civil, Mechanical, Process, and Electrical design drawings for both onshore and
offshore projects, including greenfield and brownfield developments.
– Drafted Mechanical General Arrangement (GA) drawings, piping layout plans with sections and elevations, and
detailed isometric fabrication drawings.
– Developed comprehensive utility infrastructure drawings including stormwater networks, Lifting stations, sewage
systems, Concrete Chambers, sanitary water supply, Firefighting systems, street lighting, and road layouts for land
development projects.
– Created subsea piping layouts, profiles, and detailed sections using GRP and HDPE materials (up to Ø3800 mm),
including pipelines extending 2km into the sea.
– Verified field-executed works by cross-checking dimensions, elevations, specifications, and equipment
placements for accurate as-built updates.
– Produced detailed as-built documentation for Architectural, Structural, Civil, Mechanical, and Electrical disciplines,
incorporating actual site conditions and changes.
– Ensured compliance of as-built drawings with project standards, client specifications, and local authority
regulations.
– Prepared, revised, and updated shop drawings, red mark-ups, and as-built drawings, ensuring clarity and precision
for construction execution and handover documentation.
– Reviewed subcontractors’ construction drawings, technical submittals, and responded to RFIs and technical
queries to ensure alignment with design intent.
– Designed high voltage cable duct banks from GIS to transformers in brownfield environments, ensuring
compatibility with existing infrastructure.
– Oversaw the design and coordination of HCIS-compliant security systems, including fire protection and CCTV
systems, in line with Saudi HCIS standards.
– Proposed constructable solutions for technical challenges encountered during execution, including spa􀆟al
constraints and system clashes.
– Collaborated with site engineers, QA/QC inspectors, and project managers to incorporate field modifications into
final design packages.
– Utilized mock-ups and site simulations to validate technical feasibility and resolve coordination issues during
design and construction phases.
– Acted as a technical liaison between client, consultant, and subcontractors, providing expert guidance on drawing
interpretations and construction strategies.
– Monitored drawing revisions, tracked version control, and implemented consultant/client feedback for prompt
approvals.
– Led and coordinated drawing submissions, ensuring timely delivery, quality checks, and proper documentation
protocols.
– Managed document control activities including DCR responses, drawing logs, and drawing index tracking for
ongoing and final submissions.
– Supported multi-disciplinary design teams by ensuring interdisciplinary drawing alignment, avoiding
discrepancies in construction phases.
– Demonstrated proficiency in AutoCAD, Civil 3D, and other CAD platforms, with a focus on efficient drafting, layout
optimization, and data integrity.
