Underground Water Tank Project

A large-scale infrastructure project involving excavation, reinforcement, and concrete construction for water storage facilities.

Client KFSH&RC
Duration 2018-2021
Role Project Manager/Civil Engineer

Project Overview

The Underground Water Tank Construction project at King Faisal Specialist Hospital & Research Centre (KFSH&RC) was a critical infrastructure initiative designed to enhance the facility's water storage capacity and emergency preparedness.

As the Project Manager and Civil Engineer, I led all aspects of this complex construction project, from initial excavation and foundation work to reinforcement installation and concrete pouring operations.

The project required precise engineering calculations, careful coordination of multiple construction teams, and strict adherence to safety protocols due to the depth and scale of the excavation work involved.

Project Details

Site Preparation

Managed extensive excavation operations, ensuring proper soil removal, site leveling, and preparation for foundation work. Implemented dewatering systems to maintain dry working conditions.

Structural Design

Collaborated with structural engineers to finalize reinforced concrete designs, ensuring water-tightness, structural integrity, and compliance with seismic requirements for underground structures.

Reinforcement Work

Supervised the installation of complex steel reinforcement structures, ensuring proper spacing, coverage, and connections according to engineering specifications and building codes.

Concrete Operations

Coordinated large-scale concrete pouring operations, implementing proper vibration techniques, curing procedures, and quality control measures to ensure structural integrity and water-tightness.

Safety Management

Implemented comprehensive safety protocols for deep excavation work, including proper shoring, access control, fall protection, and emergency response procedures to ensure worker safety.

Documentation & Compliance

Maintained detailed project documentation, including daily progress reports, material testing results, and compliance certifications to ensure adherence to project specifications and regulatory requirements.
