Large-scale underground utility networks — sewer, water supply, fire protection, and irrigation — engineered and installed across kilometres of Saudi developments.
A Scope of Work (SOW) for Civil & Infrastructure Works defines the exact tasks, deliverables, and boundaries for preparing a site and building the foundational networks necessary for development. It covers Earthworks, Utilities, Roads, and Structural Foundations, serving as the blueprint that protects against budget overruns and scope creep.
The comprehensive breakdown of a standard infrastructure and civil scope of work includes:
7,000m Sewer · 10,000m Fire · 14,000m Irrigation · SAR 20M · 2024–2025
Sewer, Water, Fire & Irrigation Networks · SAR 9M · 2024–2025
Planning a civil infrastructure project in KSA?
Fabrication, erection, and turnkey delivery of steel structure buildings — warehouses, factories, industrial hangers, and prefabricated structures across the Kingdom.
A steel structure scope of work for a residential building outlines the engineering, fabrication, and erection phases. It details specific structural elements (beams, columns, trusses), material grades, shop drawings, connections, and delivery. It ensures the home's steel framing is built safely, meets load requirements, and passes building regulations.
A comprehensive scope of work for residential steel construction generally breaks down into these distinct phases:
Client: Al-Marai · SAR 8.25M · 2018–2019
Client: King Saud University / G.O.S.I · SAR 7.08M · 2013–2014
Client: Mohammad Hussein Industries · SAR 0.67M · 2024
Need a steel structure delivered on schedule?
Complex industrial construction including power plant civil works, chemical warehouses, metro rail structures, and large operational facilities — precision-engineered for demanding environments.
The Civil and Structural (C&S) scope of work for industrial projects defines the engineering, procurement, and construction (EPC) requirements. It covers site development, foundation design, and load-bearing steel frameworks, which must be tailored to heavy operational loads, equipment integration, and harsh operating environments
The scope of work is typically divided into four main project phases:
This phase focuses on preparing the land, establishing site infrastructure, and managing logistics before vertical construction begins.
This phase encompasses the design and analysis of all load-bearing elements, structures, and buildings.
Throughout the project lifecycle, the C&S scope requires a series of documented deliverables:
Ensuring that what is built in the field matches the engineered designs:
28 Silos × 47m Height · Al-Meem United Co. · SAR 16.25M · 2013–2015
4,000 m² · 6,500 m² Land · SAR 12M · Al-Kharj · 2025–Present

Comprehensive renovation and interior/exterior fit-out for residential, commercial, and institutional buildings — transforming existing spaces to new standards of quality and functionality.
The scope of work for a fire fighting and interior fit-out system includes the design, procurement, and installation of active/passive fire protection and life safety systems. It guarantees code-compliant integration with the building's architecture, involving sprinklers, fire alarms, suppression, and fire-rated partitions
The breakdown below outlines the core phases and deliverables:

Supply, installation, testing, and commissioning of HVAC equipment and cooling systems for commercial buildings, industrial facilities, residential developments, and mission-critical environments across Saudi Arabia.
SITC stands for Supply, Installation, Testing, and Commissioning. For an HVAC project, this scope of work dictates the end-to-end lifecycle of the system—from procuring the equipment and physical mounting to safety testing, system calibration, and formal handover to the client.
The contractor is responsible for the procurement and delivery of all physical hardware and components to the designated site. Deliverables typically include:
This phase involves all the physical on-site labor and assembly according to manufacturer guidelines and Approved Engineering Drawings:
Once hardware is installed, the contractor must verify structural and functional integrity before turning the system on:
The final operational phase ensures the system meets design specifications and operational efficiency:
