Core Contracting Services (CCS)
SAS Core Constructions Co. LLC.
SAS Core Constructions Co. is a leading multidisciplinary contracting company providing integrated solutions across the Oil & Gas, Petrochemical, Power, Water, and Infrastructure sectors in the Kingdom of Saudi Arabia. We specialize in mechanical, civil, and electro-mechanical works, offering end-to-end project support — from fabrication and installation to testing, commissioning, and maintenance.
Piping Fabrication & Erection (CS, SS, Alloy, GRE, HDPE)
Piping fabrication involves precision cutting, welding, bending, and assembly of materials like CS, SS, Alloy, GRE, and HDPE as per design and international standards. Each material requires specific techniques—metal pipes need certified welding and NDT, while GRE and HDPE use lamination or butt-fusion methods. Strict quality checks ensure durability, safety, and long-term performance of the piping system.
Piping erection includes lifting, positioning, and installing prefabricated spools, fittings, valves, and supports at site locations. Proper alignment, torqueing, and leveling guarantee smooth flow and operational efficiency. The process is followed by hydrotesting or pneumatic testing, flushing, and commissioning to verify system integrity. Skilled manpower and systematic planning ensure safe, reliable, and timely project completion.
Pipeline Construction (Oil & Gas, Industrial, Utility)
Pipeline construction involves surveying, trenching, stringing, welding, coating, and lowering-in of pipelines for Oil & Gas, Industrial, and Utility applications. Each stage follows strict safety and quality standards to ensure leak-free and durable operation. Advanced welding, radiography, and coating techniques are applied to protect pipelines from corrosion and environmental impact.
The construction process continues with backfilling, hydrotesting, pigging, and commissioning to confirm the pipeline’s strength, alignment, and operational readiness. Skilled teams coordinate equipment, right-of-way management, and environmental compliance to complete projects efficiently. Proper execution ensures reliable transportation of oil, gas, water, and industrial fluids across long distances.
Tank Fabrication & Erection (Fixed Roof, Floating Roof, TES Tanks)
Tank fabrication involves plate cutting, rolling, welding, and assembly of fixed roof, floating roof, and TES tanks as per API and project standards. Each tank type requires specific engineering—from precision shell plate alignment to high-quality welds and NDT checks. Corrosion protection, material selection, and strict QA/QC procedures ensure structural strength and long service life.
Tank erection includes constructing the bottom plates, shell courses, roof structures, and internal components at site with controlled sequencing. Mechanical testing, hydrotesting, calibration, and final inspection confirm tank integrity and performance. Proper planning, skilled manpower, and safe lifting practices ensure reliable storage solutions for oil & gas, industrial, and utility applications.
Steel Structure Fabrication & Installation
Steel structure fabrication involves cutting, drilling, welding, and assembling structural components such as beams, columns, trusses, and platforms according to detailed engineering drawings. Precision measurements, certified welding procedures, and strict quality inspections ensure strength, durability, and compliance with international standards. Surface preparation and protective coatings further enhance corrosion resistance for long-term performance.
Installation includes lifting, positioning, and bolting or welding steel members at site using cranes and proper rigging methods. Accurate alignment, grouting, and structural stability checks ensure safe load transfer and overall system integrity. Final inspections, torqueing, and painting are completed before handover, ensuring the structure meets all safety, functional, and architectural requirements.
Mechanical Equipment Erection (Pumps, Compressors, Heat Exchangers, Skids)
Mechanical equipment erection involves receiving, inspecting, and preparing pumps, compressors, heat exchangers, and skids for installation as per engineering specifications. The process includes base preparation, leveling, grouting, and precise alignment using laser tools to ensure smooth and vibration-free operation. Strict adherence to QA/QC procedures and manufacturer guidelines ensures reliability and long-term performance.
Field installation includes coupling alignment, piping hook-ups, electrical and instrumentation connections, and functional checks. Each piece of equipment undergoes pre-commissioning tests such as rotation checks, lubrication, pressure tests, and performance verification. Skilled handling, safe lifting practices, and systematic documentation ensure efficient installation and trouble-free commissioning of mechanical systems.
