CONSTRUCTION
Supporting safe, efficient delivery throughout the construction phase.
Ensuring systems are installed and energised to the highest industry standards.
Construction
S.A.S Transition, construction is where expertise meets precision. We deliver electrical and mechanical builds that form the foundation of modern infrastructure - from data centres and renewable facilities to oil and gas, nuclear, and grid projects.
Our teams bring decades of field experience across HV/LV electrical and mechanical installations, including system design, switchgear assembly, containment and cabling, transformer works, chilled water systems, pumps, and HVAC plant. Every project is driven by control, coordination, and safety - executed under Safe Systems of Work (SSoW), COHE/LOTO, and rigorous QA/QC inspection and documentation to ensure full compliance and reliability.
Through our digital platform, SASTpro, we manage documentation, permits, and progress tracking in real time - ensuring the same consistency and quality across every site. From design to delivery, S.A.S Transition provides the knowledge, structure, and reliability needed to build safely in today's demanding environments.
