Engineering Services
Three integrated disciplines. One accountable partner. TriAxis delivers mechanical and controls engineering from initial design review through commissioning, handover, and long-term maintenance.
HVAC Systems
Mechanical engineering from design review through performance verification.
TriAxis provides full-scope HVAC engineering for commercial, institutional, and government facilities across the Kingdom. Our involvement begins at design review stage — identifying specification gaps, equipment selection issues, and coordination conflicts before they become site problems.
Design Review & Specification
Critical review of mechanical drawings, equipment schedules, and specifications. We identify design gaps, coordination conflicts, and compliance issues before procurement.
Equipment Selection & Procurement Support
Technical evaluation of HVAC equipment submittals — chillers, AHUs, FCUs, VRF systems, and associated controls — against project specification and local climate conditions.
Installation Supervision
On-site technical oversight of mechanical installation to ensure compliance with approved drawings, manufacturer requirements, and project quality standards.
System Testing & Balancing
Air and water balancing, duct leakage testing, and equipment performance verification against design parameters.
Commissioning
Structured commissioning process covering pre-functional checks, functional performance testing, and integrated systems testing with BMS controls.
Handover & Documentation
Complete O&M documentation package, as-built drawings, commissioning records, and warranty registration for client handover.
Building Management Systems
Controls engineering from specification to operator independence.
TriAxis delivers the full BMS scope — not just installation. We design the controls architecture, integrate equipment from multiple vendors across open and proprietary protocols, build operator graphics that facility teams can actually use, and train the client's own staff to run the system without ongoing contractor dependency.
Controls Design
Sequence of operations, control schematics, I/O schedules, and points lists developed from mechanical specifications. We write the controls logic, not just implement someone else's.
System Architecture
Network topology design, controller selection, field device specification, and integration strategy across HVAC, fire, access control, lighting, and energy metering systems.
Multi-vendor Integration
Protocol-agnostic integration across BACnet, Modbus, KNX, LON, and proprietary systems. We connect equipment from different manufacturers into a single coherent management platform.
Operator Graphics
SCADA-level graphical interfaces built for the facility operations team — intuitive floor plan navigation, equipment status, alarm management, and trend logging. Designed for daily use, not just commissioning.
Commissioning & Verification
Point-by-point verification, sequence of operations testing, alarm and interlock testing, and integrated systems commissioning with HVAC and other building services.
Client Team Training
Structured training programme for the facility management team — system navigation, alarm response, scheduling, trend analysis, and routine maintenance tasks. Delivered on-site with the live system.
Integrated Project Management
Coordinated delivery across mechanical and controls scope.
The gap between HVAC and BMS disciplines is where projects lose time, quality, and budget. TriAxis manages both scopes as a single integrated programme — eliminating the coordination failures that arise when mechanical and controls contractors work in isolation.
Programme Planning
Integrated schedule development covering mechanical installation, controls rough-in, BMS programming, testing, and commissioning milestones — sequenced to avoid the conflicts that delay handover.
Procurement Coordination
Technical review of equipment submittals, controls compatibility verification, and long-lead item tracking to keep the programme on schedule.
Quality Management
Inspection and test plans, site quality audits, non-conformance tracking, and resolution — applied consistently across mechanical and controls scope.
Subcontractor Management
Technical oversight and coordination of specialist subcontractors — ensuring scope boundaries are clear, interfaces are managed, and programme commitments are met.
Commissioning Management
End-to-end commissioning programme management — pre-commissioning checklists, resource scheduling, witnessing, defect tracking, and sign-off documentation.
Handover & Closeout
Structured handover process including O&M documentation, as-built drawings, training coordination, warranty registration, and post-handover support period.
Maintenance Contracts
Ongoing technical support once the building is live.
TriAxis stays on after handover. Our maintenance contracts cover planned preventive maintenance for HVAC systems, BMS software updates and calibration, fault response, and ongoing operator support — delivered by the same team that commissioned the system.
