ACMV &
HVAC
Systems

As a licensed ACMV contractor in Singapore, Winsteam provides the full lifecycle of Air Conditioning and Mechanical Ventilation services — from initial design through to long-term operation and maintenance.

We work with all major chilled water system configurations, handle both central plant and distributed ACMV architectures, and deliver SS 553-compliant commissioning with complete documentation at handover.

All ACMV works comply with BCA regulations, SS 553 (Code of Practice for Air-Conditioning and Mechanical Ventilation in Buildings), SS 554 (Code of Practice for Indoor Air Quality in Air-Conditioned Buildings), and SCDF requirements.

ACMV Design & EngineeringCooling load calculations, equipment selection, BCA submission drawings, and M&E coordination for new and retrofit projects.
Chilled Water Plant InstallationChillers, cooling towers, primary and secondary pumping systems, and full pipework for central ACMV systems.
AHU & FCU WorksSupply, installation, and commissioning of air handling units and fan coil units across all facility types.
ACMV Retrofit & UpgradingEnergy-efficient replacement of ageing systems including refrigerant conversion, VSD retrofits, and SS 553 compliance upgrading.
BMS IntegrationACMV controls and building management system integration for centralised monitoring, scheduling, and energy optimisation.

MEP
Engineering

Winsteam provides integrated MEP (Mechanical, Electrical, and Plumbing) engineering for buildings across Singapore. Our in-house capability across all three disciplines means one contractor manages your complete building services scope — eliminating the interface risk, cost duplication, and coordination overhead of managing separate mechanical, electrical, and plumbing contractors.

We handle everything from M&E design and BCA submission through to installation, testing, commissioning, and handover documentation. See our guide on choosing an M&E contractor in Singapore for how this scope compares to an ACMV-only engagement.

Mechanical SystemsACMV and plumbing — chilled water, domestic water supply, drainage, and sanitary systems.
Electrical SystemsLV distribution, lighting design, power outlet planning, and earthing for commercial and industrial buildings.
Fire ProtectionSprinkler systems, fire suppression, wet risers, and coordination with SCDF requirements.
Controls & BMSBuilding management system design and integration — ACMV controls, energy metering, and building automation.
M&E CoordinationFull coordination with architectural, structural, and specialist teams — clash detection and shop drawing review.

Cleanroom
Design &
Validation

Winsteam designs, builds, and validates cleanrooms to ISO 14644 standards for pharmaceutical manufacturing, semiconductor production, medical device assembly, and laboratory environments across Singapore.

Our cleanroom scope covers the ACMV infrastructure (HEPA filtration, pressurisation, temperature and humidity control), the physical envelope (walls, ceilings, floors, airlocks), environmental monitoring systems, and full validation documentation — IQ, OQ, and PQ protocols aligned to GMP requirements.

Single-point accountability from design through validated handover.

Cleanroom ACMV DesignHEPA and ULPA filtration, unidirectional and turbulent flow systems, pressurisation cascades, and temperature and humidity control to ISO 14644 specifications.
Cleanroom ConstructionCleanroom envelope installation — sandwich panel walls and ceilings, epoxy or vinyl flooring, pass-throughs, and airlocks.
Environmental Monitoring SystemsParticle counters, temperature and humidity sensors, differential pressure monitoring, and integration with BMS or dedicated EMS platforms.
Validation (IQ/OQ/PQ)Installation qualification, operational qualification, and performance qualification documentation for GMP-regulated cleanroom environments.

Winsteam offers design, supply, installation, commissioning, retrofit, and preventive maintenance of ACMV and HVAC systems. This covers chilled water plants, AHUs, FCUs, ductwork, BMS integration, and SS 553-compliant testing and commissioning. We serve hotels, hospitals, data centres, commercial offices, industrial facilities, and pharmaceutical cleanrooms.
Yes. Winsteam provides integrated MEP services covering mechanical (ACMV and plumbing), electrical (LV distribution, lighting), fire protection, BMS and controls integration, and full M&E coordination. Single-point accountability across all building services disciplines reduces interface risk and project complexity.
Winsteam designs and builds ISO Class 5 through ISO Class 8 cleanrooms for pharmaceutical GMP, semiconductor, medical devices, and biotech R&D environments. Scope covers ACMV infrastructure (HEPA filtration, pressurisation, temperature and humidity control), cleanroom envelope, environmental monitoring systems, and full IQ/OQ/PQ validation documentation.
We tailor each PPM contract to your facility's equipment inventory and operational requirements — agreeing a maintenance schedule (monthly, quarterly, bi-annual, and annual visits), assigning a dedicated service team, and providing compliance reporting at each visit. Contracts include 24/7 emergency call-out response for hotels, data centres, hospitals, and pharmaceutical facilities.
Yes. The majority of our retrofit and maintenance work is carried out in occupied or partially occupied buildings — hotels, hospitals, and commercial offices that cannot shut down. We plan phased works carefully, schedule intrusive activities during low-occupancy periods, and coordinate closely with facilities teams to minimise disruption.
