Why Singapore in 2026
Singapore is small but high-value. The HVAC duct market is dominated by sophisticated MEP contractors serving high-end commercial, hyperscale data centre, semiconductor, pharma and biotech projects. Singapore's land scarcity and high labour cost create a unique supply chain pattern — many Singapore-based HVAC contractors source duct from Malaysian (Johor) or Indonesian (Batam) fabricators and add value through engineering, project management and on-site installation in Singapore.
Standards and codes
- SS 553 — Code of Practice for Air-conditioning and Mechanical Ventilation in Buildings
- SS 530 — Code of Practice for Energy Efficiency Standard
- BCA Green Mark — mandatory green building certification
- SCDF Fire Code — fire safety requirements for HVAC
- SMACNA — dominant on hyperscale, international hospitality, FDI
- ASHRAE 90.1, 62.1 — widely referenced
- BCA Code on Mechanical Ventilation — mechanical ventilation requirements
2026 demand drivers
- Hyperscale data centre: post-moratorium DC-CFA awarded capacity to AirTrunk, Equinix, GDS, ST Telemedia. New capacity emphasises PUE below 1.3, driving sophisticated HVAC.
- Semiconductor: TSMC, GlobalFoundries, Micron Singapore expansion. ISO 14644 Class 5-6 cleanroom HVAC.
- Pharmaceutical: GSK, Pfizer, Roche, Sanofi expansion in Tuas Biomedical Park.
- Biotech: A*STAR Biopolis, NUS-Duke biomedical research.
- Commercial real estate: CBD redevelopment, Marina Bay completion, growth corridors (Punggol Digital District, Jurong Lake District).
- Hospital: SingHealth and NHG cluster expansion, private hospital growth.
- Hospitality: Marina Bay area refurbishment, Mandai eco-tourism, Sentosa expansion.
- Industrial: Jurong Island chemical and energy expansion.
The Singapore-Johor-Batam supply chain
Most Singapore HVAC contractors don't operate large in-Singapore duct fab shops because of land cost and labour cost. Instead, the typical pattern is:
- Engineering and design in Singapore (high-skill, high-cost activity)
- Duct fabrication in Johor (Malaysia) or Batam (Indonesia FTZ) at significantly lower cost
- Cross-border logistics (truck via Tuas/Woodlands checkpoints to Johor; ferry to Batam)
- Installation in Singapore (high-skill on-site work)
This pattern means Singapore is more of an end-market for HVAC duct than a fabrication base. SBKJ's typical Singapore customer is therefore based in Johor or Batam, supplying Singapore projects. SBKJ has supplied multiple Johor and Batam fabricators serving the Singapore market.
If you do want to fabricate in Singapore
If land is secured and the operation is justified by specific project requirements, options:
- Tuas (heavy industrial): largest industrial zone, port-adjacent. Land lease via JTC Corporation, USD 12-25/sqft/year (USD 130-270/m²/year).
- Jurong industrial parks: established industrial corridor. USD 10-20/sqft/year.
- Woodlands: north industrial, Causeway-adjacent. USD 8-16/sqft/year.
- Changi industrial: smaller footprint, airport proximity.
Singapore equipment capex including freight and customs is approximately USD 580,000-880,000. Plus very high building cost compared to other regions.
Singapore labour cost
- Senior fitter / supervisor: SGD 65,000-95,000/year (USD 50K-72K)
- HVAC fitter (Work Permit holder): SGD 42,000-62,000/year (USD 32K-47K)
- Auto duct line operator: SGD 38,000-58,000/year
- Qualified welder: SGD 50,000-75,000/year
- QA/QC engineer (graduate): SGD 75,000-115,000/year
- Project manager: SGD 110,000-180,000/year
CPF and foreign worker levy add to fully loaded figure. Sector quota for foreign workers limits headcount expansion.

FAQ
What HVAC duct standard applies?
SS 553 baseline; SMACNA dominant on hyperscale/hospitality/FDI; BCA Green Mark mandatory; ASHRAE 90.1/62.1 widely referenced.
What is the data centre moratorium status?
Lifted in 2022. New capacity awarded under DC-CFA scheme to AirTrunk, Equinix, GDS, ST Telemedia. PUE under 1.3 requirement drives sophisticated HVAC.
Where can I locate?
Tuas (heavy industrial), Jurong (industrial parks), Woodlands (Causeway), Changi (airport). All via JTC Corporation. Many fabricators instead operate in Johor or Batam.
What sectors drive demand?
Hyperscale data centre, semiconductor (TSMC, GF, Micron), pharma (GSK/Pfizer/Roche), biotech, commercial RE, hospital, hospitality, industrial (Jurong Island).
What is typical labour cost?
Senior fitter SGD 65-95K, fitter SGD 42-62K, line operator SGD 38-58K, welder SGD 50-75K, QA engineer SGD 75-115K, PM SGD 110-180K. CPF + foreign worker levy add up.
