What is the typical HVAC duct package for a major airport terminal?

For a tier-1 international airport terminal at 30-50 million passengers/year capacity, the HVAC duct package is typically USD 80-200 million across passenger terminal, baggage handling, jet bridges, food service, retail and back-of-house. The terminal HVAC package alone is often the largest single mechanical scope outside the chiller plant. Western Sydney Airport (35 mppa target) HVAC duct package is in the AUD 100-150M range; Riyadh King Salman International (120 mppa target) is in the USD 400-600M range; Singapore Changi T5 (50 mppa) is in the SGD 200-300M range.

Are SBKJ machines used for fire-rated stairwell pressurisation duct?

Pressurisation duct for fire-rated stairwells, lift shafts and refuge areas requires SMACNA Class A leakage compliance plus fire integrity rating (typically 2-hour for Class A stairwells per IBC/IFC, equivalent in NCC Section C for Australia). SBKJ's SBAL-V auto duct line produces ductwork to SMACNA Class A leakage with TDF flange. The fire integrity rating is achieved by external insulation systems (mineral wool wrap with calcium silicate at penetrations) installed by the buyer's mechanical contractor; SBKJ supplies the duct, not the fire wrap. Pressurisation fans must carry their own fire rating per AS 4391 or equivalent.

How does jet bridge HVAC differ from terminal HVAC?

Each jet bridge typically has a dedicated AHU (air handling unit) sized 5,000-15,000 cfm depending on bridge length, providing positive pressure to prevent infiltration of jet fuel exhaust and ramp temperature variation. Bridge HVAC duct is short (10-30 m) but requires fire damper at the terminal interface. Materials: galvanised G90 standard; 316L stainless preferred for tropical/coastal airports (Singapore, Hong Kong, Brisbane, Cairns) due to humidity-driven corrosion. SBKJ machinery is used by jet bridge OEMs (FMT, ThyssenKrupp Airport, AERAS, JBT) for the bridge-side ductwork.

What are the smoke management requirements for atriums and large terminals?

NFPA 92 (Standard for Smoke Control Systems) is the dominant US/global standard for atrium and large-volume smoke management. Key requirements: smoke layer maintained at minimum 2.5 m above the highest occupant walking surface during fire emergency, mechanical exhaust sized for design fire heat release rate (typical 2-5 MW for retail atrium, 5-10 MW for terminal concourse), make-up air at lower velocity than exhaust to avoid disturbing smoke layer. Australian equivalent: AS 1668.4 with NCC Section E2. SBKJ's SBAL-V auto duct line produces SMACNA Class A leakage smoke management ductwork; smoke control fans must be rated for high-temperature operation (250°C for 2 hours typical per EN 12101-3).

What about MRO aircraft hangar HVAC?

Aircraft Maintenance Repair and Overhaul (MRO) hangars are the largest single-volume HVAC environments at any airport: a wide-body MRO hangar is 40,000-80,000 m³ with cooling load 800-1,500 kW. HVAC challenges: hangar door air curtain at 300-1,000 m³/s to prevent terminal air loss, dedicated jet fuel exhaust during fueling per NFPA 415 zone classification, paint booth integration for corrosion repair, ATEX/IECEx zoning if open fueling, fire suppression system coordination per NFPA 410. Materials: heavy-gauge galvanised G275, with 316L stainless for paint booth exhaust. SBKJ's SBAL-V auto duct line and SBTF spiral tubeformer are typical MRO hangar HVAC fabrication equipment.

How does climate affect airport HVAC design?

Tropical and coastal airports (Singapore Changi, Hong Kong, Bangkok, Cairns, Brisbane, Manila, Mumbai, Dubai DWC) prioritise dehumidification capacity, 316L stainless duct for corrosion resistance to coastal salt aerosol, and frequent filter change-out. Hot dry airports (Riyadh, Abu Dhabi, Dubai DXB, Phoenix, Las Vegas, Adelaide) prioritise high cooling capacity at extreme outside-air temperatures (45-50°C peak). Cold airports (Toronto Pearson, Helsinki, Stockholm, Oslo, Anchorage) prioritise heat recovery from exhaust and freeze protection on outside air. Mid-latitude airports (Melbourne, Sydney, Christchurch, Tokyo, Seoul, Frankfurt, London) have economiser-cycle-friendly climates allowing free cooling overnight.

What is the construction timeline for airport HVAC?

Major airport terminal construction is typically 3-5 years from groundbreak to commissioning. HVAC fitout commences after building shell-and-core (typically 18-24 months in) and runs through commissioning (final 12-18 months). HVAC duct manufacturing occurs in parallel with fitout, with the SBKJ-equipped fabricator typically running multi-shift operation for 12-24 months continuous to deliver the duct package. Plan SBKJ machinery procurement at least 12 months before the fabricator is awarded the airport package contract.

Airport HVAC at a glance

Airports are among the largest single-site HVAC projects in the world. A tier-1 international terminal at 30-50 million passengers/year capacity carries an HVAC duct package of USD 80-200 million across passenger terminal, baggage handling, jet bridges, food service, retail and back-of-house. Larger projects exceed this: Riyadh King Salman International (120 mppa target) is USD 400-600M HVAC duct alone; the new Western Sydney International Airport (Nancy-Bird Walton, AUD 5.3B+ total) carries an AUD 100-150M HVAC duct package across the terminal and supporting buildings.

SBKJ machinery is the standard fabrication equipment for these airport duct packages. SBAL-V auto duct lines run multi-shift for 12-24 months continuous to deliver the volume; SBTF spiral tubeformers handle round duct for retail, atrium and concourse. TDF flange formers achieve the SMACNA Class A leakage performance required for stairwell pressurisation and atrium smoke management.
