Underground and Multi-Storey Car Park Engineering
For municipalities and investors, we design the structure, electrical and mechanical systems of underground and multi-storey car parks together with the squares, cultural centres or facilities built above them.

Overview
Key issues in car-park design
Underground car parks must resolve soil and water pressure, long spans, fire and smoke safety and heavy traffic at the same time. Often a public square, cultural centre or social facility sits on top, so the structure is designed to carry those loads too.
On the mechanical side, jet-fan ventilation, smoke extraction, sprinklers and hose reels; on the electrical side, lighting, emergency systems, CO detection and car-park management all need to be designed together.
- Basement structure compatible with waterproofing and shoring
- Slabs designed for squares or buildings above
- Jet-fan ventilation and smoke-extraction calculations
- Fire, CO detection, emergency lighting and wayfinding

From our portfolio
Our car-park portfolio includes Galataport Karaköy Underground Car Park, Gedikpaşa Multi-Storey Car Park, Beşiktaş Youth Centre and Underground Car Park, Esenler Wedding Hall and Car Park, Eyüp Çırçır Neighbourhood Hall and Underground Car Park, GOP Underground Car Park, Sultangazi City Square Car Park, Çekmeköy Cultural Centre and Underground Car Park, and Şirinevler Underground Car Park.
In most of these, we treated the car park and the cultural centre, youth centre or city square above it as one engineering system.

FAQ
Frequently asked questions
Which disciplines does an underground car park need?
Structural, mechanical (ventilation, smoke extraction, fire suppression, drainage) and electrical (lighting, emergency, CO and fire detection) design — delivered by one team with BIM coordination.
Why are jet fans used in car parks?
Jet fans provide ductless ventilation, pushing exhaust gases and, in a fire, smoke towards extraction points. Fewer ducts mean lower floor-to-floor heights.
Can a square or building be built on top of a car park?
Yes. The structure is designed for those loads from the start; in our Çekmeköy, Beşiktaş and Eyüp projects, cultural and social facilities sit above the car park.
Do you work on municipal car-park projects?
Yes, we have provided engineering for many municipal and public car parks in Istanbul.
