Project Profile

Project One
SIMPARK – Rawdon Street, Kolkata (Completed in November, 2001)
Technology Type Parkomat

We make Calcuttans proud by introducing the "World's First Fully Automatic Mechanized Public Multi-Level Car Parking System on a Curve", at the intersection of Park Street-Rawdon Street crossing, in a Joint Venture with the Kolkata Municipal Corporation. The ground plus two-storied computer based system, accommodates upto three times more than conventional parking. The system at Rawdon Street has been constructed to provide car-parking facility for around 210 cars on a ground area of 1260 Sq. Mtrs. Each row can individually hold on average 73 numbers of cars. The system is operated from both the ends of the structure. Each lift lobby having its own individually control panel and ticketing system. However, one can park and retrieve his/ her car from either end and vice versa. A steel pallet is designated for every car slot in the system. Whenever a car needs to be parked, the ticketing button is pressed and the entrance gate opens only after a pallet has been delivered. The driver parks his car on the pallet, engages a gear, locks his car (optional as nobody can go inside the system and your car is safe as in a vault), and walks out of the system. The tickets to the system is a simple the magnetic strip cards, which the ticket attendant swipes. From herein onwards, the computer takes over. One must remember not to lose the magnetic card as it contains information on the parked vehicle. The beauty of this Parking system is inherent in its intrinsic simplicity. It is a modular Lego like system and therefore can be adapted to fit any size or shape of plot. Each grid has an independent lift and each floor or array of cars has its independent carrier. For every car to be parked in the system, there is a steel pallet designated when a car is to be parked, on a button being punched the entrance gate opens. The driver parks his car on the pallet, engages a gear, locks his car (optional), and walks out of the system. From herein onwards, the computer takes over. Uniquely designed lift, enables carriers to pass through lift shaft, when lift is not in the specific floor. More than one lift can be placed in each row at either end, or in the middle as required.


The PLC system computer decides, which floor, which and slot the pallet with the car is to be placed is to be parked on. Accordingly, the pallet with the car placed on it is taken up with the help of the vertical elevator system to the desired floor. The next step is that on reaching the particular floor the carrier system picking up picks up the pallet along with the car, and moving it horizontally along the structure over the other vehicles to the place assigned by the computer it slowly lowers it into the slot assigned by the system. It should be made quite clear here, that the height of each floor, is a little more than two double the cars height, so that the carrier transports the car above the already parked cars. Retrieval of parked cars is precisely the same operation, but in the reverse order. When the driver comes to collect his car, he gives the ticket/magnetic card, which was given to him on parking. The card is swiped and; automatically the bill for parking is generated for payment. Simultaneously the computer has issued the order for retrieval. Carrier picks up the relevant pallet, transports it over other cars and places it on the elevator. The elevator brings down the pallet. On retrieval retrieval, through a turntable, the pallet takes a turn and keeps the car is in a drive-out position. The Main gates opens automatically, driver walks in and drives out in his carfor the driver to drive out his car. The Gate close automatically and the system is on standby for the next requests. The entire system can operate, with just one ticket attendant in each lobby. In case of the remote eventuality of any problem, the same shall be reflected immediately in the master computer in the control room and the fault rectified within minutes.

  1. Night parking.
  2. Multiple Entry and Exit facilities.
  3. Provision for long term booking of parking slots.
  4. ATM and Vending Machine.
  5. Public Call Booth.
  6. Front / Backlit show windows for corporate and product advertising


We have used RCC grid of Concrete Column and Beam only for the parking tower. There are no slabs for the parking tower. Top Roof is done with coated G.I. Sheets simply supported by Crush Structures. The structure has been designed for required dead load & lift load as per I.S. Standard. Necessary construction instructions as per I.S. Construction have been provided. Elevators have been placed at both the end of the structures. The Control Panel with P.L.Cs will control the movement of the elevator and Electronic devices. Fire fighting with sprinklers system has been provided. The fire fighting system has been divided into various zones. Wet risers have also been provided. Other details have been met as per fire laws and by-laws. Round the clock, security cameras have been provided for recording the vehicles entering and exiting the system. These security cameras would also be utilized for recording the movement of people in the entire compound.
