Regardless of their seeming simpleness, the layout of a car park on several levels-- whether above ground or below-- involves the consideration of a number of considerable needs. In spite of their seeming simplicity, the design of a parking lot on numerous degrees-- whether above ground or below-- includes the factor to consider of a number of considerable demands. These array from efficient circulation to architectural issues, crime prevention and health and wellness & security aspects. The numerous subject areas are talked about in even more detail below.
The initial consideration for the format of a car park is the variety of lorries to be fit, compared with the room car parking barriers available. Cost constraints for excavation in the case of below ground car parks, as an example, need to be factored in. Car flow rates will need to be factored in to computations for the number of rooms to be supplied to fulfill demand at peak times in, as an example, a mall or medical facility. Having developed these fundamental criteria, the key generator of the format of a parking lot is the dimension and also restrictions of the cars that will utilize it.
Whilst generally this will commonly be cars and trucks (and somewhat electric motor cycles), bigger lorries such as fire home appliances or ambulances will also need to be considered. Geometrical requirements include transforming circles, swept courses as well as ramp gradients.
Usage issues that influence the design consist of settlement methods like pay devices on auto parking decks or in stairway entrance halls, or pay-by-phone and grace periods permitted after repayment, before car departure if pay-on-exit is chosen. Multi storey parking lot are basically elementary structure frameworks, albeit with certain particular performance standards that have to be satisfied. The overall architectural kind will certainly be greatly influenced by the design geometry taken on. Underground parking lot will, to a large degree, be determined by the framework over like a multi storey structure or a public yard.
The structural structure can be either enhanced concrete (precast units or cast in-situ), steel or a composite structure (steel beams as well as columns, supporting concrete floor slabs). Ribbed or coffered slabs are commonly made use of. Lightweight-aggregate concrete can minimize overall loadings considerably, and also has much better fire efficiency. Concrete have to be made to be resilient against chemical rust assault. Non-slip finishes specifically to ramps are additionally sensible, to prevent skidding. Warmed frameworks are likewise feasible, although their effectiveness can be questionable.
Wind tons as well as vibration also need to be taken into consideration. Architectural resistance to surges (over fire resistance) should additionally be thought about. Underground parking lot will certainly require substantial maintaining wall layout, including tanking as well as land water drainage. Parking area use impulse ventilation to remove carbon monoxide and also various other pollutants from deep-plan vehicle parking decks. This employs a variety of little, high velocity followers in lieu of typical ductwork, operating on the tunnel air flow principle to guide air flow in the direction of the major extract fan intake factors. Sound control requires to be taken into consideration for air handling plant in noise-sensitive areas, or to abide by Local Authority bylaws or intending guidelines.
All surface water in parking area has to be passed through a gas interceptor before releasing to the primary drainage system. A complete emergency situation lights system will certainly be required, with back-up supplies. This remains in enhancement to a fire detection and alarm, potentially with sprinklers where a fire-engineered design is needed, although factor to consider needs to be given to the option and location of flame suppressant made use of, where vehicle fuel or electric fires are a high risk.
Factor to consider ought to be provided to the arrangement of electrical charging points for crossbreed or electric cars. Underfloor heating is in some cases used, particularly on automobile ramps to prevent skidding, although its efficiency can be questionable.
