In spite of their seeming simpleness, the design of a parking lot on multiple levels-- whether over ground or below-- includes the consideration of a number of significant requirements. Despite their seeming simplicity, the layout of a parking area on several levels-- whether above ground or below-- involves the factor to consider of a variety of considerable demands. These variety from effective flow to architectural issues, criminal activity avoidance as well as health & security facets. The numerous disciplines are reviewed in more detail listed below.
The first factor to consider for the design of a car park is the number of vehicles to be suited, compared to the space available. Expense restrictions for excavation when it comes to underground parking lot, for instance, require to be factored in. Automobile circulation rates will require to be factored in to estimations for the variety of spaces to be offered to fulfill need at peak times in, for instance, a shopping center or hospital. Having developed these fundamental parameters, the primary generator of the design of a car park is the dimension and restrictions of the vehicles that will certainly utilize it. Whilst in the main this will typically be automobiles (and also to some extent motor cycles), bigger vehicles such as fire home appliances or rescues will likewise require to be considered. Geometric needs consist of transforming circles, swept paths as well as ramp gradients.
Usage matters that affect the layout consist of settlement techniques like pay machines on vehicle parking decks or in stairway entrance halls, or pay-by-phone and also moratorium enabled after payment, before automobile leave if pay-on-exit is picked. Multi floor parking lot are essentially primary structure frameworks, albeit with certain specific efficiency requirements that need to be satisfied. The total architectural kind will be greatly influenced by the layout geometry embraced. Below ground car parks will, to a big extent, be figured out by the framework over like a multi floor building or a public yard.
The architectural structure can be either reinforced concrete (precast systems or cast in-situ), steel or a composite structure (steel light beams and columns, supporting concrete flooring slabs). Ribbed or coffered slabs are frequently made use of. Lightweight-aggregate concrete can minimize overall loadings dramatically, and also has much better fire performance. Concrete should be developed to be durable against chemical corrosion attack. Non-slip surfaces in particular to ramps are likewise prudent, to avoid skidding. Heated frameworks are likewise possible, although their efficiency can be questionable.
Wind lots as well as resonance additionally need to be thought about. Architectural resistance to explosions (over fire resistance) must additionally be thought about. Underground car parks will certainly require comprehensive retaining wall style, integrating tanking and land drain. Parking area make use of impulse air flow to remove carbon monoxide and also various other contaminants from deep-plan parking decks. This employs a number of little, high rate followers in lieu of conventional ductwork, operating on the tunnel air flow concept to route airflow towards the main remove follower intake factors. Sound control needs to be taken into consideration for air handling plant in noise-sensitive locations, or to follow Regional Authority bylaws or intending policies.
All surface water in parking area has to be passed through a gasoline interceptor before discharging to the major drainage system. A complete emergency illumination system will be needed, with backup supplies. This remains in addition to a fire discovery and also alarm system, potentially with sprinklers where a fire-engineered layout car parking barriers is required, although factor to consider should be provided to the selection as well as area of fire suppressant used, where automobile gas or electric fires are a high danger.
Consideration should be provided to the arrangement of electric charging points for hybrid or electrical autos. Underfloor heating is sometimes used, in particular on vehicle ramps to stop skidding, although its effectiveness can be suspicious.
