Safety and Security
Small columns, bright finishes, long spans, relatively flat ceilings, and braced or moment frames make a steel-framed parking structure easier to illuminate and secure. This sense of openness, particularly in walkways, creates a positive feeling of passive security. Users often comment on how "open and bright" the decks of a steel-framed garage are. In contrast, concrete structures often require solid interior sheer walls in order to resist lateral (horizontal) loads, which create visual obstructions and a "closed-in" feeling.

Reduced Foundation Requirements
A steel structure can weigh up to one-quarter less than a concrete structure, often an important factor in controlling seismic design, foundation and erection cost, and construction schedule. This weight-saving can allow steel-framed parking structures to be built economically even in areas with marginal soil conditions.

Simplified Maintenance Procedures
Exposed beams, girders and columns permit direct inspection, evaluation, accessibility of the frame and ease of maintenance of steel surfaces. Localized breakdown of a coating system on a steel beam is a good indication of a developing problem with the concrete deck above, such as water or chlorides (road salts) leaking through a crack or a joint. Early detection of deck leakage permits timely corrective measures to be implemented. The "sacrificial" aspect of most concrete decks on steel beams means that major deck repair and rehabilitation can be accomplished with minimum disruption and cost. Many state bridge departments appreciate steel structure for this reason.


Ease of Expansion and Conversion
Structural steel simplifies future expansion or the conversion of a parking structure to a different use. Designing for future vertical expansion is a desired feature for many new parking structures. Vertical expansion can be easily accomplished in a steel-framed structure through the splicing of existing columns and the placement of steel members with readily available cranes. In most cases, only the top level of the existing parking structure needs to be taken out of service. The rest of the garage can remain open. Steel framing facilitates the incorporation of tenant space in occupied lower levels or in occupied space above. The ability to penetrate, weld, bolt and reinforce structural steel in the field makes even unanticipated changes and retrofit practical.

In the construction of multi-storey car parks, the idea of profitability is essential and covers a number of aspects. Steel construction makes it possible to:
1-  Reduce construction costs
2-  Optimise the occupation of the car park
3-  improve return on investment by gaining           floor area (in m2)

Reduced Maintenance Costs
Life-cycle cost is the average annual maintenance and repair costs to be expected over the life of the parking garage. Structural engineers and others who have studied life-cycle costs conclude that steel-framed structures are usually less expensive (J. Englot, and Davidson, R.; "Steel-Framed Parking Garages Take Off at JFK and Newark International Airports," Modern Steel Construction, April 2001). Parking industry experts have indicated that over a 50-year life, the cost to maintain a precast concrete deck and frame system will be between 5 cents and 8 cents per square foot, while the cost to maintain a post-tensioned deck on a steel frame will be between 3 cents and 5 cents per square foot -- a savings of 40 percent. High-performance coatings (paints), galvanizing and metalizing systems are demonstrating superior long-term corrosion protection for exposed structural steel. If deterioration of the concrete deck itself occurs, a steel frame supporting that deck will minimize the cost and time required for rehabilitation of the slab, and may even save the facility from demolition and total reconstruction.
