The power of steel in the multi-storey commercial zone is established on tangible concrete client-related benefits such as the skill to provide column free floor spans, efficient circulation space, influence of the site and integration of building services. For inner city projects on the other hand, steel-framed systems can be given. Because there is a guarantee of speed in construction and the minimum storage needed for materials on-site that need high-level of pre-fabrication.
When it comes to high quality office space most especially in city centres, there is a very strong demand. Banks for example, most especially their corporate headquarters including other high profile companies will need buildings that are high architectural. In addition, they will need buildings that will meet environmental standards. When choosing a building architecture, form and servicing planning, investment value is the main factor. Nowadays, a number of buildings have either complex or curved architectural in form. As for others, they have highly glazed atria and facades.
In abounding large commercial buildings, there is a two stage construction process. It basically means that the tenant is held responsible for contracting and fit-out. As such, the structure of the building has to be flexible enough to make go of the differing necessities. As for small buildings, natural ventilation is designed with renewable energy technologies attached to them. After all, by using steel construction, there are many possible solutions.
Due to the rise of our business and economy, the commercial market calls for buildings that are very quick to construct. They also need adaptable in application, energy efficient to use, flexible and of high quality. Steel frame has it all. It has a composite construction that has reached over 70% market share in the commercial sector. The benefits are definitely for long term: improved quality, integration of service, reduction of environmental impact and speed of construction.
In recent times, cost comparison studies have proven that building super structure overall accounts for only 10-15% of the overall cost of the building. What is even more significant is the impact of choice of structure when it comes to cladding costs, foundations and services. For example, if 100 mm in the ceiling to the floor zone is reduced, it can result to 2.5% saving in cladding cost. That is equals to 0.5% saving in the overall cost of the building.
In that event, the best practice when it comes to building design needs a building an architectural, constructional, logistics, services and structural issues. Once the synthesis has been done, long-span steel systems with an arrangement for service integration will lead commercial building designs.
