A steel construction offers perspective on various cost savings in all ‘ life stages ‘ of the building: design, production, external construction, masonry, outfitting, use and reuse. These savings are often with each other or result from each other.
An integral, foresight on cost of a construction can therefore generate a lot of revenue. Some direct and indirect economic plus points in a row.
Save on the number of kilos of steel for the construction does not always the most favourable price. Governs the price include simple links and a limited number of construction elements (rehearsal). This has a major impact on the cost of manufacturing and Assembly.
Prefabrication and Assembly
The lion’s share of the structural work cost consists of implementation costs (manufacturing, assembling and finishing); that is so at each construction. At the steel construction includes mounting costs – and thus the total shell construction costs – the more extensive prefabrication of the structural parts. Also the finish and fire-resistant coating (plate, plaster, paint) can in many cases be applied in the factory.
What remains is a fast, dry Assembly on the construction site. The direct and indirect savings on installation costs: less labour hours, less travel expenses, no delay by unworkable weather, less transport, limited faucet commitment and no expensive auxiliary constructions such as scaffolding and formwork.
By the low weight of the steel structure is to be sufficient with a lighter Foundation. At a standard triple Office is the saving on Foundation costs about 10 – 15%.
The use of steel with higher strength lowers in general the construction weight significantly. Any additional cost for high-strength steel is more than offset by the revenues of the lighter weight, lower transport and Assembly costs (crane equipment, material storage, staff commitment, help).
And steel is in the advantage when building on bad surfaces or on tight, inner-city locations by the combination of light weight and convenient format of the structural parts.
Short construction time
The high construction speed at steel results in savings on time-related costs. At proper alignment on the reduction expires the facade mounting easier with the dimensional stability of the steel construction.
Piping integration is a good example of integral on costs. At floor concepts with integrated beams or girders raat and cells is uninterrupted lines gradient achievable. As a result, savings on installation costs and possibly subsequent reclassification or renovation costs. In addition, the floor concepts ‘ constructive ‘ plus points.
At integrated beams is a lower verdiepinghoogte possible. This makes more floors and thus more net square meters of floor space to be built within the same building height. Especially at higher buildings gives that a major cost advantage. At constant verdiepinghoogte is such a 1-3% saving on the total construction costs (including outfitting, fitted and installations)
The steel construction lends itself to multiple users and multiple functions. Outfitting (facades) and installation (interior walls) of the structure shall be enforceable in all conceivable materials.
Even just before the delivery is to change the layout without the construction to slow down and increase the construction costs. So are floor boards to remove at any time, for example to create voids or an additional staircase. You can, if the floors are not an integral part of the main supporting structure: they do not work as rigid disk.
Changes to facades, walls and plants during design or implementation are also in a cost effective manner after 20 or 30 years of use. The building is without in-depth investment to prepare for other use or a new feature, whereby the economic life of the building is extended. And that will save society the necessary costs for the environment.
