What the Client wants?
How steel helps to achieve this:
Value for Money
|AN ECONOMIC CONSTRUCTION
- Increased productivity in steel manufacture and
design, fabrication and erection have made steel a low cost way of
- New low cost approaches to fire and corrosion
protection are available.
- Costs have fallen in real terms
CONTINUOUS DEVELOPMENT IN TECHNOLOGY
- By investment in IT and CAD/CAM technology for
engineering and production
A SHORT CONSTRUCTION PERIOD
- Earlier possession of the building for use or rent.
- Lower financing costs
- Better site utilisation
- Earlier access for following trades
SAVINGS THROUGHOUT THE WHOLE PROJECT
- Early involvement of the steelwork contractor in the
- Large unsupported spans
- Smaller site footprint
- A durable form of construction which meets the
building life requirements
- Slender columns resulting in maximising floor area.
- An excellent strength to weight ratio so lower
- Offsite fabrication and lower site costs during
- Prefabricated therefore greater independence from the
- Low cost and efficient approaches to fire protection
- Easy integration of services
- Great flexibility in accommodating changes to the
- IT and software.
- Steel's excellent strength to weight ratio creates an
attractive and economic use of space when beams and columns have small
- New rolled and prefabricated section shapes.
- Economic methods for shaping and curving.
- Standardised solutions for floor systems and
- Opportunities to integrate large openings, for doors
- Fire engineering.
- Complementary structural components can easily be
accommodated curtain walling readily and efficiently connected to the
structure, and other modularised elements such as toilet pods,
dry-casing, M&E items easily fitted.
- Easy adaptation - during the construction period the
client may wish to alter installations and this can readily and rapidly
- Steelwork connections, particularly bolted ones, can
easily be released or re-made in whatever form necessary.
- The client may need to extend, to change the use of
the building, to absorb changes in loading requirements, and to
incorporate new installations.
- Should an increase in loading requirements occur,
then the structural elements can easily be individually strengthened,
or additional members introduced or altered to suit.
- Steel's relative lightness in weight allows
adaptation in the future to be easily accomplished.
- New connections can easily be introduced by bolting
or welding enabling alterations for services or changes of use.
- The construction preparatory phase enables the
structure to be planned and connections to be selected for speed of
- Just-in-Time manufacturing techniques.
- The steel frame is designed and manufactured from
computer models directly linked to the CNC machines thus ensuring high
dimensional accuracy and speed of erection.
- Quick drying coatings technologies.
SHORT CONSTRUCTION PERIOD
- Economical foundations - steel's excellent strength
to weight qualities result in small foundations which then take minimum
time to construct.
- Off-site manufactured elements - ready for immediate
erection upon arrival on site, with no subsequent delays. This means
following trades can carry out their work in parallel.
- New erection techniques, eg use of mobile working
|DURING DESIGN AND FABRICATION
- Extensive research and development by the steel
construction industry into accident prevention.
- Wide ranging Health and Safety guidance documents and
- Off-site manufacture means less site activity.
- Regulatory monitoring of machinery.
- Risk assessments.
- Use of mobile elevating working platforms.
Quality and Reliability
|DURING THE DESIGN PROCESS
- World Class companies using tried and tested
- Steel is a homogenous material and is subject to
documented quality control procedures during manufacture and rolling.
The Client can be assured of obtaining reliable and constant quality.
- A wide range of section shapes and sizes in a range
of qualities offers the most efficient and economic solution for the
- Successful use of IT.
- A qualified and trained workforce - in the
fabrication shops staff are permanently employed, often for the whole
of their working lives, and on site erection companies maintain a
permanently employed labour force.
- Independent Certification of in-house quality systems
gives ongoing assurance of procedures and products.
- Improved coatings technologies.
- High quality surface finishes available for pre-site
- Bolted and welded connections are generally exposed
and therefore are simple to check for quality and safety.
RELATING TO COSTS
- Costs are predictable, which helps with a meaningful
calculation of the investment and risk involved in the project.
- The steel frame is visible for ongoing inspection.
- The plastic behaviour of steel provides additional
security in extreme loading situations, such as explosion, impact,
terrorist attack and earthquake.
|COMPETENT AND RESPONSIBLE CONTRACTORS
- The steel construction industry can give assistance
to the client and his professional team with technical and budgetary
advice at the planning stage of the project.
- Industry standard details in design and connections
offer economy in construction.
- Full design can be carried out where required by the
- Greater co-operation within the project team through
partnering and the consequent improved payment profile result in
benefits for all.
ADVICE AND SUPPORT
- The industry's advisory organisations can help the
client and his team on all aspects of the design, costing, procurement,
fabrication and erection process.
- The Register of Qualified Steelwork Contractors
enables clients to select independently audited companies appropriate
to the project.
- The National Structural Steelwork Specification can
be relied upon to provide industry accepted standards.
- Continual R&D in areas such as fire design,
seismic resistance, health and safety, etc provide the client with safe
structures and a dynamic industry.
INTEGRATED ELECTRONIC TRANSFER OF INFORMATION
- The industry uses software for all aspects of its
processes and engineering modelling tools enable the client and his
professional team to interface directly with the steelwork contractor.
|AT THE CONSTRUCTION STAGE
- Delivery of steelwork is relatively straightforward -
requiring little space, time or inconvenience. The hours of delivery
can be selected in order to reduce public nuisance.
- Because steelwork comprises prefabricated elements,
there is as a result less site disruption with adjoining properties.
- Construction equipment normally used to erect
steelwork is cranes and mobile platforms. These by their nature require
little permanent or temporary space to operate.
- Noise when manufacturing, delivering or erecting
steelwork is not a major problem.
- The speed of steelwork erection means inconvenience
caused is reduced to a minimum period.
- Steel can be easily maintained so that colour and
appearance can always be made to suit a constant or changing
Coatings developed through new technology last longer.
- Steel is basically a clean, user-friendly material -
no dust, no spillage, little waste etc - and consequently no equipment
employed to counteract such problems.
- Steel can be reused, relocated or recycled once its
use has been overtaken by events. Use is therefore responsible in
Steel by its very nature has:
- Clean lines
- Large spanning
- Architectural possibilities
- It appeals to the client and his designer in terms of
attractiveness as well as economy.
- Colour, through paint, can easily and economically
transform a building to satisfy the designer's options.
A STRUCTURE THAT REFLECTS THE CLIENT'S AMBITIONS
- Steel has exhibited consistently great architectural
beauty - suspension bridges, tall towers and high buildings, for
example, the world over are magnets for tourism. Many steel structures
worldwide are viewed as amongst the greatest achievements of mankind.
