INTRODUCTION

MATERIALS AND CONSTRUCTION SYSTEMS

The two world leaders of the building industry are reinforced concrete and steel. Market analysis of the last decade points out that the use of steel has been increasing progressively so as to nearly double its quota of application.

Although reinforced concrete will necessarily remain a leader in specialized applications, the use of new planning techniques will further increment the development and adoption of steel. The general attributes of steel render it capable of supporting the evolution and modernization which the building industry is undergoing.

Construction methods may be divided into two major categories:

– Construction methods using wet materials;

– Construction methods using dry materials.

Reinforced concrete makes use of wet materials. Steel is a dry-material method.

 

STEEL IS INTELLIGENT, COMPETITIVE AND COST–EFFECTIVE

By using steel, it is possible to actualize light, efficient, robust constructions.

It is already possible to execute well-performing structures at significantly reduced cost through traditional building methods. As these structures are industrial products, steel structures are subject to rigid quality controls for certification. Successive stages of assemblage are executed by means of the dry method.

This procedure guarantees perfect compatibility between the project and the completed work. Notwithstanding what may occur in constructions employing the wet method, use of the dry method eliminates the risk of human error/miscalculation.

Dry construction  makes  possible the  development of ulterior  “dry-completion” methods. Dry construction also facilitates the execution of technically better structures, at economic advantage. The professional “know – how” to be employed in this method is easy to acquire, mostly because assemblage techniques, rather than production techniques, are used. The professional training of operating personnel takes place rapidly, yielding immediate learning results.

This would be different were it necessary to retrain building craftsmen: plasterers, cement workers, carpenters. They would need long years of practice to acquire the necessary experience.

The same can be said of the creation of production chains.

 

MAJOR WORKS AND INFRASTRUCTURES

Faced by the growing needs of a society in progressive evolution, the sector of major works and infrastructures has promoted continuing investment in the research and development of high-performance materials.

There has been significant technological progress to this end… progress which would be more substantial if integrated with new building techniques now.

It is time to bring about an evolution toward this end.

Traditional building methods – those used up to now – can be significantly transformed.
