Advantages Of Material Specifications Over Performance Specifications.

• The material specification determines if the contractors substitute is equal to or better than the named product.
• The material specification endures the possibility of better accuracy of strength and corrosion resistance.
• By analyzing using the material specification it allows an easy access over the performance specification to alter or change while construction.

An ongoing project near Denver has been visited. A multi storied commercial building is constructed, in which the material specification is being used; the material specification was of open in type. This open specification gave a name to the proprietary and allowed substitutions. This was completely governed by the designer that the builders substitute was better than the named product.

The open type material specifications were used because it was more economical and performed better than the performance specification and closed specification.
