“Terrazzo in the hands of an NTMA contractor is truly the art of craft.”


The National Terrazzo and Mosaic Association annually conducts the awards program to honor member contractors for executing exceptional terrazzo work. Projects are judged on the basis of excellence in design and implementation, quality, and craftsmanship. The judging process is completely non-biased and conducted by a panel of terrazzo experts who are not made aware of the contractor or location of each job they are evaluating.

The judging for the Honor Awards consists of five terrazzo experts in the fields of architecture, design, and contracting. Their decision is based upon:

▪ Excellence in craftsmanship
▪ Excellence in design
▪ Scope of installation

The terrazzo industry’s highest recognition, is the Job of the Year, the best project among the 13 – 15 Honor Award Winners.
The winning project and the Honor Awards are selected from among various internationwide terrazzo projects submitted by NTMA members.
The NTMA requirements must be met for the job to be considered for the competition.

For all terrazzo specifications, VIA.ZZO refers to the National Terrazzo & Mosaic Association (NTMA), the central source for terrazzo technical data, details, and specifications. For more in-depth information on terrazzo systems, visit the specifications section of NTMA website.
