Specifications shall, to the extent practicable, emphasize functional or performance criteria while limiting design or other detailed physical descriptions to those necessary to meet the needs of the State. To facilitate the use of such criteria, using agencies shall endeavor to include as a part of their purchase requisitions the principal functional or performance needs to be met. It is recognized, however, that the preference for use of functional or performance specifications is primarily applicable to the procurement of supplies and services. Such preference is often not practicable in construction, apart from the procurement of supply-type items for a construction project.
