Design Guidelines

Revised October 2015

Instructions:

These design guidelines describe in detail the type and quality of systems and materials expected in Knox

County School facilities. They are to be used as a guide only. It is up to the design team and construction team to propose innovative solutions that provide for greater efficiency and effectiveness as well as provide a cost savings. Building maintenance and life-cycle costing are important considerations throughout the design process. All alternates proposed to these design guidelines must be described in detail. The reasons for the proposed alternates must be given as well. Knox County expects a revised version of this document to be provided by the successful design-build team upon completion of the school project(s).

All references to brand names, trade names, model numbers or other descriptions peculiar to specific brand products are made to establish a required level of quality and functional capabilities, and are not intended to exclude other products of that level. Comparable products of other manufacturers will be considered if proof of comparability is provided. It shall be the responsibility of the design team and construction team to furnish with such specifications, submittals, brochures or other data that will provide an adequate basis for determining the quality and functional capabilities of the product offered. Knox County encourages all design teams and construction teams to propose innovative solutions that equal or exceed the quality listed in these design guidelines and provide a cost savings.
