B. Division 27 is based on NFPA 70 (NEC), National Electrical Safety Code (NESC), Institute of Electronic and Electrical Engineers IEEE, ANSI/TIA/EIA Telecommunication Standards, and BICSI methodologies. The requirements within those documents are not superseded herein unless specifically stated. As required, NEC and NESC code requirements cannot be superseded by this document at any time. ANSI/TIA/EIA standards and BICSI methodologies may be superseded, as specified, or may be made stricter by this document. The absence of a specific reference to an element of these codes, standards, and methodologies does not relieve all parties of compliance with them.

C. Within this document use of the word “shall” marks mandatory requirements. Use of the word “may” or “should” suggests optional elements. All conflicts within this document shall be resolved by Coastal Carolina Univ. in consultation with the CCU Information Technology Services (ITS) Department prior to application of the specification by a Contractor.

D. CCU ITS must approve any deviation from the specifications and guidelines in this document. All communications, correspondence, and approvals must come be conveyed through the official project contacts of record such as the Architect and Construction Manager.

E. Unauthorized deviations from these Specifications may result in re-design, reconstruction, or re-installation of physical communications elements at the contractor’s expense. Contractors shall obtain formal written approval prior to bidding and prior to installation in order to deviate from these Specifications or from ANSI/TIA/EIA standards and BICSI methodologies.
