It is intended to assist designers in developing project specifications that communicate R12 s requirements for the construction of Network, IP Cameras, and Phone systems at their facilities. The NCGS was developed from R12 s previous version of its telecommunications infrastructure standard specifications in use at that time. It has been updated to reflect the changes that have occurred since the previous version was published. This document will supersede any other document in the event of a conflict including construction documents and specs. 1.1 DOCUMENT INTENT R12 has developed the NCGS with the intent that its standards and practices are followed during the design and construction of Network, IP Camera, and Phone infrastructure. Each NCGS specification section has references, products, procedures, processes, and work descriptions/summaries that are common to all R12 cabling projects. This information is provided in specification format to serve as a guide to the Engineer/Designer in producing a BICSI-compliant specification that will meet the unique requirements of R12 cabling projects. The NCGS is intended to be a Master Specification. The products listed and other information included in each section is intended to be all-inclusive for any given project. 2
Unless otherwise stated, the information in the NCGS applies to both new construction and remodel projects. 1.2 SPECIFICATION SECTIONS The NCGS contains the following 5 specification sections: 1 General Construction of MDF/IDF Rooms 2 Plant Cabling 3 Grounding and Bonding for Networks 4 Testing 5 Part Specifications SECTION 1 GENERAL CONSTRUCTION OF MDF/IDF ROOMS 1.0.1 REQUIREMENTS SPS Networking Dept will layout all MDF/IDF rooms for Data/Phone equipment and provide detailed drawings to Contractors.
