Why are we here? To think about …..The Riser as a Contract Document• Idea
Components of a structured cabling system can be fully described on one– Components of a structured cabling system can be fully described on one schematic riser diagram.
• What– CAD drawingCAD drawing– Different from current drawing practice and focuses on the cabling, not conduit or
pathways. – CAD Library of graphic elements described in detail.
• Examples– Illustrate how the symbols are used to define and specify a complete cabling
system.
I l d d th• Included are the – type and pair count of different cables and cable types, – termination types, – termination locations– termination locations, – cross connections and – patch-cords
What will we learn? ObjectivesWhat will we learn? Objectives– Context of a construction contract– Legal nature of a contract– Establish need for clarity and completenessy– Identify key documents for structured cabling– Identify use of LAYOUT PLANSy– Identify proper use of SPECIFICATIONS– Identify use of SCHEMATIC RISERIdentify use of SCHEMATIC RISER– How to prepare a RICH DETAIL FORMAT
(RDF) RISER SCHEMATIC( )
O d i dContext – Owner, designer and contractor operate together in a world of contract lawin a world of contract law
Owner + $$ + idea +– Owner + $$ + idea + designer = Contract DocumentsContract Documents
Contract Documents+– Contract Documents+ Contractor + materials = work results
P d P U f C t t D tPurpose and Proper Use of Contract Documents
• General terms and conditions– Establishes relationship between the
Contractor and the Owner– Details the do’s and don’ts of the work– Sets up contract as p Construction Management (CM) or General Contract (GC)
– CM or GC can affect way Data cabling is sub-contracted
• SpecificationsPurpose and Proper Use of Contract Documents
p– Legally reinforces what is on the drawings– Defines scope of workp– Defines material components
• Designer will use specifications toE d f k– Expand on scope of work
– Detail desired components– Describes special execution of work
P d P U f C t t D t
• Specification split by description of Work
Purpose and Proper Use of Contract Documents

Division 27 - Communications• General description of workp
– What is included and excluded– Look for “Provide” or “Install” or “Furnish”.
• Definitions of Cable type and performance– Cable type and performance
– Connector type and performanceStandards for execution/installation– Standards for execution/installation
– Testing and test reporting
Correct use of drawings- layouts• Communications layout drawingsy g
– Outside plant shows conduits and site routing
– Inside plant Outlets – positions and jack count Telecommunications rooms Conduit and tray (sometimes)
• Contractor responsible for– Take off - quantity
Correct use of drawings- elevations
• Communications elevation drawingsg– Communications rooms Identifies racking Identifies wall layouts Identifies cable routing
Correct use of drawings- riser• Communications Riser drawingsg
