BICSI RCDD study plan
BICSI RCDD · Give each week a clear focus.
8 weeks · About 7 hours per week
Design Basics & Cabling Infrastructure
Map the RCDD exam blueprint to your own study checklist, weighting Design Basics and Cabling Infrastructure most heavily
Define the core design-basics vocabulary (topology, redundancy, capacity, scalability, serviceability) and write a one-line definition for each
Explain how a needs assessment drives media selection and pathway sizing
List the standard copper and fiber media categories with their distance and bandwidth limits and self-quiz until you can recall each from memory
Your checkpoint
A one-page media-selection cheat sheet covering copper categories and fiber types with their rated limits
Cabling Infrastructure
Compare balanced twisted-pair, coaxial, and optical fiber media on bandwidth, distance, EMI immunity, and cost
Describe connector and termination standards for each media family and identify common field-termination errors
Calculate channel length budgets for a mixed copper/fiber backbone and document the assumptions
Explain testing requirements (insertion loss, return loss, NEXT, length) for copper and fiber links
Your checkpoint
A worked length-budget worksheet for a sample two-building campus with copper horizontal and fiber backbone
Telecommunications Spaces and Architecture & Cabling Infrastructure
Describe the roles of the entrance facility, equipment room, telecommunications room, and telecommunications enclosure
Specify environmental, power, grounding, and bonding requirements for a telecommunications space
Size a telecommunications room for a given floor area and cable volume using standard planning rules
Cross-check cabling-infrastructure media choices against the space and pathway constraints you identified
Your checkpoint
A telecommunications room specification sheet covering size, environment, power, grounding, and bonding
Telecommunications Distribution Systems & Design Basics
Distinguish horizontal, backbone, and campus distribution and the media typically used in each
Design a horizontal distribution layout for a sample floor plan with pathways, spaces, and consolidation points
Apply separation and pathway-routing rules to avoid EMI sources and fill-ratio violations
Produce an administration scheme (labels, records, identifiers) for the sample design
Your checkpoint
A sample floor-plan distribution design with pathway routing, cable counts, and labeling scheme
ICT Systems and Applications
Describe the structured-cabling dependencies of common ICT applications (data networking, voice, wireless access points, building automation)
Explain how PoE, bandwidth demand, and latency requirements influence cabling and topology choices
Identify where security, firestopping, and life-safety systems intersect with ICT infrastructure
Compare centralized versus distributed (zone) cabling approaches for a given application scenario
Your checkpoint
An application-to-infrastructure mapping table showing cabling and topology requirements for at least six ICT systems
Project Management, Documentation, and Administration & Design Basics
List the core project documents (drawings, specifications, schedules, test reports, as-builts) and who owns each
Describe a design review and commissioning workflow from concept through handover
Explain change management, RFI, and submittal processes and how they affect design integrity
Draft a scope and responsibility matrix (RACI-style) for a small cabling project
Your checkpoint
A project document checklist plus a one-page responsibility matrix for a sample cabling project
Design Basics & Cabling Infrastructure & Telecommunications Spaces and Architecture & Telecommunications Distribution Systems & ICT Systems and Applications & Project Management, Documentation, and Administration
Revisit your weakest domains based on practice-question error analysis and log each gap
Redo any deliverable that scored below your own standard and correct the errors
Practice explaining design decisions out loud as you would to a client or reviewer
Build a one-page summary sheet per domain capturing the key rules and numbers
Your checkpoint
Six single-page domain summary sheets plus a prioritized list of remaining weak areas
Design Basics & Cabling Infrastructure & Telecommunications Spaces and Architecture & Telecommunications Distribution Systems & ICT Systems and Applications & Project Management, Documentation, and Administration
Complete a timed full-length practice exam and score it by domain
Analyze every missed question to root cause (knowledge gap, misread, or calculation error)
Drill the two lowest-scoring domains until you can answer without notes
Review all summary sheets and confirm you can recall key standards-based limits from memory
Your checkpoint
A scored practice exam with a written remediation log and a final readiness assessment
Milestones
Week 2: Can state copper category and fiber type limits from memory and complete a length budget without reference
Week 4: Produce a floor-plan distribution design that passes your own checklist for pathways, separation, fill ratio, and labeling
Week 6: Explain the full project document and commissioning workflow end to end without notes
Week 8: Score at or above your target on a timed practice exam with no domain below your minimum threshold
