How big should the MDF be?+
Minimum 100 sq ft for a small commercial building; 200-400 sq ft for a multi-floor building with multiple carrier drops, phone system, and backup power. TIA-569-D recommends 12 sq ft per floor served. Larger is always better than smaller.
How much does an MDF buildout cost?+
New MDF from scratch: $30-100k depending on rack count, cabling scope, and power. Buildout of an existing shell room: $20-60k. Numbers exclude major electrical, cooling, and fire suppression which are quoted separately.
Can you buildout an MDF during TI construction?+
Yes — this is the ideal time. Coordinate with the GC on framing, electrical rough-in, cooling ductwork, and finishes. We install racks, backbone cabling, and terminations before the building goes live.
Do you handle the ISP demarc extension?+
Yes — from the utility drop or building demarc to the MDF, following carrier requirements. AT&T, Lumen, Comcast Business, Spectrum, Wave, Sonic, and every major California ISP.
How is the MDF different from an IDF?+
MDF is the central room for the building — carrier demarc, core routing, phone system head-end, and backbone termination for every IDF. IDFs are the intermediate rooms on each floor or wing that home-run the horizontal cabling and connect back to the MDF over the backbone.
What about grounding and bonding?+
Full TIA-607-D compliant grounding: primary bonding bus, telecom bonding backbone to every IDF, and every rack bonded. Documented in the closeout with photos and grounding diagrams.
