Inside Plant and Outside Plant Construction

Inside plant, outside plant, and the excavation that connects them. We build the physical network for military installations, campuses and federal facilities, from the duct bank to the patch panel, under Marty Dinnan’s direct project management.

  • 25+ Years Experience
  • 15+ Military Installations
  • $10M–$15M Largest Single Contract

Outside plant construction: the backbone between buildings

Conduit, manholes, handholes, aerial strand and the fiber or copper cable that ties a campus or installation together. On federal sites, outside plant construction also means base Civil Engineering coordination, dig permits, utility locates and strict restoration requirements.

  • Underground conduit Trenching, directional boring, duct banks, manholes and handholes.
  • Aerial construction Pole lines, strand, lashing and aerial cable placement.
  • Fiber splicing Fusion splicing, OTDR testing and splice enclosures.
  • Site restoration Seeding, paving and concrete to base standard.

Built to UFC 3-580-01, with as-built documentation for the installation’s records and environmental and historical preservation compliance.

Inside plant construction: from the entrance facility to the work area

Main and intermediate distribution frames, equipment rooms, telecom closets and the structured cabling that connects them. On military installations, inside plant work demands precision and strict adherence to BICSI, TIA and installation-specific standards.

  • MDF and IDF build-outs Racks, cable management, grounding, power and labeling.
  • Structured cabling Cat 6 and 6A, fiber backbone and copper horizontal runs, terminated and tested.
  • Testing and documentation Results for every run, packaged for federal inspection.
  • Controlled-access facilities Work inside secure buildings under installation handling procedures.

Standards we build to: BICSI TDMM, TIA-568, TIA-569, TIA-606 and TIA-607, NFPA 70 and UFC 3-580-01, plus each installation’s design guide and statement of work.

The trench is part of the network

M.A.D.E runs its own excavation crews and equipment, so site work and cable work stay on one schedule, including multi-site programs running on several fronts at once.

  • Trenching and shoring Utility excavation with trench protection in place.
  • Vaults and handholes Handhole, vault and manhole setting.
  • Clearing and grading Clearing, grading and GPS surveying.
  • Restoration and mobilization Asphalt and concrete restoration; crews and equipment moved to remote installations.
