Bill of Materials (BOM) — Per single telecom hand hole

Per single telecom hand hole: Below is a practical, specification-ready BOM. Quantities assume a single handhole installation (adjust multiplication for a project). Notes give guidance on selection/spec.

  1. Handhole body + lid (material: choose PC / HDPE / FRP) — Qty: 1 set
    • Specify Tier/load rating, internal dimensions, and lid fastening type (security penta/hex). (PC for roadway; HDPE for light duty; FRP for moderate/corrosive).
  2. Lid lifting tool / key — Qty: 1
    • Vendor-specific key (hex/penta), for safe access.
  3. Prefabricated duct entries / grommets / seals — Qty: as needed per entry (typically 2–6)
    • Rubber grommets or molded sleeves to protect cable and seal against water/rodents.
  4. Innerduct (corrugated/HDPE) — e.g., 1.25″ or 2″ — Qty: depends on number of spares (typical 1–4 runs)
    • Use color-coded innerduct for blow/pull installations.
  5. Fiber cable (drop or distribution) — as specified — Qty: per design (meters/ft)
  6. Splice trays / splice holders (rack style) — Qty: 1–4 depending on fiber count
    • Sized for fusion splices; stackable trays recommended. (See handhole sizing guidance for storage).
  7. Cable ties, Velcro, mounting hardware — Qty: assorted
    • For securing innerducts, slack loops and splice trays.
  8. Slack storage bracket / fiber storage reel (or bend-radius control panel) — Qty: 1 set
    • To maintain minimum bend radius and store excess fiber.
  9. Grounding rod & clamp (if required by spec) — Qty: 1
    • Grounding often required for metallic components or when specified by utility codes. (Polymer concrete/FRP may be nonconductive, but any metallic lid or adjacent telecom grounding needs attention).
  10. Concrete base pad or leveling sand / bedding stone — Qty: per handhole (e.g., 12″ thick compacted base or concrete slab as specified)
    • Many installation guides require compacted bedding or a concrete slab under the handhole for stability.
  11. Backfill material (select granular fill) & compaction equipment — Qty: per excavation
    • Granular backfill to avoid voids and protect the handhole.
  12. Mastic / sealant for duct entries and lid gasket — Qty: tubes/cans as required
    • Use manufacturer-recommended compounds to seal around duct entries.
  13. Warning tape (underground cable warning tape) — Qty: per run (100 ft typical rolls)
  14. Bolts / security fasteners / neoprene washers — Qty: per lid (typical 4–8 fasteners)
  15. Pulling eye / dead-end hardware (if required) — Qty: per design
  16. Traffic safety gear / temporary covers / cones — Qty: as required for safe work
  17. Labels / asset tags / QR code plates — Qty: 1 plate per handhole
    • For inventory and maintenance.
  18. Optional: polymer concrete patch / concrete grout (for leveling) — Qty: small bag
  19. Tools & consumables: fusion splicer (if splicing), heat shrink sleeves, cleaning supplies, lubricants for blowing/pulling, cable reel stands, conduit cutters, saws, compactor rental.

Quick installation / specification notes (best practice)

  • Sizing for slack & splicing: follow handhole sizing guides (store required spool length, maintain minimum fiber bend radius). Larger fiber counts require larger handholes or vaults.
  • Concrete bedding: compacted bedding or a concrete slab provides stable support and reduces point loading on the handhole base in freeze/thaw areas.
  • Duct sealing & rodent protection: use rubber grommets and sealants at each entry and install rodent guards where required.
  • Choose lids with security fasteners in public areas to prevent tampering; specify lifting tools in the BOM.
