Village Power Communication Line Re-Routing

Performance Work Statement: Village Power Communication Line Re‑Routing

1.0 Purpose and Background

The Village’s existing power and communication distribution network is currently routed above ground on a concrete pad using exposed cable trays. This configuration increases vulnerability to weather, physical damage, and operational disruptions. The purpose of this project is to relocate and reorganize the electrical and communication infrastructure into an underground conduit system to improve reliability, safety, and long‑term maintainability while enabling future expansion.

2.0 Scope of Work

The Contractor shall provide all labor, materials, equipment, and supervision required to install four, Ø110 mm underground PVC conduits for the Village’s power and communication lines, rerouting them from the existing concrete pad cable tray system into a new underground conduit network. Work includes:

• Excavate a trench 14 meters in length with a finished depth of 80–90 cm and a minimum finished width of 45 cm, in full compliance with IEC 60364‑5‑52 and applicable Romanian underground cable installation standards.
• Installing four, appropriately sized, Ø110 mm underground PVC conduits, for the Village’s power and communication lines conduits for electrical and communication lines.
• Ensuring all conduits are left empty, capped at both ends, and not filled, sealed, or obstructed with foam or any other material.
• All work must comply with NEC, IEEE, local utility standards, and site‑specific requirements.
• Carry out compaction testing, depth verification, and documentation to demonstrate compliance.
• Provide daily update emails on the progress of work detailing what had been accomplished that day

3.0 Requirements

1. 1. Excavation of Future Underground Conduit Locations

The contractor shall excavate a trench 14 meters in length with a finished depth of 90 cm and a minimum finished width of 75 cm, in full compliance with IEC 60364‑5‑52 and applicable Romanian underground cable installation standards.

3.1.1 Removal and disposal of previous conduit lines.

The contractor shall remove leftover conduit lines and dispose of any plastics or PVC from previous works.

3.2 Installation of Conduit lines

The contractor shall:

• Provide a 10 cm 0/4mm clean masonry sand bedding layer at the bottom of the trench prior to conduit installation.
• Use underground‑rated conduits, materials, and accessories suitable for permanent subsurface installation.
• Install four (4) Ø110 mm PVC conduits along the full trench length in a 1×4 configuration, maintaining a minimum spacing of 5-7.5 cm between conduits horizontally and vertically, and ensure each conduit terminates 92 cm above finished ground level with a clean 90‑degree sweep, are properly capped, and remain free of obstructions. The use of foam, sealant, or any filler inside spare conduits is strictly prohibited.
• Provide a draw-string in each conduit to facilitate future cable installation.
• Maintain all required horizontal and vertical clearances from existing utilities. The Contractor is solely responsible for utility locating, verification, and avoidance.
  1. Trench Backfilling

The contractor shall:

• After conduit placement, backfill with 21 cm of 0/4mm clean masonry sand to cover the exposed conduits. This will lead to a total sand layer of 31 cm due to the bedding layer and additional backfill.
• Install warning tape 30cm above conduit crown.
• After sand layer, the trench will be backfilled with 37mm of 0/32mm well-graded crushed aggregate.
  1. Concrete Capping

The contractor shall:

• Restore the surface with a 22 cm concrete slab matching the adjacent concrete thickness, strength, finish and appearance.
• The repaired section will be flush with surrounding surfaces with no visible differential in texture, color, or elevation.
  1. Additional Requirements

The contractor must:

• Implement all necessary site protection, erosion control, and restoration measures throughout the work.
  
  • This includes wearing protective helmets, gloves, knee pads, and respiratory masks to protect from cuts, inhaling concrete dust, and any other potential bodily injury
• Maintain daily progress logs and submit daily work reports in PDF format to the Contracting Officer and the Project Manager.
• Clean any the surriounding area of leftover materials, dust, and debris.
• Fill hole located by the designated red circle on figure 2. This should be done manually with shovels and at the end of the project to ensure there is no damage done to the concrete foundation and the structures surrounding it.
• Execute work from 9AM to 5PM.
• Not pour concrete when storms are suspected during the curing time of the concrete.

4.0 Deliverables

The Contractor shall deliver:

• Underground routing plan and construction drawings.

• Material submittals and technical data sheets.

• As‑built drawings showing conduit paths, depths, and cable identification.

5.0 Period of Performance

The period of performance is 14 working days from Notice to Proceed (NTP). A detailed schedule with milestones shall be submitted within 10 days upon award.

6.0 Place of Performance

All work will occur within the Village boundaries at the existing concrete pad cable tray locations and along the approved underground routing corridors.

7.0 USG & RoAF Assistance

The U.S. Government and Romanian Air Force may provide:

• Access to controlled areas and work zones.

• Coordination with local authorities and utility providers.

• Review and approval of submittals and design documents.

• Oversight and quality assurance inspections.

• No tools, materials, or labor will be provided by RoAF or USAF unless specifically stated.
