WAZIPOINT SYSTEM awarded Optical Fiber Cable Installation Project by DESCO

 

Fiber Cable Installation Project

Project announcement — WAZIPOINT SYSTEM awarded Optical Fiber Cable Installation by Dhaka Electric Supply Company PLC (DESCO).

Project title: Optical Fiber Cable Installation for DESCO.
Client: Dhaka Electric Supply Company (DESCO).
Contractor: WAZIPOINT SYSTEM

Scope (summary): Duct pipe laying; optical fiber cable blowing; handhole construction (1200 × 1100 × 1075 mm) with materials; supply, transport, and laying of 100 mm PVC pipe for road crossings; transportation of materials from DESCO store to site.

Start: To be confirmed with DESCO.
Status: Contract awarded.

Key highlights

• Turnkey civil and fiber works covering duct installation, cable blowing, and handhole construction.
• Road-crossing solution using 100 mm PVC conduits to protect fiber and meet traffic safety requirements.
• Logistics included — materials transported from the DESCO store to the site under the contractor's responsibility.
• As-built deliverables and test reports to be handed over on completion.

Technical execution plan (concise)

1. Assumptions and scope boundary

• Work limited to items listed by DESCO: duct laying, cable blowing, handholes (specified size), 100 mm PVC road crossings, and transportation from the DESCO store.
• Permits, traffic management approvals, and utility clearances to be obtained before civil works start.
• Final schedule and site handover dates to be coordinated with DESCO.

2. Sequence of major activities

1. Mobilization & site survey — verify alignment, locate existing utilities, mark handhole and crossing locations.
2. Traffic & safety setup — temporary traffic management, signage, and barricades for road crossings.
3. Duct pipe laying — trenching, bedding, laying ducts, warning tape, backfill, compaction.
4. Handhole construction — excavate, formwork, reinforcement, cast concrete chamber to specified dimensions, install cover and frame.
5. 100 mm PVC road crossing — install sleeve/conduit with proper encasement and warning markers.
6. Cable blowing — pre-clean and test ducts, blow optical fiber using a blowing machine, monitor tension and speed.
7. Termination & testing — splice, test OTDR, and end-to-end loss, document results.
8. As-built & handover — drawings, test reports, material certificates, completion certificate.

3. Method statements (short)

• Duct laying: Trench depth per local standard; sand bedding; ducts laid with minimum bending radius; joints sealed; warning tape 300 mm above ducts.
• Handholes: Concrete grade and reinforcement per structural requirement; internal benching and cable entry sleeves; corrosion protection for metallic parts.
• Cable blowing: Use a calibrated blowing machine; lubricants compatible with cable sheath; maintain blowing pressure logs; avoid pulling where possible.
• Road crossing: Use 100 mm PVC sleeve; concrete encasement where required; install end seals and marker posts.

4. Quality, testing, and acceptance

• Inspections: Pre-backfill inspection for ducts and handholes.
• Tests: Continuity and insulation checks for ducts (where applicable); OTDR traces and insertion loss for each fiber; power meter and light source verification.
• Acceptance: Tests must meet DESCO-specified thresholds; provide OTDR plots and splice logs.

5. Health, safety, and environment (HSE)

• Appoint an HSE officer on site.
• Provide PPE for all personnel; daily toolbox talks.
• Traffic marshals for road works; night works only with permits and lighting.
• Waste management plan for excavated material and concrete washout.

6. Mobilization checklist (minimum)

• Project team and contact list.
• Equipment: excavators, compaction tools, duct-laying rollers, cable blowing machine, OTDR, fusion splicer.
• Materials: ducts, 100 mm PVC pipes, handhole materials, warning tape, sand/gravel for bedding.
• Permits, traffic management plan, utility clearance.
• Transport vehicles for material movement from the DESCO store.
