1) Phase 1 of the Nairobi Metro Fiber project involved laying 552 km of fiber, equivalent to the distance from Nairobi to Kampala. 2) The project took 8 months to complete and ramped up over the first 9 weeks as resources were mobilized and training was performed. 3) By 24 weeks, 500 km of trenching, duct laying, and backfilling had been completed and 300 km of fiber had been blown.

• 540 Km of 1.2m deep trench dug by sheer muscle power
• Total earth moved: 254.400m3
• If put in 20ft containers it required 7718 containers
• Enough to fill 02 Panamax-Class Container ships
• At peak Huawei had 1.000 to 1.100 labourers.
• Ericsson had at peak 500 labourers.
Most costs is local labor

• The project drew all resources available in the country.
• Machinery
• Compressors
• Jackhammers
• Trenchless Machinery
• Fusion Splicers
• To be able to complete on time need to fly in technicians and
machines from South Africa
• Ericsson knocked machines down. Airfreighted and re-assembled
them in country.
• Huawei local subcontractors imported trenchless machinery from
Germany and China to cope

7. 02nd September2013
• Kenya’s top capabilities:
• Huawei 400Km per year
• Ericsson 240Km per year
