Project description

Project name: Supporting live hood activities through agriculture in Meheba location integration area phase 2
Project Implementation: Association for Aid and Relief Japan (AAR Japan)
Project location: Meheba refugee camp in Zambia
Project beneficiaries: 54 refugees and local integrated peoples
Project duration: from 5th April to 21st June (Training by Obed was up to 6th may. Construction continued
without Obed Physically by 21st June, with daily online follow-up, led by Zambian Field assistant Gedeon).

5. Project objectives: Transferring labor-based skills of Do-nou technology to the refugees and local integrated
peoples by rehabilitating the access road from main camp to the refugee’s infrastructure and agriculture zone ofDambo-1, Dambo-2 and Kamiba
6. Reported by Eng. Ntakirutimana ObedII.

Project summary outputs❖ 54 participants have got the skills theoretically and practically and worked on three sections accordingly to thework process.
❖ 600m length of the road has cleaned❖ Total length road repaired is 276m subdivided into 3 sections which are:a) Dambo -1✓ Section of 78m has repaired and raised up to 80cm
✓ Double reinforced box culvert has constructed (3000mmx3600mmx1400mm)b) Dambo-2✓ Section of 170m has repaired and raised up to 1m✓ Two single separate reinforced box culverts have constructed (1900mmx3600mmx1400mm)c) Kamiba zone
✓ Section of 28m has repaired and raised up to 30cm
✓ One single open profile reinforced box culvert has provided (2600mmx5000mmx1200mm)

Project management

This project was managed by AAR Japan through its branch in Zambia and Invite CORE’s Engineer from Rwanda for fieldengineering aspect implementation theoretically and practically. After analyzing the site conditions and agreed on theproper interventions the previous plan of project was totally changed in increase by time and cost.

Project Execution Challenges✓ The submitted technical proposals were challenged by the site conditions and AAR’s request.
✓ The planification and Implementation on technical and field managements done at the same time. (Planning andExecution at once).
✓ Some tools and materials are not available in the location and the suppliers are from far it takes 3days to deliver
the requested materials such as bags, sands, stones, iron bars, plywood cements etc.
✓ The procurement procedure of construction materials is not easy at remote area, and required more time.
✓ More assistance to procurement entity by the Engineer was required in the procurement process.
✓ The project implementation starting period was in the raining, it has rained up to 22nd April This affect all thefield works progress and productivity.
✓ The Selected participants are refugees and vulnerable Zambian local integrated people they are not familiar ofworking a full day they are tired early and easier.
✓ Working daily hours was maximum 6hrs because of difficulties of transport to the participants it affects the daily
productivity.
✓ Supervising three sections at once as one engineer it is very challenged and tiring.
✓ Daily Online supervision is not accurate some misunderstanding can be happened in the Execution and not given
at time due to other responsibilities.

The two sections of the one road namely Dambo1 and Dambo2 are two separate sections of the road in wetland area ofzone E in Meheba refugee camp with poor condition of flooding road by overland flow, the infiltration of water into thesoil and not well maintained by ending result of a road is assumed to be completely closed when its crown is covered bywater regardless of depth, The upper side of two sections are rice farms with a lot of water without irrigation to theagriculture zone and no bridges and water pass over the road profile to reach to the next down rice farms.
The proposed intervention was to raise up road profile and provide one single box culvert with one cross drain at eachsection of Dambo1 and Dambo 2 but by physical checking on field by receiving the past information from local peoples
and observing the rain fall before 3days of starting project, the Proposed Intervention was changed by not using crossdrain rather than construction of double box culvert and raise up the road about 1m height at Dambo 1 and two
separately single box culvert and raise up the road on 80cm height at Dambo2.

Kamiba Before
Kamiba After
Kamiba After
Kamiba zone is the section of the access road from main road to training center and primary school of Kamiba village, inmiddle of the road there is big pothole as result of water stagnation from rice farms in heavy rain without drainages onboth side of the road and Road become impassable seasonally without maintenance.
The proposed intervention was to provide timber bridge at lowest point of the road similar as pothole to facilitate waterfrom up side of the road to down side of the road after explaining all technical aspect on that timber bridge, the project
implementer AAR Japan questioned about durability of timber because it is not possible to find good quality of timbers,
they requested engineer to change the top slab materials by reinforced concrete cement rather than timber materials.

Conclusion

The proper intervention of water canalization with bridges, road base reinforcement with Do-nou technology and roadprofile raising have provided to the three selected sections with maintenance roads will be passable in all seasons.

Recommendation

AAR Japan with other stakeholders should provide the irrigation Technics to the rice farms for better management ofwater in the raining seasons and the remaining bad sections in the area can be repaired using the same technics.

Lessons learnt✓ It is very important to do preliminaries studies with deep analysis by the experienced technicians during criticaltime (raining period) before planning and all technical plan (Interventions and length) be focused on thosestudies.
✓ The plan in duration and performance should be led by consideration of participants’ background, their culture
and their locations.
✓ The project management entity should be aware on construction materials specification or hire someone withknowledge for procurement purpose if not possible the invited engineer should be in the project location atleast two weeks before field project works.
✓ Number of engineers and assistants should go with number of sites and time expectation (one site project with
one experienced engineer and assistant if not at least two sites with two experienced field assistant and one
engineer as supervisor of the works).
