GNSS/RTK Surveyor – IDP Relocation Sites – Jowhar, Somalia

Terms of Reference (ToR)

GNSS/RTK Surveyor–IDP Relocation Sites (Jowhar, Somalia)

Project: Jowhar Off-Stream Storage Programme (JOSP) Implementing Partner: Shaqodoon Organization Location: Jowhar District, Middle Shabelle, Somalia

Sites: Three relocation sites (2 in Naxarow, 1 in Ali Alin), located outside Jowhar town

1. Background

Shaqodoon, in partnership with the International Organization for Migration (IOM) under the JOSP programme, is supporting the relocation of flood-affected and vulnerable communities currently residing along the Sabuni Canal, which is scheduled for rehabilitation by the Food and Agriculture Organization (FAO). As part of this process, communities will be relocated to three (3) planned sites across two different locations—two sites in Naxarow and one in Ali Alin, all situated outside Jowhar town.

The relocation sites have been designed using a Resilience Design (RD) approach, which integrates:

• Climate-resilient settlement planning
• Water and soil management systems
• Livelihood and ecological zoning
• Conflict-sensitive spatial arrangements

These designs have been carefully developed to ensure long-term sustainability, reduced disaster risk, and improved living conditions for relocated households. To ensure accurate and faithful implementation of these georeferenced designs on the ground, a high-precision GNSS/RTK surveyor is required to translate digital spatial plans into precise, on-the-ground layouts

2. Purpose of the Assignment

The primary purpose of this assignment is to support the accurate ground setting-out of RD settlement plans (Attached) using GNSS/RTK equipment with centimeter-level accuracy. The surveyor will ensure that:

• Settlement layouts are faithfully translated from design to field
• Household plots, infrastructure, and ecological systems are correctly positioned
• Errors during implementation are minimized, avoiding costly rework

3. Scope of Work

3.1 Pre-Survey Preparation	The surveyor shall: • Review all provided design files, including: CAD drawings KMZ/KML files and Coordinate datasets (EPSG:32638–UTM Zone 38N) • Confirm alignment between coordinate systems and field equipment • Identify and flag discrepancies, inconsistencies, or missing data prior to field deployment • Prepare survey equipment and data collection templates • prepare metadata list and share for confirmation • share calibration records of the equipment to be used
3.2 Site Reconnaissance	• Conduct joint site visits with shaqodoon technical team • Verify site boundaries and reference points; and existing physical features (vegetation, structures, terrain) • Identify potential constraints such as flood-prone areas, access limitations, soil or terrain challenges • Provide initial feedback before staking begins
3.3 GNSS / RTK Technical Requirements	The surveyor must: • Use RTK-enabled GNSS equipment capable of centimeter-level accuracy • Achieve minimum accuracy standards Horizontal:≤3 cm, Vertical:≤5 cm • Record full metadata for all collected points,
3.4 Setting-Out / Staking	The surveyor will stake out the full site layout, including: • Residential Components: Household plots and boundaries and plot corners and identifiers • Infrastructure: Roads and access paths; and community/public areas (schools, markets, water points where applicable) • Ecological & RD Systems: Bioswales and drainage lines; berms and contour structures; water retention features; livestock areas; and tree planting and green zones
3.5 Marking and Staking Standards	• Use durable and clearly visible stakes suitable for site conditions • Apply wood rods with writing on the right side according to the designated use (using a marker), to be agreed with the RD consultant; for example: residential plots, roads, and ecological systems. • Ensure markings remain visible throughout initial construction phase • Clearly label key points where required
3.6 Verification and Quality Assurance	• Re-check at least 20% of all staked points, randomly selected across all the different designated use • Conduct joint verification with Shaqodoon technical team and RD consultant to correct any deviations immediately • Ensure full alignment with design files before handover

 

3.7 Implementation Support

• Respond to clarification requests from field teams • Re-stake or adjust points if required due to site realities

4. Deliverables

The surveyor shall submit the following:

1. Fully staked and verified sites (all three sites) 2. CSV file of all surveyed and staked points
2. Updated CAD and GIS files reflecting actual field conditions 4. Raw GNSS/RTK logs and metadata
3. Verification report (including QA checks and corrections made) 6. As-built survey (if required)
4. Coordination and Reporting

The surveyor will work closely with:

• Shaqodoon technical team (primary coordination)
• RDC / Resilience Design technical experts/consultant
• JOSP / IOM engineering and coordination team
• Regular updates and coordination meetings will be required during fieldwork.

6. Timeline

The  assignment will be  implemented  over  an  initial  period  of three  (3) weeks, with a  clear prioritization of critical infrastructure to enable immediate site works, followed by detailed settlement  staking. A  short  follow-up  period  (as needed) may be  required  for  adjustments and re-staking.

Week	Scope
Week 1: Mobilization, Preparation, and Primary Layout Setting	Objective: Enable immediate commencement of earthworks and major site development. • Rapid review of all design files (CAD, KMZ, coordinates–EPSG:32638) • Confirmation of coordinate system alignment and identification of discrepancies • Site reconnaissance across all three locations (Naxarow x2, Cadalow x1) • Establishment of control points and GNSS/RTK base setup • Priority staking of critical infrastructure: o Main access roads and primary pathways o Key earthworks (drainage lines, bioswales, berms) o Major site boundaries and zoning areas • Initial verification of primary layout with Shaqodoon team
Weeks 2–3: Detailed Settlement Staking and	Objective: Complete full settlement demarcation at household and community level. • Detailed GNSS/RTK staking of: o Individual household plots and boundaries

 

Secondary Layout	o Secondary and tertiary pathways o Community/public spaces o Livelihood and ecological zones (livestock areas, planting zones, etc.) • Application of marking standards (durable stakes, color coding) • Ongoing coordination with implementation teams to align with construction sequencing • Continuous quality checks during staking
End of Week 3: Verification,  QA, and Handover	Objective: Ensure accuracy and readiness for full implementation. • Re-survey and verification of at least 10% of all points • Joint verification exercise with Shaqodoon and partners • Correction of any discrepancies or deviations • Submission of: o CSV of surveyed points o Updated CAD/GIS files o GNSS raw logs and metadata • Final site handover and briefing
Follow-Up–As Needed	Objective: Support implementation phase and address emerging needs. • Re-staking of disturbed or adjusted points • Technical clarification to contractors and field teams • Spot checks to maintain alignment with design
