Pre-Construction Data Checklist

The 5 critical data points you must verify before investing a single dollar in earthworks

⚠️ Warning: 83% of irrigation schemes across Africa are underperforming or have completely failed. Most of these failures could have been prevented with proper data collection at the feasibility stage. Use this checklist to identify gaps in your current knowledge and ensure your project is built on certainty, not assumptions.

1. Site & Topography Data Essential

You cannot design what you do not understand. Accurate site data is the foundation of every successful irrigation project.

Precision Topographic Maps (1:500 scale)
Do you have detailed contour maps showing elevation changes, slopes, and drainage patterns across your entire farm?
Not Started
Digital Terrain Model (DTM) Data
Do you have a digital 3D model of your terrain that can be used for hydraulic modelling and design?
Not Started
Property Boundary Survey
Are your property boundaries clearly defined and surveyed to avoid legal disputes during construction?
Not Started
2. Water Resources Data Critical

Water is the lifeblood of your farm. Without accurate data about availability and quality, your entire investment is at risk.

Verified Borehole Yield Certificate
Do you have a proven, sustainable yield certificate—not a driller's log? The difference can be 40% or more.
Not Started
SAR Water Testing (Sodium Absorption Ratio)
Has your water been tested for sodium content? High SAR water destroys soil structure and reduces infiltration.
Not Started
Full Water Quality Analysis
Do you know the pH, electrical conductivity, and mineral content of your water source?
Not Started
Water Rights & Legal Compliance
Do you have legal water rights, permits, and documentation confirming your entitlement to abstract water?
Not Started
3. Soil & Land Data Critical

Your soil determines how water is absorbed, stored, and delivered to crops. Soil is not uniform—and you cannot guess what's underground.

Laboratory Soil Infiltration Profiles
Do you know exactly how fast water will infiltrate into your soil? Different soil types absorb water at dramatically different rates.
Not Started
Comprehensive Soil Mapping (Across the Entire Farm)
Do you have soil data from multiple sample points across your farm? Soil varies significantly—sometimes within the same field.
Not Started
Soil Salinity & Fertility Analysis
Do you know your soil's salinity levels, nutrient content, and pH? Saline soils require different irrigation management.
Not Started
4. Stakeholder & Governance Data Essential

The most expensive mistake in farm infrastructure is building something that communities will not support. Consultation is not optional—it's essential.

Stakeholder Mapping & Analysis
Have you identified all relevant stakeholders—government, funders, communities, contractors—and understood their interests?
Not Started
Community Engagement Strategy & Records
Do you have documented evidence that communities and traditional authorities were consulted and have given their support?
Not Started
Governance & Management Framework
Do you have a clear governance structure that defines who manages the scheme, who maintains it, and how disputes are resolved?
Not Started
Environmental & Social Compliance Documentation
Do you have Environmental Impact Assessment (EIA) approvals and social compliance documentation in place?
Not Started
5. Financial & Viability Data Essential

Good intentions are not enough. Your project must make financial sense. Banks and funders require auditable data—not assumptions.

Financial & Economic Viability Model
Do you have a financial model showing projected returns, payback period, and net present value (NPV) of your investment?
Not Started
Definitive Cost Estimates with Contingency Reserves
Do you have detailed cost estimates that include a realistic contingency fund for unforeseen challenges?
Not Started
Project Charter (Defining Scope, Objectives, and Success Metrics)
Do you have a single document that defines exactly what you're building, why, for whom, and what success looks like?
Not Started

📋 Your Next Steps

If you're missing 3 or more critical data points: Your project is at significant risk. Schedule a feasibility consultation to get the data you need before investing further.

If you have 12 or more items verified: You're on the right track. Contact us for a complementary review of your documentation.
