Infrastructure Development Requirements Document
This is a practical guide to building a requirements document for an infrastructure development project — the documented needs the solution must meet, adapted to the realities of delivering large public or private infrastructure.
What a Requirements Document is
A requirements document is the documented needs the solution must meet. For the full concept and how it works in general, see Requirements Document. On an infrastructure development project it plays the same role, tuned to this kind of work.
Why it matters for an Infrastructure Development project
Infrastructure Development projects live or die on delivering large public or private infrastructure. A well-built requirements document gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how infrastructure development projects drift into avoidable delay and cost.
What to include
- Business requirements
- Functional requirements
- Non-functional requirements
- Acceptance criteria
- Traceability
Infrastructure Development-specific considerations
Tailor the requirements document to the risks that most often derail infrastructure development projects:
- Long lead times
- Permits and land
- Cost inflation over long horizons
Example
On a real infrastructure development project, the requirements document would be shaped by delivering large public or private infrastructure. In particular, it should explicitly account for the project’s biggest risks — long lead times, permits and land, cost inflation over long horizons — rather than treating them as afterthoughts.
