As we kick off 2026, I’ve been reflecting on a rare privilege in my career: the opportunity to manage both large-scale civil engineering construction and mission-critical software development.
Most professionals spend their lives in one element. I like to think of them as the Fish and the Hare.
🌊 The Fish (Construction) lives in the “Deep Sea.” It’s a high-pressure world governed by the Waterfall. The laws of physics are absolute, and a single crack in the hull is fatal. 🏃 The Hare (Software) sprints across the “Open Land.” It’s a fast-paced world of Agile, where the ability to pivot is the only way to survive.
I have occupied the space between: The Turtle. I have walked the land and swum the sea, and from this vantage point, the view is fascinating.
1. The Sea: The Rigor of “Finality”
In Construction, we live by a strict hierarchy of “Finality.”
- The Gates: We move from Approval in Principle (AIP) to Pre-Final Design with a level of scrutiny that software rarely sees.
- The Checker: Before a shovel hits the ground, an Accredited Checker (AC) must independently re-calculate the Professional Engineer’s (PE) work.
- The Law: Once we get BCA ST Plan Approval, the design is “frozen.” In the sea, “Delete” isn’t a keyboard shortcut; it’s a costly demolition.
2. The Land: The Agility of Evolution
In Software, the air is different. We don’t wait for a “Final Design” to be frozen for years before we begin.
- The Sprint: We build, we test, we iterate. Our “Blueprints” (Functional Design Documents) are living organisms.
- The Pivot: If we find a better path during development, we refactor. The cost of change is measured in man-hours, not cubic meters of wasted concrete.
- Progress: It’s measured by Acceptance Criteria (AC)—is the value delivered to the user?
3. The Turtle’s Discovery: We Are Not So Different
Whether you are underwater or on land, the fundamental challenges are identical:
- The “Clash”: An MEP pipe hitting a structural beam is the physical version of two APIs failing a handshake. Both are failures of Interface Control.
- Trust but Verify: The Accredited Checker and the Independent Security Auditor are the same person—the “Third Eye” protecting the project from “single-point-of-failure” logic.
4. The Convergence: Can a Fish Run Like a Hare?
We are seeing a beautiful merger. Construction is becoming “software-like” through BIM (Building Information Modeling)—essentially “Unit Testing” a skyscraper before it’s built. Meanwhile, software is adopting the structural safety rigor traditionally reserved for civil engineering.
💡 The Turtle’s Resolution for 2026
The most successful projects of the future won’t be purely Waterfall or purely Agile. They will be Bilingual.
We need managers who respect the safety rigor of the Sea but embrace the flexibility of the Land. We must learn to measure twice (like the Fish) but move fast (like the Hare).
To my fellow “Turtles” out there—how are you bridging the gap between rigid structures and fluid logic this year?
