Decagon Engineering

Infrastructure that moves people, reliably

Planning, design, and supervision of roads and transportation infrastructure, built to standard and engineered to last beyond the first rainy season.

What We Deliver

Roads engineered, not just paved

Poorly designed drainage and pavement are the leading cause of early road failure. Our transportation engineering practice designs for the ground and the climate a road will actually face, then supervises construction to make sure that design gets built.

Designed for the corridor it serves

Roads rarely fail in isolation, drainage, utilities, and surrounding infrastructure all shape the design. We plan for the corridor as a system, not just the pavement.

How It Works

Design that survives the ground

Step 01

Traffic & Site Study

We assess traffic volumes, terrain, and existing infrastructure to establish the design requirements for the corridor.

Step 02

Pavement & Drainage Design

Pavement structure and drainage are designed together, the single biggest factor in whether a road lasts its intended lifespan.

Step 03

Construction Supervision

We supervise construction against the design and specification, catching deviations before they're buried under the next layer.

Step 04

Rehabilitation & Upgrades

For existing infrastructure, we assess condition and design cost-effective rehabilitation rather than defaulting to full reconstruction.

Planning

The design is only as good as the site data

Traffic counts, terrain, and existing utilities are surveyed on site before a single line is drawn, so the design responds to the corridor as it actually is.
