How we work

Clarity through every project phase.

Sigma replaces fragmented handovers with one connected process—from the first project question to coordinated delivery.

Sigma / 2026

01 / The model

One project structure

The right decisions, in the right order.

Each phase produces the information the next phase needs. That keeps design, engineering, approvals and site work aligned around the same brief.

01

Brief & survey

We establish the project question, site constraints, existing conditions and the decisions required before design begins.

02

Design & coordination

Concept, preliminary and detailed design are developed with engineering input so the proposal remains buildable.

03

Documentation & approvals

Authorizations, execution plans and tender documents translate the design into a coordinated delivery package.

04

Delivery & site

Site supervision and interior delivery close the loop between drawing, construction and the finished place.
