MORE THAN WHAT GETS BUILT

The Work Behind the Work.

Every successful project has another story behind it.


The early conversations. The feasibility questions. The budget decisions. The design adjustments. The coordination between teams. The problems solved before they become expensive problems.

That is where Sigma comes in.

We bring together architectural understanding and construction expertise to help projects move forward with greater clarity, control, and purpose.

01 / Preconstruction

Start With the Right Decisions.

The strongest projects begin long before construction starts.

Sigma helps owners and project teams evaluate feasibility, develop budgets, review constructability, assess risks, establish schedules, and make informed decisions before work begins.

THE SIGMA APPROACH

See the Build
Before It Begins.


Good construction management starts with looking ahead.

Before construction begins, Sigma considers the details that can shape a project's outcome: cost, constructability, scheduling, site conditions, coordination, risk, and the decisions that can make the difference between a smooth project and a difficult one.

By addressing those considerations early, we help create a clearer path forward.

PROJECT EXPERIENCE

Different Projects. One Focus.


Sigma’s experience spans a range of building environments, each with its own challenges, requirements, and opportunities. From pre-engineered buildings and commercial developments to multifamily and medical projects, Sigma brings a flexible approach grounded in the specific needs of each project.

THE PERSON BEHIND SIGMA

Built From Two Perspectives.

Architect. Construction Manager. Problem Solver.


With a degree in architecture and more than 27 years of construction management experience, Gerry Svoronos brings two sides of the building process together.

He understands the vision behind a design, but also the realities of bringing that vision to life.

That perspective shapes Sigma's hands-on approach to leadership, collaboration, cost, quality, and execution.
