Practical project controls for construction teams

Sum Span creates straightforward digital tools for construction teams that want better visibility without adding another complicated software platform.

Project control lives at the intersection of money and time. Sum Span is built around making the costs, commitments, exposure, schedule impacts, and decisions behind a project easier to see and manage.

The focus is practical project control: organizing changes, costs, revenue, aging, schedule impact, and other information that project teams need to manage every day.

Our templates are designed to be understandable, editable, and useful in a real project workflow. That means familiar file formats, transparent formulas, no macros where they are not needed, and no recurring software subscription just to keep using a spreadsheet you already purchased.

The first product, the Construction Change Order Exposure & Margin Tracker, goes beyond a basic change log by separating owner-side revenue from vendor and project costs so teams can see pending exposure, unrecovered committed cost, aging, and realized margin in one place.

These tools are project-management aids. They do not replace your contracts, company procedures, accounting systems, or professional advice.
