Activity Index · as of July 20267 counties · the territory this index covers
Every public Site Work, Paving & Drainage project in California pulls in a stack of firms — a general contractor to run it, specialty trade and engineering firms to execute the technical work, and architects or consulting engineers to design it. The Activity Index maps who shows up most across each of those layers.
Within a layer, the most active firm is set to 100 and everyone else is indexed to it, so you can read competitive position at a glance — without anyone claiming to know a firm's literal market share. The true share of tracked activity sits beside every ranking, so the math stays visible.

Why the pipeline is deep right now
Public Site Work, Paving & Drainage work in California moves on its own capital cycle — bond votes, agency budgets, and multi-year facility plans — which keeps the pipeline broad enough for multiple firms to stay active in most layers at once.
How to use this
See a market this clearly, and you can play it two ways.
The layer you compete in tells you who you're actually up against — and the firms above you are the ones winning the work you want. The relative view is the point: it shows where a layer is locked up by one or two names, and where it's wide open and share is there to take.
The parties you're not competing with — the architect, the construction manager, the owner's rep — are your way onto a project. Signal Relationship Intelligence maps the shortest path from someone you already know to the people deciding the work.
Pair either angle with the projects themselves — owner, stage, and timing — and outreach stops being a guess. That project-level detail, and the paths through your network, are what SymplSignal puts behind every firm on this page.
