Summary
OSTACOLO is an Autodesk Revit add-in designed to manage clash detection, tracking, and resolution directly inside the Revit environment. Instead of relying entirely on external coordination platforms and repeated export/import workflows, OSTACOLO keeps clash identification and issue management within the active project model. It stores clash data persistently in the Revit file using Extensible Storage while also maintaining a structured JSON database for sharing and offline coordination.
Core Purpose
The primary purpose of OSTACOLO is to turn clash coordination into an in-model workflow. Traditional clash detection often requires moving data between Revit and separate coordination applications, which can create extra steps, disconnected issue records, and coordination overhead. OSTACOLO addresses this by detecting clashes, placing visual markers, storing issue data, and managing clash status changes without requiring users to leave Revit.
Detection Protocols
OSTACOLO detects geometric conflicts using five configurable discipline protocols. These include Structural vs MEP, Architecture RC versus Structural and MEP, Architecture WD versus Structural and MEP, MEP Internal, and a combined All protocol. This structure allows users to target specific coordination scenarios rather than running only broad, unfocused clash tests.
The Architecture RC protocol focuses on roof, floor, and ceiling elements, while the Architecture WD protocol focuses on windows and doors. MEP Internal checks conflicts within MEP disciplines, and the All protocol provides a broader combined coordination review. Each protocol can be configured to suit the coordination goals of the project team.
Hard Clash and Clearance Modes
Each detection protocol supports two clash modes. Hard Clash mode identifies physical intersections between element solids, flagging situations where elements overlap in the model. Clearance mode identifies elements that do not intersect but fall within a user-defined minimum distance, measured in millimetres. This allows teams to detect both direct conflicts and spacing violations that may affect constructability, maintenance access, code compliance, or coordination requirements.
