About this asset

Engineered for gravity drainage systems, this grey Revit family represents a 90-degree access junction chamber with a flush square surface cover. The component features a cylindrical vertical chamber body terminating at a subterranean circular bore that routes pipe flow through a right-angled direction change. At ground level, a flush square access cover with an inset perimeter border provides a clean floor or pavement junction for inspection and rodding access. Rendered in a neutral matte grey tone, the model showcases clean geometric transitions between the round chamber barrel, circular inlet and outlet openings, and the rectangular surface frame, allowing clear visibility of underground drainage connections.

The download is a 604 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Load this plumbing component directly into Revit MEP or architectural models to coordinate subterranean pipe runs and slab penetrations. Position the junction along below-slab or external drainage lines, aligning the circular opening to connected pipework. The family provides essential physical geometry for interference checking, Clash Detection in Navisworks, and proper alignment with finished floor levels, exterior paving thresholds, or screed build-ups.

Designed for foul and surface water drainage layouts, this access fitting suits residential basements, commercial plant areas, parking structures, and exterior landscaping works. Specifiers and public health engineers can integrate the chamber into below-ground drainage schemes, wet area risers, and utility corridors. It pairs seamlessly with underground PVC or cast-iron soil pipes, cleanouts, gully traps, and floor drains across technical design and construction documentation phases.
