Construction Scheduling Considerations
Schedule installation and fill of the Freno™ System at a time when surrounding
surfaces have been stabilized and sedimentation is controlled. It is critical that the
bio-retention fill not become contaminated by sedimentation during construction.
A typical Freno™ installation will be completed rapidly (one to two days of
construction time per structure is typical, depending on complexity and size), but
some care should be taken if construction will be interrupted for any reason, or if the
surrounding site soils are not stabilized.
The planting soils should not be delivered to the site before the Freno™ System has
been installed and the under-drain system, if any, has been installed.
It may be most efficient to place the plant materials after paving has been
completed to avoid repetition of effort since performing the paving work may
require access from within the bio-retention area, which could damage the plant
materials.
The construction sequence is very straightforward:
