GENERAL

Landscape plant materials including all trees, shrubs, and vines used in roadside development shall meet the minimum requirements of size and grade in the American Standard for Nursery Stock ANSI Z60.1, and the requirements of Article 4170. Acceptance for incorporation into a project will be based on a satisfactory report of inspection from the Resident Construction Engineer’s (RCE) Office, and a satisfactory field review from the Roadside Development Bureau.

INSPECTION & ACCEPTANCE

Field construction personnel will check the project for the size, quantity, location, alignment, and condition of plant materials. Field construction will provide a visual approval of the mulch and check to see that it is placed at the correct depth and area. It is intended that most of this can be accomplished through a general visual review of the project. Detailed inspection and measuring will only be required if there is a question of noncompliance. The information in the RCE’s project file will act as documentation for compliance with the materials requirement.

The contractor is responsible for ensuring that the species planted are correct and that they comply with the American Standard for Nursery Stock. The contractor shall submit invoices for plant materials to the RCE. The invoices shall list the species, size, and quantity of plant specimens.

Roadside Development Bureau staff will review the project for species compliance and plant survival rate. This review will take place in the fall. Roadside Development Bureau staff will document the review and copy the RCE, and the District Materials Engineer.
