Envision Environmental Cleanup Cost Models
Envision models cover a wide range of environmental cleanup activities and technologies. The cost relationship between cleanup activities and technologies that are usually performed or used together, are captured in each model or “Cost Estimating Relationship” (CER).
A CER is the lowest level of detail to estimate an cleanup activity or technology. The next level up is to combine CERs, which we call an Integrated CER or ICER. We’ve listed our ICERs and CERs below. We are releasing ICERs in bundles.
Join us beta testing online!
We are excited to announce that our upcoming beta testing will include the following cost models.
ICER library – a collection of 49 ICERs used to estimate entire cleanup phases. ( * = in beta test )
