PHIUS+ Feasibility Study

Unsure if PHIUS+ Certification is feasible for your project? Need to supply documentation to government, funding, or granting agencies to demonstrate that your project can meet PHIUS+ standards? Order a Feasibility Study!

Please submit your project as early in the design process as possible to allow time for full design review and consultation during the design stage, and to accommodate on-site QA/QC protocols.

Contact the Certification Team at with any questions.

Step 2: Create Project in PHIUS Database & Upload Review Files

  • Log into the PHIUS+ Project Database using your CPHC login credentials.
    • If necessary, PHIUS will create an account or give you access to submit the project if you do not already have login credentials. PHIUS trained CPHCs will have already received their login details upon becoming certified.
  • Create a new project entry. This project entry will not become publicly visible until the project is pre-certified, so do not worry about entering project details at this time.

PHIUS Project DropBox

  • Once the PHIUS database project entry has been created, PHIUS will create a DropBox folder for the project and invite the Submitter to the folder. The Submitter may invite other members of the project team to the folder as well.
  • Upload project documentation into the appropriate sub-folders within the DropBox.
