Process And Cost Information:
Teams can begin this process by requesting a contract and a quote on the PHIUS website. Once the contract is sent in and payment is submitted, an account can be created. Upload documentation for initial review. Usually around 6-8 weeks later, teams will receive feedback. Respond to the first round of review, which may then need a few more rounds. Once the project meets the requirements it will earn pre-certified status. During the construction process, multiple site visits will be conducted. The PHIUS rater/verifier will then upload documentation, final review comments will be received, and certification will be awarded.
The pricing for PHIUS projects will depend upon the type of project and square footage on top of a base fee. Discounts are available for PHAUS Professional Members and non-profit owners or developers.
