These details are mentioned in this guide, under each credit / mandatory requirement. Documentation is submitted in two bods design submittals and construction submittals v The design submission involves those credits which can be evaluated at the design stage. The reference guide provides the list of design and construction phase credits. After the design submission, review is done by third company assessors and review comments would be provided at bottom 40 operative days. v The undermentioned phase involves submission of clarifications to design queries and construction document submittal.The construction document is submitted on completion of the project.
