What to look for in a GSAS consultant
The most useful signals are credentials and track record. A GSAS-CGP (Certified Green Professional) credential shows working knowledge of the GSAS system, and hands-on experience preparing and submitting GORD documentation is what actually moves a project toward certification.
Ask how many GSAS Design & Build submissions the consultant has prepared end to end, and whether that experience covers both design and construction stages. A consultant who has only worked on one side will struggle to protect the rating through the build.

Design-to-construction breadth
GSAS is awarded on evidence from design and construction. The consultant you choose should be comfortable in both worlds: feeding requirements into design packages, and then verifying materials, submittals and site practice later. Breadth here is not a luxury, it is what protects your star rating when the design is finished.
The questions to ask before you sign
What target rating is realistic for this project and budget? Who prepares each document and who coordinates the specialists? How do you track submissions against the programme? What happens when a credit is at risk during construction? Clear answers to these tell you whether you are buying coordination or just paperwork.
What to avoid
Beware consultants who promise a rating without explaining the evidence, who have no direct GORD submission experience, or who treat sustainability as a document produced at the end. Certification is earned through the project, not recovered at handover.
