The IEDC survey purports to be a cross-section of viewpoints, based on feedback from 301 people who work in economic development departments, local and state government and nonprofits.
Mr McCormack, La Societe Guernesiaise historic buildings section secretary, said he was happy with the department's response to the survey, but there were too many delays in the current system.
The survey work will move along the route in phases but, as it is taking place alongside a single carriageway section, traffic will be managed past the works by temporary traffic lights.
