No. The project's construction schedule and its job creation are one timeline; USCIS processing of the I-526E and visa availability for the family's country of chargeability are another. The family can only move once the immigration timeline reaches a visa or approved adjustment, whatever the project promises.
Keep the project's dates and the government's dates on different pages
Sponsors describe timelines in terms of capital raise, construction and job creation, and those matter for whether the investment will ultimately support the removal of conditions. They say nothing about when the family can enter the United States as residents. That depends on how long the I-526E takes, which varies with the project type and USCIS priorities, and on whether a visa number is available in the Visa Bulletin for the family's charged country when the petition is approved.
Check the bulletin for the category and the country, and ask counsel how the family's chargeability is determined if a spouse was born elsewhere. Plan the sale of the Sainte-Catherine-de-la-Jacques-Cartier home, school enrolment and the transfer of the contractor's remaining business interests around the immigration milestones, with each step conditional on the one before. If the project's schedule slips, ask the sponsor in writing how that affects the job count that this family's petition depends on.
