RAAI has provided construction administration services as both a sub consultant and a prime consultant. As a sub consultant, we provide these services on a “upon request” approach of the prime consultant. As a Prime consultant, we conduct bi-weekly visits to the site. If a project is multi-site, we will split the project into thirds with different employees conducting the visits to their assigned site on a bi-weekly basis.

RAAI has two electricians, each with more than 10 years experience. Both function within our Field Division, performing full-time electrical inspection services for transportation related projects. These services have also been provided to state agencies and prime consultants as team members. The engineering design staff utilizes our electrical inspectors during field investigation phase of design task orders.
