Registration and also expressing interest in a project using the Project Opportunities feature helps provide visibility of your company to active projects. It also provides the names of project contacts. It does not automatically place you on a potential bidders list. SLC does not maintain a company wide “formal” approved bidder list. Bidders are pre-qualified independently for each project based on project-specific requirements. You will only be contacted by a SLC project to review your qualifications when you are being considered for work on a project .
