When we do venture overseas, it is always for a U.S. Department of Defense client that has procured our services and expertise for a U.S. funded project abroad. Nova's resume of outstanding, quality, and safe projects in our niche markets is without equal. Nova also participates in several project delivery methodologies including: * Requests for proposals * Design/bid/build * Invitations to bid * Design/build * Indefinite delivery indefinite quantity (IDIQ), and Joint ventures with select strategic partners * Private, negotiated. Nova has acquired a state of the art hydraulic dredging fleet to both complement our waterfront operations and to provide environmentally sound maintenance dredging services.
