About Us

Manthos Engineering provides services for all project phases

Professional Engineering Consultants

Mr. Pericles Manthos established Manthos Engineering after serving Hawaii as Highways Administrator and later heading large mainland transportation initiatives for a multi-state private firm. He and his staff bring a wide range of experience in dealing with Program and Construction Management issues, from inception through completion.

Manthos Engineering have taken projects from conceptual design, through environmental documentation, design, cost analysis, scheduling, and construction management. Our understanding of all project aspects is key to our ability to meet client's goals for deadlines, cost, and quality control.


Sharing a common goal here in Hawaii - to implement projects in a culturally sensitve and environmentally sensitive community - it is important for Manthos Engineering to stay abreast of cultural issues and legislation affecting funding and eligibility guidelines. This enables the team to increase the effectiveness of agencies charged with developing and maintaining its projects.

Our mobility, responsiveness and commitment to our clients has been demonstrated by the successful performance of our staff on past assignments. We are in a people business, and realize that our product is only as good as the people we put on our projects, and that our company's longevity will always be dependent upon our clients' opinion of us. Consequently, we stress the quality of our staff and the importance of strong working relationships.
