HAKS provides expert architectural and engineering design, construction management/construction inspection, and surveying and mapping services for the rehabilitation and construction of vehicular and railroad tunnels. We design and oversee tunnel construction in geographically diverse locations and for a range of different purposes: urban and local roadways; interstate highway passages; subway and mass transit; suburban and long-haul railways; river and mountain traverses.  Our knowledge of tunnel excavation and construction technology and methods, and our experience with economical tunnel design and tunnel project management, ensure successful, high-quality completion of any type of tunneling construction, expansion or rehabilitation project.

HAKS’ transportation and infrastructure expertise enables us to understand how underground and burrowed passageways impact not just traffic but neighboring communities, the environment, area economies and natural vistas. HAKS merges this awareness with our geotechnical expertise and construction experience to carefully consider and design the right structure for a site.  During construction, HAKS expedites the work while efficiently ensuring maintenance and protection of traffic and rigorously enforces work zone safety.  Throughout the life of a project, our focus is on our client’s need for a job accomplished with minimal negative impact and optimal outcome.

Regardless of the size or scale of the project, our goal is to realize a functional, economical and aesthetical tunnel design that fulfills present needs, anticipates future growth and development, and is constructed on time and within budget.
