Manholes and shafts are critical to the construction and operation of tunnels and underground public utilities such as water pipelines, sewer pipelines, telecommunication and electricity lines, and oil and gas pipelines. SEERO provides exceptional manhole and shafts design services for roads, highways, and streets. Our shaft and manhole designs provide ventilation for highways, mass transits, and rail tunnels. Our shaft designs are usually elliptical or circular in nature for structural efficiency reasons, however, we can also design more complex geometries for particular shafts. We also software packages for modeling and simulation of our designs in real- time. Our designers and engineers have the expertise and experience to create cost-effective, robust, and long-lasting designs that meet the requirements of the clients.
