We take pride in our work and it shows.
Keeping our projects on budget by incorporaing all of the team members.
Safety on the job site is our number one concern. We work hard on safety.
In engineering, a type of FOUNDATION most commonly used underwater for a bridge, but sometimes used in building construction. It is a large hollow structure that is sunk down through the earth by workers excavating from inside it; ultimately it becomes a permanent part of the PIER.
NTA was one of the first companies to specialize installing sumps, also know as drywells. We have the capability of excavating a 7.5' +/- diameter 37' deep excavation, with our one of a kind hydraulic clam machine. NTA is able to accomplish several jobs with one machine, such as: Surgically Precise Demolition, MH Over Existing Pipe, Caisson Manholes 14-20' Diameter, and Sumps / Sed Installs.
To ensure the optimum sump and storm sewer pipe performance, determine the in-place capacity of the sump downstream from the sedimentation manhole for each sump system. Testing takes place after a sump has been constructed.
Innovation on the Job Site creates opportunities for increased client satisfaction and project cost savings.
