In support of our achievements in heavy construction, Civil Geometrics has developed a significant library of software tools specific to our industry. Some of these, such as transit alignment routines developed for work on the New York City transit system, evolved into commercial products that became widely used by the engineering community. Another set of tools handles complex spatial problems such as those involved in non-orthogonal 3-D pipe work and serves to fill the void where commercially available software leaves off. Still others are more job-specific but frequently see service in modified form on new projects. Collectively, these tools enable us to solve the most difficult problems facing our industry and to serve our clients with greater efficiency.
