structures + tunnels

The design of structures and tunnels have been an integral part of R.V. Anderson Associates Limited’s (RVA) engineering practice since the inception of the firm in 1948. Development of major infrastructure projects throughout Canada, and internationally, has given the firm unique experience. This history includes planning and implementation of tunnel schemes valued at more than $200 million and structural designs that suit a wide variety of applications and conditions.
