Construction and Rehabilitation Services

SEMA’s core service is the construction of structures. We build new bridges, and we rehabilitate or repair existing bridges. Our forte has always been railway structures. SEMA prides itself in having the people, the equipment, and the know-how to properly execute a given project successfully and safely for our various railway clients.

Railways bring with them their own unique set of requirements and the need for in-depth knowledge of how the railway works. SEMA prides itself on being able to come up with unique construction methodology solutions that help to reduce cost, bring a project in on time and budget, and maintain rail operations throughout the construction.

Our structural capabilities include:

  • Steel structures
  • Concrete structures
  • Timber structures
  • Culverts (steel, concrete, timber, plastic, lining)
  • Retaining structures
