From high strength permanent bridges to semi- permanent and moveable bridges, residential walkway bridges to multi-lane highway bridges, Chesterfield Associates has designed and built a variety of bridge projects.
Bridge styles developed by the company include vehicle bridges, pedestrian bridges, panel bridges and footbridges, in high, medium or low levels. The location for bridge building needs can vary from highway crossings, canals or rivers. Bridges can also be built for short term periods which are suitable for use on traffic reconstruction sites.
Traditional building materials used for bridge building are stone, timber, steel, and reinforced and prestressed concrete.
All have different qualities of strength, workability, durability and resistance against corrosion. They differ also in texture and color. Chesterfield Associates uses materials which result in quality and environmental compatibility. Well designed stone bridges can be the most cost effective. They are long lasting and need almost no maintenance. Prestressed concrete or reinforced concrete are less expensive than steel bridges and also require very little maintenance.
Steel has the highest strength and is often preferred. Lighter looking bridges may be built by joining slender steel sections together to form a truss. For bearings and some other items, cast steel may used.
Bridges are all constructed to meet safety regulation requirements and can include internal guardrails or anti-skid surfacing.
