Bridges
Our bridges are engineered using outside P.E. who considers site-specific issues while including feature requirements (length, width, weight requirements) within the design.
All steel structural members are Core Ten tubing featuring rust once surfaces so no paint necessary ever.
Our piling choices vary from site to site depending upon soil conditions, reach needed, cost and environmental concerns. Pilings available are H Type, Helical and Wooden. Typical applications or cost / benefit for each type are, H piling typically are more expensive but can be driven at a greater distance. Load is created by the friction generate from driving the pile into the ground.
H pile requires more soil control because of the size and support equipment necessary during installation. Helical pile typically is less expensive and less intrusive to soils than H pile. Twisting pile into the ground creating resistance generates helical pile loads. Disadvantage is reach to pile location. Wooden pile is the most cost effective but may require excavation and soil stabilization. Load is generated from surface contact of wood and soils.
