CADD Example


CADD files for an example boardwalk with composite decking over timber bents on helical piles. Boardwalk has wood railings. Boardwalk bents are fairly close together and not high off the ground. Helical pile head fixity is made rigid by larger multi-bolt caps. This is an older style boardwalk design preferred by some for its rustic look. Magnum K-braces (see Other Foundation Products) are recommended for improved lateral bracing and lateral performance (anti-sway) where boardwalk deck height exceeds 30-inches above ground. Where boardwalk heights exceed 60-inches above grade, Magnum helical anchors installed at a 45 deg angle with MHC1080 tie-back caps clipped to the center of bents are recommended every other bent for lateral stability. Vehicular loads used to design this boardwalk are unknown and structural members should be checked by the design professional for project specific load conditions. Nonetheless, this example provides a glimpse as to how many boardwalks across wetlands and shallow water are constructed.
