  1. Falsework Guidance Dan Walsh

  2. Introduction • Falsework is a construction term meaning temporary support • CDOT did not consider the accident bracing to be falsework • Falsework has important design and planning implications

  3. Definitions of Falsework • CDOT – Supports vertical loads • AASHTO – Supports structural elements of concrete, steel, masonry, or other materials during their construction • FHWA – Supports the permanent structure until it becomes self-supporting • OSHA – No definition of falsework

  4. CDOT Specifications • CDOT did not consider the braces falsework • Did not support vertical loads • Had CDOT considered the braces falsework • CDOT would have required falsework drawings approved by a P.E.

  5. OSHA Regulations • No OSHA regulations for falsework • AASHTO and FHWA would have required falsework drawings • OSHA is what contractors typically look to for guidance

  6. Inconsistent Terminology • CDOT definition is narrow • FHWA and AASHTO definitions are broad • OSHA has no definition • Steel erectors may not be following appropriate guidance

  7. Summary • Inconsistent falsework definitions lead to inconsistent requirements • Causes planning and design without engineering input • Puts the public in jeopardy
