ISS were asked to to look at access scaffold for Craigallachie Bridge which is typically constructed from the ground up to the required height or suspended from the bridge’s structural steelwork.
The initial challenge was to create a detail that could handle the complete load from the entire scaffold we intended to suspend from the bridge. The subsequent challenge was to establish a method for providing our own access to install this detail, as there was no other means of reaching that area initially. Our approach involved installing the first set of tie tubes across the width of the bridge, after which we designed a cantilevered section to facilitate access to the next tie point, allowing us to install those ties and construct another cantilever section.
ISS engaged our fully qualified civil engineers to develop the scaffold designs and assess product capacities, the advanced scaffolder qualified management teams, along with site teams, are focused on evaluating the feasibility of the installation and determining whether the tube configurations can be effectively implemented in critical locations.
