Space-Saving Method of Installing Steel Columns

To improve safety with respect to the steel frame installation, the project has used concrete rings to maintain access to column bases to allow fixing without the need to form extensive 45 degree batters. Then after the column is installed, the inside of the ring is back filled like the finished site.

As part of the works undertaken on the £13m Percy Gee new build/ refurbishment project at the University of Leicester, there was a requirement to install steel columns on to foundation pads, which were located approximately four metres below ground level and within seven metres of the site boundary. With a confined site, which required the installation of a tower crane base along with the storage of all material required for the build adjacent to a live university square, a solution to reduce the amount of excavation and movement of material was required. It was vital to find a solution, as the project team did not want to have to encroach upon the space required for students, members of the public, and possibly emergency services to access the surrounding university buildings.

To overcome these issues, the team sought an alternative method utilising manhole rings with integrated ladder access as a form of shoring. Using this method, prior to the ground being prepared for MEWP access, manhole rings were placed to expose the holding down bolts in several locations. This allowed the rest of the area to be built up to the required ground level and remain structurally sound.
