Renovation of the Grade II listed Fry Building at the University of Bristol.
Overview
The Fry Building, led by Balfour Beatty and supported by Solum, underwent a complex renovation project aimed at modernising and expanding its facilities. The goal was to transform the existing structure into a modern hub for the School of Mathematics. The project encompassed the creation of a new main entrance, a raised external terrace, a 140-seat lecture theatre, and a new atrium. The confined nature of the courtyard, surrounded on three sides by the existing Fry Building, posed unique challenges that required innovative solutions. Solum’s core contributions to the Fry Building project encompassed the following scopes of work:
-
Underpinning & Excavation
To accommodate the proposed levels, a cut operation was executed in stages. A narrow pathway facilitated the movement of tipper lorries for the disposal of excavated material. The excavation process involved using a rock wheel mounted to an excavator, allowing for incremental removal of existing material beneath the building. As each level was completed, a working platform was lowered, and the underpinning process was repeated for two additional levels, resulting in a patchwork quilt effect beneath the century-old building.
-
Foundation & Retaining Wall Construction
Our team carefully laid reinforced foundations and concrete slabs, necessitating a delicate balance due to the confined space. We also constructed a 4-metre-high retaining wall, with all materials transported through the limited access provided by a small alleyway or crane.
-
External Works Completion
We completed the external works to the north plaza, included retaining walls and paving.
Challenges
The renovation of the Fry Building at the University of Bristol presented a range of challenges:
-
Constrained Site and Limited Access
The renovation was within a courtyard enclosed on three sides by the existing structure. Navigating the limited space posed a logistical challenge. Transporting the concrete and construction materials through the small alleyway or crane access required meticulous planning. The use of line pumps for concrete pumping and skips attached to a tower crane for material lifting over the building added another layer of complexity.
-
Fire Incident and Setback
One of the most significant setbacks was an accidental fire at the Fry Building caused by refurbishment works being carried out in the roof. This unforeseen event posed immediate safety concerns and halted progress on the project. Dealing with the aftermath required a reassessment of timelines, additional safety measures, and a second visit to the site.
