The completed scheme provides a much-needed informal dining and social space for the college which fully capitalises on its scenic location on the banks of the River Cam. In addition to the construction of the Café space, we also carried out the renovation of the existing main and ancillary kitchens, as well as the renovation of student accommodation and improvements to the Buttery, including new flooring and refurbishment of toilets. Works included the provision of a new lift within the building, as well as a hidden external stair lift, rendering Old Court fully accessible for the first time in its history.
Methods of Construction:
The new extension is constructed using piled foundations with a ground bearing slab, cross laminated oak frame with infill cladding/brickwork and composite windows to the elevations. Roof works are a mixture of aluminium, zinc, single ply membrane and lead.
Internally, the new walls are constructed from both masonry and timber with whiterock in hygienic areas and paint finish to others. Flooring is a mixture of resin, vinyl, and stone tiling. All areas have been completed to an extremely high standard, with an emphasis on quality and longevity of materials.
Access to the works area was extremely challenging, with the enabling works required very complex. We;
To avoid delays associated with rescheduling the installation of the timber frame, we worked out of sequence and installed stone lintels after the frame was complete. To achieve this, we developed a solution in which the lintels were moved into Old Court via tower crane in advance of frame construction. A bespoke scaffold and metal cradle were used to move the lintels into position. Working out of sequence in this way avoided a 6-week programme delay.
Old Court is a Grade I listed building. In order to deliver the works successfully and sympathetically, we;
The North Passage is extremely as narrow, measuring 0.9m wide at points, which presented significant challenges in accessing and undertaking works. To manage this, we;
Our works required complex interfaces with an existing medieval chimney. 2 flues of the chimney were utilised to provide mechanical ventilation to the kitchens. In addition to this, we formed a permanent fire escape stairwell, the upper part of which passed through the chimney. To access the chimney to create the fire escape stairwell, we worked out of sequence, enabling us to install a scaffold to support the structure, as well as other complex temporary works.
Once the main works were complete and the bridge was demolished there was a significant amount of rubble remaining within the Master’s Garden. To remove this efficiently, we utilised a bespoke barge for transportation of the rubble across the River Cam and away from site.
Environmental and Waste Management:
Sustainability was at the heart of the scheme, with solar PV, a sedum roof, and wood fibre insulation throughout to compliment the high volume of laminated timber and bespoke timber panelling.
“The College have found working with Barnes on a day-to-day basis, to be easy, they are considerate, helpful and the staff are always engaged and polite (from the Banksman to the Site Manager). There have been no issues in working around an active College building, and additional issues presented by Covid have all been successfully managed. The College Health and Safety officer has been particularly complimentary of the Barnes set up and working methods.
The College has no hesitation in recommending Barnes Construction to work in a College environment. They are a proactive company, who have come on board with the College’s aims and sought to deliver the project in the most practical manner, while maintaining value for money.”
Deborah Hoy, Estates Director, Clare College.
