Guildhall - Great Hall Roof H&S Works

Tender description

The proposed works are comprised of high-level repairs to the Great Hall roof, to include: • Refurbishment of the central lantern and fleche • Isolated repairs on the Collyweston stone slate roof • Repairs and improvements to rainwater discharge • High-level masonry repairs and cleaning, to include clerestories, parapets, turrets, pinnacles and tracery • turrets, pinnacles and tracery • Re-bedding of gable copings with improved details • Installation of a new weathervane on the fleche The Great Hall and the wider Guildhall complex will remain operational throughout the works. The contractor’s compound will be located on the large, paved area immediately north of the Old Library. The Great Hall is enclosed by ambulatories on all sides, which prevents the use of full-height, ground-supported scaffolding. Consequently, scaffolding to the north and south elevations will need to be cradled from parapet level, while access to the east and west gables will require bridging over the ambulatories and bearing onto adjacent structures. An indicative scaffolding design and methodology have been developed and will be included within the tender documentation. This procurement will be conducted as a two-stage competitive process for the award of a below-threshold contract under the Procurement Act 2023. The process has been designed as a proportionate competition comprising an initial selection and shortlisting stage followed by an invitation to tender issued to shortlisted suppliers.
