1 Condition Survey & Recommendations for Repair St. Patricks Church, Donegall Street STONE CONSERVATION SERVICES CONSARC DESIGN GROUP 27 September 2012

2 ST PATRICKS CHURCH, DONEGALL STREET The current church was built on the site of an older church (constructed in 1815) that became too small for the expanding congregation. The construction of the current church was to the design of Timothy Hevey & Mortimer Thompson and the building was completed 1877. It is listed Grade B by the Northern Ireland Environment Agency. Damaged by fire in October of 1995 Reopened in October 1997 following repairs to the roof, external elevations and reconstruction of the Reredos and tabernacle. STONE CONSERVATION SERVICES CONSARC DESIGN GROUP St. Patricks Church, Donegall Street, Belfast

3 SURVEY The Condition Survey was carried out from a mobile hoist in March 2011. The tower and external facades were scanned by 3D Laser Scanning. The images were used to produce 2D CAD drawings of all elevations. The tower and spire is 54 m high and contains a 2 ton bell that was cast by Thomas Sheridan of Dublin. There was no internal access to the belfry and tower for inspection and maintenance. STONEWORK The church is constructed of coursed red rubble Dundonald Sandstone and Dungannon Sandstone (with Dunhouse Sandstone used as a replacement stone). Grey Armagh Limestone was used for the decorative columns as well as some detailing, while Portland Limestone was used for the sculpture of St. Patrick seen on the central tympanum.

4 Masonry so decayed it is loose and falling off STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Health & Safety Issues

5 STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Spalling Stonework

6 Stonework at and below the balcony levels of the tower in in particularly poor condition. STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Decaying Stonework

7 Deterioration of render repairs and fractures through coping stones STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Failing Masonry

8 Retreat of original stone Significant retreat of arrises and stone faces Loss of roll mould at string course A major issue is the loss of stone faces and arrises to all elevations. STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Major Decay of Stonework

9 Surface loss and significant loss of arrises a significant problem in buttresses STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Deterioration of Stonework

10 The defects identified during the survey were photographed and marked up on stone by stone drawings STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Stonework Repairs - Overview

11 STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Stonework Survey – In Detail

12 Example of stone detail to be produced for Tender Docs – SD04 View of stonework to tower. Significant cement mortar repair and cutting back of original detail STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Stonework Survey – Sample Tower Elevation

13 Summary of Defects Decay of the red Dundonald Sandstone to all elevations; Loss of detail to Dungannon sandstone dressings; Failing render repairs to rubble stone & window tracery; Original carved detail lost or removed. Above the doorway to the front elevation the carved detail has decayed significantly and in some cases loose and detaching; Biological growth to high level stonework STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Summary of Defects

14 Priority 1: Emergency Repairs: Defects that present a health & safety risk Priority 2: Essential Repairs: Replacement of deteriorated stone and failing render repairs with new natural stone to maintain a weathertight building and the structural stability of the existing structure. It is recommended that these repairs are carried out within 1-5 years. RISKS IF REPAIRS ARE NOT CARRIED OUT If the stonework to the facades is not repaired there will be a significant increase in the deterioration of the fabric and the occurrence of Priority 1 works. This will lead to more incidences of masonry fall and the requirement for façade inspections to remove unstable stone and render and further netting. With time the defects to the external fabric will also impact on the internal fabric of the church. Defects will allow water penetration through open joints and defective stone and damp ingress will increase and affect the internal fabric of the building. Recommendations STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Recommendations for Repair

15 Emergency Works – carried out this year Removal of loose material to front elevation Netting to front elevation Repairs to slate louvre Installation of ladder access Repairs to timber floors STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Emergency Work

16 Extent of Works The survey shows that the need for essential repairs to the external fabric of the church is extensive and cost is significant. Budget costs for all works to the church are in the region of £2 million excluding VAT and Fees. Therefore we propose a phasing of works starting with the tower. Phase 1: Spire and Tower – all elevations Stone repairs and repointing; Replacement of severely deteriorated stonework at the two balcony levels; Replacement of projecting stone elements to decorative cornices above the front entrance which are becoming loose and detaching; Cleaning and biocide treatment of stonework; Repairs to other slate louvres; Bird-proofing the tower; Upgrading of lightning protection to tower and spire Phase 1: Four Elevations of the Tower STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Phasing of Works

17 Phase 2: Lower façade of Front Elevation The Phase 2 repair scheme would include: Replacement of severely deteriorated stonework Re-pointing Repairs to limestone tynpanum Cleaning and biocide treatment Replacement of inappropriate storm glazing Replacement of cement at ground level Repairs to steps Installation of new disabled ramp STONE CONSERVATION SERVICES CONSARC DESIGN GROUP Phasing of Works

20 Sources of Funding NIEA (Northern Ireland Environment Agency) Currently not available for Grade B listed churches HLF (Heritage Lottery Fund) Current funding scheme available – maximum £100,000 available with a RESTRICTION of £250,000 on the total project costs. TWO submission dates - end September and March Approval usually takes up to 12 months. A formal tender process must be followed and work cannot start on site until approval is granted. The scheme is changing in December 2012 according to their website. The new scheme has a maximum of £250,000 available. LPOW (Listed Places of Worship VAT reclamation scheme) New scheme came into operation in March 2011. New scheme has a fixed budget and operates with fixed quarterly budgets and payments are made once a quarter. The maximum grant payable is 20% of project costs (VAT on fees is no longer eligible). The majority of repair works to St. Patricks Church are eligible for full VAT reclamation (20%), however, whilst the VAT reclamation scheme is open at present the future is uncertain and the scheme is reviewed annually.
